What should a school bus driver do when approaching a school bus stop?

Answer: C — Slow down and be prepared to stop

When approaching a school bus stop, the appropriate action for a school bus driver is to slow down and be prepared to stop. This is crucial because school bus stops are typically established in areas where children may be boarding or disembarking from the bus. By slowing down, the driver can effectively react to any unexpected movements from children, who may quickly cross the street or come into the bus's path without warning. Moreover, this practice aligns with safety protocols designed to protect children. Most school bus laws stipulate that drivers must be vigilant and ready to halt their vehicle when nearing a stop where children are present. This precaution ensures that the driver can stop in time if children suddenly appear or if other factors necessitate an immediate halt. Maintaining speed, accelerating, or stopping abruptly are less safe alternatives in this context, as they do not account for the potential hazards present around school bus stops.
