ABSTRACT:
A breath alcohol detection system that prevents operation of a vehicle when an operator's breath alcohol concentration is above a predetermined threshold limit or when the operator's identity is not verified. The device incorporates a breath alcohol detection device that employs an electrochemical fuel cell and an optical skin sensor that positively identifies the operator. The skin sensor is designed to sense skin on the operator's face or in the operator's mouth. Before a vehicle's starter is enabled, the operator must pass a breath alcohol test and the operator must be positively identified. If the breath alcohol test results indicate a breath alcohol concentration above a predetermined threshold, or the operator is not positively identified, the starter is disabled, thus preventing the vehicle from being operated.
