In heavy rain, your tires can ride on a film of water and lose contact with the road. This hazard is known as

Explanation

On a wet road, at speeds of up to 35 mph, modern tires will usually channel water away to maintain contact with the road. However, in deep water at higher speeds, the channeling action of the tires becomes less effective and the tires start to ride on a layer of water like water skis. This is called "hydroplaning." At 50 mph or above, hydroplaning may result in a total loss of braking and steering control. To prevent hydroplaning, make sure your tires have enough tread, keep them properly inflated, and slow down. And always increase your following distance in wet weather.
