duty of every common carrier of passengers to establish, observe and
enforce just and reasonable rates, fares and charges, and just and
reasonable regulations and practices relating thereto.

2. Common carriers of passengers by motor vehicle may establish
through routes and joint rates, fares and charges with other such
carriers and once established it shall be the duty of all such carrier
parties to establish just and reasonable rates, fares, charges,
regulations and practices and equitable divisions of revenue.

3. All such charges made for any service rendered, or to be rendered
by any common carrier of passengers by motor vehicle, shall be just and
reasonable, and every unjust and unreasonable charge for such service or
any part thereof, is prohibited and declared to be unlawful. It shall be
unlawful for any common carrier to make, give or cause any undue or
unreasonable preference or advantage to any particular person or to
subject any particular person to any unjust discrimination or any undue
or unreasonable prejudice or disadvantage in any respect whatsoever.

4. Whenever, after a hearing, upon complaint, or in an investigation
on the commissioner's own initiative, the commissioner shall determine
that any individual or joint rate, fare or charge in effect or proposed
to be put into effect by any common carrier or group of common carriers
of passengers by motor vehicle or any rule, regulation or practice
whatsoever affecting such rate, fare or charge or the value of the
service thereunder, is or will be unjust or unreasonable, or unjustly
discriminatory, unduly preferential or unduly prejudicial, the
commissioner shall determine and prescribe the lawful rate, fare or
charge, or the lawful rule, regulation or practice thereafter to be
observed.

5. The commissioner shall, whenever deemed necessary or desirable in
the public interest, after a hearing, upon complaint or upon the
commissioner's own initiative, establish through routes and joint rates,
fares, charges, regulations or practices, applicable to the
transportation of passengers by common carriers and the terms and
conditions under which such through routes shall be operated.

6. Whenever, after a hearing, upon complaint or upon the
commissioner's own initiative, the commissioner shall determine that the
divisions of joint rates, fares or charges applicable to the
transportation of passengers by common carriers are or will be unjust,
unreasonable, inequitable, or unduly preferential or prejudicial as
between the carrier parties, the commissioner shall by order prescribe
the just, reasonable and equitable divisions thereof. The order of the
commissioner may require the adjustment of divisions between the
carriers, in accordance with the order, from the date of filing the
complaint or entry of order of investigation, or such other date
subsequent as the commissioner finds justified and, in the case of joint
rates or fares prescribed by the commissioner, the order as to divisions
may be made effective as a part of the original order.

7. In proceedings to determine the reasonableness of rate or fare
levels for a common carrier of passengers or group of common carriers of
passengers, the commissioner shall authorize revenue levels that are
adequate under efficient management to cover total operating expenses,
plus a reasonable profit as determined by the commissioner.
