313.02  THROUGH STREETS; STOP AND YIELD RIGHT-OF-WAY
        SIGNS.
   (a)   All State routes are hereby designated as through streets or highways, provided that stop signs, yield signs or traffic control signals shall be erected at all intersections with such through streets or highways, except as otherwise provided in this section.  Where two or more State routes that are through streets or highways intersect and no traffic control signal is in operation, stop signs or yield signs shall be erected at one or more entrances thereto by the Ohio Department of Transportation, except as otherwise provided in this section.
   Whenever the Ohio Director of Transportation determines on the basis of an engineering and traffic investigation that stop signs are necessary to stop traffic on a through highway for safe and efficient operation, nothing in this section shall be construed to prevent such installations.  When circumstances warrant, the Director also may omit stop signs on roadways intersecting through highways under his jurisdiction.  Before the Director either installs or removes a stop sign under this paragraph, he shall give notice, in writing, of that proposed action to the Municipality at least thirty days before installing or removing the stop sign.
   (b)   Other streets or highways or portions thereof, are hereby designated through streets or highways, if they are within the Municipality, if they have a continuous length of more than one mile between the limits of such street or highway or portion thereof, and if they have "stop" or "yield" signs or traffic control signals at the entrances of the majority of intersecting streets or highways.  For purposes of this section, the limits of such street or highway or portion thereof, shall be a municipal corporation line, the physical terminus of the street or highway or any point on such street or highway at which vehicular traffic thereon is required by regulatory signs to stop or yield to traffic on the intersecting street, provided that in residence districts the Municipality may by ordinance designate such street or highway, or portion thereof, not to be a through highway and thereafter the affected residence district shall be indicated by official traffic control devices.  Where two or more streets or highways designated under this subsection (b) intersect and no traffic control signal is in operation, stop signs or yield signs shall be erected at one or more entrances thereto by the Ohio Department of Transportation or by Council or the authorized local authority, except as otherwise provided in this section.
   (c)   Stop signs need not be erected at intersections so constructed as to permit traffic to safely enter a through street or highway without coming to a stop.  Signs shall be erected at such intersections indicating that the operator of a vehicle shall yield the right of way to or merge with all traffic proceeding on the through street or highway.
   (d)   Council or the authorized local authority may designate additional through streets or highways and shall erect stop signs, yield signs or traffic control signals at all streets and highways intersecting such through streets or highways, or may designate any intersection as a stop or yield intersection and shall erect like signs at one or more entrances to such intersection.  (ORC 4511.65)
