In a heavy rain, tires can ride on a thin film of water, without touching the road. This is called:
|
Rainplaning.
|
|
|
Risk-planning.
|
|
|
Hydroplaning.
|
|
|
Waterplaning.
|
Explanation
Hydroplaning occurs when a layer of water on the road surface causes the tires of a vehicle to lose contact with the road. When the road is wet, most tires have good traction up to about 35 mph. However, at higher speeds, your tires will start to ride up on the water, making it difficult to accelerate, brake or turn. If it feels like your tires have lost traction with the surface of the road, ease your foot off the gas pedal and keep the steering wheel straight until you regain control of your vehicle.
