What should you do when seeing a school bus with flashing red lights?

Answer: B — Stop no closer than 20 feet from the bus

When you see a school bus with flashing red lights, stopping no closer than 20 feet from the bus is the correct response because it ensures the safety of children who may be boarding or disembarking from the bus. The flashing red lights are a clear indication that the bus is either picking up or dropping off children, and state laws require drivers to stop to protect these vulnerable individuals. By maintaining a safe distance of at least 20 feet, you not only comply with the law but also provide ample space for children to cross the road safely if necessary. Remaining at a safe distance prevents any potential accidents and shows awareness of the heightened risk in these situations where children are present. This action is critical for ensuring their safety, as children may not always be visible to drivers or may unexpectedly step out into the roadway.
