A "breath test" device that is attached to your car or vehicle which requires you to blow into it in order to start your car. You must register less than .02 BAC for the device to allow the ignition to unlock. As of 1/1/06, "Melanie's Law" requires that anyone who wishes to get his/her Massachusetts driver's license reinstated after a Second Offense OUI conviction must have one of these devices installed in his/her car. The Registry of Motor Vehicles is unfortunately applying this rule even to those whose convictions predated the passing of Melanie's Law on 10/29/05, and would not have foreseen this burdensome penalty.
