1. ボスニア・ヘルツェゴビナ

ボスニア・ヘルツェゴビナはクロアチア、セルビア、モンテネグロに囲まれ、ネウムに短いアドリア海沿岸を持つ南東ヨーロッパ西バルカンの山岳国です。交通は右側通行で、主要都市を離れると曲がりくねった道路、急勾配、変わりやすい天候が多くなります。冬季運転は特に重要で、ほとんどの車両は天候にかかわらず11月1日から4月1日まで指定された冬季装備を携行または装着する必要があります。

ボスニア語、クロアチア語、セルビア語が使用され、ラテン文字とキリル文字の両方が使われます。そのため道路標識の表記も両文字で示されることがあり、ボスニア・ヘルツェゴビナ連邦とスルプスカ共和国では表示順が異なる場合があります。主要交通規則は国家レベルで定められますが、高速道路網と料金徴収は各構成体が別々に管理しています。

2. 高速道路

高速道路は、自動車交通のために特別に設計され、標識で指定された道路です。通常、対向交通用の車道が分離され、指定された出入口によるアクセス制御があり、沿道施設への直接出入りや、他の道路・鉄道・通路との平面交差はありません。

高速道路では特別な交通規則が適用されます。利用できる道路利用者、速度制限、車線規則、通行料金、緊急時の手順は国によって異なるため、運転者は現地の交通標識と規則に従う必要があります。

How can you recognise a motorway?

A motorway is normally identified by a special motorway sign at its entrance. It commonly has separate carriageways, controlled entrances and exits, and no ordinary intersections or direct access to neighbouring properties.

Who may use a motorway?

Motorways are primarily intended for motor vehicles capable of travelling safely at motorway speeds. Pedestrians, cyclists, animals and certain slow vehicles are generally prohibited, but the exact access requirements differ between countries.

What is the speed limit on a motorway?

There is no universal motorway speed limit. The applicable limit depends on the country, road section, vehicle category and driving conditions. Posted or variable speed-limit signs may replace the general national limit.

How should you enter a motorway?

Use the entrance or acceleration lane to observe motorway traffic and adjust your speed where possible. Enter only when there is a safe gap and follow the local priority and merging rules.

How should you leave a motorway?

Move into the correct lane in good time and signal when required. Enter the exit or deceleration lane before reducing your speed, unless traffic, signs or road conditions require you to slow down earlier.

Which lane should you use on a motorway?

Follow the local keep-left or keep-right rule and any lane-direction signs. Lanes closer to the centre of the motorway are commonly used for overtaking, but lane-use rules differ between countries and vehicle categories.

Can you stop on a motorway?

Voluntary stopping and parking are normally permitted only in designated parking or service areas. Drivers may still have to stop because of congestion, an emergency or another unavoidable situation.

Can you reverse or make a U-turn on a motorway?

Reversing, making a U-turn and driving against the direction of traffic are generally prohibited. If you miss an exit, continue to the next suitable exit.

What should you do if your vehicle breaks down?

Move the vehicle out of the traffic lanes when this can be done safely, activate the hazard warning lights and follow the local breakdown procedures. Leave the vehicle safely, keep away from moving traffic and use a warning triangle or safety vest where required by local law.

What is the difference between a motorway and an expressway?

A motorway normally has the highest level of access control and is governed by specific motorway rules. An expressway may have similar characteristics but may permit different road users or contain lower-standard junctions. The legal distinction varies between countries.

3. 岸壁

岸壁は、港、運河、河川、その他の水辺に沿って設けられ、船舶の接岸や貨物・旅客の取扱いに使われる場所です。道路が岸壁沿いを通る場合、車両は水際のすぐ近くを走ることがあります。

運転者は保護柵のない水際、港湾作業、歩行者、貨物車両に注意し、速度制限や進入規制に従う必要があります。濡れた路面、強風、夜間の視界にも注意します。

岸壁
What is a quay?

A quay is a constructed waterside platform or road area beside a river, canal, harbour or other navigable water. It may be used by ships, vehicles, workers, pedestrians and loading equipment.

What does a quay warning sign mean?

It warns that the road approaches or leads onto a quay, riverbank or waterside edge where a vehicle could enter the water.

Does the sign mean that the road ends at the water?

It may. The road may lead directly towards the water, turn sharply near it or continue alongside an insufficiently protected edge. Drivers must observe the actual road layout.

How should you approach a quay?

Reduce speed early, remain in full control and watch for the road edge, barriers, bends, workers, pedestrians and moving equipment. Avoid sudden steering or braking close to the water.

Is there a universal speed limit near a quay?

No. Drivers must follow the posted or general speed limit and reduce their speed further when the road is narrow, wet, poorly lit or close to an unprotected edge.

Does a quay warning sign impose a prohibition?

No. It normally warns of danger rather than prohibiting access. Additional signs, gates or local rules may restrict particular vehicles or activities.

Does the sign change priority?

No. Drivers must continue to follow traffic lights, priority signs and the normal priority rules.

May you stop or park on a quay?

This depends on local signs and regulations. Do not stop or park where the vehicle could create danger, obstruct traffic, interfere with loading operations or block emergency access.

Should you park close to the water’s edge?

Only in a clearly authorised and suitable place. Leave sufficient space from the edge, apply the parking brake securely and follow any wheel-positioning or local parking instructions.

May you overtake near a quay?

Overtaking may be legal, but it should be avoided when the road is narrow, visibility is limited or the manoeuvre would bring the vehicle close to the waterside edge.

Why can quay surfaces be slippery?

Water, algae, mud, ice, fuel, oil or material from loading operations may reduce grip. Painted markings, rails and metal surfaces may also become especially slippery when wet.

What other hazards may be present on a quay?

Drivers may encounter pedestrians, cyclists, dock workers, cranes, forklifts, railway tracks, mooring equipment, reversing trucks and unsecured edges.

Why should large vehicles take extra care?

Large vehicles need more space to turn and may have limited visibility close to the cab or trailer. Soft edges, narrow roads and nearby equipment can make manoeuvring more difficult.

May pedestrians walk on a quay?

Pedestrian access depends on local rules. Where pedestrians are permitted, drivers should expect them to move between vehicles, vessels, buildings and loading areas.

Should you reverse near a quay edge?

Reverse only when necessary and when the route is clearly visible. Use a guide where available and never rely solely on mirrors or cameras when the vehicle could approach the water.

What should you do in darkness or poor visibility?

Reduce speed, use the required lights and look carefully for reflectors, barriers, road edges and people. Water and dark surroundings can make the boundary of the road difficult to recognise.

What should you do if a barrier is open or missing?

Do not assume that the route is safe. Slow down, identify the road boundary and follow signs or instructions from authorised personnel.

What should you do if a vehicle enters the water?

Leave the vehicle as quickly and safely as possible, help passengers where possible and contact the emergency services. Do not re-enter the water or vehicle to recover belongings.

4. 譲れ

譲れ標識は、運転者に速度を落とし、必要に応じて停止して、優先権を持つ道路利用者へ道を譲ることを求めます。一般に逆三角形の標識が使われます。

必ず完全停止する必要はありませんが、安全に進めない場合は停止しなければなりません。どの交通に譲るかは交差点の構造、標識、現地の優先規則によって決まります。

譲れ
What does a give-way sign mean?

A give-way sign requires drivers to allow traffic with priority to proceed first. The driver must slow down and stop when necessary.

How can you recognise a give-way sign?

It is commonly an inverted triangular sign with a red border and a light-coloured centre. In some countries, it is called a yield sign.

Must you always stop at a give-way sign?

No. You must stop only when necessary to give way or obtain a sufficiently clear view. You may continue slowly when the road is clearly free.

What does giving way mean?

Giving way means allowing another road user to continue without being forced to brake, accelerate, stop or change direction because of your movement.

Where should you stop when necessary?

Stop before the give-way line where one is provided. Without a line, stop before entering the intersection or priority road at a position where you can observe traffic safely.

May you cross the give-way line before stopping?

You may move beyond the line only when this does not interfere with traffic that has priority. Where visibility is limited, first slow or stop at the line and then move forward cautiously.

What is the difference between give way and stop?

A stop sign always requires a complete stop. A give-way sign permits the driver to continue without stopping when the road is clearly free and it is safe to proceed.

Does slowing down satisfy the give-way requirement?

Only when slowing down is sufficient to let all priority traffic proceed safely. If another road user would be hindered, the driver must slow further or stop.

Who must you give way to?

Give way to traffic travelling on the road being entered or crossed and to any pedestrians, cyclists or other road users who have priority under the applicable rules.

Does giving way apply only to vehicles approaching from one direction?

No. Check every direction from which lawful traffic may approach, including cycle paths, one-way roads with authorised contraflow traffic and separate carriageways.

Does a give-way sign give the other road permanent priority?

The sign determines priority at the particular location. The priority arrangement at later intersections may be different unless the road is separately identified as a priority road.

Does giving way give you priority afterwards?

No. You may proceed only when it is safe. Another driver’s hesitation or courtesy does not remove your responsibility to avoid danger.

Must every vehicle in a queue give way separately?

Yes. Each driver must observe the road and make an individual decision. You may not follow another vehicle through without checking that the way remains clear.

Does a give-way sign apply to cyclists?

Normally, yes. Cyclists are generally treated as drivers and must obey the sign unless a supplementary sign or local rule provides otherwise.

Can a give-way sign apply only to cyclists?

Yes. Some countries use supplementary signs or path-specific signs to require cyclists to give way while other traffic follows a different priority arrangement.

Does a give-way sign change the speed limit?

No. It regulates priority rather than speed. Drivers must still approach slowly enough to observe traffic and stop when necessary.

Does a give-way sign change turning rules?

No. Drivers must still obey traffic lights, lane arrows, mandatory-direction signs and turning prohibitions.

How does give way work at a roundabout?

Many roundabout entrances have give-way signs requiring entering traffic to yield to vehicles already circulating. Drivers must follow the actual signs because roundabout priority rules differ between countries.

Do traffic lights override a give-way sign?

Functioning traffic lights commonly take precedence over priority signs controlling the same movement. The give-way sign may apply again when the lights are switched off or flashing, depending on local law.

Do police instructions override a give-way sign?

Yes. Instructions from an authorised traffic officer normally take precedence over traffic signs and ordinary priority rules.

What should you do when visibility is limited?

Reduce speed substantially and stop when necessary. Move forward cautiously only after giving way and checking that the road can be entered without danger.

5. ラウンドアバウト

ラウンドアバウトは、中央島の周囲を一方向に循環し、複数の道路が接続する交差点です。進入交通の速度を下げ、交差点内の交錯点を減らすよう設計されています。

進入時の優先関係、車線選択、合図方法は国によって異なります。運転者は進入口の優先標識、車線矢印、路面表示に従い、退出時は歩行者や自転車にも注意する必要があります。

What is a roundabout?

A roundabout is a circular road arrangement where traffic travels in one direction around a central island before leaving through the chosen exit.

How can you recognise a roundabout?

A roundabout is normally identified by a circular-direction sign, a central island and entry roads controlled by signs, markings or local priority rules.

Which direction does traffic travel around a roundabout?

The direction depends on the country’s driving side. Traffic normally travels anticlockwise in right-hand-traffic countries and clockwise in left-hand-traffic countries.

Who has priority at a roundabout?

Priority differs between countries and roundabout designs. Entering traffic commonly gives way to traffic already circulating, but drivers must always follow the actual priority signs and signals.

Must you stop before entering a roundabout?

Not always. Stop when required by a stop sign, traffic light or approaching priority traffic. Otherwise, reduce speed and enter only when there is a safe gap.

Does a roundabout always have a give-way sign?

No. The sign arrangement depends on local law. Some circular intersections use ordinary priority rules or traffic lights instead.

How should you approach a roundabout?

Reduce speed, observe the signs and markings, choose the appropriate lane and check for pedestrians, cyclists and circulating traffic.

Which lane should you choose?

Follow the lane arrows and destination signs. As a general guide, use the lane appropriate for your exit, but exact lane-selection rules differ between countries and roundabout layouts.

May you use an inner lane?

Yes, where the road layout and local rules permit it. Before leaving, change lanes safely and give way to road users already travelling in the lane you wish to enter.

Do you need to signal when entering?

This depends on local law. Some countries require a signal for particular exits, while others require no signal when entering.

Do you need to signal when leaving?

Usually, yes. Signal in the direction of the exit early enough to inform other road users, but not so early that your intention becomes misleading.

Does signalling give you priority?

No. A direction indicator communicates your intention but does not permit you to force another road user to brake or change direction.

May you change lanes on a roundabout?

Only when the lane markings permit it and the manoeuvre can be completed safely. Check mirrors and blind spots, signal where required and give way to traffic already in the target lane.

What should you do if you miss your exit?

Continue around the roundabout and approach the exit again. Do not stop, reverse or cut suddenly across another lane.

May you drive over the central island?

Normally not. Some small roundabouts have a mountable central section intended only for vehicles that cannot otherwise negotiate the road safely.

Do cyclists have priority at a roundabout?

Priority depends on whether cyclists use the carriageway, a continuing bike path or a separate cycle crossing. Drivers and cyclists must follow the signs, markings and local priority rules.

What should drivers check before leaving?

Check mirrors and blind spots for cyclists, mopeds, motorcycles and vehicles beside you. Also check for pedestrians crossing the exit road.

Do pedestrians have priority at roundabout exits?

Pedestrian priority depends on crossings and local law. Drivers should approach exits slowly and be prepared to yield to pedestrians crossing or about to cross.

Does a roundabout have a special speed limit?

Not universally. The posted or general road limit applies, but drivers must travel slowly enough to negotiate the roundabout safely.

May you overtake on a roundabout?

Passing another vehicle may be permitted on a multilane roundabout, but drivers must remain within their lane and avoid unsafe lane changes. Local overtaking restrictions may apply.

May you stop or park on a roundabout?

Follow local signs and parking rules. Stopping or parking on the circulating roadway is commonly prohibited or unsafe because it obstructs traffic and reduces visibility.

Is every circular intersection a roundabout?

No. A circular junction may be governed by traffic lights, ordinary priority rules or another road design. Its legal status depends on its signs and local definition.

6. 踏切

踏切は、道路または通路と鉄道線路が同じ高さで交差する場所で、level crossingやrailroad crossingとも呼ばれます。遮断機、警報灯、警報音、標識などで保護される場合があります。

道路利用者は慎重に接近し、列車が接近している場合、警報が作動している場合、出口側が塞がれている場合は進入してはいけません。速やかに横断し、線路上で停止、待機、立ち往生してはなりません。

踏切
What is a railway crossing?

A railway crossing is a place where a road or path crosses railway tracks at the same level.

What is another name for a railway crossing?

It may also be called a level crossing or, particularly in North America, a railroad crossing.

How can you recognise a railway crossing?

It may be indicated by warning signs, crossbuck signs, barriers, flashing lights, bells or road markings. The design differs between countries.

What is the difference between a crossing with and without barriers?

A protected crossing uses full or partial barriers to block road traffic when a train approaches. A crossing without barriers relies on signs, lights, bells or the road user’s own observation.

Must you always stop at a railway crossing?

Not necessarily. You must stop when required by lights, barriers, signs, an approaching train or an authorised person. At an unprotected crossing, slow down and proceed only after checking that no train is approaching.

What do flashing red lights mean?

Flashing red lights mean stop and do not enter the crossing. Remain stopped until the signal permits you to continue.

May you cross while a barrier is moving?

No. Do not enter while a barrier is lowering, rising or closed. Wait until the crossing is fully open and all prohibiting signals have stopped.

May you drive around a closed barrier?

No. Never drive, cycle or walk around or underneath a closed or moving barrier.

What does a warning bell mean?

A warning bell or audible signal normally means that the crossing is closing or that a train is approaching. Do not enter the crossing while it is sounding.

What does a flashing white light mean?

In some countries, a flashing white light indicates that the crossing equipment is operating and road users may pass when the route is clear. Its exact meaning depends on local law.

What should you do at a crossing without lights or barriers?

Reduce speed, look and listen carefully in both directions and cross only after making sure that no train or other rail vehicle is approaching.

May you cross immediately after a train has passed?

Not automatically. Another train may approach on a second track. Wait until all warning signals stop and the crossing is fully open.

What if traffic ahead is blocking the exit?

Do not enter the crossing unless there is enough room beyond the tracks for your entire vehicle. Never rely on traffic moving before a train arrives.

May you wait on the tracks?

No. Railway tracks must always remain clear. Do not stop because of congestion, traffic lights or another obstruction beyond the crossing.

May you overtake at a railway crossing?

Overtaking is often prohibited or restricted because another vehicle can obstruct the view of an approaching train or warning signal. Follow local signs and overtaking rules.

May you stop or park on a railway crossing?

No. Stopping or parking on the tracks creates an immediate and potentially fatal danger.

Do the crossing signals apply to pedestrians and cyclists?

Yes. Pedestrians and cyclists must obey barriers, lights, bells and authorised personnel in the same way as other road users.

Should cyclists ride across the tracks at an angle?

Where possible, cross the rails at an angle close to 90 degrees. Rails can trap a bicycle wheel, especially when they are wet or cross the road diagonally.

What should drivers of long vehicles check?

Make sure the entire vehicle and any trailer can clear the crossing without stopping. Consider the available space, road gradient, turning room and traffic beyond the tracks.

What should drivers of high vehicles check?

Observe all height restrictions and warning signs. Electrified railway lines may have overhead equipment that can be struck by an excessively high vehicle or load.

What should you do if the signals appear defective?

Treat the crossing with extreme caution. Do not assume that no train is approaching merely because the lights or barriers are not operating.

What should you do if your vehicle becomes stuck on the tracks?

Evacuate everyone immediately, move well away from the railway and contact the emergency services or railway operator. Do not remain in the vehicle or return for belongings.

Is a railway crossing the same as tram tracks in the road?

Not always. A railway crossing normally crosses tracks that are separate from the carriageway, while tram or street-running railway tracks may form part of the road itself.

7. 信号機

信号機は、色灯、矢印、記号によって道路利用者が進行できる時、停止準備をする時、停止し続ける時を規制します。進行方向、車線、歩行者、自転車、公共交通ごとに別の信号がある場合があります。

青信号でも、進路が空いており、その動きが法的に許可される場合にのみ進めます。優先規則、右左折制限、車線表示、交通整理員の指示にも従う必要があります。

信号機
What are traffic lights?

Traffic lights are signals that use coloured lights, arrows or road-user symbols to regulate traffic movements.

What does a red traffic light mean?

A red light requires road users to stop before the stop line or signal and remain stopped until movement is permitted.

What does a steady amber light mean?

A steady amber light normally requires drivers to stop unless they are already too close to stop safely. It warns that the signal is changing to red.

What does a green traffic light mean?

A green light permits road users to pass the signal, but only when the route is clear and the intended movement is otherwise legal.

Does green mean that you have priority over everyone?

No. You may still have to give way to pedestrians, cyclists, oncoming traffic or other road users when turning or following a conditional arrow.

May you enter a blocked intersection on green?

No. Do not enter when congestion is likely to leave you stopped inside the intersection and obstructing crossing traffic.

Where should you stop at a red light?

Stop before the stop line. When no stop line is provided, stop before the traffic light or at another legally prescribed position.

May you cross the stop line and then stop?

No. The required stop must normally be completed before the stop line. Do not stop on a pedestrian or cycle crossing.

What if the light changes to amber while you are approaching?

Stop when this can be done safely. Continue only when you are already too close to stop without creating danger.

Should you accelerate to pass an amber light?

No. Do not accelerate to avoid stopping. Maintain control and stop unless doing so safely is no longer possible.

What do arrow-shaped traffic lights mean?

They have the same general meaning as circular lights, but the prohibition or permission applies only to the direction shown by the arrow.

What does a green arrow displayed with a red light mean?

It may permit travel in the indicated direction while other movements remain prohibited. Drivers may still have to give way to conflicting traffic and pedestrians.

Does a green arrow override a no-turn sign?

Not universally. Drivers must follow the complete local sign arrangement. A traffic signal does not necessarily cancel a separate regulatory prohibition.

May you turn right on red?

Only where local law or a specific sign or signal expressly permits it. There is no universal right to turn on red.

What does a flashing amber light mean?

It warns of a potential hazard and normally allows cautious passage. The ordinary priority arrangement remains applicable.

What should you do when the normal lights are flashing amber?

Reduce speed, observe the intersection carefully and follow the applicable priority signs or default priority rules.

What does a flashing red light mean?

Its meaning depends on local law. At railway crossings and some movable bridges, flashing red lights normally require road users to stop.

What do lane-control signals mean?

A red cross normally closes the lane, a green downward arrow opens it and an amber diagonal arrow instructs drivers to leave the lane in the indicated direction.

May you continue beneath a red lane-control cross?

No. Move out of the lane safely before reaching the red cross unless an authorised person or emergency rule directs otherwise.

What does an amber diagonal lane arrow mean?

It warns that the lane is closing or unavailable ahead. Drivers must move into the adjacent lane indicated by the arrow when safe.

Can separate lights apply to cyclists?

Yes. A signal displaying a bicycle symbol applies to the road users legally covered by that signal rather than to general motor traffic.

Can separate lights apply to pedestrians?

Yes. Pedestrian lights normally use red and green human figures to indicate whether pedestrians may begin crossing.

What does a flashing green pedestrian light mean?

It normally warns that the crossing period is about to end. Pedestrians who have not started should wait for the next green signal.

What if the pedestrian signal changes while someone is crossing?

A person who entered lawfully should continue without unnecessary delay. Turning drivers must allow the crossing to be completed safely.

Can buses and trams have separate traffic lights?

Yes. Public-transport signals may use bars, circles, triangles or other symbols that apply only to authorised service vehicles.

Do functioning traffic lights override priority signs?

They commonly replace the priority arrangement at that location. Priority signs may apply again when the normal signals are inactive or flashing.

Do instructions from a police officer override traffic lights?

Yes. Instructions from an authorised traffic controller normally take precedence over lights, signs, markings and ordinary rules.

What should you do when the lights are not working?

Reduce speed and follow the priority signs, temporary signals, authorised personnel or default priority rules that apply.

May you clear an intersection after the light turns red?

Yes, when you entered lawfully and must leave the intersection. Complete the movement cautiously without endangering other road users.

Does a green light impose a minimum speed?

No. Drivers may proceed but must continue at a safe and legal speed.

May you use a handheld phone while waiting at red?

This depends on local law. In many countries, a driver temporarily stopped in traffic is still considered to be driving and may not use a handheld device.

8. 国境

国境は2つの国の法的境界です。国境標識は進入する国を示し、交通法規、速度制限、道路標識、車両要件、必要書類が変わることを運転者へ知らせる場合があります。

国境標識自体が通常停止を義務付けるわけではありません。旅券、入国、税関検査が検問所で行われる場合もあれば、地域協定により通常検査なしで越境できる国境もあります。

国境
What is an international border?

An international border is the legal boundary between two countries.

How can you recognise an international border?

It may be identified by a country-name sign, national or regional symbols, flags, border posts, customs facilities or passport-control signs.

Does every international border have a road sign?

No. Borders may be marked differently, and some minor roads or open-border areas may have only a small identification sign or boundary marker.

Does a border sign require you to stop?

Not normally. Stop only when required by traffic lights, barriers, officers, customs signs, passport controls or another instruction.

When do the destination country’s traffic rules begin?

The new country’s traffic laws apply from the international boundary, not merely from the next town or major intersection.

Does the border sign itself impose the new rules?

No. The rules change because you have entered another country. The sign identifies that change of jurisdiction.

Can the driving side change at a border?

Yes. Where neighbouring countries use different driving sides, a specially designed road arrangement guides traffic safely from one side to the other.

Can speed limits change at the border?

Yes. The destination country may have different general limits for motorways, built-up areas, rural roads and particular vehicle categories.

Is the border sign a speed-limit sign?

No. Drivers must learn the destination country’s general limits and obey any regulatory signs displayed after crossing.

Can traffic-sign designs change?

Yes. Colours, symbols, shapes and road-marking conventions may differ, even when neighbouring countries follow similar international standards.

Can vehicle-equipment requirements change?

Yes. Requirements concerning safety vests, warning triangles, winter tyres, lights, toll equipment or environmental stickers may differ between countries.

Which documents may be required?

Depending on the journey, drivers may need a passport or identity card, driving licence, vehicle-registration document, insurance evidence, visa or customs documents.

Is a border check the same as customs control?

No. Border or immigration control concerns people and travel documents. Customs control principally concerns goods, cargo, money and applicable duties or restrictions.

Can immigration and customs controls occur together?

Yes. Both may operate at the same border facility even though they perform different legal functions.

Does every border have passport control?

No. Countries participating in an open-border area may normally cross internal borders without routine checks, although temporary controls may still be introduced.

Does every border have customs control?

No. Countries within a customs union may allow goods to move across their internal borders without ordinary customs duties or routine customs formalities.

Is an open border completely uncontrolled?

No. Police, customs and other authorities may still conduct lawful checks, enforce national rules and temporarily control the border where permitted.

May you cross the border anywhere?

Only where local law permits it. External or controlled borders may have to be crossed through an authorised border-crossing point during its operating hours.

Can a border crossing be temporarily closed?

Yes. Closures or restrictions may result from security measures, emergencies, severe weather, roadworks or administrative decisions.

Can certain vehicles be restricted?

Yes. A crossing may restrict heavy vehicles, dangerous goods, agricultural traffic, pedestrians or cyclists because of road design or border-control facilities.

May goods have to be declared?

Yes. Commercial goods, restricted products, goods exceeding personal allowances and certain amounts of cash may require declaration.

Do tolls or road charges change at the border?

They may. The destination country may use toll roads, vignettes, distance-based charges, low-emission zones or other payment systems.

Should you rely only on navigation software?

No. Navigation information may not include current border controls, vehicle restrictions or document requirements. Follow official signs and instructions.

What should you do before an international road journey?

Check the destination and transit countries’ traffic rules, required documents, insurance, vehicle equipment, tolls and border or customs requirements.

Do instructions from border officers override ordinary signs?

Yes. Follow lawful instructions from authorised border, police and customs officers, even when they temporarily differ from the normal traffic arrangement.

9. 後退

後退は車両を後ろ向きに動かすことです。駐車、狭い場所から出るとき、前進では位置調整できない場合などに使われます。

後退前にミラーと死角を確認し、車両周囲をよく見て後方が空いていることを確かめます。後方視界は限られるため、ゆっくり、必要な距離だけ後退します。

後退
What should you check before reversing?

Check behind and around the vehicle for pedestrians, cyclists, other vehicles and obstacles. Use mirrors and cameras where available, but also look directly because monitoring systems can have blind spots.

Who has priority when a vehicle is reversing?

In many countries, reversing is treated as a manoeuvre and the reversing driver must give way to other road users. The exact legal requirements depend on national traffic rules.

Should you reverse for a long distance?

No. Reversing should normally be limited to the distance necessary to complete the manoeuvre safely. Driving forward generally provides better visibility and vehicle control.

10. 市街地境界

市街地境界は、道路交通上、市街地・都市区域が始まるまたは終わる境界です。地名標識や市街地標識で示され、都市速度制限、駐車規則など特別規則の開始・終了地点となることがあります。

交通上の市街地境界は自治体の行政境界と必ずしも一致しません。法的意味はその国の道路標識と交通規則によります。

What is a city limit?

A city limit marks the boundary of a city, town, village, locality or municipality. On roads, it is often indicated by a place-name or boundary sign.

Does a city-limit sign always mark a built-up area?

No. A city-limit or locality sign may simply identify a place or administrative boundary. A legally defined built-up area can use a different sign or definition.

Does passing a city-limit sign always change the speed limit?

No. In some countries a locality or boundary sign has consequences for traffic rules, while in others it mainly identifies the place. Drivers must follow the traffic signs and rules that apply in that country.

Is a city limit the same as a municipal boundary?

Not always. Some signs indicate an administrative municipal boundary, while others identify a city, town, village or locality without exactly following the municipality's legal boundary.

What is the difference between a city limit and a built-up area?

A city limit identifies the boundary of a named place or administrative area. A built-up area is a traffic-law concept that may affect rules such as default speed limits. The two boundaries can coincide, but they do not have to.

11. 観光地

観光地は、文化、歴史、レクリエーション、自然、娯楽などを目的に訪問者が向かう場所です。記念碑、城、博物館、景勝地、遊園地などが含まれます。

目的地への案内には観光標識や方面案内標識が使われます。色、記号、表示される施設の種類は国によって異なります。

What is a bus?

A bus is a motor vehicle designed to transport a relatively large number of passengers. It may be used for public transport, school transport, private services or other passenger transport.

What is the difference between a bus and a coach?

A bus is commonly designed for frequent passenger boarding and may allow standing passengers, while a coach is generally designed for longer journeys with passengers seated. Exact legal definitions vary between countries.

Do you need a special driving licence to drive a bus?

Yes. Driving a vehicle designed to carry more than a specified number of passengers normally requires a dedicated bus or passenger-vehicle driving licence.

Can passengers stand on a bus?

Only when the vehicle is designed and approved to carry standing passengers. Coaches and other vehicles designed exclusively for seated passengers must not be used beyond their approved passenger configuration.

Must bus passengers wear seat belts?

Where seat belts are provided and local law requires their use, passengers must wear them correctly. Urban buses designed for standing passengers may have seating positions or operating conditions that differ from coaches.

Can buses use bus lanes?

Yes, where permitted. Bus lanes are commonly reserved for public transport buses, although local signs may also allow taxis, bicycles or other specified vehicles to use them.

Do buses always have priority when leaving a bus stop?

No. Some countries require other drivers to give way to buses leaving designated stops, particularly in urban areas, while others apply the normal merging rules.

Should you take extra care near a stopped bus?

Yes. Passengers may be boarding, leaving or crossing the road near the bus. Reduce speed where necessary and watch carefully for pedestrians emerging from behind or in front of the vehicle.

Do buses have special speed limits?

They can. Some countries impose lower maximum speeds on buses than on passenger cars, particularly on high-speed roads. Different limits may apply to buses and coaches.

Can a bus use a motorway?

Yes, normally. Buses that satisfy the applicable construction and access requirements may use motorways, but they must obey any vehicle-specific speed limits, lane restrictions and other local rules.

13. 警察

警察は、法律の執行、公共安全、道路交通へ影響する状況の管理を担う公的機関です。交通では車両検査、交通取締、事故調査、交通整理、緊急対応などを行います。

道路利用者は警察官など権限を持つ交通整理員の適法な指示に従います。現地法により、警察の指示は一時的に信号、道路標識、通常の交通配置より優先する場合があります。

警察
What is the role of police in road traffic?

Police help enforce traffic laws, manage traffic, investigate collisions and respond to dangerous situations. They may also carry out roadside checks and direct road users.

Must you obey a police officer directing traffic?

Yes. Lawful directions given by an authorised police officer must be followed. In many countries, those directions take precedence over traffic lights, road signs and normal priority rules.

What should you do if police signal you to stop?

Slow down, follow the officer's directions and stop at a safe location as instructed. Do not make sudden movements or continue driving unless directed to do so.

Can police direct you through a red traffic light?

Yes, where authorised by local law. A police officer controlling traffic may instruct road users to proceed even when a traffic light or sign would normally require them to stop.

Can police check your driving documents?

Yes. Police may require drivers to provide documents such as a driving licence, vehicle registration, identification or proof of insurance according to local law.

Can police carry out alcohol or drug checks?

Yes. Traffic police may conduct legally authorised alcohol and drug checks using procedures such as breath, saliva or other approved tests.

Can police temporarily close a road?

Yes. Roads or lanes may be temporarily closed or traffic diverted because of collisions, emergencies, investigations, public events or other safety concerns.

What should you do near police controlling an accident scene?

Reduce speed, remain alert and follow all directions. Do not enter a closed area or interfere with emergency personnel, and leave sufficient space for emergency vehicles.

What should you do when a police vehicle approaches with emergency signals?

Follow the local rules for priority vehicles. Drivers generally have to make sufficient space, give way and stop where necessary so that the emergency vehicle can pass safely.

Can police order a parked vehicle to be moved?

Yes, where local law permits it. Police or another authorised authority may require a vehicle to be moved when it obstructs traffic, creates danger or must be removed for operational reasons.

14. 救急車

救急車は、緊急医療の提供や患者輸送のため装備・使用される車両です。医療機器と訓練された職員を乗せ、搬送中に治療する場合があります。

緊急出動中は警光灯とサイレンを使用し、特別な優先権や一部交通規則の例外が認められる場合があります。他の道路利用者は現地規則に従い、十分な通路を空け、進行を妨げない必要があります。

救急車
What is an ambulance?

An ambulance is a specially equipped vehicle used to provide emergency medical assistance and transport sick or injured people.

When does an ambulance have priority?

This depends on the local traffic rules and warning signals being used. Ambulances responding to emergencies commonly use flashing lights and a siren to indicate that other road users must make way.

What should you do when an ambulance approaches?

Remain calm and make sufficient space for it to pass. Slow down or stop where necessary, but avoid sudden or dangerous manoeuvres.

Should you stop immediately when you hear an ambulance siren?

Not necessarily in your exact position. Move or stop in a way that creates a safe passage without blocking an intersection, pedestrian crossing or another part of the road needed by the ambulance.

Can an ambulance pass a red traffic light?

Emergency vehicles may be allowed to pass a red light during an urgent response under special legal conditions. The precise rules differ between countries, and the ambulance driver must still take appropriate precautions.

Can an ambulance exceed the speed limit?

Many countries permit emergency vehicles to depart from certain normal speed rules during an urgent mission, subject to safety requirements and national legislation.

Can an ambulance drive through a traffic queue?

Yes, when responding to an emergency and legally permitted to do so. Other road users should create space and keep emergency corridors or access routes clear where required.

Can you follow an ambulance through traffic?

You should not use the passage created for an ambulance as a way to bypass congestion. Maintain a safe distance and continue to obey the normal traffic rules.

Do ambulances always use their sirens?

No. The use of warning lights and sirens depends on the urgency of the mission and local regulations. An ambulance transporting a patient does not necessarily need to use emergency signals throughout the journey.

What should you do near a stationary ambulance?

Reduce speed and remain alert. Medical personnel, patients or other emergency workers may be entering the road, and the ambulance may need to move unexpectedly.

15. タクシー

タクシーは、料金を受け取って乗客を希望地点間で輸送する車両です。タクシー乗り場から乗車、路上で乗車、電話やアプリで予約する方式などがあります。

通常、専用表示、屋根灯、特別ナンバー、地域許可などで識別されます。免許、運賃、営業規則は国や都市によって異なります。

タクシー
What is a taxi?

A taxi is a vehicle used to transport passengers for payment, normally providing journeys requested by individual customers.

Where can passengers find a taxi?

Depending on the local system, taxis may be available at taxi stands, airports, railway stations, on the street or through telephone and app-based booking services.

Are taxis regulated?

Yes. Taxi services are generally subject to licensing and operating requirements, although the exact rules concerning vehicles, drivers, fares and permitted operating areas vary between jurisdictions.

16. 欧州排出ガス基準

欧州排出ガス基準(Euro基準)は、車両・エンジンの汚染物質排出上限に基づく欧州の車両分類です。Euro 4、Euro 5、Euro 6など後続基準ほど、窒素酸化物、粒子状物質、一酸化炭素、炭化水素などの上限が厳しくなりました。

車両のEuro基準は型式認証時に決まり、車種、燃料、認証時の排出法規などに左右されます。低排出ゾーンの進入条件にも使われますが、具体的規則は国・都市で異なります。

欧州排出ガス基準
What is a European emission standard?

A European emission standard, or Euro standard, classifies vehicles according to the emissions requirements they had to satisfy when approved for use in the European market.

What do Euro 4, Euro 5 and Euro 6 mean?

They are successive generations of European emission requirements. In general, a higher Euro number represents a newer and stricter emissions standard, although the exact limits differ according to vehicle and fuel type.

Which pollutants do Euro standards regulate?

Depending on the vehicle and standard, limits apply to pollutants such as nitrogen oxides, particulate matter, carbon monoxide and hydrocarbons. Newer standards also regulate additional environmental aspects.

Is the Euro standard the same as a vehicle's CO2 emissions?

No. Euro standards primarily regulate harmful air pollutants from vehicles. Carbon-dioxide emissions and fuel or energy consumption are subject to separate measurements and regulatory requirements.

How can you find a vehicle's Euro standard?

The Euro standard may appear on the vehicle registration certificate, certificate of conformity or other official vehicle documentation. Its location and format vary between countries.

Does the year of a vehicle determine its Euro standard?

The date of first registration can provide an indication, but it does not always determine the standard with certainty. The official vehicle documents or type-approval information provide the more reliable classification.

Can petrol and diesel vehicles with the same Euro number have different emission limits?

Yes. The applicable emission limits and testing requirements can differ according to the vehicle category, engine and fuel type even when vehicles belong to the same general Euro generation.

Can the Euro standard affect access to a low-emission zone?

Yes. Many low-emission zones use the vehicle's Euro standard together with factors such as fuel type and vehicle category to determine whether it may enter.

Does installing a particulate filter automatically change the Euro standard?

Not normally. The official Euro standard is linked to the vehicle's approved emissions classification. Retrofitting emission-control equipment does not necessarily result in a different official Euro classification.

What is Euro 7?

Euro 7 is the latest European emissions framework for road vehicles. It builds on earlier Euro standards and also introduces requirements covering areas such as non-exhaust particle emissions and battery durability.

17. ポットホール

ポットホールは、摩耗、天候、水、反復荷重、舗装劣化などにより路面に生じる穴・窪みです。大きさ・深さはさまざまで、凍結、豪雨、反復交通で悪化することがあります。

操舵、制動、車両安定性へ影響し、タイヤ、ホイール、サスペンションを損傷することがあります。前方路面を確認し、速度を調整し、危険な急操作を避けます。

ポットホール
What is a pothole?

A pothole is a hole or depression that develops in a road surface when the pavement becomes damaged or deteriorates.

How do potholes form?

Potholes can develop through a combination of water, temperature changes, traffic loads and deterioration of the road material. Cracks can gradually expand until pieces of the surface break away.

Why are potholes dangerous?

A pothole can cause a vehicle to change direction suddenly, lose stability or suffer tyre, wheel or suspension damage. Deep potholes can present a particularly serious hazard at higher speeds.

What should you do when you see a pothole?

Reduce speed when necessary, maintain control of the vehicle and avoid abrupt steering or braking. Only move around the pothole when this can be done safely without endangering other road users.

Should you brake while driving through a pothole?

If possible, reduce your speed before reaching the pothole. Sudden heavy braking or steering while passing over a damaged surface can make the vehicle less stable.

Are potholes particularly dangerous for motorcycles?

Yes. A pothole can disturb the steering or balance of a motorcycle and may cause the rider to lose control.

Are potholes dangerous for cyclists?

Yes. Bicycle wheels can be strongly affected by deep holes or sharp edges, particularly when the cyclist has little time or space to avoid the hazard.

Can a pothole damage a car?

Yes. Severe impacts can damage tyres, wheel rims, suspension components, steering parts or wheel alignment.

Should you swerve suddenly to avoid a pothole?

No. A sudden evasive movement may create a greater danger by bringing the vehicle into conflict with cyclists, pedestrians, oncoming traffic or vehicles in another lane.

Can a warning sign indicate potholes ahead?

Yes. Depending on the country's traffic-sign system, an uneven-road or general-danger warning sign may be used where poor road conditions create a significant hazard.

18. 通路

通路は、主に歩行者向けの比較的狭い経路で、許可されている場合はその他の道路利用者や小型車両も利用できます。市街地、農村、公園、森林、道路間などに設けられ、舗装されている場合と未舗装の場合があります。

通路は必ずしも歩道や自転車道と同じではありません。利用できる道路利用者は、その法的区分、幅、交通標識、地域規則によって決まります。

通路
What is a path?

A path is a relatively narrow route intended primarily for pedestrians and, where permitted, other road users or small vehicles.

Is a path the same as a footpath?

Not necessarily. A footpath is specifically intended for pedestrians, while a path may also permit cyclists or other users according to local rules.

Is a path the same as a cycle path?

No. A cycle path is specifically designated for bicycles and other permitted users. An ordinary path does not automatically have that legal status.

Can cyclists use a path?

This depends on the legal status, width and signs applying to the path. Some paths permit cyclists, while others are reserved for pedestrians or particular users.

Can motor vehicles use a path?

This depends on local law. Some paths prohibit motor vehicles entirely, while narrow vehicles may be permitted on other paths unless traffic signs restrict access.

Can a path be part of the public-road network?

Yes. A narrow path can legally form part of the public-road network even when it is unsuitable for ordinary cars.

Does a path need to be paved?

No. Paths can be paved, gravelled, compacted or unsurfaced depending on their location and purpose.

Can traffic signs restrict access to a path?

Yes. Signs can reserve a path for particular road users or prohibit certain vehicles, regardless of whether they could physically fit on it.

Who has priority when a path joins a larger road?

The applicable local priority rules determine who must give way. Special rules often apply when a minor path joins an ordinary road.

Can pedestrians and cyclists share a path?

Yes, where both are permitted. Faster users should adapt their speed and avoid endangering or unnecessarily obstructing pedestrians.

Can a path cross another road?

Yes. At the crossing, users must follow the applicable priority signs, traffic lights, road markings and general right-of-way rules.

Is every narrow route legally a path?

No. Its legal classification depends on the definitions and regulations of the country concerned. A narrow route might instead be a footpath, cycle path, private access road or another type of facility.

19. 粒子状物質

粒子状物質(particulate matter、PM)は、空気中に浮遊する微小な固体粒子または液滴です。道路交通では、排気ガス、ブレーキ摩耗、タイヤ摩耗、路面摩耗のほか、通過車両が巻き上げるほこりからも発生します。

粒子状物質は一般に粒径で分類されます。PM10は直径およそ10マイクロメートル以下、PM2.5はおよそ2.5マイクロメートル以下のより細かい粒子を指します。車両排出ガス基準、粒子フィルター、大気質対策などにより、これらの汚染物質への曝露低減が図られます。

粒子状物質
What are particulates?

Particulates, or particulate matter, are very small solid particles or liquid droplets suspended in the air.

What are PM10 and PM2.5?

PM10 refers to particles with a diameter of up to approximately 10 micrometres. PM2.5 refers to finer particles with a diameter of up to approximately 2.5 micrometres.

Where do traffic particulates come from?

Road traffic can produce particles through engine exhaust, brake wear, tyre wear and road-surface wear. Passing traffic can also resuspend dust already present on the road.

Are diesel vehicles a source of particulates?

Yes. Combustion in diesel engines can produce very small soot particles. Modern diesel vehicles commonly use particulate filters to capture a large proportion of these exhaust particles.

What is a particulate filter?

A particulate filter is an exhaust-treatment device designed to trap particulate matter produced by an engine. Diesel particulate filters are commonly known as DPFs.

Do petrol engines produce particulates?

Yes. Petrol engines can also produce particulate emissions, particularly certain direct-injection engines. Appropriate emission-control systems may therefore include particulate filters.

Do electric vehicles produce particulates?

Fully electric vehicles produce no exhaust particulates from a combustion engine, but particles can still result from tyre wear, road wear and braking.

Are brake and tyre particles regulated?

Vehicle-emission regulation is increasingly addressing non-exhaust emissions. The European Euro 7 framework includes requirements concerning brake-particle emissions and tyre abrasion.

Is particulate matter the same as CO2?

No. Particulate matter consists of tiny airborne particles, while carbon dioxide is a gas. They are different types of vehicle emissions and are regulated for different environmental reasons.

How can vehicle particulate emissions be reduced?

Measures include effective particulate filters, cleaner vehicle technologies, correctly maintained emission-control systems and reductions in brake, tyre and road-wear emissions.

20. 大気汚染

大気汚染は、人の健康、環境、生態系へ悪影響を与える濃度で、気体、粒子、その他の物質が空気中に存在する状態です。道路交通は排気ガスに加え、ブレーキ摩耗、タイヤ摩耗、道路粉じんなど非排気由来の排出によっても大気汚染へ寄与します。

交通に関連する主な汚染物質には、窒素酸化物、粒子状物質、一酸化炭素、揮発性有機化合物があります。車両から直接排出されるものもあれば、大気中の化学反応で生成されるものもあります。車両排出ガス基準、よりクリーンな技術、交通管理対策などが排出削減に使われます。

大気汚染
What is air pollution?

Air pollution is contamination of the air by gases, particles or other substances that can adversely affect human health, the environment or ecosystems.

How does road traffic cause air pollution?

Vehicles produce pollutants through fuel combustion, exhaust systems, brake wear, tyre wear and road-surface interaction. Moving traffic can also resuspend dust already present on the road.

Which air pollutants are associated with road traffic?

Important traffic-related pollutants include nitrogen oxides, particulate matter, carbon monoxide and volatile organic compounds. Their relative importance depends on the vehicle, fuel and driving conditions.

What is nitrogen dioxide?

Nitrogen dioxide (NO2) is an air pollutant associated particularly with combustion processes and road traffic. High concentrations are commonly found near busy roads and densely trafficked urban areas.

What is particulate matter?

Particulate matter consists of tiny solid particles or liquid droplets suspended in the air. Road traffic can produce particles from exhaust, brakes, tyres and road surfaces.

Is CO2 the same as ordinary air pollution?

No. Carbon dioxide is primarily regulated as a greenhouse gas because of its contribution to climate change. Local air-quality pollution generally focuses on substances such as nitrogen dioxide, particulate matter, ozone and other pollutants that directly affect air quality and health.

Do electric vehicles cause air pollution?

Fully electric vehicles produce no combustion-engine exhaust emissions while driving, but they can still contribute to non-exhaust particulate emissions through tyres, brakes and road wear.

Can air pollution be worse near busy roads?

Yes. Concentrations of traffic-related pollutants can be higher close to heavily trafficked roads because many emissions occur close to ground level and near where people live and travel.

What is a low-emission zone?

A low-emission zone is an area where access by more polluting vehicles is restricted in order to reduce traffic-related air pollution. Access criteria may depend on factors such as fuel type, vehicle category and emission standard.

How can traffic-related air pollution be reduced?

Measures include cleaner vehicles, stricter emission standards, effective emission-control equipment, low-emission zones, public transport, cycling and walking, as well as traffic-management measures that reduce unnecessary congestion and emissions.

21. ラッシュアワー

ラッシュアワーは、多くの人が通勤、通学、その他の定期的な移動を行うため、道路や公共交通網の需要が特に高くなる時間帯です。通常、平日の朝と夕方から夜にかけて発生します。

ラッシュ時には渋滞、低速走行、移動時間の増加、頻繁な停止が生じます。運転者は安全な車間距離を保ち、焦らず、交通状況の変化を予測し、臨時または動的な交通管理措置に従います。

ラッシュアワー
What is rush hour?

Rush hour is a period when unusually large numbers of people travel at the same time, resulting in increased traffic and often congestion.

When does rush hour occur?

Rush hour commonly occurs during the morning and late afternoon or evening on working days, but the exact times vary according to the city, road and local travel patterns.

Does rush hour always last one hour?

No. The term does not mean that congestion lasts exactly one hour. In busy urban areas, peak traffic conditions may continue for several hours.

Why does traffic become congested during rush hour?

Congestion develops when traffic demand approaches or exceeds the available road capacity. Intersections, merging traffic, collisions, roadworks and weather can make the congestion worse.

Should you increase your following distance in rush-hour traffic?

Yes. Leave sufficient distance to react to sudden braking and frequent changes in traffic speed. Avoid following another vehicle too closely even when traffic is moving slowly.

Should you frequently change lanes during congestion?

Unnecessary lane changes can create additional conflicts and may not significantly reduce journey time. Choose an appropriate lane, observe surrounding traffic and change lane only when it can be done safely.

Can speed limits change during rush hour?

Yes. Roads equipped with variable traffic management may display lower speed limits during congestion. Drivers must follow the speed limit currently indicated.

What is a rush-hour lane?

A rush-hour lane is an additional traffic lane that can be opened during busy periods to increase road capacity. It may use a lane or shoulder that is closed to normal traffic at other times.

Can you use a rush-hour lane whenever traffic is congested?

No. Such a lane may only be used when traffic signals or signs indicate that it is open. Never assume that congestion alone permits its use.

How can you prepare for a journey during rush hour?

Check current traffic conditions and expected journey times, allow additional travel time and consider an alternative route, departure time or mode of transport where appropriate.

22. 交通法規

交通法規は、人々が公道をどのように利用するかを定める法律や交通規則の体系です。運転者、自転車利用者、歩行者、その他の道路利用者に適用され、優先、速度、追い越し、駐車、信号機、道路標識、路面標示などを扱います。

交通法規は国によって、場合によっては地域によって異なります。道路利用者は、母国の規則と異なる場合でも移動先で適用される規則を知り、従うことが求められます。

What is a road code?

A road code is the body of traffic rules and regulations governing how road users must behave on public roads.

What does a road code regulate?

A road code can regulate subjects such as priority, speed, overtaking, turning, parking, traffic signals, road signs and road markings, as well as the responsibilities of different road users.

Are road codes the same in every country?

No. Although many traffic rules and signs are similar internationally, each country establishes its own traffic legislation and may apply different rules, signs, speed limits and requirements.

23. 道路側溝

道路側溝は、道路や街路の端に沿って設けられ、雨水を集めて排水口などへ流す細い水路です。通常、車道と縁石の間にあり、コンクリート、舗石、路面の一部などで形成されます。

道路側溝は主に排水設備であり、交通車線ではありません。水、破片、排水口、凹凸などがある場合があるため、道路利用者は側溝付近で注意します。

道路側溝
What is a street gutter?

A street gutter is a drainage channel along the edge of a road that collects rainwater and directs it toward drains or another drainage system.

Is a street gutter a traffic lane?

Normally, no. A gutter is primarily part of the road's drainage system and is not intended to function as a normal traffic lane.

Why should cyclists take care near street gutters?

Gutters may contain water, leaves, debris, drain covers or uneven surfaces, which can reduce grip or make cycling less stable.

24. カーゴバイク

カーゴバイク
What is a cargo bike?

A cargo bike is a bicycle designed to carry goods, children or larger loads than a conventional bicycle.

What types of cargo bikes are there?

Common designs include two-wheel box bikes, three-wheel cargo bikes and longtail bicycles with an extended rear carrying area.

Can a cargo bike be electric?

Yes. Many cargo bikes use electric pedal assistance to make it easier to move heavier loads or travel longer distances.

Is an electric cargo bike still a bicycle?

It can be. If the electrical assistance remains within the applicable power and assistance-speed limits, the vehicle may remain legally classified as a bicycle. More powerful or faster models may belong to another category.

Can a cargo bike carry children?

Yes, when it is designed and equipped for passenger transport. Children should use the seats, restraints, foot protection or other safety equipment provided by the manufacturer and required by local law.

Can a cargo bike carry goods?

Yes. Transporting goods is one of its main purposes. Loads must be securely positioned and must not make the bicycle unstable, obstruct the rider's view or exceed applicable dimensional or weight limits.

Can a cargo bike use a cycle path?

This depends on its dimensions and legal classification. Ordinary-sized cargo bicycles generally follow bicycle rules, while unusually wide models may be excluded from certain cycle facilities.

Does a cargo bike need a driving licence?

Normally not when it remains legally classified as an ordinary bicycle or electrically assisted bicycle. Faster or more powerful vehicles may be subject to different licensing requirements.

Is a helmet compulsory on a cargo bike?

This depends on the country's bicycle rules and the vehicle's classification. A model legally classified as a faster motorised vehicle may have different helmet requirements from an ordinary cargo bicycle.

Should you ride differently when a cargo bike is heavily loaded?

Yes. Additional weight can affect acceleration, braking, steering and stability. Reduce speed where necessary, allow greater stopping distance and take particular care when turning.

Can a cargo bike tow a trailer?

Yes, where permitted. The bicycle, trailer and total load must comply with the applicable dimensional, mass, braking and passenger-transport requirements.

Why should drivers take care around cargo bikes?

Cargo bikes can be longer, wider and heavier than ordinary bicycles and may need additional space when turning or stopping. Drivers should leave sufficient passing distance and avoid cutting across their path.

What is a forestry vehicle?

A forestry vehicle is a vehicle designed or adapted for forestry work, such as pulling machinery, carrying equipment, transporting timber or working on forest land.

Is a forestry vehicle always a tractor?

No. Forestry vehicles can include tractors, specialised self-propelled machines, trailers and other equipment. Their legal classification depends on their design and use.

What is a forestry tractor?

A forestry tractor is a powered vehicle primarily designed to pull, push, carry or operate equipment or trailers used for forestry work.

Can forestry vehicles travel on public roads?

Yes, when legally permitted and properly equipped. Registration, insurance, lighting, dimensions, speed and driving-licence requirements may apply before a forestry vehicle can use public roads.

Do you need a special driving licence for a forestry vehicle?

This depends on the vehicle classification, mass and country. Some countries have special agricultural or forestry vehicle licence categories, while other machines require ordinary car or heavy-vehicle licences.

Do forestry vehicles have special speed limits?

They may. The permitted speed can depend on the vehicle's construction speed, mass, road type and local traffic rules. Posted speed limits must also be respected.

Can forestry vehicles use motorways?

This depends on the country and vehicle classification. Agricultural and forestry vehicles are often restricted from high-speed roads, particularly when their construction speed is unsuitable for motorway traffic.

Why should drivers take care when passing a forestry vehicle?

Forestry vehicles can be large, slow, wide or equipped with projecting machinery. Reduce speed where necessary and overtake only when there is sufficient visibility and space.

Can a forestry vehicle tow a trailer?

Yes, where the vehicle is designed and approved to do so. Forestry tractors commonly tow trailers carrying timber, machinery or other forestry materials.

Can forestry equipment extend beyond the normal width of the vehicle?

Some machinery or loads may make a forestry vehicle unusually wide or long. Where legal limits are exceeded, special markings, lighting, permits or escort arrangements may be required under local law.
