DUI in Missouri
State-specific overview · Criminal Law
Missouri allows first-time DUI offenders to potentially avoid conviction through a suspended imposition of sentence if they meet conditions.
How Missouri treats DUI
Missouri permits first-time DUI offenders to receive a suspended imposition of sentence (SIS), meaning the conviction does not appear on their record if they complete probation and other requirements successfully. The state uses a 0.08% BAC threshold and imposes a minimum 48-hour jail sentence or 10 days of community service for a first offense. A second DUI within five years eliminates SIS eligibility and results in mandatory jail time and license suspension.
The general definition of DUI
Driving under the influence of alcohol or drugs, a serious criminal offense.
DUI stands for Driving Under the Influence and means operating a vehicle while impaired by alcohol, drugs, or both. You can be charged with DUI even if your blood alcohol level is below the legal limit if your driving is noticeably impaired. Penalties vary by jurisdiction and whether it's a first or repeat offense, but typically include fines, license suspension, jail time, and mandatory alcohol education programs. A DUI conviction has lasting effects on insurance rates, employment, and your driving record.
