North Dakota criminal-law insight
North Dakota First, Second, Third, and Fourth DUI Offenses: Penalties and Lookback Rules
North Dakota does not give every DUI the same sentence. Section 39-08-01 makes a first or second offense within seven years a class B misdemeanor, a third within seven years a class A misdemeanor, and a fourth or later within 15 years a class C felony. Subsection 5 then adds a distinct minimum package for each tier. The current charge, offense dates, certified prior convictions, and any first-offense alcohol concentration of at least .16 must be checked before a penalty estimate is useful.
How I use this analysis with a client
I use two columns with a client: criminal grading and sentence under § 39-08-01, then license suspension or revocation under chapter 39-20. In the first column, I verify the current DUI or actual-physical-control theory, the number of equivalent prior convictions, the lookback, and the mandatory subsection. In the second, I check test failure or refusal, the license history, and the permit issuance date. A “third DUI” label is not a substitute for either calculation.
The current incident still must be proved. Section 39-08-01 reaches driving or actual physical control on a place to which the public has a right of vehicular access, with a specified alcohol-concentration, influence, or covered refusal route. Video, timing, test records, advisory materials, and APC facts can affect that proof. A prior judgment may change the tier but cannot prove that the person committed the new offense.
Four parts of the analysis
First offense
Under § 39-08-01(3) and (5)(a), a first conviction is a class B misdemeanor with at least a $500 fine and an addiction evaluation. If the person’s alcohol concentration is at least .16, subsection (5)(a)(2) calls it an aggravated first offense and adds at least a $750 fine and two days of imprisonment. The .16 fact changes the minimum sentence; it does not itself turn the charge into a felony.
Second offense within seven years
A second offense within seven years remains a class B misdemeanor under § 39-08-01(3). Subsection (5)(b) requires at least ten days’ imprisonment, including 48 consecutive hours; a $1,500 fine; addiction evaluation; and at least 360 days in the 24/7 sobriety program as a mandatory probation condition. The statute contains specific rules for house arrest and credit, so “ten days” alone does not tell a person how the term may be served.
Third offense within seven years
A third offense within seven years is a class A misdemeanor. Section 39-08-01(5)(c) calls for at least 120 days’ imprisonment, at least a $2,000 fine, addiction evaluation, at least 360 days of supervised probation, and at least 360 days of 24/7 sobriety participation as a probation condition. Subsection (5)(f) limits suspension of the custody term, and subsection (6) regulates qualifying house arrest.
Fourth or later within fifteen years
A fourth or later qualifying offense within 15 years is a class C felony under § 39-08-01(3). Subsection (5)(d) calls for at least one year and one day of imprisonment, at least a $2,000 fine, addiction evaluation, at least two years of supervised probation, and 24/7 sobriety participation as a probation condition. Subsection (5)(f) limits suspension of the custodial portion. Verify whether each alleged prior falls in the 15-year window and qualifies as an equivalent offense.
North Dakota DUI/APC offense-tier comparison
This table separates the offense class from its DUI-specific minimum sentence. It does not calculate a person’s license period, predict a judge’s sentence, or treat a child-passenger or injury allegation as an ordinary DUI tier. Read every row with the current § 39-08-01 text and certified prior records; if the alleged incident predates a statutory change, use the law applicable to that incident.
| Stage or level | Governing issue | What requires close review |
|---|---|---|
| First offense | No qualifying prior in the applicable period | Class B misdemeanor; at least $500 fine and addiction evaluation |
| Aggravated first offense | First offense with alcohol concentration of at least 0.16 | Class B misdemeanor; at least $750 fine, at least two days’ imprisonment and evaluation |
| Second within seven years | One qualifying prior within seven years | Class B misdemeanor; at least ten days, $1,500 fine, evaluation and statutory sobriety-monitoring component |
| Third within seven years | Two qualifying priors within seven years | Class A misdemeanor; at least 120 days, at least $2,000 fine, evaluation, supervised probation and monitoring components |
| Fourth or later within fifteen years | Three or more qualifying priors within fifteen years | Class C felony; at least one year and one day, at least $2,000 fine, evaluation, supervised probation and monitoring provisions |
Build the prior-offense chart from certified records
A useful prior chart includes the earlier case number, court, state or ordinance, legal elements, offense commission date, conviction date, and certified disposition. Section 39-08-01(5)(g) counts a conviction under another state’s equivalent law when the offense was committed within the relevant time limit. This is not permission to count every arrest or every old administrative suspension as a criminal prior. Section 39-08-01.1 also excludes violations occurring before July 1, 1981, for purposes described there.
Mandatory components have execution rules
The minimum term is not a free-floating number. Section 39-08-01(5)(f) addresses which sentences may be suspended and allows a court to convert each day of an aggravated first-offense imprisonment term to ten hours of community service. Subsection (6) treats qualifying electronic house arrest as imprisonment for second and third offenses, subject to a 90-percent limit and 24/7 participation. Treatment credit and certain pretrial sobriety-program credit have separate rules in subsection (5)(h)–(j). The exact available route must be checked before promising “no jail” or a particular custody credit.
Passenger, injury, death and property statutes require separate pages
A § 39-08-01.4 DUI with a minor passenger has its own offense class, minimum sentence, and prior-offense rule. Section 39-08-01.2 separately defines criminal vehicular injury and homicide with their own felony classes and custody minimums. Section 39-08-01.3 permits vehicle forfeiture only when its ownership, current offense, prior-within-seven-years, and sentencing-order conditions are met. None is automatically included in the ordinary first-through-fourth DUI table.
How North Dakota counts DUI offenses and applies mandatory terms
Start by separating four layers: the present § 39-08-01 violation, the criminal class assigned by subsection 3, the subsection 5 minimum sentence, and the chapter 39-20 licensing action. A first or second offense may share a class B ceiling while having sharply different minimum custody and probation conditions. A driver can also face a license consequence on the administrative track before a criminal conviction.
A first offense is not consequence-free
A non-aggravated first offense does not have the same two-day minimum as a first offense with an admissible concentration of at least .16. Both require addiction evaluation and a fine under § 39-08-01(5)(a), but the minimum fine changes from $500 to $750 when the aggravated-first rule applies. A test value should be checked against the statutory concentration definition, timing, and foundational records before it is used to set that minimum.
A second offense uses a seven-year window
For a second offense, the prior must fit the seven-year rule and equivalent-offense language. Section 39-08-01(5)(b) requires ten days, including 48 consecutive hours, a $1,500 fine, evaluation, and 360 days of 24/7 sobriety participation as a probation condition. Subsection (6) permits defined house arrest to count as imprisonment but not for more than 90 percent of the term. That is materially different from treating all ten days as discretionary probation.
A third offense within seven years is a higher criminal class
A third within seven years becomes class A misdemeanor under § 39-08-01(3), with the 120-day, $2,000, evaluation, supervised-probation, and 24/7 terms in subsection (5)(c). Under subsection (5)(f), the district court may suspend part of a qualifying sentence but not 60 days of imprisonment, subject to the stated treatment-evaluation condition. This is one reason to check the actual statutory subsection before describing a proposed plea.
A fourth or later offense uses a longer lookback and felony treatment
A fourth or later within 15 years is the felony tier, not simply “another repeat misdemeanor.” Section 39-08-01(5)(d) sets a one-year-and-one-day custody minimum and at least two years of supervised probation, plus fine, evaluation, and sobriety-program conditions. Under subsection (5)(f), one year of imprisonment is generally protected from suspension under that provision. The class C maximum comes from § 12.1-32-01; the felony classification may also affect employment and professional reporting separately.
Concentration can alter minimum consequences
The .16 threshold belongs to the aggravated-first criminal minimum in § 39-08-01(5)(a)(2). It is not the same as the .18 threshold used for certain test-failure license-suspension periods in § 39-20-04.1. A person with .17 may face the aggravated-first minimum yet fall below that .18 administrative tier. Test timing, method, and actual record matter for both calculations.
Actual physical control uses the same tier structure but different facts
The historical tier can apply to APC, but the current-incident evidence may focus on a stationary vehicle, keys, operability, position, location, and purpose rather than observed driving.
Refusal and chemical testing follow chapter 39-20 procedures
A covered refusal is a criminal alternative under § 39-08-01(1)(a)(5)–(6), with constitutional-consistency advisory language, and it may separately trigger revocation under chapter 39-20. The refusal does not automatically create a new prior conviction or erase the need to prove the current violation. The officer’s grounds, test request, advisory, conduct treated as refusal, and administrative notice should be reviewed separately.
Child passenger, injury, or death allegations require separate mapping
Do not add a child-passenger or injury sentence to the ordinary table without the additional charged and proved elements. Section 39-08-01.4 requires an adult driver at least 21 and a minor accompanying the driver, with a separate class A or repeat class C structure. Section 39-08-01.2 requires that a DUI violation cause death or substantial or serious bodily injury and sets distinct felony and minimum-custody rules. These consequences deserve their own analysis.
Class maximums are not the whole sentence
General class ceilings in § 12.1-32-01 are 30 days and $1,500 for class B misdemeanor, 360 days and $3,000 for class A misdemeanor, and five years and $10,000 for class C felony. Section 39-08-01(5) supplies the DUI minimum package inside those ceilings. Neither a ceiling nor a minimum alone predicts the full judgment; the court order, statutory custody limits, treatment provisions, and applicable probation terms must be read together.
A tier worksheet prevents counting errors
Use one sheet for prior convictions and another for the present event. In the first, identify jurisdiction, offense conduct date, statute or ordinance, certified disposition, and comparability. In the second, identify driving or APC evidence, charged alcohol or drug route, test or refusal details, any at-least-.16 first-offense result, and any separate passenger or injury count. This keeps a concentration enhancement from being miscounted as a conviction and prevents a license loss from being silently substituted for a criminal prior.
North Dakota DUI offense tiers
| Issue | What controls | Why it matters |
|---|---|---|
| First offense | Current § 39-08-01 and no qualifying prior in the relevant period | Misdemeanor tier with statutory mandatory components. |
| Second within seven years | One qualifying prior | Enhanced minimums and supervision requirements. |
| Third within seven years | Two qualifying priors | Class A misdemeanor tier with increased mandatory exposure. |
| Fourth or later within fifteen years | At least three qualifying priors | Felony treatment and a felony sentencing analysis. |
North Dakota DUI offense-level questions
Does a first DUI require jail?
Not for a non-aggravated first offense under the minimum in § 39-08-01(5)(a)(1): it requires at least a $500 fine and addiction evaluation. If the first-offense alcohol concentration is at least .16, subsection (5)(a)(2) requires at least two days’ imprisonment and a $750 fine, subject to the statute’s specific community-service conversion rule. A court can still impose a lawful sentence above a minimum.
How far back does North Dakota count priors?
Section 39-08-01(3) uses seven years for the second and third criminal tiers and 15 years for a fourth or later tier. Section 39-08-01(5)(g) looks to when an equivalent out-of-state offense was committed. Confirm the actual dates and version of law, rather than using the number of years since a case closed.
Does an APC count like a DUI?
Yes. Section 39-08-01 includes actual physical control. A stationary-car case may turn on vehicle location, operability, keys, occupant position, and other circumstances, but the same criminal tier provisions apply when the violation is proved. The current APC allegation and prior convictions are separate proof questions.
Can an out-of-state DUI count?
Yes, if the earlier conviction was for an equivalent law or ordinance and its offense was committed within the applicable limit under § 39-08-01(5)(g). Compare the certified judgment and earlier law. An out-of-state arrest, citation, or administrative entry without the required conviction should not be counted as one automatically.
Does a refusal change the offense count?
A refusal is a separate § 39-08-01 criminal route and may create a chapter 39-20 license case; it does not by itself change the number of qualifying prior convictions. The state still must prove the statutory refusal prerequisites and the current violation. The criminal sentence then depends on the properly established tier.
Are jail minimums the same as license revocation periods?
No. Sections 39-08-01(3) and (5) govern criminal classes and minimum terms. Chapter 39-20 uses separate test-failure or refusal rules and prior driving-history criteria. For instance, § 39-20-04.1 distinguishes certain .08-to-below-.18 results from results at or above .18. The permit and notice, not the criminal tier alone, identify the administrative action.
Can priors be challenged?
Yes. Review the certified judgment, offense date, jurisdiction, equivalence, and any claimed constitutional defect through applicable procedures. A prior summary is not conclusive just because it appears on a driving record. The time and validity of each prior can determine whether the present case is class B, class A, or class C.
Is the statutory maximum the likely sentence?
No. Section 12.1-32-01 states an outer class ceiling. Section 39-08-01(5) supplies mandatory DUI terms, while the court resolves a case within the lawful framework and any valid agreement. An actual sentence also depends on the proved tier, custody and probation rules, and separate license consequences; the statutory maximum is not a forecast.

Need an explanation tied to the actual charge?
Bring the present complaint and every certified prior judgment to a private consultation, along with the temporary operator’s permit and test or refusal paperwork. The useful question is not simply “What number DUI is this?” It is which convictions qualify under which window, what clause the state can prove now, which minimum follows, and whether the license-hearing deadline is still open.
How to use this information in a real North Dakota repeat-offense DUI/APC
Read the charging document as an element map
Copy the charged § 39-08-01 clause into an element chart. Driving or actual physical control in a place covered by the statute must be connected to the particular alcohol, drug, combination, concentration, or refusal alternative. Then list the convictions alleged to produce the second, third, or fourth tier, with a certified source for each. A prior changes grading; it does not cure a failure of proof on the present incident.
Create a source-based record, not a memory-based story
Request source documents rather than relying on a criminal-history label. Keep the present complaint, test and video records, temporary permit, and release order. For every prior, keep the judgment, charging statute or ordinance, plea or verdict, and conduct and disposition dates. An out-of-state entry needs enough source law to assess equivalence under § 39-08-01(5)(g). Mark an incomplete record “unverified,” not “counted.”
Build one chronology before evaluating credibility
Put the alleged present driving/APC time beside test time and refusal request, then place each prior offense commission date on the seven- or 15-year chart. The administrative license history belongs on a different line because chapter 39-20 can count driving-history events under its own rules. The ten-day § 39-20-05 hearing period is measured from temporary-permit issuance, not from the prior offense or first criminal hearing.
Separate admissibility from persuasive weight
Evidence has distinct jobs in a tier case. Video and witnesses can address whether the present driving or APC occurred; chemical-test records can address a numerical clause or .16 first-offense minimum; the advisory and response can address refusal; certified judgments can address priors. A document that proves one proposition does not prove the others. Compare admissibility, authenticity, and weight before making a plea or trial forecast.
Measure the prosecution’s proof one element at a time
At trial the prosecution must prove the current § 39-08-01 violation beyond a reasonable doubt. The factual and procedural treatment of prior convictions or additional offenses depends on the charging and applicable law; counsel should identify the proper record and decision-maker for each. An element chart should distinguish current vehicle control and impairment or refusal from the historical convictions used for tiering. A .16 first-offense sentence fact is not the same as a new prior.
Calendar every independent deadline and condition
Calendar the criminal hearings and the independent Department process. Under § 39-20-05 the hearing request ordinarily must be made within ten days after temporary-permit issuance; § 39-20-06 provides a separate short judicial appeal after a hearing. Add any bond testing or 24/7 obligation shown in the written order. Document submission and compliance, because a missed administrative date is not repaired by later discussing a criminal plea.
Preserve evidence without creating a new problem
Preserve original video, location data, receipts, messages, test records, and vehicle information for the present incident. Obtain certified copies—not altered screenshots—of prior judgments. If the earlier case was in another state, retain its statute or ordinance as it existed at the time. Avoid contact that violates an order or pressures a witness. These records allow counsel to test both the present elements and the claimed tier.
Distinguish statutory maximums, mandatory terms, and likely outcomes
Read the class ceiling and mandatory minimum together. A second DUI is still class B, with a general 30-day/$1,500 ceiling, but § 39-08-01(5)(b) requires ten days and a $1,500 fine plus evaluation and sobriety-program conditions. A third is class A with a 360-day/$3,000 ceiling and a 120-day/$2,000 minimum package. A fourth is class C with a five-year/$10,000 ceiling and a one-year-and-one-day/$2,000 minimum package. Statutory suspension, house-arrest, and treatment-credit provisions can affect execution and must be evaluated separately.
Account for consequences outside the courtroom
Do not merge criminal sentencing with the license decision. Chapter 39-20 can suspend after a qualifying test or revoke after a refusal; duration varies by result and driving record, including .18 test-failure distinctions. Commercial-vehicle privileges, insurance, professional reporting, restricted driving, and treatment may have different triggers. A criminal dismissal, amendment, or sentence does not automatically vacate an administrative action.
Evaluate negotiations against the trial record
A plea proposal should specify the current offense clause, the number and identity of qualifying priors, and whether an at-least-.16 first-offense fact remains. Then calculate § 39-08-01(5)’s custody, fine, evaluation, probation, and 24/7 terms and review any lawful sentence-execution provision. Ask what happens to separately charged § 39-08-01.4 passenger or § 39-08-01.2 injury counts. The existing chapter 39-20 order needs its own resolution.
Prepare for trial by narrowing the real disputes
Trial preparation should not collapse the present offense and historical tier into one accusation. The current case may turn on contact basis, APC circumstances, testing foundation, or refusal advisory. Each prior should be supported by a certified, comparable conviction and the relevant commission date. Cross-examination and motions should target a genuine issue in one of those components. The defendant does not have to prove innocence of the new charge.
Use current primary law and an offense-date check
Verify the version of § 39-08-01 in effect on the alleged offense date and compare any out-of-state prior with its source law. Sections 39-08-01(3), (5), and (6), § 39-08-01.1, § 12.1-32-01, and chapter 39-20 govern different parts of the analysis. Do not cite a modern penalty table as if it necessarily governed an older incident. The official legislative PDFs linked below provide current text; historical text may require separate research.
Questions this North Dakota repeat-offense DUI/APC guide should help answer
What exactly has been charged?
Write the current count, § 39-08-01 subsection, alleged offense date, and whether driving or APC is asserted. Write the state’s alleged prior count separately, with each certified case number. Note a .16 result only if the aggravated-first minimum is at issue. A child-passenger, injury, or homicide count needs its own statutory row; the booking shorthand “fourth DUI” is not enough to explain a multi-count case.
Which facts can change the offense level?
Test each prior against the applicable lookback and equivalence rule. A second or third criminal tier uses seven years; the fourth-or-later felony tier uses 15 years. Section 39-08-01(5)(g) addresses an equivalent out-of-state conviction committed within those limits, while § 39-08-01.1 excludes pre-July 1981 offenses for the specified chapters. Do not treat a single test result, refusal, or administrative suspension as if it were another conviction without a statutory basis.
What should be brought to the first substantive review?
Bring the complaint, all prior judgments or case identifiers, the full temporary permit and report and notice, test or refusal paperwork, release order, and any available video or receipts. A short timeline of where the vehicle and keys were is especially useful for APC. Tell counsel about work driving and any existing license restriction, but confirm lawful status before driving. The first review should settle deadlines and tier proof before discussing a likely offer.
Which dates and orders control conduct right now?
Separate the § 39-20-05 hearing-request period, criminal court dates, release testing, and any later judicial-review deadline under § 39-20-06. Keep filing and delivery confirmations. If 24/7 participation is ordered during pretrial release, document it; § 39-08-01(5)(j) allows a sentencing court to consider certain compliant pretrial participation for credit against a later probation condition. Do not assume credit is automatic or that missing a program date is harmless.
How should a proposed outcome be compared?
Compare any outcome against the correctly proved tier, the applicable subsection 5 minimum, the class maximum, and the independent license period. For a second case, the 48-consecutive-hour requirement is material; for a third, the 60-day nonsuspendable portion under the specified rule matters; for a fourth, the one-year nonsuspendable portion under that rule matters. Ask which terms the court can lawfully alter, what treatment or house-arrest credit is available, and what a probation violation would change. This concrete comparison is more useful than a generic “first through fourth DUI” chart.
