North Dakota DUI laws set a blood alcohol concentration limit of 0.08% for standard drivers, 0.04% for commercial drivers, and 0.02% for drivers under 21. A first offense is a Class B misdemeanor with a fine starting at $500. A fourth or subsequent offense within 15 years becomes a Class C felony with a minimum fine of $2000. This guide covers penalty tiers, license suspension, and implied consent under the North Dakota Century Code and the North Dakota Department of Transportation.
Key Terms Defined
North Dakota law uses the term actual physical control instead of only driving. This means a person can face DUI charges while seated in a vehicle with access to the keys even if the engine is off and the vehicle never moves. Courts look at the person’s location in the vehicle and their ability to operate it rather than requiring proof that the vehicle was actually driven on a road.
Implied consent means a driver has already agreed to chemical testing simply by driving on North Dakota roads. If a law enforcement officer has reason to believe a driver is impaired, the driver is legally bound to submit to a breath, blood, or urine test. Refusing a required chemical test is treated as its own violation under North Dakota law and can trigger separate administrative and criminal consequences apart from any DUI charge.
North Dakota uses a lookback period to decide whether a new DUI counts as a repeat offense. A first, second, or third offense is measured against a 7 year lookback window. A fourth or subsequent offense uses a longer 15 year lookback window. This dual system means an older conviction outside the shorter window may not count toward a second or third offense but could still count toward a fourth offense calculation.
What the Law Says
Under North Dakota Century Code Section 39-08-01, a person may not drive or be in actual physical control of a vehicle on a highway or on public or private areas the public has a right to access for vehicular use while impaired. The statute applies if the driver’s alcohol concentration reaches 0.08% or higher, if the driver is under the influence of intoxicating liquor, or if the driver is under the influence of drugs or a combination of drugs and alcohol to a degree that makes safe driving impossible.
The BAC threshold changes depending on the type of driver. Standard drivers are held to the 0.08% limit. Commercial drivers operating under a commercial license face a stricter 0.04% limit. Drivers under the age of 21 are subject to a zero tolerance standard, meaning any detectable alcohol concentration of 0.02% or higher can support a DUI charge, regardless of visible impairment.
North Dakota law also treats a chemical test refusal as its own basis for a DUI charge. A person who refuses a required blood, breath, or urine test after being properly advised of the consequences can be found guilty under Section 39-08-01 even without a measured BAC result. This applies separately from the administrative license suspension that follows a refusal.
Who It Applies To
North Dakota DUI law applies to any person operating or in actual physical control of a vehicle on a public highway or on private or public areas the public may access for vehicular use. This includes standard passenger vehicle drivers, commercial vehicle operators, and drivers of multipassenger bicycles, though a passenger on a multipassenger bicycle cannot be charged under this statute. The law applies statewide and does not vary by county or municipality within North Dakota.
Penalties by Offense
A first offense DUI in North Dakota is a Class B misdemeanor. The sentence must include a fine of at least $500 and a court ordered addiction evaluation through a licensed treatment program. If the driver’s BAC measured 0.16% or higher, the offense becomes an aggravated first offense, raising the mandatory minimum fine to $750 and adding at least two days of imprisonment, according to North Dakota Century Code Section 39-08-01.
A second offense within the 7 year lookback period remains a Class B misdemeanor but carries harsher mandatory terms. The sentence must include at least 10 days of imprisonment, with at least 48 hours served consecutively, along with a fine of $1500. The court must also order an addiction evaluation and require at least 360 days of participation in the 24 7 sobriety program as a mandatory condition of probation.
A third offense within 7 years is charged as a Class A misdemeanor. The mandatory sentence includes at least 120 days of imprisonment, a fine of at least $2000, an addiction evaluation, and at least 360 days of supervised probation. The offender must also complete at least 360 days in the 24 7 sobriety program. Some of this jail time may be suspended if the person completes a court approved treatment program.
A fourth or subsequent offense within a 15 year lookback period is a Class C felony. The mandatory minimum sentence includes at least one year and one day of imprisonment and a fine of at least $2000, with a maximum fine of $10000. The court must also impose at least two years of supervised probation and require participation in the 24 7 sobriety program as a mandatory condition of that probation.
Administrative License Suspension vs Criminal Penalties
North Dakota separates DUI consequences into two distinct tracks. The North Dakota Department of Transportation handles administrative license suspension, while the criminal court system handles fines, jail time, and probation. A driver can face both processes at the same time following a single DUI arrest, and completing one process does not automatically resolve the other.
According to the NDDOT penalties for driving under the influence page, a first offense results in a 91 day license suspension if BAC was below 0.18%, or a 180 day suspension if BAC reached 0.18% or higher. A second offense within 7 years results in a 365 day suspension below 0.18% BAC, rising to a two year suspension at 0.18% or above. A third offense carries a two year suspension below 0.18% BAC and a three year suspension at 0.18% or higher.
Criminal court penalties are separate from these administrative suspension periods and are handled entirely by the judge in the criminal case. The court decides jail time, probation length, and fine amounts based on the mandatory minimums set by Section 39-08-01 and the specific facts of the case, including BAC level and prior offense history within the applicable lookback period.
Enhanced and Special Penalties
An aggravated first offense applies when a first time offender registers a BAC of 0.16% or higher. This designation adds a mandatory fine increase to $750 and at least two days of imprisonment on top of the standard first offense penalties, even though the offense remains a Class B misdemeanor rather than being reclassified to a higher offense level.
DUI with a minor passenger carries its own enhanced penalty structure under North Dakota Century Code Section 39-08-01.4. If a person age 21 or older violates the DUI statute while a minor is in the vehicle, the offense becomes a Class A misdemeanor for a first violation. A second or subsequent violation of this specific provision becomes a Class C felony, regardless of how many general DUI offenses the person has accumulated.
Chemical test refusal triggers penalties separate from a standard DUI conviction. According to NDDOT, refusing a required chemical test may result in license revocation ranging from 180 days to three years, depending on the driver’s prior refusal or conviction history. Refusal can also be prosecuted as a criminal offense in its own right under Section 39-08-01, independent of any BAC based charge.
Criminal vehicular injury and criminal vehicular homicide apply when a DUI results in serious harm to another person. Under North Dakota Century Code Section 39-08-01.2, causing serious bodily injury while violating the DUI statute is a Class B felony with a mandatory minimum of one year and one day of imprisonment. Causing a death is a Class A felony with a mandatory minimum of three years, rising to 10 years for a prior DUI conviction.
The 24 7 Sobriety Program
The 24 7 Sobriety Program is a court supervised alcohol monitoring program used across North Dakota since January 2008. Participation can be ordered as a condition of bond, pretrial release, sentencing, or probation for a second or subsequent DUI, and it may also be used voluntarily by a driver seeking a temporary restricted license through the North Dakota Department of Transportation.
Program participants must submit to twice daily breath testing or wear continuous alcohol monitoring equipment, and they are financially responsible for all associated testing fees under the North Dakota Attorney General 24 7 Sobriety Program guidelines. Fees include $1 per breath test, a $6 daily monitoring fee for bracelet devices, and additional charges for drug patch or urinalysis testing when ordered by the court.
Exceptions and Limitations
North Dakota allows a limited form of sentence reduction through treatment court participation. Under Section 39-08-01.5, all but 10 days of the mandatory minimum sentence for a third or subsequent DUI may be suspended if the defendant successfully completes a treatment court, mental health court, or veterans treatment docket program approved by the state supreme court. A felony conviction resolved this way may be treated as a misdemeanor upon successful program completion.
Record sealing is available in limited circumstances under Section 39-08-01.6. A person convicted of a single DUI offense may have that record sealed if they have not been convicted of a subsequent DUI or any other criminal offense within 7 years of the first violation. This sealing provision does not apply to individuals licensed as commercial drivers, and sealed records remain accessible to prosecutors for enhancement purposes in future DUI cases.
Common Misconceptions
Many people assume a DUI requires the vehicle to be moving, but North Dakota law applies to actual physical control, meaning a person can be charged while parked with keys accessible. Another common misconception is that refusing a chemical test avoids penalties entirely. In reality, refusal triggers its own administrative license suspension and can be prosecuted as a separate criminal violation under the same DUI statute.
Some readers also assume that a fourth DUI automatically counts once four total convictions exist. North Dakota actually requires those prior convictions to fall within the applicable lookback period, using seven years for a second or third offense calculation and fifteen years for a fourth or subsequent offense calculation. An older conviction outside the fifteen year window would not count toward a felony level charge.
Laws and enforcement practices may change over time, and North Dakota has added provisions in recent years covering treatment court sentence reductions and limited record sealing. Readers should check official state sources for the most current version of these rules before relying on any specific penalty figure, especially given how frequently DUI statutes are amended by the state legislature.
