Hydroplaning occurs when:

• A. Your tires lose contact with the road
• B. Your brakes fail
• C. You are going downhill
• D. The road is icy

Answer: (A)

Hydroplaning occurs when your tires lose contact with the road due to a layer of water between the tires and the road surface. This phenomenon typically happens when driving on wet roads, especially during heavy rain, where the water can create a barrier that prevents the tires from gripping the road effectively. When hydroplaning occurs, steering and braking become much more difficult, as the vehicle can slide uncontrollably, leading to a higher risk of accidents.

The other options relate to different driving hazards but do not capture the specific scenario of hydroplaning. For example, brake failure can lead to loss of control, but it does not specifically involve the relationship between tires and water on the roadway. Similarly, going downhill increases the speed of the vehicle and may lead to loss of control, but it is not a direct cause of hydroplaning. Lastly, icy roads can create slippery conditions, but hydroplaning is specifically related to water accumulation on the road surface, not ice. Therefore, the accurate description of hydroplaning is that it happens when your tires lose contact with the road.
