The mayor or such other duly authorized person as may be designated by the city council shall place and maintain traffic-control signs, signals and devices when and as required under this article or other traffic ordinances of the city to make effective the provisions of this chapter or other ordinances, and may place and maintain such additional traffic-control devices as he or she may deem necessary to regulate traffic under this chapter or other traffic ordinances of the city, or under state law, or to guide or warn or control traffic.
(1992 Code, sec. 10.201)
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.
(Ordinance adopting Code)
All traffic-control signs, signals, devices and markings heretofore placed or erected, and now in use for the purpose of regulating, warning or guiding traffic are hereby affirmed, ratified and declared to be the official traffic-control devices of the city. Provided, however, such traffic-control devices are not inconsistent with the provisions of state law or this article.

(a) 
Flashing red (stop signal).

Every stop sign erected pursuant to this chapter shall bear the word “stop,” in letters not less than eight inches (8") in height, and such signs shall at nighttime be rendered luminous by steady or flashing internal illumination, or by a fixed floodlight projected on the face of the sign by efficient reflecting elements on the face of the sign.
