Hydroplaning occurs when tires lose contact with the road due to water. Which practice helps reduce the risk?

• A. Hydroplaning is a myth; no risk.
• B. Hydroplaning occurs when tires gain grip on water; reduce risk by turning sharply.
• C. Hydroplaning is when wind lifts the car; reduce risk by speeding up.
• D. Hydroplaning occurs when tires lose contact with the road due to water; reduce risk by slowing, avoiding sudden movements, and ensuring good tire tread.

Answer: (D)

Hydroplaning happens when a thin film of water builds between the tire and the road, causing the tires to lose contact and traction. The way to reduce the risk is to slow down on wet surfaces, avoid abrupt steering, braking, or accelerating, and ensure tires have good tread depth and are properly inflated. Slower speeds give tires more time to push water out from under them and maintain grip, while smooth inputs help keep the tires in contact with the road. Good tread helps channel water away and maintain traction. The other ideas—saying hydroplaning doesn’t occur, claiming it happens when tires gain grip on water, or suggesting speeding up to prevent it—do not reflect how hydroplaning works or how to prevent it.
