What causes hydroplaning while driving?

Hydroplaning occurs when a layer of water accumulates between the tires of a vehicle and the surface of the road. This layer of water creates a barrier that prevents the tires from maintaining proper contact with the road. As a result, the vehicle can lose traction and slide uncontrollably, which can make steering and braking ineffective.

While other factors can also contribute to the risk of hydroplaning, the primary mechanism is the presence of water on the road that interferes with the tires' grip. Having adequate tire pressure, tires in good condition, and driving at safe speeds can help reduce the likelihood of hydroplaning, but the critical factor is the amount of water that creates that slippery layer.
