(a) Whenever traffic is controlled by traffic-control signals exhibiting the words “GO”, “CAUTION”, or “STOP”, or exhibiting different colored lights successively one (1) at a time or with arrows, the following colors only 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” means:
(A) Vehicular traffic facing the signal, except when prohibited under § 27-51-802, may proceed straight through or turn right or left 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 to pedestrians lawfully within the intersection or an adjacent crosswalk at the time the signal is exhibited,
(B) Pedestrians facing the signal may proceed across the roadway within any marked or unmarked crosswalk;
(2) Steady yellow alone means:
(A) Vehicular traffic facing the signal is warned that the red or “STOP” signal will be exhibited immediately thereafter, and vehicular traffic shall not enter the intersection when the red or “STOP” signal is exhibited.
(B) Pedestrians facing the signal are advised that there is insufficient time to cross the roadway, and any pedestrian then starting to cross shall yield the right-of-way to all vehicles;
(3) Steady red alone or “STOP” means:
(A) 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 and shall remain standing until green or “GO” is shown alone, except that:
(i) Vehicular traffic facing the signal, after coming to a complete stop, may cautiously enter the intersection for the purpose of making a right turn only, unless there is a sign prohibiting the turn; and
(ii) Vehicular traffic in the left lane of a one-way street facing such signal, after coming to a complete stop, may cautiously enter the intersection for the purpose of making a left turn into the left lane of another one-way street only, unless there is a sign prohibiting such turn.
(B) No pedestrian facing the signal shall enter the roadway unless he or she can do so safely and without interfering with any vehicular traffic; and
(4) Steady red with green arrow means:
(A) 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.
(B) No pedestrian facing the signal shall enter the roadway unless he or she can do so safely and without interfering with any vehicular traffic;
(b)
(1) In the event an official 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.
(2) 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.
(c) The operator of any streetcar shall obey the signals as applicable to vehicles.
(d) Whenever special pedestrian-control signals exhibiting the words “WALK” or “WAIT” or “DON'T WALK” are in place, such signals shall indicate as follows:
(1) “WALK” means pedestrians facing the 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” means no pedestrian shall start to cross the roadway in the direction of such signal, but any pedestrian who has partially completed his or her crossing on the walk signal shall proceed to a sidewalk or safety island while the wait signal is showing.
