Abstract
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 and the operator passes a breath sobriety test. The designated operator is trained to perform a physical act, the successful completion of which can be 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.
