Sec. 21. (a) In the exercise of its power to prescribe just and reasonable rates, fares, and charges for the transportation of passengers or household goods by common carriers by motor vehicle, and related classifications, regulations, and practices, the department shall give due consideration, among other factors, to:

(1) the inherent advantages of transportation by those carriers;

(2) the effect of rates upon the movement of traffic by the carrier or carriers for which the rates are prescribed;

(3) the need, in the public interest, of adequate and efficient transportation service by such carriers at the lowest cost consistent with the furnishing of service; and

(4) the need of revenues sufficient to enable such carriers under honest, economical, and efficient management to provide service.

     (b) In determining the reasonableness of fares, rates, and charges of motor carriers of passengers or household goods, the department shall determine that the revenue is sufficient to cover the cost (including all operating expenses, depreciation accruals, rents, and taxes of every kind) of providing adequate transportation service and reasonable profit to the carrier. The relation of carrier expenses to carrier revenues may be considered the proper test of a reasonable profit.
