ExplanationThe position lights must come on automatically when the vehicle has dipped headlights, main beam or fog lights on. When driving, they must always be used together with one of these. We must switch them on between sunset and sunrise, or in weather or environmental conditions that reduce visibility: * when stopped on the carriageway or hard shoulder of any road, including tunnels, underpasses or enclosed places; * also when parked: - on a hard shoulder that cannot be driven on, on a road outside a built-up area; - on the carriageway or hard shoulder of a poorly lit travesía; - on the carriageway or hard shoulder of a road in a built-up area, when the lighting does not let other road users see the vehicle from a sufficient distance.

Dipped headlights are also compulsory:
- AAl circular bajo lluvia intensa, niebla o nieveWhen driving in heavy rain, fog or snow.

ExplanationAt night, on a sufficiently lit urban road, you must have your sidelights and dipped headlights on (Articles 99.1 and 101.1 of the General Traffic Regulations). Main beam is intended for interurban roads that are not well enough lit, not for a well-lit street.

ExplanationUnder the General Traffic Regulations, it is prohibited to keep main beam on when the vehicle is stopped or parked. This is set out specifically in the rules on the use of vehicle lights, to avoid dazzle and ensure road safety. So the correct answer is that you may NOT keep main beam on when you stop.

- Bse circule por carreteras de alta montaña.you are driving on high mountain roads.

ExplanationA red light flashing forwards from a police vehicle behind you tells the driver to stop on the right-hand side, in front of the police vehicle, in a place without risk, and to follow the officer's instructions (Annex I of the General Traffic Regulations). Getting out of the vehicle without being told to is not correct.

Is a reversing light compulsory on three-wheeled motorcycles?
- ASí, siempre.Yes, always.
- BNo, nunca.No, never.
- CNo, pero se puede instalar.No, but one may be fitted.

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.

In addition, when driving on any type of road in conditions where visibility is much lower than normal, such as fog, heavy rain, snowfall, clouds of smoke or dust or any similar situation, dipped headlights must also be used.
