[Code 1975 §15.02(8); CC 1989 §13-266]
The City Traffic Engineer shall place and maintain traffic control signs, signals, and devices when and as required under the traffic ordinances of the City to make effective the provisions of said ordinances, and may place and maintain such additional traffic control devices as he/she may deem necessary to regulate traffic under the traffic ordinances of the City or under the State law or to guide or warn traffic.
[Code 1975 §15.02(5); CC 1989 §13-268]
All traffic control signs, signals and devices shall conform to the manual and specifications approved by the State Highways and Transportation Commission or ordinance adopted by the Board of Aldermen. All signs and signals required herein for a particular purpose shall so far as practicable be uniform as to type and location throughout the City. All traffic control devices so erected and not inconsistent with the provisions of this Chapter shall be official traffic control devices.
[Code 1975 §15.09(1); CC 1989 §13-271]
The driver of any vehicle shall obey instructions of any official traffic control device applicable thereto placed in accordance with this Title unless otherwise directed by a Police Officer, subject to the exceptions granted the driver of an emergency vehicle.
No provisions of this Title for which official traffic control devices are required shall be enforced against an alleged violator if at the time and place of the alleged violation an official device is not in proper position and sufficiently legible to be seen by an ordinarily observant person. Whenever a particular Section does not state that official traffic control devices are required, such Section shall be effective even though no devices are erected or in place.
[Code 1975 §15.09(14); CC 1989 §13-267]
Whenever official traffic control devices are placed in position approximately conforming to the requirements of this Title, such devices shall be presumed to have been so placed by the official direction or act of lawful authority, unless the contrary shall be established by competent evidence.
Any official traffic control device placed pursuant to the provisions of this Title and purporting to conform to the lawful requirements pertaining to such devices shall be presumed to comply with the requirements of this Title, unless the contrary shall be established by competent evidence.
[Code 1975 §15.09(2); CC 1989 §13-272]
Whenever traffic is controlled by traffic control signals exhibiting colored lights or colored lighted arrows, successively one (1) at a time, or in combination, only the colors green, yellow and red shall be used, except for special pedestrian control signals carrying a word legend, and such lights shall indicate and apply to drivers of vehicles and pedestrians as follows:
Vehicular traffic facing a circular green signal may proceed straight through or turn right or left unless a sign at such place prohibits either such turn. But vehicular traffic, including vehicles turning right or left, shall yield the right-of-way to other vehicles and to pedestrians lawfully within the intersection or an adjacent crosswalk at the time such signal is exhibited.
Vehicular traffic facing a green arrow signal, shown alone or in combination with another indication, may cautiously enter the intersection only to make the movement indicated by such arrow, or other movement as is permitted by other indications shown at the same time. Such vehicular traffic shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.
Steady yellow indication.
Vehicular traffic facing a steady yellow signal is thereby warned that the related green movement is being terminated or that a red indication will be exhibited immediately thereafter when vehicular traffic shall not enter the intersection.
Steady red indication.
Vehicular traffic facing a steady red signal alone shall stop before entering the crosswalk on the near side of the intersection or, if none, then before entering the intersection and shall remain standing until a green indication is shown except as provided in Paragraph (b) of this Subsection.
The driver of a vehicle which is stopped as close as practicable at the entrance to the crosswalk on the near side of the intersection or, if none, then at the entrance to the intersection in obedience to a red signal, may cautiously enter the intersection to make a right turn but shall yield the right-of-way to pedestrians and other traffic proceeding as directed by the signal at the intersection, except that the State Highways and Transportation Commission with reference to an intersection involving a State highway, and local authorities with reference to an intersection involving other highways under their jurisdiction, may prohibit any such right turn against a red signal at any intersection where safety conditions so require, such prohibition shall be effective when a sign is erected at such intersection giving notice thereof.
In the event an official traffic control signal is erected and maintained at a place other than an intersection, the provisions of this Section shall be applicable except as to those provisions which by their nature can have no application. Any stop required shall be made at a sign or marking on the pavement indicating where the stop shall be made, but in the absence of any such sign or marking the stop shall be made at the signal.
[Code 1975 §15.09(3); CC 1989 §13-273]
Whenever special pedestrian control signals exhibiting the word "Walk" or "Don't Walk" are in place such signals shall indicate as follows:
Walk. Pedestrians facing such signal may proceed across the roadway in the direction of the signal and shall be given the right-of-way by the drivers of all vehicles.
Wait or don't walk. No pedestrian shall start to cross the roadway in the direction of such signal, but any pedestrian who has partially completed his/her crossing on the walk signal shall proceed to a sidewalk or safety zone while the wait signal is showing.
[Code 1975 §15.09(4); CC 1989 §13-274]
Whenever an illuminated flashing red or yellow signal is used in a traffic sign or signal, it shall require obedience by vehicular traffic as follows:
Flashing red (stop signal). When a red lens is illuminated with rapid intermittent flashes, drivers of vehicles shall stop before entering the nearest crosswalk at an intersection or at a limit line when marked, or, if none, then before entering the intersection, and the right to proceed shall be subject to the rules applicable after making a stop at a stop sign; and
Flashing yellow (caution signal). When a yellow lens is illuminated with rapid intermittent flashes, drivers of vehicles may proceed through the intersection or past such signal with caution.
This Section shall not apply at railroad grade crossings. Conduct of drivers of vehicles approaching railroad grade crossings shall be governed by the rules as set forth in Section 300.295, RSMo.
[Code 1975 §15.09(6); CC 1989 §13-276]
It shall be unlawful for the operator of a vehicle traveling in a particular traffic lane on a roadway divided and marked into lanes to disobey a sign, signal, arrow or marker along the roadway which directs vehicles traveling in such lane to move in a particular lane or direction or not to move into a different lane or in a different direction.
[Code 1975 §15.09(12); CC 1989 §13-277]
No person shall place, maintain or display upon or in view of any highway an unauthorized sign, signal, marking or device which purports to be or is an imitation of or resembles an official traffic control device or railroad sign or signal, or which attempts to direct the movement of traffic, or which hides from view or interferes with the effectiveness of any official traffic control device or any railroad sign or signal.
[Code 1975 §15.09(13); CC 1989 §13-278]
No person shall, without lawful authority, attempt to, or in fact alter, deface, injure, knock down, or remove any official traffic control device or any railroad sign or signal or any inscription, shield or any insignia thereon or any other part thereof.
It shall be unlawful for any person to hide or obscure any official traffic control device, or signal by the erection of any object, or by allowing bushes, hedges, trees, or other vegetation to grow and obscure the same.
Unobstructed vision for traffic safety shall be maintained by the owner or occupant on all corner lots regardless of the zone classification with reference to any vehicle, trailer, sign, fence, ornament, hedge, shrub, tree, display, or any other obstruction, but not including buildings. No such obstruction to view between three (3) and eight (8) feet above the gutter line shall be placed or maintained within a triangular area at the street corner, which area is bounded by:
The street property lines of the corner lot and a line connecting points twenty-five (25) feet distant from the intersection of the property lines of such lot; or
The curb lines of an intersection and a line connecting points thirty-five (35) feet distant from the corner of the intersection and such corner is determined by projecting the curb lines out to a specified point, whichever is the lesser.
Every such object or vegetation is hereby declared a public nuisance and the authority having jurisdiction over the public way is hereby empowered to remove the same or cause same to be removed without notice.
The City Traffic Engineer is hereby authorized:
To designate and maintain, by appropriate devices, marks, or lines upon the surface of the roadway, crosswalks at intersections where in his/her opinion there is particular danger to pedestrians crossing the roadway, and at such other places as he/she may deem necessary; and
To establish safety zones of such kind and character and at such places as he/she may deem necessary for the protection of pedestrians.
[Code 1975 §15.02(6)(B); CC 1989 §13-269]
The City Traffic Engineer, or his/her designated representative, may test traffic control devices under actual conditions of traffic.
The City Traffic engineer is hereby authorized to mark traffic lanes upon the roadway of any street or highway where a regular alignment of traffic is necessary.
Where such traffic lanes have been marked, it shall be unlawful for the operator of any vehicle to fail or refuse to keep such vehicle within the boundaries of any such lane except when lawfully passing another vehicle or preparatory to making a lawful turning movement.
