The commission shall attach to the permit, at the time of issuance, and from time to time thereafter, such reasonable terms, conditions, and limitations consistent with the character of the holder as a contract carrier as are necessary to carry out, with respect to the operations of such a carrier, the requirements established by the commission under this subchapter.
(b)
(1) The commission shall not issue any permit which will authorize any contract carrier to have in effect, at any one time, more than six (6) contracts, such contracts to be filed with and approved by the commission prior to granting of such authority.
(2) When any contract expires, the commission shall be given notice thereof, and if any new contract is substituted or added, the contract shall be filed with and approved by the commission before operation thereunder.
(c) No permit issued under this subchapter shall confer any proprietary or property rights in the use of public highways.
