After fog engulfed Lincoln last night, our readers have asked us to clear up how to properly use your fog lights.
So, here is some advice on driving safely in foggy conditions.
- You must use headlights when visibility is seriously reduced, generally when you cannot see for more than 100 metres (328 feet). You may also use front or rear fog lights but you must switch them off when visibility improves.
- Before entering fog check your mirrors then slow down. If the word ‘Fog’ is shown on a roadside signal but the road is clear, be prepared for a bank of fog or drifting patchy fog ahead. Even if it seems to be clearing, you can suddenly find yourself in thick fog.
- When driving in fog you should use your lights as required and keep a safe distance behind the vehicle in front. Rear lights can give a false sense of security so be able to pull up well within the distance you can see clearly. This is particularly important on motorways and dual carriageways, as vehicles are travelling faster.
- You must not use front or rear fog lights unless visibility is seriously reduced as they dazzle other road users and can obscure your brake lights. You must switch them off when visibility improves.
