Amends GS 115C-243. Amends the caption to read "Use of school buses by senior citizen groups, government entities, and nonprofits." Authorizes local boards of education to further enter into agreements with any tax-exempt nonprofit corporation to provide the use of school buses for transportation service. Authorizes use by any authorized entity on legal holidays, weekends, or breaks between school years. Requires the schedule of charges for use under this statute to include a charge by the hour and by the mile which will cover all costs both fixed and variable, including depreciation, gasoline, fuel, labor, maintenance, wages, and insurance (currently, these are set in a schedule by the State Board of Education, and the local board's schedule may not differ except with regard to charges to cover wages). Directs the local board of education to report the schedule to the Superintendent of Public Instruction each year. Authorizes buses used under this section to travel anywhere in the state. Makes conforming changes.
