Dept of Tranportation. The winter combination of overcast skies, rain and fog leads to thousands of accidents every year. In 1994 there were nearly 800 weather-related collision deaths and over 40,000 injuries on roads throughout California. Motorists can avoid many such accidents if they observe a few bad-weather driving tips. Slow down - your car needs three times more space to stop on slick roads.
Roads become slick and dangerous after a rainfall, especially early in the winter season.
Cloudy weather reduces visibility so use extra caution when passing other vehicles. Maintain a distance of six to eight seconds between your vehicle and the vehicle in front of you. Be deliberate in maneuvering your vehicle - most skidding is caused by sudden stops and turns. If your vehicle skids, don't hit the brakes. Ease off of the accelerator and steer into the direction of the skid.
