Which of the following is true regarding hydroplaning?

Hydroplaning occurs when a vehicle's tires lose contact with the road surface and ride on top of a layer of water, which can happen even at relatively low speeds. The correct choice highlights that hydroplaning can occur at speeds as low as 30 mph, especially on wet roads where there is a significant amount of water accumulation.

Factors such as tire tread depth, road conditions, and the amount of water present significantly influence the likelihood of hydroplaning. When the roadway is drenched, the risk increases, leading to the potential for losing control of the vehicle. Understanding this concept is crucial for safe driving in wet conditions, as drivers should be aware that speed alone is not the sole determining factor in hydroplaning – water accumulation on the road plays a critical role as well.
