Indiana Code Title 8. Utilities and Transportation § 8-2.1-22-26

Sec. 26. (a) The department may require any contract motor carrier to file with it a true copy of any contract, agreement, or arrangement between the carrier and any person in relation to any traffic affected by this chapter.  The department shall not, however, make public the contract, agreement, or arrangement between a contract carrier by motor vehicle and a shipper, or any of the terms or conditions of the contract except as a part of the record in a formal proceeding where it considers that action consistent with the public interest.

(b) If it appears from an examination of the contract that it fails to conform to the published schedule of the contract carrier by motor vehicle as required by this chapter, the department may make public such of the provisions of the contract as the department considers necessary to disclose the failure and the extent of the failure.

(c) This section does not apply to contracts filed instead of schedules.
