Leading felony DWI lawyer in Boone County, MO. A DWI arrest in Boone County, MO is serious under any circumstances. But when a drunk or drugged driving charge becomes a felony, the stakes change dramatically. Instead of dealing primarily with the possibility of fines, probation, and a temporary driver’s license suspension, you could be facing years in prison, a felony criminal record, and collateral consequences that can follow you for the rest of your life.
Defending a felony DWI case can require challenging several different parts of the prosecution’s case. Prosecutors may point to prior DWI convictions, breath or blood test results, officer observations, field sobriety testing, medical records, crash reconstruction evidence, or allegations that impaired driving caused serious injuries or death. Your defense may therefore need to address not only whether you were impaired, but also whether the state can prove the circumstances necessary to prosecute the offense as a felony.
At Combs Waterkotte, our criminal defense attorneys defend clients against serious DWI allegations throughout Boone County 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’re facing felony DWI charges in or around Boone County, MO, call Combs Waterkotte right away at (314) 900-HELP or reach out online to schedule a free, confidential consultation with an experienced DWI defense attorney.

What You Need to Know About Felony DWI in Boone County, MO
A felony DWI charge in the Boone County, 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:
- How misdemeanor DWI allegations can become felony charges and what circumstances Missouri law considers when determining the severity of an offense
- Missouri’s repeat DWI offender classifications, including persistent, aggravated, chronic, and habitual DWI offenders
- How serious felony DWI penalties can become, including felony classifications, prison exposure, and restrictions on probation or parole
- How serious injuries or fatalities can affect DWI charges and why causation may become a critical issue in these cases
- How the government attempts to establish intoxication and criminal responsibility through breath tests, blood tests, field sobriety tests, video recordings, witnesses, and accident evidence
- Where weaknesses may exist in a felony DWI case, including problems with the initial stop, chemical testing procedures, evidence, or alleged prior offenses
- How a DWI arrest can affect your driver’s license separately from the criminal prosecution from defending against the underlying criminal charge
- How a felony DWI lawyer in Boone County, MO can help , from investigating the arrest and preserving evidence to challenging the prosecution’s allegations
The more serious a DWI charge becomes, the more important it is to examine every part of the government’s allegations. The Boone County, MO defense attorneys at Combs Waterkotte investigate felony DWI cases from every angle, looking closely at the evidence prosecutors intend to use and the circumstances they claim justify enhanced charges.
Why Are Some DWI Charges Felonies in Boone County, MO?
Missouri does not treat every DWI offense the same. A person facing a first DWI in Boone County, MO will generally face a misdemeanor when the case does not involve circumstances supporting a more serious charge. Under Missouri Revised Statute § 577.010, however, prior offenses and certain aggravating circumstances can expose a defendant to significantly greater penalties.
A driver’s prior intoxication-related traffic offenses can play a major role in determining the severity of a new DWI charge. Prosecutors may also look at what happened during the alleged offense itself. Factors that can increase the seriousness of a DWI case in Boone County, MO include:
- A 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.
- Injury or Death: 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: Having a passenger younger than 17 while allegedly driving intoxicated can result in a Class A misdemeanor on a first offense and felony consequences for a subsequent occurrence.
- Additional Driving or Testing Issues: Allegations involving driving while suspended or revoked or refusing a chemical test can create additional legal and licensing consequences.
As a result, a felony DWI defense can involve multiple issues at the same time. A Boone County, MO DUI defense attorney may challenge the evidence that you were intoxicated while separately contesting the prior convictions, injury allegations, or other factors the prosecution claims support felony-level charges.

Below are quick links to important websites that may assist you with your legal matters in Boone County and Missouri.
Boone County, MO Felony DWI Charges Based on Prior Offenses
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 Boone County, MO
Missouri may classify a defendant as a persistent offender when their record contains qualifying prior intoxication-related traffic offenses. Meeting the statutory requirements for persistent offender status can elevate the current DWI beyond an ordinary misdemeanor and expose the defendant to felony-level penalties.
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 Boone County, MO
Chronic offender status represents another significant increase in the severity of a Missouri repeat DWI case. Prosecutors pursuing this classification may seek substantial prison time, which makes it especially important to determine whether the prior offenses being used against the defendant meet the statutory requirements.
Habitual Offender
Habitual offender status is reserved for some of the most serious repeat DWI cases prosecuted in Boone County, MO. The potential consequences include a high-level felony conviction and significant prison time. However, prosecutors must do more than point to a history of DWI arrests or convictions—they must establish that the prior offenses satisfy the legal requirements for the enhancement they are seeking.
Our DWI attorneys in Boone County, MO carefully review prior court records, charging documents, plea records, dispositions, and other relevant evidence to determine whether the prosecution can legally establish the repeat-offender classification alleged in your case.
How Repeat DWI Offender Status Affects Penalties in Missouri
Missouri’s DWI penalties become increasingly severe when a defendant has qualifying prior intoxication-related traffic offenses. In Boone County, MO, persistent offender status can elevate a DWI to a felony, while aggravated, chronic, and habitual offender classifications can expose defendants to progressively higher felony levels and substantially longer prison sentences.
| Offender Classification | Prior Offense History | Level of Offense | 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 |
Remember: 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.
The consequences of a felony DWI in Boone County, MO can continue long after the criminal sentence ends. A conviction may interfere with employment, professional licensing, housing, education, immigration consequences, firearm rights, and other aspects of your life. Repeat DWI convictions can also make any future intoxication-related driving allegation substantially more dangerous.
Because both the immediate sentence and long-term consequences can be substantial, you should consider involving an experienced Boone County, MO DWI defense attorney as early in the process as possible.
When a DWI Causes Serious Physical Injury in Boone County, MO
When another person suffers serious injuries in an alleged impaired-driving crash, what might otherwise be a less serious DWI case in Boone County, MO, can carry dramatically greater criminal exposure. Depending on the accident, the injured person could be:
- Another motorist
- Passengers
- Pedestrians
- Bicyclists
- A motorcyclist
- Emergency responders
- A worker in a highway or construction zone
- Other people injured in or around the crash
The existence of an injury does not automatically establish criminal responsibility. Prosecutors still have to connect the defendant’s alleged intoxication and conduct to the injury. That makes causation a critical issue in many felony DWI accident cases.
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 Boone County, 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
- Dash-camera or surveillance video
- Damage to the vehicles
- Event data recorder information
- Witness testimony
- Toxicology results
- Accident reconstruction findings
- The actions of other drivers involved in the collison
The difference between being involved in a fatal accident and criminally causing a death while intoxicated is legally significant. When necessary, our DWI defense attorneys in Boone County, MO can work with investigators and expert witnesses to scrutinize the government’s reconstruction of the collision.
How Prosecutors Try to Prove Felony DWI Cases in Boone County, 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:
- Police observations and reports
- Dash-camera recordings
- Body-camera footage
- Field sobriety test results
- Breathalyzer test results
- Blood and urine analysis
- Hospital records
- Eyewitness accounts
- 911 calls and dispatch recordings
- Business, residential, or traffic surveillance footage
- Vehicle data
- Cellphone data and records
- Accident reconstruction reports
- Documentation concerning alleged prior DWIs
The existence of this evidence does not necessarily mean that it is accurate, reliable, or sufficient to prove a felony DWI charge.
Every category of evidence can raise its own questions. An officer’s recollection may conflict with camera footage. A witness may have seen only part of what happened. Field sobriety tests may have been conducted under poor conditions or administered incorrectly. Chemical testing can involve equipment or procedural errors, while accident reconstruction conclusions may change when additional evidence is considered. A careful defense investigation can test whether the prosecution’s evidence actually supports the conclusions the government claims it does.
How Reliable Are Breath and Blood Tests in Boone County, MO DWI Cases?
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.
Potential areas of concern can include:
- Improper breathalyzer calibration
- Malfunctioning or improperly maintained testing equipment
- Failure to follow established testing procedures
- Possible contamination of blood evidence
- Improper sample storage
- Problems with the chain of custody
- A significant delay between the alleged driving and chemical testing
- Laboratory testing or reporting errors
- Medical conditions that may affect test results
- Questions about how toxicology findings were interpreted
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 Boone County, 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 Boone County, 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.
Depending on those circumstances, defense strategies for winning your DWI case may focus on issues such as:
Challenging the Legality of the Traffic Stop
Police generally need a lawful basis to stop a vehicle. When officers lack sufficient legal justification for a traffic stop in the Boone County, MO area, evidence obtained afterward may be subject to suppression.
When important evidence is suppressed, it can significantly weaken the prosecution’s ability to prove the charge.
The Chemical Test Was Unreliable
Breath and blood testing procedures are technical, but they are not infallible. Your attorney can investigate whether equipment, personnel, laboratory procedures, and sample handling complied with applicable requirements.
The State’s Evidence Does Not Prove Impairment
Many behaviors police associate with intoxication can have other explanations. Fatigue, anxiety, physical injuries, medical conditions, confusion, and nervousness can all affect how someone speaks, moves, or responds during an encounter with law enforcement.
Video recordings can be particularly valuable because they allow the defense, prosecutors, and ultimately a court or jury to compare what actually occurred with what officers described in their reports.
The Defendant Did Not Cause the Crash
When a felony DWI prosecution involves serious injury or death, establishing intoxication may be only one part of the government’s case. Prosecutors may also need to prove that the defendant’s conduct legally caused the resulting harm.
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.
A prior offense may not qualify in the way prosecutors claim, or the state may have difficulty establishing the records necessary to prove the enhancement.
What Should You Do After a Felony DWI Arrest in Boone County, MO?
The decisions you make immediately after an arrest can affect what happens later. If you are accused of felony DWI in or around Boone County, MO, you should follow these steps:
Step 1: Do Not Discuss the Facts of Your Case With Investigators Without Legal Counsel
After a felony DWI arrest, you may be contacted by police, investigators, or other authorities looking for additional information. Even statements that seem harmless could potentially be used to strengthen the prosecution’s case. Exercise your right to remain silent and speak with your Boone County, MO felony DWI defense attorney before answering questions about the incident.
Step 2: Keep the Details of Your Case Off Social Media
Avoid discussing your DWI arrest, the events leading up to it, an accident, or anyone else involved on social media. Photos, comments, messages, check-ins, and other online activity could potentially become evidence. It is generally safest to keep the details of your pending case offline.
Step 3: Preserve All 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: Keep All Court Paperwork and Driver’s License Documents
Save every citation, court notice, bond document, driver’s license notice, and other piece of paperwork associated with your arrest. A felony DWI case in Boone County, MO may involve criminal proceedings as well as separate administrative driver’s license proceedings. Some documents may contain deadlines that require prompt action.
Step 5: Get a Felony DWI Lawyer in Boone County, MO Involved Early
The evidence in a felony DWI prosecution can range from chemical testing and prior court records to crash reconstruction, video recordings, and witness testimony. Contacting an experienced Boone County, MO felony DWI attorney early gives your defense team more time to preserve evidence, investigate the allegations, identify potential weaknesses, and prepare a strategy for the proceedings ahead.
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.
