What is the seating requirement for passengers on a school bus?

Passengers on a school bus are required to be seated at all times to ensure their safety. This requirement is crucial because it minimizes the risk of injury during sudden stops or accidents. By remaining seated, students are less likely to be thrown from their seats, which can lead to serious injuries. Moreover, school buses are designed with specific safety features, such as compartmentalization, which rely on passengers being seated properly.

The other options suggest behaviors that could compromise safety. Standing or moving freely while the bus is in motion increases the risk of falls and injuries. Additionally, while some school buses may not have seat belts, the regulation for passengers to be seated reflects a focus on maintaining a secure and safe environment during transportation.
