Abstract: The invention relates to a system for the monitored signalling of a vehicle state, in particular for the monitored signalling of an activated, at least partially automated, driving operating state of a motor vehicle and to a method for the automatic monitoring of a vehicle state-signalling device. Specifically, the invention relates not only to the system and to the method but also to a monitoring device for carrying out the method, to a computer program which is configured to execute the method and to a vehicle state-signalling device and to a vehicle, in particular to a motor vehicle, equipped with the system. In the method, a first control signal, which is configured to change an assigned signal encoder of the vehicle state-signalling device into a deactivated state, is transferred to the vehicle state-signalling device. Testing of a current actual operating state of the signal encoder is then carried out.
