In 2012, there were 476 severe injuries in Montana that were the result of motor vehicle drivers impaired by alcohol and/or drug impaired drivers. In 2012, 113 of the 205 motor vehicle crash fatalities in Montana were the result of an alcohol and or drug impaired driver. Montana’s alcohol-related fatality rate (the number of alcohol-related traffic fatalities per hundred million vehicle-miles traveled (VMT) in Montana) was 0.69 in 2011. From 2008-2012, alcohol/drug-related driving has contributed to 10% of all crashes, 19% of all injuries, and almost 46% of deaths on Montana’s roads.

Recognizing the severity of the problem in Montana, the following programs are in place to address impaired driving at the state and local levels, encompassing numerous education, enforcement, engineering, and treatment efforts.


  • Reduce the five-year average number of fatalities in crashes involving an alcohol-impaired driver or motorcycle operator (BAC 0.08+) from 90 in 2010 to 70 by 2015.
  • Reduce the five-year average number of fatalities and incapacitating injuries in crashes involving a driver or motorcycle operator with a BAC 0.01+ or evidence of alcohol and/or drugs being involved from 484 in 2010 to 375 by 2015.
