How does a New York driving instructor properly prepare a student for the road test backing maneuver?

1. Tell the student only that they must back straight, without observation or control practice
2. Practice backing in a straight line for approximately 50-75 feet while maintaining control, staying in the lane, and checking mirrors and blind spots
3. Tell the student backing is not evaluated on the New York road test at all
4. Have the student use the backup camera exclusively instead of looking and checking mirrors
