When is a school bus driver required to use their hazard lights?

Answer: B — When the bus is stopped and loading or unloading

A school bus driver is required to use their hazard lights specifically when the bus is stopped and engaged in loading or unloading passengers. This is crucial for safety, as it alerts other drivers and pedestrians that the bus is stationary and that children may be entering or exiting the vehicle. The use of hazard lights in this situation is a standard protocol intended to enhance visibility and protect the safety of the children getting on or off the bus. Using hazard lights draws attention to the stopped bus, making it clear to other road users that they should approach with caution and be prepared to stop if necessary. It creates a visual signal that emphasizes the importance of protecting young passengers during these potentially hazardous moments. In contrast, operating the bus with hazard lights on while moving, only during inclement weather, or at all times would not align with the regulations and guidelines set forth for school bus operation. These practices could lead to confusion for other drivers and undermine the specific purpose of activating hazard lights, which is predominantly associated with stopped conditions and the loading/unloading of passengers.
