ABSTRACT:
An alcohol and drug sensor system for vehicles for preventing ignition of a vehicle engine by an intoxicated driver includes a gas chromatograph sensor operationally coupled to a sample collection tube. The sensor is operationally coupled to a microprocessor that prevents the ignition system of the vehicle from working until a breath sample is collected and the intoxicant content of the breath sample is determined to be below a pre-determined level.
