What is the purpose of the rear anti-fog lights of a passenger car?
Description
Annex 1 pt 4.12.1. p. 11983 of the Regulation of the Minister of Infrastructure of 18 September 2009 on the scope and method of conducting tests (Journal of Laws No. 155, item 1232)
Explanation
Correct answer: They improve the visibility of the car in fog.
Rear fog lights are used to make the vehicle more visible to drivers behind in conditions of significantly reduced air transparency. According to Art. 30 para. 1 of the Road Traffic Act, they may only be used when visibility drops below 50 metres. They must be switched off immediately when visibility improves, as their intense red light can dazzle other road users.
