Missouri uses the term DWI for drunk driving offenses, rather than the more common DUI.
Missouri is a bit of a tricky state for the Fair DUI flyer, if you’re getting a ticket. For traffic stops and checkpoints you only have to display or exhibit your license, which you can do through a closed window. The state Supreme Court ruled failure to show your license is not a crime, but we still recommend that you show it.
The tough issue in Missouri is whether you have to sign a ticket. We can’t find any statute or court rule that requires you to sign. However, the court’s form for tickets includes a spot to sign.
We recommend that you don’t sign unless the officer orders you to sign (see our video on the difference between an order and a request). If the officer insists we recommend that you digitally sign the ticket using an app like SignEasy.
Here is our flyer in pdf format, and below that is a state bar opinion on checkpoints.
