Where does aquaplaning (sliding on wet roads) occur particularly often?

Aquaplaning occurs when a layer of water builds up between the tires and the road surface, causing a loss of traction. It happens especially often in dips in the roadway because water collects in these lower areas. It also frequently occurs where there are grooves or ruts in the roadway, as water accumulates in these channels, increasing the risk of sliding. Level crossings are not especially prone to aquaplaning because water typically does not pool there in the same way. If you see water collected in dips or in ruts, reduce your speed to lower the risk of aquaplaning.
