Due to significantly reduced friction between the tyres and road surface the above stopping distances are multiplied by 2 for stopping distances in rain. Stopping distance in rain. With correct parameters its a perfect equation for an accurate calculation of the stopping distance of your car.
How much stopping distance. This image from the Highway Code gives you an idea of average stopping distances according to speed The average car driving at 20 mph will travel 20 feet before coming to a complete stop however a car travelling at 40 mph will take 80 ft to come to a stop.
