The rules

What North Dakota requires

North Dakota leans on the 24/7 Sobriety Program rather than the interlock, but not from the first offense: a first DUI brings a 91-day suspension below 0.18% BAC and 180 days at or above it. From a second offense within seven years the state adds 360 days in the 24/7 program, where you report to a law enforcement location for testing, on top of a year or two of suspension.

  • First offense: A first offense carries a 91-day suspension below 0.18% BAC, or 180 days at 0.18% and above; the 360 days of 24/7 Sobriety Program participation start with a second offense within seven years
  • Lockout threshold: Set by the device where one is ordered; 24/7 testing is the more common condition
  • Program run by: North Dakota DOT and the Attorney General 24/7 Sobriety Program, through local law enforcement

What the charge itself carries in North Dakota: a first offence, a second and when it becomes a felony — the fine, the jail exposure and how long the licence stays restricted.

Why North Dakota asks for the device

Federal crash records are the backdrop to the rules on this page. Read the share with care though: it depends heavily on how often police obtain an alcohol test, and that varies enormously between states.

Finding a lawful installer

North Dakota points you at a phone number rather than a list

As in South Dakota, we found no certified-provider list published by a state agency. The directories that rank for the search are run by vendors, and one of them tells you to call the state DOT for the answer — which is, in fairness, the right advice.

  • North Dakota leans on the 24/7 Sobriety Program rather than the interlock, and not from the first offense: a first DUI brings a 91-day suspension below 0.18% BAC and 180 days at or above it.
  • The 360 days of 24/7 participation begin with a second offense within seven years, which is why interlock coverage in the state is thinner than the population alone would suggest.
  • The program is run by the DOT and the Attorney General through local law enforcement, so the agency supervising your case is the one to ask which device and provider it will accept.

Questions

Interlock questions in North Dakota

Is an ignition interlock mandatory in North Dakota?

North Dakota leans on the 24/7 Sobriety Program rather than the interlock, but not from the first offense: a first DUI brings a 91-day suspension below 0.18% BAC and 180 days at or above it. From a second offense within seven years the state adds 360 days in the 24/7 program, where you report to a law enforcement location for testing, on top of a year or two of suspension. As for how long: a first offense carries a 91-day suspension below 0.18% BAC, or 180 days at 0.18% and above; the 360 days of 24/7 Sobriety Program participation start with a second offense within seven years.

How much is an interlock device per month in North Dakota?

North Dakota 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.

What are the consequences of an interlock violation in North Dakota?

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 North Dakota DOT and the Attorney General 24/7 Sobriety Program, through local law enforcement 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.

How do I get the interlock restriction off my license in North Dakota?

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 North Dakota DOT and the Attorney General 24/7 Sobriety Program, through local law enforcement 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.

What blood alcohol level will fail an interlock in North Dakota?

North Dakota does not fix the number in the statute itself — it is set by the certifying agency in the device standard, and in practice sits between 0.02% and 0.025% BAC. Either way it is far below the 0.08% driving limit, which 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.

Is there an alternative to an ignition interlock device in North Dakota?

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.

Where can I get an ignition interlock device installed in North Dakota?

We index 9 certified installation points across 7 North Dakota cities, run by 3 approved providers, with the densest coverage in Minot, Williston, Bismarck. 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.
