    ¿Es aconsejable que los conductores de motocicleta lleven guantes?

    Is it advisable for motorcycle riders to wear gloves?

    • ASólo en vías urbanas.Only on roads in built-up areas.
    • BSí.Yes.
    • CNo.No.
    Explanation

    Gloves protect the hands from cold and wind and prevent injuries in a fall, when you instinctively put your hands on the ground. In addition, since 1 October 2026, Article 118 of the General Traffic Regulations requires protective gloves to be worn on roads outside built-up areas.

    Question picture

    El pasajero que viaja en un cuadriciclo como el de la fotografía, ¿debe llevar casco?

    Must the passenger on a quadricycle like the one in the photograph wear a helmet?

    • ANo, solamente es obligatorio para las motocicletas y los ciclomotores.No, it is only compulsory on motorcycles and mopeds.
    • BNo, en los cuadriciclos solo es obligatorio para el conductor.No, on quadricycles it is only compulsory for the driver.
    • CSí, siempre.Yes, always.
    Explanation

    Drivers and passengers of quadricycles and quads must wear a protective helmet on all types of road (Article 118 of the General Traffic Regulations). They are exempt only if the vehicle has a protective structure and seat belts and this is stated in its documents, which is not the case with a quad like this one.

    Question picture

    El airbag, ¿sustituye al cinturón de seguridad?

    Does the airbag replace the seat belt?

    • ANo, es un sistema de seguridad complementario al cinturón.No, it is a safety system that complements the seat belt.
    • BSí, si circulamos dentro de poblado, pero no si lo hacemos fuera de él.Yes, if we are driving in a built-up area, but not outside one.
    • CSí, en los asientos delanteros que tengan airbag frontal.Yes, in front seats that have a front airbag.
    Explanation

    The airbag is a passive safety device that is not compulsory, unlike the seat belt, which is. In a frontal collision, if we do not wear the seat belt, even if the car has an airbag, we can suffer very serious injuries.

    Question picture

    Si conduce una motocicleta, ¿es aconsejable utilizar guantes?

    If you ride a motorcycle, is it advisable to wear gloves?

    • ASí; su uso es obligatorio en todo tipo de vías.Yes; they are compulsory on all types of road.
    • BSí, incluso en verano, para proteger las manos en caso de caída.Yes, even in summer, to protect your hands in a fall.
    • CNo, porque pueden dificultar la conducción.No, because they can make riding more difficult.
    Explanation

    Under Article 118.1(b) of the General Traffic Regulations (RGC) (as worded by Royal Decree 518/2026), protective gloves are compulsory for motorcycle riders and passengers on roads outside built-up areas, not on all types of road. Even so, it is advisable to wear them always, also in summer, because in a fall your hands are the first thing to hit the ground.

  7. Nº 307

    ¿Cuándo debe cambiarse el casco?

    When should you replace your helmet?

    • ACuando los colores pasen de moda.When its colours go out of fashion.
    • BCuando cambie de motocicleta.When you change motorcycle.
    • CCuando sufra algún golpe, ya que puede haberse dañado.When it takes a knock, because it may have been damaged.
    Explanation

    A knock can damage the internal structure of the helmet even if it looks fine on the outside, and then it no longer protects properly, so it must be replaced. Under Article 118.1 of the General Traffic Regulations (RGC) (as worded by Royal Decree 518/2026), motorcycle helmets must be approved under UNECE Regulation R22 and properly fastened.

  8. Nº 308

    Question picture

    ¿Cuál de las siguientes es una de las principales funciones del airbag en caso de accidente?

    Which of the following is one of the main functions of the airbag in an accident?

    • AEvitar el efecto submarino.Preventing submarining.
    • BReducir el riesgo de heridas en la cara producidas por fragmentos de cristal procedentes del parabrisas.Reducing the risk of facial injuries from pieces of glass from the windscreen.
    • CEvitar que la columna de dirección golpee al conductor.Stopping the steering column from hitting the driver.
    Explanation

    The airbag cushions the impact of the head and face against the steering wheel, the dashboard and pieces of glass from the windscreen. Submarining is prevented by a correctly positioned seat belt, not by the airbag.

  9. Nº 309

    Question picture

    El uso adecuado del casco implica que la correa de sujeción...

    Correct use of the helmet means that the chin strap...

    • Ano debe abrocharse.must not be fastened.
    • Bdebe llevarse correctamente abrochada, para que el casco cumpla eficazmente su función.must be correctly fastened, so that the helmet does its job effectively.
    • Cpuede llevarse desabrochada en vía urbana.may be left unfastened in built-up areas.
    Explanation

    The helmet only protects you if it stays on your head during the impact: with the strap unfastened or loose, it would fly off in the collision. That is why it must always be correctly fastened, including in town.

  10. Nº 310

    • Bsolo sobre el abdomen.only over the abdomen.
    • Csobre los huesos de las caderas, siempre por debajo del abdomen.over the hip bones, always below the abdomen.
    Explanation

    The lap belt must be worn low, over the hip bones and always below the abdomen. If it is over the stomach, in a crash it presses on soft organs and can cause internal injuries; the pelvis, on the other hand, can withstand the restraining force well.

  12. Nº 312

    Explanation

    Under Article 117.1 of the General Traffic Regulations (RGC), the driver and occupants of vehicles must wear a fastened seat belt both in and outside built-up areas, and taxi passengers have no exemption. Since Royal Decree 518/2026 (Art. 119.2), taxi drivers are not exempt in built-up areas either; in urban traffic, a taxi may only carry people shorter than 135 cm without a suitable restraint device if they sit in a rear seat.

The only exception is that, in urban traffic or urban areas of large cities, a taxi may carry people under 135 cm tall in a rear seat without a restraint system suited to their height and weight.

  18. Nº 318

    • CLos conductores de taxis en vías urbanas o interurbanas.Taxi drivers, in and outside built-up areas.
    Explanation

    The Traffic Regulations state that drivers who are reversing or parking are exempt from wearing a seat belt, because the seat belt can get in the way of doing these manoeuvres properly. The other two answers refer to roads outside built-up areas, and on these roads seat belts are always compulsory for all occupants of any type of vehicle.

    Under Article 119.2 of the General Traffic Regulations (RGC) (as worded by RD 518/2026), in built-up areas the seat belt exemption only covers drivers and passengers of vehicles on an emergency call; the old exemption for goods delivery drivers has been removed.

  32. Nº 332

    Explanation

    Children who are 1.35 m tall or less must sit in the rear seats of the vehicle, always using an approved restraint device suited to their height and weight. There are three exceptions in which children below that height may travel in the front seat: 1. When the vehicle has no rear seats. 2. When all the rear seats are already taken by children in the same situation, so it is impossible to fit all the child seats needed at that moment. 3. When it is not possible to fit child restraint systems in those seats. When children are taller than 1.35 m, they may sit in the front seat using the adult seat belt.

  34. Nº 334

    Explanation

    The seat belt must fit tightly against the body. If it is loose, in a collision the body slides under the lap belt (submarining) and serious injuries result; the lap belt must rest on the pelvic bones, not on the abdomen.

  36. Nº 336

    Question picture

    Si al pisar a fondo el freno de un vehículo que dispone de ABS, notamos unas vibraciones en el pedal, ¿qué haremos?

    • Blo mínimo posible y nunca más de 4 cm.as small as possible and never more than 4 cm.
    • Cla que resulte más cómoda para el conductor.whatever is most comfortable for the driver.
    Explanation

    For the head restraint to protect you, your head should be as close to it as possible; the gap should not be more than about 4 cm. If it is further away, in a rear-end collision the head travels further before it is supported and the risk of whiplash increases.

  38. Nº 338

    Is the seat belt compatible with the airbag?

    • ASí, ambos sistemas son compatibles.Yes, the two systems are compatible.

    • CA contramarcha, con la espalda hacia delanteRear-facing, with the baby's back towards the front of the car
