In what situation must you stop for a school bus with its stop signals displayed?

Answer: A — When all of the above are true

When a school bus has its stop signals displayed, it's essential to stop in various situations to ensure the safety of children boarding or disembarking from the bus. This requirement encompasses multiple scenarios, which is why selecting the option indicating that all statements are true is correct. Stopping for a school bus with its stop signals means that drivers must halt their vehicles regardless of their direction of travel. This includes situations on both one-way streets and at red lights, as well as when students are present. The law is designed to protect students who may be crossing the street or waiting to board the bus, making awareness of school bus stop signals critical for all drivers. In this context, observing a school bus's stop signals is a clear directive to ensure safety, reinforcing the principle that vehicle operation must account for the presence of children in the vicinity. Stopping in every relevant situation helps prevent accidents and reinforces responsible driving behavior.
