I don't see a (B)(2) in there. But the (b) seems to all be school zone related.
333.03 MAXIMUM SPEED LIMITS; ASSURED CLEAR DISTANCE AHEAD.
(a) No person shall operate a motor vehicle at a speed greater or less than is reasonable or proper, having due regard to the traffic, surface and width of the street or highway and any other conditions, and no person shall drive any motor vehicle in and upon any street or highway at a greater speed than will permit the person to bring it to a stop within the assured clear distance ahead.
(b) It is prima-facie lawful, in the absence of a lower limit declared or established pursuant to Ohio R.C. 4511.21 by the Ohio Director of Transportation or Council, 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 twenty 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 subsection (b)(4) hereof and on freeways, if the right-of-way line fence has been erected without pedestrian opening, the speed shall be governed by subsection (b)(7) hereof. 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 Ohio R.C. 3301.16 and any nonchartered school that during the preceding year filed with the Department of Education in compliance with rule 3301-35-08 of the Ohio Administrative Code, a copy of the school's report for the parents of the school's pupils certifying that the school meets Ohio 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.
C. As used in this section, "school zone" means that portion of a street or highway passing a school fronting upon the street or highway that is encompassed by projecting the school property lines to the fronting street or highway. Upon request from the Municipality for streets and highways under its jurisdiction, the Ohio Director of Transportation may extend the traditional school zone boundaries. The distances in subsections (b)(1)C.1. to 3. hereof shall not exceed 300 feet per approach per direction and are bounded by whichever of the following distances or combinations thereof the Director approves as most appropriate:
1. The distance encompassed by projecting the school building lines normal to the fronting highway and extending a distance of 300 feet on each approach direction;
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 highway;
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 subsections (b)(1)A. and C. hereof.
D. As used in this subsection, "crosswalk" has the meaning given that term in Section
301.09. The Director may, upon request by resolution of Council, and upon submission by the Municipality of such engineering, traffic and other information as the Director considers necessary, designate a school zone on any portion of a State route lying within the Municipality that includes a crosswalk customarily used by children going to or leaving a school during recess and opening and closing hours, whenever the distance, as measured in a straight line, from the school property line nearest the crosswalk to the nearest point of the crosswalk is no more than 1,320 feet. Such a school zone shall include the distance encompassed by the crosswalk and extending 300 feet on each approach direction of the State route;
