Preventing a Movement of an Autonomous Vehicle

A device for preventing a movement of an at least partially autonomously drivable vehicle in an autonomous driving mode includes an actuator where an immobilization function of the at least partially autonomously drivable vehicle is activatable or deactivatable by the actuator. The actuator is a switch accessible from outside of the at least partially autonomously drivable vehicle. Access to the actuator is controllable by an overriding safety device.
