Seat belts are most effective 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. All occupants of a car every time the car is driven. ✓

Answer: D. All occupants of a car every time the car is driven.

Seat belts are most effective when all occupants of a car wear them every time the car is driven.

Why this is the answer

The manual says seat belts save lives and can prevent serious injuries in crashes, and New York law requires adults in motor vehicles to use them. It states that the driver must be properly restrained and that a passenger age sixteen or older must also be properly restrained, one person per belt. It also warns that during a crash an unrestrained person becomes a flying object and a danger to everyone in the vehicle. That supports everyone in the car being belted on every trip, not just some people or some drives.

Why the other answers are wrong

Remember it

Think: every person, every belt, every trip.
