Answer: (B)

The amber warning lights on a school bus serve the critical function of alerting other drivers that the bus is preparing to make a stop. When these lights are activated, it signals to vehicles in the vicinity that the bus is about to engage its red lights and extend its stop arm, indicating that children may be getting on or off the bus shortly. This helps ensure the safety of students as they approach or depart from the bus, allowing other drivers ample time to slow down and prepare to stop.

This use of amber lights is part of a standardized procedure aimed at enhancing safety around school buses, particularly in areas where children frequently cross streets or wait at bus stops. Hence, the activation of these warning lights is a critical safety measure in the school transportation system, emphasizing the importance of vigilance from all road users when near school buses.
