Reading the road - All weather driving - Fog

Fog is caused by droplets of moisture in the air. At its worst you can barely see the bonnet of your car. In these conditions it would be extremely unwise to drive.

Always use dipped headlights (or front fog lights) and high-intensity rear lights when visibility is seriously reduced.

You must remember that rear fog lights should not be used simply because it is dark, raining, or misty.

Never follow close to the tail lights of another vehicle as this would reduce your available stopping distance in an emergency.

Holding your foot on the brake pedal at junctions will keep the brake lights on; this can help drivers approaching from behind to see you sooner.

Opening your window at junctions will enable you to hear other traffic, use your horn and listen for a reply before emerging.

Keep your windows and lights clean and use your windscreen wipers and washers often.
