Comment

Aquaplaning - also known as hydroplaning - occurs when the tread depth of the tires is too low to displace the accumulated amount of water or when the amount of water to be discharged is too large due to a high speed (from 60 km/h). In addition, wheel ruts in the road, in which water accumulates, favor this effect.
