    ¿Cuantas luces de estacionamiento debe tener un vehículo?

    How many parking lights must a vehicle have?

    • AÚnicamente dos luces traserasOnly two rear lights.
    • BTres delanteras y tres traserasThree at the front and three at the rear.
    • CDos delanteras y dos traserasTwo at the front and two at the rear.
    Explanation

    The parking lights consist of two white lights at the front and two red lights at the rear, in the same place as the position lights. Parking lights may only be used instead of the position lights on poorly lit travesías (stretches of road through a town) when the vehicle is parked parallel to the kerb.

  3. Nº 103

    El alumbrado, los neumáticos y los frenos forman parte del sistema de...

    The lights, tyres and brakes are part of the system of...

    • Aconducción eficiente.eco-driving.
    • Bseguridad pasiva.passive safety.
    • Cseguridad activa.active safety.
    Explanation

    In the General Traffic Regulations and the Traffic and Road Safety Code, the elements that allow the driver to control the vehicle and prevent accidents while driving are classed as 'active safety'. The lights, tyres and brakes are essential devices that ensure visibility, grip and stopping of the vehicle; so they are part of active safety. Passive safety, on the other hand, includes devices that protect the occupants once a collision happens (seat belts, energy-absorbing structures, airbags). Eco-driving refers to systems aimed at reducing fuel consumption and emissions, but it does not directly affect control of the vehicle.

  4. Nº 104

    ¿Es obligatorio usar la luz antiniebla trasera cuando la lluvia es muy intensa?

    Is it compulsory to use the rear fog light when the rain is very heavy?

    • ASí.Yes.
    • BNo, es opcional.No, it is optional.
    • CNo, sólo debo usarla en caso de niebla muy densa.No, I should only use it in very dense fog.
    Explanation

    Under Article 106.2 of the RGC, the rear fog light must be switched on in especially unfavourable conditions, such as thick fog, very heavy rain, heavy snowfall or dense clouds of dust or smoke. It is not used in moderate rain or drizzle, because it dazzles those driving behind.

    • CNo deslumbrante y no visibleNot dazzling and not visible.
    Explanation

    The reversing light consists of one or two lights, not dazzling and visible both by day and at night, which must be placed at the rear of the vehicle. Its purpose is to warn other road users that the vehicle is reversing.

  6. Nº 106

    ¿Cuándo se considera que una vía está mal iluminada?

    When is a road considered poorly lit?

    • ACuando no se puede leer la matrícula a 10 metros.When you cannot read a number plate at 10 metres.

    • CCuando no se puede leer la matrícula a 50 metros.When you cannot read a number plate at 50 metres.
    Explanation

    A road is considered poorly lit when you cannot read a number plate at 10 metres. This rule is set out in the General Traffic Regulations, in the article that defines adequate road lighting. Not being able to read at this distance shows that visibility is poor, which can put road safety at risk.

    Explanation

    FRONT FOG LIGHT: - Fitting and using it is NOT compulsory. - It is white or selective yellow. - It may be used, if you choose, in fog, heavy rain, snowfall, clouds of smoke or dust, or in similar conditions. - It may also be used on narrow roads with many bends, that is, roads with a carriageway 6.5 m wide or less that are marked with 'dangerous bends' signs. REAR FOG LIGHT: - Fitting and using it is compulsory. - It is red. - It must be used in THICK fog, VERY heavy rain, HEAVY snowfall or DENSE clouds of smoke or dust (it is prohibited to use it in other situations). During the day, the front fog light may be on with just the position lights, but it can also be used together with dipped headlights or main beam. At night, it must be used at least with dipped headlights. During the day, the rear fog light must be used at least together with the front fog light or dipped headlights. At night, at least with dipped headlights.

    • Aluz de cruce (cortas), como mínimo.dipped headlights, at least.
    • Bluz de carretera (largas).main beam headlights.
    • Csolo las luces de posición, si el túnel está bien iluminado.only the sidelights, if the tunnel is well lit.
    Explanation

    The 'Tunnel' sign (S-5) means lights must be on at any time of day (Article 98.1 of the General Traffic Regulations). Even if the tunnel is well lit, you must use dipped headlights as well as sidelights (Article 101.1); main beam only if the tunnel is poorly lit, you are driving at more than 40 km/h and you will not dazzle anyone.

  14. Nº 114

    Al conducir con visibilidad muy reducida, ¿es obligatorio encender la luz antiniebla trasera?

    When driving with very reduced visibility, is it compulsory to switch on the rear fog light?

    • CSí, para señalar su posición a otros usuarios de la vía.Yes, to show your position to other road users.
    Explanation

    When conditions are especially unfavourable and visibility is very reduced (thick fog, very heavy rain, heavy snowfall), the rear fog light must be on, on any type of road (Article 106.2 of the General Traffic Regulations), so that those behind can see the vehicle.

  15. Nº 115

    Si dos vehículos se cruzan en una curva con las luces largas encendidas, ¿cuál de los dos pasará antes a las luces de cruce?

    If two vehicles with main beam on meet on a bend, which of them will switch to dipped headlights first?

    • AEl que circula por la parte exterior de la curva.The one on the outside of the bend.

    Explanation

    Article 102 of the General Traffic Regulations requires you to switch to dipped headlights as soon as you could dazzle someone else. On a bend, the headlights of the vehicle on the inside point towards the opposite lane and dazzle sooner, so it is that vehicle that must switch first.

  16. Nº 116

    Question picture

    Si es necesario avisar a un ciclista con señales acústicas, ¿cómo deben realizarse?

    If you need to warn a cyclist with the horn, how should you do it?

    Explanation

    This is the compulsory dipped headlights sign (R-413), common at tunnel entrances. From this sign you must have at least your dipped headlights on, by day or by night, until the end sign; sidelights alone do not meet this requirement.

  21. Nº 121

    Circulando de noche por una vía interurbana suficientemente iluminada, además de las luces de posición, ¿debemos encender alguna otra luz?

  26. Nº 126

    Si circulamos de día con niebla espesa, ¿qué luces debemos llevar encendidas como mínimo?

    If we are driving during the day in thick fog, which lights must we have on as a minimum?

    • BLuz antiniebla trasera y luces de cruce.Rear fog light and dipped headlights.
    • CLuz antiniebla trasera y delantera, más luces de cruce.Rear and front fog lights, plus dipped headlights.
    Explanation

    In thick fog the rear fog light is compulsory, and at the front you must use the front fog light or the dipped headlights or main beam (Article 106.2 of the General Traffic Regulations). So the minimum required is the rear fog light plus dipped headlights; the front fog light is optional.

  27. Nº 127

  32. Nº 132

    Question picture

    Por una avería y de día, ¿qué debe hacer si su vehículo queda inmovilizado en una autopista?

    During the day, what must you do if your vehicle breaks down and comes to a standstill on a motorway (autopista)?

    Explanation

    Since 2026 the hazard warning device is the V-16 light, which is placed on the highest part of the vehicle without having to step onto the carriageway. Article 130 of the General Traffic Regulations requires you to use it and to switch on the hazard warning lights if the vehicle comes to a standstill because of a breakdown.

  33. Nº 133

    Es de día, hay niebla y el vehículo no tiene luces antiniebla delanteras. ¿Qué luces debe encender?

    Explanation

    In fog you must switch on your lights even during the day: the front fog lights or, if there are none, dipped headlights or main beam (Article 106 of the General Traffic Regulations (RGC)). Dipped headlights are the right choice because they reflect less in the fog; sidelights alone are not enough.

  34. Nº 134

    • AIluminar la calzada a gran distancia.Light up the carriageway at a great distance.
    • BHacer visible el vehículo a los demás, sin alumbrar apenas la vía.Make the vehicle visible to others, while hardly lighting up the road.
    • CSustituir a la luz de cruce en carretera.Replace the dipped headlights on the open road.
    Explanation

    According to the definitions in Annex X of the General Vehicle Regulations (RGV), sidelights show the presence and width of the vehicle when seen from the front or rear, but they hardly light up the road. To see the carriageway you need dipped headlights or main beam.

  37. Nº 137

    Question picture

    Usted debe utilizar las luces de carretera si circula a más de 40 kilómetros por hora ...

    You must use the main beam if you are driving at more than 40 kilometres per hour…
