Under what circumstance may a school bus tow another vehicle?

A school bus is prohibited from towing another vehicle under any circumstance, ensuring the safety of students and the integrity of the bus operations. Towing could pose significant safety risks, as school buses are not designed for towing and might affect their braking and handling. Additionally, school buses have a specific purpose of transporting students and should not engage in activities like towing, which can divert the driver's attention or create hazardous situations on the road.

While emergency situations, maintenance, or requests for assistance may seem like logical contexts for towing, the primary concern is always the safety and secure transport of students. Allowing a bus to tow could lead to complications that outweigh the reasons for doing so, hence the strict guideline that school buses should never tow any other vehicles.
