§1022. Traffic-control signals.
(a) 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 and yellow may be used, except for special pedestrian signals carrying a word legend, and the signals shall indicate and apply to drivers and pedestrians as follows:
(1) Green signal
(A) Vehicular traffic facing a circular green signal may proceed straight through or turn right or left unless a sign prohibits either turn. Vehicular traffic, including vehicles turning right or left, shall yield the right of way to other vehicles or to pedestrians lawfully within the intersection or on an adjacent crosswalk at the time the signal is exhibited.
(B) Vehicular traffic facing a green arrow signal, shown alone or in combination with another signal, may cautiously enter the intersection only to make the movement indicated by the arrow, or such other movement as is permitted by other signals shown at the same time. Vehicular traffic shall yield the right of way to pedestrians lawfully within an adjacent crosswalk or to other traffic lawfully using the intersection.
(C) Unless otherwise directed by a pedestrian-control signal, as provided in section 1023 of this title, pedestrians facing a green signal may proceed across the roadway within any marked or unmarked crosswalk, but not when the sole green signal is a turn arrow.
(b) Steady yellow signal
(1) Vehicular traffic facing a steady yellow signal is thereby warned that the related green signal is being terminated or that a red signal will be exhibited immediately thereafter, when vehicular traffic shall not enter the intersection.
(2) Pedestrians facing a steady yellow signal, unless otherwise directed by a pedestrian-control signal as provided in section 1023 of this title, are advised that there is insufficient time to cross the roadway before a red signal is shown, and no pedestrian shall then start to cross the roadway.
(c) Steady red signal
(1) Vehicular traffic facing a steady circular red signal alone shall stop at a clearly marked stop line, but if none, shall stop before entering the crosswalk on the near side of the intersection.
(2) Except when a sign is in place prohibiting a turn, vehicular traffic facing any steady red signal may cautiously enter the intersection to turn right, or to turn left from a one way street into a one way street, after stopping as required by subdivision (c)(1) of this section. Such vehicular traffic shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.
(3) Unless otherwise directed by a pedestrian-control signal as provided in section 1023 of this title, pedestrians facing a steady red signal alone shall not enter the roadway.
(d) If an official traffic-control signal is erected and maintained at a place other than an intersection, this section is 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 pavement indicating where the stop is to be made, but in the absence of any sign or marking the stop shall be made at the signal.
