An IID is a breath test device that is installed in your personal vehicle. It requires the driver to blow into a device each time the vehicle is started. It also requires regular re-testing of the driver while the vehicle is in motion. The device must be installed by an approved vendor at a cost of approximately $100. The device must be maintained at a monthly cost of approximately $100.

If you are convicted of any misdemeanor or felony DWI, pursuant to DMV rules, an IID will be required to be installed in your vehicle.  For a misdemeanor, the IID will be ordered for one year, but you can seek a court order for the removal of the IID after 6 months.  For a felony DWI conviction, the IID will need to remain on your vehicle for at least a year.
