The books and accounts of the Mississippi Department of Transportation shall be audited at the end of each fiscal year by the State Auditor. A copy of the audit shall be filed with the Governor, the Legislative Budget Office, and the Department of Finance and Administration and a copy kept on file in the Office of the Mississippi Transportation Commission. The audit shall be so segregated that it shall show in detail the expenditures of the Mississippi Department of Transportation for the period involved.

At a regular meeting in April of each year prior to the beginning of each July 1 fiscal year, the Mississippi Transportation Commission shall adopt a complete, detailed and itemized budget of each construction program, maintenance and administration based on information as required by the Legislative Budget Office, which budget shall not exceed a reasonably anticipated income of the commission for the succeeding fiscal year, and the essential features of such budget shall be spread at large on the minutes of the commission. A copy of the detailed budget shall be filed with the Governor and three (3) copies each with the Legislative Budget Office and the Department of Finance and Administration on or before May 30 of each year and shall cover all anticipated expenditures for construction, maintenance and all other expenditures for the ensuing fiscal year. The commission shall not make expenditures in excess of its published budget or any item thereof without written notice to the Legislative Budget Office and prior approval of the Department of Finance and Administration, except in case of extraordinary, unusual or unprecedented occurrences arising by reason of unforeseen events, floods, hurricanes or other acts of God or force majeure, in which event, upon the declaration of emergency and necessity spread at large upon the minutes, appropriate and necessary emergency expenditures may be made.
