Road Reporting

Condition Reporting Frequency

The winter reporting season is November through April and conditions during those months are updated twice a day or as major changes occur. However, weather and highway conditions in Montana change quickly, and the reports are not real time.

During the non-reporting season motorists are cautioned to be aware of changing conditions and should expect normal Montana seasonal driving conditions.

Road reports are based on the last known and reported condition. Travelers should be aware that dry or wet and bare conditions may not be reported during the non-winter months. In the event of winter storm activity during the non-reporting season, conditions other than wet or dry, such as slush or snowcover, will be reported.

Please refer to our camera and RWIS page for more additional condition information.

Please see our Winter Maintenance page for road condition descriptions.
