Arrested for DWI in Missouri? The 15-Day License Clock Is Already Running.
A Missouri DWI hits you on two tracks at once — the criminal charge in court, and a separate license action run by the Missouri Department of Revenue that almost nobody warns you about. The officer took your plastic license and handed you a 15-day temporary permit, and that 15-day countdown starts from your arrest date, not your court date. Let it lapse and the suspension takes effect on its own, with no hearing and no appeal. Before the clock runs out, call 1-844-690-0555 free, 24/7. You'll get clear legal information about both tracks — not legal advice, just clarity, in plain English.

DWI Defense in Missouri — what to do right now
Do one thing today: find the paper the officer gave you (the 'Notice of Suspension/Revocation') and look at your arrest date. You have 15 days from that date to request an administrative hearing from the Missouri Department of Revenue in writing — or your suspension takes effect on the 16th day, completely separate from anything that happens in criminal court. Don't wait for a court date in the mail; that's the wrong clock. Call 1-844-690-0555 now, free and 24/7, and we'll walk you through exactly how the hearing request works and what your deadline is.
The law in Missouri: DWI Defense
Missouri splits drunk driving into two distinct criminal charges from a single arrest. RSMo § 577.010 is 'Driving While Intoxicated' (DWI) — operating a vehicle in an intoxicated condition, which an officer can build from your driving, your speech, field sobriety tests, and the breath result together. RSMo § 577.012 is the separate 'per se' charge of Driving With Excessive Blood Alcohol Content — operating at 0.08% or higher, regardless of how impaired you seemed. You can be charged under both from one stop, and prosecutors routinely plead one while dismissing the other. Missouri also runs three BAC thresholds: 0.08% for adult drivers, 0.04% for commercial drivers, and 0.02% zero-tolerance for drivers under 21.The second track is administrative and it moves faster than the courts. Under RSMo § 302.505, the Department of Revenue suspends or revokes your license based purely on the arrest and the test result — a process that runs whether or not you're ever convicted of anything. Sections 302.520 and 302.530 govern the 15-day temporary permit and the hearing you must request to fight it. If you tested over the limit, this is a 90-day suspension on a first alcohol contact; if you refused the test under § 577.041's implied-consent law, it's a one-year revocation with no limited driving privilege for the first 90 days at all.
Where your criminal case is heard depends on how it's charged. A first offense filed as a city ordinance violation goes to Municipal Court (judge only, no jury). A state-charged misdemeanor first or second offense goes to the Associate Circuit Court. Felony DWIs — Persistent Offender and up — go to the Circuit Court, which is also where you file a petition for review of a refusal revocation in the county of arrest. Missouri's offender ladder under §§ 577.001 and 577.023 is unusually granular: prior, persistent, aggravated, chronic, and habitual labels each escalate the penalty. A second offense within five years makes you a Prior Offender (still a misdemeanor); two or more prior alcohol contacts — at least one within ten years — make you a Persistent Offender, the point where Missouri DWI crosses into felony territory.
Legal Hotline is not a law firm and not a public defender, and a call creates no attorney-client relationship — we give legal information, not legal advice. But because Missouri's two clocks run on different timetables, knowing which deadline is yours, and which court or agency it belongs to, is the single most valuable thing you can do in the first 48 hours. Call 1-844-690-0555 and an AI assistant trained on Missouri and federal law will map both tracks for you for free.

Two Clocks, and the One That Blindsides You Runs From Your Arrest Date
Here's the trap almost every Missouri DWI arrest springs. You walk out focused on your future court date — but a second, faster clock is already ticking, and it has nothing to do with the criminal case. Under Missouri's administrative system, you have just 15 days from the date of your arrest to demand a hearing from the Department of Revenue, in writing. Miss it and your suspension takes effect on the 16th day with no hearing — even if your criminal charge later gets reduced or thrown out entirely. Most states run this clock from the date the notice is served; Missouri runs it from arrest, so it can expire while you're still waiting for a court letter that never mentions it. Don't let the wrong clock cost you your license. Call 1-844-690-0555 free, 24/7.

Real Missouri DWI exposure depends on your BAC, your prior alcohol contacts, and whether you refused testing. These are the statutory ranges — not a prediction of your case.Mistakes to avoid

FAQ — DWI Defense in Missouri
What's the difference between a DWI and a BAC charge in Missouri?
They're two separate criminal charges from one arrest. DWI under § 577.010 is about being intoxicated or impaired; the BAC charge under § 577.012 is the 'per se' offense of driving at 0.08% or higher regardless of how you seemed. Prosecutors often plead one and dismiss the other. To understand which you're facing and why it matters, call 1-844-690-0555 free, 24/7 for legal information — not advice.
I only have 15 days to do what, exactly?
To request an administrative hearing from the Missouri Department of Revenue, in writing, to fight the suspension of your license — and the 15 days run from your arrest date, not any court date. Miss it and the suspension takes effect on the 16th day with no hearing. Call 1-844-690-0555 now and we'll explain exactly how the request works, for free.
Can I still lose my license even if the criminal charge gets dropped?
Yes. The Department of Revenue suspension under § 302.505 runs on the arrest and test result alone, completely separate from the criminal case. Your charge could be reduced or dismissed and you could still lose your license if you missed the 15-day hearing window. That two-track split is why the free call at 1-844-690-0555 walks you through both.
What happens if I refused the breath or blood test?
Under Missouri's implied-consent law, § 577.041, refusing triggers an automatic one-year license revocation with no limited driving privilege for the first 90 days — and that's on top of the criminal case. You have 30 days from the Notice of Revocation to petition the circuit court in the county of arrest to review it. Call 1-844-690-0555 free, 24/7 to understand your options. This is information, not legal advice.
Will a first-offense DWI stay on my record forever?
Not necessarily. Missouri allows a Suspended Imposition of Sentence (SIS) on a first offense — complete probation and there's no conviction on your public record, though the arrest still shows in the Department of Revenue's alcohol-contact history and still counts as a prior on any future case. Preserving SIS is often a primary defense goal. Call 1-844-690-0555 to learn how it works, free and with no attorney-client relationship created.
How much jail time am I actually looking at for a first DWI?
A first offense is a Class B misdemeanor with up to 6 months county jail and/or up to a $500 fine, though SIS and probation often avoid jail entirely. A BAC of 0.15–0.20% adds a 48-hour mandatory minimum; over 0.20% adds 5 days. For how the ranges apply to your situation, call 1-844-690-0555 free, 24/7 for plain-English information.
When does a Missouri DWI become a felony?
On your third alcohol contact you become a 'Persistent Offender' facing a Class E felony — up to 4 years prison and up to a $10,000 fine — once you have two priors, at least one within the past ten years. A further offense as an 'Aggravated Offender' is a Class C felony (up to 7 years); a 'Chronic Offender' is a Class B felony (5 to 15 years). Call 1-844-690-0555 to understand where your prior contacts put you, for free.
Can I drive at all during my suspension?
It depends. A 90-day first-contact suspension is 'hard' for the first 30 days — no driving — then 60 days of restricted privilege with an ignition interlock. A refusal revocation gives you no privilege at all for the first 90 days. Reinstatement always requires SATOP, SR-22 insurance, and fees. Call 1-844-690-0555 free, 24/7 to map out your specific timeline.
Does a Missouri DWI affect my immigration status?
A single DWI generally isn't on its own a deportable or inadmissible crime under federal immigration law, but a DWI combined with child endangerment, drugs, or a repeat/felony pattern can trigger removability or inadmissibility — so non-citizens need parallel screening on the federal side (USCIS/the immigration court system, not the state court). The AI assistant can flag the issue and point you to the right help. Call 1-844-690-0555 free, 24/7 for information, not legal advice.
Do I qualify for a public defender for my DWI?
Maybe not. The Missouri State Public Defender applies a strict indigency test, and municipal or city-ordinance DWIs fall outside its system entirely — a real access-to-counsel gap. Before you assume you're covered, call 1-844-690-0555 free, 24/7 to understand your options, including arranging a paid consultation with a Missouri attorney if you want one.
Is the 15-day license clock really separate from my court date?
Completely. The 15-day clock is the Department of Revenue's administrative track and runs from your arrest date; your criminal court date is a different process on a different timetable and won't pause or extend it. People lose their license simply by watching the wrong clock. Call 1-844-690-0555 free, 24/7 and we'll tell you which deadline is yours and how the hearing request works.
