Abstract:
1. A self-contained system for determining impairment of a vehicle operator comprising: an ignition starting device to initiate starting of the vehicle; an electrical source to provide electrical power the system; an input to allow a potential driver to initiate a driver impairment test; a random pattern generator to generate a random pattern for testing a neuro-motor ability of the potential driver; a plurality of lights for displaying the random pattern by illuminating the plurality of lights in the random pattern; a user input to allow the user to replicate the generated random pattern simultaneously with displaying of the random pattern to test the potential driver's rapidity of visual neuro-motor response; a processing device for controlling the system and comparing data from the user input to the generated random pattern and determine if the input matches the generated random pattern; and an access preventing feature controlled by the processing device, the access preventing feature disabling the ignition starting device from initiating the starting of the vehicle unless the processor determines the user input matches the generated random pattern, the self-contained system eliminating a requirement for modifying an ignition system of the vehicle.
