The city traffic engineer shall cause to be placed and maintained traffic-control signs, signals, and devices when and as required under the traffic ordinances of this city to effect and enforce the provisions of said ordinances, and may place and maintain such additional traffic-control devices as he may deem necessary to regulate traffic under the traffic ordinances of this city or under state law, or to guide or warn traffic.
(1996 Code, sec. 10.601)
(a) 
The city traffic engineer shall determine the necessity for installation and maintenance of traffic-control devices on the public streets and highway within the corporate limits of the city based upon a traffic and engineering study. It shall be the duty of the traffic engineer to install or cause to be installed all such traffic-control devices determined by him to be necessary on the basis of such traffic and engineering studies. Whenever the traffic engineer has erected and installed such traffic-control devices, it shall be his further duty to file a report with the city secretary stating the type of any such traffic-control devices that were so installed and the date when and location where such devices were installed.
(b) 
It shall further be the duty of the city traffic engineer, and he is hereby authorized, to remove any and all traffic-control devices which he determines in a like manner to be no longer necessary.
(c) 
It shall also be the duty of the traffic engineer to maintain any other existing traffic-control devices and any and all existing traffic-control devices previously installed within the corporate limits of the city shall be deemed to be properly installed in accordance with the provisions of this article until such time as they are removed or caused to be removed by the city traffic engineer pursuant to the terms of this article.
(1996 Code, sec. 10.602)
(a) 
All signs and signals required hereunder for a particular purpose shall as 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 state law or this chapter shall be official traffic-control devices.
(b) 
Any traffic-control device installed pursuant to the authority of this article shall be in conformity with the Manual on Uniform Traffic Control Devices, Volumes 1 and 2, promulgated by the state department of transportation pursuant to article 6701d, section 29 and any other applicable state law.
(1996 Code, sec. 10.603)
The driver of any motor vehicle shall obey the instructions of any traffic-control device applicable to such vehicle installed in accordance with the provisions of this article, unless otherwise directed by a peace officer, subject to the exceptions granted to the operator of an authorized emergency vehicle in accordance with applicable state law.
(1996 Code, sec. 10.604)
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 or other traffic-control device is not in proper position and sufficiently legible to be seen by an ordinarily observant person.
(1996 Code, sec. 10.605)
(a) 
Whenever traffic is controlled by traffic-control signals exhibiting the word “GO,” “CAUTION,” or “STOP” arrows, the following colors only shall be used and said terms and lights indicate and apply to drivers of vehicles and pedestrians as follows:
(1) 
Green alone or “GO.”
(A) 
Vehicular traffic facing the signal may proceed straight through or turn right or left unless a sign at such place prohibits either such turns. 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) 
Pedestrians facing the signal may proceed across the roadway within any marked or unmarked crosswalk.
(2) 
Yellow alone or “CAUTION” when shown following the green or “GO” signal.
(A) 
Vehicular traffic facing the signal is thereby warned that the red or “STOP” signal will be exhibited immediately thereafter and such vehicular traffic shall not enter or be crossing the intersection when the red or “STOP” signal is exhibited.
(B) 
Pedestrians facing such signal are thereby advised that there is insufficient time to cross the roadway, and pedestrians then starting to cross shall yield the right-of-way to all vehicles.
(3) 
Red alone or “STOP.”
(A) 
Vehicular traffic facing the signal 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 green or “GO” is shown alone.
(B) 
No pedestrian facing such signal shall enter the roadway.
(b) 
In the event an official traffic-control signal is erected and maintained at a place other than an intersection, the provisions of this article 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.
(1996 Code, sec. 10.606)
Whenever special pedestrian control signals exhibiting the word “WALK” or “WAIT” are in place, such signals shall indicate as follows:
(1) 
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.
(2) 
Wait.
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 “WAIT” signal is showing.
(1996 Code, sec. 10.607)
Whenever flashing red or yellow signals are used they shall require obedience by vehicular traffic as follows:
(1) 
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, and the right to proceed shall be subject to the rules applicable after making a stop at a stop sign.
(2) 
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 only with caution.
(1996 Code, sec. 10.608)
(a) 
No person shall place, maintain, or display upon or in view of any highways, roads, streets, boulevards, parkways, and alleyways 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 sign or signal, and no person shall place or maintain nor shall any public authority permit upon any highways, roads, streets, boulevards, pathways, and alleyways any traffic sign or signal bearing thereon any commercial advertising. This shall not be deemed to prohibit the erection upon private property adjacent to highways, roads, streets, boulevards, pathways, and alleyways of signs giving useful directional information and of a type that cannot be mistaken for official signs.
(b) 
Every such prohibited sign, signal, or marking is hereby declared to be a public nuisance, and the authority having jurisdiction over the highways, roads, streets, boulevards, pathways, and alleyways is hereby empowered to remove the same or cause it to be removed without notice.
(1996 Code, sec. 10.609)
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 insignia thereon, or any other part thereof.
(1996 Code, sec. 10.610)
The city traffic engineer is hereby authorized:
(1) 
To designate and maintain, by appropriate devices, marks, or lines upon the surface of the roadway, crosswalks at intersections where in his opinion there is particular danger to pedestrians crossing the roadway, and at such other places as he may deem necessary.
(2) 
To establish safety zones of such kind and character and at such places as he may deem necessary for the protection of pedestrians.
(3) 
To mark lanes for traffic on street pavements at such places as he may deem advisable, consistent with the traffic ordinances of this city.
(1996 Code, sec. 10.611)
(a) 
The chief of police shall have authority to establish and designate and to cause appropriate signage or other appropriate traffic-control devices or markings to be erected or placed, that establish zones in which construction or maintenance of streets, utilities or other facilities in city streets or rights-of-way is being conducted, and in which fines for motor vehicles shall be twice the maximum amount when workers are present, as provided in section 542.404, Texas Transportation Code.
(b) 
The chief of police shall have authority to reduce the prima facie speed limit on a street within a construction or maintenance zone that has been established when, in the opinion of the chief, a special hazard exists that justifies the reduced speed limit.
(c) 
In the event that the chief of police has reason to believe that the speed limit in a construction or maintenance zone should be altered, but no special hazard exists, he or she shall have authority to conduct or obtain an engineering and traffic investigation to determine if the speed limit should be altered.
