A first DWI in Minnesota sets off two separate legal cases, costs the average driver somewhere between $7,000 and $12,000 once everything is tallied, and takes your license for 90 days to a full year depending on your test result. The legal blood alcohol limit is 0.08% for most drivers, 0.04% for commercial drivers, and any detectable alcohol for drivers under 21.1Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.20 – Driving While Impaired Even a clean first offense with no complications reaches well past the courtroom into your insurance, your job, and your ability to cross the border.
At the Arrest and Testing
If an officer has probable cause to believe you were driving impaired, you’ll be arrested and taken to a station for a breath, blood, or urine test. By driving on a Minnesota road, you’ve already consented to that test under the state’s implied consent law.2Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.51 – Chemical Tests for Intoxication Refusing doesn’t spare you a revocation; it makes the revocation longer.
Most people are released within a few hours of booking. The officer takes your physical license and hands you a temporary one. If your BAC reads 0.16% or higher, your license plates can be pulled off the vehicle on the spot and the car impounded.3Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.60 – Administrative Impoundment of Plates
Two Cases, Running at the Same Time
One arrest launches two independent proceedings, and winning one does not mean winning the other.
The criminal case goes through court and decides guilt, fines, jail, and probation. The administrative case is handled by the Minnesota Department of Public Safety and deals only with your license. The DPS revokes your driving privileges based on your test result or refusal, and that revocation stands even if the criminal charge is later reduced or dismissed.4Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.52 – Test Refusal or Failure; License Revocation
What a Standard First Offense Looks Like in Court
A first DWI with no aggravating factors is a fourth-degree DWI, which is a misdemeanor. The statutory maximums are 90 days in jail and a $1,000 fine.5Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.03 – Definitions Most first-time offenders don’t actually sit in jail. Judges typically stay the jail sentence, meaning you avoid it as long as you complete probation.
Probation usually runs a year or more. You’ll pay your fine, stay out of further trouble, and complete a chemical dependency assessment. The evaluator interviews you, reviews your driving record and the police report, and recommends a level of care, which can range from a short DWI education clinic to a longer treatment program.6Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.70 – Alcohol Safety Program; Chemical Use Assessments Ignoring the recommendation violates your probation.
Factors That Make a First Offense Worse
Three circumstances can bump a first DWI from a misdemeanor to a gross misdemeanor:
- A BAC of 0.16% or higher at the time of the offense or within two hours after.
- A passenger under 16 in the vehicle who is more than 36 months younger than you.
- A prior qualified impaired driving incident within the past ten years.
Any one of these elevates the charge to a third-degree DWI.5Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.03 – Definitions The maximum penalty climbs to one year in jail and a $3,000 fine.7Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.26 – Third-Degree Driving While Impaired If your BAC was 0.16% or higher, the court must order you to follow whatever treatment the assessment recommends, not merely consider it.
How Long You Lose Your License
The administrative revocation begins almost immediately and runs on its own clock:
- BAC between 0.08% and 0.15%: 90-day revocation.
- BAC of 0.16% or higher: one-year revocation.
- Test refusal: one-year revocation.
These periods come straight from the implied consent statute and apply regardless of what happens in the criminal case.4Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.52 – Test Refusal or Failure; License Revocation Because refusing doubles the revocation versus a standard failure, refusal rarely helps on a first offense.
Driving Again Before the Revocation Ends
You don’t necessarily have to park the car for the entire revocation. Minnesota’s Ignition Interlock Device Program lets eligible first-time offenders drive if they install a breath-testing device wired to the ignition.8Minnesota Department of Public Safety. Ignition Interlock Device Program You blow into the unit before the engine will start. Installation runs about $150, with roughly $95 per month in lease and monitoring fees for as long as you’re in the program.
When the revocation ends, full reinstatement costs $250 plus a $430 surcharge, for a total of $680.9Minnesota Office of the Revisor of Statutes. Minnesota Code 171.29 – Revoked License; Fee for Reinstatement A reduced-payment option exists for drivers who meet all other reinstatement conditions. You’ll also need proof that you’ve finished any treatment or counseling required of you.10Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.55 – Driver License Revocation; Reinstatement
Plate Impoundment and Whiskey Plates
Your plates get impounded if your BAC was 0.16% or higher, you had a child under 16 in the vehicle, or you have a prior impaired driving incident within the past ten years. This happens on a first arrest when any of those conditions is met.3Minnesota Office of the Revisor of Statutes. Minnesota Code 169A.60 – Administrative Impoundment of Plates
You can apply to the DPS for special registration plates, known locally as whiskey plates, that carry a distinct letter-and-number sequence recognizable to law enforcement. Regular plates can’t be reissued for at least one year from the impoundment date, and if you were the driver, you need a valid reinstated license first.
What a First DWI Actually Costs
The $1,000 statutory fine is only a small piece of the bill. A realistic breakdown looks like this:
- Court fine of up to $1,000, plus roughly $85 to $100 in surcharges.
- License reinstatement of $680, or about half under the reduced-payment plan.9Minnesota Office of the Revisor of Statutes. Minnesota Code 171.29 – Revoked License; Fee for Reinstatement
- Ignition interlock installation around $150, plus about $95 per month.
- Chemical dependency assessment, typically $100 to $200.
- Treatment or education programs, $300 to $1,000 depending on the recommendation.
- Probation supervision fees of $300 to $1,000 depending on the court.
- Attorney fees of $3,000 to $7,000 for a misdemeanor defense, higher in complicated cases.
- Insurance increases of 50% to 100% that commonly stay in place for five to seven years, adding $5,000 to $10,000 over that period.
Added together, most first-time offenders spend $7,000 to $12,000 before everything settles. The insurance surcharge alone often outweighs every other category combined.
Insurance After a First DWI
Minnesota doesn’t use the SR-22 filing common in other states. Instead, the DPS requires an insurance certification form before your license can be reinstated. If you don’t own a vehicle, you’ll file a non-owner’s or operator’s policy. Your insurer must notify the DPS if the policy lapses.
Insurers treat a DWI as a major risk factor, and premium hikes of 50% to 100% are routine. Those higher rates stick around. Most carriers keep the surcharge in place for five to seven years, which is why insurance ends up being the longest-lasting consequence of a first offense.
If You Hold a Commercial Driver’s License
A first DWI triggers a federal CDL penalty on top of the Minnesota consequences. Federal law requires a minimum one-year CDL disqualification for a first impaired-driving conviction, meaning you cannot operate any commercial vehicle during that period.11Office of the Law Revision Counsel. 49 USC 31310 – Disqualifications If you were hauling hazardous materials when the offense happened, the disqualification climbs to at least three years. It applies even if you were driving your personal car at the time of arrest.
How Long It Stays on Your Record
A misdemeanor DWI conviction stays on your Minnesota criminal record indefinitely. Fourth-degree DWI is specifically excluded from the state’s automatic expungement process.12Minnesota Office of the Revisor of Statutes. Minnesota Code 609A.015 – Automatic Expungement of Records Removing it requires petitioning the court for expungement, a separate proceeding with no guaranteed outcome.
The conviction will show up on background checks for years. Many employment screening services report criminal records going back seven years, and some jurisdictions allow indefinite reporting of convictions. Job applications that ask about criminal history will require disclosure for as long as the record stands.
Canada and Other International Travel
One consequence catches most first-time offenders off guard: the border. Canadian immigration law treats impaired driving as a serious criminal offense, and a single misdemeanor DWI can make you inadmissible.13Government of Canada. Overcome Criminal Convictions Border officers see U.S. criminal records and can turn you away at any crossing. For Minnesotans who drive to Canada for work, fishing, or long weekends, that’s an immediate problem.
Routes back exist, but none are fast. You can apply for criminal rehabilitation once at least five years have passed since you finished your entire sentence, including probation and license suspension. A temporary resident permit can cover urgent trips, granted at Canadian officials’ discretion. Mexico enforces its rules less consistently, but immigration authorities there also have legal power to deny entry over a criminal conviction, and the risk is higher when flying in because records are more likely to be checked.
