Abstract: The vehicle rear occupant alert system provides alerts corresponding to occupancy of rear seats. The system comprises a door position sensor, an ignition sensor, and an alert system. Further, the alert system comprises a processor and a memory. The door position sensor determines a rear door status between an ajar position and a closed position. The ignition sensor determines an ignition state between an ON state and an OFF state. The alert system is coupled with the sensors. The processor adjusts status of the alert system as armed if the rear door transitions from ajar to closed position and the ignition transitions from OFF to ON state. The alert system notifies and alerts a driver to check the rear seat when the ignition transitions to OFF state. The processor rearms the alert system after the ignition transitions from OFF to ON state within a predefined time.
