Final answer:
A driver should stop and wait when approaching a stopped school bus with alternately flashing red lights to ensure the safety of children. The driver must remain stationary until the lights stop flashing and it is safe to proceed.
Step-by-step explanation:
When approaching the rear of a stopped school bus that has its alternately flashing red lights, a driver should stop and wait until the lights stop flashing. This is a standard traffic law designed to protect the safety of children as they enter or exit the school bus. Ignoring this law and failing to stop can lead to serious legal consequences, including fines and points on your driver's license. The correct action is to bring your vehicle to a complete stop, maintain a safe distance from the bus, and remain stationary until the red lights are no longer flashing, and it is safe to proceed.
