When may hazard lights or 4-way flashers not be used on a school bus?

• A. When driving on highways
• B. Approaching or at a school bus stop
• C. When parked in a school lot
• D. During rainy conditions

Answer: (B)

Hazard lights or 4-way flashers on a school bus are specifically intended for warning other drivers of a potential hazard or when the bus is stopped unexpectedly. When a school bus is approaching or at a school bus stop, using hazard lights can cause confusion for other drivers. It may lead them to believe they should slow down or stop, which is unnecessary when the bus is already following proper protocol for stopping. Instead, the bus should rely on its stop sign and flashing red lights to indicate to other vehicles that they must halt their progress to ensure the safety of children boarding or disembarking from the bus. This focused use of signals ensures clarity and reduces the risk of accidents in the vicinity of school bus stops.
