Minnesota Ignition Interlock Requirements (2026): Costs & Approved Providers

Minnesota’s IID program lets any first-offense DWI driver keep driving during their revocation — it’s the only way to drive legally during that period. For second and subsequent offenses (within 20 years for incidents on/after July 1, 2025), participation is mandatory. Three certified providers serve the state, and qualifying low-income drivers pay capped rates through the DVS reduced-fee program.

Who administersMinnesota DVS — IID Program
Governing lawMinn. Stat. 169A.20; 171.306; 171.178; 171.29 subd. 2
July 1, 2025 law change: 20-year lookback window for 2nd+ offenses. For DWI incidents on or after July 1, 2025, Minnesota counts prior offenses within the preceding 20 years to determine whether you’re a first, second, or subsequent offender — and what IID term applies. If your prior offense was more than 20 years ago, it may not count toward your offense level for IID purposes. Pre-July 1, 2025 incidents may follow different lookback rules. Confirm how this applies to your specific case with your attorney or DVS.

How Minnesota’s IID program works

Minnesota’s IID program works similarly to Iowa’s and Illinois’s: the device is how you drive during your revocation period. First offenders at a standard BAC (under 0.16%) can choose to sit out the revocation or participate — if they want to drive, the IID is the only way. At BAC 0.16% or higher, or for a test refusal, the IID is the only route to driving at all during revocation.

Second and subsequent offenders (for incidents on/after July 1, 2025 within 20 years) do not get a choice — participation is mandatory, and the minimum IID terms escalate significantly: 2 years for a second offense, 6 years for a third, and 10 years for a fourth or beyond.

Enrolled in a public assistance program? You pay reduced capped rates. Minnesota’s DVS Reduced Fee Program requires certified manufacturers to serve eligible low-income participants at capped rates — for example, $40 per service/calibration appointment including device insurance, per the 2026 certification document. Eligibility: proof of current enrollment in SNAP, Medical Assistance/Medicaid, MFIP, TANF, SSI, WIC, MinnesotaCare, General Assistance, Head Start, NSLP, EAP, CCAP, FDPIR, or MFAP via a current acceptance letter. Covers one vehicle only; must reapply yearly; not retroactive.

How to enroll — 5 steps

  1. After your DWI revocation, apply to DVS to enroll in the IID Program. If you’re a 2nd+ offender (within 20 years, incident on/after 7/1/2025), participation is mandatory — apply promptly.
  2. If you qualify for the reduced-fee program, gather your current acceptance letter from a qualifying assistance program (SNAP, MA, SSI, WIC, etc.) and present it to DVS and your provider before installation.
  3. Contact one of the three DVS-certified providers, confirm their certification, and schedule installation. Bring your DVS enrollment paperwork and vehicle.
  4. Pay the $680 DVS reinstatement fee when prompted. Serve the full IID term — keep every calibration appointment and never drive after drinking.
  5. At the end of your term, DVS issues a full reinstatement letter authorizing removal. Use an authorized service center, then apply to DVS for a license without the IID restriction.

Violations — escalating additions

Minnesota uses a tiered violation-extension schedule. Qualifying violations include tampering, driving a non-equipped vehicle, missed calibration, 3 missed rolling retests in 7 days, and canceled-driver violations (missing 30 monthly tests):

  • 1st violation occurrence: +180 days
  • 2nd violation occurrence: +1 year
  • 3rd+ violation occurrence: +545 days each
  • Positive test in final 90 days: +90 days added

The escalating penalties make later violations disproportionately costly — a third violation on a 2-year term adds nearly another 2 years. Keep a clean record throughout the full term.

Minnesota does not use SR-22 insurance. Instead, DVS requires a DVS Insurance Certification filed by your insurer — non-cancelable for up to 12 months — for revoked drivers. This is not the same as an SR-22. See our Minnesota insurance page → for what you actually need.

Minnesota DWI interlock FAQ

Is the interlock mandatory for a first DWI in Minnesota?
Not for a standard first offense (BAC under 0.16%) — you can choose to sit out the 90-day revocation with no driving instead. But if your BAC was 0.16% or higher, or you refused the test, the IID is the only way to drive at all during your 1-year revocation period. For second and subsequent offenses (within 20 years, incidents on/after 7/1/2025), participation is mandatory.
How long is the IID requirement in Minnesota?
First offense (under 0.16%): 90 days (180 days if under 21). First offense at 0.16%+ or refusal: 1 year. Second offense (within 20 years, on/after 7/1/2025): 2 years. Third offense: 6 years. Fourth or more: 10 years. Criminal Vehicular Homicide: 6 years up to lifetime for three or more convictions. Each violation occurrence adds 180 days, 1 year, or 545 days depending on how many you’ve had.
How did the July 1, 2025 law change affect Minnesota’s IID program?
For DWI incidents on or after July 1, 2025, Minnesota uses a 20-year lookback window to count prior offenses. A prior DWI from more than 20 years ago may not count toward your offense level for IID purposes. Pre-July 1, 2025 incidents may follow different rules. Confirm how this applies to your situation with your attorney or DVS.
Can I get a cost reduction in Minnesota?
Yes — the DVS Reduced Fee Program requires certified manufacturers to serve eligible participants at capped rates (e.g., $40 per service/calibration including device insurance per the 2026 certification). Qualifying programs include SNAP, Medical Assistance, MFIP, TANF, SSI, WIC, MinnesotaCare, General Assistance, Head Start, NSLP, EAP, CCAP, FDPIR, and MFAP. Provide a current acceptance letter to DVS and your provider before installation. Covers one vehicle; must reapply annually.
Which providers are certified in Minnesota?
Only three: Intoxalock, Smart Start, and LifeSafer. Guardian, Dräger/RoadGuard, and ALCOLOCK are not certified in Minnesota. Confirm current certification at dps.mn.gov before signing with any provider — using an uncertified provider does not satisfy your DVS requirement.
