313.03  TRAFFIC SIGNAL INDICATIONS.
   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)   A.   Vehicular traffic facing a steady circular red signal indication, unless entering the intersection to make another movement permitted by another signal indication, shall stop at a clearly marked stop line; but if there is no stop line, traffic shall stop before entering the crosswalk on the near side of the intersection; or if there is no crosswalk, before then before entering the intersection; and shall remain stopped until a signal indication to proceed is displayed except as provided in subsections (c)(1), (2) and (3) of this section.
         B.   Except when a traffic control device is in place prohibiting a turn on red or a steady red arrow signal indication is displayed, vehicular traffic facing a steady circular red signal indication is permitted, after stopping, to enter the intersection to turn right, or to turn left from a one-way street into a one-way street.  The right to proceed with the turn shall be subject to the provisions that are applicable after making a stop at a stop sign.
      (2)   A.   Vehicular traffic facing a steady red arrow signal indication shall not enter the intersection to make the movement indicated by the arrow and, unless entering the intersection to make another movement permitted by another signal indication, shall stop at a clearly marked stop line; but if there is no stop line, 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 stopped until a signal indication or other traffic control device permitting the movement indicated by such red arrow is displayed.
         B.   When a traffic control device is in place permitting a turn on a steady red arrow signal indication, vehicular traffic facing a steady red arrow indication is permitted, after stopping, to enter the intersection to turn right or to turn left from a one-way street into a one-way street.  The right to proceed with the turn shall be limited to the direction indicated by the arrow, and shall be subject to the provisions that are applicable after making a stop at a stop sign.
      (3)   Unless otherwise directed by a pedestrian signal indication as provided in Section 313.05 or other traffic control device, pedestrians facing a steady circular red or steady red arrow signal indication shall not enter the roadway.
      (4)   Local authorities by ordinance, or the Director of Transportation on State highways, may prohibit a right or a left turn against a steady red signal at any intersection, which shall be effective when signs giving notice thereof are posted at the intersection.
   (d)   Flashing Green Signal Indication.  A flashing green signal indication has no meaning and shall not be used.
   (e)   Flashing Yellow Signal Indication:
      (1)   A.   Vehicular traffic, on an approach to an intersection, facing a flashing circular yellow signal indication, is permitted to cautiously enter the intersection to proceed straight through or turn right or left or make a u-turn movement except as such movement is modified by lane-use signs, turn prohibition signs, lane markings, roadway design, separate turn signal indications, or other traffic control devices.  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 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)   A.   Vehicular traffic, on an approach to an intersection, facing a flashing yellow 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 other such movement as is permitted by other signal indications displayed at the same time.  Such vehicular traffic, including vehicles turning right or left or making a u-turn, 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 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.
      (3)   Pedestrians facing any flashing yellow signal indication at an intersection, unless otherwise directed by a pedestrian signal indication or other traffic control device, are permitted to proceed across the roadway within any marked or unmarked associated crosswalk.  Pedestrians shall yield the right-of-way to vehicles lawfully within the intersection at the time that the flashing yellow signal indication is first displayed.
      (4)   When a flashing circular yellow signal indication is displayed as a beacon to supplement another traffic control device, road users are notified that there is a need to pay additional attention to the message contained thereon or that the regulatory or warning requirements of the other traffic control device, which might not be applicable at all times, are currently applicable.
   (f)   Flashing Red Signal Indication:
      (1)   Vehicular traffic, on an approach to an intersection, facing a flashing circular red signal indication, shall stop at a clearly marked stop line; but if there is no stop line, before entering the crosswalk on the near side of the intersection; or if there is no crosswalk, at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway before entering the intersection.  The right to proceed shall be subject to the provisions that are applicable after making a stop at a stop sign.
      (2)   Pedestrians facing any flashing red signal indication at an intersection, unless otherwise directed by a pedestrian signal indication or other traffic control device, are permitted to proceed across the roadway within any marked or unmarked associated crosswalk.  Pedestrians shall yield the right-of-way to vehicles lawfully within the intersection at the time that the flashing red signal indication is first displayed.
      (3)   When a flashing circular red signal indication is displayed as a beacon to supplement another traffic control device, road users are notified that there is a need to pay additional attention to the message contained thereon or that the regulatory requirements of the other traffic control device, which might not be applicable at all times, are currently applicable.  Use of this signal indication shall be limited to supplementing stop, do not enter, or wrong way signs, and to applications where compliance with the supplemented traffic control device requires a stop at a designated point.
   (g)   General Application: 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.
   (h)   Exception.  This section does not apply at railroad grade crossings.  Conduct of drivers of vehicles approaching railroad grade crossings shall be governed by Ohio R.C. 4511.61 and 4511.62.  (ORC 4511.13)
