(A) No person shall drive a motor vehicle at a speed in excess of 20 mph while passing a school zone or while traveling upon any public thoroughfare on or across which children pass along to and from school during school days when school children are present.
(B) This section shall not be applicable unless appropriate signs are posted upon streets and highways where the school zone located. Such signs shall give proper due warning that a school zone is being approached and shall indicate the school zone and the maximum speed limit in effect during school days when school children are present. Nothing in this title shall prohibit the use of electronic speed-detecting devices within 500 feet of signs within a special school speed zone indicating such zone, as defined in this section, nor shall evidence obtained thereby be inadmissible in any prosecution for speeding provided the use of such device shall apply only to the enforcement of the speed limit in such special school speed zone. The school zones are set forth in Ch. 77, Sch. IX.
