In Hungarian road traffic rules, when must rear fog lamps (hátsó helyzetjelző ködlámpa) be switched off?

Answer and explanation

Correct answer: D. When visibility improves or when another vehicle follows closely behind

  1. Step 1: Rear fog lamps produce an intense red glare; they must be switched off as soon as visibility improves or when a trailing vehicle closes up. Answer: When visibility improves or when another vehicle follows closely behind. Why not the others: Intense rear fog lights dazzle trailing drivers and obscure brake lights.
