BDifficulty 3/5

You drive in heavy rain, but not very heavy rain, with no other especially adverse conditions. Must you switch on the rear fog light for that rain?

Correct answer

No, that rain alone does not meet the conditions for using the rear fog light.

No. Rear fog lights are used only in especially adverse conditions, such as very heavy rain, thick fog or heavy snowfall. Heavy rain substantially reducing visibility requires the lighting specified in Article 106, but does not alone require the rear fog light. Front fog lights may be used in authorised conditions; they are not mandatory in every rainfall. Switch the rear light off when the condition justifying it ends.
