South Carolina Driver's Permit Practice Exam

What should you do if your vehicle starts to hydroplane?

1. Turn sharply to regain control

2. Brake hard to slow down

3. Slowly take your foot off the gas pedal to allow your vehicle to slow down

4. Accelerate lightly to maintain speed

The correct answer is: Slowly take your foot off the gas pedal to allow your vehicle to slow down

If your vehicle starts to hydroplane, the appropriate response is to slowly take your foot off the gas pedal to allow your vehicle to slow down. Hydroplaning occurs when there is a layer of water on the road that prevents your tires from maintaining contact with the pavement. This loss of traction can lead to a loss of control. By easing off the accelerator, you give your vehicle a chance to regain traction as it slows down. This gradual reduction in speed helps to stabilize your car and allows the tires to re-establish contact with the road. It is important to avoid sudden maneuvers or harsh braking, as these actions can exacerbate the hydroplaning effect and lead to skidding. Maintaining calm and control by gently reducing speed is the safest course of action.
