The WVDOH established a snow and ice removal system based on the following priority groups:
First Priority Routes
Roads of major importance and high traffic volume are plowed and treated first and receive ongoing maintenance during winter events. These routes consist of all Interstates, major routes, and high traffic roadways connecting urban areas.
Second Priority Routes
Roads of just slightly less importance and traffic volume, such as school bus routes not included in First Priority routes. Second Priority routes are covered as conditions permit by the same equipment and personnel assigned to the maintenance of First Priority routes.
Third Priority Routes
Low traffic volume roads that receive attention only after all Second Priority routes have been covered.
