(A) Traffic-control signals exhibiting the words “go”, “caution” or “stop” or exhibiting different colored lights successively one at a time, or with arrows, shall show the following colors only and shall apply to drivers of vehicles and pedestrians as follows.
(1) Green alone or “go”.
(a) Vehicular traffic facing the signal may proceed straight through or turn right or left unless a sign at such place prohibits 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) Pedestrians facing the signal may proceed across the roadway within any marked or unmarked crosswalk.
(2) Steady yellow alone or “caution”.
(a) Vehicular traffic facing the signal is thereby warned that the red or “stop” signal will be exhibited immediately thereafter and such vehicular traffic shall not enter or be crossing the intersection when the red or “stop” signal is exhibited.
(b) Pedestrians facing such signal shall not enter the roadway.
(3) Steady red alone or “stop”.
(a) Vehicular traffic facing the signal shall stop before entering the crosswalk on the near side of the intersection or, if none, then before entering the intersection and shall remain standing until green or “go” is shown alone. A right turn on a red signal shall be permitted at all intersections within the city, provided that the prospective turning car comes to a full and complete stop before turning and that the turning car yields the right-of-way to pedestrians and cross traffic traveling in accordance with their traffic signal. However, the turn will not endanger other traffic lawfully using said intersection. A right turn on red shall be permitted at all intersections, except those clearly marked by a “no turns on red” sign, which may be erected by the city at intersections which the city decides require no right turns on red in the interest of traffic safety.
(b) Pedestrians facing such signal shall not enter the roadway.
(4) Steady red with green arrow.
(a) Vehicular traffic facing such signal may cautiously enter the intersection only to make the movement indicated by such arrow, but shall yield the right-of-way to pedestrians lawfully within a crosswalk and to other traffic lawfully using the intersection.
(b) Pedestrians facing such signal shall not enter the roadway.
(B) 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 a vehicle length short of the signal.
