Leading felony DWI lawyer in Union, MO. A DWI arrest in Union, MO can put your license, freedom, and future at risk. When the allegations rise to the level of a felony, however, the potential repercussions become substantially more severe. A felony drunk or drugged driving charge can expose you to years behind bars, a permanent felony record, and significant collateral consequences that may affect your career, finances, and opportunities long after the criminal case ends.
The seriousness of a felony DWI prosecution also means there may be significantly more evidence to investigate. The state could build its case around previous DWI convictions, breath and blood tests, statements made during the arrest, police video, field sobriety tests, medical evidence, accident reconstruction, and allegations involving serious physical injury or a fatality. Each piece of evidence, and the allegations being used to justify felony treatment, deserves careful scrutiny.
At Combs Waterkotte, our criminal defense attorneys defend clients against serious DWI allegations throughout Union and across Missouri. We examine how the investigation began, what happened during the traffic stop and arrest, how chemical testing was conducted, whether prior offenses can support an enhancement, and what evidence exists for every aggravating allegation. Prosecutors carry the burden of proving the charges beyond a reasonable doubt, and we work to hold them to that burden at every stage of the case.
If you have been charged with felony DWI in or around Union, MO, call Combs Waterkotte at (314) 900-HELP or contact us online for a free, confidential consultation with an experienced DWI defense attorney.

What You’ll Learn on This Page About Union, MO Felony DWI Lawyers
A felony DWI charge in the Union, MO area carries consequences that go far beyond those associated with a typical first-time impaired driving offense. Whether you are facing charges because of prior DWI convictions, a serious accident, or allegations involving injury or death, understanding how Missouri classifies and prosecutes felony DWI cases is critical to protecting your future.
Below, we break down the major issues that can shape a felony DWI prosecution, including:
- What can elevate a Missouri DWI to a felony, and what circumstances Missouri law considers when determining the severity of an offense
- How repeat offenders are categorized under Missouri law, including persistent, aggravated, chronic, and habitual offender classifications
- The potential penalties for felony DWI, including the applicable felony levels, potential incarceration, and certain restrictions on early release
- How serious injuries or fatalities can affect DWI charges and why determining who or what caused a collision can become central to the case
- What evidence may be used to build the state’s case through breath tests, blood tests, field sobriety tests, video recordings, witnesses, and accident evidence
- Where weaknesses may exist in a felony DWI case, from unlawful traffic stops and unreliable chemical testing to problems with prior-offense enhancements
- How a DWI arrest can affect your driver’s license separately from the criminal prosecution from defending against the underlying criminal charge
- How working with a felony DWI attorney in Union, MO can affect your case , particularly when substantial prison exposure and a permanent felony record are at stake
Felony DWI cases can expose defendants to years in prison and consequences that extend well beyond the courtroom. The Union, MO defense attorneys at Combs Waterkotte can examine every part of the prosecution’s case and develop a defense strategy based on the specific facts and evidence involved.
What Can Elevate a DWI to a Felony in Union, MO?
Not every DWI in Union, MO is a felony. A first-time DWI is generally prosecuted as a misdemeanor when no circumstances exist that justify more serious charges. However, under Missouri Revised Statute § 577.010, the severity of DWI charges increases when certain aggravating factors are present.
Prosecutors will typically examine both your previous driving record and the facts surrounding the current arrest when determining what charges to pursue. Circumstances that can make a DWI case considerably more serious in Union, MO include:
- High Blood Alcohol Concentration (BAC): A BAC level of .15 or higher increases penalties and restricts alternative sentencing options.
- Prior DWI-Related Offenses: Multiple previous intoxication-related traffic offenses can result in repeat-offender classifications and potentially elevate a new DWI to a felony.
- Serious Injury or Fatality: Allegations that criminally negligent impaired driving caused physical injury or death can substantially increase the severity of the prosecution, including cases involving law enforcement officers, emergency personnel, or other individuals.
- Minor Passenger: Driving while intoxicated with a passenger under 17 can make a first offense a Class A misdemeanor, while a subsequent offense can result in felony exposure.
- Additional Driving or Testing Issues: Allegations involving driving while suspended or revoked or refusing a chemical test can create additional legal and licensing consequences.
This means defending a felony DWI may require challenging more than the state’s evidence of intoxication. Your Union, MO DUI defense attorney may also need to scrutinize the prior offenses, alleged injuries, or other circumstances prosecutors are relying on to justify the enhanced charge.

How Prior DWI Offenses Can Lead to Felony Charges in Union, MO
Missouri uses different classifications for repeat DWI offenders. These classifications become increasingly serious as qualifying prior offenses accumulate. Under RSMo § 577.023, these classifications are:
Persistent Offender in Union, MO
A person may face enhanced DWI charges as a persistent offender based on qualifying prior intoxication-related traffic offenses. A DWI prosecuted under this classification can become a felony, exposing the defendant to substantially greater consequences than those associated with an ordinary misdemeanor DWI.
Union, MO Aggravated Offender
Aggravated offender status applies to defendants with a more substantial history of qualifying intoxication-related traffic offenses or certain serious prior DWI-related offenses. The designation increases the severity of the felony charge and can result in greater potential prison exposure.
Chronic Offender in Union, MO
A defendant who meets Missouri’s requirements for chronic offender status faces an even higher level of felony DWI prosecution. Because this classification can carry substantial incarceration, determining whether each alleged prior offense actually qualifies under Missouri law can become a central part of the defense.
Union, MO Habitual Offender
The habitual offender classification applies to some of Union, MO’s most serious repeat DWI prosecutions. A conviction can expose the defendant to severe felony penalties and significant incarceration. The prosecution cannot simply claim that you have prior DWIs and automatically receive an enhanced conviction. The government must establish that the alleged prior offenses legally qualify for the enhancement being sought.
Our DWI attorneys in Union, MO examine court records, charging documents, dispositions, plea records, and other evidence surrounding prior cases to determine whether prosecutors can actually establish the required offender classification.
Missouri Felony DWI Penalties by Offender Classification
Missouri increases DWI penalties based on a defendant’s history of intoxication-related traffic offenses. Once a person qualifies as a persistent offender in Union, MO, a DWI can be prosecuted as a felony. More extensive DWI histories can result in progressively more serious felony classifications and longer potential prison sentences.
| Offender Classification | Qualifying Offense History | DWI Classification | Possible Prison Term | Minimum Time Before Parole or Probation |
|---|---|---|---|---|
| Prior Offender | One prior intoxication-related traffic offense within the applicable 5-year period | Class A misdemeanor | Up to 1 year | Generally 10 days, subject to statutory community service or treatment alternatives |
| Persistent Offender | Two or more intoxication-related traffic offenses committed on separate occasions, or certain prior intoxication-related offenses involving injury or death | Class E felony | Up to 4 years | Generally 30 days, subject to statutory community service or treatment alternatives |
| Aggravated Offender | Three or more intoxication-related traffic offenses, or qualifying combinations involving prior DWI offenses that caused injury or death | Class D felony | Up to 7 years | At least 60 days |
| Chronic Offender | Four or more intoxication-related traffic offenses, or certain combinations of prior offenses involving injury or death | Class C felony | 3 to 10 years | At least 2 years |
| Habitual Offender | Five or more intoxication-related traffic offenses, or certain combinations of prior offenses involving injury or death | Class B felony | 5 to 15 years | At least 2 years |
Important: A defendant’s offender classification is more complicated than simply looking at the total number of prior DWI convictions. Missouri also considers certain intoxication-related offenses that resulted in injury or death. Those offenses can affect whether someone meets the statutory requirements for persistent, aggravated, chronic, or habitual offender status.
A felony DWI conviction in Union, MO can also create problems long after any prison sentence, probation, or parole has ended. A felony record may affect your ability to secure employment, maintain professional licenses, obtain housing, pursue educational opportunities, address immigration matters, or exercise certain firearm rights. A felony DWI can also increase the stakes considerably if you are accused of another intoxication-related driving offense later.
Because both the immediate sentence and long-term consequences can be substantial, you should consider involving an experienced Union, MO DWI defense attorney as early in the process as possible.
When a DWI Causes Serious Physical Injury in Union, MO
A DWI in Union, MO can become significantly more serious when prosecutors allege that impaired driving caused another person’s injuries. These cases may arise from collisions involving:
- Other drivers
- A passenger
- Pedestrians
- Bicyclists
- Motorcyclists
- Emergency responders
- A worker in a highway or construction zone
- Another person affected by the collision
However, the fact that someone was injured does not, by itself, prove that the defendant was criminally responsible for those injuries. Prosecutors must establish the necessary connection between the alleged impaired driving, the collision, and the resulting harm. For that reason, determining what actually caused the crash can become one of the most important issues in a felony DWI case.
A collision may have involved another motorist speeding, disregarding a traffic signal, making an unsafe lane change, or engaging in other conduct that contributed to the accident. Poor road conditions, limited visibility, mechanical problems, and additional circumstances can also influence how and why a crash occurred. A thorough felony DWI defense therefore needs to look beyond BAC results and examine the evidence surrounding the collision itself.
Felony DWI Cases Involving a Fatality in Union, MO
A fatal collision can turn a DWI prosecution into an exceptionally high-stakes criminal case. The loss of life understandably makes these cases emotionally charged, and prosecutors may pursue severe penalties. For the person accused, a conviction can mean substantial incarceration and consequences that permanently alter their future.
But a fatality does not eliminate the prosecution’s burden of proof. A defense investigation may examine:
- The sequence of events leading to the crash
- The speeds of the vehicles involved
- Braking and steering inputs
- Traffic lights, signs, and right-of-way issues
- Weather, lighting, and roadway conditions
- Surveillance or dash-camera footage
- Damage to the vehicles
- Event data recorder information
- Eyewitness accounts
- Toxicology evidence
- Accident reconstruction evidence
- The actions of other drivers involved in the collison
There is an important legal distinction between being involved in an accident in which someone dies and being criminally responsible for causing that death while intoxicated. When the circumstances require it, our DWI defense attorneys in Union, MO can work with investigators and expert witnesses to independently examine the collision and challenge weaknesses in the government’s accident reconstruction.
Building a Felony DWI Case: Evidence Prosecutors May Use in Union, MO
When prosecutors pursue felony DWI charges, they may draw from numerous sources of evidence rather than relying solely on what happened during the initial traffic stop. Serious accidents and repeat-offender cases can generate extensive records, recordings, test results, and other evidence, including:
- Officer observations
- Dash-cam video
- Body-camera footage
- Field sobriety test results
- Breath alcohol testing
- Blood and urine analysis
- Medical and hospital records
- Eyewitness accounts
- 911 recordings
- Surveillance video
- Vehicle data
- Cellphone records
- Accident reconstruction
- Prior DWI records
Having evidence and proving a felony DWI beyond a reasonable doubt are not the same thing.
Chemical tests can be challenged. Police observations can be contradicted by video. Witnesses can be mistaken. Field sobriety testing can be improperly administered. Accident reconstructions can rely on questionable assumptions. A felony conviction should not rest on evidence that cannot withstand careful scrutiny.
Can Breath or Blood Test Results Be Challenged in Union, MO?
Prosecutors often rely heavily on BAC evidence, particularly when a breath or blood test appears to show a result above the legal limit. But a chemical test result is only as reliable as the equipment, procedures, sample handling, and analysis used to produce it. Problems at any stage of the testing process may raise legitimate questions about whether the result accurately reflects a defendant’s BAC.
Issues that may warrant further investigation include:
- Breathalyzer calibration problems
- Whether the testing equipment was functioning correctly
- Failure to follow established testing procedures
- Possible contamination of blood evidence
- Improper sample storage
- Problems with the chain of custody
- Delays between driving and testing
- Laboratory testing or reporting errors
- Medical conditions affecting results
- Whether toxicology results were interpreted correctly
Blood testing can become particularly important in felony cases arising from serious crashes because an injured driver may have blood drawn at a hospital. Your Union, MO felony DWI lawyer can investigate where the sample came from, why it was collected, how it was tested, who handled it, and whether the prosecution can lawfully use the results against you.

Potential Strategies for Defending a Felony DWI in Union, MO
Every felony DWI case presents different legal and factual issues. The strongest defense strategy will depend on the circumstances surrounding the traffic stop or accident, the observations made by law enforcement, the chemical testing involved, and the specific allegations prosecutors are using to pursue felony-level charges.
Potential defense strategies for winning your DWI case may involve the following:
There Was No Lawful Basis for the Stop
Police generally need a lawful basis to stop a vehicle. When officers lack sufficient legal justification for a traffic stop in the Union, MO area, evidence obtained afterward may be subject to suppression.
If critical evidence is suppressed, prosecutors may have difficulty proceeding with the case.
Breath or Blood Evidence Cannot Be Trusted
Breath and blood tests can play a major role in a felony DWI prosecution, but these testing methods are not infallible. A defense investigation can examine the testing equipment, operator qualifications, laboratory procedures, sample handling, maintenance records, and other factors that may affect the reliability of the results.
The State’s Evidence Does Not Prove Impairment
A person can appear tired, confused, nervous, injured, or unsteady for reasons unrelated to intoxication.
Dash-camera and body-camera recordings may also provide objective evidence that contradicts or places an officer’s observations into a different context.
The State Cannot Prove Causation
Felony DWI cases involving injury or death can require prosecutors to establish a connection between the defendant’s alleged conduct and the resulting harm. Simply being intoxicated and involved in an accident may not resolve the question of causation.
Physical evidence, crash reconstruction, road conditions, vehicle defects, and the conduct of other motorists may show that additional factors caused or contributed to the collision.
The Alleged Prior Offenses Do Not Justify Felony Treatment
A repeat-offender enhancement depends on qualifying prior intoxication-related offenses. That makes the defendant’s criminal and driving history an important area of investigation rather than something that should simply be accepted as presented by prosecutors.
Reviewing court files, dispositions, plea records, and other documentation may reveal that an alleged prior offense does not qualify for the enhancement or that prosecutors cannot establish the necessary prior record.
What to Do Next After a Felony DWI Arrest in Union, MO
The decisions you make immediately after an arrest can affect what happens later. If you are accused of felony DWI in or around Union, MO, you should follow these steps:
Step 1: Protect Your Right to Remain Silent
Investigators may continue seeking information after your arrest, particularly when the case involves a serious collision, injury, or death. Statements you make could later become part of the evidence prosecutors attempt to use against you. Exercise your right to remain silent and talk to your Union, MO felony DWI defense attorney before discussing the allegations with investigators.
Step 2: Keep the Details of Your Case Off Social Media
Social media can create evidence that did not otherwise exist. Posts, photographs, comments, videos, location information, and conversations about the arrest or accident may be taken out of context or used during the prosecution. Avoid posting details about the case while it remains pending.
Step 3: Save Anything That May Become Evidence
Save anything that could help establish where you were, what happened, and the circumstances surrounding your arrest. This might include photographs, videos, text messages, receipts, rideshare records, or other relevant information. Seemingly minor details can become important when your attorney investigates the prosecution’s version of events.
Step 4: Organize Your Court and Driver’s License Documents
Do not throw away notices, citations, bond paperwork, court documents, or driver’s license correspondence you receive following your arrest. A DWI in Union, MO can involve both a criminal case and separate administrative driver’s license proceedings. These documents may contain important deadlines and information your attorney needs to review.
Step 5: Speak With an Experienced Union Felony DWI Defense Attorney as Soon as Possible
Felony DWI cases can involve chemical testing, prior convictions, accident reconstruction, witness testimony, video evidence, and serious sentencing exposure. Getting a knowledgeable Union, MO felony DWI attorney involved early provides more time to investigate what happened, preserve favorable evidence, examine the state’s allegations, and begin developing your defense.
Evidence can become harder to locate as time passes, while law enforcement and prosecutors may already be developing their case. Starting your defense promptly can provide additional opportunities to secure favorable evidence and identify legal or factual problems with the allegations.
