West Virginia commercial vehicle weight limits follow the federal Interstate standard of 80,000 lbs gross, 20,000 lbs per single axle, and 34,000 lbs per tandem axle group. The federal bridge formula (23 U.S.C. 127) applies on all routes. West Virginia imposes spring weight restrictions on secondary routes typically February through April. Mountain terrain makes spring restrictions critical for road preservation. Check WVDOT for current restricted routes before routing heavy loads on secondary roads during this period. Oversize and overweight permits are available from WV DOT for loads exceeding standard limits. Verify current road-specific postings with the West Virginia DOT before routing heavy loads.

Check current restrictions at WV DOT →The federal bridge formula limits the weight on any group of axles based on the distance between the outermost axles in the group. It applies in West Virginia on all routes where federal standards apply.
W = maximum weight in lbs · L = axle spacing in feet · N = number of axles
West Virginia DOT issues oversize/overweight permits through the WVDOT Permits Office. Apply online or by phone at transportation.wv.gov. Single-trip permits required for loads exceeding standard weight or dimension limits. Annual permits available for qualifying recurring heavy operations. Superloads require engineering review and route approval. West Virginia's mountainous terrain makes route planning critical for heavy moves — many roads have severe grade and curve restrictions.

Single axle limit is 20,000 lbs and tandem axle is 34,000 lbs. Secondary roads and bridges throughout West Virginia's mountainous terrain frequently have lower posted limits. Spring weight restrictions apply on secondary roads February through April. Overweight permits from WVDOT are required for loads exceeding standard limits.
Yes. West Virginia imposes spring weight restrictions on secondary routes typically from February through April. The state's mountainous terrain and older road infrastructure make spring restrictions critical. Interstate highways are generally not subject to spring restrictions, but secondary roads are frequently posted. Check WVDOT at transportation.wv.gov for current restricted routes before routing on secondary roads in late winter and spring.
Oilfield vehicles operating on public roads in West Virginia's Marcellus Shale areas (northern and eastern West Virginia) must comply with standard West Virginia weight limits. Produced water tankers and fracking equipment on public roads are subject to the same 80,000 lb Interstate and secondary road limits as other commercial vehicles. Vehicles operating on private lease roads off the public highway system are not subject to public road weight limits. Overweight permits from WVDOT are required for loads exceeding standard limits on public roads.
West Virginia oversize/overweight permits are issued by the WVDOT Permits Office. Apply online at transportation.wv.gov. Single-trip permits are required for loads exceeding standard weight or dimension limits. Annual permits are available for qualifying recurring heavy operations. West Virginia's mountainous terrain requires careful route planning for all heavy moves — many secondary roads have grade and curve restrictions that make them impassable for heavy or oversized loads regardless of permit status.
Yes, and this is a significant concern in West Virginia. The state has a large inventory of older secondary road bridges with individually posted weight limits significantly below state maximums. This is especially important in rural areas, coal country in southern West Virginia, and oilfield access roads in the north. Always verify bridge weight postings on your planned route. Contact WVDOT for route-specific bridge weight information before dispatching heavy loads on non-Interstate routes.
