When must you stop for a school bus?

The requirement to stop for a school bus is specifically indicated by the activation of its red lights and the extension of the stop arm. This situation indicates that children may be entering or exiting the bus, making it crucial for vehicles in both directions to stop to ensure their safety.

When the red lights are flashing and the stop arm extends, it serves as a clear signal that all traffic in both directions must come to a complete stop until the lights cease flashing and the stop arm retracts. This law is in place to protect children as they navigate around school buses.

While yellow lights and being in a school zone are important factors in the overall context of school safety, they do not warrant the same immediate requirement for all vehicles to stop as red lights and an extended stop arm do. The safety of children is paramount, which is why this specific signal necessitates a complete halt.
