§47-11-202.
   
   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 shall
   be used, except for special pedestrian signals carrying a word legend,
   and said lights shall indicate and apply to drivers of vehicles and
   pedestrians as follows:
   
   1. Green indication:
   
   a. Vehicular traffic facing a circular green signal, except when
   prohibited under Section 11-1302 of this title, may proceed straight
   through or turn right or left unless a sign at such place prohibits
   either such turn. But vehicular 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.
   
   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 such arrow, or
   such other movement as is permitted by other indications shown at the
   same time. Such vehicular traffic shall 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, as
   provided in Section 11-203 of this title, 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 circular yellow or yellow arrow
   signal is thereby warned that the related green movement is being
   terminated or that a red indication will be exhibited immediately
   thereafter.
   
   b. Pedestrians facing a steady circular yellow or yellow arrow signal,
   unless otherwise directed by a pedestrian control signal as provided
   in Section 11-203 of this title, 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.
   
   3. Steady red indication:
   
   a. Vehicular traffic facing a steady circular red signal alone shall
   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 shall remain standing until an
   indication to proceed is shown except as provided in paragraph 3b of
   this section.
   
   b. 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 paragraph 3a 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.
   
   c. In order to prohibit right turns or left turns as prescribed in
   paragraph 3b of this section on the red signal after the required
   stop, a municipality must erect clear, concise signs informing drivers
   that such turns are prohibited. The Highway Department shall specify
   the design of the sign to be used for this purpose, and it shall be
   used uniformly throughout the state.
   
   d. Unless otherwise directed by a pedestrian control signal as
   provided in Section 11-203 of this title, pedestrians facing a steady
   circular red signal alone shall not enter the roadway.
   
   In the event an official traffic control signal is erected and
   maintained at a place other than an intersection, the provisions of
   this section shall be 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
   shall be made, but in the absence of any such sign or marking the stop
   shall be made at the signal.
