In the State of Missouri, there are two separate set of laws that apply to most Driving While Intoxicated (DWI) cases.

The first set of laws deal with the Criminal Consequences of your DWI arrest. The second set of laws deal with the effect that your DWI will have on your Missouri Driver’s License. These laws can be very complex as well as the vast amount of case law from the courts who have interpreted these laws.
