Safety advice in case of fog

In the event of fog, visibility is reduced. Often you can no longer orient yourself using the usual landmarks (trees, beacons, etc.). At the same time, you lose your sense of speed: you risk driving faster than you think, seeing an obstacle too late (slow vehicle, broken down vehicle...) or not being seen in time by another road user.

It is therefore important to adapt your speed according to the visibility.

Use of fog lights

When visibility to the front is less than 100 metres due to fog, the fog lights should be switched on.

The same applies to the rear fog lights, which should be switched on as soon as visibility is less than 50 metres in order to draw attention to a car.

Automatic activation of lights

Many road users use automatic lights. However, this can cause safety problems depending on the weather conditions.

For example, the lights have to be activated manually in foggy conditions. The majority of automatic lighting systems do not yet offer automatic activation in this case.

Even at dawn, in rain or snow (daytime), the lighting is not necessarily activated by the automated system, which therefore constitutes a safety risk.
