The explanatory texts for the questions were machine translated. More info

All explanatory texts were compiled in German and then machine translated. This may result in translation errors. However, this only refers to the explanations to the questions. The translations of the questionnaires were done by TÜV | DEKRA arge tp 21 and are exactly the same as the translations in the theory test. These translations are only available once you are logged in. All other translations on the website were done by a different translation agency.

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.
