Under what conditions can your vehicle hydroplane?

Hydroplaning occurs when a vehicle's tires lose contact with the road surface due to a layer of water, causing the vehicle to slide uncontrollably. The correct answer highlights that this can happen at speeds of 30 mph or greater on wet roads. At these higher speeds, the tires are unable to effectively displace the water, resulting in a loss of traction.

The phenomenon is more likely to occur when the water depth is sufficient to prevent the tires from making firm contact with the pavement. Factors such as tire tread depth and road conditions can exacerbate this effect, but the critical speed threshold of 30 mph identifies when the likelihood of hydroplaning increases significantly.

Other scenarios presented in different choices, while they may seem relevant, do not accurately describe the conditions under which hydroplaning typically occurs. For instance, icy road surfaces or heavy traffic might contribute to loss of control in different ways but do not specifically relate to hydroplaning in the same context. Similarly, while worn tires can increase the risk of hydroplaning, the speed factor on wet roads remains the primary risk for hydroplaning incidents.
