Question 7522

In which of the following situations must you drive with the rear fog light on?

  1. In especially unfavorable weather conditions such as heavy snowfall.
  2. On a 6-meter-wide roadway marked as a stretch of dangerous curves close together.
  3. Whenever it is mandatory to drive with the front fog light on.
Show answer and explanation

Correct answer: In especially unfavorable weather conditions such as heavy snowfall.

The rear fog light is required in heavy snowfall and other especially unfavorable conditions. A narrow section with curves only allows the use of front fog lights, and having front fog lights on does not require you to use the rear fog light. In the image, it is snowing heavily and the car ahead has its rear fog light on.
