8. Nº 8

   

   Si circula con su turismo durante la noche por una vía interurbana insuficientemente iluminada y a menos de 40 km/h, ¿qué alumbrado deberá llevar encendido?

   If you are driving your car at night on a poorly lit road outside a built-up area at less than 40 km/h, which lights must you have on?

   • AEl de largo alcance.Main beam.
   • BEl de corto alcance.Dipped headlights.
   • COpcionalmente el de largo o corto alcance.Optionally, main beam or dipped headlights.
   Explanation

   Vehicles fitted with main beam must use it when driving at more than 40 km/h: - between sunset and sunrise, on poorly lit roads outside built-up areas; - at any time of day, in tunnels, underpasses and stretches of road covered by the 'Tunnel' sign that are poorly lit. However, dipped headlights must be used by: - vehicles that do not have main beam; - vehicles driving with main beam that could dazzle other road users. When driving at no more than 40 km/h, you can use dipped headlights or main beam. It is prohibited to use main beam when the vehicle is stopped, parked or in a built-up area. In this case, as you are not driving at more than 40 km/h, main beam is optional, not compulsory.

9. Nº 9

   Explanation

   Under Article 106.2 of the RGC, the rear fog light is only used in especially unfavourable conditions, such as thick fog, very heavy rain, heavy snowfall or dense clouds of dust or smoke. If visibility is only reduced, dipped headlights, main beam or the front fog lights are enough.

    Explanation

    Main beam is used outside built-up areas on roads that are not lit well enough, including motorways (autopistas) and poorly lit tunnels (Article 100.1 of the General Traffic Regulations, RGC). In built-up areas you use dipped headlights even if the road is poorly lit (Article 101.1), and you must switch to dipped headlights whenever you might dazzle someone (Article 102.1).

Since 1 January 2026, this device is the V-16 flashing warning beacon, placed on the highest part of the vehicle.

15. Nº 15

    En una travesía, ¿está permitido circular con las luces largas encendidas?

    In a travesía (stretch of road through a town), are you allowed to drive with main beam on?

    • BSí, en travesías poco iluminadas.Yes, in poorly lit travesías.
    • CSólo si se circula a una velocidad superior a 40 km/h.Only if you are driving faster than 40 km/h.
    Explanation

    Explanation

    When a vehicle is parked on a poorly lit travesía, the parking lights must always be switched on or, if the vehicle does not have them, the position lights. Hazard warning lights are only used in an emergency. A travesía is the stretch of road that runs through a built-up area, so it is important for vehicles to be easy to see if the road is not well lit.

    Explanation

    Position lights and dipped headlights are compulsory between sunset and sunrise, whatever the visibility. Even if you can see the road clearly because it is getting light, you must switch on your lights to be seen by other road users. Driving with only the position lights is prohibited, because they show the presence and width of the vehicle but are not suitable for lighting the road while moving.

18. Nº 18

    • BPosición, y alumbrado de corto alcance o cruce.Sidelights and dipped headlights.
    • CPosición, y alumbrado de corto o largo alcance según se juzgue oportuno.Sidelights and dipped headlights or main beam, as you see fit.
    Explanation

    Under Article 101 of the General Traffic Regulations (RGC), in sufficiently lit tunnels you must always have your sidelights and dipped headlights on, whether or not there are other vehicles. Main beam is only used in tunnels that are not sufficiently lit.

    Un turismo circula por una travesía insuficientemente iluminada, ¿qué alumbrado debe llevar?

    A car is driving on a poorly lit travesía (stretch of road through a town). Which lights must it have on?

    • ASólo el alumbrado de posición.Only the position lights.
    • BEl alumbrado de posición y el de cruce.The position lights and dipped headlights.
    • CSólo el alumbrado de carretera.Only main beam.
    Explanation

    Dipped headlights must be used together with the position lights between sunset and sunrise on roads in built-up areas, travesías and well-lit roads outside built-up areas, and on poorly lit roads in built-up areas and travesías. Main beam is prohibited in built-up areas.

42. Nº 42

    En una vía urbana insuficientemente iluminada, ¿qué luces debe utilizar?

    On a poorly lit road in a built-up area, which lights must you use?

    • ASolo posición.Only position lights.
    • BPosición y luces de corto alcance.Position lights and dipped headlights.
    • CSolo luces largas.Only main beam.
    Explanation

    On a poorly lit road in a built-up area, the driver must use the position lights together with dipped headlights. This makes the vehicle visible to other road users and at the same time lights the carriageway properly without dazzling other drivers. Switching on only the position lights is not enough, because they do not light the road, and using only main beam is not appropriate either, because it could dazzle other vehicles on the road.

    Al circular, durante el día, por el carril contiguo a uno habilitado en sentido contrario al habitual, ¿debe llevar encendida alguna luz?

    When driving during the day in the lane next to one that has been opened to traffic in the opposite direction to normal, must you have any lights on?

    • ASí, la de corto alcance, al menos.Yes, at least dipped headlights.
    • BSí, la de posición.Yes, the position lights.
    • CNo.No.
    Explanation

    During the day, dipped headlights must be on for motorcycles on any road, inside or outside built-up areas, and for all vehicles driving in: - a reversible lane; - a temporary additional lane, and also vehicles driving on the hard shoulder; - a lane opened for traffic in the opposite direction to normal, whether the lane is reserved only for them or opened to traffic in that direction as an exception; - a lane with the normal direction of traffic next to a lane opened for traffic in the opposite direction to normal.

    Si Ud. es deslumbrado por las luces de largo alcance de otro vehículo, ¿qué debe hacer para evitar al alcance de vehículos o peatones que circulen en el mismo sentido?

    If you are dazzled by another vehicle's main beam, what should you do to avoid running into vehicles or pedestrians travelling in the same direction?

    • AApartarse lo más posible a la derecha de la vía, saliéndose de la calzada.Move as far as possible to the right of the road, leaving the carriageway.
    • BReducir la velocidad lo necesario, incluso hasta la detención total.Reduce speed as much as necessary, even coming to a complete stop.
    • CHacer señales con el alumbrado de carretera al vehículo que está deslumbrando.Flash your main beam at the vehicle that is dazzling you.
    Explanation

    Reducing speed as much as necessary, even coming to a complete stop, is correct because it gives you time to adapt to the situation and avoid an accident. By slowing down, you can control your vehicle better and pay more attention to what is happening around you, which is essential when you are dazzled by another car's lights.

    Si por la lluvia intensa en una vía interurbana no se distingue un vehículo negro a 50 metros, ¿se puede circular con las luces largas encendidas?

    If, because of heavy rain on a road outside a built-up area, you cannot make out a black vehicle at 50 metres, can you drive with main beam on?

    Explanation

    In poor visibility, such as heavy rain, the General Traffic Regulations require lights to be used. According to Article 106, when visibility is greatly reduced, the appropriate lights must be used. Main beam can be used to improve visibility on poorly lit roads outside built-up areas, when you cannot make out a black vehicle at 50 metres.

    Explanation
