Correct answer

  • BSí, cuando el vehículo no dispone de luces antiniebla delanteras.Yes, when the vehicle has no front fog lights.
Explanation

Article 106 of the General Traffic Regulations allows you, in fog, to use the front fog light or dipped headlights or main beam. So if the vehicle has no front fog light, sidelights and dipped headlights are enough. The rear one is only for dense fog.
