The heavier the rain, the harder it is to see. Even if your 
windshield wiper blades are in good shape, a heavy rain can 
make it harder to see road signs and traffic signals, pavement 
markings, the edge of 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.
Driving too fast through large water puddles or even
going through some car 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 puddle of water or
a car wash, apply your brake pedal lightly until
your brakes work normally.
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
