§24A-3-5. Undue preference prohibited.
Every contract carrier by motor vehicle is hereby forbidden
to give or cause any undue or unreasonable advantage or
preference to those whom it serves as compared with the patrons
of any common carrier by motor vehicle as that term is used in
this chapter, or the patrons of any other common carrier, or to
subject the patrons of any such common carriers to any undue or
unreasonable discrimination or disadvantage; or by unfair
competition to destroy or impair the service or business of any
common carrier by motor vehicle, or of any other common carrier,
or the integrity of the state's regulation of any such service or
business; and, to the end that the said commission may enforce
these provisions, each such contract carrier by motor vehicle
shall maintain on file with the commission a statement of its
charges, and of such other matters as the commission may require.
