Question 6172
If there is no thick fog, in what other circumstance may you use the front fog light?
- In any circumstance in which visibility is reduced.
- On narrow stretches of road with a succession of dangerous curves that are signposted, at night.
- You may only turn on the front fog light in thick fog.
Show answer and explanation
Correct answer: On narrow stretches of road with a succession of dangerous curves that are signposted, at night.
Front fog lights do not require thick fog. In bad weather, fog, heavy rain, snow, smoke or dust that greatly reduces visibility is enough. Nighttime alone is not enough. Without bad weather, they are allowed on sections with signs warning of a series of dangerous curves if the roadway is 6.50 meters wide or less. In the image, the oncoming car next to the curve warning sign has its front fog lights on.
