(a) 
All traffic-control devices including signs, signals and markings (pavement and/or curb) installed or used for the purpose of directing and controlling traffic within the city shall conform with the manual and specifications adopted by the state transportation commission as provided in V.T.C.A., Transportation Code, section 544.001. All signs, signals and markings erected or used by the city must conform to the manual and specifications adopted under V.T.C.A., Transportation Code, section 544.001. All existing traffic-control devices and those erected in the future by the city being consistent with the manual and specifications, state law and this section shall be official traffic-control devices.
(b)

Said traffic-control devices shall be installed immediately, or as soon as such specific device, sign or signal can be procured.
(c) 
Whenever the mayor has erected and installed any official traffic-control device, signal or sign at any location in the city or has caused the same to be done under his direction, in obedience to this section and the manual, he shall thereafter file a report with the city secretary in writing and signed officially by the chief of police, stating the type of traffic-control device, sign or signal, and when and where the same was erected and installed. The city secretary shall file and maintain such report of the chief of police among the official papers of the office of the city secretary.

(1984 Code, sec. 12-146; 1998 Code, sec. 10.501; Ordinance adopting 2017 Code)
The city council shall cause to be placed traffic-control signs, signals and devices when and as required under this chapter to make effective the provisions of this chapter, and may place and maintain such additional traffic-control devices as it may deem necessary to regulate traffic under this chapter or under state law, or to guide or warn traffic.
(1984 Code, sec. 12-147; 1998 Code, sec. 10.502)
The driver of any vehicle, motor vehicle or animal shall obey the instructions of any official traffic-control device, sign, signal or marking applicable thereto placed in accordance with this chapter, unless otherwise directed by a police officer, subject to the exceptions granted the driver of an authorized emergency vehicle permitted by this chapter.
(1984 Code, sec. 12-148; 1998 Code, sec. 10.503)
No provision of this chapter for which signs are required shall be enforced against an alleged violator if, at the time and place of the alleged violation, an official sign is not in proper position and sufficiently legible to be seen by an ordinarily observant person. Whenever a particular section does not state that signs are required, such section shall be effective even though no signs are erected or in place.
(1984 Code, sec. 12-149; 1998 Code, sec. 10.504)
All traffic-control signs, signals, devices, and markings placed or erected prior to the adoption of this code and in use for the purpose of regulating, warning or guiding traffic are hereby affirmed, ratified and declared to be official traffic-control devices, provided such traffic-control devices are not inconsistent with the provisions of this chapter or state law.
(1984 Code, sec. 12-150; 1998 Code, sec. 10.505)
(a) 
No person shall place, maintain or display upon or in view of any road, street or highway any 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 signal or sign, and no person shall place or maintain nor shall any public authority permit upon any highway or street any traffic signal or sign bearing thereon any commercial advertising. This shall not be deemed to prohibit the erection, upon private property adjacent to streets or highways, of signs giving useful directional information and of a type that cannot be mistaken for official signals.
(b) 
Every such prohibited sign, signal or marking is declared to be a public nuisance and the city is empowered to remove the same or cause it to be removed without notice.
(1984 Code, sec. 12-151; 1998 Code, sec. 10.506)
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 inscription, shield or insignia thereon or any other part thereof.
(1984 Code, sec. 12-152; 1998 Code, sec. 10.507)
The city council from time to time shall designate intersections at which traffic shall be controlled by electric traffic-control signals or lights and shall cause such signals or lights to be installed and maintained at such intersections.
(1984 Code, sec. 12-153; 1998 Code, sec. 10.508)
(a) 
Whenever traffic is controlled by traffic-control signals exhibiting different colored lights, or colored lighted arrows, successively one at a time or in combination, only the colors green, red and yellow shall be used, except for special pedestrian signals carrying a word legend, and said lights shall indicate and apply to drivers of vehicles and pedestrians as follows:
(1) 
Green indication.
(A) 
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.
(B) 
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 such 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.
(C) 
Unless otherwise directed by a pedestrian control signal as provided in section 12.02.010, pedestrians facing any green signal, except when the sole green signal is a turn arrow, may proceed across the roadway within any marked or unmarked crosswalk.
(2) 
Steady yellow indication.
(A) 
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.
(B) 
Pedestrians facing a steady yellow signal, unless otherwise directed by a pedestrian control signal as provided in section 12.02.010, are thereby advised that there is insufficient time to cross the roadway before a red indication is shown, and no pedestrian shall then start to cross the roadway.
(3) 
Steady red indication.
Vehicular traffic facing a steady red signal alone shall stop at a clearly marked stop line, but, if none, before entering the crosswalk on the near side of the intersection, and may then turn right or, if the intersecting streets are both one-way streets and left turns are permissible, may turn left, after standing until the intersection may be entered safely, yielding the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection. Traffic not so turning shall remain standing until an indication to proceed is shown.
(b) 
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.
(1984 Code, sec. 12-154; 1998 Code, sec. 10.509)
Whenever special pedestrian control signals exhibiting the words “Walk” or “Don’t Walk” or “Wait” are in place, such signals shall indicate as follows:
(1) 
“Walk” signal.
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.
(2) 
“Don’t Walk” or “Wait” signal.
No pedestrian shall start to cross the roadway in the direction of such signal, but any pedestrian who has partially completed his crossing on the walk signal shall proceed to a sidewalk or safety zone while the “Don’t Walk” or “Wait” signal is showing.
(1984 Code, sec. 12-155; 1998 Code, sec. 10.510)
There may be installed, at such points on streets in the city as may be directed by the city council, appropriate signs notifying drivers of vehicles to come to a full stop. Such signs, devices or markings are to bear the word “stop” and to be located in such position and to be provided with letters of a size to be clearly legible from a distance of at least one hundred (100) feet along the street upon which the sign is placed. All such signs shall be illuminated at night or so placed as to be illuminated by streetlights or by the headlights of approaching motor vehicles. Whenever any such sign has been placed it shall be unlawful for the driver or operator of any vehicle to fail to stop in obedience thereto. The operator of any vehicle who has come to a full stop as required above shall be subject to the usual right-of-way rules prescribed by law.
(1984 Code, sec. 12-156; 1998 Code, sec. 10.511)
(a) 
Preferential right-of-way at an intersection may be indicated by stop signs or yield signs erected by the city pursuant to this chapter.
(b) 
Except when directed to proceed by a police officer or traffic-control signal, every driver of a vehicle approaching a stop intersection indicated by a stop sign shall stop, and after having stopped shall yield the right-of-way to any vehicle which has entered the intersection from another highway or which is approaching so closely on said highway as to constitute an immediate hazard during the time when such driver is moving across or within the intersection.
(c) 
The driver of a vehicle approaching a yield sign shall in obedience to such sign slow down to a speed reasonable for the existing conditions and shall yield the right-of-way to any vehicle in the intersection or approaching on another highway so closely as to constitute an immediate hazard during the time such driver is moving across or within the intersection. Provided, however, that if such a driver is involved in a collision with a vehicle in the intersection, after driving past a yield sign without stopping, such collision shall be deemed prima facie evidence of his failure to yield right-of-way.
(1984 Code, sec. 12-157; 1998 Code, sec. 10.512)
The city council is authorized:
(1) 
To designate and maintain, by appropriate devices, marks or lines upon the surface of the roadway, crosswalks at any intersection where, in their opinion, there is particular danger to pedestrians crossing the roadway, and at such other places as it may deem necessary.
(2) 
To establish safety, quiet, play and other zones of such kind and character and at such places as it may deem necessary for the protection of the public.
(3) 
To mark lanes for traffic on street pavements at such places as it may deem advisable, consistent with this chapter and other traffic ordinances of the city.
(1984 Code, sec. 12-158; 1998 Code, sec. 10.513)
(a) 
Whenever any ordinance designates any one-way street or alley, the city shall place and maintain signs giving notice thereof, and no such regulations shall be effective unless such signs are in place. Signs indicating the direction of lawful traffic movement shall be placed at every intersection where movement of traffic in the opposite direction is prohibited.
(b) 
Upon those streets and parts of streets and in those alleys which are designated as one-way streets or alleys, vehicular traffic shall move only in the indicated direction where signs indicating the direction of traffic are erected and maintained at every intersection where movement in the opposite direction is prohibited.
(1984 Code, sec. 12-159; 1998 Code, sec. 10.514)
(a) 
The city council is authorized to determine those intersections at which drivers of vehicles shall not make a right, left and/or U-turn, and shall place proper signs at such intersections. The making of such turns may be prohibited between certain hours of any day and permitted at other hours, in which event the same shall be plainly indicated on the signs or they may be removed when such turns are permitted. When authorized signs are erected indicating that no right, left or U-turn is permitted, no driver of a vehicle shall disobey the directions of such signs.
(b) 
No driver of any vehicle shall make a U-turn at any intersection within the city where there is suspended and operating a traffic-control signal light.
(1984 Code, sec. 12-160; 1998 Code, sec. 10.515)
