. After more than 30 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter...a lot! Your vehicle has a light that comes on as a reminder to buckle up. See Safety Belt Reminder - 2005 Buick Century | Owner's Manual - Page 14
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. 1-8 - 2005 Buick Century | Owner's Manual - Page 15
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... 1-9 - 2005 Buick Century | Owner's Manual - Page 16
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. 1-10 - 2005 Buick Century | Owner's Manual - Page 17
Safety Belts Q: If I am a good driver, and I never drive far from home, why should I wear safety belts? A: You may of them in the future.

Q: What is wrong with this? {CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen.

Child Restraints Older Children Q: What is the proper way to wear safety belts? A: If possible, an older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck.
