Ignition interlock in New Mexico

    Where each company can install in New Mexico

    You'll go back to the same company's locations for service for the whole order, so check that one is close to where you live and work before you book.

    Locations as each company lists them on its own locator (Smart Start, Intoxalock, LifeSafer, Low Cost Interlock, Guardian, RoadGuard), pulled Oct 2026. Some shops serve more than one company. Alcohol Detection Systems doesn't publish a locator we could read.

    Questions about interlocks in New Mexico

    How long do you have to have an interlock in New Mexico?

    It depends on how many DWI convictions you have. A first offender has the device for 1 year, a second conviction means 2 years, a third means 3 years, and a fourth or later conviction means the remainder of your life. These periods come from NMSA 66-8-102(O), as read in a bill that restates existing law.12

    Do you need an interlock for a first DWI in New Mexico?

    Yes. New Mexico requires an interlock on every vehicle driven by anyone convicted of a DWI, and that includes first-time offenders. The statute text, 66-8-102(O), calls for an interlock license and a device for 1 year for a first offender.2

    How much does an ignition interlock cost in New Mexico?

    The only state charge confirmed here is an annual Indigent Fund fee collected from DWI convicts while the device is installed. The MVD page does not state the amount. Provider installation and monthly prices are not listed either, so ask the approved providers for their current prices before you choose one.6

    Is there help paying for an interlock in New Mexico?

    Yes, through the Ignition Interlock Indigent Device Fund run by the NMDOT Traffic Safety Division. If indigency is granted and money is available in the fund, it pays up to $50 toward installation, $30 per month for verified active use, and $50 toward removal, and you pay the rest. It covers one vehicle per offender.9

    How do you get an interlock removed in New Mexico?

    The pages we reviewed do not describe a removal authorization process or form, so the steps are not covered here. What they do say is that the indigent fund covers up to $50 of removal for people who qualify for help, and you pay any remaining cost yourself.10

    What do you bring to the New Mexico MVD for an interlock license?

    Bring a lease agreement or certificate of installation, proof of insurance that lists your VIN, and an Affidavit of Ignition Interlock, which must be notarized before your appointment. If you are between 18 and 24, you also bring a 'None for the Road' certificate.11
