Following the conviction of your first DUI offense, the court may order that an ignition interlock device be installed on your vehicle. It is installed into your vehicle’s ignition and contains a breathalyzer attachment. Very simply, you must breath into the breathalyzer with a BAC limit less than .025 in order to start your car.

The limit is very low, less than a third of the legal .08 limit. In fact, authorities advise drivers not to eat or smoke before attempting to start their vehicles. It is a device that seems effective in concept, but pales when you consider that merely smoking a cigarette or eating too soon before you start your car could prevent you from “driving under the influence”.
