define when a driver is required to have the ignition interlock restriction on a license after certain convictions or affidavits.
Connected to a vehicle's ignition system, an ignition interlock device requires an individual to breathe into the equipment, which prevents the vehicle from starting if the individual's breath alcohol concentration is outside the acceptable range.
Ignition interlock devices are installed at the expense of the driver.
The N.C. Division of Motor Vehicles can waive ignition interlock installations on additional vehicles for applicants who meet household income criteria and have submitted an DMV Interlock Hardship with their written hearing request. The form is also available in
Effective June 1, 2022, a person who is ordered by a court, or required by statute, to install an ignition interlock system to lawfully operate a motor vehicle, but who is unable to afford the cost of an ignition interlock system, may apply to an authorized vendor for a waiver of a portion of the costs of an ignition interlock system. A person who applies for a waiver of the portion of the costs of an ignition interlock system shall provide the completed Vendor Interlock Hardship to an authorized vendor.
