Driving in Fog

You must take great care when driving in fog, as it drifts rapidly, which means that conditions can change dramatically within just a few seconds. To minimize the risks, follows these guidelines:

• Drive slowly and keep an eye on your speedometer - fog creates a visual illusion of slow motion when you may in fact be speeding.
• Make sure that you are visible to others by using your dipped headlights. Do not use high beams as they will be reflected back off the fog, impairing visibility even more.
• If visibility is seriously reduced (less than 330 feet), use your foglamps. However, you must turn them off as soon as conditions improve, as they can mask your stoplamps and dazzle the drivers following you, increasing the risk of a rear-end collision rather than reducing it.
• Listen for traffic you cannot see; you can do this by opening the window a little, to hear better.
• Make sure that you leave plenty of space between you and the vehicle in front. It can be tempting to hang on the tail-lights of another vehicle; however, this can give you a false sense of security, and can lead to you getting too close to that vehicle.
• Use the right edge of the road or painted road markings as a guide.
• If the fog appears to be clearing, don't assume that it has completely gone and so increase your speed. Fog can frequently be patchy, and you could suddenly find yourself back in thick fog.
