If you skid while hydroplaning, you should:

When you experience hydroplaning, the correct action to take is to release the accelerator. This allows the vehicle to slow down gradually and regain traction with the road. When hydroplaning occurs, water builds up between the tires and the roadway, causing a loss of control. By easing off the accelerator, you reduce the speed and help the tires reconnect with the pavement, which is crucial for regaining control of the vehicle.

Choosing to steer into the skid can sometimes be appropriate in controlling a vehicle that is already skidding, but it's generally more effective to stabilize your speed first. Applying the brakes firmly may cause the wheels to lock up, which can worsen the loss of control during hydroplaning. Turning the wheel sharply can lead to further instability and skidding. Prioritizing the release of the accelerator helps mitigate the situation, making it the best choice in this scenario.
