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.
[Ord. No. 783 §3, 3-18-1976; Ord. No. 1374 §1, 5-9-1996; Ord. No. 1563 §1, 9-13-2001]
No person shall operate or drive a motor vehicle (except emergency vehicles on emergency runs) on streets, boulevards or thoroughfares in the City, at any time, at a rate of speed in excess of twenty (20) miles per hour, unless a higher maximum rate of speed applicable to certain designated portions of specific streets be fixed by ordinance and marked by signs erected at the beginning and end of such designated portions of such streets, except on Woodson Road also designated as Highway EE and on Highway 115 (Natural Bridge), where the rate of speed shall not be in excess of forty (40) miles per hour; and on Interstate Highway I-70 throughout the City limits where the rate of speed shall not be in excess of sixty (60) miles per hour.
Any person convicted of or having pled guilty to speeding in excess of the specially posted speed limit or passing or overtaking a vehicle in a work or construction zone when there was any person present performing duties in the work or construction zone and appropriate signs were posted with the speed limit in such zone and stating: "Warning: $250.00 fine for speeding or passing in this work zone" shall be assessed a fine of two hundred fifty dollars ($250.00) in addition to any other fine assessed.
As used herein, the term "construction zone" or "work zone" means any area upon or around any highway as that term is defined in Section 302.010(b), RSMo., which is visibly marked as an area where construction, maintenance, or other work is temporarily occurring.
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.
