Explanation
Hydroplaning is when a car's tires lose contact with the road due to standing water on the roadway. At speeds of up to 35 mph, most tires will channel water away from the tire, but as the speed increases, the tires cannot channel water as well, and partial hydroplaning can occur. This means that at speeds as low as 35 mph, a car's tires may start to lose contact with the road and ride over the water like a set of water skis. It's important to maintain good tires with adequate water-channeling tread on your vehicle and slow down when there is water on the roadway to prevent hydroplaning.
