yellowblueHere Are Questions Many People AskAbout Safety Belts -- and the AnswersQ: Won’t I be trapped in the vehicle after anaccident if I’m wearing a safety belt?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’s whysafety belts make such good sense.A:You could be -- whether you’re wearing a safetybelt or not. But you can unbuckle a safety belt,even if you’re upside down. And your chance ofbeing conscious during and after an accident, soyou can unbuckle and get out, is much greater ifyou are belted.Q:If my vehicle has air bags, why should I have towear safety belts?A:Air bags are in many vehicles today and will be inmost of them in the future. But they aresupplemental systems only; so they work withsafety belts -- not instead of them. Every air bagsystem ever offered for sale has required the use ofsafety belts. Even if you’re in a vehicle that has airbags, you still have to buckle up to get the mostprotection. That’s true not only in frontal collisions,but especially in side and other collisions.1-11

yellowblueQ:If I’m a good driver, and I never drive far fromhome, why should I wear safety belts?A:You may be an excellent driver, but if you’re in anaccident -- even one that isn’t your fault -- you andyour passengers can be hurt.
