Hydroplaning typically begins at speeds of around 35 mph on wet surfaces. This phenomenon occurs when the tires of a vehicle can no longer make contact with the road due to a layer of water between the tires and the pavement. When vehicles travel at this speed or higher on slick, wet surfaces, they risk losing traction, which can lead to a loss of control. The likelihood of hydroplaning increases as speed increases, particularly if the road is covered in standing water. Understanding this threshold is essential for maintaining safe driving practices, especially in adverse weather conditions.
