Red pickup driving past a white cross along a Montana highway Various locations on Montana’s roadways experience higher than typical crash and/or crash severity rates. In developing the Comprehensive Highway Safety Plan (CHSP), the Traffic and Safety Bureau (TSB) identified rural high crash severity corridors on the national and state road system in Montana. The purpose of this effort was to identify the State’s most significant high-crash corridors and to then conduct an analysis of crash data to identify the predominant factors contributing to crashes in these locations. This information was then used to support the identification of specific countermeasures that could be applied to these corridors.
