Driving in Rain and on Wet Roads And, if your tires don't have much tread left, you'll get even less traction. It's always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement. The heavier the rain, theharder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can makeit harder to see road signs and traffic signals, pavement markings, the edgeof the road and even people walking. It's wise to keep your wiping equipment in good shape and keep your windshield washer tank filled with washer fluid. Replace your windshield wiper inserts when they show signs of streaking or missing areas on the windshield, or when strips of rubber start to separate from the inserts. Rain and wet roads can mean driving trouble. On a wet road, you can't stop, accelerate or turn as well because your tire-to-road traction isn't as good as on dry roads. 4-16
