What should you do if you encounter a school bus with its stop sign extended?

When you encounter a school bus with its stop sign extended, the correct action is to immediately stop and wait. This is a critical safety measure designed to protect children who are getting on or off the bus. The stop sign being extended signals that children may be crossing the road, making it essential for all motorists to come to a complete stop until the bus's lights are no longer flashing and the stop sign is retracted.

This rule is in place to ensure the safety of young pedestrians, who may not always be aware of their surroundings. By stopping, you allow children the time and space they need to safely enter or exit the bus, significantly reducing the risk of accidents. Proper adherence to this traffic regulation is also crucial for following Massachusetts state laws regarding school bus safety.
