Which action should a driver take first if they start to hydroplane?

When a driver begins to hydroplane, the first action they should take is to release the accelerator. Hydroplaning occurs when a layer of water builds up between the tires and the road surface, reducing traction and causing the vehicle to slide. By releasing the accelerator, the driver allows the wheels to slow down gradually, enhancing traction as the vehicle regains contact with the pavement.

This action is crucial because maintaining or increasing speed—in situations like hydroplaning—can exacerbate the loss of control. Stepping on the brakes or steering sharply can lead to further loss of control, as these actions can cause the tires to skid. Therefore, slowly easing off the accelerator is a critical first step to recover control while navigating hydroplaning conditions.
