BDifficulty 2/5

A car has front and rear fog lights on at night on a straight section, with no fog or other reduced visibility. Is it correct to keep them on in that situation?

Correct answer

No, the fog lights must be switched off.

No: switch off both fog lights and retain the lighting otherwise required. Article 106 permits front fog lights with substantially reduced visibility, or on narrow sections with many bends, the required signs and a carriageway 6.50 metres wide or less. Width alone is insufficient. Rear fog lights are used only in especially adverse conditions. Night-time on a straight section does not permit their use without those conditions.
