A single DWI arrest in Minnesota opens two separate files. One is the criminal case, handled by a prosecutor in district court. The other is a license matter, driven by the Department of Public Safety, which can revoke driving privileges on its own timeline whether or not the criminal case ever ends in a conviction. The two tracks share the same facts but follow different rules, and a result in one does not automatically settle the other.
Each term marks a point where an officer made a decision or a statute set a requirement. Defense review works by checking those points one at a time, because a problem at an early step can affect what happens later on both tracks.
Drivers who want an experienced advocate for White Bear Lake dwi defense can turn to attorney Charles Gerlach, whose practice centers on DWI and DUI defense alongside a broader criminal defense caseload. He spent more than two decades as a prosecutor before moving to the defense side, and that background shapes how he reads both the criminal file and the license record, though every case turns on its own facts.

1. Reasonable Suspicion
Reasonable suspicion: the legal standard an officer must meet to pull a vehicle over. It requires specific facts pointing to a possible violation, such as a traffic infraction or erratic driving, rather than a general hunch.
A defense attorney compares the reason written in the report with what the squad video actually shows. Timing matters too, including how long the driver was followed and whether the cited behavior appears on camera. If the stop lacked a lawful basis, the evidence gathered afterward can be challenged, which is why this is usually the first question asked.
2. Field Sobriety Tests
Standardized field sobriety tests: a set of three roadside tests developed through federal highway safety research, namely horizontal gaze nystagmus, the walk and turn, and the one leg stand. Each has set instructions and scoring criteria. A handheld preliminary breath test at the roadside is a separate screening tool, not the evidentiary test used later.
An attorney checks whether the officer gave the instructions as trained and scored the clues correctly. Conditions count as well: road surface, lighting, weather, footwear, and any physical condition that could affect balance. These tests often support the decision to arrest, so how they were run can shape the strength of everything that follows.
3. Implied Consent
Implied consent: the principle that driving in Minnesota carries consent to chemical testing under conditions set by law. Under Minnesota Statutes section 169A.51, an officer reads a breath test advisory before requesting a breath sample, and two deficient breath samples are treated as a refusal.
Defense review here focuses on the advisory itself: whether it was read accurately, whether the driver understood it, and whether there was a reasonable opportunity to contact an attorney before deciding on the test. A refusal and a test failure are handled differently on both tracks, so the exact sequence of events at the station gets close attention.
4. Breath, Blood or Urine Testing
Evidentiary test: the chemical test the state relies on in court. Breath tests are run on an approved instrument, usually at a station. Under the same statute, a blood or urine test may be taken only with a search warrant or a recognized exception to the warrant requirement.
For breath results, an attorney looks at the instrument’s maintenance and certification records, the operator’s training and the observation period before the sample. For blood or urine, the review moves to the warrant application, the chain of custody and the lab’s methods. The number on a report is only as reliable as the process that produced it.
5. Administrative License Revocation
Administrative license revocation: a civil action by the state against driving privileges, triggered by a test failure or refusal and separate from any criminal charge. Minnesota Statutes section 169A.53 allows a driver to petition the district court for judicial review within 60 days of receiving the notice and order of revocation, and filing that petition does not pause the revocation. A written administrative review by the commissioner is also available during the revocation period.
An attorney tracks the date the notice was received, weighs whether to seek judicial review, and looks at whether ignition interlock eligibility offers a lawful way to keep driving. The license hearing can also give an early look at officer testimony, which may inform the criminal side of the case.
6. First Appearance and Arraignment
Arraignment: the opening court date in the criminal case, where the charge is formally presented, rights are explained and release conditions are set. Depending on the facts and any prior history, a DWI may be charged at different levels, and the complaint states which level the prosecutor has chosen.
At this stage, an attorney reviews the complaint for the specific statutory sections cited and checks any release conditions, such as alcohol restrictions or monitoring, for whether they fit the client’s work and family obligations. This is also where the criminal schedule and the license timeline are lined up, so a decision on one track does not create an unexpected result on the other.
Taken together, these six terms show why a DWI is rarely a single question of whether someone was over a limit. The stop, the roadside tests, the advisory, the chemical result, the license action and the court charge each follow their own rules and leave their own records. Reviewing them in order gives a driver a clearer picture of where the case stands on both tracks before any decision has to be made.
