What must you always do when you see a school bus with its stop sign extended?

Answer: C — Stop your vehicle

When you see a school bus with its stop sign extended, it is crucial to stop your vehicle. This law is in place to protect children who are getting on or off the bus, as they may be crossing the street or walking in the vicinity of the bus. By stopping, you ensure that these young pedestrians can do so safely without the risk of being harmed by an oncoming vehicle. It is also important to note that in North Carolina, failure to stop for a school bus with its stop sign extended can result in serious legal penalties, including fines and points on your driving record. The law is designed to emphasize the importance of caution in areas where children are present, ensuring that drivers remain vigilant and responsible.
