Driving In Fog

Driving in fog means adjusting speed, lights and distance because visibility is greatly reduced.

What is Driving In Fog?

Use dipped headlights, not main beam, which reflects back. Front and rear fog lights help when visibility is very poor. Many countries set a visibility limit for using rear fog lights. In some countries the speed limit drops automatically when visibility falls below a set distance.

How it works

Water droplets scatter light and hide vehicles and obstacles until they are close.

Why it matters for your car

Switch off rear fog lights when visibility improves so they do not dazzle. Slow down so you can stop within the distance you can see.
