A Missouri DWI arrest starts two separate cases against you, and only one of them happens in a courtroom. The criminal case is the one people worry about. The administrative case — the Department of Revenue moving to suspend your driving privilege — is the one that runs on a 15-day fuse and is quietly lost by people who are waiting for their court date.
Two cases, one arrest
This is the single most misunderstood thing about a Missouri DWI, so it is worth being precise.
The criminal case is State of Missouri v. you, or a municipality against you. It is heard in circuit or municipal court, it moves at the pace of a court docket, and it decides whether you are convicted and what the sentence is.
The administrative case is the Department of Revenue acting against your driving privilege. It is not a criminal proceeding, it does not require a conviction, and it does not wait for the court. It begins the moment the officer issues you the Notice of Suspension — Form 2385, the piece of paper you were given at the station and may have assumed was a receipt.
The 15-day deadline, in the state’s own words
The Missouri Department of Revenue puts it this way: within 15 days from the date the Notice of Suspension or Revocation of Your Driving Privilege (Form 2385) is issued to you, a written request for a hearing must be received or postmarked. And then, without softening it: if you do not request a hearing within 15 days from the date the Form 2385 is issued to you, your hearing will be denied and no further appeal is possible.
Read that last part again. It is not a deadline that a good reason gets you past. There is no appeal from missing it.
Two details catch people out. The clock runs from the date the form was issued, not the date you found it or the date you sobered up. And the request must be received or postmarked inside the window — a request written on day 14 and posted on day 16 is late.
What actually happens, week by week
Day of arrest
If a breath test read at or above the limit, or you refused testing, the officer typically takes your Missouri licence and issues Form 2385, which usually serves as a temporary permit for a short period. You will also get a court date for the criminal side. These are two different pieces of paper about two different cases.
Days 1 to 15
This is the whole administrative window. The written hearing request has to be in. This is also when evidence is freshest and most recoverable: dashcam and bodycam footage that may be overwritten on a retention cycle, maintenance and calibration records for the breath instrument, the officer’s report, and witnesses who still remember the evening clearly.
If you do nothing else in this period, do this one thing.
Weeks 2 to 8
The criminal case begins to move — arraignment, discovery, disclosure of the state’s evidence. On the administrative side, the hearing gets scheduled if it was requested in time.
Months 2 onward
The two cases proceed on their own schedules and can end differently. It is entirely possible to win one and lose the other, because they are decided by different bodies applying different standards.
What refusing the test does
Missouri treats refusal as its own administrative matter with its own consequences, separate from whatever happens in the criminal case. People sometimes refuse in the belief that with no number there is no case. That is not how it works — refusal carries its own licence consequence, and the criminal case can still proceed on the officer’s observations, field sobriety testing and other evidence.
If you have already refused, that is not a reason to give up on the administrative side. It is a reason to move faster, because the same short window applies.
What defending a DWI actually looks like
Television has given people the impression that a DWI defence is a dramatic cross-examination. In practice it is far more often a technical, documentary exercise:
- The stop. The officer needed a lawful reason to pull you over in the first place. If that reason does not hold up, everything after it is in question.
- The testing. Breath instruments have maintenance schedules, calibration records and operator certification requirements. Those records either exist and are in order, or they do not.
- The field sobriety tests. These are standardised procedures with specific administration requirements. Administered incorrectly, their evidentiary value drops.
- The timeline. When the driving occurred relative to when the test was taken can matter a great deal.
None of that guarantees an outcome. It is simply where the actual work happens.
The prosecutor’s side of the table
Troy J. Leavitt spent part of his career as a prosecutor before moving to defence. On a DWI file that matters in an unglamorous way: he has been the person on the other side deciding what a case is worth, which files are strong, and which have a problem the report does not advertise. Knowing how the evaluation is made from the inside changes what you look for and what you argue.
Common questions
I already missed the 15 days. Is it over?
The administrative hearing is gone — the Department is explicit that there is no further appeal from that. The criminal case is not over, and it is still very much worth defending. Missing one deadline does not decide the other case.
Will I definitely lose my licence?
No. The administrative action is contestable, which is exactly what the hearing is for, and Missouri has limited driving privileges available in some circumstances. What is not survivable is doing nothing during the window.
Should I just plead guilty and get it over with?
That is a decision to make after you know what the evidence looks like, not before. A Missouri DWI conviction carries 8 points on your driving record on its own, which is the suspension threshold, and it is not something that quietly goes away later.
Does this apply to a municipal DWI?
The administrative action against your licence runs through the Department of Revenue regardless of which court the criminal case sits in. The 15-day window is the same.
What should I bring to a first meeting?
Form 2385, the citation or summons, any paperwork you were given at the station, and the date and time of arrest. If you have nothing, come anyway — the date is what matters most, because it tells us how much of the window is left.
