§ 28-125  CONTROL SIGNALS.
   (a)   Whenever traffic is controlled by traffic- control signals exhibiting the words “Go,” “Caution” or “Stop” or exhibiting different colored lights successively one at a time, or with arrows, the following colors shall be used and the terms and lights shall indicate and apply to drivers of vehicles and pedestrians as follows.
      (1)   Green alone or “Go.”
         a.   Vehicular traffic facing the signal, except at an intersection where traffic is controlled by a police officer, may proceed straight through or turn left or right unless a sign at such place prohibits either turn. But 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.   Pedestrians facing the signal may proceed across the roadway within any marked or unmarked crosswalk.
      (2)   Yellow alone or “Caution” when shown following the green or “Go” signal.
         a.   Vehicular traffic facing the signal shall stop before entering the nearest crosswalk at the intersection, but if such stop cannot be made in safety, a vehicle may be driven cautiously through the intersection.
         b.   Pedestrians facing this signal are hereby advised that there is insufficient time to cross the roadways, and any pedestrians then starting to cross shall yield the right-of-way to all vehicles.
      (3)   Red alone or “Stop.”
         a.   Vehicular traffic facing the signal shall stop before entering the nearest crosswalk at an intersection or at such other point as may be indicated by a clearly visible line and shall remain standing until green or “Go” is shown alone; provided, however, that the driver of a vehicle which is stopped as close as practical at the entrance to a crosswalk on the near side of an intersection or, if there is no crosswalk, then at the entrance to the intersection, in obedience to a red or “Stop” signal, may make a right turn when a sign is erected at the intersection stating “Right Turn on Red After Stop,” or may make a left turn on red at the intersection of two one-way streets when a sign is erected at the intersection stating “Left Turn on Red After Stop,” but before proceeding shall make a careful observation for and yield the right-of-way to pedestrians and other traffic proceeding as directed by the signal. Such turns are prohibited against a red or “Stop” signal at any signalized intersection when a sign is not erected at the intersection permitting such turns against a red or “Stop” signal.
         b.   No pedestrian facing such signal shall enter the highway unless he can do so safely and without interfering with any vehicular traffic.
      (4)   Red with arrow.
         a.   Green arrow (steady). 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 other traffic lawfully using the intersection.
         b.   Red arrow (flashing). When a red arrow is illuminated by rapid intermittent flashes, drivers of vehicles shall stop before entering the nearest crosswalk at an intersection or at a limit line when marked and shall then be privileged to make the movement indicated; provided, that no interference is offered pedestrians or vehicles lawfully on the highway.
         c.   No pedestrian facing such signal shall enter the highway unless he can do so safely and without interfering with any vehicular traffic.
   (b)   In the event a 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 can have no application. Any stop required shall be made at a sign or marking on the pavement indicating where the stop shall be made, but in the absence of any sign or marking the stop shall be made at the signal.
