Final answer:
To prevent hydroplaning, you should slow down.
Step-by-step explanation:
Hydroplaning occurs when tires ride on a thin film of water instead of the road. To prevent hydroplaning, you should slow down. This allows more of the tire's tread to make contact with the road, which helps to displace the water and maintain traction. Slowing down reduces the likelihood of hydroplaning and allows you to maintain control of the vehicle.
