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. The likelihood of hydroplaning increases significantly as speed increases, particularly beyond 35 mph.

At this speed, the tires may not be able to displace water quickly enough to maintain contact with the road surface, causing the vehicle to slide over the water instead of gripping the road. This makes it critical for drivers to be especially cautious in wet conditions when traveling at higher speeds.

While hydroplaning can occur at lower speeds, the risk becomes more pronounced at or above 35 mph, which is why this speed is often cited as a threshold for heightened caution.
