Missouri First-Offense DWI Lawyer

Defending Clients Across Missouri | Attorney Andrew Brumitt

A first-offense DWI (Driving While Intoxicated) or DUI (Driving Under the Influence of drugs) in Missouri is not a minor charge—it’s a criminal offense under RSMo § 577.010 that can affect your freedom, license, and future opportunities. Even one conviction creates a criminal record that follows you for years. If you’ve been charged, you need an experienced Missouri DWI lawyer who understands both the criminal and administrative sides of your case.

At Brumitt Legal, attorney Andrew Brumitt personally handles every DWI case from start to finish—no handoffs, no assistants managing your defense. You’ll work directly with a trial lawyer who knows how to challenge police reports, breath and blood tests, and the Department of Revenue’s attempt to suspend your license.

Consequences of a First-Offense DWI in Missouri (RSMo § 577.010)

Under Missouri law, a first DWI offense is typically charged as a Class B misdemeanor, punishable by:

  • Up to 6 months in jail

  • A fine of up to $1,000

  • A 90-day driver’s license suspension (30 days hard suspension, followed by 60 days restricted)

  • Mandatory participation in the Substance Abuse Traffic Offender Program (SATOP)

  • Possible ignition interlock device (IID) for limited driving privileges

  • Increased insurance rates or SR-22 filing requirements

  • Permanent criminal record that can affect background checks and employment

  • Professional license consequences for nurses, lawyers, teachers, and CDL drivers

  • Travel and reputation issues—especially for professionals, students, and public figures

If your blood alcohol concentration (BAC) was 0.15 % or higher, or if there was an accident, minor in the vehicle, or injury, penalties can increase significantly, and prosecutors may push for enhanced charges.

A first conviction also makes any future DWI arrest far more serious, potentially elevating it to a Class A misdemeanoror even a felony under Missouri’s persistent and aggravated offender statutes.

How Attorney Andrew Brumitt Fights First-Time DWI Charges

Attorney Andrew Brumitt takes a two-front approach: defending both your criminal case in court and your license suspension at the administrative hearing. Acting quickly can mean the difference between keeping your license and losing it.

Andrew investigates:

  • Whether the stop was lawful and supported by probable cause

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

  • Breathalyzer and blood-testing procedures, maintenance records, and chain of custody

  • Video or dash-cam footage that may contradict the police report

  • Medical conditions or environmental factors that could explain BAC or physical signs of intoxication

In many cases, Brumitt Legal can achieve dismissals, charge reductions, or diversion outcomes that keep your record clean and preserve your driving privileges.

First-Offense DWI License Suspension in Missouri

A first DWI arrest triggers two separate proceedings:

  1. Criminal Case — Filed in the local court based on the arrest.

  2. Administrative Suspension — Handled by the Missouri Department of Revenue (DOR).

If you do nothing, your license will be automatically suspended 15 days after your arrest. Andrew Brumitt immediately requests a hearing to challenge that suspension and fights to protect your driving rights.

If suspension does occur, he helps you obtain a Restricted Driving Privilege (RDP) so you can continue driving to work, school, or medical appointments.
