When must you turn off the rear anti-fog light?

Description

Art. 30 para. 3 and Art. 51 para. 3 of the Road Traffic Act (Journal of Laws of 2012, item 1137)

Explanation

Correct answer: When visibility increases to 60 m.

The indicator light shown signals that the rear fog lights are on. According to Art. 51 para. 3 of the Road Traffic Act, they must be switched off immediately when visibility improves to more than 50 metres. Leaving them on unnecessarily is not permitted, as their strong, red light dazzles drivers behind.
