What action is required when approaching a school bus with its stop sign extended?

When approaching a school bus that has its stop sign extended, the required action is to stop and wait until the sign is retracted. This is important for ensuring the safety of children entering or exiting the bus. The extended stop sign and flashing lights indicate that children may be crossing the road and it is crucial for drivers to remain stopped until the bus signals that it is safe to proceed.

This rule is in place to provide a safe environment for children, who may not always be aware of traffic around them. By stopping, you are allowing time for any children who may be loading or unloading from the bus to do so without the risk of being struck by an oncoming vehicle. It is a fundamental part of traffic laws surrounding school buses, which are designed to protect vulnerable road users.
