Last sentence of West Virginia Code § 17C-15-44-(d)-- (d) A person operating a motorcycle, motor-driven cycle or moped shall ride in a seated position facing forward and only upon a permanent operator's seat attached to the vehicle. No operator may carry any other person nor may any other person ride on the vehicle unless the vehicle is designed to carry more than one person, in which event a passenger may ride behind the operator upon the permanent operator's seat if it is designed for two persons, or upon another seat firmly attached to the vehicle to the rear of the operator's seat and equipped with footrests designed and located for use by the passenger or in a sidecar firmly attached to the vehicle. No person may ride side saddle on a seat. An operator may carry as many passengers as there are seats and footrests to accommodate those passengers. Additional passengers may be carried in a factory-produced sidecar provided that there is one passenger per seat. Passengers riding in a sidecar shall be restrained by safety belts.
