§ 70.20 TRAFFIC CONTROL SIGNAL LEGEND.
   Whenever traffic is controlled by traffic control signs exhibiting the words “Go,” “Caution,” or “Stop” or exhibiting differently colored lights successively, the following colors only shall be used, and such terms and lights shall indicate 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 prohibits either such turn, but vehicular traffic shall yield the right-of-way to other vehicles and to pedestrians already within the intersection.
      (2)   Pedestrians facing the signal may proceed across the roadway within the crosswalk area, whether marked or not.
   (B)   Yellow alone or “Caution” when shown following the green or “Go” signal.
      (1)   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.
      (2)   Pedestrians facing such signal are thereby warned that there will not be sufficient time to safely cross the roadway, and any pedestrian then starting to cross shall yield the right-of-way to all vehicles.
   (C)   Red alone or “Stop.”
      (1)   Vehicles facing a red light from a steady or strobe beam stoplight shall not enter the intersection while the steady or strobe beam stoplight is emitting a red light; provided, except where prohibited by an appropriate sign, vehicular traffic facing a red light, after coming to a complete stop at the intersection, may enter the intersection to make a right turn, but such vehicle shall yield the right-of-way to pedestrians and to other traffic using the intersection. When the stoplight is emitting a steady yellow light, vehicles facing the yellow light are warned that a red light will be immediately forthcoming.
      (2)   When the stoplight is emitting a steady green light, vehicles may proceed with due care through the intersection subject to the rights of pedestrians and other vehicles as may otherwise be provided by law.
   (D)   Red with green arrow.
      (1)   Vehicular traffic facing such signal may cautiously enter the intersection and continue the movement in the direction indicated by such arrow but shall not interfere with other traffic.
      (2)   No pedestrian facing such signal shall enter the roadway unless he or she can do so without interfering with vehicular traffic.
