.If you care in a.crash and . .’

your iajuries can ,ibe..much worse.
You
can hit things,inside the

or be ejected from it. You
can be seriously injured or killed. In

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!

Safety Belt Extender
If the vehicle’s safety belt. will faslen
around you, you should use it; But if a
s&ty belt isjn’t long enough to fasten,
your deaier
will order you an extender.
It’s free. When
you go in to order-it,
take the heaviest coat you will wear, so-
the extender will be long enough for-
you, The -extender will be just for you,
and just for the seat in your vehicle that
you choo.se. Don? let someone else use-
it, and use it only for the seat it is made,
to fit. To wear it, just-attach it to the
regular safety belt.
Checking Your Restraint Systems
Now and then, make sure all your belts,
buckles, latch plates, retractors,
anchorages
.and reminder systems .are
working propedy. Look for any loose
parts or damage. If you see anything
that
might. keep a restraint system from
doing its job, have it repaired.
