A first DUI in North Dakota: what it can result in
Verified · next review
A fine and an addiction evaluation — no jail unless the reading was 0.16. North Dakota keeps the first and the second offence in the same class — a class B misdemeanor, which carries a maximum of thirty days and $1,500 — and puts the difference in the mandatory sentence rather than the grading. An ordinary first offence must carry a fine of at least $500 and an order for addiction evaluation by a licensed treatment programme, and nothing else. At an alcohol concentration of sixteen one-hundredths or more the statute calls it an aggravated first offence: the fine floor rises to $750 and at least two days’ imprisonment becomes mandatory. The court may not suspend a first or second offence sentence at all, though for the aggravated first it may convert each day of imprisonment into ten hours of community service. Deferring imposition of sentence under the general provision at § 12.1-32-02(4) is expressly unavailable for any offence under this section. Refusing the chemical test is itself an offence under the same section, so a refusal does not sidestep the tier.
Written any number of ways — a 1st offense DUI, DUI 1st, DUI first offense ND, or a first DUI in ND — and the paperwork will use none of them. North Dakota charges it under a section number, and that is what decides the range below.
Grade. Class B misdemeanor
Confinement. None on an ordinary first offence; not less than 2 days at 0.16 or above
Fine. At least $500; at least $750 on an aggravated first offence

What turns this DUI into something worse
Each line below is a separate provision with its own punishment range. They stack with the arithmetic of prior convictions rather than replacing it.
| The fact | What it makes it | Detail and source |
|---|---|---|
| An alcohol concentration of 0.16 or more on a first offence | Aggravated first offence — at least two days and a $750 fine | The class does not change, but the sentence acquires a custody floor an ordinary first offence does not have. It is the only tier where the court may convert each day of imprisonment into ten hours of community service.

The device is a separate track
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.
In North Dakota the interlock term runs 91 days and is administered by North Dakota DOT and the Attorney General 24/7 Sobriety Program, through local law enforcement — which is why a plea that settles the criminal case does not settle the device. What counts as a violation on it, and what an agency adds to the term, is its own arithmetic: violations and lockouts. Getting it off at the end is a procedure of its own too — removal and waivers.

North Dakota DUI questions
Is jail time mandatory for a 1st DUI in North Dakota?
North Dakota keeps the first and the second offence in the same class — a class B misdemeanor, which carries a maximum of thirty days and $1,500 — and puts the difference in the mandatory sentence rather than the grading. An ordinary first offence must carry a fine of at least $500 and an order for addiction evaluation by a licensed treatment programme, and nothing else. At an alcohol concentration of sixteen one-hundredths or more the statute calls it an aggravated first offence: the fine floor rises to $750 and at least two days’ imprisonment becomes mandatory. The court may not suspend a first or second offence sentence at all, though for the aggravated first it may convert each day of imprisonment into ten hours of community service. Deferring imposition of sentence under the general provision at § 12.1-32-02(4) is expressly unavailable for any offence under this section. Refusing the chemical test is itself an offence under the same section, so a refusal does not sidestep the tier.
How likely is jail time for a first DUI in ND?
Start from what the statute forces and what it leaves to the judge. The floor here is none on an ordinary first offence; not less than 2 days at 0.16 or above, and it moves on the facts: an alcohol concentration of 0.16 or more on a first offence means aggravated first offence — at least two days and a $750 fine. Everything above that floor is argued, and the same conviction can end up served in custody, on work release or as a condition of probation depending on the county and the judge. What no one can promise you is a sentence below the statutory minimum — that is not a question of persuasion.
What is the punishment range for a 1st DUI in North Dakota?
Class B misdemeanor: none on an ordinary first offence; not less than 2 days at 0.16 or above, and a fine of at least $500; at least $750 on an aggravated first offence. The range is set by N.D.C.C. § 39-08-01(3), (5)(a), (5)(e), (5)(f); § 12.1-32-01(6), and the figures on this page come from the statute rather than from a summary of it.
What makes it worse in North Dakota?
An alcohol concentration of 0.16 or more on a first offence — aggravated first offence — at least two days and a $750 fine.
Does an interlock come with it 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. The device requirement and the criminal penalty are separate tracks: one is handled by the court, the other by North Dakota DOT and the Attorney General 24/7 Sobriety Program, through local law enforcement.
