    Explanation

    When you brake sharply, there is a danger that the wheels will lock and you will lose control of the vehicle. To prevent this, there is ABS, an anti-lock safety system that stops the wheels from locking under hard braking. In an emergency stop, press the brake and clutch pedals at the same time, so that the engine does not stall and the anti-lock braking system (ABS) does not stop working. When the ABS comes into action, you will feel a slight vibration in the pedal, which is completely normal.

    • ALo más cerca posible.As close as possible.
    • B15 cm.15 cm.
    • C25 cm.25 cm.
    Explanation

    Explanation

    Under Article 119.2 of the General Traffic Regulations (RGC) (as worded by Royal Decree 518/2026), in built-up areas only drivers and passengers of vehicles on emergency duty are exempt from wearing a seat belt, so neither taxi drivers nor their passengers are exempt. 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.

  19. Nº 69

    • BÚnicamente será conveniente en verano.It is only advisable in summer.
    • CSí, siempre es conveniente.Yes, it is always advisable.
    Explanation

    Boots protect the foot and ankle in a fall and give a firm footing for working the rear brake and the gear lever, so they are worth wearing in every season. In addition, from 1 October 2026, Article 118 of the General Traffic Regulations requires closed footwear that covers the whole foot.

  22. Nº 72

    • Bseguridad activa.active safety.
    • Cseguridad pasiva.passive safety.

    • CMejorar la estética del automóvil.To make the car look better.
    Explanation

    A car's bodywork has several important functions, but its main one is to protect the occupants in a collision or other accident. It is designed to absorb and spread the energy of the impact, reducing the risk of serious injury. As well as its safety role, the bodywork also provides a strong structure that helps keep the vehicle intact in various situations, such as driving on uneven ground or in bad weather.

  24. Nº 74

    Question picture

    • CDe colores oscuros, para así no distraer a los conductores.in dark colours, so as not to distract drivers.
    Explanation

    Protective clothing for riding motorcycles should be in bright, eye-catching colours so that other road users can see the rider from far enough away. This increases safety, because other drivers can spot the motorcyclist more easily and take the necessary precautions. Dark colours can make the rider harder to see and distract drivers, so they are not recommended in this case.

  27. Nº 77

    Explanation

    Minors who are 1.35 m tall or less must sit in the rear seats of the vehicle, always using an approved restraint system suited to their height and weight. There are three exceptions in which minors 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 minors 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. If they sit in the front seat and the vehicle has a front airbag, they may only use rear-facing restraint systems if the airbag has been deactivated. When minors are taller than 1.35 m, they may sit in the front seat using the adult seat belt.

    • BNo, porque es obligatorio que todos los cascos tengan pantalla.No, because all helmets must have a face shield.
    • CNo, no es necesario.No, it is not necessary.
    Explanation

    When a motorcyclist rides with a helmet without a face shield or visor, it is advisable to wear safety glasses to protect the eyes, see the road better and avoid the dangers they may meet on it.

    Is it advisable for a motorcycle rider to wear boots?

    • ASí, siempre.Yes, always.
    • BÚnicamente en invierno.Only in winter.
    • CSolamente en verano.Only in summer.

    • BEl vehículo completoThe whole vehicle
    • CEl cuerpo del conductorThe rider's body

    • CEl cinturón no perderá eficacia, pero deberá ser reemplazado.The seat belt will not lose effectiveness, but it will have to be replaced.
    Explanation

    A loose or badly placed seat belt lets the body move before it is held: in a crash the occupant hits the inside of the vehicle or slides under the lap belt, and the belt itself can injure them. To be effective it must fit closely, with no slack or twists.
