What is the correct action for a driver if they hydroplane?

When a driver experiences hydroplaning, which occurs when water causes the tires to lose contact with the road, the appropriate action to take is to ease off the gas pedal and steer straight. This response is vital because hydroplaning reduces a vehicle's traction, and applying the brakes or making sudden steering movements can lead to a loss of control. By gently easing off the accelerator, the driver allows the vehicle to slow down gradually, which helps to restore tire traction with the road surface. Maintaining a straight steering direction further promotes stability and control until the vehicle regains traction.

In contrast, pressing the brakes firmly can cause the vehicle to skid, as sudden braking during hydroplaning can lead to a complete loss of control. Steering sharply could also result in a spin if the tires suddenly regain traction, which can be equally dangerous. While turning on hazard lights and slowing down could be part of a broader safety protocol when dealing with adverse conditions, it does not specifically address the immediate reaction needed during hydroplaning, which is primarily about managing throttle and steering inputs.
