An advisory speed is a recommended speed intended to help drivers negotiate a road section or hazard safely.

No. An advisory speed normally provides guidance, while a regulatory maximum-speed sign establishes a legally enforceable speed limit.

Yes. Drivers should reduce their speed further whenever road, traffic, visibility or weather conditions make the recommended speed unsafe.

A road slope is a section of road that rises or descends over a particular distance. It may also be called a gradient, incline or decline.

A steep slope may be indicated by a warning sign showing an ascending or descending road. The sign may also display the gradient as a percentage.

A gradient of 10% means that the road rises or falls approximately 10 metres for every 100 metres travelled horizontally. It does not mean that the road is inclined at 10 degrees.

An ascent rises in the direction of travel, while a descent falls in the direction of travel. The same section of road is therefore an ascent in one direction and a descent in the other.

Not normally. It warns of a hazard rather than setting a numerical limit. Drivers must still respect the applicable speed limit and reduce their speed further when necessary.

Reduce speed before the descent, select a suitable gear and maintain a safe following distance. Avoid allowing the vehicle to gain excessive speed.

Use a gear that provides sufficient engine braking and helps keep the vehicle at a controlled speed. The appropriate gear depends on the vehicle, gradient and road conditions.

No. Coasting reduces engine braking and may make it harder to control the vehicle’s speed. Keep the transmission engaged while descending.

Continuous braking on a long descent can cause the brakes to become excessively hot and lose effectiveness. Select a suitable gear, control speed early and use the brakes progressively when needed.

Brake fade is a reduction in braking performance caused by excessive heat. It can occur when the brakes are used continuously during a long or steep descent.

Select a suitable gear before the engine begins to struggle and maintain a steady speed where possible. Be prepared for heavy or low-powered vehicles travelling slowly ahead.

Yes. Heavy vehicles, vehicles towing trailers and low-powered vehicles may slow considerably. Other drivers should maintain a safe distance and avoid impatient manoeuvres.

Do not overtake when the crest prevents you from seeing far enough ahead. Overtaking near a hilltop may also be expressly prohibited by local law, signs or road markings.

The road surface itself may hide approaching traffic, stopped vehicles, pedestrians or other hazards beyond the crest.

Some countries give priority to uphill traffic, while others rely on signs or ordinary obstruction rules. Drivers must follow local law and cooperate when passing is difficult.

Reduce speed and use a passing place where available. The driver who can reverse or move aside more safely should cooperate, subject to any applicable priority signs or local rules.

They reduce traction and make acceleration, braking and steering more difficult. Increase the following distance, use smooth controls and reduce speed before entering the slope.

Cyclists may travel slowly and move less steadily when climbing, while they may reach high speeds when descending. Drivers should leave sufficient space and avoid overtaking without a clear view.

Use the parking brake, select the appropriate gear or parking position and follow local rules concerning wheel position. Make sure the vehicle cannot roll into traffic.

Yes. A trailer increases the load on the engine and brakes and may affect stability. Drivers should use a suitable gear, maintain additional distance and avoid excessive speed.

A bus stop is a designated location where buses stop so that passengers can board or leave the vehicle.

Watch for buses entering or leaving the stop, passengers near the roadway and pedestrians who may cross the road.

Parking or stopping at or near a bus stop is often restricted or prohibited so that buses can reach the stop safely. The exact restrictions depend on local traffic rules.

A stop sign requires a driver to come to a complete stop and give way before proceeding.

A stop sign is commonly a red octagonal sign displaying the word STOP. Some countries use another legally recognised design, so drivers must learn the signs used locally.

Yes. The obligation to stop applies even when the road appears completely clear.

A complete stop means that the vehicle has ceased moving entirely. Merely slowing down or allowing the vehicle to continue rolling does not satisfy the requirement.

Stop before the stop line where one is provided. Without a line, stop at the legally prescribed position before entering the intersection, crossing or priority road.

No. The required first stop must be made before the line. If visibility is limited, move forward cautiously after stopping and stop again where necessary before proceeding.

Yes. Each driver must make an individual complete stop. Following another vehicle through without stopping is not permitted.

No. After stopping, you must continue to give way to all road users who have priority.

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

A stop sign always requires a complete stop. A give-way sign requires the driver to yield but normally allows continued movement when the road is clearly free.

Yes. After stopping and giving way, you may turn in any direction permitted by signs, signals, lane arrows and road markings.

This depends entirely on local law and traffic signs. A stop sign does not by itself permit a turn against a red light.

No. It imposes a stopping and yielding obligation. The normal posted or general speed limit remains applicable before and after the intersection.

In many countries, cyclists are drivers and must stop unless a specific sign or local rule provides an exception.

The order in which drivers may proceed depends on local rules, commonly involving arrival order, vehicle position and turning direction. Drivers should communicate cautiously and never assume another driver will yield.

Apply the local priority rule and proceed only when the intentions of the other driver are clear. Avoid forcing the other vehicle to brake or change direction.

Where functioning traffic lights control the same movement, they commonly take precedence over the stop sign. Local rules determine what applies when the lights are switched off or flashing.

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

Yes. A correctly placed temporary stop sign at roadworks, an event or another temporary traffic arrangement must be obeyed.

If you recognise that a stop sign applies, reduce speed and obey it. Report damaged, obscured or missing signs to the responsible road authority where appropriate.

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 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.

A school area is a road or group of roads near a school where drivers should expect large numbers of children, pedestrians, cyclists and stopping vehicles.

It may be identified by school warning signs, speed-zone signs, flashing lights, road markings, coloured surfacing or traffic-calming measures. The signs differ between countries.

No. Special school-area rules normally apply only where signs, signals or local legislation establish them.

There is no universal school-area speed limit. The applicable limit depends on the country, region, signs and whether a variable restriction is active.

Some limits apply permanently, while others apply only during displayed times or when flashing or variable signs are active. Drivers must observe the actual sign arrangement.

Yes, when necessary. The displayed speed is a maximum. Children, congestion, poor visibility or vehicles stopping near the school may require a much lower speed.

Children may have difficulty judging speed and distance, may be hidden by parked vehicles and may enter the road unexpectedly.

Reduce speed early, increase your observation and be prepared for children crossing, cyclists changing direction, vehicle doors opening and cars stopping suddenly.

No. Priority depends on crossings, traffic lights, authorised crossing supervisors and local rules. Drivers must nevertheless take exceptional care to avoid endangering children.

Yes. Drivers and other road users must follow lawful instructions given by an authorised person controlling traffic for children.

This depends on local pedestrian rules. Drivers should remain prepared for children to cross unexpectedly, even where they are required to use a nearby crossing.

Not by itself. A school warning sign alerts drivers to children but does not normally create the legal effect of a pedestrian crossing.

No. Traffic lights, priority signs and the ordinary intersection rules remain applicable unless another traffic arrangement provides otherwise.

Overtaking may be restricted by signs or local law. Even where it is permitted, drivers should not overtake when children, crossings, limited visibility or stopped vehicles make the manoeuvre unsafe.

Only where stopping is permitted and can be completed safely. Do not stop on a crossing, pavement, bike path, bus stop or another prohibited or dangerous location.

Follow the parking signs and markings. Do not block entrances, pavements, bike paths, crossings, visibility or access for buses and emergency vehicles.

It blocks traffic and visibility and may force children to walk between moving vehicles or enter the road from behind an obstruction.

Expect children to enter or leave the vehicle and possibly cross the road. Reduce speed and follow any special warning lights, signs or local school-bus rules.

Normally, yes. They must follow the applicable road, bike-path, speed and priority rules. Drivers should expect inexperienced young cyclists.

No. A school area normally remains open to traffic under special caution or speed rules. A school street temporarily restricts or excludes motor traffic during specified periods.

Not universally. A school area may form part of a Zone 30, use another speed limit or have a variable restriction that applies only at particular times.

They normally end at an end sign, at the end of the stated time period or when the variable signal is no longer active. The surrounding road rules then apply.

In right-hand traffic countries, overtaking normally takes place on the left. In left-hand traffic countries, it normally takes place on the right. National rules can provide exceptions in particular situations.

Make sure there is sufficient visibility and space, check mirrors and blind spots, ensure that nobody behind has already started overtaking and confirm that you can safely return to your normal position after passing.

Do not overtake where signs or road markings prohibit it or where visibility, approaching traffic, intersections, crossings, bends, hills or other conditions make the manoeuvre unsafe.

It warns that animals may enter or cross the road in the area ahead.

Depending on the symbol and local conditions, it may refer to deer, cattle, horses, sheep, goats, wild boar or other animals.

It is commonly a triangular warning sign displaying the silhouette of an animal. The species shown may indicate the type of animal most likely to be encountered.

No. It indicates an increased likelihood of animals crossing, not that animals will be present every time.

No. The normal posted or general speed limit remains applicable, but drivers must reduce speed when necessary to react safely.

No automatic priority is created by the warning sign. Drivers must nevertheless avoid danger and allow animals already on the road to pass safely.

Reduce speed, increase your following distance and scan the road, verges, fields and vegetation for movement or reflected eyes.

Animal activity is often greater around dawn, dusk and darkness, although animals may cross at any time.

Many animals travel in groups. When one animal crosses, others may follow immediately from the same direction.

Avoid unnecessary horn use or engine revving because it may frighten an animal and make its movement less predictable. Use a warning only when reasonably necessary to prevent danger.

Use the appropriate lights without dazzling other road users. When an animal is visible, reduce speed and avoid relying on full beam to make it move away.

Slow down smoothly, stop when necessary and allow it enough time and space to leave. Avoid sudden acceleration or aggressive steering.

Avoid an uncontrolled swerve that could cause a collision with another vehicle, tree, barrier, cyclist or pedestrian. Brake firmly while maintaining control and steer only when a safe escape path is clearly available.

Pass only when the animals and their handlers have sufficient space. Drive slowly, avoid noise and be prepared for an animal to change direction unexpectedly.

Reduce speed, leave a large lateral distance and pass quietly. Avoid sounding the horn, accelerating sharply or passing when oncoming traffic prevents sufficient clearance.

Follow lawful instructions from an authorised person and cooperate with handlers controlling animals on or across the road.

The warning sign does not necessarily prohibit overtaking, but overtaking should be avoided when animals, limited visibility or approaching traffic make the manoeuvre unsafe.

Maintain enough following distance to see beyond the vehicle ahead. Be prepared for it to brake suddenly when an animal enters the road.

Reduce speed, keep both hands firmly in control and avoid sudden movements. Animals may react unexpectedly to quiet or fast-approaching two-wheeled vehicles.

Stop safely, activate the hazard warning lights and check for injured people. Contact the emergency services or police when necessary and do not approach a wounded wild animal, which may defend itself.

Normally not. Keep a safe distance and allow the police, wildlife authorities or an animal-rescue service to handle it.

Yes. Drivers remain responsible for observing the road and adjusting their speed even where no animal warning sign is displayed.

A road curve is a section where the road changes direction to the left or right.

It may be indicated by a triangular warning sign showing a curved line. The symbol normally indicates whether the first curve turns left or right.

A double curve consists of two curves in opposite directions. The warning sign normally shows the direction of the first curve.

Yes. A double-curve symbol may also warn of a longer sequence of successive curves. A supplementary panel may indicate the length of the winding section.

No. It normally warns of danger rather than setting a numerical limit. Drivers must still reduce speed when the permitted maximum would be unsafe.

Reduce speed before entering the curve, while the vehicle is travelling straight and has maximum stability.

No. Harsh braking in a curve can reduce stability and grip. Complete most braking beforehand and use smooth adjustments where necessary.

Maintain a controlled speed through the curve. Accelerate smoothly only when the exit becomes visible and the vehicle is stable.

Look towards the path you intend to follow and the visible exit of the curve. Continue checking the road surface, lane position and nearby traffic.

Yes. Do not cross the centre line or cut across another lane, even when this would make the curve appear easier to negotiate.

Buildings, vegetation, slopes, barriers and the road alignment may hide oncoming traffic, cyclists, pedestrians, stopped vehicles or debris.

Choose a speed that allows you to remain in your lane and stop within the distance you can see to be clear. The safe speed may be far below the legal maximum.

An advisory speed is a recommended safe speed for negotiating the curve under suitable conditions. It is not necessarily the legal maximum speed.

They reduce tyre grip and increase the risk of skidding. Reduce speed earlier, use smooth controls and leave additional distance from other vehicles.

Avoid sudden braking or steering. Reduce speed smoothly and follow a clear path without entering another traffic lane.

Do not overtake when visibility is insufficient to see approaching traffic and complete the manoeuvre safely. Local law, signs and continuous road markings may also prohibit overtaking.

Only where it is permitted and the vehicle remains clearly visible. Stopping or parking in a poorly visible curve may create a serious hazard and is often prohibited.

No. Leave enough distance to react if the vehicle ahead brakes for a hidden obstruction or a sharper part of the curve.

Motorcycles require grip for both cornering and braking. Riders should reduce speed before the curve, choose a stable line and avoid painted markings, gravel and slippery surfaces.

A trailer may sway, track closer to the inside of the curve or become unstable when speed and steering inputs are excessive. Enter slowly and steer smoothly.

Buses and trucks may move closer to lane boundaries because of their length and width. Other drivers should avoid travelling beside them through a tight curve.

Reduce speed, move safely towards your side of the road and avoid a sudden manoeuvre that could cause another collision. Sound a warning only when reasonably necessary.

No. Drivers must assess every curve and adapt their speed even when no warning sign is displayed.

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.

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.

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.

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.

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

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

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

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

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.

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.

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.

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

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 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 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.
