The DWI Law in Missouri
Drunk driving is charged as DWI in Missouri, at a blood alcohol level of 0.08 or more.
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.
