313.03 TRAFFIC CONTROL SIGNAL TERMS AND LIGHTS.
   Highway traffic signal indications for vehicles, and pedestrians shall have the following meanings:
   (a)   Steady Green Signal Indication:
      (1)   A.   Vehicular traffic facing a circular green signal indication is permitted to proceed straight through or turn right or left, or make a u-turn movement except as such movement is modified by a lane- use sign, turn prohibition sign, lane marking, roadway design, separate turn signal indication, or other traffic control device. Such vehicular traffic, including vehicles turning right or left or making a u-turn movement, shall yield the right-of-way to both of the following:
            1.   Pedestrians lawfully within an associated crosswalk;
            2.   Other vehicles lawfully within the intersection.
         B.   In addition, vehicular traffic turning left or making a u-turn movement to the left shall yield the right-of-way to other vehicles approaching from the opposite direction so closely as to constitute an immediate hazard during the time when such turning vehicle is moving across or within the intersection.
      (2)   Vehicular traffic facing a green arrow signal indication, displayed alone or in combination with another signal indication, is permitted to cautiously enter the intersection only to make the movement indicated by such arrow, or such other movement as is permitted by other indications displayed at the same time. Such vehicular traffic, including vehicles turning right or left or making a u-turn movement, shall yield the right-of-way to both of the following:
         A.   Pedestrians lawfully within an associated crosswalk.
         B.   Other traffic lawfully using the intersection.
      (3)   A.   Unless otherwise directed by a pedestrian signal indication, as provided in Section 313.05 , pedestrians facing a circular green signal indication are permitted to proceed across the roadway within any marked or unmarked associated crosswalk. The pedestrian shall yield the right-of-way to vehicles lawfully within the intersection or so close as to create an immediate hazard at the time that the green signal indication is first displayed.
         B.   Pedestrians facing a green arrow signal indication, unless otherwise directed by a pedestrian signal indication or other traffic control device, shall not cross the roadway.
   (b)   Steady Yellow Signal Indication:
      (1)   Vehicular traffic facing a steady circular yellow signal indication is thereby warned that the related green movement or the related flashing arrow movement is being terminated or that a steady red signal indication will be exhibited immediately thereafter when vehicular traffic shall not enter the intersection. The provisions governing vehicular operation under the movement being terminated shall continue to apply while the steady circular yellow signal indication is displayed.
      (2)   Vehicular traffic facing a steady yellow arrow signal indication is thereby warned that the related green arrow movement or the related flashing arrow movement is being terminated. The provisions governing vehicular operation under the movement being terminated shall continue to apply while the steady yellow arrow signal indication is displayed.
      (3)   Pedestrians facing a steady circular yellow or yellow arrow signal indication, unless otherwise directed by a pedestrian signal indication as provided in Section 313.05 or other traffic control device, shall not start to cross the roadway.
   (c)   Steady Red Signal Indication:
      (1)   Vehicular traffic facing a steady 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 subsections (c)(2) and (3) hereof.
      (2)   Unless a sign is in place prohibiting a right turn as provided in subsection (c)(5) hereof, vehicular traffic facing a steady red signal may cautiously enter the intersection to make a right turn after stopping as required by subsection (c)(1) hereof. Such vehicular traffic shall yield the right of way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersetion.
      (3)   Unless a sign is in place prohibiting a left turn as provided in subsection (c)(5) hereof, vehicular traffic facing a steady red signal on a one-way street that intersects another one-way street on which traffic moves to the left may cautiously enter the intersection to make a left turn into the one-way street after stopping as required by subsection (c)(1) hereof, and yielding the right of way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.
