Fargo. Moorhead. Detroit Lakes. One DWI Defense Firm With Real Credentials.

Ringstrom DeKrey's MSBA-certified criminal law specialists defend DWI and DUI charges across the Red River Valley, with the board certification, experience, and track record to back it up.

North Dakota and Minnesota treat impaired driving seriously, but the two states use different terminology and carry different consequences.

In North Dakota, the charge is called Driving Under the Influence—a DUI. In Minnesota, it's called Driving While Impaired—a DWI. Different names, same core meaning: operating a vehicle while impaired by alcohol, drugs, or a combination of both.

The legal alcohol limit in both states is 0.08% blood alcohol concentration (“BAC”) for standard drivers. Commercial drivers are held to a stricter 0.04% BAC threshold. For drivers under 21, any detectable amount (meaning  0.01% BAC) of alcohol can trigger a charge.

In DWI/DUI cases, the most common test administered is a breath test. Law enforcement can also test your urine or blood. In the context of alcohol consumption, all three tests can calculate a person’s BAC. In the context of controlled substances, a urine or blood test can determine whether a controlled substance is present in a person’s body. Blood tests can also calculate the amount of a controlled substance present in a person’s body. 

Impairment doesn't require a breath, urine, or blood test. Officers can charge a driver based on driving conduct, observed behavior, observed physiological issues such as bloodshot or watery eyes, speech patterns, poor performance on field sobriety tests, and even a person’s attitude.

With many states legalizing marijuana, Law enforcement has started targeting THC impairment. This is a new frontier of DUI/DWI enforcement and primarily involves a different battery of field tests employed to detect drug impairment. While the techniques and tests used by officers in this context are different than traditional impaired driving tests, our attorneys are familiar with the standards and tests used in this context and prepared to attack the state’s case in this new area of enforcement.  

What triggers a DWI/DUI charge:

  • BAC at or above .08%

  • Visible impairment regardless of BAC
    Impairment from prescription medication

  • Presence of a controlled substance in the body

  • Refusal to submit to chemical testing (which carries its own penalties)

Because Ringstrom DeKrey practices on both sides of the Red River, their attorneys understand the distinct laws, court systems, and prosecution tendencies in both North Dakota and Minnesota, an advantage most local firms can't offer.

Credentials That Make a Difference in DWI Defense

DWI and DUI law is technical. Proving that you were not actually impaired, challenging a BAC test, contesting the validity of a traffic stop, and navigating administrative drivers license issues requires a level of specialization that goes beyond general criminal defense.

Ringstrom DeKrey's attorneys hold credentials that are rare in the region. Bruce Ringstrom Jr. and Dane DeKrey are two of only a handful of MSBA-certified Criminal Law Specialists in Minnesota and are the only ones practicing in the Red River Valley. That certification requires demonstrated courtroom experience, peer review, and a rigorous examination process. It isn't honorary.

Attorney Matt Keller also brings additional depth through his training with the National College for DUI Defense (NCDD), an organization dedicated exclusively to advancing the science and law of DUI defense. NCDD training covers everything from the pharmacology of alcohol to the mechanics of breath testing equipment, giving Matt the technical knowledge to challenge evidence that less-prepared defense attorneys might accept at face value. Matt has also completed the same Field Sobriety Testing and DWI Detection Training that police officers receive. In other words, Matt has the training to know when police do not conduct these tests properly and according to standard operating procedure. You can thus be confident that Ringstrom DeKrey will spot the nuances and mistakes officers make while in the field.

Finally, attorney Michael Minard has developed extensive DWI/DUI experience during his 13-year career as a criminal defense attorney. He has defended a large number of DUI/DWI cases, with many success stories. In 2024, he gave a presentation at a statewide criminal defense conference entitled "Challenging Field Sobriety Testing–a Workshop.” Not only has Michael defended hundreds of DUI/DWI charges, he also teaches other criminal defense attorneys how to be effective.

In total, the attorneys at Ringstrom DeKrey have defended over 450 DUI/DWI cases. They have the experience and expertise you need when facing a DUI/DWI charge.

When your case hinges on the legality of a traffic stop, an officer’s assertion that you are “impaired,” or the reliability of a breath test result, Ringstrom DeKrey’s depth of experience and training matters.
