A DWI arrest in Missouri starts two clocks at once: a criminal case filed by the county prosecutor, and a separate license process run by the Missouri Department of Revenue. The license deadline is short — shorter than most people realize — and missing it forfeits the only chance to contest the license action, independent of how the criminal case turns out.
This page is general orientation, not legal advice. If you’ve been arrested for DWI, the right call is to a defense lawyer.
The first 24-72 hours
After the arrest, you’re typically booked at the county detention facility, given a court date, and released on bond. Around the same time, the Missouri Department of Revenue issues a notice that starts the administrative-license process. The notice has a deadline on it for requesting a hearing — that’s the deadline that matters most in the first week.
Two cases, not one
The criminal case is what most people think of as “the DWI.” It’s filed by the Jackson, Clay, Platte, or Cass County Prosecuting Attorney, depending on where the arrest happened, and it’s where the fine, jail (if any), probation, and conviction record live.
The administrative-license case is separate, decided by a hearing officer at the Department of Revenue, not the criminal court. It’s about whether you keep your license while the criminal case plays out. Two different decision-makers, two different deadlines, two different standards.
What a defense lawyer does in week one
The lawyer’s first job is preserving options. That usually means:
- Requesting the administrative-license hearing inside the deadline
- Pulling the police report, body-camera, and any chemical-test records
- Identifying any problem with the stop, the field-sobriety procedure, or the chemical-test calibration
- Walking you through what’s actually likely to happen in your specific county
Most defense lawyers offer a free consultation. Given how short the license-side deadline is, the first call should happen in days, not weeks.
What this page doesn’t tell you
The specific number of days you have to request the hearing, the actual penalty range for your charge, whether you qualify for a restricted license, and whether your specific facts give you a defense — these are all questions for a defense lawyer who can look at your case. This site is informational and doesn’t give legal advice or create an attorney-client relationship.

Common questions
How fast do I need to act?
Faster than most people think. The license-side deadline runs from the arrest, not from your first court date. A defense lawyer can move on it the same day.
Will I lose my license?
A Missouri DWI arrest typically starts a separate process against your license, with its own short deadline to contest it. Whether you keep driving — and on what conditions — depends largely on how that process is handled in the first few days.
Do I need a lawyer if I'm planning to plead?
Most people benefit from at least a consultation before deciding. A defense lawyer can tell you whether there's a defense worth fighting, what diversion or treatment options exist in your county, and what the actual plea offer means in real terms.
