Hydroplaning refers to a situation where a vehicle's tires lose contact with the road surface due to a layer of water that builds up between the tires and the road, resulting in a loss of traction. This phenomenon typically occurs when a vehicle is traveling at high speeds over wet surfaces, particularly when there is standing water on the roadway. When hydroplaning happens, the driver may feel as though the vehicle is gliding or sliding, making it difficult to steer or control the vehicle effectively.

Understanding hydroplaning is crucial for safe driving, especially in rainy or wet conditions; it highlights the importance of maintaining appropriate speed and tire maintenance to reduce the risk of losing control when driving on slick surfaces. Options such as techniques to improve traction, specific tire treads, or maneuvers in heavy rain do not accurately capture the essence of what hydroplaning involves.
