The mechanical vehicle, which is used for practical driving training, does not have a corresponding recognition mark.✓Richtige Antwort
Fuel level indicator does not work.

A vehicle used for practical driving instruction must display the prescribed recognition mark so other road users can identify its special use. A fuel-level gauge only reports the remaining fuel; failure of that indicator alone does not remove required control or safety equipment and does not prohibit operation.
