Why it matters

Montana's vast, open landscapes and long stretches of highway can lull drivers into a false sense of security, but the data shows these roads can be extremely perilous. Raising awareness of the most dangerous routes is crucial for locals and visitors alike to stay safe while driving in Big Sky Country.

The details

According to the Reddit discussion, US Highway 93 between Missoula and Kalispell is one of the most dangerous roads in Montana, with wildlife and the Bitterroot Valley's winding terrain posing major risks. US Highway 191, especially the 'Gallatin Gauntlet' section between Bozeman and Big Sky, is also notoriously treacherous in winter due to solid ice, sharp curves, and high speeds. Interstate 90, which carries the highest number of daily drivers in the state, requires navigating several mountain passes, which can be extremely hazardous when covered in snow and ice.
