If adult seat belts do not fit properly, use a booster seat. Also, children must never ride on the laps of others. It is available from Transport Canada or the Canadian Automobile Association. Their addresses and phone numbers can be found on the contact page of this site. Passengers must always wear seat belts.
Seat belts reduce the distance that they can move forward during a crash.
Move the seat toward the rear. Even with the passenger seat all the way forward, the distance between a passenger's chest and the dashboard, where the air bag is stored, is usually more than 25 cm. But more distance is safer. Since the risk zone for air bags is the first 8 cm of inflation, placing yourself 25 cm from your driver air bag provides you with a clear margin of safety. This distance is measured from the center of the steering wheel to the center of your sternum.
