Traffic signsUnited Kingdom

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.

It warns that rocks or stones may fall onto the road or may already be lying on the carriageway.

It is commonly a triangular warning sign showing rocks falling from a steep slope. The exact colour and design vary between countries.

No. It indicates an increased risk. The road may be clear, contain stones from an earlier fall or become dangerous without additional warning.

Not necessarily. It may also warn about loose or fallen stones already present on the road.

Rockfalls may be caused by erosion, heavy rain, frost and thawing, storms, ground movement, vegetation loss, roadworks or natural instability.

The risk may increase during or after heavy rain, freezing weather, rapid thawing, strong winds, earthquakes or work on a nearby slope.

No. It normally warns of danger rather than setting a numerical limit. Drivers must reduce speed when necessary to react safely.

No. Traffic lights, priority signs and the ordinary priority rules remain applicable.

Reduce speed smoothly, increase your following distance and watch the road surface, slope, barriers and vehicles ahead for signs of falling or fallen material.

No. Leave additional distance so you can see stones on the road and react if the vehicle ahead brakes or changes direction suddenly.

Avoid unnecessary stopping in the exposed section. Stop only when required by traffic, an obstruction or an emergency, and choose the safest available location.

The warning sign does not necessarily prohibit overtaking, but drivers should avoid overtaking when visibility, road width, loose stones or the risk of falling material makes it unsafe.

Avoid doing so. Even where parking is not expressly prohibited, remaining beneath an unstable cliff or slope may expose the vehicle and its occupants to unnecessary danger.

Reduce speed without harsh steering or braking. Pass only when there is enough clear space and visibility; otherwise, stop at a safe distance and report the obstruction.

Avoid a sudden uncontrolled swerve. Brake while maintaining control and steer around the obstruction only when the adjacent space is clearly safe.

Stop at a safe distance, activate the hazard warning lights when appropriate and contact the police, road authority or emergency services. Do not attempt to drive over unstable debris.

Do not enter the affected section. Stop well before the danger where possible and move away only when this can be done safely without reversing blindly or entering another hazard.

Do not stand near the unstable slope or falling material. Leave the vehicle only when remaining inside creates a greater immediate danger and a protected escape route is available.

Normally not. A stone may be too heavy, unstable or followed by additional falling material. Keep a safe distance and allow trained services to clear the road.

Even small stones can cause a rider to lose balance or damage a tyre. Riders should reduce speed, avoid sudden steering and keep a greater distance from other traffic.

No. Nets, barriers and retaining structures reduce the risk but cannot guarantee that every stone will be contained.

It may indicate how far ahead the danger begins. Another panel may indicate the length of the hazardous road section.

Keep control of the vehicle, stop at a safe location and activate the hazard warning lights. Check the tyres, wheels and underside only when it is safe and report any dangerous debris.

No. Drivers must remain attentive wherever roads run beside cliffs, cuttings or steep slopes, even when no warning sign is displayed.

An aircraft warning alerts drivers that aircraft may pass at low altitude over or near the road.

They are commonly used near airports, airfields and flight paths where low-flying aircraft or sudden aircraft noise may surprise road users.

Continue to concentrate on the road and avoid sudden braking, steering or other unnecessary manoeuvres because of the aircraft.

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.

A road chevron is a V-shaped or arrow-shaped marker used to guide drivers through a curve or another sharp change in road direction.

It is normally displayed on a rectangular board using strongly contrasting colours. Several chevrons may be placed in sequence around a curve.

The point of the chevron indicates the direction in which the road continues. A chevron pointing left guides traffic through a left curve, while one pointing right guides traffic through a right curve.

They are generally placed along the outside of a curve, facing approaching traffic so that drivers can clearly see the road alignment.

A series of chevrons visually traces the curve and helps drivers judge its direction, length and changing alignment.

No. A curve-warning sign normally warns drivers before the curve. Chevron boards are usually positioned within or around the curve to guide drivers through it.

No. It guides drivers through the change in direction but does not normally introduce a numerical speed limit.

Not by itself. A separate advisory-speed or speed-limit sign may indicate an appropriate or legally required speed.

No. Traffic lights, priority signs and the ordinary priority rules remain applicable.

It normally indicates that the curve requires additional visual guidance. Drivers should expect a noticeable or potentially sharp change in direction.

Not directly. The number and spacing depend on the length, radius and design of the curve and on the road authority’s signing standards.

Not necessarily. Larger boards may be used where approach speeds are higher or where greater visibility is needed.

Reduce speed before the curve, observe the direction of the boards and remain within your traffic lane.

No. Complete most braking before entering the curve and use smooth steering, braking and acceleration while following it.

No. The boards normally mark the outside edge of the curve. Follow the road around them rather than steering towards them.

No. Remain within your lane and do not enter the path of oncoming traffic.

The chevrons do not automatically prohibit overtaking, but overtaking is unsafe when the curve restricts visibility or available road width.

Reflective material makes the boards easier to see in darkness and poor weather when illuminated by vehicle headlights.

Yes. Some high-risk curves use illuminated or flashing chevrons to make the change in direction more conspicuous.

Yes. Their colours and design vary between countries, but contrasting colours are used to make the direction clearly visible.

Reduce speed before the curve, choose a stable path and look through the turn. Do not focus exclusively on the chevrons or allow the motorcycle to cross the centre line while leaning.

No. Drivers must assess every curve and select a safe speed whether or not chevron boards are installed.

Wrong-way driving means travelling against the legally permitted direction of traffic.

It can occur on one-way streets, divided roads, motorways, slip roads, tunnels, car parks and temporary traffic arrangements.

Other drivers do not expect approaching traffic in their lane, and the combined speeds can make a head-on collision extremely severe.

Look for no-entry signs, one-way signs, mandatory-direction signs, lane arrows and road markings. Motorway exits may also have repeated signs or warning systems facing the wrong direction.

Entering past a no-entry sign can cause wrong-way driving, but the term also covers turning around on a divided road or using the wrong carriageway without passing such a sign.

Normally, yes. However, signs may expressly permit certain road users, such as cyclists or public transport, to travel in the opposite direction.

No. A cyclist, bus or other road user travelling in an expressly authorised contraflow lane or direction is using the road legally.

Yes. Temporary signs, barriers, lane signals and markings may redirect traffic onto another lane or carriageway. Follow the temporary arrangement rather than the usual road layout.

Reduce speed immediately, keep as far as safely possible towards the outer edge of your carriageway and avoid sudden lane changes. Warn the police or emergency services as soon as this can be done safely.

No. Do not block, chase or turn after the vehicle. Protect yourself and allow trained emergency services to intervene.

A brief warning may help the driver recognise the error, but avoid prolonged or aggressive signalling that could cause panic or an unpredictable manoeuvre.

Use the horn only when reasonably necessary to warn of immediate danger. Your first priority is to reduce speed and create as much safe space as possible.

Normally not. Sudden stopping may cause a rear-end collision. Slow down and move towards a safe shoulder, refuge or other protected location where possible.

Reduce speed, stop overtaking, increase your following distance and remain in the lane or position recommended by the local authorities or warning system.

Avoid unnecessary use of lanes nearest opposing or central traffic when a wrong-way driver has been reported. Follow local emergency guidance and electronic signs.

Slow down immediately, activate the hazard warning lights and use dipped headlights where required. Move to the safest available edge or shoulder and stop.

No. Increasing speed greatly increases the collision risk. Stop safely and wait for instructions from the police.

No. Do not turn across live lanes, cross a central reservation or attempt to correct the mistake through another dangerous manoeuvre.

No. Reversing against traffic or along a motorway slip road creates additional danger. Stop safely and contact the emergency services.

This depends on the location and immediate danger. Remain protected from moving traffic and follow instructions from the emergency services. Do not stand in a live lane.

Stop safely before using a handheld phone. A passenger may call while the vehicle is moving when local law permits and this can be done without distracting the driver.

Report the road name or number, direction, nearby exit or landmark, vehicle description and the wrong-way driver’s approximate location and direction.

Possible causes include confusion at junctions, poor visibility, unfamiliar roads, impairment, navigation errors, turning around illegally or deliberately ignoring traffic signs.

Slow down at unfamiliar junctions, read signs before turning, verify the road layout and do not rely exclusively on navigation instructions.

No. Traffic signs, signals, markings and instructions from authorised persons always take precedence over navigation guidance.

Roadworks are construction, maintenance, repair or inspection activities carried out on or beside a road.

They may be indicated by a roadworks warning sign, cones, barriers, temporary markings, flashing lights, machinery or workers.

No, not by itself. A separate temporary or permanent speed-limit sign establishes the legal maximum speed.

Yes, when necessary. Narrow lanes, workers, machinery, poor surfaces, congestion or limited visibility may require a substantially lower speed.

Yes. Correctly installed temporary signs must be obeyed for as long as they are in force.

Follow the temporary markings that guide traffic through the works. Local law determines how they take priority over older permanent markings.

Yes. Stop at the line or signal when required and do not proceed until the applicable light permits it.

Obey instructions from workers or controllers who are legally authorised to regulate traffic. Their signals may temporarily replace the ordinary traffic arrangement.

Observe the signs and lane arrows, check mirrors and blind spots and merge safely into the continuing lane.

Zipper merging means that vehicles in an ending or blocked lane merge alternately with vehicles in the continuing lane near the narrowing during congested traffic.

This depends on local law and traffic conditions. Where zipper merging applies during congestion, use both lanes and merge near the narrowing. In flowing traffic, change lanes when a safe gap is available.

Without another traffic control, the driver whose route is obstructed commonly has to yield before moving into the path of approaching or adjacent traffic.

Yes. Temporary signals may allow only one direction at a time through a narrow section.

No. Do not enter a narrow section, intersection or temporary crossing when congestion may leave you stopped inside it.

No. Do not move, pass around or ignore traffic-control equipment unless an authorised person instructs you to do so.

Only when signs and markings permit it and sufficient width and visibility remain. Overtaking is often unsafe in narrow or shifted lanes.

Only where temporary and permanent signs permit it. Do not obstruct workers, machinery, emergency access or temporary pedestrian and cycle routes.

Expect workers to enter the road, machinery to move or reverse and vehicles to leave the worksite. Reduce speed and leave generous space.

Follow the signed temporary cycle route or lane. Check surrounding traffic carefully before leaving a closed or obstructed bike path.

Use the designated temporary walkway or crossing and follow barriers, signs, signals and instructions from authorised personnel.

Traffic may brake suddenly because of queues, lane changes, machinery, debris or changing signals. Additional distance provides more time to react.

Move to the safest available location where possible, activate the hazard warning lights and contact assistance. Avoid standing in a live or narrow traffic lane.

Yes. Rules concerning safe speed, following distance, signalling, priority and vulnerable road users continue to apply unless a lawful temporary arrangement changes them.

It prohibits vehicles whose total height exceeds the displayed value from continuing beyond the sign.

It is commonly a circular regulatory sign showing a height in metres, feet or another local unit between vertical arrows.

The height includes the vehicle, its load and any attached equipment, such as roof boxes, bicycles, machinery, antennas or raised loading equipment.

Yes. Every part of a vehicle combination must fit beneath the restriction, including the towing vehicle, trailer and load.

Not necessarily. Road authorities may display a lower value than the measured clearance to provide a safety margin.

The legal wording commonly prohibits vehicles higher than the displayed value, but drivers should not attempt to pass without a practical safety margin. Measurement errors, movement and road conditions can reduce the available clearance.

Loading, tyre pressure, suspension settings, raised equipment, replacement tyres and road movement can alter the vehicle’s total height.

Yes. The vehicle may rise or lower depending on its suspension mode, speed and load. Use the maximum travelling height when planning the route.

Yes. An arched bridge, tunnel roof or overhead structure may provide different clearance in each lane. Follow lane-specific signs and markings.

Yes. Clearance may be lower near the edge of an arch or where the road slopes sideways. Remain within the authorised marked path.

Yes. A new road surface can raise the road level and reduce the space beneath a bridge or structure.

Yes. Material on the road can raise the vehicle or restrict the usable route. Flooding may also conceal the road surface or another hazard.

They are common at bridges, tunnels, car parks, loading areas, gateways, railway structures and roads with overhead equipment.

It is normally a prohibition. A vehicle that exceeds the displayed height may not pass.

No. The applicable road or posted speed limit remains in force, although drivers should approach cautiously.

No. Traffic lights, priority signs and ordinary priority rules remain applicable.

Yes. An advance sign may show the restriction and the distance to it so that high vehicles can choose another route.

Do not continue. Stop where safe and follow the signed diversion or another suitable route. Do not reverse into traffic without assistance.

No. Navigation may contain outdated or incomplete vehicle restrictions. Traffic signs and the actual road conditions always take precedence.

Yes. Drivers of trucks, buses, motorhomes and vehicles carrying roof loads should know and, where useful, display the vehicle’s maximum travelling height inside the cab.

Stop before the restriction in a safe place and verify the vehicle’s height. Choose another route when safe clearance cannot be confirmed.

Only when signs and markings permit it and the manoeuvre can be completed safely. Do not cross a closed lane, continuous line or opposing traffic merely to gain clearance.

Only in a safe place and when the equipment can be secured correctly afterwards. Never stop beneath the structure or in a live lane to alter the vehicle.

Stop immediately where safe, activate the hazard warning lights and contact the emergency services or police. Do not continue because the vehicle, load or structure may be unstable.

No, when damage may have occurred. Keep away from the structure and follow instructions from the police, road authority or railway operator.

It warns that vehicle speeds may be measured or enforced on the road ahead or throughout a specified section.

No. A speed-limit sign establishes the maximum legal speed. A radar sign only warns that compliance with an applicable limit may be monitored.

Check the most recent speed-limit sign, variable sign, speed-zone sign or general limit applying to the road and vehicle category.

No. It does not normally change the existing limit. Drivers must nevertheless travel more slowly when traffic, visibility, weather or road conditions require it.

It may announce a permanent camera, a mobile-control area or a section where enforcement can occur. The exact meaning depends on the country and sign design.

No. Drivers should never rely on assumptions about whether equipment is operating and should respect the speed limit at all times.

A fixed speed camera is permanently installed at a particular location and measures the speed of passing vehicles.

A mobile speed camera is temporarily positioned in a police vehicle, trailer, roadside unit or another approved location.

Lidar uses laser pulses to measure the speed and position of vehicles. It may be used by police officers or in temporary automatic installations.

Average-speed enforcement records a vehicle at two or more points and calculates its average speed across the controlled section.

No. Average-speed enforcement considers the travel time across the complete measured section rather than speed at only one point.

Yes. Some systems monitor vehicle speed and whether a vehicle passes a red traffic signal.

No. Some authorities announce speed cameras, while others permit enforcement without advance warning. The rules differ between countries and regions.

Yes. The absence of a warning sign does not normally prevent police or authorised authorities from carrying out a lawful speed check.

The applicable limit remains a maximum rather than a target. Drivers must reduce speed whenever travelling at that limit would be unsafe.

No. Check your speed and reduce it smoothly when necessary. Sudden braking can cause a rear-end collision.

Only while remaining within the applicable limit and driving safely. The restriction may continue, and another camera or average-speed section may follow.

No. Passing a camera or radar sign does not end the applicable speed restriction.

A radar speed display measures an approaching vehicle and shows its current speed, sometimes with a colour, message or smiley symbol.

Not necessarily. Many displays are preventive devices intended to make drivers aware of their speed and may collect anonymous traffic statistics without issuing penalties.

No. The roadside display is generally informational. Drivers remain responsible for observing the vehicle’s speedometer and the legal speed limit.

Yes. The technical ability to measure a motorcycle and the method used to identify it depend on the enforcement equipment.

Yes. Modern systems may measure vehicles in one or more lanes and may distinguish between traffic directions or vehicle categories.

Yes. Heavy vehicles, buses, trailers or other vehicle categories may be subject to lower limits than passenger cars on the same road.

Release the accelerator and reduce speed smoothly and safely. Do not brake harshly or make an abrupt lane change.

A selective barrier is a physical access-control device that blocks some traffic while allowing specified road users or authorised vehicles to pass.

Common examples include fixed bollards, removable posts, folding posts, retractable bollards, gates, rising barriers and width-filtering installations.

They may prevent through traffic, protect pedestrian or cycling routes, control access to restricted areas or allow only residents, public transport, deliveries or emergency services to enter.

Not normally. The permitted users are determined by traffic signs, permits, access systems and local regulations.

Only when cycling is permitted and sufficient safe space is provided. Cyclists must follow the signs applying to the road or path.

Pedestrians may pass where pedestrian access is permitted and a safe route is available. They should not walk beneath a moving gate or through a vehicle-only opening.

Only when motorcycles are legally permitted beyond the barrier and the opening is intended for them. Being physically able to fit through does not create permission.

Emergency vehicles may have keys, remote controls, automatic recognition or another authorised method of opening the barrier. Other road users must keep the access clear.

They may enter only when local access rules, permits or traffic signs authorise them. Permission may apply only during specified hours.

A retractable bollard is a post that can rise from or lower into the road surface to control vehicle access.

It may operate through a badge, remote control, access code, number-plate recognition, timer, control centre or automatic detection system.

Only after confirming that you are authorised and the bollard is fully lowered. Do not move merely because another vehicle has activated it.

No, unless your own access is also authorised and the system clearly permits it. The barrier may rise immediately after the first vehicle.

Red lights normally require road users to stop, while another signal may indicate when passage is permitted. Follow the displayed signals and local instructions.

Stop at a safe distance and wait until it has completed its movement. Never drive, cycle or walk beneath a moving gate or across a rising bollard.

Do not force, move or drive around it. Use the intercom or contact the operator, road authority or emergency service indicated at the location.

No, unless you are specifically authorised. Removing or repositioning access-control equipment may create danger and allow prohibited traffic to enter.

No. Traffic signs and access restrictions remain applicable even when the physical barrier is temporarily open or lowered.

No. An open physical barrier does not cancel a regulatory traffic sign.

Not by itself. Drivers must follow the applicable speed limit and approach slowly enough to stop before the installation.

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

Do not stop or park where the vehicle would block authorised access, emergency services, pedestrians or cyclists.

They may be difficult to see, especially in darkness, congestion or poor weather. A collision can cause a rider to fall into nearby traffic or other obstacles.

Reduce speed, identify the intended opening and pass through in a straight and controlled line. Avoid overtaking another cyclist at the barrier.

Approach slowly, wait for the access system to respond and check for pedestrians and cyclists before crossing their route.

Stop safely, activate the hazard warning lights where appropriate and report the collision. Do not continue if the vehicle, barrier or access system may be damaged.

A low-emission zone is an area where access by more polluting vehicles is restricted in order to improve air quality.

They are intended to reduce traffic-related air pollution, particularly pollutants produced by older or higher-emitting vehicles.

Restrictions may apply to cars, vans, trucks, buses, motorcycles or other motor vehicles, depending on the local regulations.

Access commonly depends on the vehicle's fuel type, Euro emission standard, vehicle category and sometimes other technical characteristics.

A Euro emission standard indicates which European pollutant-emission requirements a vehicle satisfies. Higher Euro numbers generally represent newer and stricter emissions requirements.

Not necessarily. Low-emission zones often apply different access criteria to diesel and petrol vehicles because their pollutant-emission characteristics differ.

Fully electric vehicles are generally permitted because they produce no combustion-engine exhaust emissions while driving, although local registration or administrative requirements may still apply.

Some low-emission zones provide exemptions, temporary permits or day passes for certain vehicles or circumstances.

Traffic signs normally indicate the entrance and exit of the zone. Drivers should check the applicable restrictions before passing the entry sign.

Enforcement may use automatic licence-plate cameras, roadside controls or registration databases. The exact system varies between cities and countries.

Yes. Foreign vehicles must comply with the applicable access criteria and may also have to complete an online registration before entering.

No. Each country, region or city can establish different boundaries, emission requirements, exemptions and enforcement procedures.

It means that drivers travelling on the indicated road have priority over traffic entering from intersecting roads at the next junction.

No. Priority at the next junction applies to one particular junction. A priority road normally keeps its priority across several junction until its status ends.

No. The term main road may describe a larger, busier or more important road, but legal priority is determined by traffic signs, signals and local rules.

It may be indicated by a priority-junction sign showing a thick line for the priority route and thinner lines for the roads that must give way.

Yes. On signs using a junction diagram, the thicker line normally represents the road followed by traffic with priority.

No. The priority route may turn left or right. A diagram or supplementary panel may show which branch retains priority.

They commonly face a give-way or stop sign, requiring them to yield to traffic on the priority route.

Not when legally placed signs establish another priority arrangement at that junction. Drivers must follow the actual signs rather than the ordinary default rule.

No. After passing the indicated junction, the priority arrangement at the next junction must be determined separately.

No. Approach at a safe speed and remain prepared for another road user to fail to give way.

No. Priority is not an obligation to continue. Slow down or stop whenever proceeding would create danger.

No. Do not enter when congestion is likely to leave your vehicle stopped inside the junction and obstructing other traffic.

No. The applicable general, zonal, posted or vehicle-specific speed limit remains in force.

No. Drivers must still yield to pedestrians where crossings, traffic signals or turning rules require it.

It regulates priority between traffic approaching the junction, but drivers must still respect continuing bike paths, cycle crossings and turning rules.

Yes, when following the route involves a change of direction and local law requires signalling. Priority does not remove the obligation to indicate.

No. An indicator communicates your intended movement but does not allow you to endanger or obstruct another road user.

Normally, yes. Priority over side-road traffic does not automatically give a left-turning driver priority over lawful oncoming traffic.

Functioning traffic lights normally control the junction instead of the priority signs. Local rules determine what applies when the lights are switched off or flashing.

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

No. Overtaking remains subject to the ordinary rules, visibility, road markings and any separate prohibition signs.

No. The ordinary stopping and parking rules and any local signs or markings remain applicable.

The special priority indicated by the sign has been completed. At later junctions, follow the signs, signals or default priority rule applying there.

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.

A traffic lights warning alerts drivers that traffic signals are located ahead.

It may be used where traffic lights are unexpected, difficult to see sufficiently early or located on a road where advance warning improves safety.

Remain alert, reduce speed when necessary and be prepared to stop at the traffic lights or behind waiting traffic.

Road markings are lines, symbols, arrows or words placed on the road surface to regulate, guide or provide information to road users.

They can separate traffic lanes, indicate stopping or priority points, guide traffic movements and mark crossings or reserved areas.

No. Many markings are internationally similar, but their colours, designs and exact legal meanings can vary between countries.

A climbing lane is an additional lane on an uphill section of road that provides space for slower vehicles while allowing faster vehicles to continue past them.

Climbing lanes are generally intended for vehicles travelling substantially slower than the normal traffic flow, particularly heavy vehicles. The exact restrictions depend on local signs and traffic rules.

Follow the road markings and signs, check surrounding traffic and merge safely into the continuing traffic lane without forcing other road users to brake or change direction suddenly.

A bike box is a marked waiting area at a signal-controlled intersection where cyclists can position themselves ahead of motor vehicles during a red light.

They help make cyclists more visible to drivers and allow cyclists to position themselves according to the direction they intend to travel.

Normally, no. Motor vehicles should stop behind the stop line provided for them so that the designated cyclist waiting area remains clear.

Left-hand traffic means that vehicles normally drive on the left side of a two-way road. Traffic approaching from the opposite direction therefore passes on the driver's right.

Vehicles normally overtake on the right, although exceptions can apply depending on the road layout and national traffic rules.

Most vehicles designed for left-hand traffic have the steering wheel on the right-hand side. However, vehicles with the steering wheel on the opposite side can also be legally used in many countries.

A speed feedback display is an electronic roadside device that measures an approaching vehicle's speed and shows that speed to the driver.

They are used to increase drivers' awareness of their actual speed and encourage compliance with the applicable speed limit.

Normally, no. The legally applicable speed is determined by the traffic rules and regulatory speed-limit signs, while the feedback display simply informs the driver of their measured speed.

A driving licence is an official authorisation to drive specified categories of motor vehicle.

The terms may refer to the same document, depending on the country. Some countries use permit specifically for learners or temporary authorisations.

A provisional or learner licence allows a person to practise driving under specified restrictions before obtaining a full licence.

A full licence is issued after the holder has completed the required tests or training. Restrictions may still apply because of age, vehicle type, medical fitness or licence codes.

No. Driving licences are divided into categories for motorcycles, cars, buses, trucks, trailers and other vehicles.

A licence category identifies the type and size of vehicle the holder is authorised to drive.

Yes. Holding a licence for one category does not normally authorise driving a vehicle belonging to another category.

Yes. Codes may restrict the holder to an automatic transmission, corrective lenses, an adapted vehicle or another specified condition.

In some countries, passing the test in an automatic vehicle restricts the holder to automatic vehicles until an additional test or procedure is completed.

Usually, yes. The document, individual categories or medical authorisation may have expiry dates and require renewal.

No. The licence and the category required for the vehicle must remain valid.

This depends on local law. Many countries require drivers to carry the original licence and present it to an authorised officer when requested.

Not normally. A photograph, scan or photocopy is not generally a substitute for the original document unless an official digital-licence system is legally recognised.

No. It proves driving authorisation, not ownership, registration or insurance.

Requirements may include a theory test, eyesight test, practical driving test, medical examination or compulsory training.

No. Minimum ages differ between countries and vehicle categories.

Only where the provisional-licence system permits independent driving. Other learners must be accompanied by an approved supervisor or instructor.

Often not. Provisional and learner licences are frequently valid only in the country or region that issued them.

An international driving permit is a standardised translation of a valid national licence intended to help authorities interpret it abroad.

No. It normally has legal value only when presented together with the valid national driving licence on which it is based.

This depends on the destination, length of stay, residence status and agreements between the countries concerned. An exchange or international permit may be required.

Some countries exchange recognised foreign licences without new tests, while others require theory, practical or medical examinations.

Yes. A medical condition may require an assessment, shorter validity period, adapted vehicle or licence restriction.

This depends on local law. Drivers remain responsible for ensuring that they are physically and mentally fit to drive safely.

Often, yes. Drivers of trucks, buses, taxis or vehicles used commercially may require professional competence, medical examinations or periodic training.

The holder may not drive during the suspension period, even if the physical document remains in their possession.

Disqualification is a legal prohibition on driving, usually imposed by a court or competent authority for a specified period or until conditions are fulfilled.

Report it where required and apply for a replacement through the competent licensing authority. Do not continue driving when local law requires the original document to be carried.

Request a replacement when the document is unreadable, damaged or no longer allows the holder to be identified reliably.

This depends on the country and whether the address appears on the licence. Drivers must follow the local notification and replacement procedure.

Cycling routes are commonly indicated by direction signs, bicycle symbols, route numbers, colours or destination markers. The design of the signs and route-numbering system varies between countries and regions.

Usually not. A cycling-route sign normally provides direction or route guidance rather than imposing a mandatory direction. However, separate mandatory traffic signs may require cyclists to use a particular cycle path or direction.

No. A cycle path is a specific part of a road or separate path intended for cyclists under local traffic rules. A cycling route is an entire itinerary and may include cycle paths, ordinary roads, cycle streets and other types of infrastructure.

Not necessarily. Many cycling routes use roads and paths that are also open to motor vehicles, pedestrians or other road users. Access is determined by the signs and rules applying to each individual section.

Not automatically. Being on a designated cycling route does not normally change the priority rules. Cyclists must continue to obey traffic lights, give-way and stop signs, crossing rules and other applicable traffic regulations.

No. A route may combine dedicated cycle infrastructure with quiet streets, shared roads, rural roads and other suitable connections. The quality and level of separation from motor traffic can therefore change along the route.

Yes. A cycling route may cross or temporarily follow busy roads. At such locations, cyclists must follow the crossing, priority and traffic-light rules indicated by local signs and markings.

Yes, unless access is restricted by separate traffic signs or regulations. A cycling-route designation by itself does not normally prohibit cars, motorcycles or other vehicles from using an otherwise public road.

Yes. Cycling routes may be designed for daily travel, tourism or recreation. Some form part of regional, national or international networks and may be identified by route names or numbers.

Always follow the official traffic signs, signals and road markings. A route marker provides navigation and does not override a prohibition, mandatory direction, road closure or other traffic regulation.

Parking generally means leaving a vehicle stationary for longer than a brief stop required for passengers, loading or unloading. A vehicle stopped because of traffic lights, congestion, an emergency or another traffic condition is normally not considered parked. The precise legal definitions vary between countries.

Look for parking signs, prohibition signs, road markings and parking-zone signs. Local rules may also permit parking along certain roads even when individual parking spaces are not marked.

No. General traffic rules can prohibit parking even when no specific prohibition sign is present. Common examples include locations where a parked vehicle would obstruct visibility, crossings, intersections, cycle facilities or the movement of other traffic.

Parking on a pavement or sidewalk is prohibited or restricted in many countries unless signs or markings specifically allow it. Vehicles must not force pedestrians into the roadway or block an accessible pedestrian route.

Parking on or close to a pedestrian crossing is generally restricted because a vehicle can hide pedestrians from approaching drivers. The required clearance distance varies between countries.

Many countries prohibit parking within a specified distance of an intersection because parked vehicles can reduce visibility and obstruct turning traffic. Follow the local distance requirements and any signs or markings.

A parking sign identifies a place or area where parking is permitted or regulated. Additional signs or panels may specify time limits, payment requirements, vehicle categories, permits or particular parking arrangements.

Where parking is subject to payment, drivers must follow the instructions displayed locally. Payment may be made through a parking meter, ticket machine, mobile application or another authorised system. The permitted duration and charging periods vary by location.

Spaces marked for people with disabilities are reserved for vehicles displaying or registered with the required disability parking permit. Eligibility, permit display requirements and parking privileges depend on national and local law.

Not necessarily. Local rules may impose a maximum parking duration, even where parking is otherwise permitted. Different limits may apply to abandoned, commercial, heavy or recreational vehicles.

A no-parking sign prohibits leaving a vehicle parked in the area or along the section of road to which the restriction applies. The exact legal definition of parking and the extent of the prohibition vary between countries.

No. A no-parking restriction commonly still permits certain brief stops, such as picking up or dropping off passengers or loading or unloading goods. A no-stopping restriction is stricter and generally prohibits voluntary stopping as well as parking.

Remaining inside the vehicle does not necessarily mean that it is not parked. If the vehicle remains stationary beyond what local law permits as a brief stop, it may legally be considered parked even when the driver stays inside.

Often yes, if stopping is permitted and the vehicle remains there only as long as reasonably necessary for passengers to get in or out. Local rules may impose stricter restrictions at particular locations.

In many countries, genuine loading or unloading is treated as stopping rather than parking and may therefore be permitted. The vehicle should remain there only for the time reasonably necessary for the activity.

This depends on the country's signing rules. The restriction may continue to the next intersection, an end sign, a stated distance or the end of a designated zone. Supplementary arrows or distance panels may indicate its exact extent.

Usually a roadside no-parking sign applies only to the side of the road on which it is placed, unless it forms part of a zonal restriction or local signs indicate otherwise.

Yes. A supplementary panel may restrict the prohibition to particular hours, days or periods. Outside those periods, parking may be permitted if no other rule prohibits it.

Yes. Additional signs or symbols may make a parking restriction applicable to particular vehicle categories, such as heavy vehicles, motorcycles or other specified vehicles.

Only if parking is otherwise legal. The end of a specific no-parking restriction does not override general parking prohibitions near crossings, intersections, driveways, traffic signs or other protected locations.

P+R stands for park and ride. It indicates a facility where drivers can park their vehicle and continue their journey using public transport or another form of transport.

They are commonly located on the outskirts of cities, near major roads or beside railway, metro, tram or bus connections so that drivers can transfer conveniently to another mode of transport.

No. Some facilities are free, while others charge for parking or offer special combined parking and public-transport fares. Conditions depend on the individual facility and local authority.
