Traffic signsUnited Kingdom

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

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

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

Check behind and around the vehicle for pedestrians, cyclists, other vehicles and obstacles. Use mirrors and cameras where available, but also look directly because monitoring systems can have blind spots.

In many countries, reversing is treated as a manoeuvre and the reversing driver must give way to other road users. The exact legal requirements depend on national traffic rules.

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

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

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

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

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

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

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

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

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

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

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

A verge is an area alongside a roadway, generally between the roadway and a ditch, embankment, property boundary or other roadside feature.

No. A verge is normally a separate part of the road environment alongside the roadway.

No. A pavement or sidewalk is specifically intended for pedestrians, while a verge may primarily form the roadside margin and may not be paved or comfortably walkable.

No. A cycle path is specifically designated for cyclists and other permitted users. A verge has a different function and legal status.

Yes. A level verge lies approximately at the same height as the roadway and may consist of grass, gravel, soil or another surface.

Yes. A raised verge lies above the level of the roadway and is normally clearly distinguishable from it.

Yes, where local rules permit or require it. A verge may provide a walking route where no suitable pavement or dedicated pedestrian facility is available.

This depends on the country, type of verge and available cycling facilities. Local traffic law may permit cyclists to use a suitable verge in particular circumstances.

Normally vehicles use the roadway, but local rules may permit temporary use of a suitable verge for purposes such as passing, meeting oncoming traffic or accessing property.

This depends on local traffic law, the type of verge and the location. Where verge parking is permitted, sufficient space may have to remain available for pedestrians and other road users.

No. A soft or uneven verge can provide significantly less grip than the roadway and may affect steering or vehicle stability. Reduce speed and return to the roadway safely when possible.

Yes. Verges commonly provide space for traffic signs, lighting, drainage, utility equipment, vegetation and other roadside infrastructure.

Traffic calming is the use of road-design measures to reduce vehicle speeds and create safer conditions for pedestrians, cyclists and other road users.

Common measures include speed humps, raised crossings, chicanes, narrowed carriageways, traffic islands and redesigned intersections.

Traffic calming is commonly used in residential areas, school areas, town centres and other places with significant pedestrian or cyclist activity.

Equestrian refers to horse riding and, in a traffic context, particularly to people travelling on horseback or using designated horse-riding routes.

Depending on local rules, riders may use roads, bridleways, paths or routes specifically designated for horse riding.

Drivers should slow down, leave plenty of space and pass calmly, avoiding sudden acceleration, horn use or other actions that could frighten the horse.

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

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

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

A city limit marks the boundary of a city, town, village, locality or municipality. On roads, it is often indicated by a place-name or boundary sign.

No. A city-limit or locality sign may simply identify a place or administrative boundary. A legally defined built-up area can use a different sign or definition.

No. In some countries a locality or boundary sign has consequences for traffic rules, while in others it mainly identifies the place. Drivers must follow the traffic signs and rules that apply in that country.

Not always. Some signs indicate an administrative municipal boundary, while others identify a city, town, village or locality without exactly following the municipality's legal boundary.

A city limit identifies the boundary of a named place or administrative area. A built-up area is a traffic-law concept that may affect rules such as default speed limits. The two boundaries can coincide, but they do not have to.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A dip is a short depression in the road surface where the road falls and then rises again.

A dip can reduce visibility, affect vehicle stability and hide road users or obstacles. Water may also collect in the lowest part of the depression.

Approach at a suitable speed, keep the vehicle under control and be prepared for hazards that may not be visible until you enter or leave the dip.

A tram lane is a lane or track area intended primarily for trams and other authorised public-transport vehicles.

It depends on the country and the signs provided. Some tram lanes are exclusively reserved for trams, while others may also be used by buses, taxis, cyclists or other authorised vehicles.

Usually, where permitted and necessary. Drivers may be allowed to cross tram tracks to turn, enter a property or cross an intersection, but they must follow the applicable signs and priority rules.

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

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

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

A bus is a motor vehicle designed to transport a relatively large number of passengers. It may be used for public transport, school transport, private services or other passenger transport.

A bus is commonly designed for frequent passenger boarding and may allow standing passengers, while a coach is generally designed for longer journeys with passengers seated. Exact legal definitions vary between countries.

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

Only when the vehicle is designed and approved to carry standing passengers. Coaches and other vehicles designed exclusively for seated passengers must not be used beyond their approved passenger configuration.

Where seat belts are provided and local law requires their use, passengers must wear them correctly. Urban buses designed for standing passengers may have seating positions or operating conditions that differ from coaches.

Yes, where permitted. Bus lanes are commonly reserved for public transport buses, although local signs may also allow taxis, bicycles or other specified vehicles to use them.

No. Some countries require other drivers to give way to buses leaving designated stops, particularly in urban areas, while others apply the normal merging rules.

Yes. Passengers may be boarding, leaving or crossing the road near the bus. Reduce speed where necessary and watch carefully for pedestrians emerging from behind or in front of the vehicle.

They can. Some countries impose lower maximum speeds on buses than on passenger cars, particularly on high-speed roads. Different limits may apply to buses and coaches.

Yes, normally. Buses that satisfy the applicable construction and access requirements may use motorways, but they must obey any vehicle-specific speed limits, lane restrictions and other local rules.

Police help enforce traffic laws, manage traffic, investigate collisions and respond to dangerous situations. They may also carry out roadside checks and direct road users.

Yes. Lawful directions given by an authorised police officer must be followed. In many countries, those directions take precedence over traffic lights, road signs and normal priority rules.

Slow down, follow the officer's directions and stop at a safe location as instructed. Do not make sudden movements or continue driving unless directed to do so.

Yes, where authorised by local law. A police officer controlling traffic may instruct road users to proceed even when a traffic light or sign would normally require them to stop.

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

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

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

Reduce speed, remain alert and follow all directions. Do not enter a closed area or interfere with emergency personnel, and leave sufficient space for emergency vehicles.

Follow the local rules for priority vehicles. Drivers generally have to make sufficient space, give way and stop where necessary so that the emergency vehicle can pass safely.

Yes, where local law permits it. Police or another authorised authority may require a vehicle to be moved when it obstructs traffic, creates danger or must be removed for operational reasons.

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

This depends on the local traffic rules and warning signals being used. Ambulances responding to emergencies commonly use flashing lights and a siren to indicate that other road users must make way.

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

Not necessarily in your exact position. Move or stop in a way that creates a safe passage without blocking an intersection, pedestrian crossing or another part of the road needed by the ambulance.

Emergency vehicles may be allowed to pass a red light during an urgent response under special legal conditions. The precise rules differ between countries, and the ambulance driver must still take appropriate precautions.

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

Yes, when responding to an emergency and legally permitted to do so. Other road users should create space and keep emergency corridors or access routes clear where required.

You should not use the passage created for an ambulance as a way to bypass congestion. Maintain a safe distance and continue to obey the normal traffic rules.

No. The use of warning lights and sirens depends on the urgency of the mission and local regulations. An ambulance transporting a patient does not necessarily need to use emergency signals throughout the journey.

Reduce speed and remain alert. Medical personnel, patients or other emergency workers may be entering the road, and the ambulance may need to move unexpectedly.

A roadway, or carriageway, is the part of a road primarily intended for the movement of vehicles.

No. The complete road can also contain pavements, cycle paths, verges, parking areas, central reservations and other sections that do not form part of the roadway.

No. A traffic lane is a portion of the roadway intended for a line of moving vehicles. A roadway may contain one or several lanes.

Yes. A roadway may carry two-way traffic or may be restricted to traffic travelling in only one direction.

Normally no when it is legally designated as a separate cycle facility. It may form part of the wider road while remaining separate from the roadway.

No. A pavement or sidewalk is normally a separate part of the road intended primarily for pedestrians.

Yes. A designated parking strip or parking area may form a separate part of the road alongside the roadway.

Drivers normally use the roadway and the traffic lanes intended for their direction of travel, except where another part of the road is specifically provided or permitted for their vehicle category.

Yes. Cyclists may or must use the roadway when permitted by local rules, particularly where no applicable cycle facility is available or compulsory.

Pedestrians may sometimes use the roadway when no suitable pedestrian facility is available, subject to the local rules governing their position and direction of travel.

Yes. Continuous or broken longitudinal road markings commonly divide a roadway into individual traffic lanes and regulate how drivers may move between them.

Yes. The roadway, cycle paths, pavements, parking areas and other sections may each have different permitted users and traffic rules.

A street is a road in a built-up or developed area that commonly provides access to buildings, properties and activities along it.

Not exactly. Road is a broader term that can include motorways, rural roads and other routes. A street is normally associated with a built-up area and access to properties or activities.

No. The roadway or carriageway is the part primarily intended for vehicle traffic. A street can also contain pavements, cycle facilities, parking areas and other infrastructure.

Yes. Pedestrians normally use the pavement, sidewalk or other pedestrian facilities provided along the street and cross the roadway according to the applicable crossing rules.

Yes. Cyclists may use cycle paths, cycle lanes or the roadway according to the local traffic rules and infrastructure.

Yes. A street may be restricted to vehicles travelling in one direction, while signs may sometimes allow particular road users such as cyclists to travel in both directions.

Yes. Streets may form pedestrian zones, school streets, play streets or other restricted areas where motor-vehicle access is prohibited or limited.

No. The applicable speed depends on the country, location, type of street and traffic signs. Special lower limits commonly apply in residential, school or pedestrian-oriented areas.

Yes, where parking is permitted. Drivers must respect parking signs, road markings and general restrictions concerning crossings, intersections, driveways and other protected locations.

Yes. Streets may carry buses, trams or other public transport and can include dedicated lanes, tracks and passenger stops.

Yes. A cycle path may run along a street while remaining a separate part of the road from the ordinary roadway.

Drivers should expect frequent interaction with pedestrians, cyclists, parked vehicles, intersections, driveways and public transport and should adapt their speed and observation accordingly.

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

Potholes can develop through a combination of water, temperature changes, traffic loads and deterioration of the road material. Cracks can gradually expand until pieces of the surface break away.

A pothole can cause a vehicle to change direction suddenly, lose stability or suffer tyre, wheel or suspension damage. Deep potholes can present a particularly serious hazard at higher speeds.

Reduce speed when necessary, maintain control of the vehicle and avoid abrupt steering or braking. Only move around the pothole when this can be done safely without endangering other road users.

If possible, reduce your speed before reaching the pothole. Sudden heavy braking or steering while passing over a damaged surface can make the vehicle less stable.

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

Yes. Bicycle wheels can be strongly affected by deep holes or sharp edges, particularly when the cyclist has little time or space to avoid the hazard.

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

No. A sudden evasive movement may create a greater danger by bringing the vehicle into conflict with cyclists, pedestrians, oncoming traffic or vehicles in another lane.

Yes. Depending on the country's traffic-sign system, an uneven-road or general-danger warning sign may be used where poor road conditions create a significant hazard.

A private road is a road whose access and use are controlled by a private owner or organisation rather than being freely available as part of the ordinary public-road network.

This depends on the owner's access rules. Use may be limited to residents, visitors, customers, employees, delivery vehicles or other authorised persons.

Yes. A privately owned road may be made available to general public traffic. In some legal systems, this can affect which traffic rules apply to it.

No. A private road is one particular type of private property. Private property can also include buildings, gardens, yards, car parks and other land.

Generally yes, subject to applicable legal rights and restrictions. Access can be controlled by gates, barriers, signs or permits.

Not necessarily. Their legal effect depends on the country, road status and authority under which they were installed.

This depends on whether the road falls within the scope of the country's road-traffic legislation. The owner may also impose additional private speed restrictions.

Only when the owner's rules and applicable law permit it. Parking may be reserved, restricted or prohibited.

Depending on local law, the owner or operator may be able to arrange removal of vehicles that are unauthorised, abandoned or obstructing access.

Approach the public road carefully and follow the applicable rules for joining traffic from private property or an access road. Drivers commonly have to give way to road users already using the public road.

Yes, where their duties and local law permit it. Access may be necessary for fire, medical, police or rescue operations.

It determines whether ordinary road-traffic rules, insurance requirements, traffic signs and enforcement powers apply in the same way as they do on a public road.

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

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

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

This depends on the legal status, width and signs applying to the path. Some paths permit cyclists, while others are reserved for pedestrians or particular users.

This depends on local law. Some paths prohibit motor vehicles entirely, while narrow vehicles may be permitted on other paths unless traffic signs restrict access.

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

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

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

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

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

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

No. Its legal classification depends on the definitions and regulations of the country concerned. A narrow route might instead be a footpath, cycle path, private access road or another type of facility.

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

PM10 refers to particles with a diameter of up to approximately 10 micrometres. PM2.5 refers to finer particles with a diameter of up to approximately 2.5 micrometres.

Road traffic can produce particles through engine exhaust, brake wear, tyre wear and road-surface wear. Passing traffic can also resuspend dust already present on the road.

Yes. Combustion in diesel engines can produce very small soot particles. Modern diesel vehicles commonly use particulate filters to capture a large proportion of these exhaust particles.

A particulate filter is an exhaust-treatment device designed to trap particulate matter produced by an engine. Diesel particulate filters are commonly known as DPFs.

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

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

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

No. Particulate matter consists of tiny airborne particles, while carbon dioxide is a gas. They are different types of vehicle emissions and are regulated for different environmental reasons.

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