If traffic is controlled by traffic control signals exhibiting different colored lights or colored lighted arrows, successively one at a time or in combination, except for special pedestrian signals carrying a word or legend, those signals apply to drivers of vehicles and pedestrians as follows:

1) Green indication;

a) Vehicular traffic facing a circular green signal may proceed straight through or turn right or left unless a sign at that place prohibits either turn. But vehicular traffic, including vehicles turning left or right, must yield the right-of-way to other vehicles and pedestrians lawfully within the intersection or 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 indication, may cautiously enter the intersection only to make the movement indicated by the arrow or such other movement as is permitted by other indications shown at the same time. Vehicular traffic must yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.

c) 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.

2) Steady yellow indication;

a) Vehicular traffic facing a steady yellow signal is thereby warned that the related green movement is being terminated or that a red indication will be exhibited immediately thereafter when vehicular traffic may not enter the intersection.

b) Pedestrians facing a steady yellow 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 not to cross the roadway.

3) Steady red indication;

a) Vehicular traffic facing a steady red signal alone must stop at a 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 must remain standing until an indication to proceed is shown, except as provided in the following paragraph.

b) Except when a sign is in place prohibiting a turn, vehicular traffic facing a 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 (a). Such vehicular traffic must yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.

c) Unless otherwise directed by a pedestrian control signal, pedestrians facing a steady red signal alone may not enter the roadway.

4) If an official traffic control signal is erected and maintained at a place other than an intersection, the foregoing provisions apply, except as to provisions which by their nature can have no application. Any stop required must be made at a sign.
