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.: 2.5.01-211
Warum sind Kurzstreckenfahrten mit kaltem Motor besonders umweltschädlich?

Weil bei Fahrten mit kaltem Motor
- der Materialverschleiß größer ist
Engine oil lubricates optimally only at certain temperatures. Until then, there is an increased material wear.
- die Fahrzeugbatterie überladen wird
The vehicle battery is not overloaded during short journeys.
- mehr Kraftstoff verbraucht wird
When the engine is cold, wear and internal resistance are higher and the catalyst is not working properly.
