In addition to any criminal charges for DUI/DWI, a state may assess civil (non-criminal) penalties against a person convicted of DUI/DWI. Civil penalties may include (1) thousands of dollars of fines; (2) suspension of the driver’s license; (3) requirements for additional insurance; (4) completion of alcohol rehabilitation/treatment and DUI/DWI intervention courses; and (5) installation of an ignition interlock device (IID) on the driver’s motor vehicle.

The laws regarding civil penalties for DUI/DWI convictions are generally located in a state’s statutes—often in the penal code or criminal code.

In Missouri, civil penalties for DUI/DWI convictions are indeed separate from criminal charges and can be quite severe. These penalties are outlined in the state's statutes, particularly in the areas concerning motor vehicles and traffic regulations. Upon conviction for DUI/DWI, the state may impose fines that can reach into the thousands of dollars. Additionally, the driver's license may be suspended or revoked, depending on the severity of the offense and prior convictions. Missouri law also requires individuals convicted of DUI/DWI to obtain SR-22 insurance, a type of high-risk auto insurance, which must be maintained for a period of time. Offenders may be mandated to complete alcohol education or rehabilitation programs, as well as DUI/DWI intervention courses. Furthermore, the installation of an ignition interlock device (IID) on the offender's vehicle is a common requirement, particularly for repeat offenders or those with high blood alcohol content (BAC) levels at the time of arrest. These civil penalties are designed to deter impaired driving and promote public safety on the roads.
