Seat belts can be most effective as injury preventive devices when they are worn by:

  1. The person driving the car
  2. Passengers when they are on a long drive
  3. All occupants of a car being driven on an expressway
  4. Passengers and the driver whenever they are in the car ✓

Answer: D. Passengers and the driver whenever they are in the car

Seat belts are most effective when the driver and all passengers wear them whenever they are in the car.

Why this is the answer

The New York manual says the driver must make sure every person in the vehicle is properly restrained, and the learner permit section says you and each passenger must wear a seat belt, one per person. It does not limit the requirement to the driver alone, to long trips, or to expressways. That makes the broad choice — passengers and the driver whenever they are in the car — the one the handbook supports.

Why the other answers are wrong

Remember it

Count people and belts before you move: every occupant needs a belt, every trip.
