What causes hydroplaning when driving?

Hydroplaning occurs when a vehicle’s tires lose contact with the road surface, which is primarily caused by moisture, typically in the form of rain or standing water. When tires travel over a wet surface, the water can create a barrier that prevents the tires from making adequate contact with the road. This can happen when a layer of water lifts the tires off the pavement, leading to a loss of traction and control.

To maintain safe driving conditions, it is essential for tires to have sufficient tread depth to channel away water effectively. If this water cannot be displaced quickly enough, hydroplaning can occur. The phenomenon is exacerbated at higher speeds, as more water needs to be cleared in a shorter amount of time. Proper tire maintenance, including ensuring appropriate tread depth and tire pressure, is crucial in preventing hydroplaning.
