Which factor increases the risk of hydroplaning?

Hydroplaning occurs when a vehicle's tires lose contact with the road surface and instead ride on top of the water layer, which can lead to loss of control. Wet road conditions combined with worn tires create the ideal scenario for hydroplaning.

When tires have inadequate tread depth, they struggle to channel water away from the tire-road interface. This inability to maintain proper contact with the road increases the likelihood of the vehicle skimming over water instead of gripping the wet surface. As a result, worn tires in wet conditions dramatically raise the risk of hydroplaning, making it crucial for drivers to ensure their tires are in good condition, especially during rainy weather.

The other scenarios presented do not contribute to an increased risk of hydroplaning. For instance, well-maintained tires with good tread help prevent such incidents, while lower speeds allow for better traction and control. Driving during daylight provides better visibility but does not directly affect hydroplaning risks.
