A driver alertness monitoring system for motor vehicles which issues visual or audible signals to the driver, and which monitors visual, audible or mechanical responses received from the driver to determine driver alertness. An electronic control unit, preferably incorporated in the circuitry of existent vehicle safety systems, controls the activation of these visual or audible signals and determines appropriate actions based on the response of the driver. The system includes auxiliary sensors which can be used to control and modify the function of the system to reduce unnecessary activation.
