Final answer:
Passengers on a school bus are generally required to be seated for safety reasons while the bus is in motion.
Step-by-step explanation:
Passengers on a school bus have specific safety protocols that they need to follow. In the context of a school bus environment, it is generally required that passengers remain seated while the bus is in motion to ensure safety. Bus safety rules typically do not allow passengers to stand or move from seat to seat because this can create a risk of injury, especially if the bus needs to make sudden stops or maneuvers. This requirement aligns with wider public safety rules for transit vehicles and supports the safe transportation of students to and from school. Although there may be exceptions depending on the specific bus or transit authority regulations, the safety norm is to remain seated. There are no age restrictions on who can ride the bus based on this information. The intent is to protect all passengers, regardless of age.
