We strongly suggest that you notify your installer before performing vehicle maintenance, service or repairs that would involve starting or driving your vehicle or disconnecting the battery. Your auto repair technician can contact your installer for specific instructions on how to avoid recording erroneous violations.
The vehicle will not start and the IID will enter a short lockout period of a few minutes. This lockout period allows an opportunity for the alcohol to dissipate from the mouth and for you to consider the reason for the failed breath alcohol test, for example; is the failure a result of the use of mouthwash, cough syrup, etc., or as a result of consuming too much alcohol. The IID will record the failure, which will be noted in the data report. If you make 3 attempts to start a vehicle with a BAC of .04 or above, your IID requirements will be extended for a period of 3 months.
The device will give you a reminder 7 days prior to a scheduled service date, followed by a warning to obtain service within 5 days. If you fail to bring your vehicle to the installer for service within those 5 days, the IID will place your vehicle in a permanent lockout state; the vehicle would have to be towed to the installer for service before you can operate it again. Failure to bring your car in for service will result in an extension of your RDL requirements.
The IID collects and stores the information below, which is reported to the Department of Motor Vehicles and the Department of Corrections. This information is also provided to Project CRASH.

An Ignition Interlock Device, referred to as an “IID”, is an after-market device which is installed in a vehicle. The IID is connected to the starter or ignition, or other on-board computer system of a vehicle. The device prevents a driver from operating the vehicle if the driver has been drinking. Before starting the vehicle, a driver must blow into the device; if the driver’s BAC is at or over a pre-set limit, 0.02 in Vermont, the IID will not allow the vehicle to start. Once the vehicle is started, at random times during the operation of the vehicle, the device will prompt the driver
