Heavy rains can quickly reduce your visibility and create unwelcome surface water. Taking simple precautions and knowing what to do if you get caught will help keep you safe. For example, never try to drive through flooded roads especially if you cannot see the other side. However, if you have no alternative, wait until the coast is clear (you don’t want to swamp or to be swamped by another vehicle) then keep your engine revs high and move forward cautiously in first gear until you are clear.
Remember, reversing is not an option as this will force water up the exhaust pipe and into the engine. Always test your brakes after going through water. To dry your brakes, press the brake pedal lightly while keeping the car moving about 10mph for about 100 metres.
