W. Va. Code § 17A-3-11
The commissioner, upon registering any truck, truck tractor or road tractor, under the laws of this state, may require such information and may make such investigation or test as necessary to determine whether such motor vehicle may safely be operated upon the highways in compliance with all the provisions of law relating to such vehicles. Every such vehicle shall be registered with a permissible gross weight under which the vehicle can safely be operated upon the highways, which weight may not exceed the limitations set forth in chapter seventeen-c of this code.
The commissioner shall include on the registration card issued for every such motor vehicle the gross weight for which it is registered, and if it is a motor vehicle to be used for propelling other vehicles, a separate listing of the total permissible gross weight of such motor vehicle and other vehicles to be propelled by it shall be included. The commissioner shall also cause to be printed or stamped upon the registration card a statement that the vehicle although registered for the gross weight appearing on the registration card is subject to the axle load limit set forth in chapter seventeen-c of this code.
