Ignition Interlock Device Minnesota: Program Rules, Cost, and Eligibility

What Is Minnesota's Ignition Interlock Program?

Minnesota's Ignition Interlock Device Program (IIDP) lets DWI offenders restore full driving privileges immediately — no waiting period, no hourly restrictions, no geographic limits. The device integrates into your vehicle's starter system and prevents the engine from turning over if it detects a breath alcohol concentration of 0.02 or higher.

Unlike the limited license (work permit), which restricts you to 60 hours per week of driving for specific purposes, the interlock program allows unlimited driving in any vehicle equipped with the device. For anyone whose BAC tested at 0.16 or higher, interlock is the only path back behind the wheel — the limited license option is completely unavailable at that threshold.

Who Is Eligible

The interlock program is available to all first-time offenders regardless of BAC level or whether they refused testing. It is also available to repeat offenders. The key eligibility requirements:

• Must be at least 18 years old (underage drivers are statutorily ineligible)
• Must have valid vehicle liability insurance (Form PS35016 or equivalent)
• Must sign the IID Participation Agreement (Form PS31202)
• Must pay the $680 DVS reinstatement fee (can be paid in installments under HF 2130 — but full payment is required before transitioning to an unrestricted license)

One critical detail: signing the Participation Agreement waives your right to challenge the administrative revocation. If you're considering filing an Implied Consent petition, don't enroll in interlock until you've made that decision — the two paths are mutually exclusive.

What It Costs

Interlock is not cheap, and the costs stack up over the program duration:

Over a 90-day program (standard first offense with BAC under 0.16), total interlock costs run roughly $300–$570 on top of the $680 reinstatement fee. For a one-year program (high BAC or refusal), expect $930–$1,830 in device-related costs alone.

The Reduced-Fee Program

If your household income falls below 150% of the Federal Poverty Guidelines, you can apply for Minnesota's reduced-fee interlock program. Submit a notarized "Reduced Fee for Ignition Interlock Service and Monitoring" form to DVS, and your monthly lease and calibration costs drop by 50%.

DVS also allows the $680 reinstatement fee to be paid through its partial-pay program: $395 up front ($365 plus a $30 filing fee), with the remaining $345 ($315 plus $30) due within two years.

How Rolling Retests Work

Starting the car requires a clean breath sample. But the testing doesn't stop there. The device requires "rolling retests" at random intervals while you drive:

• First retest: 5–7 minutes after starting the engine
• Subsequent retests: every 15–45 minutes
• You get a 10-minute window to provide a passing sample after the alert

A failed retest, a missed retest, or a BAC reading of 0.02 or higher gets logged as a violation. Under DVS rules, every sample is presumed to be yours — if a family member or mechanic triggers a failure while using your vehicle, that violation still appears on your record.

Common triggers for false readings include alcohol-based mouthwash and certain fermented foods. Rinse thoroughly with water and wait several minutes before any test to avoid a localized mouth-alcohol lockout.

Calibration and Monitoring Appointments

You must bring the vehicle to an approved service center every 30–60 days. During these appointments, the technician downloads the device's logged data, recalibrates the sensors, and physically inspects the unit. Missing a calibration appointment is treated as a program violation.

Under the 2025 legislative reforms (HF 2130), completing a licensed substance use disorder treatment program is now a mandatory prerequisite for full license reinstatement. DVS can hold your license in restricted interlock status indefinitely until your treatment provider submits certified completion documentation.

Certified Manufacturers in Minnesota

Five manufacturers are currently certified by DVS to provide interlock devices in Minnesota: Intoxalock, Smart Start, LifeSafer, RoadGuard Interlock, and LowCost Interlock. The full list with contact information is available on the DVS website. Costs and service center locations vary — get quotes from at least two vendors before committing.

Interlock vs. Limited License: Which Makes Sense?

Choose interlock if you need unrestricted driving (no hourly caps, no destination limits), if your BAC was 0.16 or above (you have no other option), or if you want to bypass whiskey plates by paying a $100 early-reinstatement fee per vehicle.

Choose a limited license if your BAC was under 0.16, you can manage within the 60-hour-per-week restriction, and you want to avoid monthly device costs.

Both paths require the $680 reinstatement fee. The limited license has a mandatory 15-day hard wait; interlock has none.
