1. Panamá

Panamá forma el estrecho puente terrestre entre Costa Rica y Colombia, con el mar Caribe al norte y el océano Pacífico al sur. Se circula por la derecha. Las condiciones de conducción van desde el tráfico denso de Ciudad de Panamá hasta largas carreteras interurbanas y rutas sinuosas por zonas tropicales y montañosas. Las fuertes lluvias estacionales son un riesgo importante: las inundaciones, los deslizamientos de tierra y los árboles caídos pueden bloquear las carreteras, especialmente durante periodos de lluvia intensa.

Panamá no tiene una viñeta nacional, pero varios corredores de alta velocidad alrededor de Ciudad de Panamá son de peaje; el Corredor Norte y el Corredor Sur de ENA utilizan el sistema de pago electrónico Panapass. Las normas nacionales establecen límites de velocidad según el tipo de vía, incluidos 40 km/h en calles residenciales, 100 km/h en carreteras y 120 km/h en autopistas, salvo que las señales indiquen otro límite. Las señales de tráfico siguen un sistema nacional y la información escrita aparece principalmente en español. Los turistas pueden conducir con un permiso válido de su país de origen durante un máximo de 90 días.

2. Paso a nivel

Un paso a nivel es un lugar donde una carretera o camino cruza vías férreas al mismo nivel. Puede estar protegido mediante barreras, luces de advertencia, señales acústicas, señales de tráfico o una combinación de estas medidas.

Los usuarios deben aproximarse con cuidado y no entrar nunca cuando se acerque un tren, estén activas las señales de advertencia o la salida esté bloqueada. Deben cruzar sin demora y nunca detenerse, esperar o quedar atrapados sobre las vías.

Paso a nivel
What is a railway crossing?

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

What is another name for a railway crossing?

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

How can you recognise a railway crossing?

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

What is the difference between a crossing with and without barriers?

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.

Must you always stop at a railway crossing?

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.

What do flashing red lights mean?

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

May you cross while a barrier is moving?

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.

May you drive around a closed barrier?

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

What does a warning bell mean?

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.

What does a flashing white light mean?

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.

What should you do at a crossing without lights or barriers?

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

May you cross immediately after a train has passed?

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

What if traffic ahead is blocking the exit?

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.

May you wait on the tracks?

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

May you overtake at a railway 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.

May you stop or park on a railway crossing?

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

Do the crossing signals apply to pedestrians and cyclists?

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

Should cyclists ride across the tracks at an angle?

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.

What should drivers of long vehicles check?

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.

What should drivers of high vehicles check?

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.

What should you do if the signals appear defective?

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

What should you do if your vehicle becomes stuck on the tracks?

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.

Is a railway crossing the same as tram tracks in the road?

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.

3. Marcha atrás

La marcha atrás consiste en conducir un vehículo hacia atrás. Se utiliza habitualmente al estacionar, salir de un espacio reducido o recolocar un vehículo cuando avanzar no es práctico.

Antes de dar marcha atrás, el conductor debe comprobar espejos y ángulos muertos, mirar cuidadosamente alrededor y asegurarse de que la zona posterior está libre. Debe hacerse lentamente y solo durante el tiempo necesario porque la visibilidad hacia atrás suele ser limitada.

Marcha atrás
What should you check before reversing?

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.

Who has priority when a vehicle is reversing?

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.

Should you reverse for a long distance?

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

4. Autobús

Un autobús es un vehículo a motor diseñado para transportar a varios pasajeros, normalmente por carretera como parte del transporte público, escolar, privado u otro servicio de pasajeros. Los autobuses suelen tener mayor capacidad que los turismos y pueden estar diseñados para pasajeros sentados, de pie o ambos.

Pueden aplicarse normas especiales sobre permiso de conducir, capacidad de pasajeros, límites de velocidad, cinturones, carriles bus, paradas y subida de pasajeros. La clasificación legal de autobuses y autocares y las normas aplicables varían entre países, por lo que conductores y pasajeros deben seguir las normas locales de tráfico.

Autobús
What is a bus?

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.

What is the difference between a bus and a coach?

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.

Do you need a special driving licence to drive a bus?

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

Can passengers stand on a bus?

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.

Must bus passengers wear seat belts?

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.

Can buses use bus lanes?

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.

Do buses always have priority when leaving a bus stop?

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.

Should you take extra care near a stopped bus?

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.

Do buses have special speed limits?

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.

Can a bus use a motorway?

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.

5. Policía

La policía es la autoridad pública responsable de hacer cumplir las leyes, mantener la seguridad pública y gestionar situaciones que pueden afectar al tráfico. En la circulación, los agentes pueden controlar vehículos, hacer cumplir las normas, investigar colisiones, dirigir el tráfico y responder a emergencias.

Los usuarios deben obedecer las instrucciones legales de los agentes u otro personal autorizado de control. Las indicaciones policiales pueden prevalecer temporalmente sobre semáforos, señales o la organización normal del tráfico, según la legislación local.

Policía
What is the role of police in road traffic?

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.

Must you obey a police officer directing traffic?

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.

What should you do if police signal you to stop?

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.

Can police direct you through a red traffic light?

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.

Can police check your driving documents?

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

Can police carry out alcohol or drug checks?

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

Can police temporarily close a road?

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

What should you do near police controlling an accident scene?

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.

What should you do when a police vehicle approaches with emergency signals?

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.

Can police order a parked vehicle to be moved?

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.

6. Bache

Un bache es un agujero o depresión en la superficie causado por desgaste, meteorología, agua, cargas repetidas o deterioro del pavimento. Puede variar mucho en tamaño y profundidad y desarrollarse gradualmente o empeorar tras heladas, lluvias intensas o tráfico repetido.

Los baches pueden afectar a dirección, frenada y estabilidad y dañar neumáticos, llantas o suspensión. Los conductores y motoristas deben observar la carretera, adaptar la velocidad y evitar maniobras bruscas o peligrosas.

Bache
What is a pothole?

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

How do potholes form?

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.

Why are potholes dangerous?

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.

What should you do when you see a pothole?

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.

Should you brake while driving through a pothole?

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.

Are potholes particularly dangerous for motorcycles?

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

Are potholes dangerous for cyclists?

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.

Can a pothole damage a car?

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

Should you swerve suddenly to avoid a pothole?

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.

Can a warning sign indicate potholes ahead?

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.

7. Camino

Un camino es una ruta relativamente estrecha destinada a peatones y, cuando esté permitido, a otros usuarios o vehículos pequeños. Los caminos pueden atravesar zonas urbanas, campo, parques, bosques o conectar otras carreteras, y pueden estar pavimentados o no.

Un camino no es necesariamente lo mismo que una acera o vía ciclista. Los usuarios que pueden utilizarlo dependen de su estatus legal, anchura, señales de tráfico y normas locales.

Camino
What is a path?

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

Is a path the same as a footpath?

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

Is a path the same as a cycle path?

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

Can cyclists use a path?

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.

Can motor vehicles use a path?

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.

Can a path be part of the public-road network?

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

Does a path need to be paved?

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

Can traffic signs restrict access to a path?

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

Who has priority when a path joins a larger road?

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

Can pedestrians and cyclists share a path?

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

Can a path cross another road?

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

Is every narrow route legally a path?

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.

8. Partículas

Las partículas, o material particulado (PM), son pequeñas partículas sólidas o gotas líquidas suspendidas en el aire. En el tráfico, las emisiones de partículas pueden proceder de gases de escape, desgaste de frenos, desgaste de neumáticos y desgaste de la superficie vial, además del polvo levantado por el paso de vehículos.

El material particulado suele clasificarse por tamaño. PM10 se refiere a partículas de hasta aproximadamente 10 micrómetros de diámetro, mientras que PM2.5 se refiere a partículas más finas de hasta aproximadamente 2,5 micrómetros. Las normas de emisiones, filtros de partículas y medidas de calidad del aire se utilizan para reducir la exposición a estos contaminantes.

Partículas
What are particulates?

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

What are PM10 and PM2.5?

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.

Where do traffic particulates come from?

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.

Are diesel vehicles a source of particulates?

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.

What is a particulate filter?

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.

Do petrol engines produce particulates?

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

Do electric vehicles produce particulates?

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

Are brake and tyre particles regulated?

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

Is particulate matter the same as CO2?

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.

How can vehicle particulate emissions be reduced?

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

9. Contaminación del aire

La contaminación del aire es la presencia de gases, partículas u otras sustancias en concentraciones que pueden perjudicar la salud humana, el medio ambiente o los ecosistemas. El tráfico contribuye mediante emisiones de escape y fuentes no relacionadas con el escape como desgaste de frenos, neumáticos y polvo de la carretera.

Entre los contaminantes importantes del tráfico se incluyen óxidos de nitrógeno, material particulado, monóxido de carbono y compuestos orgánicos volátiles. Algunos se emiten directamente y otros se forman en la atmósfera mediante reacciones químicas. Las normas de emisiones, tecnologías más limpias y medidas de gestión del tráfico ayudan a reducirlos.

Contaminación del aire
What is air pollution?

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

How does road traffic cause air pollution?

Vehicles produce pollutants through fuel combustion, exhaust systems, brake wear, tyre wear and road-surface interaction. Moving traffic can also resuspend dust already present on the road.

Which air pollutants are associated with road traffic?

Important traffic-related pollutants include nitrogen oxides, particulate matter, carbon monoxide and volatile organic compounds. Their relative importance depends on the vehicle, fuel and driving conditions.

What is nitrogen dioxide?

Nitrogen dioxide (NO2) is an air pollutant associated particularly with combustion processes and road traffic. High concentrations are commonly found near busy roads and densely trafficked urban areas.

What is particulate matter?

Particulate matter consists of tiny solid particles or liquid droplets suspended in the air. Road traffic can produce particles from exhaust, brakes, tyres and road surfaces.

Is CO2 the same as ordinary air pollution?

No. Carbon dioxide is primarily regulated as a greenhouse gas because of its contribution to climate change. Local air-quality pollution generally focuses on substances such as nitrogen dioxide, particulate matter, ozone and other pollutants that directly affect air quality and health.

Do electric vehicles cause air pollution?

Fully electric vehicles produce no combustion-engine exhaust emissions while driving, but they can still contribute to non-exhaust particulate emissions through tyres, brakes and road wear.

Can air pollution be worse near busy roads?

Yes. Concentrations of traffic-related pollutants can be higher close to heavily trafficked roads because many emissions occur close to ground level and near where people live and travel.

What is a low-emission zone?

A low-emission zone is an area where access by more polluting vehicles is restricted in order to reduce traffic-related air pollution. Access criteria may depend on factors such as fuel type, vehicle category and emission standard.

How can traffic-related air pollution be reduced?

Measures include cleaner vehicles, stricter emission standards, effective emission-control equipment, low-emission zones, public transport, cycling and walking, as well as traffic-management measures that reduce unnecessary congestion and emissions.

10. Hora punta

La hora punta es un periodo en el que las carreteras y redes de transporte público tienen una demanda especialmente elevada, normalmente porque mucha gente se desplaza al trabajo, colegio u otros destinos habituales. Suele producirse por la mañana y al final de la tarde o por la noche en días laborables.

Puede causar congestión, velocidades menores, viajes más largos y paradas frecuentes. Los conductores deben mantener una distancia segura, tener paciencia, anticipar cambios del tráfico y seguir cualquier medida temporal o dinámica de gestión.

Hora punta
What is rush hour?

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

When does rush hour occur?

Rush hour commonly occurs during the morning and late afternoon or evening on working days, but the exact times vary according to the city, road and local travel patterns.

Does rush hour always last one hour?

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

Why does traffic become congested during rush hour?

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

Should you increase your following distance in rush-hour traffic?

Yes. Leave sufficient distance to react to sudden braking and frequent changes in traffic speed. Avoid following another vehicle too closely even when traffic is moving slowly.

Should you frequently change lanes during congestion?

Unnecessary lane changes can create additional conflicts and may not significantly reduce journey time. Choose an appropriate lane, observe surrounding traffic and change lane only when it can be done safely.

Can speed limits change during rush hour?

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

What is a rush-hour lane?

A rush-hour lane is an additional traffic lane that can be opened during busy periods to increase road capacity. It may use a lane or shoulder that is closed to normal traffic at other times.

Can you use a rush-hour lane whenever traffic is congested?

No. Such a lane may only be used when traffic signals or signs indicate that it is open. Never assume that congestion alone permits its use.

How can you prepare for a journey during rush hour?

Check current traffic conditions and expected journey times, allow additional travel time and consider an alternative route, departure time or mode of transport where appropriate.

11. Código de circulación

Un código de circulación es un conjunto de leyes y normas que regulan cómo se utilizan las vías públicas. Establece reglas para conductores, ciclistas, peatones y otros usuarios y abarca materias como prioridad, velocidad, adelantamiento, estacionamiento, semáforos, señales y marcas viales.

Los códigos difieren entre países y a veces entre regiones. Se espera que todo usuario conozca y respete las normas aplicables donde circula, incluso cuando sean distintas de las de su país de origen.

What is a road code?

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

What does a road code regulate?

A road code can regulate subjects such as priority, speed, overtaking, turning, parking, traffic signals, road signs and road markings, as well as the responsibilities of different road users.

Are road codes the same in every country?

No. Although many traffic rules and signs are similar internationally, each country establishes its own traffic legislation and may apply different rules, signs, speed limits and requirements.

12. Canaleta de la calle

Una canaleta de la calle es un canal estrecho junto al borde de una carretera o calle que recoge agua de lluvia y la conduce hacia desagües u otros sistemas. Suele situarse entre la calzada y el bordillo y puede ser de hormigón, adoquines o formar parte de la superficie.

Es principalmente un elemento de drenaje y no un carril de tráfico. Los usuarios deben tener cuidado porque puede contener agua, residuos, aberturas de desagüe o superficies irregulares.

Canaleta de la calle
What is a street gutter?

A street gutter is a drainage channel along the edge of a road that collects rainwater and directs it toward drains or another drainage system.

Is a street gutter a traffic lane?

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

Why should cyclists take care near street gutters?

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

13. Bicicleta de carga

Una bicicleta de carga está diseñada para transportar mercancías, niños u otras cargas mayores que una bicicleta convencional. Puede utilizar una caja o plataforma delante o detrás del ciclista, un portaequipajes trasero alargado o un diseño de varias ruedas.

Puede ser impulsada completamente por el ciclista o disponer de asistencia eléctrica al pedaleo. Las dimensiones permitidas, capacidad de pasajeros, uso de vías ciclistas y límites de asistencia dependen de las normas locales de tráfico y vehículos.

Bicicleta de carga
What is a cargo bike?

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

What types of cargo bikes are there?

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

Can a cargo bike be electric?

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

Is an electric cargo bike still a bicycle?

It can be. If the electrical assistance remains within the applicable power and assistance-speed limits, the vehicle may remain legally classified as a bicycle. More powerful or faster models may belong to another category.

Can a cargo bike carry children?

Yes, when it is designed and equipped for passenger transport. Children should use the seats, restraints, foot protection or other safety equipment provided by the manufacturer and required by local law.

Can a cargo bike carry goods?

Yes. Transporting goods is one of its main purposes. Loads must be securely positioned and must not make the bicycle unstable, obstruct the rider's view or exceed applicable dimensional or weight limits.

Can a cargo bike use a cycle path?

This depends on its dimensions and legal classification. Ordinary-sized cargo bicycles generally follow bicycle rules, while unusually wide models may be excluded from certain cycle facilities.

Does a cargo bike need a driving licence?

Normally not when it remains legally classified as an ordinary bicycle or electrically assisted bicycle. Faster or more powerful vehicles may be subject to different licensing requirements.

Is a helmet compulsory on a cargo bike?

This depends on the country's bicycle rules and the vehicle's classification. A model legally classified as a faster motorised vehicle may have different helmet requirements from an ordinary cargo bicycle.

Should you ride differently when a cargo bike is heavily loaded?

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

Can a cargo bike tow a trailer?

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

Why should drivers take care around cargo bikes?

Cargo bikes can be longer, wider and heavier than ordinary bicycles and may need additional space when turning or stopping. Drivers should leave sufficient passing distance and avoid cutting across their path.

Is a forestry vehicle always a tractor?

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

What is a forestry tractor?

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

Can forestry vehicles travel on public roads?

Yes, when legally permitted and properly equipped. Registration, insurance, lighting, dimensions, speed and driving-licence requirements may apply before a forestry vehicle can use public roads.

Do you need a special driving licence for a forestry vehicle?

This depends on the vehicle classification, mass and country. Some countries have special agricultural or forestry vehicle licence categories, while other machines require ordinary car or heavy-vehicle licences.

Do forestry vehicles have special speed limits?

They may. The permitted speed can depend on the vehicle's construction speed, mass, road type and local traffic rules. Posted speed limits must also be respected.

Can forestry vehicles use motorways?

This depends on the country and vehicle classification. Agricultural and forestry vehicles are often restricted from high-speed roads, particularly when their construction speed is unsuitable for motorway traffic.

Why should drivers take care when passing a forestry vehicle?

Forestry vehicles can be large, slow, wide or equipped with projecting machinery. Reduce speed where necessary and overtake only when there is sufficient visibility and space.

Can a forestry vehicle tow a trailer?

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

Can forestry equipment extend beyond the normal width of the vehicle?

Some machinery or loads may make a forestry vehicle unusually wide or long. Where legal limits are exceeded, special markings, lighting, permits or escort arrangements may be required under local law.

What is a construction vehicle?

A construction vehicle is a vehicle or mobile machine used for construction, excavation, lifting, roadworks or transporting construction materials.

What are examples of construction vehicles?

Examples include excavators, wheel loaders, bulldozers, road rollers, mobile cranes, dump trucks and concrete mixers.

Is every construction vehicle legally the same type of vehicle?

No. A construction vehicle may legally be classified as a truck, mobile machine, special-purpose vehicle or another vehicle category depending on its design and use.

Can construction vehicles travel on public roads?

Yes, when the vehicle is legally permitted and suitably equipped for road use. Some machines are designed mainly for construction sites and may be subject to special restrictions when travelling on public roads.

Do you need a driving licence for a construction vehicle?

This depends on the vehicle category, mass, speed and local law. Heavy trucks, mobile cranes and specialised machines may require different licence categories.

Do construction vehicles have special speed limits?

They may. A vehicle's design speed, mass, tyres, suspension and legal classification can result in a lower permitted speed than that applying to ordinary cars.

Why should you take extra care near construction vehicles?

Construction vehicles can be large, slow and difficult to manoeuvre and may have significant blind spots. They may also turn, reverse or enter a construction site unexpectedly.

What do flashing amber lights on a construction vehicle mean?

Flashing amber lights generally warn other road users that the vehicle is working, moving slowly or creating an unusual obstruction or hazard. They do not normally give the vehicle the same priority as an emergency vehicle.

Can a construction vehicle be wider or heavier than an ordinary vehicle?

Yes. Some construction machinery exceeds normal vehicle dimensions or masses. Special permits, route restrictions, warning equipment or escorts may then be required.

What should you do when passing a construction vehicle?

Reduce speed where necessary and leave sufficient space. Be aware of blind spots, projecting equipment, wide turns and workers who may be present nearby.

16. Camión articulado

Un camión articulado es un conjunto formado por una cabeza tractora y un semirremolque utilizado principalmente para transportar mercancías. El semirremolque se acopla de modo que una parte importante de su peso es soportada por la tractora en lugar de únicamente por sus propias ruedas.

Se utiliza habitualmente para transporte de larga distancia y puede llevar contenedores, mercancías refrigeradas, líquidos, graneles u otras cargas.

Camión articulado
What is a semi-trailer truck?

A semi-trailer truck consists of a powered road tractor coupled to a semi-trailer primarily used to transport goods.

What is a semi-trailer?

A semi-trailer is a trailer designed so that part of the trailer and a significant part of its load are supported by the towing tractor.

What is the difference between a semi-trailer and an ordinary trailer?

An ordinary trailer generally supports its own weight through its axles, while a semi-trailer transfers a substantial vertical load to the tractor through its coupling.

How is a semi-trailer connected to the tractor?

The semi-trailer is normally connected through a kingpin and fifth-wheel coupling mounted behind the tractor cab.

Why are semi-trailer trucks called articulated vehicles?

The tractor and semi-trailer are connected by a pivoting coupling, allowing the two parts to turn relative to each other when the combination changes direction.

Do you need a special licence to drive a semi-trailer truck?

Yes. Heavy articulated trucks normally require a heavy-goods-vehicle licence that also authorises the driver to tow a heavy trailer or semi-trailer. The precise licence categories differ between countries.

Do semi-trailer trucks have lower speed limits?

They often do. Many countries impose vehicle-specific maximum speeds on heavy goods vehicles, particularly on motorways and other high-speed roads.

Why do semi-trailer trucks need more space to turn?

The semi-trailer's rear wheels follow a tighter path than the tractor's front wheels. Drivers therefore need additional space when turning, particularly at narrow intersections.

Why should you leave extra distance behind a semi-trailer truck?

Large trucks can restrict your view of traffic ahead and require considerable stopping distance. Keeping an appropriate following distance improves visibility and reaction time.

Why should you take care when driving beside a semi-trailer truck?

Large trucks have substantial blind spots around the cab and trailer. Avoid remaining beside the vehicle unnecessarily and be particularly careful when the truck is turning or changing lane.

17. Trolebús

Un trolebús es un autobús eléctrico que normalmente obtiene energía de cables aéreos mediante captadores montados en el vehículo. A diferencia de un tranvía, circula sobre ruedas normales y es dirigido por el conductor en lugar de estar guiado por raíles.

Se utiliza generalmente para transporte público de pasajeros y puede usar carriles bus, paradas y otras infraestructuras. Algunos trolebuses modernos también tienen baterías o sistemas auxiliares que permiten recorrer distancias cortas sin conexión a los cables.

Trolebús
What is a trolleybus?

A trolleybus is an electrically powered bus that normally receives electricity from overhead wires while travelling on ordinary road wheels.

Is a trolleybus the same as a tram?

No. A tram runs on rails and follows the path of its tracks. A trolleybus has ordinary tyres and is steered like a conventional bus.

Is a trolleybus an electric bus?

Yes. A trolleybus uses an electric motor, but unlike a battery-electric bus it traditionally receives most or all of its operating power from overhead electrical wires.

How does a trolleybus receive electricity?

Electrical current is normally collected from overhead wires through poles or another current-collection system mounted on the vehicle.

Can a trolleybus drive without overhead wires?

Some trolleybuses can. Modern vehicles may have batteries or auxiliary motors that allow limited operation away from the overhead wiring.

Can a trolleybus change lane?

Yes. Because it is steered rather than rail-guided, a trolleybus can move sideways within the range permitted by its overhead electrical connection and road layout.

Can trolleybuses use bus lanes?

Yes, where local rules permit. Trolleybuses operating public-transport services can normally use infrastructure reserved for authorised buses and public transport.

Do trolleybuses have priority when leaving stops?

This depends on the local traffic law. Some countries require other drivers to allow public-transport buses, including trolleybuses, to leave designated stops.

Should drivers slow down near a stopped trolleybus?

Yes. Passengers may be boarding, leaving or crossing the roadway. Drivers should approach carefully and give passengers sufficient space where required.

Does a trolleybus produce exhaust emissions?

A trolleybus operating entirely on electric power produces no combustion-engine exhaust emissions at the vehicle. Non-exhaust emissions from tyres, brakes and road wear can still occur.

18. Speed pedelec

Una speed pedelec es una bicicleta eléctrica de alta velocidad cuyo motor puede seguir proporcionando asistencia al pedaleo por encima del límite normal de una bicicleta eléctrica, normalmente hasta aproximadamente 45 km/h. Tiene pedales y está diseñada principalmente para asistir mientras se pedalea.

Por su mayor velocidad, puede recibir un tratamiento legal distinto al de una bicicleta ordinaria o eléctrica. Pueden aplicarse reglas especiales sobre edad mínima, permiso, casco, matriculación, seguro, uso de vías ciclistas y carreteras permitidas.

What is a speed pedelec?

A speed pedelec is an electrically assisted pedal cycle capable of providing motor assistance at higher speeds than an ordinary electric bicycle, commonly up to approximately 45 km/h.

What is the difference between a speed pedelec and an ordinary electric bicycle?

An ordinary electrically assisted bicycle normally stops providing motor assistance at a lower speed, commonly around 25 km/h. A speed pedelec can continue assisting the rider at higher speeds.

Do you still have to pedal a speed pedelec?

Normally yes. A speed pedelec is primarily designed to provide assistance while the rider pedals, although limited walking or starting assistance may also be provided.

Can a speed pedelec travel at 45 km/h?

Many speed pedelecs are designed to provide assistance up to approximately 45 km/h. The actual permitted speed must still comply with the local speed limit and traffic conditions.

Do you need a driving licence for a speed pedelec?

This depends on the country's legal classification. Some countries classify speed pedelecs similarly to mopeds and require an appropriate driving licence.

Is a helmet compulsory on a speed pedelec?

Helmet requirements vary between countries, but because speed pedelecs travel considerably faster than ordinary bicycles, specific helmet requirements commonly apply.

Does a speed pedelec need a licence plate?

In countries where speed pedelecs are classified as mopeds or another motor-vehicle category, registration and a licence plate may be compulsory.

Does a speed pedelec need insurance?

This depends on its technical characteristics and local law. Some jurisdictions require motor-vehicle liability insurance, while others exempt pedal-assisted speed pedelecs under specified conditions.

Can a speed pedelec use a cycle path?

This depends on the country, road speed limit and traffic signs. Speed pedelecs may be permitted, required or prohibited on particular cycle paths.

Can a speed pedelec use a motorway?

Speed pedelecs are generally unsuitable for motorways and are commonly prohibited where mopeds or low-speed vehicles are not permitted. Follow the local access rules.

Can you carry a passenger on a speed pedelec?

This depends on the vehicle's construction and local rules. Where passengers are permitted, the speed pedelec must be designed and equipped to carry them safely.

Is a speed pedelec the same as an electric moped?

No. A speed pedelec is primarily designed to provide pedal assistance, while an electric moped can normally propel itself without requiring the rider to pedal. Their legal classifications may nevertheless be closely related.

19. Vehículo de reparto

Un vehículo de reparto se utiliza para transportar y entregar mercancías, paquetes, suministros u otros artículos a viviendas, negocios u otros destinos. Puede ser una furgoneta, camión, turismo, motocicleta, bicicleta de carga u otro vehículo según el tipo y cantidad transportada.

Debe cumplir las normas ordinarias de su categoría y cualquier regla específica sobre carga y descarga, zonas de acceso restringido, estacionamiento, dimensiones y zonas de bajas emisiones. Tener permiso para hacer una entrega no autoriza automáticamente a detenerse o estacionar en cualquier lugar.

Vehículo de reparto
What is a delivery vehicle?

A delivery vehicle is a vehicle used to transport goods, parcels, supplies or other items to a particular destination.

Is a delivery vehicle always a van or truck?

No. Deliveries can be made using vans, trucks, cars, motorcycles, cargo bicycles or other suitable vehicles.

Can a delivery vehicle stop to load or unload goods?

Yes, where stopping is legally permitted. Many traffic systems distinguish genuine loading or unloading from ordinary parking when the vehicle remains only for the time necessary to perform the activity.

Can a delivery driver wait in a loading area?

A loading area is intended for active loading or unloading. Remaining there after the delivery activity has finished may constitute parking and may therefore violate the applicable restrictions.

Can delivery vehicles use restricted streets?

Sometimes. Traffic signs may provide an exception for deliveries, loading and unloading or local access. The driver must comply with any times, vehicle restrictions or other conditions shown.

Can delivery vehicles enter pedestrian zones?

Only where local rules or signs specifically allow delivery access. Access may be limited to certain hours, and vehicles may be required to travel at very low speed and give priority to pedestrians.

Can a delivery vehicle park on a pavement or cycle path while unloading?

Not automatically. Loading or unloading does not override general stopping restrictions or rules protecting pavements, cycle paths and other road users.

Can a delivery vehicle use hazard warning lights while illegally stopped?

No. Hazard warning lights warn other road users but do not make an otherwise prohibited stopping or parking position legal.

Can delivery vehicles be restricted by low-emission zones?

Yes. Vans and trucks may be subject to low-emission-zone requirements based on factors such as fuel type, vehicle category and emission standard.

Should drivers take extra care around delivery vehicles?

Yes. Delivery vehicles may stop frequently, reverse, open doors or move between the roadway and loading areas. Other road users should allow sufficient space and anticipate pedestrians or workers moving around the vehicle.

20. Motor al ralentí

Mantener el motor al ralentí significa dejarlo funcionando mientras el vehículo está detenido y el motor no se utiliza para moverlo. Puede ocurrir al esperar, estacionar, cargar o descargar o antes de iniciar un viaje.

El ralentí innecesario consume combustible y produce emisiones de escape, contaminación del aire y ruido. Muchos países o autoridades locales restringen el ralentí prolongado o innecesario, aunque puede haber excepciones cuando el motor sea necesario por seguridad, equipo técnico u otro fin necesario.

What is idling?

Idling means keeping a vehicle's engine running while the vehicle remains stationary and the engine is not being used to propel it.

Why should unnecessary idling be avoided?

Unnecessary idling uses fuel, produces exhaust emissions and creates noise without moving the vehicle.

Is idling illegal everywhere?

No. Rules differ between countries and local authorities. Some prohibit unnecessary idling generally, while others restrict it only in particular locations or circumstances.

Does an idling engine still produce exhaust emissions?

Yes. A combustion engine continues to produce exhaust gases while running even though the vehicle is not moving.

Does idling use fuel?

Yes. A combustion engine consumes fuel while it remains running, even when the vehicle is stationary.

Should you leave the engine running while waiting for someone?

Where it is safe and legal to switch the engine off, unnecessary prolonged idling should generally be avoided. Local rules may specifically require the engine to be switched off.

Is waiting at a red traffic light the same as parking with the engine idling?

No. A vehicle temporarily prevented from moving by traffic conditions is different from a vehicle voluntarily parked or waiting. The rules concerning engine shutdown may therefore differ.

Can an engine remain running when vehicle equipment needs power?

Some laws provide exceptions when the engine is genuinely required to operate refrigeration, hydraulic equipment, emergency equipment or another essential system. The precise exceptions depend on local law.

Should you rev the engine while stationary?

Unnecessary engine revving should be avoided because it increases noise, fuel consumption and emissions. It may also be specifically prohibited by local traffic or noise regulations.

Do electric vehicles idle?

Not in the conventional combustion-engine sense. An electric vehicle can remain stationary while switched on without an internal-combustion engine running, although electrical systems such as heating or air conditioning may still consume energy.

21. Grúa

Una grúa es un vehículo especializado utilizado para recuperar, remolcar, elevar o transportar vehículos averiados, dañados, mal estacionados o incapaces de continuar normalmente. Puede utilizar equipos de elevación, cabrestante, elevador de ruedas o plataforma de carga.

Como la recuperación puede realizarse junto a tráfico en movimiento, las grúas suelen utilizar luces de advertencia y otros equipos de seguridad. Los conductores que se aproximen deben reducir la velocidad cuando sea necesario, dejar espacio suficiente y seguir cualquier control temporal o instrucción autorizada.

What is a tow truck?

A tow truck is a specialised vehicle designed to recover, tow, lift or transport vehicles that are disabled, damaged or otherwise need to be removed.

How can a tow truck move another vehicle?

Tow trucks may use a wheel lift, lifting arm, winch, towing equipment or loading platform. The recovery method depends on the type and condition of the vehicle being moved.

What is a flatbed tow truck?

A flatbed tow truck carries the recovered vehicle on a loading platform rather than leaving some of its wheels on the road.

When is a tow truck used?

A tow truck may be used after a breakdown, collision, vehicle defect or other situation in which a vehicle cannot safely continue or must be removed.

Why do tow trucks use flashing warning lights?

Warning lights alert other road users that the tow truck is working, moving slowly or creating an unusual roadside hazard. The meaning and permitted colour of the lights depend on local law.

Do flashing lights give a tow truck emergency-vehicle priority?

Not necessarily. Warning lights used for vehicle recovery usually indicate a hazard rather than giving the tow truck the same legal priority as a police car, ambulance or fire vehicle.

Can any vehicle tow a broken-down car?

This depends on the local towing rules and equipment. Emergency towing may be permitted under limited conditions, while professional recovery vehicles can use specialised equipment designed for the task.

Can a tow truck recover a vehicle from a motorway?

Yes, where authorised and suitably equipped. Motorway recovery may be subject to special safety procedures because of the high traffic speeds and restricted stopping areas.

Should you slow down when passing a working tow truck?

Yes. Recovery personnel may be working close to live traffic and vehicles or equipment may occupy part of the roadway. Reduce speed where necessary and leave sufficient space.

Can a tow truck recover heavy trucks and buses?

Yes, if it is designed and rated for the vehicle concerned. Heavy recovery vehicles use specialised lifting and towing equipment for trucks, buses and other large vehicles.

22. Tracción a las cuatro ruedas

La tracción a las cuatro ruedas, abreviada como 4WD o 4x4, es un sistema capaz de transmitir potencia a las cuatro ruedas. Puede proporcionar tracción adicional sobre nieve, barro, grava, arena o terreno irregular.

Los sistemas pueden funcionar permanentemente o activarse automática o manualmente cuando se necesita más tracción. Pueden mejorar la capacidad de avanzar sobre superficies difíciles, pero no eliminan la necesidad de neumáticos adecuados, velocidad segura y frenada y dirección cuidadosas.

Tracción a las cuatro ruedas
What is four-wheel drive?

Four-wheel drive is a drivetrain system that can send power to all four wheels of a vehicle rather than only the front or rear wheels.

What does 4x4 mean?

4x4 normally indicates a vehicle with four wheels of which all four can be driven by the powertrain.

Is four-wheel drive the same as all-wheel drive?

The terms 4WD and AWD are sometimes used interchangeably, but manufacturers often use them for different types of system. Traditional 4WD systems commonly provide selectable driving modes, while AWD systems often distribute power automatically.

Does four-wheel drive improve traction?

Yes. Sending power to more wheels can improve traction when accelerating on snow, mud, gravel, sand or other low-grip surfaces.

Does four-wheel drive shorten braking distance?

Not automatically. Braking performance depends primarily on the tyres, road surface, speed, braking system and vehicle condition. Four-wheel drive should not encourage a driver to travel faster on slippery roads.

Does a four-wheel-drive vehicle still need suitable tyres?

Yes. The tyres provide the contact between the vehicle and road. Four-wheel drive cannot compensate for tyres that are unsuitable, excessively worn or incorrectly inflated.

Can four-wheel drive help in snow?

Yes. It can improve the ability to move away and climb on snow-covered roads, but safe braking and cornering still depend heavily on tyre grip and appropriate speed.

Can a four-wheel-drive vehicle drive off-road?

Some 4x4 vehicles are designed for off-road use, but four-wheel drive alone does not make every vehicle suitable for difficult terrain. Ground clearance, tyres, suspension and the drivetrain design are also important.

Can you use four-wheel drive on dry roads?

This depends on the type of drivetrain. Permanent or automatic systems are designed for normal road use, while some selectable 4WD systems should only be engaged under particular conditions. Follow the manufacturer's instructions.

Does four-wheel drive increase towing capacity?

It can improve traction when towing, but the legally and technically permitted trailer mass is determined by the vehicle's approved towing limits and local regulations, not simply by the presence of four-wheel drive.

23. Bicicleta

Una bicicleta es un vehículo de dos o más ruedas impulsado principalmente por el usuario mediante pedales o manivelas. Se utiliza para transporte, ocio, deporte y transporte de pequeñas cargas o pasajeros cuando está adecuadamente equipada.

Algunas tienen un motor eléctrico que asiste mientras se pedalea. Que siga clasificándose legalmente como bicicleta depende de potencia, velocidad de asistencia y normas locales. Los ciclistas deben respetar las normas, señales, semáforos y requisitos aplicables.

What is a bicycle?

A bicycle is a wheeled vehicle primarily propelled by the rider using pedals or hand cranks.

Is an electric bicycle still a bicycle?

It can be. Electrically assisted bicycles that remain within specified power and assistance-speed limits are commonly treated as bicycles. Faster or more powerful vehicles may be classified differently.

Where should cyclists ride?

Cyclists should use cycle paths, cycle lanes or the roadway according to the local traffic rules and signs. The required position varies between countries and road types.

Must cyclists use a cycle path?

This depends on the country and type of cycle facility. Some cycle paths are compulsory, while others are optional.

Do bicycles need lights?

Yes, when required by local law. Bicycles commonly need a white or yellow light at the front and a red light at the rear during darkness or poor visibility.

Do bicycles need brakes?

Yes. A bicycle used on public roads must have an effective braking system appropriate to its design and local technical requirements.

Is a bicycle helmet compulsory?

This varies between countries. Some require helmets for all cyclists or particular age groups, while others recommend helmets without making them compulsory.

Can a bicycle carry a passenger?

Yes, where the bicycle is appropriately equipped and local law permits it. A passenger should use a proper seat and any other required safety equipment.

Can cyclists ride side by side?

This depends on local law and the road conditions. Many countries allow two cyclists to ride beside each other in certain circumstances but require single-file riding when necessary for safety or traffic flow.

Is someone walking a bicycle still a cyclist?

In many traffic systems, a person who dismounts and walks the bicycle by hand is treated as a pedestrian. The exact legal definition depends on local law.

24. Equipamiento de motocicleta

El equipamiento de motocicleta incluye el equipo de protección del conductor y pasajero y el equipamiento de seguridad instalado en la motocicleta. Suele incluir casco, ropa protectora, guantes, botas y protección ocular, mientras que la motocicleta requiere luces, frenos, espejos, neumáticos e indicadores según la legislación local.

Los elementos legalmente obligatorios varían entre países y categorías. Los usuarios deben asegurarse de que tanto su equipamiento protector como la motocicleta sean adecuados, se utilicen correctamente y estén en condiciones seguras.

Equipamiento de motocicleta
What equipment should a motorcyclist use?

Motorcyclists should use appropriate protective equipment, commonly including a helmet, gloves, protective jacket and trousers, and footwear that protects the feet and ankles.

Is a motorcycle helmet compulsory?

Helmet requirements depend on local law, although approved motorcycle helmets are compulsory in many countries. The helmet should fit correctly and be used in a way that preserves its protective function.

Why is protective motorcycle clothing important?

Protective clothing can reduce injuries caused by impact, abrasion and contact with the road surface. Purpose-designed motorcycle clothing may also include impact protectors for vulnerable parts of the body.

Why should motorcyclists wear gloves?

Gloves help protect the hands and wrists against abrasion, weather and impact and can also improve grip on the motorcycle controls.

Why are motorcycle boots important?

Suitable boots provide protection for the feet and ankles and can reduce injuries caused by impact, abrasion or the motorcycle falling onto the rider.

Does a motorcycle passenger need protective equipment?

Yes. Passengers are exposed to many of the same risks as riders and should use appropriate protective equipment. Local law may require the passenger to wear the same helmet and clothing as the rider.

What safety equipment must a motorcycle have?

A road-legal motorcycle normally requires functioning brakes, tyres, lights, reflectors, mirrors, a horn and other prescribed equipment. Exact technical requirements vary between countries and motorcycle categories.

Should motorcycle lights be checked before riding?

Yes. Check that the headlight, rear light, brake light and direction indicators work correctly where fitted or required. Motorcycle visibility is especially important because motorcycles can be difficult for other road users to detect.

Should motorcycle tyres be checked regularly?

Yes. Check tyre condition, tread and pressure regularly. Because motorcycles rely on two relatively small tyre contact areas, damaged or incorrectly inflated tyres can significantly affect stability, steering and braking.

Should motorcycle equipment be checked before every journey?

A brief check of the tyres, brakes, lights, controls, mirrors and general condition of the motorcycle can help identify problems before riding. Protective equipment should also be correctly fitted and in usable condition.

25. Vía férrea

Una vía férrea es un par de raíles utilizado para guiar tranvías, trenes u otros vehículos ferroviarios. Puede discurrir junto a una carretera, cruzarla o estar integrada directamente en la calzada.

Los usuarios deben tener especial cuidado porque los vehículos ferroviarios no pueden esquivar obstáculos y necesitan una distancia considerable para detenerse. Deben respetar prioridades, semáforos, señales y reglas de cruce y evitar bloquear las vías.

Vía férrea
What is a track?

A track consists of rails that guide trams, trains or other rail vehicles. Tracks may be separated from ordinary traffic or incorporated into a road.

Can tram tracks run along an ordinary road?

Yes. Tram tracks may be embedded in the carriageway and share part of the road with other traffic, depending on the local road layout and traffic rules.

Who has priority when a road crosses tram tracks?

The applicable priority rules vary between countries, but rail vehicles commonly receive special priority because they cannot leave their tracks. Always obey traffic lights, signs and local rules.

Can you drive on tram tracks?

This depends on the road layout and local regulations. Tracks incorporated into an ordinary traffic lane may sometimes be used by other vehicles, while reserved tram tracks or separate railway tracks may not.

Can you stop or park on railway or tram tracks?

You should never stop or park where your vehicle would obstruct a rail vehicle. Local traffic law may specifically prohibit stopping or parking on or close to tracks.

Why are tracks dangerous for cyclists and motorcyclists?

Wheels can slip on wet rails or become trapped in the groove beside a rail. Riders should cross tracks carefully and, where possible, at an angle that reduces the risk of a wheel following the rail groove.

Should you follow a tram closely?

No. Maintain sufficient distance so that you can react safely if the tram stops, passengers enter the roadway or traffic conditions change.

Can pedestrians cross tram tracks?

Yes, where crossing is permitted, but pedestrians should carefully check for approaching rail vehicles and obey pedestrian lights and crossing restrictions.

Is a tram track the same as a railway level crossing?

No. Tram tracks can be incorporated directly into a street or carriageway. A railway level crossing is a specific place where a road or path crosses railway tracks, usually with dedicated warning signs or signals.

What should you do if traffic stops while you are crossing tracks?

Do not enter a track crossing unless there is enough space to clear it completely. Never deliberately stop where a tram or train could be blocked.
