Which action is required by passengers while on the bus to the aircraft?

Passengers are required to remain seated while the bus is in motion to ensure safety during transit to the aircraft. This protocol minimizes the risk of injury in the event of sudden stops or sharp turns. When everyone remains seated, it also allows the driver to maintain focus on driving without the distraction of passengers moving around.

Other actions, such as keeping personal items visible, standing for visibility, or using electronic devices freely, could introduce risks. For example, standing while the bus is in motion could lead to falls or injuries, which is why remaining seated is the standard safety procedure.
