What is the primary concern when towing a disabled bus with riders aboard?

The primary concern when towing a disabled bus with riders aboard is the risk for riders if they exit the bus. This concern arises because the passengers are at risk of being in a dangerous situation if the bus is not secured or if there's traffic nearby. In scenarios where a bus is being towed, stabilization is critical to ensure that passengers remain safe, as moving or exiting the bus can lead to accidents or injuries, especially if the environment is busy with vehicular traffic.

It's essential for the safety of the passengers to keep them inside the bus while it is being towed, thereby preventing potential chaos or harm that could occur during the towing process. Ensuring that passengers remain in a secure environment until the bus is safely towed to a secure location is paramount to mitigating risks. Other concerns, such as the distance to be towed, the type of tow vehicle, and the time taken to complete the tow, may also be important to consider in a broader operational context, but the immediate safety of the passengers is the top priority.
