The Winter Travel Advisory operates from early December through March 30th. It is updated twice a day or as information concerning travel conditions is received. If you need more current or specific information, please listen to your local radio or television stations. You may also call the Michigan State Police Winter Travel Advisory Hotline at 1-800-381-8477.
Conditions are listed for freeways and state trunk lines. These roadways are the first to be cleared during inclement winter weather. It is unusual for conditions on rural and county roads to be better than those listed in this advisory. While drivers are encouraged to use all available information when making winter travel plans, even the latest, most accurate information is not a substitute for good judgment. If weather conditions appear to be too severe to travel, they most likely are.
