BDifficulty 2/5

At night outside a built-up area, a car travels above 40 km/h on an insufficiently lit road using main beam without dazzling anyone. While being overtaken, what must it do when its lights could dazzle the other driver through the mirror?

Correct answer

Switch to dipped beam as soon as dazzling is possible.

Switch to dipped beam as soon as dazzling becomes possible, under article 102. Do not wait for the overtaking vehicle to return to the lane ahead if it could be dazzled earlier. Article 100’s main-beam duty depends on its conditions and yields to the duty to avoid dazzling. Brake lights do not replace the lighting needed to see the road.
