Night, weather, skids, vehicle failures and collisionsStandalone practice
When driving in heavy rain, your tires may ride on a thin layer of water rather than the road surface, causing a total loss of traction. This is known as:
Blue A travels on a wet road. An enlarged cutaway below shows a tyre above a water film over the road. The detail is separate from the road scene and is not drawn to scale. No name for the phenomenon is shown.
Correct answer: Hydroplaning
Why
Hydroplaning occurs when water builds up in front of your tires, and your vehicle lifts off the road surface, riding on a film of water. You lose all steering and braking ability.
