Hydroplaning refers to the phenomenon where tires lose traction because they are riding on a layer of water instead of making direct contact with the road surface. This typically happens during wet conditions when there is more water on the road than the tires can displace. The result is a significant reduction in traction, which can lead to a loss of control over the vehicle, making it crucial for drivers to recognize and respond to these conditions appropriately.

Understanding this concept is important for safe driving, especially in adverse weather conditions, and emphasizes the need for proper tire maintenance and pressure, as well as reducing speed in wet conditions to mitigate the risk of hydroplaning.
