The DUI Law in Montana
In Montana the offense is DUI, and the limit is 0.08.
Driving in Montana is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the Motor Vehicle Division, separately from the criminal case.
Who Makes DUI Arrests in Billings

The Court Case
