System and method for positively identifying an operator through biometric means which shall prevent unauthorized or impaired operation of a motor vehicle by requiring the potential operator to sequentially energize several vehicle devices, within a set time period, prior to placing the vehicle ignition into a start position. The system includes a device for measuring an operator's biometric identification, and a microcontroller. Logic outputs from the sequencing mechanism and the timer mechanism are contained within the microcontroller operating as a logic decoder that is used to control the vehicle ignition circuit. The microcontroller monitors the sequence in which the vehicle's devices are energized, and if they are energized within the correct order and within the predetermined amount of time then the microcontroller will output a signal to allow the ignition circuit to close. A sensory indicator may alert the potential operator as to the condition of the microcontroller output. An unauthorized user is inhibited from operating the motor vehicle because their identification could not be biometrically established and/or the performance sequence is unknown to him/her. Slower reflex times or impaired motor skills may also prevent an impaired operator from performing the proper sequence within the predetermined time period.
