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.

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.

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 prohibits vehicles or vehicle combinations whose relevant mass exceeds the value displayed on the sign.

It is commonly a circular regulatory sign showing a mass in tonnes, kilograms or another local unit.

It is normally a prohibition. A vehicle exceeding the displayed limit may not continue beyond the sign.

Actual loaded mass is the weight of the vehicle as it is currently travelling, including the vehicle itself, its load, driver, passengers and other relevant equipment.

Maximum authorised mass is the highest total mass at which the vehicle is legally approved to operate. It is normally recorded in the vehicle documents.

No. A lightly loaded vehicle may have an actual mass below its maximum authorised mass. A restriction may legally refer to either measurement, depending on the sign and local law.

Yes. Cargo, passengers, fuel, equipment and other carried items may all contribute to the vehicle’s actual loaded mass.

Where the restriction concerns actual loaded mass, the driver and other occupants are normally included.

This depends on the wording of the restriction. It may apply to each vehicle separately or to the combined mass of the complete vehicle combination.

An axle-weight limit restricts the amount of mass carried by one axle or axle group rather than the total mass of the vehicle.

A vehicle may comply with the total weight limit while too much of its load is concentrated over one axle, creating excessive stress on the road or bridge.

They are often used at bridges, weak roads, historic centres, tunnels, temporary structures and roads unsuitable for heavy traffic.

Not necessarily. The displayed legal limit may include engineering and safety margins and should not be interpreted as the structure’s exact failure point.

A sign normally prohibits vehicles exceeding the displayed value. The driver must still be certain that the relevant mass does not exceed it.

The most reliable method is to use an authorised or suitable weighbridge. Vehicle documents alone normally show approved limits rather than the vehicle’s current loaded mass.

An estimate may help with planning, but it must include the vehicle, fuel, occupants, equipment, load and trailer. A weighbridge is preferable when the remaining margin is small.

No. Moving cargo within the vehicle does not change its total mass, but it can change the load carried by each axle.

Yes, when done lawfully and safely. The vehicle may continue only after its relevant mass complies and the remaining load is properly secured.

Yes. Temporary restrictions may protect a damaged bridge, weakened road, roadworks structure or road affected by flooding or thawing.

Yes. Lane-specific signs may direct heavier vehicles towards a lane or structure designed to carry them.

Yes. Advance signs may give the distance to the restriction or indicate a diversion so affected vehicles can choose another route.

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

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

Do not continue. Stop where safe and follow a signed diversion or another route suitable for the vehicle’s mass.

No. Navigation information may be incomplete or outdated. Traffic signs and official restrictions always take precedence.

Only when reversing is lawful and can be completed safely. Use assistance where necessary, particularly with a long or heavy vehicle combination.

The vehicle may damage the road or structure and may be stopped, fined, unloaded or prohibited from continuing under local law.

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.

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.

Pedestrian lights are traffic signals that indicate when pedestrians may begin crossing a road.

They commonly display a red standing person and a green walking person. Their design may vary between countries.

It means that pedestrians must not begin crossing.

It means that pedestrians may begin crossing, provided they still observe the road and cross without unnecessary delay.

No. Turning vehicles, emergency vehicles or traffic following another authorised signal may still cross the pedestrian route. Pedestrians should remain attentive.

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

Its meaning varies between countries. It commonly means that pedestrians must not begin crossing, while those already on the road should finish without delay.

A countdown may show approximately how much time remains before the signal changes. It does not remove the duty to cross cautiously.

Begin only when there is enough time to cross safely and without stopping unnecessarily on the road. Waiting for the next green phase may be safer.

Continue crossing at a normal pace towards the nearest safe side. Do not turn back suddenly, stop unnecessarily or run into another traffic stream.

Yes. Drivers should allow pedestrians who entered lawfully to complete the crossing safely, even when vehicle traffic receives permission to proceed.

Some signal systems permit turning vehicles and pedestrians at the same time. Turning drivers must give way where required and must not endanger pedestrians.

It is a signal phase during which conflicting vehicle movements are stopped so pedestrians can cross without permitted traffic turning across their route.

It is a phase in which pedestrians may cross several or all approaches while vehicle traffic is stopped. Diagonal crossing is permitted only when the signals and markings allow it.

They may indicate that the same pedestrian signal applies simultaneously to several crossing directions. The exact meaning depends on local law.

Check that approaching and turning vehicles are stopping and that the route is clear. A green signal does not make a collision impossible.

Yes. They should proceed at a normal pace and should not linger, stop unnecessarily or obstruct traffic on the crossing.

Pedestrians may have to follow the traffic lights controlling vehicles, an authorised officer or the ordinary pedestrian-crossing rules.

A push button normally registers a request for a pedestrian crossing phase. Pressing it does not itself permit crossing; pedestrians must wait for the appropriate signal.

Normally not. Once the request has been registered, additional presses usually have no effect.

Audible signals use sounds to help pedestrians with visual impairments identify when crossing is permitted or when the signal is changing.

Tactile signals may use a vibrating button, rotating cone or raised markings to provide crossing information to pedestrians with visual impairments.

Not normally. A cyclist riding a bicycle must follow the applicable cycle or vehicle signal unless a combined pedestrian-and-cycle signal applies.

A person walking beside a bicycle is normally treated as a pedestrian and follows the pedestrian signal.

They display pedestrian and bicycle symbols and apply to the road users indicated by those symbols.

No. Instructions from an authorised traffic controller normally take precedence over pedestrian lights.

Cross only according to the functioning vehicle signals, priority rules and instructions from authorised personnel. Proceed cautiously and take approaching traffic into account.

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 crossroad shape is a simplified diagram showing the physical arrangement and directions of roads at an upcoming intersection.

It helps drivers understand the junction layout in advance and choose the correct direction before reaching the intersection.

No. These diagrams are normally simplified and may omit features such as traffic islands, medians or other minor road details so that the important directions remain easy to understand.

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.

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 road location marker is a numbered reference point identifying a measured position along a particular road or route.

A kilometre marker indicates the number of kilometres measured from an established starting point on the road.

A hectometre marker identifies a position at intervals of 100 metres. One kilometre contains ten hectometres.

It normally identifies a point approximately 14 kilometres and 700 metres from the route’s reference origin.

No. It normally measures the position along the road from a fixed reference origin rather than the remaining distance to a destination.

It begins at a reference point chosen for that road, such as the start of the route, a border, an administrative boundary or another officially defined origin.

No. It increases in the officially defined direction of the route. Drivers travelling in the opposite direction may see the values decrease.

It may appear as a numbered roadside post, small sign, plate, marker attached to a barrier or numbers painted beside the carriageway.

Many countries use kilometre markers, while countries using imperial measurements may use mile markers. Designs and intervals differ.

They are intended to represent 100-metre intervals, but their physical placement and permitted tolerances depend on the road authority and local conditions.

Give the road number, marker value, direction of travel and nearest junction or landmark where possible.

The same kilometre value may occur on many different roads. The road number identifies which route the marker belongs to.

Divided roads have separate carriageways. Reporting the direction helps emergency services approach the correct side without making a long diversion.

Yes. Reporting the nearest marker can help breakdown and emergency services identify the affected road section more accurately.

Yes. The marker can help road authorities locate an obstruction, damaged barrier, animal, collision or other dangerous situation.

Normally not. It is a reference or identification device rather than a regulatory sign.

No. The applicable speed comes from general traffic rules and regulatory speed signs.

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

No. Passing a kilometre or hectometre marker does not normally begin or end a traffic regulation.

Yes. Road authorities use reference points to locate signs, barriers, bridges, defects, works and other infrastructure precisely.

Coordinates can be useful, but a road reference marker may be easier for road operators and emergency services to connect with the correct carriageway and road section.

Use the nearest visible marker together with the road number, direction, junctions and other identifiable features.

No. Do not stop in a live lane or another prohibited location. A passenger may note the marker, or the driver may read it after stopping somewhere safe during an actual emergency.

Normally not. Temporary traffic routes may move traffic away from the marker’s usual position, but the official road reference system generally remains unchanged.

Countdown markers are a series of signs that progressively indicate how close a driver is to an upcoming exit, junction, crossing or other important point.

The number of bars normally decreases as the driver approaches the indicated location. Depending on the country, the bars may represent fixed distances or simply successive stages of the approach.

They are commonly associated with motorway exits, major junctions and railway crossings, although their use and design differ between countries.

A traffic mirror is a convex roadside mirror that helps road users see around an obstruction or into a road with limited visibility.

They may be placed near intersections, narrow roads, bends, car-park exits, private driveways, tunnels or other locations where buildings, vegetation or road geometry obstruct the view.

A convex surface provides a wider field of view than a flat mirror, allowing more of the approaching road to be seen.

No. The reflected image is distorted, and objects normally appear smaller and farther away than they really are.

Not reliably. The curved image makes it difficult to estimate how fast another road user is approaching.

No. Distance can appear greater than it really is, so an approaching vehicle may reach the intersection sooner than expected.

Yes. Its position and viewing angle may leave parts of the road outside the reflected image. Small cyclists, motorcycles or pedestrians may also be difficult to notice.

No. It does not change priority. Drivers must continue to follow stop signs, give-way signs, traffic lights and the ordinary priority rules.

No. Another road user may be outside the reflected area, hidden by glare or too small to notice. Always check the road directly before proceeding.

Yes. The mirror does not replace the mandatory complete stop. Stop at the prescribed position, then use direct observation and the mirror as additional information.

Yes. You may proceed only when traffic with priority can continue without being forced to brake, stop or change direction.

Approach slowly, stop when required and scan the mirror for movement. Then look directly in both directions and continue only after confirming that the road is clear.

No. Alternate between the mirror and direct observation. The mirror should supplement rather than replace normal checks.

Yes. Rain, water droplets and spray may blur or partially obscure the reflected image.

Yes. Dew, condensation, frost, ice or snow may make the mirror difficult or impossible to use.

Yes. Sunlight may create glare or reflections that hide approaching road users.

Yes. Reflected headlights may make it difficult to determine the exact direction, distance or speed of an approaching vehicle.

Yes. Wind, impacts, vandalism, vibration or temperature changes may alter its orientation and make the reflected view inaccurate.

Do not rely on it. Proceed with additional caution and report the defect to the responsible road authority or property owner.

No. The applicable road or posted speed limit remains in force, but restricted visibility normally requires a lower approach speed.

No. Use the horn only where local law permits it and a warning is reasonably necessary to prevent danger.

Yes. It may help them observe approaching traffic, but they must also look directly and follow the applicable crossing and priority rules.

A mirror may generally be installed on private property with the owner’s permission, subject to local rules. Installing one on, above or beside a public road normally requires permission from the road authority.

No. Removing vegetation, relocating parking, improving the intersection layout or changing traffic circulation may provide a safer and more reliable solution.
