The AA has put together this handy list of 10 top tips for driving safely in fog:

1.Use dipped headlights at all times along with wipers and demisters.

2.Familiarise yourself with your front and rear fog lights – know how to switch them on and off – and use them when appropriate.

3.Beware of other drivers not using headlights.

4.Only drive as fast as conditions allow and maintain a greater distance between you and the car in front. Follow a three-second rule.

5.Tailing someone's rear lights can give a false sense of security and is dangerous.

6.If the road has street lights on, then you probably don't need your fog lights on.

7.Be able to stop within the distance you can see clearly – this is particularly important on motorways and dual carriageways, as vehicles are travelling faster.

8.Don't accelerate to get away from a vehicle that is too close behind you.

9.Check your mirrors before you slow down.

10.At a junction with limited visibility, stop, wind down the window, andlisten for traffic. When you are sure it is safe to emerge, do so positively and do not hesitate in a position that puts you directly in the path of approaching vehicles.
