An ignition interlock is a camera enabled 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.
Service providers will install, service and calibrate Ignition Interlock Systems. They will also provide training for interlock users.
Service providers must install a device for eligible participants within 10 days of the request, and provide a toll-free 24-hour emergency response number for all participants.
Participants are responsible for all costs associated with the program participation. There is a cost from the ignition interlock Service Provider for installation of the device and there is also a monthly servicing cost. Vendors have varying installation and monitoring charges. Interlock providers are required to offer the ignition interlock at 50% of their normal rental rate for customers who are on assistance. If you are on assistance, please inquire directly with the interlock provider company for the reduced rental rate..
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.
