Remember also when you begin a journey in rain that your shoes will be wet and liable to slip of the pedals. Scuff the soles on the rubber matting or carpetting of the car before you start the engine. Visibility Wipers will often clear light rain from the windscreen with a few sweeps, then run on an almost-dry screen and leave smears of drying dirt. Use the wind washers liberally and operate the wipers in short, frequent bursts. Heavy rain, on the other hand, can overload the wiper blades, allowing an almost continuous sheet of water to flow over the screen.
Rain can also cause windows to mist up inside the car.
The windscreen is easily cleared by the de-mister, by fresh air or by the use of an impregnated cloth. If the car has swivelling fascia vents, adjust them so that the air flow strikes the upper edge of the side windows and the moves along the side windows to the rear of the car. When tyres are waterborne, steering control is lost. Reduce speed by easing the accelerator. Do not breake until tyre is re-established Whenever it rains, a film of water forms on the road.
