All traffic control signs, signals and devices shall conform to the manual and specifications approved by the State Highways and Transportation Commission or resolution adopted by the City Council of the City. All signs or signals required hereunder for a particular purpose shall so far as practicable be uniform as to type and location throughout the City.

No provision 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 traffic at an intersection is controlled by traffic control signals exhibiting different colored lights successively one at a time, or with arrows, said lights shall indicate and apply to drivers of vehicles and pedestrians as follows:
a. 
Green alone or green with arrow.
(1) 
Vehicular traffic facing the signal may proceed straight through or turn right or left unless a sign at such location prohibits either turn, except that vehicular traffic, including turning vehicles, shall yield the right-of-way to pedestrians and other vehicles lawfully within the intersection or an adjacent crosswalk at the time such signal was exhibited.
(2) 
Pedestrians facing the signal may proceed across the roadway within any marked or unmarked crosswalk, unless directed otherwise by a pedestrian signal.
b. 
Steady yellow alone.
(1) 
Vehicular traffic facing the signal shall stop before entering the crosswalk on the near side of the intersection, or if none, the intersection, unless so close to the intersection that a stop cannot be made in safety.
(2) 
No pedestrian facing the signal shall enter the roadway unless authorized to do so by a pedestrian "walk" signal.
c. 
Steady red alone.
(1) 
Vehicular traffic facing the signal shall stop before entering the crosswalk on the near side of the intersection, or if none, before entering the intersection and shall remain standing until a green signal is shown; provided, however, that 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 at such intersections where signs are erected prohibiting such right turn against red signal.
(2) 
No pedestrian facing such signal shall enter the roadway until the green is shown alone, unless authorized to do so by a pedestrian "walk" signal.
d. 
Steady red with green arrow or green arrow alone.
(1) 
Vehicular traffic facing such signal may cautiously enter the intersection only to make the movement indicated by such arrow, but shall yield the right-of-way to pedestrians lawfully within a crosswalk and to other traffic lawfully using the intersection.
(2) 
No pedestrian facing such signal shall enter the roadway until the green is shown alone, unless authorized to do so by a pedestrian "walk" signal.
e. 
Flashing red. When a red lens is illuminated with rapid intermittent flashes, vehicular traffic shall stop before entering the nearest crosswalk on the near side of the intersection, or if none, the intersection, and the driver, after having stopped, shall yield the right-of-way to any vehicle which has entered the intersection from another roadway or which is approaching so closely as to constitute an immediate hazard, but said driver, having so yielded, may proceed and the drivers of all other vehicles approaching the intersection shall yield the right-of-way to the vehicle so proceeding.
f. 
Flashing yellow. When a yellow lens is illuminated with rapid intermittent flashes, vehicular traffic may proceed through the intersection or past such signal only with caution.
2. 
The intersection controlled by electrically operated traffic signals shall be designated in Schedule IV hereof.

"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" 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.
A. 
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:
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 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.
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.

When lane direction control signals are placed over the individual lanes of a street or highway, vehicular traffic may travel in any lane over which a green signal is shown but shall not enter or travel in any lane over which a red signal is shown.
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.
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.
The City Traffic Engineer shall have authority to declare any street or part thereof a play street and to place appropriate signs or devices in the roadway indicating and helping to protect the same.
Whenever authorized signs are erected indicating any street or part thereof as a play street, no person shall drive a vehicle upon any such street or portion thereof except drivers of vehicles having business or whose residences are within such closed area, and then any said driver shall exercise the greatest care in driving upon any such street or portion thereof.
