Final answer:
You must stop for a school bus with flashing red lights until the lights are turned off or you're signaled to proceed, to ensure the safety of children.
Step-by-step explanation:
If you are approaching a school bus from either direction and the bus has flashing red lights, you must stop until the bus has turned off its flashing red lights and has resumed motion or until signaled by the bus driver or a police officer that you can proceed. This rule ensures that children can safely enter and exit the bus. In an emergency situation, such as having a pregnant woman in your vehicle who is about to give birth, some may think breaking traffic regulations, like stopping for a school bus with flashing red lights, would be permissible if it led to greater overall good or utility. However, traffic laws are in place for the protection of all road users, and any exceptions should ideally be addressed with law enforcement or emergency medical services.
