Wet brakes can cause crashes. They might not work as well in a quick stop and could cause the vehicle to pull to one side, causing you to lose control of the vehicle. After driving through a large puddle of water or a car wash, lightly apply the brake pedal until the brakes work normally.
Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water.
