BDifficulty 2/5

During the day, when dust or smoke clouds significantly reduce visibility, which lighting must you use?

Correct answer

The front fog light, or the dipped-beam headlights, or the main-beam headlights.

In addition to position lights, use front fog lights or dipped or main beam as appropriate. Front fog lights are not always the mandatory choice: dipped beam is an option provided by the rule. Main beam must not dazzle. Rear fog lights are reserved for especially adverse conditions, such as dense dust or smoke clouds.
