Ignition interlock devices in Minnesota

Minnesota runs the interlock as a program you enroll in, not just a device you fit. It is the route back to driving during a revocation, and it is mandatory for repeat offenses. The device is defined by statute as one that blocks the ignition at 0.02% or above. As for how long: optional for a first offense; mandatory on a second or later alcohol or drug offense within 20 years (10 years for incidents before 1 July 2025). Drivers canceled as inimical to public safety serve 3–6 years.

Minnesota does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. A quote far above that is the provider's, not the state's.

A recorded event is not automatically a violation, and that distinction decides most cases. Programs differ in what they count and how they count it: some add time per event, others ignore single events and act on a pattern, and several give you a written escape where a retest within five or ten minutes comes back clean. What is uniform is that the decision is made by Minnesota Department of Public Safety, Driver and Vehicle Services from the vendor's report, not at the roadside. The mechanics, state by state and with the statute on each, are on our page about violations and lockouts.

Not at the workshop, and not on the date in your paperwork. The state releases you first and the device comes out last: you finish the term including anything added to it, sit a final data download at the service center, let Minnesota Department of Public Safety, Driver and Vehicle Services review the record, take what it issues to a licensing office to lift the restriction, and only then book the removal. Most programs also require a clean window before any of that starts — 180 days in Washington, the last 30 in New Jersey, three months in Maryland.

0.02% — the statute defines the device as one that blocks the ignition at that reading or above That is far below any driving limit, and it is why one drink shortly before a test is enough to fail it: the device is testing whether you drank, not whether you are impaired.

Sometimes, and it is usually stricter rather than easier. The common substitute is continuous alcohol monitoring — a transdermal ankle bracelet that watches the person instead of the car, all day rather than at the ignition. North Carolina writes the trade directly into sentencing: 120 days of monitored abstinence can cut a 30-day minimum to ten, and 90 days can replace a seven-day term. The other alternative is not driving at all, which some states allow you to serve out instead, and which costs you the license for the whole period rather than the device.

We index 305 certified installation points across 184 Minnesota cities, run by 6 approved providers, with the densest coverage in Saint Paul, Duluth, Minneapolis. Install with a provider the state approves rather than the nearest pin on the map: time on an unapproved device does not count toward the term.
