The gross weight in the case of any motor truck, tractor, or truck tractor shall be the scale weight of the motor truck, tractor, or truck tractor, plus the scale weight of any trailer, semitrailer, converter gear, or pole trailer to be towed thereby, to which shall be added the weight of the maximum load to be carried thereon or towed thereby as set by the licensee in the application if it does not exceed the weight limitations prescribed by chapter 46.44 RCW. If the sum of the scale weight and maximum load of the trailer is not greater than four thousand pounds, that sum shall not be computed as part of the gross weight of any motor truck, tractor, or truck tractor. Where the trailer is a utility trailer, travel trailer, horse trailer, or boat trailer, for the personal use of the owner of the truck, tractor, or truck tractor, and not for sale or commercial purposes, the gross weight of such trailer and its load shall not be computed as part of the gross weight of any motor truck, tractor, or truck tractor. The weight of any camper is exempt from the determination of gross weight in the computation of any licensing fees required under RCW 46.16.070.

     The gross weight in the case of any bus, auto stage, or for hire vehicle, except taxicabs, with a seating capacity over six, shall be the scale weight of each bus, auto stage, and for hire vehicle plus the seating capacity, including the operator's seat, computed at one hundred and fifty pounds per seat.

     If the resultant gross weight, according to this section, is not listed in RCW 46.16.070, it shall be increased to the next higher gross weight so listed pursuant to chapter 46.44 RCW.
