How can hydroplaning be prevented?

1. By driving at high speeds

2. Using anti-lock brakes

3. Pumping your brakes

4. Driving with your windows down

The correct answer is: Pumping your brakes

Pumping your brakes is a technique that can help maintain control of the vehicle during a hydroplaning situation. When a vehicle hydroplanes, it loses contact with the road surface due to water buildup between the tires and the road. Pumping the brakes can help the driver regain traction by allowing the tires to make brief contact with the pavement, reducing the likelihood of losing control. This method is particularly useful in managing speed and re-establishing control without causing the wheels to lock up and increasing the chances of skidding. Driving at high speeds increases the risk of hydroplaning, as vehicles are more likely to lose contact with the road surface when there is a substantial amount of water. Using anti-lock brakes can help prevent skidding during braking, but it does not directly address the issue of hydroplaning itself. Finally, driving with your windows down has no effect on hydroplaning prevention, as it does not influence the vehicle's traction with the road. Therefore, pumping the brakes is the most effective method to manage hydroplaning and maintain vehicle control.
