What is the proper action for a driver when approaching a school bus with its stop sign extended?

When a driver approaches a school bus with its stop sign extended, the correct action is to stop until the bus retracts its stop sign. This is a critical safety measure designed to protect children who may be boarding or disembarking from the bus. The extended stop sign serves as a clear indicator that children are getting on or off the bus, and it is unlawful to pass the bus in this situation. Stopping ensures the safety of those children by providing them with a secure environment to enter or exit the bus without the added risk of passing vehicles.

Understanding the importance of this rule is paramount, as it emphasizes the responsibility drivers have to watch out for vulnerable road users, particularly children. It also instills the idea that the designated school bus stop signals are serious and must be adhered to strictly to avoid accidents and ensure the safety of all.
