The Montana 511 mobile application provides real-time access to traffic and traveler information supplied by the Montana Department of Transportation (Montana DOT). Maps depict current traffic conditions, as well as incident and construction events that can impact traffic on all Interstate, U.S., and State Routes. Alert, and weather information is also available. The map indicates the location of roadside cameras, which allow users to view current traffic conditions. As users move through the highway network, the app can keep track of their location on the map. Montana DOT's Twitter feeds are also accessible and provide information impacting traffic across the state's regions.

Junkies love

Alot of information and high learning curve. Wasteful and not a quick look while driving. So complicated that is close to worthless. Older system was better. Nice if you’re just catering to out of state people.
