The school board of a school district may levy taxes for a school safety plan fund, subject to the limitations in section 57-15-14.2, when authorized to do so by a majority of the qualified electors of a school district voting upon the question at any regular or special school district election. The ballot must specify the number of mills proposed for approval and the number of years for which that approval is to apply. Approval or reauthorization by electors of levy authority under this section may not be effective for more than five taxable years.
