An ignition interlock assembly (74), including an ignition interlock device (10) and a logic circuit controller (68), ensures that a vehicle equipped with assembly (74) and a start-stop functionality will maintain the normal operation of the vehicle even in the event that a failed rolling retest (50, 52b) occurs when the start-stop functionality is engaged. The controller (68) preferably includes a pair of normally-opened, interconnected relays which remain energized throughout the operation of the vehicle.
