Wet road surfaces can cause tires to hydroplane (skim on a thin layer of water). This could result in loss of control and steering ability. Hydroplaning is caused by a combination of standing water on the road, car speed, and under-inflated or worn-out tires.

Cars Hydroplane

If it feels like your tires have lost traction with the surface of the road and your vehicle is hydroplaning, take your foot off the accelerator and let the vehicle slow down. Do not try to stop until your tires are gripping the road again. To reduce the chances of hydroplaning, use tires with adequate water-channeling treads and check them regularly. Remember the other important factor is speed control—always slow down when water is on the road.
