(a)
The commission shall establish or approve just, reasonable, and nondiscriminatory maximum or minimum or maximum and minimum rates to be charged by household goods carriers for the transportation of used household goods and personal effects and for accessorial service performed in connection therewith.
(b)
In establishing or approving rates, the commission shall account for the cost of all transportation service performed or to be performed, for any accessorial service performed or to be performed in connection therewith, the value of the commodity transported, and the value of the equipment, facilities, and personnel reasonably necessary to perform the service.
(c)
The commission shall establish or approve no minimum rate for household goods carriers unless it finds that the rate is at a sufficient level to allow safe operation upon the highways of the state and accounts for the cost of trained drivers and other reasonable expense of operation of household goods carriers.
(d)
In establishing or approving any maximum rates for household goods carriers, the commission shall, on or immediately after January 1, 1996, adjust the current level of maximum rates by application and use of the index number methodology relied upon by the commission in 1992 to assist in the establishment of the current level of maximum rates and make that adjustment for the time period from the date that index was last relied upon to the latest date that index data is available. Thereafter, maximum rates shall be adjusted at least once annually by use of the same index methodology, or another index methodology found by the commission to be appropriate for the adjustment of household goods carrier maximum rates, less a reasonable percentage of any index increase to encourage higher productivity and promote efficiency and economy of operation by household goods carriers. The commission may also adjust maximum rates when deemed reasonable to allow for extraordinary changes in household goods carrier costs.
