What is the Alberta school bus rule when its stop arm is extended and lights are flashing?

• A. Only traffic behind the bus must stop.
• B. All traffic must stop in both directions and remain stopped until the lights stop flashing and the arm retracts.
• C. Traffic may proceed if they are far away.
• D. Only traffic in the same direction must stop.

Answer: (B)

When a school bus extends its stop arm and flashing red lights, it signals that children may be boarding or crossing. The safest and correct response is to stop all traffic in both directions and remain stopped until the lights stop flashing and the stop arm retracts. This protects children from unexpected movements and gives them time to cross or board safely. You should not proceed or try to pass the bus during this signal. The obligation applies for the duration of loading and unloading and ends only when the arm retracts and the lights are off.
