The state of Montana doesn’t tolerate drugged or drunk driving. Montana overhauled its DUI laws in 2021 to make them tougher. If you’re convicted of driving under the influence (DUI), you face jail time, hefty fines, and lengthy license suspensions. Montana couples its penalties with a substance abuse treatment program and required education courses to reduce repeat DUI offenses.<\/p>\r\n

Montana decriminalized the possession of small amounts of cannabis in 2021. Montana amended its DUI law to recognize a legal limit for cannabis intoxication.<\/p>\r\n

Driving with any level of impairment is dangerous. In 2020, 66% of traffic fatalities in Montana<\/a> involved an impaired driver. Montana’s law enforcement officers receive specialized training to look for impaired drivers.<\/p>\r\n
