What should you do if you encounter a school bus with flashing red lights?

Answer: B — Stop and wait until the lights stop flashing

When encountering a school bus with flashing red lights, stopping and waiting until the lights stop flashing is crucial for several reasons. This action is necessary to ensure the safety of children who may be boarding or disembarking from the bus. The flashing red lights indicate that the bus is either picking up or dropping off students, and it is illegal to pass a stopped school bus in such situations, regardless of the direction you are coming from. This regulation is in place to protect children, as they are often in close proximity to the street and may not be aware of oncoming traffic. By stopping, you are providing a safe environment for students and complying with traffic laws designed to prevent accidents. Once the red lights stop flashing and the bus has resumed driving, it is then safe to proceed. This understanding is vital for all drivers to contribute to the safety of children in school zones.
