When a vehicle begins to hydroplane, it means that the tires have lost contact with the road surface due to water on the pavement, usually during rainy conditions. The correct response is to slow down until contact with the road surface is reestablished.

Reducing speed allows the tires to regain traction as the vehicle slows down, and the water can disperse from under the tires. This action helps the driver to regain control of the vehicle, reducing the risk of accidents caused by skidding or losing control entirely. Hydroplaning can occur at any speed, but the risk increases with higher speeds, which makes it crucial to manage your speed appropriately during such conditions.

The other options encourage behaviors that would exacerbate the problem. Speeding up or maintaining the same speed while hydroplaning will result in continued loss of control, while accelerating might prevent the tires from regaining adequate contact with the surface, further increasing the risk of sliding or crashing.
