A. 
The display of signal lights, arrows and words shall be deemed to have the following meanings and requires the appropriate response on the part of vehicular traffic and pedestrians:
1. 
Green Alone, "Go":
a. 
Vehicular traffic facing the signal, except when prohibited, may proceed straight through or turn right or left unless an official sign at such place prohibits such turn, but any vehicle and any pedestrian lawfully within the intersection or adjacent crosswalk at the time the signal displays green shall have the right of way over such vehicular traffic; and
b. 
Pedestrian traffic, facing a green signal may proceed across the roadway within any marked or unmarked crosswalk unless a "Walk" signal indicator is operating;
2. 
Steady Yellow or Amber Alone, "Caution":
a. 
The showing of such signal color following green shall constitute a warning that the "Red" or "Stop" signal will be exhibited immediately thereafter; and
b. 
Vehicles facing the signal shall stop before entering the near side crosswalk or at the limit line, if it is marked, unless the vehicle is so near the limit line when the "caution" signal first flashes that a stop cannot be made in safety, in which event vehicles may proceed cautiously through the intersection and clear the same before the "red" signal flashes;
3. 
Red Alone, "Stop":
a. 
Vehicular traffic facing the signal shall stop before entering the crosswalk and shall remain standing until green or "go" is shown alone. Except where official signs are erected prohibiting such turns, vehicles in the right traffic lane, after making a full stop as required, may enter the intersection cautiously and make a right turn, but such vehicles shall yield the right of way to any pedestrians or other traffic in the intersection and the turn shall be made so as not to interfere in any way with traffic proceeding on a green signal indication on the cross street; and
b. 
Pedestrians facing the signal shall not enter or cross the roadway when such movement interferes with traffic proceeding on a green signal indication on the cross street, or when the movement cannot be made in safety. No pedestrian facing such signal shall enter the roadway until the green or "go" is shown alone unless authorized to do so, by a pedestrian "walk" signal;
4. 
Steady Red with Green Arrow:
a. 
Vehicular traffic facing such signal when in the proper traffic lane may cautiously enter the intersection only to make the movement indicated by the arrow, but shall yield the right- of- way to pedestrians lawfully within a crosswalk and to other traffic lawfully using the intersection. If the movement indicated by the green arrow is a left turn, the left turn shall be made only on the red with green arrow signal; and
b. 
No pedestrian facing such signal shall enter the roadway until the green or "go" is shown alone unless authorized so to do by a pedestrian "walk" signal; and
5. 
Green Arrows Alone: Whenever vehicular traffic movements are controlled by green arrows alone and not displayed with any other signal indication, vehicles facing such signals may make the movements indicated by the green arrows and the movements shall be made only when the green arrows are displayed.
[Prior Code, Chapter 20]
A. 
Special pedestrian control signals exhibiting the words "Walk," "Wait" or "Don't Walk" shall regulate pedestrian movement 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; and
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 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 traffic signs or signals, it shall require obedience by vehicular traffic as follows:

2. 
"Steady Yellow Alone":
a. 
Vehicular traffic facing the signal is thereby warned that the red of "Stop" signal will be exhibited immediately thereafter, and such vehicular traffic shall not enter or be crossing the intersection or pass the signal when the red or "Stop" signal is exhibited; and
b. 
No pedestrian shall enter the roadway or intersection on which the signal controls vehicular traffic until steady red alone is shown;
3. 
"Steady Red":
a. 
Vehicular traffic facing the signal shall stop before entering the crosswalk on the near side of the intersection, and shall remain standing until flashing yellow is shown alone;
b. 
Pedestrians may proceed across the road controlled by the signal, and shall be given the right of way by the drivers of all vehicles; and
4. 
"Steady Red and Steady Yellow Combined":
a. 
Vehicular traffic facing the signal is thereby warned that the flashing yellow signal will be exhibited immediately thereafter, and that such vehicular traffic shall remain standing until the flashing yellow is shown alone; and
b. 
Pedestrians are thereby warned that the flashing yellow signal is about to be shown, and shall not enter the signal-controlled roadway or intersection, or in a direction which conflicts with the movement of vehicular traffic; but any pedestrian who has partially completed his crossing shall proceed to the nearest sidewalk or safety island, and shall be given the right of way by the drivers of all vehicles.
