What is the correct response if you see a school bus with its stop sign extended?

When you see a school bus with its stop sign extended, the correct response is to stop your vehicle and wait until the sign is retracted and the bus moves. This action is crucial for the safety of children entering or exiting the bus. The stop sign indicates that children may be crossing the street, and it is the law in many states, including Tennessee, to halt your vehicle when this sign is displayed. This measure protects students from being injured while they are in the vicinity of the bus, as they may be focused on getting to or from school and may not be looking out for vehicles. Thus, stopping ensures that you provide a safe environment for them.

The other options suggest actions that could endanger children. Slowing down and proceeding with caution does not ensure their safety, as it still allows for potential accidents. Honking the horn may cause confusion or panic among children, and overtaking the bus quickly disregards safety protocols entirely, putting students at significant risk. Stopping your vehicle is the most responsible and legally required response in this situation.
