A DWI arrest in Missouri moves fast. Within minutes, you are looking at criminal charges, a threatened driver's license suspension, and a 15-day window to protect your driving privileges before the Department of Revenue acts automatically. If you were arrested for driving while intoxicated in Columbia, Boone County, or anywhere across central Missouri, the decisions made in the first days after your arrest matter more than most people realize. Bur Oak Legal defends DWI charges across mid Missouri — one attorney, no handoffs, from the administrative hearing through trial if that's where it goes.
(573) 499-0200 — call anytimeMissouri uses the term DWI — driving while intoxicated — rather than DUI. Both terms describe the same conduct, but Missouri law and Missouri courts use DWI. Under § 577.010 RSMo, a person commits the offense of driving while intoxicated when they operate a motor vehicle while in an intoxicated condition. Under § 577.012 RSMo, driving with a blood alcohol content of 0.08 percent or above is a per se violation — meaning the blood or breath test result alone is enough evidence for the charge, regardless of whether the officer observed impaired driving.
For commercial driver's license holders, the BAC threshold drops to 0.04 percent. A DWI charge can be based on alcohol, controlled substances, or any combination of intoxicants that impair the driver's ability to safely operate a vehicle.
When a Missouri police officer arrests you for DWI and your breath test or blood test shows a BAC at or above the legal limit — or you refused testing — the Missouri Department of Revenue moves to suspend your driving privileges administratively. This process runs parallel to the criminal case and operates on its own timeline.
You have 15 days from the date of arrest to request an administrative hearing. Miss that window and the suspension becomes automatic — and there is no coming back from it once the deadline passes. This is one of the most time-sensitive obligations that follows a DWI arrest, and most people do not know about it until it is too late.
At Bur Oak Legal, Chris requests that hearing immediately after being retained. The administrative hearing is a separate fight to protect your license, and it is one most people do not know they have to fight separately from the criminal charge.
The administrative hearing is also valuable for another reason: it is one of the few opportunities to question the arresting officer under oath before the criminal case proceeds. What comes out in that hearing can inform the defense strategy in the criminal matter.
The administrative hearing before the Department of Revenue focuses on a narrow set of issues: whether there was probable cause for the arrest, whether the implied consent law was followed correctly, and whether the test results are legally sufficient to support the revocation. These are legal questions — and they are exactly the kind of questions an experienced attorney is positioned to challenge.
Missouri's implied consent law means that by driving on Missouri roads, you have already agreed to submit to a chemical test if lawfully arrested for DWI. Refusing a breathalyzer test or blood test is your right — but it carries consequences. A refusal triggers a one-year license revocation for a first offense, compared to a 30-day suspension for drivers who take the test and fail.
That said, refusing a test is not automatically the wrong choice, and the decision depends heavily on the circumstances of your arrest. Whether the stop was lawful, whether the officer had actual probable cause, and whether the implied consent advisory was delivered correctly are all questions that matter — and all questions an experienced DWI attorney evaluates before advising on strategy.
Breathalyzer test results depend on the machine being properly calibrated and maintained, the test being administered according to protocol, and no interference from other compounds. Mouth alcohol, certain medical conditions, and some medications can produce readings that appear elevated. Calibration records and maintenance logs are discoverable and often worth examining.
Blood test results involve a separate chain of custody question: from the draw, to the storage, to the analysis at the lab. Any break in that chain creates a question about whether the sample tested was actually the defendant's blood — and whether it was handled in a way that preserves the integrity of the result.
Not every DWI charge results in a conviction. The state must prove every element of the offense beyond a reasonable doubt, and there are multiple points in a DWI case where the evidence can be challenged. An experienced DWI attorney reviews the complete record — from the initial stop through the test administration — before assessing what defenses apply.
A DWI conviction in Missouri carries consequences that extend well past any sentence the judge imposes. Understanding the full picture of what is at stake — before the case is resolved — is part of building the right defense strategy.
Insurance premiums typically increase substantially after a DWI conviction and can remain elevated for years. Missouri allows insurers to classify a DWI as a major violation and rate accordingly. Some insurers will non-renew a policy following a DWI conviction, forcing a driver into the high-risk market.
A CDL holder faces federal disqualification rules that operate independently of Missouri law. A first DWI offense — even in a personal vehicle — can result in a one-year CDL disqualification. A second offense triggers lifetime disqualification from operating a commercial vehicle. For professional drivers, a DWI charge is effectively a career threat.
Missouri allows expungement of some DWI convictions, but eligibility depends heavily on how the case was resolved. A suspended imposition of sentence — where the court withholds a formal conviction pending completion of probation — is treated differently than a straight conviction and may open the expungement process sooner. First time offenders who handle their case correctly from the start preserve more options later.
A DWI conviction can affect professional licenses — nursing, teaching, commercial driving, law enforcement — depending on the licensing board's rules. It appears on standard background checks and can affect employment decisions, particularly for positions involving driving, security clearances, or work with vulnerable populations.
Chris Miller has appeared before the Missouri Supreme Court and won — expanding rights for Missourians in a case that changed state law. That experience in high-stakes advocacy applies directly to DWI defense, where the margin between a conviction and a dismissal can come down to a single procedural challenge or an overlooked calibration record.
