Why does opening a rear emergency door while the vehicle is in motion usually trigger an alarm or buzzer?

1. It is purely a security feature to prevent theft when parked

3. To warn the driver immediately that an exit not meant for regular use has been opened while moving
4. It signals passengers that the vehicle has reached its final stop, using the same buzzer as the regular stop-request system
