Abstract: The present disclosure relates to a method for operating a motor vehicle, wherein current position data of the motor vehicle is detected by at least one sensor device inside the motor vehicle, and a current position of the motor vehicle is determined based on the position data. A check is made as to whether a current occupancy condition exists for the current position, and, if so, an authorization data record is generated depending on the current occupancy condition. The authorization data record is transmitted by a communication link from a transceiver of the motor vehicle to a server device external to the motor vehicle, where a check is made as to whether an occupancy authorization certificate for the motor vehicle can be generated based on the authorization data record. If so, the occupancy authorization certificate is ultimately generated based on the authorization data record.
