What is a critical factor in the design of school bus body systems?

Weight distribution and balance are critical factors in the design of school bus body systems because they directly impact the safety and stability of the vehicle. Proper weight distribution ensures that the bus maintains a low center of gravity, which is crucial for preventing rollovers, especially during sharp turns or abrupt stops. Additionally, a well-balanced bus can improve handling, reduce tire wear, and enhance overall performance.

While cost of manufacturing, interior styling and comfort, and branding and marketing may influence the vehicle's appeal or sales potential, they do not have the same fundamental impact on the operational safety and structural integrity of the bus. Safety is paramount in school bus design, and achieving optimal weight distribution is a key aspect to ensuring that the vehicle can transport students safely.
