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.
[R.O. 1992 § 320.030; R.O. of 1942 § 622; CC 1970 § 13-27; Ord. No. 7230, 6-15-1992]
The City Traffic Engineer shall erect or cause to be erected at all places where the boundaries of the corporate limits of the City joins or crosses any highway, signs displaying in black letters not less than four (4) inches high and one (1) inch wide on a white background the City speed limits provided in Schedule I so that such signs may be clearly seen by operators and drivers from their vehicles upon entering the City.
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.
[R.O. 1992 § 320.040; Ord. No. 02-9203 §§ 1—4, 8-5-2002]
A. 
As used in this Section, the term "construction zone" or "work zone" means any area upon or around any highway, street or road which is visibly marked by the Missouri Department of Transportation, a contractor performing work for the Missouri Department of Transportation, the City of Washington, Missouri, Street Department, or a contractor performing work for the City of Washington, Missouri, as an area where construction, maintenance or other work is temporarily occurring. The term "work zone" or "construction zone" also includes the lanes of highway, street or road leading up to the area upon which an activity described in this Section is being performed, beginning at the point where appropriate signs directing motor vehicles to merge from one lane into another lane are posted.
B. 
Upon a conviction or plea of guilty by any person for a speeding violation, the court shall assess a fine of two hundred fifty dollars ($250.00) in addition to any other fine authorized by law if the offense occurred within a construction zone or a work zone and at the time the speeding or passing violation occurred, there was any person in such zone who was there to perform duties related to the reason for which the area was designated a construction zone or work zone. However, no person shall be assessed an additional fine pursuant to this Section if no signs have been posted pursuant to Subsection (D) of this Section.
C. 
The penalty authorized by Subsection (B) of this Section shall only be assessed by the court if the Missouri Department of Transportation, a contractor performing work for the Missouri Department of Transportation, the City of Washington, Missouri, Street Department or a contractor performing work for the City of Washington, Missouri, has erected signs upon or around a construction or work zone which are clearly visible from the highway, street or road and which state substantially the following message: "Warning: $250 fine for speeding or passing in this work zone."
D. 
During any day in which no person is present in a construction zone or work zone established pursuant to Subsection (B) of this Section to perform duties related to the purpose of the zone, the sign warning of additional penalties shall not be visible to motorists. During any period of two (2) hours or more in which no person is present in such zone on a day in which persons have been or will be present to perform duties related to the reason for which the area was designated as a construction zone or work zone, the sign warning of additional penalties shall not be visible to motorists. The Missouri Department of Transportation, any contractor performing work for the Missouri Department of Transportation, the City of Washington, Missouri, Street Department or any contractor performing work for the City of Washington, Missouri, shall be responsible for compliance with provisions of this Section. Nothing in this Section shall prohibit warning or traffic control signs necessary for public safety in the construction or work zone being visible to motorists at all times.
[R.O. 1992 § 320.050; Ord. No. 05-9812 § 1, 7-5-2005]
