1. All moneys received by a city imposing a sales tax pursuant to the provisions of sections 94.600 to 94.655 shall be deposited by the city treasurer, or other city officer authorized by ordinance, in a special fund to be known as the “Transportation Trust Fund”. All moneys in such transportation trust fund shall be appropriated and disbursed only for transportation purposes as enumerated herein.

2. Any portion or all of the funds on deposit in a transportation trust fund may be appropriated and paid by a city directly to an interstate transportation authority, a city transit authority or a city utilities board for its general purposes in providing a public mass transportation system within an interstate transportation district or a municipality; provided that, before such funds may be appropriated and paid to any such interstate transportation authority, city transit authority or city utilities board with a service area population in excess of two million persons, such authority or board shall develop, for mutual agreement, a program of transit service to be provided to the city. Such program shall define the service to be provided, the fare structure to be in effect, the estimated cost of the total transit service program of the authority or board, and the estimated cost of the city’s portion of the program. Such agreement shall be renewed prior to the beginning of each fiscal year and, when such agreement is reached, the city shall appropriate to the authority or board funds as are designated in the agreement for the period of the agreement. A city may designate by contract with an interstate transportation authority, a city transit authority or a city utilities board that a designated portion of such funds shall be used by the interstate transportation authority, the city transit authority or the city utilities board to provide specific service or frequency of service to underwrite a certain fare structure, or for any other purposes consistent with providing a sound public mass transportation system.

3. Any provisions of sections 94.600 to 94.655 to the contrary notwithstanding, not less than two percent of the proceeds of any sales tax imposed by any city not within a county and any county of the first class having a charter form of government and having a population of at least nine hundred thousand inhabitants pursuant to sections 94.600 to 94.655 that are appropriated and paid by a city or county to an interstate transportation authority shall be expended to sheltered workshop or residence facility, boards of directors established pursuant to section 205.970, to pay costs of transportation, above the level of expenditures for such costs during the fiscal year of the board immediately preceding January 1, 1984, to and from sheltered or presheltered employment of developmentally disabled clients of the regional center for the developmentally disabled serving the area where the tax is imposed, and shall be expended only for the purpose of transporting persons who are developmentally disabled and require nonpublic transportation and who are residents of the city not within a county, or of the adjacent county of the first class having a charter form of government and having a population of at least nine hundred thousand inhabitants. As used in this subsection, “developmentally disabled clients” means persons served by the regional center who have a developmental disability as defined in section 630.005.

4. No funds may be appropriated and paid to any such transportation authority, transit authority or utilities board, unless and until such authority or board shall file or shall have filed with the city, paying said funds, and the secretary of state of the state of Missouri, annually and within six months after the close of such authority or board’s fiscal year, an independently audited report and accounting as to such authority or board’s management and administration of any and all funds received and expended by such authority or board.

5. Transportation authorities operating a public mass transportation system pursuant to sections 94.600 to 94.655 shall provide for interior and exterior advertising on each vehicle for mass transportation purposes.
