   (B)   It is prima facie lawful, in the absence of a lower limit declared established pursuant to this section by the Director of Transportation or local authorities, for the operator of a motor vehicle to operate the same at a speed not exceeding the following:
      (1)   (a)   Twenty miles per hour in school zones during school recess and while children are going to or leaving school during the opening or closing hours, and when 20 miles per hour school speed limit signs are erected, except that on controlled-access highways and expressways, if the right-of-way line fence has been erected without pedestrian opening, the speed shall be governed by divisions (B)(10) and (B)(11) of this section, and on freeways, if the right-of-way line fence has been erected without pedestrian opening, the speed shall be governed by division (B)(7) of this section. The end of every school zone may be marked by a sign indicating the end of the zone. Nothing in this section or in the Manual and Specifications for a Uniform System of Traffic-Control Devices shall be construed to require school zones to be indicated by signs equipped with flashing or other lights, or giving other special notice of the hours in which the school zone speed limit is in effect.
         (b)   As used in this section, SCHOOL means any school chartered under R.C. § 3301.16 and any nonchartered school that during the preceding year filed with the Department of Education in compliance with O.A.C. § 3301-35-08, a copy of the school’s report for the parents of the school’s pupils certifying that the school meets state minimum standards for nonchartered, nontax-supported schools and presents evidence of this filing to the jurisdiction from which it is requesting the establishment of a school zone.  SCHOOL also includes a special elementary school that in writing requests the County Engineer to create a school zone at the location of the school. Upon receipt of such written request, the County Engineer shall create a school zone at that location by erecting appropriate signs.

Upon request from local authorities for streets and highways under their jurisdiction and that portion of a state highway under the jurisdiction of the Director of Transportation or a request from a County Engineer in the case of a school zone for a special elementary school, the Director may extend the traditional school zone boundaries. The distances in divisions (B)(1)(c)1. through (B)(1)(c)1.3. below shall not exceed 300 feet per approach per direction, and are bounded by whichever of the following distances or combination thereof the Director approves as most appropriate:

            2.   The distance encompassed by projecting the school property lines intersecting the fronting highway and extending a distance of 300 feet on each approach direction;
            3.   The distance encompassed by the special marking of the pavement for a principal school pupil crosswalk plus a distance of 300 feet on each approach direction of the highway.
         (d)   Nothing in this section shall be construed to invalidate the Director’s initial action on August 9, 1976, establishing all school zones at the traditional school zone boundaries defined by projecting school property lines, except when those boundaries are extended as provided in divisions (B)(1)(a) and (B)(1)(c) of this section.
         (e)   As used in this division, CROSSWALK has the meaning given that term in R.C. § 4511.01(LL)(2).
