(A) No vehicle shall turn at any intersection where an automatic signal system is in operation, except when such signal system is displaying a green light; provided, vehicles may turn on a red signal when in compliance with the provisions of this article governing such turns. No vehicle shall be turned so as to proceed in the opposite direction at any intersection where an automatic signal system is in operation.
(2005 Code, § 5-201)
(B) (1) Automatic stop lights or signals shall be established at such places as designated by ordinance as shown on the Traffic-Control Map of the Mayor and City Council. At each intersection where an automatic signal system is in operation, all vehicular and pedestrian traffic crossing such street intersection shall be governed by such automatic signal system. Vehicular traffic facing a green signal may proceed straight through or turn right or left unless a sign at such place prohibits either such turn, but 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 such signal is exhibited.
(2) 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, and 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, pedestrians facing any green arrow may proceed across the roadway within any marked or unmarked crosswalk.
(4) 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 shall not enter the intersection and, upon display of a steady yellow signal, vehicular traffic shall stop before entering the nearest crosswalk at the intersection, but, if such stop cannot be made in safety, a vehicle may be driven cautiously through the intersection.
(5) 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 no pedestrian shall then start to cross the roadway.
(6) Vehicular traffic facing a steady red signal alone shall stop at a clearly-marked stop line, but, if there is no such line, then before entering the crosswalk on the near side of the intersection, or if there is no crosswalk then before entering the intersection and shall remain standing until an indication to proceed is shown, except as provided in § 5-202 of this article.
(7) It shall be unlawful for any person to violate any such signal.
