Which vehicle is characterized as a school bus?

Answer: B — vehicle designed for transporting more than 15 passengers to and from school

The correct classification of a school bus is grounded in its primary function and passenger capacity. A vehicle designed specifically for transporting more than 15 passengers to and from school encompasses the core characteristics that define a school bus. This definition aligns with safety regulations and transportation codes aimed at ensuring that students have a secure means of travel to educational institutions. Options that suggest a bus for public transport of school staff, limit the passenger age to only high school students, or indicate a vehicle meant for carrying goods simply do not meet the specific criteria set for a school bus. School buses must primarily serve the purpose of transporting students, which is integral to the intent behind their design and construction. Therefore, recognizing the significance of the passenger capacity and the dedicated role in education transportation highlights why this choice is the unequivocal standard for identifying a school bus.
