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.

Was soll man beim Tanken beachten?

Nicht nachtanken, wenn der Tank voll ist und die Zapfpistole abgeschaltet hat
The fuel comes out of the tank at 6 - 8 ° C and has a certain volume according to this temperature. If the outside temperature is higher, the fuel in the tank immediately starts to heat up. This increases its volume. When the fuel nozzle stops, there is still enough air in the tank, which can escape as the fuel expands. I fill up to the brim, then this air cushion is missing. The fuel expands and the part that no longer fits in the tank exits. This does not comply with environmental and fire protection regulations. Refueling should therefore be avoided.
Keine Kraftstoffdämpfe einatmen
The inhalation of fuel vapors may cause damage to health or disruption of information processing in the brain. Therefore you should rather do without it.
