1. Every school bus except private passenger vehicles used as school buses shall be constructed and equipped to meet safety standards prescribed in rules adopted by the state board of education. Such rules shall conform to safety standards set forth in federal laws and regulations and shall conform, insofar as practicable, to the minimum standards for school buses recommended by the national conference on school transportation administered by the national commission on safety education and published by the national education association.
2. Rules prescribed for school buses shall provide standards for structural strength, materials, and insulation of the school bus body; color; seat and aisle arrangement; dimension and construction of service door; control of the front door or doors; emergency door and its location and construction; windows; roof ventilators; heaters; location, filling, and draining of the fuel tank; bumpers and how they shall be attached to the bus; lettering and identification of the bus; stop signal arm; warning lights and flashing lights.
3. a. The rules prescribed for school buses shall include special rules for passenger automobiles, and other vehicles designed to carry ten or fewer persons, including the driver, when used as school buses.
b. The rules shall allow pickups designed to carry nine passengers or less, including the driver, and weighing ten thousand pounds or less, to be used as school buses if the pickup does not carry more passengers than there are safety belts or safety harnesses in the pickup as installed by the manufacturer and if the pickup is not operated while any passenger is present in the bed of the pickup. The operator of the pickup shall comply with the qualification, licensing, and instruction requirements set forth in sections 321.375 and 321.376, other than the requirement to obtain a commercial driver’s license. However, the rules shall allow the board of directors of a school district to prohibit the use of pickups as school buses by the school district.
