Why Safety Belts Work - Cadillac 2005 XLR Owner's Manual

You never know if you'll be in a crash. If you do have a
crash, you don't know if it will be a bad one.

serious that even buckled up a person wouldn't survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes walk
away. Without belts they could have been badly hurt
or killed.
After more than 30 years of safety belts in vehicles, the
facts are clear. In most crashes buckling up does
matter...a lot!
