§ 71.03  TRAFFIC CONTROL SIGNAL LEGEND.
   Whenever traffic is controlled by traffic control signals (Ch. 76, Sch. I) exhibiting the words “Go,” “Caution” or “Stop” or exhibiting different colored lights successively one at a time, or with arrows, the following colors only shall be used and the terms and light shall indicate and apply to drivers of vehicles and pedestrians as follows.
   (A)   Green alone or “Go.”
      (1)   Vehicular traffic facing the signal may proceed straight through or turn right or left unless a sign at the place prohibits either 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 the signal is exhibited.
      (2)   Pedestrians facing the signal may proceed across the roadway within any marked or unmarked crosswalk.
   (B)   Yellow alone or “Caution” when shown following the green or “Go” signal.

      (2)   No pedestrian facing the signal shall enter the roadway until the green or “Go” is shown.
   (C)   Red alone or “Stop.”
      (1)   Vehicular traffic facing the signal shall stop before entering the crosswalk on the near side of the intersection or, if none, then before entering the intersection shall remain standing until green or “Go” is shown alone; provided, however, that if a sign is not erected prohibiting turns on red lights, the vehicles may turn right on red lights after coming to a complete stop. Streets on which right turns on red are not allowed are set out in Ch. 76, Sch. II hereof.
      (2)   No pedestrian facing the signal shall enter the roadway unless the green or “Go” is shown alone unless authorized to do so by a pedestrian “Walk” signal.
   (D)   Red with green arrow.
      (1)   Vehicular traffic facing the signal 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.
      (2)   No pedestrian facing the signal shall enter the roadway until the green or “Go” is shown.
   (E)   Placement of official traffic control signal. In the event an official traffic control signal is erected and maintained at a place other than in 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 payment indicating where the stop shall be made, but in the absence of any sign or marking the stop shall be made at the signal.
