You should reduce your speed by 1/3 on wet roads and by 1/2 or more on snow packed roads. If you would normally be traveling at a speed of 60 mph on dry pavement, then on a wet road. you should reduce your speed to 40 mph, and on a snow-packed road you should reduce your. speed to 30 mph. When you come upon slick, icy roads you should drive slowly and cautiously.
Driving in fog is another situation when an extra effort is needed to ensure other drivers see you. Remember to use low beams in fog or heavy snow. The use of high beams under these conditions results in what is called white-out. White-out is created when the high beams reflect off the fog or snow. It is nearly impossible to see when there is a blanket of white reflection in front of you. Dawn and dusk are also times when headlights are critical. At dawn, some drivers turn their headlights off at the first sign of sunlight.
