How to use your fog lights and drive in foggy conditions

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.

    Just as bad as those drivers who don't switch off their rear fog lights when cars draw near to them are those idiots who sit on their brakes at junctions. These dazzle you as much as fog lights. Have they never heard of handbrakes?

    Roadscource wrote "The times I have seen cars in foggy conditions THEN seen their sidelights" Not that foggy then? If it was not so foggy I would have seen the sidelights before the car. It is BECAUSE of the density of the fog that you see the outline of the car before the sidelights Sidelights are only 5 watts. Headlights are 55/60 watts. The lights on the big Volvos are 21 watts (same strength as winkers) The LED lights on the front of alot of new cars are much brighter.

    Remember side lights are parking lights ONLY. The times I have seen cars in foggy conditions THEN seen their sidelights

    I would pose the question that if you do not know how to use your lights then should you actually be on the road behind the wheel at all? It always amazes me, also, why so many brand new cars would fail an MOT test because of faulty or non working indicator lights!

    Tell that to these people who insist on using their front fog lights as driving lights

    Please can you send this to the numpy who was driving about 3ft behind me on the A158 towards Horncastle last night. Visibility was so bad at times you couldn't see 30ft ahead but he clearly thought the closer he drove the easier it would be for him. Idiot. Thanks.
