DWI / DUI
Minneapolis DWI Lawyer for Minnesota Drunk Driving Charges
A DWI arrest in Minnesota can create two immediate problems: a criminal case and potential consequences for your driving privileges. What happens next may depend on your alcohol concentration, prior impaired-driving history, whether there were aggravating factors, whether chemical testing was completed or refused, and the circumstances surrounding the traffic stop and arrest.
If you have been arrested for DWI or DUI in Minneapolis or elsewhere in Minnesota, it is important to understand that an arrest is not a conviction. The legality of the stop, the officer’s observations, field sobriety testing, chemical testing procedures, search warrants, and other evidence may all become important when evaluating the case.
Christopher Keyser, founder of Keyser Law, P.A., represents people facing Minnesota DWI charges ranging from a first-time Fourth Degree DWI to more serious repeat and felony DWI allegations. His practice focuses on criminal defense and includes both the criminal and practical consequences that can follow an impaired-driving arrest.
The earlier a DWI case is reviewed, the sooner potential defense issues can be identified, and important deadlines related to driving privileges or court proceedings can be addressed.

Understanding Minnesota DWI Laws and Chemical Testing
Minnesota law prohibits driving, operating, or being in physical control of a motor vehicle while impaired by alcohol, controlled substances, cannabis, certain intoxicating substances, or combinations of those substances. A person may also face a DWI charge based on an alcohol concentration of 0.08 or more measured within the time period established by Minnesota law.
For commercial motor vehicle drivers, different alcohol-concentration standards may apply. Minnesota also has separate rules affecting drivers under age 21.
Minnesota’s implied-consent laws also govern chemical testing after a DWI arrest. When a breath test is lawfully requested, the driver must be advised that Minnesota law requires the test, that refusing a breath test is a crime, and that the driver has a limited right to consult with an attorney before deciding whether to take the test.
Blood and urine testing are treated differently in important respects. Minnesota law provides for refusal offenses involving blood or urine testing when the test is required pursuant to a search warrant. Because chemical-test issues can affect both the criminal case and driving privileges, the circumstances surrounding the test request should be reviewed carefully.
Four Degrees of DWI Charges in Minnesota
Minnesota divides DWI offenses into four degrees. The level of the charge depends largely on prior impaired-driving incidents and aggravating factors.
Related impaired-driving charges can include DWI test refusal, careless driving, criminal vehicular operation, and criminal vehicular homicide.

Driver’s License and Administrative Consequences of a Minnesota DWI
A Minnesota DWI can involve administrative consequences in addition to the criminal prosecution. Depending on the circumstances, a driver may face license revocation, plate impoundment, vehicle forfeiture, ignition interlock requirements, or other restrictions that affect the ability to drive.
The length and type of license consequence can vary based on factors such as the test result, test refusal, prior impaired-driving incidents, the level of the offense, and whether other statutory conditions apply.
Drivers also have procedures available to seek administrative or judicial review of certain license revocations. Because these issues may operate independently of the criminal court case, it is important to evaluate both sides of a DWI matter rather than focusing solely on the criminal charge.
Other Consequences of a DWI Conviction
A DWI conviction can affect more than driving privileges. Depending on the case, consequences may include jail time, probation, fines, treatment or assessment requirements, an ignition interlock, increased insurance costs, employment concerns, professional licensing issues, commercial driving privileges, and a criminal record.
Repeat offenses and cases involving aggravating factors can expose a person to substantially greater consequences. A DWI involving an accident, injury, child passenger, high alcohol concentration, prior impaired-driving history, or other serious circumstances may require a different defense strategy than a typical first-time offense.
Building a Defense Against a Minnesota DWI Charge
A DWI case should be evaluated based on its individual facts. A test result does not automatically answer every legal question, and the defense is not limited to challenging a blood alcohol number.
A DWI lawyer may examine the reason for the traffic stop, whether there was probable cause for arrest, officer observations, body-camera and squad-car footage, field sobriety testing, chemical testing procedures, breath-testing records, blood or urine evidence, search warrants, witness testimony, and the driver’s prior record.
Depending on what the evidence shows, potential issues may involve whether the stop or seizure was lawful, whether testing procedures were followed correctly, whether chemical-test evidence is reliable and admissible, whether the state can establish that the defendant was driving or in physical control of the vehicle, or whether other weaknesses exist in the prosecution’s case.
At Keyser Law, P.A., the defense process begins by understanding what happened, reviewing the evidence, identifying the strongest legal and factual issues, and then determining whether the case should be negotiated, challenged through motions, or prepared for trial.
Free Initial Consultation
The first step is to contact Keyser Law, P.A. During your free initial consultation, we will listen to your side of the story, review the circumstances surrounding your arrest, and explain the strengths, risks, and legal issues involved in your case.

Reviewing the Evidence
If you hire Keyser Law, P.A., the next step is a detailed review of the evidence. We obtain and analyze the reports, video, test records, witness statements, and other materials the state may use against you. We keep you informed throughout the process and explain how the evidence may affect your defense strategy.
Executing Your DWI Defense Strategy
Once the evidence has been reviewed, we work with you to execute the defense strategy that best fits your case. Depending on the facts, that may involve challenging evidence, filing motions, negotiating with prosecutors, seeking reduced charges or penalties, or preparing for trial. The goal is to pursue the strongest available outcome while keeping you informed at every stage.
Crafting a DWI Defense Strategy
Every DWI case requires a strategy tailored to the facts, evidence, prior record, and your goals. We evaluate whether the best approach is to challenge the state’s evidence, negotiate for a favorable resolution, or prepare for trial. When appropriate, that may also include working with investigators, expert witnesses, or other professionals to strengthen the defense.
Common Issues a DWI Lawyer May Investigate
No single defense applies to every DWI case. The issues worth investigating depend on how the stop, arrest, and testing occurred. Questions may include:
- Did the officer have a lawful reason to stop the vehicle?
- Was there sufficient evidence to expand the traffic stop into a DWI investigation?
- Were field sobriety tests administered and interpreted appropriately?
- Was there probable cause for the arrest?
- Were the required chemical-test procedures followed?
- Was breath-testing equipment properly maintained and operated?
- Was blood or urine evidence obtained pursuant to lawful procedures?
- Is there an issue regarding who was actually driving or in physical control of the vehicle?
- Do video, witness testimony, or other evidence conflict with the police report?
- Do prior impaired-driving incidents actually qualify for enhancement of the current charge?
Identifying one of these issues does not guarantee that a DWI charge will be dismissed. It does, however, help determine whether evidence may be challenged, whether charges may be reduced, or whether the case should be prepared for trial.
Why Acting Quickly After a DWI Arrest Matters
A DWI case can begin affecting you before the criminal case is resolved. Driving privileges, vehicle or license-plate issues, release conditions, employment, commercial driving, and upcoming court dates can create immediate concerns.
Getting legal advice early gives your attorney an opportunity to preserve evidence, review video and test records, evaluate administrative consequences, identify deadlines, and begin developing a defense before important opportunities are lost.
If police have released you after a DWI arrest, that does not mean the matter is finished. A citation, summons, criminal complaint, license notice, or future court date may still require prompt attention.
Minneapolis DWI Defense for First-Time and Repeat Charges
Keyser Law, P.A. represents people facing both first-time and repeat DWI allegations. The strategy and potential consequences can change substantially depending on prior impaired-driving incidents and aggravating factors.
A first-time case may be charged as a Fourth Degree DWI when no aggravating factors are present. More serious cases may be charged as Third Degree DWI, Second Degree DWI, or First Degree DWI depending on the circumstances.
If you are unsure what degree of DWI you are facing, the complaint, citation, prior record, and alleged aggravating factors should be reviewed before drawing conclusions about the potential outcome.
