A system for detecting a child, pet or other occupant left in the back seat 104 of a motor vehicle. The system comprises a first sensor 112 coupled to a back seat access device such as a rear vehicle door (206, 208 fig 2), a second door lock position sensor 124, an audible alarm device 128, a processor 114 and a memory device (350, fig 3). The system is operable to evaluate signals from the first door access sensor to determine whether an occupant remains within the vehicle. If the second door lock sensor is triggered whilst an occupant is considered to remain within the vehicle, an audible alarm device is triggered. The system may also incorporate direct occupancy sensors 118 within the vehicle, an ignition disabling device, a telematics system 130 for transmitting alert messages externally and circuitry to operate the vehicles windows in response to an alarm signal.
