Which of the following is NOT allowed while driving a school bus?

Using a handheld mobile device while driving a school bus is expressly prohibited due to the high level of distraction it presents. The primary responsibility of a school bus driver is to ensure the safety of the students on board, and operating a mobile device divides attention, significantly increasing the risk of accidents. Safety regulations are designed to minimize distractions, hence the emphasis on not using handheld devices.

Listening to music through headphones and eating while driving also create distractions, making it difficult for drivers to focus completely on the road and the behavior of their passengers. These actions could impair the driver’s ability to respond quickly to any unexpected situations that may arise during the drive.

The option stating "All of the above" encompasses all these distractions, indicating that none of these activities are allowed while driving a school bus, reinforcing the principle that the driver's primary focus must be on operating the vehicle and ensuring the safety of the students.
