Modifies provisions relating to school buses

This bill updates state laws to clarify how school buses are defined and who is responsible for managing access to them. It requires school boards to create written policies that specify when individuals can enter or operate a school bus, ensuring such actions are either approved by the board or included in the district's official rules. The legislation also establishes that unauthorized entry or operation of a school bus is a class A misdemeanor. Additionally, the bill defines a school bus as any vehicle designed to carry more than ten passengers used for transporting students, while excluding regular public transit or charter buses not on a specific school route. These changes directly affect school districts, their transportation staff, and the general public by setting clearer boundaries and penalties regarding school bus usage.
