How to drive safely in fog

• If you have front fog lights use them. Don't be tempted to use your full beam headlights as most of the light will just be reflected back at you, reducing your visibility


• Rear fog lights are designed to be used only in thick fog, if visibility is more than 80 metres they may just succeed in dazzling drivers behind you and obscuring the operation of your brake lights


• Do not be tempted to 'hang-on' to another drivers tail lights, this may lull you into a false sense of security


• SLOW DOWN and keep plenty of distance between you and the car in front. Even if other drivers seem to think they have x-ray vision, it will be you that avoids going into the back of another vehicle if it stops because visibility has reduced suddenly


• Take extra care when pulling out at junctions. Your instincts tell you that the dim glow of headlights means that a vehicle must be some way off. Judging both the speed and distance of another vehicle in fog is very misleading, they may be much closer and moving much faster than you think


• Use your wipers often, the moisture on your windscreen can sometimes be mistaken for the fog outside
