Frage-Nr.: 2.1.03-015
Was kann auf nasser Fahrbahn zu Aquaplaning (Wasserglätte) führen?

Aquaplaning means water smoothness. Usually the tire is stuck on the road. If there is a film of water on the surface, the tires lose their grip and the vehicle slips.
Abgefahrene Reifen
The higher the tread depth of the tires, the more space there is in the tread grooves to adhere to the road despite the water film.
Spurrillen in der Fahrbahn
On rutted roads the rippling water collects, which is distributed on flat roads over the entire road surface. Thus, the water level is also higher here and vehicles are more likely to slip due to aquaplaning.
Hohe Geschwindigkeit
The higher the speed, the more risk of aquaplaning. At low speed, the water can be pushed aside by the tires, at higher speeds, this time is missing and the car skids over the water film.
