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.

Umweltschutz
Grundstoff, Mofa

Was sollten Sie tun, um die Umwelt zu schonen?

Ich sollte
- beim Fahren möglichst den oberen Drehzahlbereich ausnutzen
Driving in the higher rpm range burns more fuel. As a result, the environment is unnecessarily burdened.
- bei starkem Rauch aus der Auspuffanlage das Kraftfahrzeug überprüfen lassen
If heavy black smoke comes out of the exhaust, this can be caused by soot particles that accumulate in the exhaust when driving slowly or while idling and are blown out when driving faster. Heavy smoke can mean, among other things, that the engine gets insufficient oxygen for a clean burning. This may be due, for example, to a dirty air filter that should be replaced.
- bei längerem Warten den Motor abstellen
This does not unnecessarily waste fuel and expel exhaust gases into the environment.
