What must you always do when you see a school bus with its red lights flashing?

When you see a school bus with its red lights flashing, it is essential to stop your vehicle because this is a clear indication that children are either boarding or disembarking from the bus. The red lights serve as a safety measure to alert drivers to the presence of students who may be crossing the road or near the bus. Stopping not only protects the children but is also a legal requirement in Pennsylvania and many other states. Failing to stop when the bus is displaying its red lights can result in significant penalties, including fines and points on your driving record.

It's important to remember that the law requires stopping regardless of the direction you are coming from when the bus is unloaded or loading passengers. This regulation is in place to ensure the safety of children, who may be unpredictable as they navigate in and around the bus.
