At a stop, traffic behind the bus is still rolling forward even though the red warning lights are about to be activated. What is the safest door and student-signal decision?

1. Open the door so the red lights activate sooner
2. Make a final traffic check and do not open the door or signal students until traffic has stopped and it is safe
3. Signal students to run because traffic is slowing
4. Cancel the stop and unload at the next intersection without checking
