Correct answer

  • 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.
