A driver is loading students and sees one student disappear from the mirror view near the bus after dropping a book. What is the safest NY CDL-10 response?

1. Secure the bus and account for the student, checking around and underneath before moving
2. Move forward slowly so the student has room to retrieve the book
3. Signal the student to crawl under the front bumper
4. Ask traffic to pass on the left while the student retrieves the item
