What Is Aggravated DUI in Montana and How Does It Affect a Missoula Case?
Aggravated DUI in Montana is a serious criminal charge carrying penalties well beyond a standard DUI. Montana law recognizes an "aggravated" DUI when certain factors are present, such as a blood alcohol concentration (BAC) of 0.16 or higher, a prior license suspension tied to a previous DUI, or refusing a breath or blood test when the person’s driver’s license was previously suspended, canceled, or revoked under the provisions of an implied consent statute. Originally codified under MCA § 61-8-465, Montana’s aggravated DUI provisions were repealed and recodified in 2021 under MCA §§ 61-8-1001, 61-8-1007, and related sections, effective January 1, 2022.
