What is the maximum speed limit for school buses on numbered highways that have passed a commercial motor vehicle inspection?

The correct answer is 65 mph because this speed limit applies to school buses operating on numbered highways, provided these highways have passed a commercial motor vehicle inspection. This maximum speed limit acknowledges that school buses, which transport children, are allowed to operate at similar speeds as other larger vehicles that are inspected for safety on highways.

When considering the context of different speed limits, it's important to recognize that standard speed limits for school zones or other areas may be lower due to the safety of children. However, once a school bus is on a properly maintained and inspected numbered highway, it is permitted to travel at this higher maximum speed, reflecting compliance with regulations intended to facilitate the efficient movement of commercial vehicles and buses on major roadways.

This regulation is designed to ensure that school buses can operate safely and efficiently alongside other traffic while adhering to safety standards set forth for commercial vehicles.
