A DWI arrest in Missouri starts two cases against you at once: the criminal charge and the Department of Revenue action against your license. You have only a short window to request a hearing and protect your driving privileges — which is exactly why you should call Kielty Law the night of the arrest, not the week after.

Police traffic stop — DWI defense in Missouri

How Mike Fights a DWI

After 25 years of DWI trials, Mike knows exactly where these cases fall apart:

  • The stop. If the officer lacked reasonable suspicion to pull you over, everything that follows can be suppressed.
  • Field sobriety tests. These tests are subjective, frequently administered incorrectly, and challengeable.
  • The breath or blood test. Maintenance records, calibration logs, observation periods, and chain of custody are all attack points.
  • The refusal. Refusal cases carry their own license consequences — and their own defenses.

What's at Stake

A first-offense DWI is a class B misdemeanor, but penalties escalate fast: prior offenders, persistent offenders, aggravated and chronic offenders face felony charges, prison time, ignition interlock requirements, and long-term license revocation. Commercial drivers, professionals with licensure, and anyone who drives for work have even more on the line.

Don't Plead Until You Talk to Mike

Many people assume a DWI is unwinnable and plead guilty at the first court date. That's a mistake. Mike has taken DWI cases to trial and won — and prosecutors who know that fact negotiate differently with him than they do with attorneys who never try cases.
