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 Park County
The Park County Sheriff's Office and the agency that reports for Livingston make the DUI arrests in Park County.
Together, the two agencies in Park County with all twelve months of 2025 on file reported 204 arrests to the FBI that year, all offenses together; the FBI's count for Park County does not break DUI out.
Booking After a DUI Arrest in Park County
A driver arrested for DUI and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Park County Sheriff's Office, held about 19 people on an average day in 2019 by the Vera Institute of Justice's count and has a custody page SearchSystems verified at parkcountymt.gov/Government-Departments/Sheriff-s-Office/Inmates-Ho..., phone (406) 222-4100. The Park County inmate search guide covers the jail in full.
The Court Case
The case is heard in a Justice or Municipal Court, brought by the County Attorney or, in a municipal court, by the city's own prosecutor.
The court records page SearchSystems verified for the county is at parkcountymt.gov/Government-Departments/CLERK-OF-COURT, phone 406.222.4125.
Montana has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
The court case is only half the record. The Motor Vehicle Division runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Montana Motor Vehicle Division keeps the driving record the conviction goes on.
The Records a DUI Leaves
- The arrest report: from the agency that made the arrest, under the Montana Public Records Act.
- The court file: from a Justice or Municipal Court, kept by the Clerk of District Court.
- The driving record: from the Montana Motor Vehicle Division.
