DRIVING IN FOG
Tips for calm and safe driving in foggy conditions
According to the Rules of the Road, you must use your headlights when your visibility becomes reduced to 100m or less.
There's no obligation to use fog lights, but if you do, they must be switched off once visibility improves. If your car is involved in an accident in reduced visibility and your fog lights aren’t on, then it may be queried by an insurer according to the AA Car Insurance team.
You should be extra vigilant when driving in fog, as visibility can deteriorate in a matter of seconds.Use your common sense when it comes to fog lights and as obvious as it sounds, know how to turn them on! Generally speaking, it's better to be safe than sorry, so use them when appropriate. However, you shouldn’t keep switching them on and off as this can be a distraction. Wait for a consistent improvement in visibility before switching them off.
AA Advice on driving in Fog:
* Use your dipped headlights at all times plus your windscreen wipers and demisters.
*Familiarize yourself with your front and rear fog lights. Know how to switch them on and off and use them only when appropriate.
* Beware of other drivers not using headlights.
* Only drive as fast as conditions allow and maintain a greater distance between you and the car in front. Tailing someone's rear lights can give a false sense of security and is dangerous.
* If the road has street lights on you probably don't need to use your fog lights.
* Be able to stop within your range of visibility. This is particularly important on motorways and dual carriageways where you’ll be travelling at speed.
* Don’t accelerate to get away from a vehicle that is too close behind you.
* Check your mirrors before you slow down.
* At a junction with limited visibility, stop, wind down the window, and listen for traffic. When you are sure it is safe to emerge, do so without hesitation. Pausing too long puts you in the path of oncoming traffic.
