Section 7B of chapter 90 of the General Laws, as appearing in the 1986 Official Edition, is hereby amended by striking out clause (11) and inserting in place thereof the following clause:-
(11) Type I and Type II school buses purchased, leased or contracted after January first, nineteen hundred and eighty-nine for use in the commonwealth shall be equipped with an octagonal stop warning device incorporating alternately flashing red lights approved by the registrar and mounted in accordance with the registrar's regulations upon the left side and shall only be activated to extend outward when picking up or discharging school pupils. All other Type I and Type II school buses shall be so equipped with said device no later than January first, nineteen hundred and ninety-four. Such device, when fully extended, shall not protrude more than twenty-two inches outward from the left side of the body. The use of such device shall not be construed as increasing the width of such bus beyond the limits prescribed by section nineteen. The registrar shall promulgate rules and regulations providing for a certification process for the installation of said device.
