An ignition interlock is a device that connects a motor vehicle's ignition system to a breath analyzer that measures a driver's breath alcohol level and prevents a motor vehicle from starting if the driver's breath alcohol level exceeds the setting on the device.  After starting the car, random retests are required to be certain the driver has not consumed alcohol.

Participants are responsible for all costs associated with the program participation.  Participants are required to report to a service provider every 30 days to have the device calibrated and the data logger information downloaded.

The data logger keeps a record of every transaction, along with the date, time, and alcohol level, any efforts to disable or circumvent the unit and random retest compliance.  This information is reported to the appropriate monitor.
