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.

F. 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;
