(a) When the Traffic Committee constituted under 19 V.S.A. § 1(24) determines, on the basis of an engineering and traffic investigation that shall take into account, if applicable, safe speeds within school zones (or safe speeds within 200 feet of school district-operated prekindergarten program facilities owned or leased by a school district) when children are traveling to or from such schools or facilities, that a maximum speed limit established by this chapter is greater or less than is reasonable or safe under conditions found to exist at any place or upon any part of a State highway, including the Dwight D. Eisenhower National System of Interstate and Defense Highways, it may determine and declare a reasonable and safe limit which is effective when appropriate signs stating the limit are erected. This limit may be declared to be effective at all times or at times indicated upon the signs; and differing limits may be established for different times of day, different types of vehicles, varying weather conditions, or based on other factors bearing on safe speeds, which are effective when posted upon appropriate fixed or alterable signs.

(b) When establishing a maximum speed limit on a State highway contiguous to a school, the Traffic Committee shall consider, along with the engineering and traffic investigation, data collected for the purpose of promulgating a school travel plan under the Vermont Safe Routes to School Program.
