     • Bpermite percibir posibles peligros con tiempo suficiente para reaccionar.let you notice possible hazards in time to react.
     • Cno resulta muy útil.are not very useful.
     Explanation

     In poor light, suitable lights let you see and be seen in time, so you notice hazards with enough time to react. That is why Article 106 of the General Traffic Regulations requires you to switch on your lights when fog, rain or other conditions considerably reduce visibility.

753. Nº 753

     ¿Los remolques deben llevar luces de frenado?

     Must trailers have brake lights?

     • ANo.No.
     • BNo están obligados, pero pueden llevarlas de forma opcional.They do not have to, but they may have them optionally.

     • ASí.Yes.
     • BNoNo.
     • CÚnicamente los ciclomotores podrán hacerloOnly mopeds may do so.
     Explanation

     Article 15.3 of the General Vehicle Regulations (Reglamento General de Vehículos) states that the rear fog light may only be switched on when the main beam, dipped headlights or front fog lights are also on. So having dipped headlights and the rear fog light on at the same time is normal and correct.

755. Nº 755

     

     ¿Están obligadas a llevar la luz de largo alcance las motocicletas con una cilindrada que no supere los 125 centímetros cúbicos?

     Must motorcycles with an engine capacity of no more than 125 cubic centimetres have a main-beam light?

     • BSí, una o dos luces.Yes, one or two lights.
     • CSí, si tienen sidecar; en el caso contrario no.Yes, if they have a sidecar; otherwise not.
     Explanation

     Article 16 of the General Vehicle Regulations requires every motorcycle, including those of up to 125 cm³, to have a main-beam (long-range) light. The technical regulations allow one or two to be fitted, whether or not the motorcycle has a sidecar.

     • BSí, pero sólo en la parte trasera.Yes, but only at the rear.
     • CNo, las motocicletas no pueden llevar luces antiniebla.No, motorcycles may not have fog lights.
     Explanation

     According to the General Vehicle Regulations, any motorcycle may have fog lights both at the front and at the rear. This is specifically mentioned in the article saying that motorcycles may choose to fit front and rear fog lights, which lets riders improve their visibility and safety in fog or poor visibility. So the correct answer is yes, they may have fog lights optionally.

757. Nº 757

     Si inmoviliza su vehículo durante el día en el arcén, ¿debe señalizarlo?

     If your vehicle is immobilised on the hard shoulder during the day, must you signal it?

     • ANo, ya que solo es obligatorio señalizar cuando el vehículo se encuentra en la calzada o es de noche.No, because you only have to signal when the vehicle is on the carriageway or it is night.
     • BNo, porque el arcén es el lugar adecuado para la inmovilización.No, because the hard shoulder is the right place to stop.
     • CSí, utilizando las luces de emergencia y el dispositivo de preseñalización.Yes, using the hazard warning lights and the hazard warning device.
     Explanation

     The correct answer is to signal it with the hazard warning lights and the hazard warning device, because when a vehicle is immobilised on the road or on the hard shoulder, other road users must be warned to avoid possible accidents. To do this, switch on the hazard warning lights and place the V-16 hazard warning device. This must be done both by day and by night, because other drivers need to notice the stopped vehicle in good time. Although the hard shoulder is a safer place, you must still signal that you are immobilised.

Driving on a two-way road does not require it.

763. Nº 763

     Es recomendable usar las luces de cruce durante el día.

     It is advisable to use dipped headlights during the day.

     • ANo, porque se consume mucha batería.No, because it uses a lot of battery.

764. Nº 764

     

     En una travesía, ¿está permitido circular con la luz de largo alcance encendida?

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

     • ANo.No.
     • BSí, en travesías insuficientemente iluminadas.Yes, on insufficiently lit travesías.
     • CSólo si se circula a una velocidad superior a los 40 km/h.Only if driving at more than 40 km/h.
     Explanation

     Main beam is prohibited in built-up areas, and for these purposes a travesía counts as a built-up area: main beam dazzles other road users, so dipped headlights must be used whether or not the road is lit.

765. Nº 765

     Circulando por una travesía insuficientemente iluminada, ¿qué alumbrado debemos utilizar?

     When driving through an insufficiently lit travesía (stretch of road through a town), which lights must we use?

     • ASolo la delantera.Only the front one.
     • BSolo la trasera.Only the rear one.
     • CSí, tanto la delantera como la trasera.Yes, both front and rear.
     Explanation

     Under the General Vehicle Regulations (Reglamento General de Vehículos, Article 16 and Annex X), motor vehicles must have a white light that lights up the rear number plate and comes on with the sidelights. The front plate has no lighting of its own.

771. Nº 771

     Cuando los dispositivos de alumbrado del vehículo se encuentran bien reglados, ¿pueden producir deslumbramiento a los demás usuarios?

     When the vehicle's lights are properly adjusted, can they dazzle other road users?

     • ANo.No.
     • BSí, el alumbrado de corto alcance o de cruce.Yes, the dipped headlights.
     • CSí, el alumbrado de largo alcance.Yes, the main beam.
     Explanation

     Even when properly adjusted, the main beam lights a long way ahead and dazzles oncoming drivers or those ahead. That is why you must switch to the dipped headlights, which are designed to light the road without dazzling.

772. Nº 772

     ¿Puede encender la luz de largo alcance cuando hay niebla de noche?

     May you switch on main beam in fog at night?

     • ASí, en sustitución de la luz antiniebla.Yes, instead of the fog light.
     • BNo, está prohibido.No, it is prohibited.
     • CSí, aunque no es recomendable porque puede deslumbrar.Yes, although it is not advisable because it can dazzle.
     Explanation

     Drivers generally think that main beam lights up the road very well and dipped headlights only a short distance. If we switch on main beam in fog, it will only light up the fog and our vision will not improve; it may even dazzle us. That is why it is advisable to switch on dipped headlights or the appropriate fog light.

773. Nº 773

     

     Si es necesario avisar a un ciclista con señales acústicas, ¿cómo debe hacerse?

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

     • AEstá prohibido hacer señales acústicas.Using the horn is prohibited.
     • BA cierta distancia del ciclista, para evitar que se asuste.From some distance away, so the cyclist is not startled.
     • CLo más cerca posible del ciclista, para asegurarnos de que nos oye.As close as possible to the cyclist, to make sure they hear us.
     Explanation

     The correct use of the horn towards a cyclist is in Article 110 of the General Traffic Regulations. This article says the horn must only be used as an exception and always in situations where it is needed to avoid an accident. It is also important to warn from a suitable distance so as not to startle the cyclist, in line with the principle of looking after the safety and calm of all road users. So the correct answer is to warn from some distance away from the cyclist.

774. Nº 774

     ¿En caso de que un tractor agrícola lleve luces de largo alcance cuántas deben ser?

     If an agricultural tractor has main beam headlights, how many must there be?

     • CVías interurbanas suficiente o insuficientemente iluminadas.roads outside built-up areas, whether sufficiently or insufficiently lit.
     Explanation

     Main beam, also called high beam, is designed for use on roads outside built-up areas that are not sufficiently lit. This is because on these roads there is less traffic and visibility may be limited, so it is important to see and be seen. Using main beam in these conditions improves safety by giving a better view of the road and of other vehicles.

776. Nº 776

     ¿Qué alumbrado llevaremos en un túnel?

     Which lights will we have on in a tunnel?

     • AEl de posición.Sidelights.

     • CLa luz antiniebla trasera y la luz de corto o largo alcance.The rear fog light and dipped headlights or main beam.
     Explanation

     Vehicles driving in weather or environmental conditions that greatly reduce visibility must have the appropriate lights on. These may be dipped headlights or the front fog light, which may be used optionally in fog, heavy rain, snow, clouds of smoke or dust, or similar conditions. In especially bad weather or environmental conditions, the rear fog light must be used together with the sidelights and also with dipped headlights, main beam or the front fog light.

779. Nº 779

     • BLos indicadores de direcciónThe indicators
     • CLuces de frenadoThe brake lights
     Explanation

     A vehicle's indicators are never fixed and steady, because the light they give out always flashes, that is, it switches between on and off. The brake lights and the rear fog light, on the other hand, are fixed and steady.

780. Nº 780

     La luz de estacionamiento debe utilizarse...

     Parking lights must be used...

     • Aal estacionar en travesías insuficientemente iluminadas.when parking on insufficiently lit travesías (roads through towns).
     • Ben las paradas en doble fila.when stopping in double file.
     • Cen las detenciones en vías urbanas suficiente o insuficientemente iluminadas.when held up on urban roads, whether sufficiently or insufficiently lit.
     Explanation

     Parking lights may be used between sunset and sunrise, or in weather or environmental conditions that greatly reduce visibility, to signal vehicles parked on the carriageway or hard shoulder of an insufficiently lit travesía. If our vehicle has no parking lights, we may leave on the sidelights on the side facing the carriageway, if the vehicle is parked parallel to the kerb.

781. Nº 781

     • CLas de largo alcance o carretera, siempre que no deslumbre a otros usuarios.Main beam, as long as it does not dazzle other road users.
     Explanation

     In an insufficiently lit tunnel, when driving at more than 40 km/h, you must have main beam on, except when it has to be replaced by dipped headlights so as not to dazzle other road users (Article 100.1 of the General Traffic Regulations).

782. Nº 782

     

     En un carril habilitado en un sentido contrario al habitual, ¿qué luces se deberán utilizar?

     • CLas de cruce o corto alcance, tanto de día como de noche.Dipped headlights, both by day and by night.
     Explanation

     In these lanes dipped headlights must be used both by day and by night. It goes without saying that when using these lights we are also using the sidelights, because switching on dipped headlights automatically switches on the sidelights.

783. Nº 783

     • CLa misma distancia.The same distance.
     Explanation

     If the dipped headlights are adjusted lower than they should be, their beam hits the road closer to the vehicle and lights a shorter distance, so the driver sees obstacles later. If they are too high, on the other hand, they dazzle others.

800. Nº 800

     En carretera, usted circula con las luces de cruce debido a una avería. ¿Qué debe hacer?

     On the road, you are driving with dipped headlights because of a fault. What must you do?

     • AConducir a una velocidad que le permita detener el vehículo dentro de la zona iluminada si fuera necesario.Drive at a speed that lets you stop the vehicle within the lit area if necessary.
     • BCircular por el arcén solo si es necesario y de forma segura.Drive on the hard shoulder only if necessary and safe.
     • CDetener el vehículo en el arcén si la avería impide continuar.Stop the vehicle on the hard shoulder if the fault stops you from continuing.
     Explanation

     When driving with dipped headlights because of a fault, the rules say you must drive at a speed that lets you stop the vehicle within the lit area if necessary. This is because dipped headlights have a limited range, and the driver must be able to react properly to any obstacle or unexpected situation. The General Traffic Regulations say that poor visibility or incorrect use of lights can lead to serious offences, which makes this precaution vital.
