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.
You should always keep your speed below the maximum speed limit for the road you are driving on. Although you are not legally obliged to drive at the maximum speed limit, if it is safe to do, you should try and drive at a speed that at least approaches it, for instance, in a 40mph zone your speed should be between 35 and 40mph. Driving too slowly can be as dangerous as driving too fast.
