Whenever traffic is controlled by traffic control signals exhibiting different colored lights successively one at a time, or with lighted green arrows, only the following colors shall be used, and such terms and lights and lighted green arrows shall indicate and apply to drivers of vehicles and pedestrians as follows:
A. Circular Green (Alone):
1. 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 shall yield the right of way to other vehicles and to pedestrians lawfully within the intersection at the time such signal is exhibited.
2. Pedestrians facing the signal may proceed across the roadway within any marked or unmarked crosswalk.
B. Steady Yellow:
1. Vehicular traffic facing a steady yellow signal is thereby warned that the related green movement is being terminated or that a red indication will be exhibited immediately thereafter when vehicular traffic may not enter the intersection.
2. Pedestrians facing a steady yellow signal are thereby advised that there is insufficient time to cross the roadway, and no pedestrian shall start to cross.
C. Steady Red Indication:
1. Vehicular traffic facing a steady red signal alone must stop at a clearly marked stop line, but if none, before entering the crosswalk on the near side of an intersection, or if none, then before entering the intersection, and shall remain standing until an indication to proceed is shown except as provided in subsections C2 and E1 of this section.
2. When a sign is in place permitting a turn, vehicular traffic facing a steady red signal may cautiously enter the intersection to make the turn indicated by such sign after stopping as required by subsection C1 of this section. Such vehicular traffic shall yield the right of way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.
3. No pedestrian facing such signal shall enter the roadway unless he can do so safely without interfering with any vehicular traffic or unless a separate "Walk" indication is shown.
D. Green Straight Through Arrow Alone:
1. Vehicular traffic facing the signal may proceed straight through, but shall not turn right or left. Such vehicular traffic shall yield the right of way to other vehicles and to pedestrians legally within the intersection at the time such signal is exhibited.
2. Pedestrians facing the signal may proceed across the roadway within the appropriate marked or unmarked crosswalk.
E. Green Turn Arrow (With Circular Green, With Steady Yellow, With Steady Red Or With Green Straight Through Arrow):
1. Vehicular traffic facing the signal shall comply with the meaning of the circular green, steady yellow, steady red or green straight through arrow indication as if it were shown alone; except, that such vehicular traffic may cautiously enter the intersection to make the movement indicated by the green turn arrow. Vehicular traffic shall yield the right of way to pedestrians lawfully within a crosswalk and to other traffic lawfully using the intersection.
2. Pedestrians facing such signal shall comply with the meaning of the circular green, steady yellow, steady red or straight through arrow indication as if it were shown alone.
F. Signals At Other Than Intersections: In the event an official traffic control signal or flashing red signal is erected and maintained at a place other than an intersection, the provisions of this section and section 7-2-6 of this chapter shall be applicable except as to provisions which by their nature can have no application. Any stop required shall be at a traffic sign or a marking on the pavement indicating where the stop shall be made. (1996 Code § 18-33)
