Which of the following statements about hydroplaning is true?

Correct answer

  • Hydroplaning decreases at high speeds.
  • Hydroplaning can occur on unpaved roads.
  • Partial hydroplaning can start at about 35 mph.


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.? It may result in a loss of braking and steering control. To prevent hydroplaning, slow down.
