What should you do if you encounter a school bus with its stop sign extended?

When you see a school bus with its stop sign extended, the law requires you to stop your vehicle until the stop sign is retracted. This is crucial for the safety of children who may be getting on or off the bus. The extended stop sign indicates that children are present, and they may cross the road without warning. Stopping ensures that you are doing your part to protect them and allows for a safe environment for students.

Understanding the importance of this rule helps reinforce safe driving habits around school zones and demonstrates respect for the legal regulations designed to safeguard children. The other options suggest actions that could endanger children, such as passing the bus or merely slowing down without completely stopping, which would not comply with the law and could lead to serious consequences.
