Final answer:
Hydroplaning occurs when a layer of water builds up between the tires of a vehicle and the road surface, causing the tires to lose traction and making it difficult for the driver to control the car.
Step-by-step explanation:
Hydroplaning occurs when a layer of water builds up between the tires of a vehicle and the road surface, causing the tires to lose traction. This can happen when the road surface is wet due to rain, snow, or ice. When the tires cannot grip the road properly, it becomes difficult for the driver to control the car, increasing the risk of accidents.
For example, when a light rain falls, the oil and gasoline that have leaked onto the road surface from cars can mix with the water, creating a slippery layer that reduces the control of the car.
A heavy rain can exacerbate the problem by making the road surface even more slippery and increasing the depth of the water layer, further reducing the traction between the tires and the road.
