The State traffic laws regulating the speed of vehicles shall be applicable upon all streets within the City, except that the City may by ordinance declare and determine upon the basis of engineering and traffic investigation that certain speed regulations shall be applicable upon specified streets or in certain areas, in which event it shall be unlawful for any person to drive a vehicle at a speed in excess of any speed so declared when signs are in place giving notice thereof.
The City Traffic Engineer is authorized to regulate the timing of traffic signals so as to permit the movement of traffic in an orderly and safe manner at speeds slightly at variance from the speeds otherwise applicable within the district or at intersections and shall erect appropriate signs giving notice thereof.

A. 
This municipality, by ordinance, may by authority of Section 304.120, RSMo., establish reasonable speed regulations for motor vehicles within the limits of the municipality.
B. 
The maximum speed limit for vehicles operating within this municipality shall be twenty-five (25) miles per hour on all highways and streets unless otherwise posted. The maximum speed limit in any City park, driveway or on any alley shall be ten (10) miles per hour. This limit and other speed limits for specific areas as set out by current and future ordinances shall be listed in Schedule I Speed Limits of this Code and it shall be unlawful for any person to drive a vehicle in excess of specific speed limits for specific areas as set forth in the Schedule.
C. 
No person who is not a resident of this municipality and who has not been within the limits thereof for a continuous period of more than forty-eight (48) hours shall be convicted of a violation of this Section, unless it is shown by competent evidence that there was posted at the place where the boundary of the municipality joins or crosses any highway a sign displaying in black letters not less than four (4) inches high and one (1) inch wide on a white background the speed fixed by the municipality so that such sign may be clearly seen by operators and drivers from their vehicles upon entering the municipality.
No person shall drive a motor vehicle at such a slow speed as to impede or block the normal and reasonable movement of traffic, except when reduced speed is necessary for safe operation or in compliance with law. Peace Officers may enforce the provisions of this Section by directions to drivers, and in the event of apparent willful disobedience to this provision and refusal to comply with direction of an officer in accordance herewith, the continued slow operation by a driver is an ordinance violation.
No person shall operate a motor vehicle upon those portions of the roadways which are set forth and described in Schedule I at a rate of speed in excess of that speed limit set for such portions of the roadways by said Schedule.
