Missouri Aggravated DWI Lawyer

Felony DWI Defense Across Missouri | Attorney Andrew Brumitt

A fourth-offense DWI (Driving While Intoxicated) or DUI (Driving Under the Influence) in Missouri is a serious felony offense under RSMo § 577.010 and § 577.023.
At this stage, the State classifies you as an Aggravated Offender, meaning prosecutors will seek felony-level punishment, mandatory jail time, and long-term loss of your driver’s license.

If you’re facing an aggravated DWI charge, you need a lawyer who doesn’t flinch at tough cases.
At Brumitt Legal, attorney Andrew Brumitt personally handles your defense from start to finish—no associates, no case managers, and no handoffs. You’ll work directly with a trial attorney who knows how to fight the government’s case, challenge the evidence, and protect your future.

What Is an Aggravated DWI in Missouri?

Under RSMo § 577.023, you are considered an Aggravated DWI Offender if you have been found guilty of or pleaded guilty to three or more prior DWI or BAC offenses.
A fourth DWI is typically charged as a Class D Felony, which carries significantly harsher penalties than prior offenses.

Consequences of an Aggravated DWI in Missouri

Conviction for an aggravated DWI brings severe, mandatory consequences, including:

  • Up to 7 years in prison

  • Mandatory minimum of 60 days in jail (which cannot be suspended or probated unless the court requires the jail term or equivalent community service)

  • Fines up to $10,000

  • 10-year denial of driving privileges through the Missouri Department of Revenue

  • Mandatory installation of an Ignition Interlock Device (IID) before any reinstatement or limited driving privileges

  • Mandatory completion of SATOP (Substance Abuse Traffic Offender Program)

  • Permanent felony criminal record

  • Loss of professional licenses and firearm ownership rights

  • Severe increases in auto insurance premiums and SR-22 filing requirements

  • Employment and housing barriers due to the felony conviction

If the case involves a BAC of 0.15% or higher, an accident causing injury, or a child in the vehicle, the prosecution can seek sentence enhancements, including additional jail time, community service, or higher fines.

How Attorney Andrew Brumitt Defends Felony DWI Charges

A fourth DWI case is complex—and the State often overreaches by including prior convictions that can’t legally be used for enhancement.
Attorney Andrew Brumitt carefully reviews every piece of evidence and every prior conviction to identify weaknesses in the State’s case.

He investigates:

  • Whether each prior DWI conviction was constitutionally valid and admissible for enhancement

  • The legality of the initial stop and arrest (was there probable cause?)

  • How field sobriety tests were administered and whether officers followed NHTSA standards

  • Breathalyzer or blood test accuracy, calibration, and maintenance records

  • Chain of custody and laboratory handling errors

  • Body-cam or dash-cam footage that contradicts the police report

  • Violations of Miranda or due process rights

Andrew’s strategy focuses on suppressing unlawfully obtained evidence, reducing enhancement levels, and pursuing alternative sentencing options that emphasize rehabilitation over incarceration.

Driver’s License Consequences for Aggravated DWI in Missouri

An aggravated DWI triggers both criminal penalties and administrative sanctions from the Missouri Department of Revenue (DOR).

Administrative Consequences

  • Ten-year license denial under § 302.060(9) RSMo

  • Reinstatement only after satisfying strict requirements:

    • Completion of SATOP and all treatment recommendations

    • Proof of SR-22 insurance

    • Installation of an Ignition Interlock Device (IID)

    • Payment of reinstatement fees and DOR approval

Criminal Case Consequences

In addition to administrative penalties, the court may impose prison time, probation, and extensive post-release supervision.
Courts often require continuous alcohol monitoring, counseling, and full compliance with sobriety conditions during probation.
