An electrical system for providing an audible or visible warning and interior and exterior visible displays indicating whether the occupants of a motor vehicle have fastened their seat belts, in compliance with legal requirements and/or the will of the driver. The system involves a plurality of circuits each of which is associated with a driver's seat sensor switch, with a seat belt latch and with an interior display panel, and at least some of which are also associated with exterior display lights. Each said circuit has a seat belt latch for closing or opening said circuit, when the driver's seat sensor switch is closed, to change the condition of a light at a corresponding position on the interior display panel and, for at least the front seat belts, to change the condition of a corresponding exterior display light. The system also includes a warning circuit including an audible or visible warning signal which is activated when the driver's seat sensor switch is closed and the ignition is turned on, and can only be deactivated by the driver latching his or her seat belt.
