Pouring rain, snow melting, water condensing, fog and other natural phenomena cause the collection of water on roadway pavement, leading to the decrease of road-holding capacity of a tyre.
When a car or a light truck is moving at a high speed on wet road pavement, the water under its wheels cannot be expelled in time.
It results in raising of the front wheels of the vehicle above the road surface under the action of a hydrodynamic force and loss of vehicle control.
The methods ensuring traffic safety on road sections, where vehicle’s aquaplaning is possible, should be developed by identifying and improving these sections at the stages of highway design, reconstruction and maintenance and by limiting traffic speed of vehicles.

Keywords: vehicle, road, road-holding capacity, aquaplaning, reconstruction, maintenance, traffic safety.
