The purpose of the flashing red lights on a school bus is to alert drivers to stop while children are getting on or off. This safety feature is essential because it provides a clear visual signal to other motorists that they need to halt their vehicles, ensuring the safety of children as they enter or exit the bus.

When the red lights are activated, it indicates that the bus is either loading or unloading students, who may be in close proximity to the road. Drivers are legally required to stop when they see these flashing lights, as children could be unexpectedly crossing the street or walking near the bus. This measure significantly reduces the risk of accidents and promotes a safe environment for children during their school commutes.

Other choices related to signaling movement, indicating fuel levels, or warning of breakdowns do not pertain to the primary function of the flashing red lights, as their sole purpose is to enhance the safety of students boarding or deboarding the bus.
