A safety function module (100) for a vehicle (10) is provided. The safety function module comprises a status determination unit (105) which is configured to determine at least a position of the vehicle (10). Thereby, the safety function module (100) is configured to be reversibly coupled with a signal interface (20) of the vehicle (10) and is further configured to execute a comparison of the determined position of the vehicle with a predeterminable position range and to transmit an activation signal for a safe state of the vehicle to the signal interface if the position of the vehicle departs from the predeterminable position range. As the safety function module is functionally separated from the remaining components of the vehicle, the extent of possible interdependencies of the safety functions with other components of the vehicle may be reduced or eliminated.
