Correct answer

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

As vehicles do not have to be fitted with front fog lights, using them is not compulsory either. The rear fog lights are only used in thick fog. So using the position lights and dipped headlights will be enough in this case.
