After an arrest, it’s easy to feel like everything is suddenly out of your hands. You’ve got a court date, a Notice of Suspension, and maybe a vague explanation from the officer about what happens to your license next. You leave wondering whether the suspension is already a done deal.
A DUI arrest is the start of a process, not the verdict.
Here’s the thing most people don’t realize in those first hours: you are now facing two separate cases, each with its own clock, and one of them can quietly cost you your license in about two weeks if you do nothing. As a DUI defense attorney team serving central Missouri, we’ve walked hundreds of Washington, Missouri drivers through this exact moment. This post is the step-by-step version of that conversation — what to say, what not to say, and what to do next. Plainly, specifically, and for Missouri.
What Do You Need to Know Before You Do Anything After a DUI Arrest?
A Missouri DUI arrest sets off two independent proceedings at once. One is the criminal case in court; the other is an administrative license case with the Missouri Department of Revenue that can suspend your driving privilege before you ever see a judge. Miss the deadline on the second one and you forfeit the right to fight it.
In Missouri, the charge is formally called DWI — driving while intoxicated — and it’s the same offense people mean when they say “DUI.” The legal blood alcohol threshold is.08% for adult drivers and.02% for drivers under 21. Here’s what you’ll want in hand before you plan your response:
Your Notice of Suspension (Form 2385): The date printed on it starts the 15-day clock for your license hearing — this is the single most time-sensitive piece of paper you own right now.
Your citation and court date: This drives the criminal side of the case, including your arraignment.
Your own written timeline: Where you were, when you were stopped, what the officer said and did, and whether you were read your rights. Details fade fast.
Any test results you were given: Breath test readings or notice that a blood or urine test was taken.
If you only remember one thing from this section, remember the number 15. That’s the window that closes first.
Step 1: Stay Quiet and Protect Your Rights at the Scene
Say as little as possible and never argue or resist. Provide your license, registration, and proof of insurance, stay polite, but decline to answer questions about how much you had to drink or where you were coming from. Politeness and silence are not the same as guilt.
Officers are trained to build a case from the moment they approach your window — your speech, your eyes, the smell of the car, and every answer you give. You are not required to submit to roadside field sobriety tests, and those tests are designed to produce evidence against you, not to help you. What you can’t undo later is a spontaneous admission. “I only had a couple” is one of the most damaging sentences we hear repeated back in police reports. The outcome you want from this step: no new evidence created by your own words.
Step 2: Understand the Two Separate Cases You Now Face
You are facing a criminal charge and a separate administrative action against your license, and they do not move together. The criminal case is decided in court; the license case is handled by the Missouri Department of Revenue on its own schedule. Winning or losing one does not automatically resolve the other.
This surprises almost everyone. You can beat the criminal charge and still lose your license if you ignored the administrative side — and vice versa. According to the Missouri Department of Revenue, the effective date of the suspension or revocation is 15 days after the arrest when you submitted to a test over the limit. That built-in delay is your only window to act. The outcome of this step is simple awareness: two cases, two clocks, two responses required.
Step 3: Request Your Administrative License Hearing Within 15 Days
Request your administrative hearing in writing within 15 days of the notice date, or the suspension takes effect automatically. You have 15 days from the date Form 2385 is issued to submit a written hearing request to the Department of Revenue’s General Counsel’s Office — by mail postmark or delivery.
This is the deadline that quietly wrecks people. If you gave a breath sample over.08%, a first suspension runs 90 days. In practice, that period is often structured as 30 days of no driving followed by 60 days of restricted driving for eligible first offenders.
If you refused the breath or blood test entirely, the stakes climb: refusal triggers a one-year license revocation under Missouri’s implied consent law, separate from anything the court does. Requesting the hearing pauses the suspension and forces the state to prove its case. The outcome of this step: your license stays valid while the hearing is pending, and you’ve preserved every argument for later.
Step 4: Prepare for Arraignment and Enter Your Plea
At arraignment, the court formally reads the DWI charge and asks how you plead — and in almost every case, you plead not guilty to preserve your options. A not-guilty plea keeps the door open to review the evidence, negotiate, or take the case to trial; it does not lock you into anything.
Pleading guilty at arraignment feels like getting it over with. It’s usually the most expensive shortcut available. A first Missouri DWI is a class B misdemeanor, which carries the possibility of jail time, fines, probation, and points that hit your license and insurance.
Under the DWI statutes as they stand in 2026 (Mo. Rev. Stat. §§ 577.010, 577.012, 302.525), prior offenses escalate the classification quickly — a second or third becomes a far more serious matter. This is the point where having counsel in your corner changes the trajectory of the case. The outcome of this step: a plea on the record that keeps every defense alive.
Step 5: Review and Challenge the Evidence Against You
The strongest DUI defenses come from scrutinizing how the evidence was gathered, not just what it shows. A DUI defense attorney examines three pressure points: whether the stop had lawful probable cause, whether field sobriety tests were administered by the book, and whether the breath instrument was properly calibrated and maintained. A failure in any one can suppress the evidence built on it.
breath machines and roadside tests are not infallible. Here’s what our team looks at closely:
Probable cause for the stop: If the officer lacked a valid legal reason to pull you over, everything that followed can be challenged as fruit of an unlawful stop.
Field sobriety test administration: The standardized tests have strict protocols. Uneven pavement, poor lighting, a medical condition, or an officer skipping steps all undermine the results.
Breathalyzer accuracy and calibration: Missouri requires breath instruments to be maintained and calibrated on a regular schedule. Missing maintenance logs or an out-of-window calibration can render a reading inadmissible.
Procedural errors: Was the 15-minute observation period honored before the breath test? Was implied consent properly explained? Small deviations carry big consequences.
The outcome of this step: a clear picture of which parts of the state’s case are solid and which are vulnerable — the foundation for every decision that follows.
Step 6: Weigh the Plea-Versus-Trial Decision
You choose based on the strength of the evidence, your prior record, and what a conviction would cost you long-term. If the stop, the tests, or the breath results have real weaknesses, trial or a hard negotiation may be the smart play; if the evidence is airtight, a negotiated resolution can limit the damage. There’s no one-size answer.
This is where the evidence review pays off. A conviction isn’t just the fine and the court date. In Missouri, a DWI conviction generally stays on your driving record for years and can affect employment, professional licenses, and insurance rates well beyond the sentence itself.
Second and subsequent offenses carry mandatory minimum jail or community service time and can rise to felony territory. When we sit down with a client in Washington, Missouri, we weigh the probability of suppressing key evidence against the certainty of a plea’s terms — and we tell you honestly which way the numbers point. The outcome of this step: a decision made on facts, not fear.
Step 7: Plan for Reinstatement and Life After the Case
Whether suspended or convicted, you map the path back to full driving privileges, including any restricted driving privilege, ignition interlock, and required reinstatement steps with the Department of Revenue. Speed matters because your first and most important deadline — the 15-day license hearing request — expires long before your criminal case is resolved. Wait too long and you lose the automatic right to contest the suspension, no matter how weak the underlying stop was. Evidence also degrades: witnesses forget, dashcam footage gets overwritten, and calibration records become harder to obtain.
There’s a second reason. The Request for Immediate 90-Day Restricted Driving Privilege must be submitted within 15 days of receiving your notice if you want to keep driving to work and school during a suspension. Two critical 15-day windows, both starting at your arrest.
For working people across Franklin, Warren, Crawford, and Gasconade counties, losing the ability to drive isn’t an inconvenience — it’s a threat to your paycheck. Calling a criminal defense attorney before your first court date is the difference between reacting and being prepared. The takeaway: the earlier you engage, the more options you still have.
What Are the Most Common Mistakes People Make After a DUI Arrest?
The most common mistake is doing nothing and letting the 15-day license window close. The second is assuming the criminal case and the license case are the same thing and that resolving one handles both. Both errors are avoidable, and both are costly.
Here are the ones we see most often:
Missing the 15-day hearing request: This is the single most damaging misstep. It surrenders your license fight before it starts.
Talking too much: Explaining yourself to the officer, the prosecutor, or on social media almost always adds evidence, never removes it.
Pleading guilty to “just get it over with”: A conviction follows you for years on your record and your insurance — long after the case feels finished.
Assuming a breath reading is unbeatable: Calibration, maintenance, and administration errors happen more often than people expect.
Waiting until the court date to find a lawyer: By then, the license deadline has usually passed and early evidence may be gone.
Avoid these five and you’ve already improved your position more than most people who go through this process alone.
When Should You Call a DUI Defense Attorney Instead of Handling It Yourself?
Call a DUI defense attorney immediately — before your arraignment and well inside the 15-day license window. A DUI in Missouri involves two overlapping legal proceedings, strict deadlines, technical breath-test rules, and consequences that outlast the sentence, which makes it one of the worst charges to face without counsel. This is not a traffic ticket you contest at the counter.
You especially need a lawyer if any of these apply: you refused chemical testing and face a one-year revocation, you have a prior DWI, there was an accident or injury, your job requires driving or a clean record, or you simply don’t know whether the stop was lawful. Brandt Law, LLC handles criminal defense litigation — the courtroom process of challenging the state’s evidence and protecting your rights from arrest through resolution — for drivers across central Missouri. If you’re weighing whether the cost of a defense is worth it, compare it to years of higher insurance premiums, lost driving privileges, and a conviction on your permanent record. The honest answer for most people: the earlier you call, the more we can do.
FAQ: DUI and DWI Defense Questions for Missouri Drivers
How long do I have to save my license after a DUI arrest in Missouri?
You have 15 days from the date your Notice of Suspension (Form 2385) is issued to submit a written request for an administrative hearing to the Missouri Department of Revenue. Missing this deadline means the suspension takes effect automatically and you lose the right to contest it before it starts. This clock runs completely separately from your criminal court date, so acting fast is essential.
What is the difference between a DUI and a DWI in Missouri?
In Missouri, the official charge is DWI — driving while intoxicated — and it’s the same offense most people call a DUI. The terms are used interchangeably by the public, but state statutes and courts use DWI. The legal blood alcohol limit is.08% for drivers 21 and over, and.02% for drivers under 21, with penalties escalating for higher readings and repeat offenses.
Can I refuse a breathalyzer in Missouri?
You can physically refuse, but Missouri’s implied consent law treats refusal as a separate violation that triggers an automatic one-year license revocation, effective independently of your criminal case. By driving on Missouri roads, you’ve already given implied consent to chemical testing after a lawful arrest. Refusal doesn’t make the DWI charge disappear, and prosecutors can use the refusal itself as evidence, so this decision has serious consequences.
What happens at a DWI arraignment?
At arraignment, the court formally reads the charge against you and asks how you plead. In the vast majority of cases, entering a not-guilty plea is the right move because it preserves your ability to review the evidence, negotiate, and take the case to trial if needed. Pleading guilty at this stage forfeits those options and locks in a conviction, so having an attorney in place beforehand matters.
How much does a first-offense DWI cost in Missouri?
A first DWI in Missouri is a class B misdemeanor, which can carry jail time, fines, court costs, and probation, plus a 90-day license suspension for a test over.08%. The true cost runs far higher than the fine, though — years of increased insurance premiums, reinstatement fees, and a mark on your record all add up. That long tail is exactly why fighting the charge often costs less than accepting it.
Can a breathalyzer result be challenged in court?
Yes, breath test results are regularly challenged and sometimes thrown out. Missouri requires breath instruments to be calibrated and maintained on a set schedule, and officers must follow strict administration procedures, including an observation period before the test. Missing maintenance records, an expired calibration, or a skipped protocol step can make a reading inadmissible. A defense attorney knows how to request and scrutinize these records.
When should I hire a DUI defense attorney after an arrest?
Hire one immediately — ideally within the first day or two, well inside the 15-day license hearing window and before your arraignment. Early involvement lets your attorney request the administrative hearing, preserve evidence like dashcam footage and calibration logs before it disappears, and shape your plea strategy. Waiting until your court date usually means the most important deadline has already passed and key evidence may be gone.
