Felony DWI Lawyer Franklin County, MO

Verified Content

Last Updated: August 17, 2026

Leading felony DWI lawyer in Franklin County, MO. A DWI arrest in Franklin 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.

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 represent people facing serious DWI charges throughout the Franklin County area and across Missouri. We investigate the traffic stop, arrest, chemical testing, prior convictions, and every aggravating allegation prosecutors intend to use against you. When your freedom and future are on the line, you need someone on your side fighting to make sure the government is required to prove every element of its case beyond a reasonable doubt.

What You Need to Know About Felony DWI in Franklin County, MO

A felony DWI charge in the Franklin 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.

This guide explains important aspects of felony DWI cases in Franklin County, MO, including:

  • What can elevate a Missouri DWI to a felony, 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
  • What penalties may follow a felony DWI conviction, including felony classifications, prison exposure, and restrictions on probation or parole
  • What happens when a DWI allegedly causes serious injury or death and why causation may become a critical issue in these cases
  • 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
  • What issues could potentially undermine the prosecution’s 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 and why both may require immediate attention following an arrest
  • How working with a felony DWI attorney in Franklin County, MO can affect your case investigate the allegations, challenge the state’s evidence, and fight to protect your freedom, record, and future

The consequences of a felony DWI conviction can continue long after the criminal case is resolved. The Franklin County, MO defense attorneys at Combs Waterkotte can investigate the evidence, examine how the state is attempting to establish felony DWI charges, and build a defense around the circumstances of your case.




When Does a DWI Become a Felony in Franklin County, MO?

Missouri does not treat every DWI offense the same. A person facing a first DWI in Franklin 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.

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 Franklin County, MO include:

  • High Blood Alcohol Concentration (BAC): A BAC level of .15 or higher increases penalties and restricts alternative sentencing options.
  • Repeat Offender Status: Multiple previous intoxication-related traffic offenses can result in repeat-offender classifications and potentially elevate a new DWI to a felony.
  • Injury or Death: When prosecutors allege that criminally negligent intoxicated driving caused another person’s injury or death, the defendant can face substantially enhanced criminal exposure.
  • A Child 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.
  • Other Factors: Driving with a suspended or revoked license or refusing a chemical test can compound the severity of the charges.

A felony DWI case can involve two separate battles. Your Franklin County, MO DUI defense attorney may need to challenge the allegation that you were intoxicated while also examining whether prosecutors can legally establish the prior convictions or aggravating circumstances necessary to elevate the charge.

Repeat DWI Offender Classifications in Franklin County, MO

Prior DWI-related offenses can transform the way a new impaired driving case is prosecuted in Missouri. As qualifying offenses accumulate, or when a defendant’s record includes certain more serious intoxication-related offenses, the potential charges and penalties can increase considerably. RSMo § 577.023 establishes several repeat-offender classifications that can affect a DWI prosecution:

Persistent Offender in Franklin County, MO

A defendant may be classified as a persistent offender when qualifying prior intoxication-related traffic offenses satisfy Missouri’s statutory requirements. This classification can elevate a DWI to a felony and expose the defendant to penalties considerably more serious than those associated with a misdemeanor conviction.

Aggravated Offender

A more extensive or serious history of qualifying DWI-related offenses can lead to aggravated offender status. This classification carries greater criminal exposure than persistent offender status, including the possibility of a more serious felony conviction and a longer period of incarceration.

Chronic Offender in Franklin County, MO

Missouri law also recognizes chronic offenders, who face even greater criminal exposure based on their history of qualifying DWI-related offenses. At this level, prosecutors may seek substantial prison time, making careful examination of every prior conviction critical to the defense.

Franklin County, MO Habitual Offender

Habitual offender status is reserved for some of the most serious repeat DWI cases prosecuted in Franklin 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 Franklin 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

The potential punishment for DWI in Missouri can change dramatically based on a defendant’s prior intoxication-related traffic history. While prior offender status generally remains a misdemeanor, qualifying as a persistent offender in Franklin County, MO can result in felony prosecution. From there, aggravated, chronic, and habitual offender classifications carry increasingly serious felony designations and potential terms of imprisonment.

Offender Classification Qualifying Offense History DWI Classification Potential Prison Sentence 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

Keep in mind: 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 impact of a felony DWI conviction in Franklin County, MO may extend far beyond incarceration. A felony record can create barriers involving employment, professional licensing, housing, education, immigration consequences, and firearm rights. Another DWI allegation in the future may also carry significantly greater criminal exposure because of the prior conviction.

That is why hiring a skilled Franklin County, MO DWI defense attorney should begin as early as possible.


Felony DWI Involving Serious Physical Injury in Franklin County, MO

A DWI case in Franklin County, MO can carry much greater consequences when the state claims that intoxicated driving resulted in serious physical injury to another person. These allegations can arise from crashes involving:

  • Other drivers
  • Passengers
  • Pedestrians
  • A cyclist
  • Motorcyclists
  • An emergency responder
  • Road construction workers
  • Other individuals injured at or near the accident scene

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 Franklin 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.

Even in a fatal accident case, however, the government must prove its allegations. A comprehensive defense investigation may consider evidence such as:

  • How and why the collision occurred
  • Vehicle speeds before impact
  • Braking and steering inputs
  • Traffic control devices
  • Weather and roadway conditions
  • Surveillance or dash-camera footage
  • Vehicle impact patterns and physical damage
  • Event data recorder information
  • Eyewitness accounts
  • Blood, breath, or other toxicology evidence
  • Accident reconstruction reports
  • Whether another motorist’s actions contributed to the fatal collision

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 Franklin County, MO can work with investigators and expert witnesses to independently examine the collision and challenge weaknesses in the government’s accident reconstruction.

What Evidence Do Prosecutors Use in Felony DWI Cases in Franklin County, MO?

Felony DWI prosecutions may involve considerably more evidence than an ordinary traffic stop. Police and prosecutors may rely on:

  • Observations made by responding officers
  • Dash-cam video
  • Body-camera footage
  • Field sobriety testing
  • Breathalyzer test results
  • Blood and urine analysis
  • Hospital records
  • Eyewitness accounts
  • 911 calls and dispatch recordings
  • Surveillance video
  • Vehicle data
  • Cellphone data and records
  • Accident reconstruction reports
  • Prior DWI records

The existence of this evidence does not necessarily mean that it is accurate, reliable, or sufficient to prove a felony DWI charge.

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.

Challenging Breath and Blood Tests in a Franklin County, MO Felony DWI Case

A BAC result may be powerful evidence for prosecutors, but it is not necessarily unquestionable. Breath-testing devices must be properly maintained and operated. Blood samples must be properly collected, preserved, transported, tested, and documented. Errors anywhere in that process can raise questions about reliability.

Issues that may warrant further investigation include:

In a serious accident case, chemical evidence may originate from blood drawn during emergency medical treatment rather than a routine DWI investigation. An experienced Franklin County, MO felony DWI lawyer can investigate the circumstances surrounding the blood draw, trace the handling of the sample, examine the testing methodology, and determine whether there are grounds to challenge the reliability or admissibility of the prosecution’s chemical evidence.

Facing a felony DWI charge in Franklin County, MO? When you select Combs Waterkotte a felony DWI lawyer in or around Franklin County, MO, you aren’t only selecting a leading felony DWI defense attorney in Franklin County, MO and beyond – you are protecting your rights, your freedom, and your future. Along with knowledgeable felony DWI defense attorneys, our legal team is available 24/7 and offers expertise in the following areas for Franklin County, MO residents:

How Can You Fight Felony DWI Charges in Franklin 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:

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 Franklin 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.

Breath or Blood Evidence Cannot Be Trusted

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

Police may interpret slurred speech, poor balance, confusion, red eyes, or unusual behavior as evidence of intoxication. Yet fatigue, stress, medical conditions, injuries, medications, and other circumstances may produce similar observations.

Body-camera and dash-camera footage can sometimes tell a very different story than the language used in a police report.

Disputing What Caused the Accident or Injuries

In felony cases involving an accident, prosecutors may need to prove more than intoxication. They may also need to establish the relationship between the defendant’s conduct and the resulting injury or death.

Evidence involving vehicle speeds, road conditions, mechanical failures, traffic signals, another driver’s actions, or accident reconstruction may raise questions about whether the defendant actually caused the collision or resulting injuries.

Prior Convictions Do Not Support the Enhancement

When prosecutors rely on previous intoxication-related traffic offenses to turn a DWI into a felony or increase its classification, the underlying records should be carefully reviewed.

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 Should You Do After a Felony DWI Arrest in Franklin County, MO?

What you do following a felony DWI arrest can have consequences for both the criminal prosecution and your driving privileges. If you have been arrested for felony DWI in or around Franklin County, MO, consider taking the following steps:

Step 1: Do Not Discuss the Facts of Your Case With Investigators Without Legal Counsel

You are not required to help investigators build the criminal case against you. Police may ask additional questions about where you were, what you consumed, or how an accident occurred. Use your right to remain silent and consult your Franklin County, MO felony DWI defense attorney before providing statements about the allegations.

Step 2: Do Not Post About the Arrest or Accident on 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

Keep photographs, videos, text messages, receipts, rideshare information, location records, and other materials connected to the events before or after your arrest. Your attorney may be able to use this information to establish a timeline, locate witnesses, or challenge portions of the prosecution’s account.

Step 4: Organize Your Court and Driver’s License Documents

Keep every document you receive from law enforcement, the court, or Missouri driver’s license authorities. Your criminal prosecution and administrative driver’s license proceedings are separate matters, and each may involve its own requirements and deadlines.

Step 5: Begin Building Your Defense as Soon as Possible in Franklin County, MO

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 Franklin 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.
