Mo. Rev. Stat. § 67.1816: City and county ordinances in effect until taxicab code adopted.

The city and county's ordinances relating to taxicabs shall remain in full force and effect and be enforced as such by the city and county until one hundred twenty days after the regional taxicab commission adopts its taxicab code, at which time such city and county ordinances shall be deemed to be rescinded as well as ordinances adopted by municipalities within the county. Upon the effective date of the taxicab code:

(1) All licensing, regulations, inspections, inspections of taxicabs, and enforcement of the taxicab code shall rest exclusively with the regional taxicab commission;

(2) All taxicabs subject to the taxicab code shall be required to comply fully with the taxicab code, notwithstanding any previously issued licenses or certificates of convenience;

(3) All permits valid and effective as of August 28, 2002, shall remain valid and effective until the date of expiration or renewal of such permit; and

(4) All available taxicab licensing, inspection, and related fees previously collected and remaining unspent by other jurisdictions shall be immediately paid over to* the regional taxicab commission for its future use in administering the taxicab code.

The provisions of this section notwithstanding, existing municipal regulations relating to taxicab curb locations and curb fees as well as local business licenses which do not seek to regulate taxicab use shall not be preempted by the taxicab code except by agreement between the commission and applicable municipality.
