Massachusetts Driver's Instructor Practice Exam 2026 – Complete Prep Guide

When a school bus has its lights flashing and its stop sign extended, the law requires you to stop your vehicle until the warning lights stop flashing. This is a crucial safety measure designed to protect children who are getting on or off the bus. The extended stop sign indicates that it is unsafe to proceed as children may be crossing the street or close by, potentially putting them at risk of being struck by a vehicle.

Stopping ensures that drivers are aware of the potential hazards and allows children to cross safely. It's important to recognize that even if there are no children visibly crossing, the law mandates stopping because the lights are indicative of a safety zone around the bus. Therefore, understanding and adhering to this rule not only aligns with legal requirements but also shows a commitment to the safety of children and the community.
