This figure lights up when you turn the
key to Run or Start when your safety
belt isn’t buckled,
and you’ll hear a
chime,
too. It’s the reminder to buckle
up.
In many states and Canadian provinces,
the law says
to wearsafety belts. Here’s
why: They work.
You never lnow- if you’ll be in a crash.
If you do have a crash, you don’t know
if it will be a bad one.
A few crashes are very mild. In them,
you won’t get hurt even if you’re not
buckled up. And some crashes m be
so serious, 1ike.being-hit by a train, 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 someti-mes
walk
away. Without belts they could be
badly hurt or killed.
After 25 years of safety :belts in vehicles,
the facts are clear.
In most crashes
buckling up does matter ... a lot!
