West Virginia Frost Laws & Spring Thaw Limits

West Virginia mountains and all, the state runs no declared spring thaw program. WV DOH posts no statewide frost-zone order and cuts no fixed percentage. But the state classifies its roads, and enforcement will ticket you for ignoring a posted weight sign, often 10 ton, on a soft secondary road in spring. The roadside sign is the limit, not the map. Interstates stay at full 80,000. Confirm any current posting with the WV Division of Highways before you haul a back route.
