Which of the following can increase the likelihood of hydroplaning?

Hydroplaning occurs when a layer of water builds up between the tires of a vehicle and the road surface, leading to a loss of traction and control. Driving on wet surfaces significantly increases the risk of hydroplaning because water creates a potential for the tires to lose direct contact with the road. When the road is wet, especially if there is standing water or heavy rain, the tires may not be able to displace the water quickly enough. This situation can lead to skidding and decreased vehicle control, contributing to the likelihood of hydroplaning.

While the other options may relate to driving conditions, they do not create a heightened risk of hydroplaning in the same way that wet surfaces do. Paved roads typically offer better traction than unpaved surfaces, and driving at lower speeds actually helps reduce the risk of hydroplaning since it allows for better tire contact with the road. Using cruise control in wet conditions can be dangerous because it may encourage drivers to maintain speed without adjusting for changing road conditions, thus increasing the risk of losing control if hydroplaning does occur.
