Which of the following is the best action to take if you start to hydroplane?

When a vehicle begins to hydroplane, the best action to take is to let go of the gas pedal. This is because hydroplaning occurs when a layer of water builds between the tires and the road, reducing traction and causing the driver to lose control. By easing off the accelerator, the driver allows the vehicle to slow down naturally, which can help the tires make better contact with the surface of the road as speed decreases.

Continuing to accelerate can worsen the loss of traction, leading the vehicle to slide uncontrollably. Turning the steering wheel aggressively can also lead to loss of control, as the vehicle may respond unpredictably on a wet surface. Similarly, applying the brakes abruptly while hydroplaning can lock the wheels or cause skidding, further complicating the situation. Therefore, easing off the gas pedal is the safest approach to regain control during hydroplaning.
