BDifficulty 2/5

In thick fog, a car without front fog lamps is using dipped headlights. Which additional combination must remain switched on?

Correct answer

Position lights and rear fog lamp, maintaining dipped headlights.

Position lights and the rear fog lamp, together with the dipped headlights already in use. Article 106 reserves rear fog lighting for particularly adverse conditions, such as thick fog. It does not require front fog lamps or dipped beam as the sole alternative for every vehicle: other legal combinations are allowed. Here the car has no front fog lamps and is using dipped headlights. Switch off the rear fog lamp when the qualifying conditions end and adapt speed and following distance to visibility.
