APPARATUS AND METHOD FOR CONFIRMING IDENTITY OF INDICATED OPERATOR OF VEHICLE ALCOHOLIC NON-SMELL INTERLOCK

摘要

A sobriety interlock system prevents a vehicle or other equipment from being started unless the identity of a designated operator is confirmed by the system by means of at least one act prescribed by the system and carried out by the operator upon the system and the operator passes a breath sobriety test. The designated operator is trained to perform a physical act, the successful completion of which is determined by the system and which requires at least a predetermined number, N, of attempts to learn. A necessary precondition for starting the vehicle is satisfied when the system determines that the identity-confirming act has been performed in fewer than N attempts.
