When charged with DWI in Missouri, there will be two forums in which defense or representation is required. They are distinct actions, yet interrelated. I will explain.
A DWI charge in Missouri requires a court case. That is where arraignments, preliminary hearings, various motions, plea bargaining, jury trials, sentencing, appeals, writs, etc., take place.
The Court, independent of the Department of Revenue (driver license), can set the conditions of release, probation, classes, suspensions, fines, penalties, jail time, diversions, etc.
