Maine Ignition Interlock Requirements (2026): Costs & Approved Providers
Maine’s interlock program is voluntary — there’s no all-offender mandate. The device is your ticket to early license restoration after serving 30 days of your OUI suspension. It’s the smart choice for anyone who needs to drive: it gets you back on the road months sooner, and low-income drivers pay 50% or less of provider fees by statute.
| Offense term | OUI (Operating Under the Influence) — Maine’s term for impaired driving |
| All-offender mandate? | No — voluntary early-restoration program under 29-A M.R.S. §2508 |
| 1st offense path | Serve 30 days of the 150-day suspension, then petition BMV for IID early restoration — drive for the remaining ~120 days with the device |
| 2nd offense path | Serve 9 months of the 3-year suspension, then IID for the remainder (approximately 2 years per BMV guidance) |
| 3rd offense path | Serve 3 years of the 6-year suspension, then IID for 3 additional years |
| 4th+ offense path | Serve 4 years of the 8-year suspension, then IID for 4 additional years |
| Violation consequence | IMMEDIATE re-suspension: 1 year (1st OUI), 2 years (2nd), 4 years (3rd), 6 years (4th+) |
| Driving without device / tampering | Class E crime: minimum 7 days jail + $500 fine |
| Low-income cost reduction | Certified installers must cut total fees by at least 50% for drivers with adjusted gross household income ≤ 150% FPL (29-A §2508) |
| BMV application fee | $50 |
| Who approves providers | Maine BMV — maine.gov IID information page |
| Governing law | 29-A M.R.S. §2508; §2411; §1603; 29-250 C.M.R. ch. 8 |
How Maine’s early restoration program works
Maine doesn’t require an interlock for all OUI offenders — it offers the device as the path to driving sooner. For a first offense, your license is suspended for 150 days. After serving 30 days with no driving, you can petition Maine BMV for an IID early restoration and drive for the remaining ~120 days with the device installed. The math is clear: 30 days of no driving + 120 days with a device vs. 150 days of no driving at all.
BMV must approve the installation before the device is installed — you cannot install first and seek approval after. The $50 application fee is paid to the Secretary of State at the time of your petition.
Maine BMV-listed providers
Three major providers appear on Maine’s certified list. Guardian, Dräger/RoadGuard, and ALCOLOCK are not on Maine’s approved provider list.
| Provider | Monthly est. | Coverage | |
|---|---|---|---|
| Intoxalock | $60–100 | Statewide | 888-283-5899 |
| Smart Start | $70–100 | Statewide | 800-831-3299 |
| LifeSafer | $65–95 | Statewide | 800-634-3077 |
Confirm current BMV certification on the Maine BMV IID page before signing. Guardian, Dräger/RoadGuard, and ALCOLOCK are not on Maine’s approved list. If your household income is ≤ 150% FPL, ask about the 50% statutory fee reduction before agreeing to any price.
What an interlock costs in Maine
| Installation (one time) | $70–150 (≥ 50% off if income ≤ 150% FPL) |
| Monthly lease + monitoring | $60–100 (≥ 50% off if income ≤ 150% FPL) |
| Removal | $50–75 (≥ 50% off if income ≤ 150% FPL) |
| BMV application fee | $50 |
Over a ~120-day first-offense IID period, expect roughly $400–650 in device costs before the $50 BMV fee (or half that with the income-based reduction). Estimate your exact cost →
How to get early restoration — 5 steps
- Serve the required initial hard suspension period: 30 days (1st offense), 9 months (2nd), 3 years (3rd), or 4 years (4th+).
- Petition Maine BMV for IID early restoration and pay the $50 application fee. BMV must approve before installation.
- Once approved, call a BMV-certified provider and schedule installation. If income-eligible, request the 50% statutory fee reduction at this step.
- Bring your vehicle and BMV approval to the installation appointment. Installation takes 60–90 minutes.
- Serve the full IID period with zero violations. Any violation triggers immediate re-suspension — there is no graduated warning system.
Violations — immediate re-suspension, no warnings
Maine has no graduated violation system. A single violation immediately re-suspends your license for a period based on your offense count — with no credit for time already served on the IID program:
- 1st OUI offense violation: Immediate 1-year re-suspension
- 2nd OUI offense violation: Immediate 2-year re-suspension
- 3rd OUI offense violation: Immediate 4-year re-suspension
- 4th+ OUI offense violation: Immediate 6-year re-suspension
Driving any vehicle without the device when required, or tampering with the device, is a Class E crime — minimum 7 days in jail and a $500 fine. Maine treats IID compliance as a serious matter. One mistake undoes all your progress and sets you back years.
