BDifficulty 3/5

You come across a vertical sign warning of the approach of a stretch of road with numerous dangerous bends. Is it permitted to use the rear fog light in this area at night?

Correct answer

No, except in adverse weather conditions.

The rear fog light may only be used when the weather or environmental conditions on the road are particularly unfavourable, such as thick fog, very heavy rain, heavy snowfall or dense clouds of dust or smoke. Its use is not permitted in any other circumstance, even in areas with numerous bends and at night.
