What is the main risk associated with hydroplaning?

Losing control of the vehicle
Increased fuel consumption
Slower acceleration
Higher tire wear

The correct answer is: Losing control of the vehicle

The main risk associated with hydroplaning is losing control of the vehicle. Hydroplaning occurs when a layer of water builds up between the tires of the vehicle and the road surface, causing the tires to lose contact with the pavement. This can lead to a loss of traction, making it difficult for the driver to steer, brake, or accelerate effectively. As a result, the vehicle may drift, skid, or spin out, significantly increasing the risk of accidents. In contrast, while increased fuel consumption, slower acceleration, and higher tire wear can be considered issues related to driving in wet conditions, they do not represent the immediate and dangerous loss of control that comes with hydroplaning. The primary concern when hydroplaning is the ability to maintain control of the vehicle, which is essential for safe driving.
