What is a Felony DWI?
Driving While Intoxicated (DWI) in Missouri becomes a felony when certain aggravating circumstances are present. While most first and second DWI offenses are misdemeanors, a DWI can be charged as a felony under Missouri law in cases involving repeat offenses, injuries, death, or other serious factors.
A felony DWI is not just a more serious classification—it carries the possibility of extended prison time, heavy fines, license revocation, and long-term damage to your record and reputation. Missouri categorizes felony DWIs into various "persistent," "aggravated," and "chronic" offender statuses, each carrying heightened penalties.
Understanding whether your DWI qualifies as a felony—and what level—is critical to building your defense. That’s where an experienced St. Louis felony DWI attorney from JMH Law Firm, LLC comes in.
Common Types of Felony DWI in Missouri
There are several ways a DWI can rise to the level of a felony in Missouri. Below are the most common types:
Third or Subsequent DWI Offense
If you have two or more prior DWI or related alcohol/drug driving offenses, your next DWI will likely be charged as a felony. Missouri law labels repeat offenders as:
- Persistent Offender (third offense) – Class E felony
- Aggravated Offender (fourth offense) – Class D felony
- Chronic Offender (fifth offense) – Class C felony
- Habitual Offender (five+ prior intoxication-related traffic offenses) – Class B felony
DWI Causing Injury or Death
If a person is injured or killed as a result of drunk driving, the DWI becomes a felony under different classifications:
- DWI Resulting in Physical Injury – Class D felony
- DWI Resulting in Serious Physical Injury – Class C felony
- DWI Resulting in Death – Class B or Class A felony depending on circumstances
DWI with a Minor in the Vehicle
Driving while intoxicated with a passenger under the age of 17 can elevate the charge to a felony, especially if the child is injured.
DWI While Driving with a Suspended or Revoked License
If your license was already suspended due to a prior DWI and you're caught driving intoxicated again, you may face felony charges.
Penalties for Felony DWI
Felony DWI penalties in Missouri are far more severe than misdemeanor cases. Below is a general breakdown by felony level:
Class E Felony (Persistent Offender):
- Up to 4 years in prison
- Fines up to $10,000
- License revocation for 5 years
Class D Felony (Aggravated Offender):
- Up to 7 years in prison
- Extended probation terms
- 10-year license denial
Class C Felony (Chronic Offender or Injury DWI):
- 3–10 years in prison
- 10-year license revocation
- Mandatory alcohol treatment
Class B Felony (Habitual Offender or DWI Causing Death):
- 5–15 years in prison
- Permanent license revocation
- Possible denial of probation or parole
Class A Felony (Multiple Deaths or Extreme Negligence):
- 10–30 years or life imprisonment
- No probation eligibility
Additional penalties can include mandatory installation of an ignition interlock device, substance abuse evaluation, community service, and more.
The severity of these punishments highlights why securing qualified legal representation is essential. At JMH Law Firm, LLC, our St. Louis felony DWI lawyers fight to reduce or dismiss charges whenever possible and protect your future.
How a Felony DWI Charge is Proven in Missouri
To secure a felony DWI conviction, prosecutors must present evidence that proves the driver was intoxicated and that the offense meets Missouri’s felony criteria. These cases often rely on several types of evidence gathered during the investigation and arrest.
Common evidence used in felony DWI cases includes:
- Breathalyzer or blood test results showing a blood alcohol concentration (BAC) of 0.08% or higher.
- Field sobriety test performance, such as the walk-and-turn or one-leg stand tests.
- Police officer observations, including slurred speech, bloodshot eyes, and the smell of alcohol.
- Dashcam or body camera footage documenting the traffic stop and driver behavior.
- Witness statements from passengers, other drivers, or pedestrians.
- Prior DWI convictions, which prosecutors use to elevate the charge to a felony.
However, evidence is not always reliable. Breath testing equipment may malfunction, field sobriety tests can be administered incorrectly, and police officers can make procedural mistakes. Our team can review the evidence, identify weaknesses, and challenge unreliable testimony or testing methods.
Possible Legal Defenses to Felony DWI Charges
Just because you’ve been charged with a felony DWI does not mean a conviction is inevitable. Several legal defenses may apply depending on the circumstances surrounding your arrest and the evidence involved.
A strong defense strategy may include:
- Challenging the legality of the traffic stop if law enforcement lacked reasonable suspicion.
- Disputing chemical test accuracy due to faulty equipment or improper calibration.
- Questioning field sobriety test procedures, which are often subjective and influenced by weather, medical issues, or road conditions.
- Arguing lack of probable cause for the arrest if officers did not observe sufficient signs of impairment.
- Examining chain-of-custody issues with blood samples or other evidence.
- Highlighting constitutional violations, such as unlawful searches or failure to read Miranda rights.
Each case is unique, and the right defense can make a significant difference in the outcome. At JMH Law Firm, LLC, our attorneys carefully analyze every detail of your case to build the strongest possible defense against felony DWI charges in St. Louis.
Felony DWI FAQs
Can a felony DWI be reduced to a misdemeanor in Missouri?
It’s possible in some cases, particularly if there are flaws in the prosecution’s evidence or if the offense is on the borderline between classifications. An experienced defense attorney may negotiate a plea to a lesser offense, depending on the circumstances.
Will I lose my driver’s license after a felony DWI in Missouri?
Yes, felony DWI convictions typically result in long-term license revocation—often five or ten years. In some cases, you may be eligible for a limited driving privilege after a waiting period.
Is jail time mandatory for a felony DWI conviction?
For higher-level felony DWI charges—such as those involving injury, death, or multiple prior offenses—prison time is often mandatory. However, with the right defense strategy, alternative sentencing options like probation, treatment programs, or reduced charges may be possible.
Can I get a felony DWI expunged in Missouri?
Felony DWIs are generally not eligible for expungement in Missouri. Once convicted, it remains on your criminal record for life, impacting employment, housing, and other opportunities.
What if I refused a breath or blood test?
Refusing a chemical test can result in an automatic one-year license revocation under Missouri’s implied consent law. It can also be used against you in court. However, refusals don’t always mean a conviction—legal defenses are available.
