BDifficulty 2/5

A dust cloud significantly reduces visibility. Under Article 106, which lighting must be used in addition to position lights while obeying other applicable rules?

Correct answer

Front fog lamps, dipped or main beam subject to their use rules.

Front fog lamps, dipped beam or main beam under Article 106.1. Use conditions and the prohibition on dazzle must be respected; reflections may favour dipped beam or fog lamps. Rear fog lamps are only appropriate in especially adverse conditions such as a dense dust cloud, not any reduction of visibility.
