The heavier the rain, the harder is to see. Evenif your it windshield wiper blades arein good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, theedge of the road and even people walking. It's wise to keep your wiping equipmentin 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. Driving too fast through large water puddles or even going through somecar washes can cause problems, too. The water may affect your brakes. Try to avoid puddles. But if you can't, try to slow down before you hit them. Wet brakes can cause accidents. They won't work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle. After driving through a large puddlewater or of a car wash, apply your brake pedal lightly until your brakes work normally.
