No vehicle which is designed or used for the purpose of hauling logs, poles, lumber, barrels, hogsheads, or other materials or containers which by their nature may shift or roll, shall be operated or moved on any highway unless its load is securely fastened by adequate log chains, metal cables, nylon webbing, steel straps or other restraining devices so as to prevent the load from shifting or falling from the vehicle. Tobacco hogsheads may, however, be secured by manila or hemp rope, at least five-eighths inch in diameter, of sufficient strength securely to fasten the hogshead against shifting, falling, or rolling. Nothing in this section shall release the owner or operator from liability for failure to use reasonable care to prevent the load from shifting or falling.
