BDifficulty 2/5

A passenger car enters an insufficiently lit tunnel by day, and main beam could dazzle other users. Which lights must be on?

Correct answer

Position lights and dipped beam.

Position lights and dipped beam. Under these conditions, position lights alone are insufficient and dazzling main beam must not be used. Tunnel lighting requirements also apply by day; they do not depend on it already being night. Front fog lighting does not replace the dipped beam required in this situation.
