Montana Requirements
Some offenders may be able to regain driving privileges if they install an ignition interlock device (IID) from an approved provider. This guide will explain the interlock process in Montana and how it works.
The MT Ignition Interlock Program
In Montana, the legal limit for drivers is below .08 percent BAC, and anyone found driving at or above the legal limit risks a variety of legal and administrative penalties. These include fines, license suspension, and possible jail time or community service. Montana allows some drivers to regain their driving privileges by installing an ignition interlock device, and requires an IID for repeat DUI offenders.What Happens if I Get a DUI in Montana?
