What must all vehicles do when a school bus is picking up or setting down passengers?

When a school bus is picking up or setting down passengers, the appropriate action for all vehicles is to stop until the bus has finished its operation. This rule is in place to ensure the safety of children who may be boarding or disembarking from the bus. The requirement to stop helps to prevent accidents and allows children to cross the road safely without the risk of vehicles passing by at high speeds.

The law emphasizes the importance of vigilance around school buses, as children can be unpredictable, and their presence around traffic requires heightened caution. Compliance with this rule reflects a community's commitment to child safety and responsible driving practices.
