Question 3834

When driving in very heavy rain, can the front and rear fog lights be used?

  1. Yes, and the rear fog light must also be used.
  2. Yes, but only the front fog light.
  3. No, because they can only be used in fog.
Show answer and explanation

Correct answer: Yes, and the rear fog light must also be used.

In very heavy rain, you may turn on the front fog lights, and the rear fog light becomes mandatory because this is one of the especially unfavorable conditions. Fog lights are not just for fog. In rain that is heavy, but not very heavy, you may use the front fog lights, but the rear fog light must stay off.
