Detailed description
Vehicles that do not require registration need a vehicle registration certificate (Betriebsgenehmigung) to be issued an official license plate or an insurance license plate. If the vehicle registration certificate is no longer available, a replacement certificate must be requested from the manufacturer.
To do this, you must first apply for a certificate of no objection from the state transport authority. This certificate confirms that no vehicle defects are known and that the vehicle's operating permit has not been revoked by the registration authority. The manufacturer or an officially recognized expert can then issue the replacement operating permit.
