ABSTRACT:
An automotive device for inhibiting engine ignition in response to operation of an ignition switch in a manner inconsistent with a prescribed routine which varies unpredictably. The device has two operational modes for impairment detection and theft deterrence, the respective modes being enabled by a plurality of switches. A gauge warning light is energized in response to the ignition switch being turned to a first active position. After a variable interval of time the gauge warning light dims. Following the initiation of dimming, the operator must turn the ignition switch to a second active position within a "window of time", whereby the operator's reflexes and concentration are tested. Failure of the operator to turn the ignition switch within the "window of time" results in disablement of the starter.
