Question 5264

Between sunset and sunrise, may you switch on your high-beam headlights in fog?

Show answer and explanation

Correct answer: Yes, taking care not to blind other road users.

Fog does not prohibit the use of high beams. Outside built-up areas, you may use them when appropriate, provided you do not blind anyone, including together with low beams or front fog lights. Still, they are not recommended in fog because the droplets reflect the light back at you and make it harder to see. In the image, there is a car ahead of you, and your high beams could blind its driver through the rearview mirror.
