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, the following colors only shall be used, and the 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 at that place prohibits either turn. But vehicular traffic shall yield the right-of-way to other vehicles and to pedestrians lawfully within the intersection 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.
(1) Vehicular traffic facing the signal shall stop before entering the nearest crosswalk at the intersection, but if the stop cannot be made in safety, a vehicle may be driven cautiously through the intersection.
(2) Pedestrians facing this signal are thereby advised that there is insufficient time to cross a roadway, and any pedestrian then starting to cross shall yield the right-of-way to all vehicles.
(C) Red alone, or "Stop."
(1) Vehicular traffic facing the signal shall stop before entering the nearest crosswalk at an intersection, or at any other point as may be indicated by a clearly visible line, and shall remain standing until green or "Go" is shown alone.
(2) No pedestrian facing the signal shall enter the roadway unless he or she can do so safely and without interfering with any vehicular traffic.
(3) Except where prohibited by an appropriate sign, vehicular traffic facing a red signal controlling traffic passing straight through an intersection, after coming to a complete stop at the intersection, may enter the intersection to make a right turn, but the vehicle shall yield the right-of-way to pedestrians and other traffic using the intersection.
(D) Red with green arrow.
(1) Vehicular traffic facing the signal may cautiously enter the intersection, only to continue movement in the direction indicated by the arrow, but shall not interfere with other traffic.
(2) No pedestrian facing this signal shall enter the roadway unless he or she can do so safely and without interfering with any vehicular traffic.
