A driver is unloading students who must cross the road. One student drops a lunchbox near the front bumper after reaching the roadway edge. What should the driver do?

1. Keep the bus secured, stop the crossing movement, account for the student, and retrieve or direct retrieval only when the child is in a safe place and visible
2. Signal the student to run back quickly before traffic moves
3. Close the door and move forward slowly so the student can see the lunchbox
4. Ask another student to crawl under the bus and get it
