Question 7525
When there is fog, must you have the rear fog light on?

- No, except if you are driving faster than 80 km/h.
- Only if the fog is thick.
Show answer and explanation
Correct answer: Only if the fog is thick.
In fog, you must turn on the rear fog light only when the fog is thick. In light fog, it is prohibited because it blinds the driver behind you, and your speed makes no difference. In the image, the fog is thick and the car ahead has its rear fog light on.
