The DWI Law in Missouri
In Missouri the offense is DWI, and the limit is 0.08.
Driving in Missouri is consent to a breath or blood test when an officer has cause to suspect DWI; the license case that follows a refusal or a failed test is run by the Department of Revenue, separately from the criminal case.
Who Makes DWI Arrests in Warrenton

Together, the three agencies in Warren County with all twelve months of 2024 on file reported 252 arrests to the FBI that year, all offenses together; the FBI's count for Warren County does not break DWI out.
