Whenever traffic is controlled by traffic-control signals exhibiting different colored lights or colored lighted arrows successively, one at a time or in combination, only the colors green, red, or yellow may be used, except for special pedestrian signals under IC 9-4-1-36, and the lights indicate and apply to drivers of vehicles and pedestrians as follows:
(A) Green indication:
(1) Vehicular traffic facing a circular green signal may proceed straight through or turn right or left, unless a sign at such place prohibits either turn;
(2) Vehicular traffic, including vehicles turning right or left, shall yield right-of-way to other vehicles and to pedestrians lawfully within the intersection or an adjacent sidewalk at the time such signal is exhibited;
(3) Vehicular traffic facing a green arrow signal, shown alone or in combination with another indication, may cautiously enter the intersection only to make the movement indicated by such arrow, or such other movement as is permitted by other indications shown at the same time;
(4) Vehicular traffic shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection; and
(5) Unless otherwise directed by a pedestrian-control signal, pedestrians facing any green signal, except when the sole green signal is a turn arrow, may proceed across the roadway within any marked or unmarked crosswalk.
(B) Steady yellow indication:
(1) Vehicular traffic facing a steady circular yellow or yellow arrow signal is thereby warned that the related green movement is being terminated and that a red indication will be exhibited immediately thereafter; and
(2) Pedestrians facing a steady circular yellow or yellow arrow signal, unless otherwise directed by a pedestrian control signal, are thereby advised that there is insufficient time to cross the roadway before a red indication is shown, and no pedestrian may start to cross the roadway at that time.
(C) Steady red indication:
(1) Vehicular traffic facing a steady circular red signal alone shall stop at clearly marked stop line, but if none, before entering the crosswalk on the near side of the intersection, or if none, then before entering the intersection and shall remain standing until an indication to proceed is shown except as provided in division (C)(2);
(2) Except when a sign is in place prohibiting such a turn, vehicular traffic facing a steady red signal, after coming to a complete stop, may cautiously enter the intersection to:
(a) Make a right turn; or
(b) Make a left turn if turning from the left lane of a one-way street into another one-way street with the flow of traffic; but such vehicular traffic shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic using the intersection; and
(3) Unless otherwise directed by a pedestrian-control signal under IC 9-4-1-36, pedestrians facing a steady circular red signal alone shall not enter the roadway.
(D) No indication or conflicting indications:
(1) Vehicular traffic facing an intersection having a signal that displays no indication or conflicting indications, where no other control is present, shall stop before entering the intersection; and
(2) After stopping, vehicular traffic may proceed with caution through the intersection and shall yield the right-of-way to traffic within the intersection, or approaching so closely as to constitute an immediate hazard.
(E) Nonintersection installations: the provisions of this section apply to traffic-control signals located at a place other than an intersection except those provisions which by their nature have no application. Any stop required under this division must be made at the signal except when the signal is supplemented by a sign or pavement marking indicating where the stop must be made.
