(Ord. O-74-44 § 1 (part), 1974).

10.45.050 Traffic-control signal legend.
A. Whenever traffic is controlled by traffic-control signals exhibiting different colored lights, or colored arrows, successively one at a time or in combination, only the colors green, yellow and red shall be used, except for special pedestrian-control signals carrying a word legend as provided in Section 10.45.080, and the lights, arrows and combinations thereof 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 10.45.080, 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 circular yellow or yellow arrow signal is thereby warned that the related green movement is being terminated or that a red indication will be exhibited immediately thereafter.
b. Pedestrians facing a steady circular yellow or yellow arrow signal, unless otherwise directed by a pedestrian-control signal as provided in Section 10.45.080, 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.
a. Vehicular traffic facing a steady circular 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 or, if none, then before entering the intersection, and shall remain standing until an indication to proceed is shown, except that:
i. Such vehicular traffic, after coming to a stop and yielding the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection, may make a right turn unless an official sign has been erected prohibiting such right turn;
ii. Such vehicular traffic, when proceeding on a one-way street, and after coming to a stop, may make a left turn onto a one-way street upon which traffic is moving to the left of the driver. Such turn shall be made only after yielding the right-of-way to pedestrians and other traffic proceeding as directed. No turn shall be made pursuant to this subparagraph at an intersection where an official sign has been erected prohibiting such left turn.
b. Pedestrians facing a steady circular red signal alone shall not enter the roadway, unless otherwise directed by a pedestrian-control signal as provided in Section 10.45.080.
c. Vehicular traffic facing a steady red arrow signal may not enter the intersection to make the movement indicated by such arrow and, unless entering the intersection to make such other movement as is permitted by other indications shown at the same time, shall stop at a clearly marked stop line, but, if none, before entering the crosswalk on the near side of the intersection or, if none, then before entering the intersection, and shall remain standing until an indication to make the movement indicated by such arrow is shown.
d. Pedestrians facing a steady red arrow signal shall not enter the roadway, unless otherwise directed by a pedestrian-control signal as provided in Section 10.45.080.
4. Nonintersection Signal.
a. 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 have no application.
b. Any stop required at a nonintersection signal shall be made at a sign or pavement marking 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.
B. Any person who violates any provision of this section commits a Class 3 traffic offense. (Ord. O-80-76 § 6, 1980; Ord. O-75-96 § 64, 1975; Ord. O-74-44 § 1 (part), 1974).

10.45.060 Flashing signals.
A. Whenever an illuminated flashing red or yellow signal is used in conjunction with a traffic sign or a traffic signal or as a traffic beacon, it shall require obedience by vehicular traffic as follows:
1. When a red lens is illuminated with rapid intermittent flashes, drivers of vehicles shall stop at a clearly marked stop line, but, if none, before entering the crosswalk on the near side of the intersection or, if none, then at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway 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. When a yellow lens is illuminated with rapid intermittent flashes, drivers of vehicles may proceed past such signal and through the intersection or other hazardous location only with caution.
B. This section shall not apply at railroad grade crossings. Conduct of drivers of vehicles approaching railroad crossings shall be governed by provisions of Sections 10.12.010 through 10.12.040 of this title.
C. Any person who violates any provision of this section commits a Class 3 traffic offense. (Ord. O-75-96 § 65, 1975; Ord. O-74-44 § 1 (part), 1974).

10.45.070 Lane-use-control signals.
A. Whenever lane-use-control signals are placed over the individual lanes of a street or highway, such signals shall indicate and apply to drivers of vehicles as follows:
1. Downward-pointing Green Arrow (Steady). A driver facing such signal may drive in any lane over which the green arrow signal is located.
2. Yellow "X" (Steady). A driver facing such signal is warned that the related green arrow movement is being terminated and shall vacate in a safe manner the lane over which the steady yellow signal is located to avoid, if possible, occupying that lane when the steady red "X" signal is exhibited.
3. Yellow "X" (Flashing). A driver facing such signal may use the lane over which the flashing yellow signal is located for the purpose of making a left turn or a passing maneuver, using proper caution, but for no other purpose.
4. Red "X" (Steady). A driver facing such signal shall not drive in any lane over which the red signal is exhibited.
B. Any person who violates any provision of this section commits a Class 3 traffic offense. (Ord. O-75-96 § 66, 1975; Ord. O-74-44 § 1 (part), 1974).

10.45.080 Pedestrian-control signals.
Whenever special pedestrian-control signals exhibiting the words "Walk" or "Don't Walk" are in place, such signals shall indicate as follows:
A. "Walk": While the "Walk" indication is illuminated, pedestrians facing such signal may proceed across the roadway in the direction of the signal indication.
B. "Don't Walk" (flashing): Whenever the "Don't Walk" indication is flashing, no pedestrian shall start to cross the roadway in the direction of the indication, but any pedestrian who has partly completed his crossing during the "Walk" indication shall proceed to a sidewalk or to a safety island, and all drivers of vehicles shall yield to any such pedestrian.
C. "Don't Walk" (steady): While the "Don't Walk" indication is steadily illuminated, no pedestrian shall enter the roadway in the direction of the signal indication.
D. Whenever a signal system provides for the stopping of all vehicular traffic and the exclusive movement of pedestrians, and "Walk" and "Don't Walk" signal indications control such pedestrian movement, pedestrians may cross in any direction between corners of the intersection offering the shortest route within the boundaries of the intersection while the "Walk" indication is exhibited, if signals and other official devices direct pedestrian movement in such manner consistent with Section 10.45.050(A)(3)(d).
E. Any person who violates any provision of this section commits a Class 3 traffic offense. (Ord. O-97-62 § 19, 1997; Ord. O-78-79 § 3, 1978; Ord. O-77-86 § 24, 1977; Ord. O-74-44 § 1 (part), 1974).

10.45.090 When signals are inoperative or malfunctioning.
A. Whenever a driver approaches an intersection and faces a traffic-control signal which is inoperative or which remains on steady red or steady yellow during several time cycles, the rule controlling entrance to a through street or highway from a stop street or highway, as provided in Section 10.09.020 of this title, shall apply until a police agent assumes control of traffic or until normal operation is resumed.
B. In the event that any traffic-control signal at a place other than an intersection should cease to operate or should malfunction as herein set forth, drivers may proceed through the inoperative or malfunctioning signal only with caution, as if the signal were one of flashing yellow.
C. Whenever a pedestrian faces a pedestrian-control signal, as provided in Section 10.45.080, which is inoperative or which remains on "Don't Walk" or "Wait" during several time cycles, such pedestrian shall not enter the roadway unless he can do so safely and without interfering with any vehicular traffic.
D. Any person who violates any provision of this section commits a Class 3 traffic offense. (Ord. O-97-62 § 20, 1997; Ord. O-75-96 § 67, 1975; Ord. O-74-44 § 1 (part), 1974).

10.45.100 Traffic lanes.
Where traffic lanes have been marked, as authorized in Section 10.69.080 of this title, a vehicle shall be driven as nearly as practicable entirely within a single lane and shall not be moved from such lane until such movement can be made with safety. Any person who violates any provision of this section commits a Class 3 traffic offense. (Ord. O-94-34 § 14, 1994; Ord. O-75-96 § 68, 1975; Ord. O-74-44 § 1 (part), 1974).

10.45.110 Barricades-Driving in highway work area.
A. Whenever barricades are erected to close off part or all of a street or highway, as authorized in Section 10.69.080 of this title, no person shall drive around, through, or between such barricades or into the barricaded area except as directed or permitted by official signs or in compliance with directions of a police agent or other authorized person.
