道路標識日本

わかりやすい説明と視覚的な例を使った図解付きの本で、交通ルールをシンプルかつ楽しく学べます。


51. 停車禁止

停車禁止は、乗客の乗降や荷物の積み下ろしのための短時間停止も含め、指定場所で任意に停止してはいけないことを意味します。駐車禁止より厳しい規制です。

標識、路面表示、地域規則で示されます。交通状況、緊急事態、法的義務によって停止を強制される場合を除き、停車可能な場所まで進む必要があります。

停車禁止
What does a no stopping restriction mean?

It means that a driver may not voluntarily stop the vehicle in the restricted area. The prohibition normally includes stopping to pick up or drop off passengers or to load or unload goods.

What is the difference between no stopping and no parking?

No stopping is the stricter restriction. A no-parking rule may still allow a brief stop for activities such as picking up passengers or loading goods, while a no-stopping rule prohibits these voluntary stops as well.

Can you stop in a no-stopping area during an emergency?

A driver may have to stop because of an emergency, traffic conditions, a red light, police instructions or another situation outside the driver's control. Such compulsory stops are generally different from voluntarily stopping the vehicle.

52. 障害者用駐車

障害者用駐車は、適用要件を満たす障害者のために確保された駐車枠や駐車特例です。通常、国際的な車いす記号で示され、施設へ容易にアクセスできる位置に配置されます。

利用には一般に有効な障害者駐車許可証やカードが必要です。許可証は通常、特定車両ではなく対象者に属し、その人が運転または同乗している場合にのみ使用できます。

障害者用駐車
Who may use a disabled parking space?

Disabled parking spaces are intended for eligible people who hold a valid disabled parking permit or card. The exact eligibility requirements and permit system depend on the country.

Can someone use a disabled parking permit when the holder is not present?

Generally no. Disabled parking permits are normally personal and may only be used when the permit holder is driving or travelling in the vehicle.

Does a disabled parking permit always provide free parking?

No. A permit may provide access to reserved spaces or exemptions from certain parking restrictions, but rules concerning parking charges and time limits vary between countries and local authorities.

53. 交通管理

交通管理は、道路利用者を組織的に制御、規制、誘導し、安全、交通流、道路の効率的利用を改善することです。信号、標識、路面表示、車線規制、可変速度制限、迂回、係員の指示などがあります。

交通管理は恒久的または一時的です。工事、渋滞、事故、イベントなどでは一時措置が導入されます。通常の道路配置と異なっていても、その場所の標識、信号、指示に従います。

交通管理
What is traffic management?

Traffic management is the organised control and guidance of traffic using signs, signals, road markings, lane controls, speed restrictions, diversions and other measures.

Why is traffic management used?

Traffic management is used to improve safety, control traffic flow and reduce disruption. It can also protect road workers, pedestrians, cyclists and emergency services.

How can traffic be managed?

Common methods include traffic lights, road signs, road markings, variable-message signs, lane-control signals, temporary barriers, speed restrictions and diversions. Authorised persons may also direct traffic.

Can traffic management change the normal speed limit?

Yes. Temporary or variable speed-limit signs may impose a different maximum speed because of congestion, roadworks, weather, incidents or other conditions. Drivers must follow the limit currently displayed.

Can traffic management change which lanes you may use?

Yes. Lane-control signals, temporary signs or road markings may close lanes, move traffic into different lanes or require drivers to change lane. Follow the current signs and markings rather than the normal road layout.

What should you do when a traffic lane is closed?

Move into an open lane safely and in good time, following any arrows, signs and local merging rules. Never continue along a lane that is clearly indicated as closed.

Can temporary traffic signs be compulsory?

Yes. Properly authorised temporary signs used for roadworks, incidents or other traffic-management measures must be obeyed in the same way as other official traffic signs.

What should you do when an authorised person directs traffic?

Follow the directions of the authorised person. In many countries, these directions take precedence over traffic lights, road signs or the normal traffic rules.

How is traffic managed around roadworks?

Roadworks may use temporary speed limits, lane closures, barriers, temporary markings, traffic lights and diversions. Road users should reduce speed where necessary and carefully follow the temporary route.

Does traffic management also protect pedestrians and cyclists?

Yes. Temporary or permanent traffic arrangements should account for pedestrians and cyclists as well as motor vehicles. They may be provided with separate routes, crossings, signals or diversions where necessary.

54. 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.

55. Uターン

Uターンは、車両が向きを変え、来た方向と反対へ走行する運転操作です。通常は車道の一部を横切り、反対方向の交通へ入り直します。

周囲の交通、歩行者、自転車を確認し、必要な合図を行い、十分な視界と空間があることを確認して安全に行います。標識や特定道路ではUターンが禁止されることがあります。

Uターン
What is a U-turn?

A U-turn is a manoeuvre used to reverse a vehicle's direction so that it continues along the road in the opposite direction.

What should you check before making a U-turn?

Check traffic in all relevant directions, mirrors and blind spots, and look for pedestrians, cyclists and other road users. Make sure there is sufficient visibility and space and that the manoeuvre is permitted.

Can you make a U-turn anywhere?

No. U-turns may be prohibited by traffic signs or road rules and should never be attempted where visibility, road layout or traffic conditions make the manoeuvre unsafe.

56. 無規制交差点

無規制交差点は、特定の進入方向に対する優先が信号、交通整理員、優先指定標識で明確に定められていない交差点です。その国の既定交通規則により誰が優先か判断します。

国によって右方優先、左方優先、その他の既定優先規則があります。慎重に接近して全方向を確認し、道路幅が広い、交通量が多いという理由だけで優先と決めつけてはいけません。

無規制交差点
What is an uncontrolled crossroad?

An uncontrolled crossroad is an intersection where priority is not specifically assigned by traffic lights, an authorised person or priority signs. Drivers must use the default priority rules of the country.

Who has priority at an uncontrolled crossroad?

This depends on the local traffic law. Some countries use priority from the right, while others use different rules. Drivers should know the default intersection rule of the country in which they are driving.

Does the wider road automatically have priority?

Not necessarily. The width, surface or amount of traffic on a road does not by itself determine priority unless local law specifically provides otherwise.

Should you slow down at an uncontrolled crossroad?

Yes. Approach at a speed that allows you to observe approaching traffic, determine who has priority and stop safely if necessary.

Do cyclists have to follow the priority rules at an uncontrolled crossroad?

Yes. Cyclists generally follow the applicable intersection priority rules unless a specific cycle facility, sign or local rule provides otherwise.

Does driving straight ahead automatically give you priority?

No. Continuing straight ahead does not automatically give priority over traffic approaching on another road. The applicable priority rules must still be followed.

Does turning right or left change the priority rules?

Turning may create additional obligations, particularly towards pedestrians, cyclists or opposing traffic. Drivers must follow both the intersection priority rule and the rules governing the intended turn.

What if two vehicles reach an uncontrolled crossroad at the same time?

Apply the country's default priority rule. Do not rely simply on which vehicle appears to have arrived first unless local law specifically uses that rule.

What if the traffic lights at an intersection are not working?

The intersection is not necessarily completely uncontrolled. Priority signs, road markings and default priority rules may still determine who must give way. Drivers should approach with particular caution.

What should you do if you are unsure who has priority?

Reduce speed and be prepared to stop. Never force your way through an intersection simply because the priority situation is unclear.

57. 路面

路面状態警戒は、前方路面が凹凸、破損、不良状態で、車両の安定性、操舵、制動へ影響する可能性を示します。段差、窪み、穴、舗装破損などが含まれます。

必要に応じて減速し、安全な車間距離を保ち、不整路面上では急な操舵や制動を避けます。標識の意味や形は国によって異なるため、現地の交通標識と規則に従います。

路面
What does a road surface warning mean?

A road surface warning indicates that the surface ahead may be uneven, damaged or otherwise capable of affecting the safe movement of vehicles.

What kinds of road defects can the warning indicate?

Depending on the country, it may warn of bumps, depressions, potholes, broken pavement, uneven repairs or other surface irregularities.

What should you do when you see a road surface warning?

Reduce speed where necessary, increase your awareness of the road ahead and be prepared for changes in the vehicle's stability or direction.

Does a road surface warning impose a specific speed limit?

Not normally. A warning sign alerts drivers to a hazard rather than establishing a numerical speed limit. A separate speed-limit sign may be used where a particular maximum speed is required.

Should you brake before reaching an uneven road surface?

Where slowing is necessary, it is generally safer to reduce speed before reaching the irregular surface rather than braking sharply while travelling over it.

Why can an uneven road surface be dangerous?

A severe surface irregularity can affect tyre contact, steering, braking and vehicle stability. It can also damage tyres, wheels or suspension components.

Are motorcycles and bicycles particularly affected by uneven surfaces?

Yes. Two-wheeled vehicles can be particularly sensitive to potholes, ridges and other irregularities because these hazards may disturb their balance or alter their direction suddenly.

Is an uneven-road warning the same as a slippery-road warning?

No. An uneven-road warning concerns the physical condition or shape of the road surface. A slippery-road warning concerns reduced tyre grip caused by the surface or conditions such as water, ice, mud or other substances.

Can the warning apply over a longer section of road?

Yes. A supplementary sign may indicate the distance to the hazard or the length of the affected section, depending on the country's traffic-sign system.

Should you increase your following distance on a poor road surface?

Yes, when conditions require it. Additional distance provides more time to react if the vehicle ahead slows suddenly to avoid a pothole or other surface defect.

58. 仮運転免許

仮運転免許は、本免許取得前に学習者が公道で運転練習することを許可する免許です。国によって条件は異なり、認定同乗者の必要性、運転できる車両、運転できる場所や時間、有効期間などが定められます。通常、本免許より厳しい規則が適用され、運転技術を学び実地経験を積むためのものです。

仮運転免許
What is a provisional driving licence?

A provisional driving licence allows a learner driver to practise driving under specified conditions before obtaining a full driving licence.

Can you drive alone with a provisional licence?

This depends on the type of provisional licence and local rules. Some licences require an approved supervisor, while others allow the learner to practise alone after completing specified training.

How long is a provisional licence valid?

The validity period varies between countries and licence types. If it expires before the learner passes the practical exam, additional conditions may apply before another provisional licence can be obtained.

Can you drive abroad with a provisional licence?

Often not. A provisional licence may be valid only in the country that issued it. Learners should check the applicable rules before attempting to drive abroad.

Are there restrictions on when a learner may drive?

Yes, in some countries. Provisional licences may include restrictions on night driving, passengers, trailers, vehicle types or certain roads.

Do you need to display a learner sign?

Many countries require a learner vehicle to display an L plate or another learner-driver sign. The design and conditions vary by country.

59. 非常口

非常口は、火災、煙、その他の重大事故時に道路利用者がトンネルなど閉鎖型交通施設から避難できるよう示された避難経路です。非常口は直近の危険から隔離されたより安全な区域へつながります。

避難が必要な場合、乗員は車両から離れ、非常口標識と指示に従います。危険から離れ、トンネル内に留まったり車両へ戻ったりしてはいけません。

非常口
What is an emergency exit in a road tunnel?

An emergency exit is a designated escape route that allows people to leave the traffic area of a tunnel and reach a safer location during an emergency.

When should you use a tunnel emergency exit?

Use an emergency exit when evacuation is necessary because of fire, smoke or another serious danger, or when instructed to evacuate by tunnel personnel or emergency services.

Should you take your vehicle through an emergency exit?

No. Tunnel emergency exits are intended for people evacuating on foot. Leave the vehicle when necessary and follow the marked escape route towards safety.

60. 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。

市街地境界
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.

61. クラクション

クラクションは、危険を警告したり、安全上必要な場合に他の道路利用者の注意を引くための音響装置です。多くの自動車ではハンドルから操作する電気式ホーンが装備されています。交通法規では、特に市街地や住宅地で不必要・過度な使用が制限されるのが一般的です。そのためクラクションはいら立ちを表したり挨拶するためではなく、警告装置として使用します。

クラクション
What is a car horn?

A car horn is a sound-producing warning device used to alert other road users when their attention is needed for safety.

When should you use the horn?

The horn should generally be used when a sound warning is necessary to help prevent danger or an accident. The exact circumstances in which horn use is permitted depend on local traffic laws.

Can you use the horn to show annoyance?

Generally, no. A horn is intended as a safety warning device, and unnecessary or excessive use may be prohibited by local traffic rules.

Can you use the horn at night?

Rules for using the horn at night vary between countries. Some traffic laws restrict sound signals at night and require drivers to use their lights instead, except when there is immediate danger.

Can a vehicle horn be modified?

Vehicle horns may have to meet technical requirements for their sound and operation. Horns that imitate emergency-service sirens or otherwise fail applicable vehicle standards may be prohibited.

Is the horn checked during a vehicle inspection?

In countries with periodic technical inspections, the operation and condition of the horn may be checked as part of the vehicle's safety equipment.

62. ナンバープレート

ナンバープレート(登録番号標または車両番号標)は、登録当局から車両へ割り当てられた固有の登録識別番号を表示するプレートです。車両登録、交通取締、税、保険、駐車管理などで車両を識別するために使われます。

外観、形式、取付位置、必要枚数は国や車種で異なります。必要なプレートを正しく取り付け、はっきり見え、読み取れる状態に保ち、紛失、盗難、破損、交換時には現地規則に従います。

ナンバープレート
What is a licence plate?

A licence plate is a plate displaying the registration identifier assigned to a vehicle. It allows authorities and other authorised systems to identify the vehicle's registration.

Is a licence plate the same as a registration plate?

Yes. Licence plate, registration plate and number plate are different terms commonly used for the plate displaying a vehicle's official registration number.

Does every vehicle need a licence plate?

Most motor vehicles used on public roads must display one or more registration plates, but requirements differ for motorcycles, trailers, agricultural vehicles and other special vehicle categories.

Do vehicles need both front and rear licence plates?

This depends on the country and vehicle type. Cars commonly require front and rear plates, while motorcycles and certain other vehicles may require only a rear plate.

Must a licence plate remain visible?

Yes. A required registration plate must normally remain clearly visible and readable. It should not be hidden by luggage, dirt, accessories or other objects.

Can you modify a licence plate?

Generally no. Changing the characters, colours, dimensions or appearance of an official plate may make it invalid or illegal. Plates and authorised reproductions must comply with local specifications.

What should you do if a licence plate is lost or stolen?

Follow the local reporting and replacement procedure. Many countries require the loss or theft to be reported to the police or vehicle-registration authority before a replacement plate can be issued.

Can you drive with a damaged licence plate?

A plate must remain legible and compliant with local requirements. If damage prevents it from being read or makes it invalid, it should be replaced according to the local registration procedure.

Can a licence plate be personalised?

Some countries allow motorists to request a personalised registration combination. The available characters, formats and prohibited combinations are determined by the registration authority.

Does a licence plate stay with the vehicle when it is sold?

This varies between countries. In some systems the plate remains with the vehicle, while in others it remains associated with the registered holder and may be retained or returned when the vehicle is sold.

63. 充電ステーション

充電ステーションは、電気自動車またはプラグインハイブリッド車のバッテリーを電源へ接続して充電できる1基以上の充電器を備えた場所です。公道沿い、駐車場、サービスエリア、私有地などに設置されます。

充電スペースは充電中の車両専用の場合があり、駐車制限、時間制限、料金などの条件が適用されます。現地の標識、駐車規則、充電設備の指示に従います。

充電ステーション
What is a charging station?

A charging station is a location where electric vehicles can be connected to an electricity supply to recharge their batteries. A station may contain one or several individual charging points.

Who can use an electric-vehicle charging station?

Charging stations are intended for vehicles that can be externally charged, such as battery-electric vehicles and plug-in hybrid vehicles. The exact vehicle categories permitted may be indicated by local signs or operator conditions.

Is a charging space an ordinary parking space?

Not necessarily. A space beside a charger may be reserved for electric vehicles or vehicles that are charging. Drivers must check the signs and markings before parking there.

Can a petrol or diesel vehicle park at a charging station?

Not where the parking space is officially reserved for electric vehicles. An ordinary parking space located near a charger may be different, so the applicable signs and markings determine who may park there.

Can an electric vehicle park at a charging point without charging?

This depends on the local traffic and parking rules. Many charging spaces require the vehicle to be connected to the charger, even if the vehicle itself is electric.

Do you have to pay to use a charging station?

Charging may be free or subject to payment. The price and payment method are determined by the charging operator, while separate parking charges may also apply.

Can a charging station have a maximum parking time?

Yes. Traffic signs, parking regulations or charging conditions may establish a maximum duration to encourage drivers to move their vehicles and make the charger available to others.

Must you move the vehicle when charging is finished?

Follow the local parking rules and charging conditions. Some locations require vehicles to leave after charging or impose additional fees or time limits when the charging session has ended.

Does using a charger override ordinary parking restrictions?

No. A charging station does not allow a driver to ignore no-parking rules, reserved spaces, time limits or other traffic regulations. The vehicle must still be legally parked.

Are all charging stations equally fast?

No. Charging stations can provide different charging powers. Some are intended for longer parking periods, while high-power chargers can recharge compatible vehicles much more quickly.

64. 一般危険

一般危険警戒標識は、より具体的な警戒標識で表せない前方の危険を知らせます。補助標識、文字、記号などで具体的な危険内容が示される場合があります。

運転者は注意を高め、前方を確認し、危険と周囲の状況に合わせて速度を調整します。標識の形や危険の示し方は国によって異なるため、現地の交通標識と規則に従います。

一般危険
What does a general danger warning sign mean?

A general danger warning sign indicates that there is a hazard ahead that is not represented by a more specific warning sign in the local traffic-sign system.

What kind of danger can the sign indicate?

It can be used for unusual or uncommon hazards for which no dedicated warning symbol exists. The nature of the danger may be explained by an additional panel, symbol or message.

How can you know what the danger is?

Look for a supplementary panel, text or symbol accompanying the warning sign. It may describe the hazard or provide information needed to understand the warning.

What should you do when you see a general danger warning sign?

Increase your attention, observe the road and surroundings carefully and adapt your speed where necessary so that you can respond safely to the hazard.

Does the sign impose a specific speed limit?

Not normally. A warning sign alerts road users to danger rather than establishing a numerical speed limit. A separate speed-limit sign may be provided where a specific maximum speed is required.

Why is a general warning sign used instead of a specific warning sign?

It is used when the traffic-sign system does not contain a specific symbol that accurately represents the particular hazard.

Can the danger be temporary?

Yes. A general warning sign may be used for either a temporary or continuing hazard, depending on local signing rules and the circumstances.

Can a supplementary panel indicate the distance to the danger?

Yes. Depending on the country's traffic-sign system, an additional panel may indicate the distance to the hazard, the length of the dangerous section or other useful information.

Does a general danger sign give anyone priority?

No. A danger warning sign does not by itself change the priority rules. Drivers must continue to follow traffic lights, priority signs and the normal right-of-way rules.

Does the warning end immediately after the sign?

Not necessarily. The sign normally warns of a hazard ahead of the sign, and the dangerous situation may extend over a section of road. Supplementary information may indicate its location or length.

65. 歩行者

歩行者は、道路、街路、通路、公共空間を徒歩で移動する人です。現地法により、自転車、車いす、ベビーカーなどの小型器具を押している人も歩行者として扱われる場合があります。

通常、利用可能な歩道、歩行者通路、歩行者区域を使用します。適切な施設がない場所で道路を横断・歩行する場合は、横断規則、信号、その他の現地交通規則に従います。

What is a pedestrian?

A pedestrian is primarily a person travelling on foot. Local traffic laws may also treat people pushing bicycles, wheelchairs, prams or certain other devices as pedestrians.

Where should pedestrians normally walk?

Pedestrians should normally use pavements, sidewalks, footpaths or other areas provided for pedestrians. Where these are unavailable, local rules determine where pedestrians may walk on or beside the road.

Which side of the road should pedestrians walk on when there is no pavement?

This depends on the country's traffic rules. Many countries require or recommend pedestrians to face approaching traffic, but the exact rule varies.

Where should pedestrians cross a road?

Use a pedestrian crossing, traffic-light-controlled crossing or other designated crossing where required or reasonably available. Where crossing elsewhere is permitted, choose a location with good visibility and cross carefully.

Do pedestrians always have priority at a pedestrian crossing?

The exact priority rule varies between countries. Drivers are commonly required to give way to pedestrians using or entering designated crossings, but pedestrians must still obey traffic lights and avoid entering the road dangerously.

Must pedestrians obey traffic lights?

Yes. Where pedestrian signals are provided, pedestrians must follow their indications and should not enter the roadway while the signal prohibits crossing.

Is someone pushing a bicycle a pedestrian?

In many traffic systems, a person who dismounts and walks beside a bicycle is treated as a pedestrian. The precise legal classification depends on local law.

Can pedestrians use a cycle path?

This depends on the road layout and local rules. Pedestrians may sometimes use a cycle path when no suitable pedestrian facility is available, but they must not unnecessarily obstruct cyclists or other authorised users.

Do turning vehicles have to watch for pedestrians?

Yes. Drivers turning into another road must watch carefully for pedestrians crossing the road they are entering and give way where required by local traffic law.

What should pedestrians do before crossing a road?

Check carefully for approaching traffic from all relevant directions, make sure there is sufficient time and distance to cross safely, and continue to observe traffic while crossing.

66. 自転車利用者

自転車利用者は、自転車に乗り操作する人です。多くの国で自転車は法律上車両として扱われるため、自転車利用者は一般運転者と共通する多くの交通規則に加え、自転車専用規則にも従います。

必要な場合は指定自転車施設を利用し、標識・信号に従い、予測可能で安全な走行を心掛けます。道路上の位置、優先、装備、通行可能区域などは国によって異なります。

What is a cyclist?

A cyclist is a person who rides and controls a bicycle.

Is a cyclist considered a road user?

Yes. Cyclists are road users and must follow the traffic rules, signs and signals that apply to them.

Where should cyclists ride?

This depends on local rules. Cyclists may be required to use a cycle path or designated cycling facility, while in other situations they may ride on the carriageway.

67. モペッド

モペッドは通常2輪または3輪の軽量動力車で、出力、排気量、設計最高速度などが法律で制限されています。自転車とオートバイの中間的な法的カテゴリーですが、分類は国によって異なります。

最低年齢、運転免許、ヘルメット、登録、保険、最高速度、自転車道や車道の利用など特別規則が適用される場合があります。その国の分類と交通規則に従います。

モペッド
What is a moped?

A moped is a lightweight motor vehicle whose engine power, capacity or maximum design speed is restricted by law. The precise technical definition differs between countries.

Is a moped the same as a motorcycle?

No. Mopeds normally have lower maximum speeds and power than motorcycles and are classified separately under traffic and licensing laws.

Is an electric moped still a moped?

Yes, potentially. A vehicle can be legally classified as a moped whether its motor is electric or uses an internal-combustion engine. Classification depends on factors such as design speed and power.

Do you need a driving licence for a moped?

This depends on the country and moped category. Some low-speed mopeds may be ridden without a licence, while faster mopeds commonly require a dedicated moped licence or another qualifying driving licence.

Do moped riders have to wear a helmet?

Helmet requirements vary between countries, but an approved protective helmet is compulsory for moped riders in many jurisdictions. Passengers may also be required to wear one.

Can a moped use a cycle path?

This depends on the moped category, road speed limit and local signs. Some low-speed mopeds may be required to use cycle paths, while faster mopeds may be required or permitted to use the roadway.

Can a moped carry a passenger?

Only where the vehicle is designed and legally approved to carry a passenger and the rider satisfies any minimum-age or licensing requirements.

Does a moped need a licence plate?

Many countries require mopeds to be registered and display a registration plate. Requirements vary according to vehicle category and national law.

Does a moped need insurance?

Compulsory third-party liability insurance is required for mopeds in many countries. The exact insurance requirements depend on the vehicle classification and national legislation.

Can a moped use a motorway?

Mopeds are generally prohibited from motorways and other high-speed controlled-access roads because their maximum design speed is too low and the road may specifically exclude them.

68. オートバイ

オートバイは、側車の有無にかかわらず2輪の動力車です。道路走行、レクリエーション、ツーリングなどのため多様な種類・大きさがあります。

運転者は車両を完全に制御し、交通規則に従い、適切な保護装備を使用する必要があります。免許、ヘルメット、装備、道路利用要件は国によって異なります。

What is a motorcycle?

A motorcycle is a powered two-wheeled vehicle, which may also be equipped with a sidecar.

Is a motorcycle the same as a moped?

No. Traffic laws generally distinguish motorcycles from mopeds according to technical characteristics such as power, engine capacity or maximum speed.

What protective equipment should a motorcyclist use?

Motorcyclists should use an approved helmet and suitable protective clothing. The exact mandatory equipment depends on the country's traffic laws.

69. 乗用車

乗用車は、主に道路上で少人数の人と荷物を運ぶための自動車です。ガソリン、ディーゼル、電気、水素、複数エネルギーの組み合わせで動力を得ます。

運転免許、登録、保険、技術状態、シートベルト、乗員安全の要件に従う必要があります。速度、装備、道路進入などは国によって異なるため、現地の交通標識と規則に従います。

What is a car?

A car is a motor vehicle primarily designed to carry a relatively small number of passengers and their luggage on roads.

Is a car the same as a motor vehicle?

No. A car is a type of motor vehicle. The broader category of motor vehicles can also include motorcycles, buses, trucks, mopeds and other powered vehicles, depending on local legal definitions.

Do you need a driving licence to drive a car?

Yes. A driver must normally hold a valid driving licence for the vehicle category concerned. The licence categories and minimum ages vary between countries.

Does a car need to be registered?

Yes, normally. Cars used on public roads generally have to be registered with the competent authority and display the required registration plate or plates.

Does a car need insurance?

Most countries require at least third-party liability insurance before a car may be used on public roads. Additional insurance may be optional.

Must people in a car wear seat belts?

Where seat belts are fitted, drivers and passengers are generally required to wear them correctly. Exact requirements and exemptions vary between countries.

Do children need a special restraint in a car?

Yes, in many countries. Children below specified age, height or weight thresholds must be transported in an appropriate approved child-restraint system.

How many passengers can a car carry?

A car must not carry more people than it is designed and legally approved to transport. Passengers should use the designated seating positions and required restraint systems.

Can a car tow a trailer?

Yes, if the vehicle and licence permit it. Maximum trailer masses, combination masses and licence requirements depend on the vehicle and local regulations.

Can every car use a motorway?

Most ordinary cars can use motorways, but they must satisfy the applicable vehicle, speed and access requirements. Certain unusually slow or restricted vehicles may be prohibited.

70. トラック

トラックは主に貨物輸送用に設計された自動車です。小型配送車から長距離輸送用の大型貨物車・連結車まであります。

一般に乗用車より大きく重く、取り回しが遅いため、旋回・制動により大きな空間が必要で、死角も広くなります。重量や国に応じて速度、車線利用、追い越し、進入に特別規則が適用されます。

What is a truck?

A truck is a motor vehicle designed primarily for transporting goods.

Are all trucks considered heavy goods vehicles?

No. Trucks can include lighter goods vehicles as well as heavy trucks. Traffic laws often apply different rules according to the vehicle's maximum authorised mass.

Why should other road users take extra care around trucks?

Trucks may have larger blind spots, longer stopping distances and wider turning paths than smaller vehicles, so other road users should avoid remaining unnecessarily close beside or in front of them.

71. バス

バスは、公共交通、スクール輸送、私的輸送などで多数の乗客を道路上で運ぶための自動車です。乗用車より乗車定員が多く、座席のみ、立席を含む、または両方の形式があります。

運転免許、乗車定員、速度、シートベルト、バスレーン、停留所、乗降などに特別規則が適用される場合があります。分類や規則は国によって異なるため、現地交通規則に従います。

バス
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.

72. 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。

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.

73. 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.

74. 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.

75. 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.
