No, the rear fog light didn’t need to be turned on this morning either!

Yes, it was foggy this morning, but you could definitely see a hand in front of your eyes. It is therefore surprising how many drivers drive with the rear fog light on.

All cars must have at least one rear fog light. This is a particularly bright red lamp that is intended to make you more visible in dense fog. Two rear fog lights are also permitted.

Rear fog light: one or two

Not all road safety experts are happy about this. Some believe that two rear fog lights can easily be confused with illuminated brake lights.

The rules are clear

Anyway, it was foggy this morning. So why isn’t the intention to turn on the rear fog lights? Because the rules are clear. It is only permitted if visibility is less than 50 meters.

And whether the visibility is less than 50 meters can be easily determined on the street. The reflector posts along the road are 50 meters apart. So if you can see the next one, the rear fog light doesn’t need to be on.

Turn off the rear fog light

If you turn on the rear fog light, don’t forget to turn it off again when the fog clears.

The opposite is also true. Modern cars have automatic lights that turn on when it gets dark. The sensor often does not detect fog, so you have to turn on the light yourself.
