Front fog lights should be used

A when visibility is reduced to 100 metres (328 feet)

When visibility is seriously reduced, switch on your fog lights if you have them fitted. It is essential not only that you can see ahead, but also that other road users are able to see you.

To counter reduced vision, fog lights must be utilised at the appropriate times; otherwise, you may endanger yourself and other vehicles. When used correctly, they should assist in safe driving, but when used incorrectly, you may be breaching the law and endangering other drivers.

What to do if you're driving in fog:

- Before entering fog, check your mirrors and slow down.

- Keep a wider space between yours and the automobile in front of you, up to four seconds from the recommended two.

- Use your wipers and keep your windscreen clean to improve visibility.

- If a signal indicates "fog," but the road is clear, be prepared for a sudden bank of fog or drifting, patchy fog.

- Turn on your lights if visibility falls below 100 metres (328 feet), or approximately the length of a football pitch.

- Before you turn on your fog lights, make sure you know where it is.

- Avoid using maximum beam since fog reflects light back, lowering visibility even further.

- Do not attempt to navigate using the tail lights of the vehicle in front of you, since this might provide a false sense of security.

- If visibility is really restricted, roll down your windows at junctions and crossroads to allow you to hear incoming vehicles. 

- If you can't see anything, you should consider stopping until it's safe to proceed.
