[Ord. No. 99-43, § 3, 12-1-1999]
(a) 
Whenever traffic is controlled by traffic control signals exhibiting different colored lights, or colored lighted arrow, 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 such lights shall indicate and apply to drivers of vehicles and pedestrians as follows:
(1) 
Green indications:
a. 
Vehicular traffic facing a circular green signal may proceed straight or turn right or left, unless a sign prohibits such turns; however, vehicular traffic, including vehicles turning right or left, shall yield the right-of-way to other vehicles and 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, 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. Vehicular traffic facing the signal shall be stopped before entering the crosswalk on the near side of the intersection or, if none, then before entering the intersection, and shall remain standing until the "green" or "go" is shown and shall not, prior to reaching such intersection, make any turn over or through private property in order to avoid such signal; provided however, a righthand turn shall be permitted after vehicular traffic reaches a complete stop at intersections when safety permits such a turn and no sign forbids it.
(2) 
Steady yellow indication:
a. 
Vehicular traffic approaching a steady yellow signal or arrow indication is hereby warned that the related green movement is being terminated, or that a red indication will be exhibited immediately thereafter, signalling that vehicular traffic shall not enter or turn at such intersection.
b. 
Pedestrians facing a steady yellow signal, unless otherwise directed by a pedestrian control signal, are hereby 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:
a. 
Vehicular traffic approaching a steady red signal alone, or red arrow, shall stop before entering the crosswalk, on the near side of the intersection, or before making such turn, and shall remain standing until a green indication is shown.
b. 
Unless otherwise directed by a pedestrian control signal, pedestrians facing a steady red signal alone shall not enter the roadway.
(b) 
If an official traffic control 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 in the pavement indicating where the stop shall be made or, in the absence of such sign or marking, the stop shall be made at the signal.
[Ord. No. 99-43, § 3, 12-1-1999]
Whenever special pedestrian control signals exhibiting the words "Walk," "Wait" or "Don't Walk" are in place, such signals shall indicate as follows:
(1) 
Pedestrians facing a "Walk" signal may proceed across the roadway in the direction of the signal, and shall be given the right-of-way by drivers of all vehicles.
(2) 
No pedestrian shall start to cross the roadway in the direction of a "Wait" or "Don't Walk" signal, but any pedestrian who has partially completed his crossing on the "Walk" signal shall proceed to a sidewalk safety zone while the "Wait" or "Don't Walk" signal is showing.
[Ord. No. 99-43, § 3, 12-1-1999]
(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 flashers, drivers of vehicles shall stop before entering the nearest crosswalk at an intersection or at a stop 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 such stop at a stop sign.
(2) 
Flashing yellow (caution signal). When a yellow lens is illuminated with rapid intermittent flashers, drivers of vehicles may proceed through the intersection or past such signal only with caution.
(b) 
This section shall not apply at railroad grade crossings where flashing signals are used.
[Ord. No. 99-43, § 3, 12-1-1999]
(a) 
No person shall place, maintain or display upon or in view of any highway any unauthorized sign, signal, marking or device which is supposed to be or is an imitation of or resembles an official traffic control device, 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 traffic control device or any railroad sign or signal.
(b) 
No person shall place or maintain nor shall any public authority permit upon any roadway, street or highway of the city any traffic sign or signal bearing thereon any commercial advertising.
(c) 
This section shall not be deemed to prohibit the erection upon private property, adjacent to highways, of signs giving useful directional information and of a type that cannot be mistaken for official signs or signals.
(d) 
Every sign, signal or marking prohibited by this section is hereby declared to be a public nuisance, and the city traffic division is hereby empowered to remove such prohibited sign, signal or marking or cause it to be removed without notice.
