There is an interesting article from an Aspen, Colorado newspaper about how DUI cases unfold in that jurisdiction. The system in Aspen is a lot different from what you could expect in a DUI or DWI case in Kansas or Missouri, but it does give a good overview of a DUI case from start to finish. Colorado DUI laws and Kansas DUI laws are different, and the court procedures are vastly different, but the scenario laid out in the article is similar to what one would find in a typical DUI charge in Kansas.
