When is hydroplaning most likely to occur?

Hydroplaning is most likely to occur during the first few minutes of light rain. This happens because the initial rainfall creates a thin layer of water on the road surface, which mixes with any oil and debris that may have accumulated on the pavement. This layer reduces the friction between the tires and the road, making it easier for the vehicle to lose traction and begin to glide on top of the water, rather than making proper contact with the surface.

While hydroplaning can occur during heavy rain, the risk is particularly acute at the start of rainfall when roads are slick due to the buildup of contaminants. On well-maintained roads, the risk can still be present, especially if they have low spots where water can accumulate, but it doesn't compare to the initial rainfall scenario. On dry pavement, there is no standing water to create conditions that lead to hydroplaning; therefore, the risk is significantly diminished.
