Ignition Interlock Devices

More and more prosecutors are seeking mandatory installation of ignition interlock devices as a penalty for driving under the influence or driving on a suspended license following a DUI conviction. 

When an ignition interlock device is installed in a vehicle, the driver must blow into the device before the car will start.  If the driver blows a BAC that is above the legal limit, the car will not start.  After the starting the car, the driver will be required to blow into the device again at random times.  This is to prevent someone else from blowing into the device on behalf of the driver, and then the driver getting into the car to drive away.  If the driver fails the second breath test, the device will log the failed result and then start up an alarm system (usually flashing lights, honking horn, etc.) until the driver finally turns off the car and a clean breath sample has been provided. It should be mentioned that the device will not shut down the engine once it has already been turned on, as that could cause an accident or a dangerous situation. Instead, the alarm system will continue to go off until the driver turns off the engine.  The device can only prevent someone from turning on the engine.

Every time a driver blows into the device, a log will be kept of the results.  This log is sent to the police department.  If the log indicates that a driver blew above a certain percentage (a percentage pre-determined by the judge or prosecutor, usually .03 or .04 percent or more) the police and prosecution have the right to seek additional penalties.
