Traffic rulesBosnia and Herzegovina

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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

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

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.

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.

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.

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.

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

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.

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

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.

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.

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

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.

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

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.

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.

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

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.

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.

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.

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.

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.

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

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.

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

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.

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

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

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

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

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.

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.

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

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

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

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

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.

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.

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.

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

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

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.

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.

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

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.

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

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.

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

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

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.

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

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.

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

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.

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.

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.

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

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

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

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.

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.

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

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.

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

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.

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.

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

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

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.

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

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

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

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.

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.

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.

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

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.

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.

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

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

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.

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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.

An international border is the legal boundary between two countries.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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.

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.

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

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.

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.

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.

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.

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.

A tourist attraction is a place that visitors travel to because of its cultural, historical, natural, recreational or entertainment value.

Examples include monuments, castles, museums, scenic locations, cultural sites, amusement parks and recreational destinations.

Yes. Many countries use tourist or direction signs to guide travellers toward important attractions and places of interest.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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

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

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.

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.

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.

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

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.

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

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.

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.

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

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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

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.

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

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.

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.

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

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

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

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.

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.

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

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

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

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

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

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

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.

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

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.

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.

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.

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.

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

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

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

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.

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

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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

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

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.

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.

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

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.

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.

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.

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

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.

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.

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.

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

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

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

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

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

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.

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.

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.

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.

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.

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.

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

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

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.

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.

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

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

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.

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.

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.

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.

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.

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

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.
