    • BAlumbrado de posición con el de largo alcance.Position lights with main beam.
    • CSolamente alumbrado de posición.Only position lights.
    Explanation

    When we drive on a road outside a built-up area where it passes through a town (a travesía is inside a built-up area), we use the position lights together with dipped headlights, whether it is well lit or poorly lit.

  3. Nº 53

    Circulando con nuestra motocicleta un día de lluvia intensa, ¿qué alumbrado utilizaremos?

    The position light and the dipped headlight are necessary in heavy rain to make the vehicle more visible and warn other road users that we are there. It is important to use at least these lights to reduce the risk of accidents.

  4. Nº 54

    La regulación, el funcionamiento y el estado del sistema de alumbrado, ¿hay que revisarlos con frecuencia?

    Should the adjustment, operation and condition of the lighting system be checked often?

    • BSí.Yes.
    • CNo, sólo es necesario cambiar las bombillas cuando estén fundidas.No, you only need to change the bulbs when they have blown.
    Explanation

    Lights are very important to see and be seen. Each light must shine in a particular way; for example, dipped headlights must light a sufficient distance without dazzling other road users. If they are not properly adjusted, they could dazzle others, or we might not see far enough. That is why we must check the lights often.

  5. Nº 55

    • CLas luces de cruce y, en caso de disponer de ellas, las luces antiniebla delanteras.Dipped headlights and, if fitted, the front fog lights.
    Explanation

    In reduced visibility, such as fog, heavy rain, snowfall or smoke or dust, it is compulsory to use the appropriate lights. In these cases you must use dipped headlights and, depending on the conditions, the front fog light, as long as the vehicle has one, as fitting it is not compulsory. This light can be used alone or together with dipped headlights or main beam, depending on the situation. The rear fog light, for its part, must only be used when conditions are especially unfavourable, such as thick fog, very heavy rain, heavy snowfall or dense clouds of dust or smoke, because using it wrongly can dazzle other road users.

  8. Nº 58

    En una zona poblada, ¿está permitido usar señales acústicas?

    In a built-up area, are you allowed to use your horn?

    • ASí, solo para evitar un accidente.Yes, only to avoid an accident.

    Explanation

    In built-up areas the horn may only be used to avoid a possible accident or to warn others that an emergency service is being carried out (Article 110.2 of the General Traffic Regulations, in connection with Article 70). Warning another driver that you are about to overtake is only allowed outside built-up areas.

  9. Nº 59

  10. Nº 60

    ¿Hay que revisar con frecuencia el ajuste, el funcionamiento y el estado del sistema de alumbrado?

    Should the adjustment, working order and condition of the lighting system be checked often?

    • BSí.Yes.
    • CNo, sólo hay que cambiar las bombillas cuando se funden.No, you only need to change the bulbs when they blow.
    Explanation

    It is advisable to check often that all the lights work, are clean and are properly adjusted: a blown bulb or a badly aimed headlight reduces visibility, may dazzle others and means other road users do not notice what we are doing. It is not enough to change bulbs when they blow.

    • AEs obligatorio utilizarlo.is compulsory.
    • BEstá prohibido utilizarlo.is prohibited.
    • CNo suele ser el más adecuado.is not usually the most suitable.
    Explanation

    In heavy rain you must switch on your lights, but main beam is not usually the most suitable: it reflects off the raindrops and dazzles the driver. It is usually better to use dipped headlights or the front fog light. It is neither prohibited nor compulsory.

  16. Nº 66

    ¿Está permitido usar las luces largas al circular por una travesía?

    Are you allowed to use main beam when driving through a travesía (stretch of road through a town)?

  18. Nº 68

    En caso de no disponer de luces antiniebla delanteras, ¿qué luces utilizaremos en caso de niebla no espesa?

    • BCorto alcance o posición.Dipped headlights or position lights.
    • CPosición.Position lights.
    Explanation

    In fog that is not thick, we use at least dipped headlights. If we have a front fog light, we may use it if we choose.

  19. Nº 69

    • CTanto la de ver como la de ser visto por los demás usuarios de la vía.Both to see and to be seen by other road users.
    Explanation

    Lights have a double purpose: they let the driver see the road and its obstacles, and they make the vehicle visible to other road users. That is why position lights or dipped headlights are also switched on in situations where you can see well, such as in tunnels or in rain.

  21. Nº 71

    Explanation

    During the day you must have the appropriate lights on in tunnels, underpasses and stretches covered by the “Tunnel” sign (Article 98.1 of the General Traffic Regulations). It is not enough to switch them on only when visibility is poor, and HOV (VAO) lanes do not require it on their own.

  28. Nº 78

    ¿Se debe revisar periódicamente el sistema de alumbrado del vehículo como parte del mantenimiento preventivo?

    Should the vehicle's lighting system be checked regularly as part of preventive maintenance?

    Explanation

    Regular checking of the vehicle's lighting system is an important part of preventive maintenance. It includes checking that the headlights, indicators, brake lights and fog lights work. Incorrectly adjusted headlights can dazzle other drivers or light the road poorly, especially at night. In Spain, drivers are advised to check the condition of their lights regularly and adjust them if necessary.
