What must you do when a school bus has its lights flashing and a stop sign extended?

When a school bus has its lights flashing and its stop sign extended, you must stop and remain stopped until the lights stop flashing or the stop sign folds back. This law is in place to protect children getting on or off the bus, as they may be crossing the street.

The flashing lights and extended stop sign indicate that children may be present and that drivers should take extra caution. By requiring drivers to stop completely during this situation, the law helps ensure the safety of pedestrians, particularly young ones, who might not yet be fully aware of traffic rules.

It's important to recognize that this applies to all vehicles regardless of the direction they are traveling — drivers approaching from either direction must adhere to this requirement. Ignoring this rule can lead to severe consequences, including fines and penalties, as well as posing a serious danger to children’s safety.
