What is the best way to prevent hydroplaning while driving in the rain?

Driving at a speed of less than 35 mph in heavy rain is considered the best approach to prevent hydroplaning. Hydroplaning occurs when a layer of water builds up between the tires of the vehicle and the road surface, which can cause a loss of traction and control. By reducing speed, especially in wet conditions, a driver increases the tire's contact with the road, allowing for better handling and braking response.

Under heavy rain conditions, reducing speed helps to mitigate the likelihood of water accumulating under the tires, thus decreasing the chances of hydroplaning. It is essential to recognize that the effectiveness of tires in channeling water away from the road surface decreases as speed increases, making slower speeds more effective in maintaining control.

While other potential strategies are present in the choices, they do not align with the fundamental principles of safe driving in adverse weather conditions. Maintaining maximum tire pressure does not account for the fact that tire tread and design play critical roles in water drainage. Likewise, driving at significantly higher speeds, as suggested in the higher options, increases the risk of hydroplaning due to decreased tire-road contact.
