What is required of drivers when school children are entering or exiting a school bus?

Answer: B — Stop and remain stopped until children are safely across

When school children are entering or exiting a school bus, drivers are required to stop and remain stopped until the children have safely crossed the road. This law is in place to ensure the safety of children, who may not always be aware of the surrounding traffic and may suddenly move into the roadway. The requirement to stop protects the children as they embark or disembark from the bus, reducing the risk of accidents. This rule is crucial because when the bus has its stop sign extended and red lights activated, it indicates that children are potentially crossing in the vicinity, and all vehicles must cease movement. Drivers must be vigilant in these situations to safeguard young pedestrians, emphasizing the need to prioritize their safety above all other driving considerations.
