How Long Will I Have to Spend in Jail for a DWI in Minnesota?
Being charged with a DWI (Driving While Impaired) in Minnesota can feel overwhelming, especially when you’re worried about potential jail time. The good news is that not every DWI results in incarceration: outcomes depend on factors like your blood alcohol concentration (BAC), prior offenses, and aggravating circumstances.

Understanding DWI Penalties in Minnesota
Minnesota classifies DWI offenses into four degrees, with penalties escalating based on the number of prior offenses and aggravating factors. Jail time is not always mandatory, especially for first-time offenders, but it becomes more likely with repeats or high BAC levels.
Importantly, Minnesota’s “look-back period” for prior impaired driving incidents was extended from 10 to 20 years in May 2025, meaning older convictions could now enhance current charges and increase penalties. This change primarily affects license revocations and enhancements but underscores the importance of challenging charges early.
Here’s a breakdown of typical jail penalties by DWI degree. Keep in mind these are maximums—skilled representation can often reduce or eliminate jail through negotiations, evidence challenges, or alternative sentencing like community service or house arrest.
| DWI Degree | Typical Scenario | Maximum Jail Time | Fines | Other Notes |
|---|---|---|---|---|
| Fourth-Degree (Misdemeanor) | First-time offense, no aggravating factors, BAC under 0.16% | Up to 90 days | Up to $1,000 | Often no jail for low-BAC first-timers; may include community service instead. License revocation: 90 days (limited license after 15 days). |
| Third-Degree (Gross Misdemeanor) | DWI with one aggravating factor (e.g., BAC 0.16%+, test refusal, or one prior within 20 years) | Up to 1 year | Up to $3,000 | Mandatory minimums may apply for priors; e.g., 30 days total (48 hours in custody, rest on house arrest) if one prior. License revocation: 1 year (with ignition interlock possible). |
| Second-Degree (Gross Misdemeanor) | DWI with two or more aggravating factors (e.g., two priors, child in vehicle) | Up to 1 year | Up to $3,000 | Higher likelihood of jail; e.g., 90 days minimum (30 days in custody, 60 on house arrest) for two priors. License revocation: 1-2 years, plate impoundment. |
| First-Degree (Felony) | Fourth or subsequent DWI within 20 years, or with serious aggravating factors | Up to 7 years (possible prison) | Up to $14,000 | Mandatory minimums often include 180 days (30 in custody) for third prior, or more for four+; vehicle forfeiture possible. License cancellation: 4-10 years, with ignition interlock for reinstatement. |
These penalties can also include administrative consequences like immediate license revocation under implied consent laws, even before a conviction. Refusing a chemical test (breath, blood, or urine) can lead to automatic 1-year revocation and enhanced charges.
Aggravating Factors That Can Increase Jail Time
Even for a first-time DWI, certain elements can bump up the degree and raise the risk of jail:
- High BAC: 0.16% or above often requires ignition interlock for 1 year and increases fines/jail likelihood.
- Test Refusal: Treated as an aggravating factor, leading to longer revocations and potential additional charges.
- Child in Vehicle: If under 16, it counts as an aggravator, potentially adding plate impoundment.
- Prior Offenses: With the new 20-year look-back, convictions from up to two decades ago can elevate your charge.
- Accidents or Injury: Property damage, injuries, or reckless behavior (e.g., speeding) can lead to harsher sentencing.
- Underage Drivers: Minors face zero-tolerance (any alcohol), with multi-faceted impacts on licenses and records.
Drug-related DWIs (e.g., cannabis or THC) follow the same penalty structure—no specific BAC limit, but impairment evidence can result in arrest and equivalent consequences.
Do First-Time Offenders Always Go to Jail?
Not necessarily. For a standard first-time DWI with BAC under 0.16% and no aggravators, jail is often avoided. You might face fines, a short license suspension, and education programs instead.
However, if your BAC is 0.20% or higher, cooperation issues arise, or an accident is involved, the chance of some jail time increases. Courts consider your overall record, behavior during the stop, and any probation status.

169A.275 MANDATORY PENALTIES; NONFELONY VIOLATIONS.
Plain-English snapshot: This section covers second, third, fourth, and fifth‑or‑more DWI offenses charged as non‑felonies. It sets minimum jail or community service requirements, explains when a court can depart from the minimums, and outlines options like home detention, intensive probation, and staggered sentencing. Key point: even when some jail can be converted to alternatives, a short in‑custody component is often mandatory.
Subdivision 1.Second offense.
(a) The court shall sentence a person who is convicted of a violation of section 169A.20 (driving while impaired) within ten years of a qualified prior impaired driving incident to either:
(1) a minimum of 30 days of incarceration, at least 48 hours of which must be served in a local correctional facility; or
(2) eight hours of community work service for each day less than 30 days that the person is ordered to serve in a local correctional facility.
Notwithstanding section 609.135 (stay of imposition or execution of sentence), the penalties in this paragraph must be executed, unless the court departs from the mandatory minimum sentence under paragraph (b) or (c).
(b) Prior to sentencing, the prosecutor may file a motion to have a defendant described in paragraph (a) sentenced without regard to the mandatory minimum sentence established by that paragraph. The motion must be accompanied by a statement on the record of the reasons for it. When presented with the prosecutor’s motion and if it finds that substantial mitigating factors exist, the court shall sentence the defendant without regard to the mandatory minimum sentence established by paragraph (a).
(c) The court may, on its own motion, sentence a defendant described in paragraph (a) without regard to the mandatory minimum sentence established by that paragraph if it finds that substantial mitigating factors exist and if its sentencing departure is accompanied by a statement on the record of the reasons for it. The court also may sentence the defendant without regard to the mandatory minimum sentence established by paragraph (a) if the defendant is sentenced to probation and ordered to participate in a program established under section 169A.74 (pilot programs of intensive probation for repeat DWI offenders).
(d) When any portion of the sentence required by paragraph (a) is not executed, the court should impose a sentence that is proportional to the extent of the offender’s prior criminal and moving traffic violation record. Any sentence required under paragraph (a) must include a mandatory sentence that is not subject to suspension or a stay of imposition or execution, and that includes incarceration for not less than 48 hours or at least 80 hours of community work service.
Subd. 2.Third offense.
(a) The court shall sentence a person who is convicted of a violation of section 169A.20 (driving while impaired) within ten years of the first of two qualified prior impaired driving incidents to either:
(1) a minimum of 90 days of incarceration, at least 30 days of which must be served consecutively in a local correctional facility; or
(2) a program of intensive supervision of the type described in section 169A.74 (pilot programs of intensive probation for repeat DWI offenders) that requires the person to consecutively serve at least six days in a local correctional facility.
(b) The court may order that the person serve not more than 60 days of the minimum penalty under paragraph (a), clause (1), on home detention or in an intensive probation program described in section 169A.74.
(c) Notwithstanding section 609.135, the penalties in this subdivision must be imposed and executed.
Subd. 3.Fourth offense.
(a) Unless the court commits the person to the custody of the commissioner of corrections as provided in section 169A.276 (mandatory penalties; felony violations), the court shall sentence a person who is convicted of a violation of section 169A.20 (driving while impaired) within ten years of the first of three qualified prior impaired driving incidents to either:
(1) a minimum of 180 days of incarceration, at least 30 days of which must be served consecutively in a local correctional facility;
(2) a program of intensive supervision of the type described in section 169A.74 (pilot programs of intensive probation for repeat DWI offenders) that requires the person to consecutively serve at least six days in a local correctional facility; or
(3) a program of staggered sentencing involving a minimum of 180 days of incarceration, at least 30 days of which must be served consecutively in a local correctional facility.
(b) The court may order that the person serve not more than 150 days of the minimum penalty under paragraph (a), clause (1), on home detention or in an intensive probation program described in section 169A.74. Notwithstanding section 609.135, the penalties in this subdivision must be imposed and executed.
Subd. 4.Fifth offense or more.
(a) Unless the court commits the person to the custody of the commissioner of corrections as provided in section 169A.276 (mandatory penalties; felony violations), the court shall sentence a person who is convicted of a violation of section 169A.20 (driving while impaired) within ten years of the first of four or more qualified prior impaired driving incidents to either:
(1) a minimum of one year of incarceration, at least 60 days of which must be served consecutively in a local correctional facility;
(2) a program of intensive supervision of the type described in section 169A.74 (pilot programs of intensive probation for repeat DWI offenders) that requires the person to consecutively serve at least six days in a local correctional facility; or
(3) a program of staggered sentencing involving a minimum of one year of incarceration, at least 60 days of which must be served consecutively in a local correctional facility.
(b) The court may order that the person serve the remainder of the minimum penalty under paragraph (a), clause (1), on intensive probation using an electronic monitoring system or, if such a system is unavailable, on home detention. Notwithstanding section 609.135, the penalties in this subdivision must be imposed and executed.
Subd. 5.Level of care recommended in chemical use assessment.
Unless the court commits the person to the custody of the commissioner of corrections as provided in section 169A.276 (mandatory penalties; felony violations), in addition to other penalties required under this section, the court shall order a person to submit to the level of care recommended in the chemical use assessment conducted under section 169A.70 (alcohol safety program; chemical use assessments) if the person is convicted of violating section 169A.20 (driving while impaired) while having an alcohol concentration of 0.16 or more as measured at the time, or within two hours of the time, of the offense or if the violation occurs within ten years of one or more qualified prior impaired driving incidents.
Subd. 6.Definitions.
(a) For purposes of this section, the following terms have the meanings given.
(b) “Staggered sentencing” means a sentencing procedure in which the court sentences a person convicted of a gross misdemeanor or felony violation of section 169A.20 (driving while impaired) to an executed sentence of incarceration in a local correctional facility, to be served in equal segments in three or more consecutive years. Before reporting for any subsequent segment of incarceration after the first segment, the offender shall be regularly involved in a structured sobriety group and may bring a motion before the court requesting to have that segment of incarceration stayed. The motion must be brought before the same judge who initially pronounced the sentence. Before bringing the motion, the offender shall participate for 30 days in a remote electronic alcohol-monitoring program under the direction of the person’s probation agent. It is within the court’s discretion to stay the second or subsequent segment of remote electronic alcohol monitoring or incarceration that has previously been ordered. The court shall consider any alcohol-monitoring results and the recommendation of the probation agent, together with any other factors deemed relevant by the court, in deciding whether to modify the sentence by ordering a stay of the next following segment of remote electronic alcohol monitoring or incarceration that the court had initially ordered to be executed.
(c) When the court stays a segment of incarceration that it has previously ordered to be executed, that portion of the sentence must be added to the total number of days the defendant is subject to serving in custody if the person subsequently violates any of the conditions of that stay of execution.
(d) A structured sobriety group is an organization that has regular meetings focusing on sobriety and includes, but is not limited to, Alcoholics Anonymous.
Subd. 7.Exception.
A judge is not required to sentence a person as provided in subdivisions 1 to 4 if the judge requires the person as a condition of probation to drive only motor vehicles equipped with an ignition interlock device meeting the standards described in section 171.306
169A.276 MANDATORY PENALTIES; FELONY VIOLATIONS.
Plain-English snapshot: This is Minnesota’s felony‑level DWI sentencing rule. It requires a prison sentence (not less than three years) for first‑degree DWI, with limited room for a stayed execution and a lengthy conditional‑release period after prison. Translation: if you’re facing a felony DWI, the stakes are higher, timelines are longer, and early strategic defense is critical.
Subdivision 1.Mandatory prison sentence.
(a) The court shall sentence a person who is convicted of a violation of section 169A.20 (driving while impaired) under the circumstances described in section 169A.24 (first-degree driving while impaired) to imprisonment for not less than three years. In addition, the court may order the person to pay a fine of not more than $14,000.
(b) The court may stay execution of this mandatory sentence as provided in subdivision 2 (stay of mandatory sentence), but may not stay imposition or adjudication of the sentence or impose a sentence that has a duration of less than three years.
(c) An offender committed to the custody of the commissioner of corrections under this subdivision is not eligible for release as provided in section 241.26, 244.065, 244.
(d) Notwithstanding the statutory maximum sentence provided in section 169A.24 (first-degree driving while impaired), when the court commits a person to the custody of the commissioner of corrections under this subdivision, it shall provide that after the person has been released from prison the commissioner shall place the person on conditional release for five years. The commissioner shall impose any conditions of release that the commissioner deems appropriate including, but not limited to, successful completion of an intensive probation program as described in section 169A.74 (pilot programs of intensive probation for repeat DWI offenders). If the person fails to comply with any condition of release, the commissioner may revoke the person’s conditional release and order the person to serve all or part of the remaining portion of the conditional release term in prison. The commissioner may not dismiss the person from supervision before the conditional release term expires. Except as otherwise provided in this section, conditional release is governed by provisions relating to supervised release. The failure of a court to direct the commissioner of corrections to place the person on conditional release, as required in this paragraph, does not affect the applicability of the conditional release provisions to the person.
(e) The commissioner shall require persons placed on supervised or conditional release under this subdivision to pay as much of the costs of the supervision as possible. The commissioner shall develop appropriate standards for this.
Subd. 2.Stay of mandatory sentence.
The provisions of sections 169A.275 (mandatory penalties; nonfelony violations), subdivision 3 or 4, and subdivision 5, and 169A.283 (stay of execution of sentence), apply if the court stays execution of the sentence under subdivision 1 (mandatory prison sentence). In addition, the provisions of section 169A.277 (long-term monitoring) may apply.
Subd. 3.Driver’s license revocation; no stay permitted.
The court may not stay the execution of the driver’s license revocation provisions of section 169A.54 (impaired driving convictions and adjudications; administrative penalties).
169A.74 PROGRAMS OF INTENSIVE PROBATION.
Plain-English snapshot: This section describes county‑run intensive probation programs for repeat DWI offenders. Think structured supervision: treatment, testing, work requirements, home detention, and graduated steps. Courts may use these programs to manage risk and, in some cases, reduce time actually spent in custody if you comply.
Subdivision 1.Grant application.
The commissioners of corrections and public safety, in cooperation with the commissioner of human services, shall jointly administer a program to provide grants to counties to establish and operate programs of intensive probation for repeat violators of the driving while impaired laws. The commissioners shall adopt an application form on which a county or a group of counties may apply for a grant to establish and operate an impaired driving repeat offender program.
Subd. 2.Goals.
The goals of the impaired driving repeat offender program are to protect public safety and provide an appropriate sentencing alternative for persons convicted of repeat violations of section 169A.20 (driving while impaired), who are considered to be of high risk to the community.
Subd. 3.Program elements.
To be considered for a grant under this section, a county program must contain the following elements:
(1) an initial assessment of the offender’s chemical dependency, based on the results of a chemical use assessment conducted under section 169A.70, with recommended treatment and aftercare, and a requirement that the offender follow the recommended treatment and aftercare;
(2) several stages of probation supervision, including:
(i) a period of incarceration in a local or regional detention facility;
(ii) a period during which an offender is, at all times, either working, on home detention, being supervised at a program facility, or traveling between two of these locations;
(iii) a period of home detention; and
(iv) a period of gradually decreasing involvement with the program;
(3) decreasing levels of intensity and contact with probation officials based on the offender’s successful participation in the program and compliance with its rules;
(4) a provision for increasing the severity of the program’s requirements when an offender offends again or violates the program’s rules;
(5) a provision for offenders to continue or seek employment during their period of intensive probation;
(6) a requirement that offenders abstain from alcohol and controlled substances during the probation period and be tested for such use on a routine basis; and
(7) a requirement that all or a substantial part of the costs of the program be paid by the offenders.
Subd. 4.Training.
Counties participating in the program shall provide relevant training in intensive probation programs to affected officials.
