BDifficulty 2/5

At night outside built-up areas on a poorly lit road, main beam fails and cannot be repaired en route, but dipped beam works. If continuing is safe, what must you do?

Correct answer

Use dipped beam and reduce speed to allow stopping within the illuminated area.

Use dipped beam and reduce speed enough to stop within the illuminated area, under Article 107, while meeting other applicable conditions. Continuing at any speed is not guaranteed: if unsafe, stop somewhere safe and request assistance. Fog lights do not automatically replace failed lighting, and stopping on the carriageway with parking lights is not the general solution.
