Sitting in the back of a patrol car and wondering how a DWI charge could affect your future is enough to make anyone’s head spin. Most first-time DWI charges in Missouri are misdemeanors rather than felonies, but “misdemeanor” does not mean “minor.” A conviction can still affect your driving privileges, criminal record, employment opportunities, and future plans.
If you are facing a DWI charge, you need a defense team that knows how to examine the police report, chemical-testing records, and field sobriety testing for issues that may affect your case.
KC DUI & Defense Counsel represents people facing DWI and other criminal charges throughout the Kansas City area. Call us today at (816) 287-3787 for a free consultation.
Is a DWI a Misdemeanor in Missouri?
Yes, generally. Under Missouri law, most first-time driving while intoxicated charges are classified as misdemeanors, though the specific classification and potential penalties depend on the circumstances of the arrest and the driver's criminal history.
Missouri DWI Laws in Missouri
Missouri's DWI statute, codified under RSMo § 577.010, defines the offense of driving while intoxicated and establishes the framework courts use to classify and penalize these charges.
Under Missouri law, a first DWI is generally a Class B misdemeanor. A person who qualifies as a statutory prior offender may face a Class A misdemeanor charge, while allegations involving additional prior offenses or certain injury-related circumstances can result in a felony charge.
When Is a Missouri DWI Charged as a Misdemeanor?
A Missouri DWI is often charged as a misdemeanor, but the charge level depends on the allegations and the person’s prior intoxication-related traffic convictions. A first DWI is generally a Class B misdemeanor. Under current Missouri law, a DWI can be charged as a Class A misdemeanor when the person is alleged and proved to be a prior offender or when a person younger than 17 was in the vehicle.
Penalties for a Misdemeanor DUI Conviction
A misdemeanor DWI conviction can still have significant consequences. The possible sentence depends on the charge classification, criminal history, BAC evidence, and other circumstances of the case. Potential penalties may include:
- First-offense DWI: A first DWI is generally a Class B misdemeanor, punishable by up to six months in jail and a fine of up to $1,000. If the court grants a suspended imposition of sentence, Missouri law generally requires a minimum two-year probation term for a first DWI.
- DWI involving a prior offender: A DWI charged against a statutory prior offender is generally a Class A misdemeanor, which may carry up to one year in jail and a fine of up to $2,000. Before probation or parole is granted, the person generally must serve at least 10 days in jail, complete 30 days of qualifying community service, or satisfy applicable court-ordered treatment and community-service requirements.
- Higher BAC sentencing rules: If a person is convicted of a first DWI and the court does not grant a suspended imposition of sentence, a BAC from 0.15% to 0.20% can require at least 48 hours in jail. A BAC above 0.20% can require at least five days in jail.
- License consequences: Missouri Department of Revenue proceedings are separate from the criminal case. An arrest involving a BAC at or above the legal limit or a chemical-test refusal can lead to an administrative suspension or revocation, even if the criminal ticket is later reduced or resolved in court. Refusing a requested chemical test can result in a one-year revocation of driving privileges.
- Restoring driving privileges: Depending on the case and driving history, a person seeking reinstatement may need to complete Substance Awareness Traffic Offender Program (SATOP), provide proof of insurance, pay reinstatement fees, or comply with ignition-interlock requirements.
Can a Misdemeanor DUI Be Reduced or Dismissed?
A reduction or dismissal may be possible in some Missouri DWI cases, but it is never automatic. The available options depend on the evidence, the applicable law, local prosecutorial practices, and the circumstances of the arrest.
In some cases, a prosecutor may agree to reduce a DWI charge to another traffic-related offense, often careless and imprudent driving. A prosecutor is not required to offer a reduction, and a plea to a lesser offense can still carry criminal, licensing, insurance, and employment consequences.
A dismissal or successful challenge may be possible where the evidence reveals a legal or factual problem, such as an unjustified stop, inadequate evidence of impairment, unreliable testing, or a failure to follow required procedures. KC DUI & Defense Counsel can evaluate the arrest, the officer’s reports, testing records, and available video to determine which issues may matter in your defense.
Defenses Used Against a Misdemeanor DUI Charge
Several defense strategies may apply depending on the specific facts of your case, including:
- Challenging the legality of the traffic stop: Police generally need reasonable suspicion of a traffic violation or criminal activity before initiating a traffic stop. If the stop was not legally justified, the defense may be able to challenge evidence obtained afterward.
- Questioning the administration or accuracy of field sobriety tests: These tests are highly subjective, and factors like uneven pavement, poor lighting, medical conditions, or an officer's own inexperience administering the test can all affect the reliability of the results.
- Disputing the reliability of breath or blood test results: Testing equipment requires regular calibration and proper administration procedures, and errors in either can call the accuracy of a result into serious question.
- Challenging the chain of custody or handling of physical evidence: Blood samples and other physical evidence must be properly collected, stored, and documented, and any break in that chain can raise legitimate doubts about the evidence's reliability.
The right strategy depends heavily on the specific evidence in your case, which is why a thorough review of your arrest and the surrounding circumstances is essential from the outset. Even when the prosecution believes its case is strong, a detailed review may identify legal or factual issues that affect how the case should be defended or resolved.
