The car has an electronic lock (3), especially an ignition lock, and an associated electronic key (2). The key exchanges at least one coded operation signal with the lock so that after positive evaluation of the transmitted signal (9), the clearance of the car for travel operation can be released. With the attainment of a limiting value concerning the travel operation, the clearance of the car can be blocked. A preferably coded clearance signal can be transmitted to the car and/or key from an external central station spatially separated from the car. By the clearance signal, a change of the limiting value can be released. |
