What should you do when your vehicle hydroplanes?

Release the accelerator
Slam on the brakes
Turn the steering wheel sharply
Accelerate to gain control

The correct answer is: Release the accelerator

Hydroplaning occurs when your vehicle loses traction on a wet road surface and slides on a layer of water. When this happens, it is important to release the accelerator and avoid any sudden or jerky movements. This is because accelerating or turning sharply can cause the vehicle to lose even more traction and increase the risk of a loss of control or a potential accident. Slamming on the brakes can also be dangerous as it may cause the wheels to lock and further decrease the vehicle's traction. It is best to ease off the accelerator and steer gently in the direction of the skid until the tires regain traction and you are able to safely slow down and come to a stop. Remember to stay calm and avoid any sudden maneuvers to avoid losing control of your vehicle.
