A New York driver asks why a family-only non-commercial trip in a large van is treated differently from a for-hire passenger trip. What is the best answer?

1. NY CDL-10 excludes transportation of only family members for non-commercial purposes from the Passenger endorsement requirement
2. Family members never count as passengers for any traffic law
3. A for-hire passenger trip never requires a CDL if it stays intrastate
4. The Passenger endorsement applies only when every seat is occupied
