When rain causes very slippery conditions, what should you do if your car starts to hydroplane?

Brake hard and continue driving
Keep the steering wheel steady and ease off the accelerator
Hold onto the steering wheel and increase the acceleration
Rapidly turn the steering wheel in the same direction as the slide

The correct answer is: Keep the steering wheel steady and ease off the accelerator

When driving in slippery conditions where your car may hydroplane, it is important to keep the steering wheel steady and ease off the accelerator. Braking hard can cause you to lose control and increase the risk of sliding or spinning out. Holding onto the steering wheel and increasing acceleration can also worsen the hydroplaning and lead to loss of control. Rapidly turning the steering wheel in the same direction as the slide is also not recommended as it can cause the car to spin out or make the hydroplaning worse. The correct action is to maintain a steady steering wheel and gently ease off the accelerator until you regain traction and control of your vehicle.
