Seat belts are most effective when they are worn by:
The person driving the car.
Passengers when they are on a long drive.
All occupants of a car being driven on an expressway.
All occupants of a car every time the car is driven.
When you drive, make sure each person in your vehicle wears a seat belt. In the event of a crash, a person without a seat belt becomes a flying object and a danger to each person in the vehicle.
