Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Put someone on it. Take the simplest vehicle. Suppose it is just a seat on wheels. 1-11 - 2008 Pontiac Grand Prix | Owner's Manual - Page 16
Get it up to speed. Then stop the vehicle. The rider does not stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield... 1-12 - 2008 Pontiac Grand Prix | Owner's Manual - Page 17
or the instrument panel... or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That is why safety belts make such good sense. 1-13 - 2008 Pontiac Grand Prix | Owner's Manual - Page 18
If my vehicle has airbags, why should I have to wear safety belts? A: Airbags are supplemental systems only; so they work with safety belts - not instead of them. Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection. That is true not only in frontal - 2008 Pontiac Grand Prix | Owner's Manual - Page 19

Child Restraint Systems {CAUTION: The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed.

Even though today's airbags are also designed to help reduce the risk of injury from the force of an inflating bag, all airbags must inflate very quickly to do their job.
