Q:
A:
If I’m a good driver, and I never drive far from
home, why should
I wear safety belts?
You may be an excellent driver, but
if you’re in an
accident
- even one that isn’t your fault - you and
your passengers can be hurt. Being a good
driver doesn’t protect you from things beyond your
control, such as bad drivers.
Most accidents occur within
25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than
40 mph
(65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, see
Older Children on page 1-30
or lnfants and Young Children on page 1-32. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
Driver Position
This part describes the driver’s restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats’’ in the Index.
We’ll start with the driver position.
1-13

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, see
Driver Position on page 1-13.
The right front passenger’s safety belt works the same
way as the driver’s safety belt-except for one thing.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature
which may turn
off the passenger’s frontal air bag. If this
happens unintentionally, just let the belt go back all
the way and start again.
Center Passenger Position
1-22

Accident statistics show that children are safer if they
are restrained in the rear seat.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.
Child Restraints
Older Children
Q:
A:
Older children who have outgrown booster seats should
wear the vehicle’s safety belts. What
is the proper
way to wear safety belts?
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. The lap belt
should
fit snugly below the hips, just touching the
top of the thighs.
It should never be worn over
the abdomen, which could cause severe or even
fatal internal injuries in
a crash.
If you have the choice, a child should sit in a seat that
has a lap-shoulder belt to get the additional restraint
a shoulder belt can provide.

-
!ver do this.
Here two children are wearing the same belt.
The belt can’t properly spread the impact
forces.
In a crash, the two children can be
crushed together and seriously injured.
A belt
must be used by only one person at a time.
Q: What if a child is wearing a lap-shoulder belt,
but the child is
so small that the shoulder belt
is very close to the child’s face or neck?
be sure that the shoulder belt stili is on the child’s
shoulder,
so that in a crash the child’s upper
body would have the restraint the belts provide.
If the child is sitting in a rear seat outside position,
see
Rear Safety Belt Comfort Guides for Children
and Small Adults
on page 1-27.
If the child is so small that the shoulder belt is still
very close to the child’s face or neck, you might
want to place the child in a seat that has a lap belt,
if your vehicle has one.
A: Move the child toward the center of the vehicle, but

Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child.
If the child wears the belt in
CAUTION: (Continued) way,
in a cra-..
2 c .... d mig--- slide under
the belt. The belt’s force would then be applied
right on the child’s abdomen. That could cause
serious
or fatal injuries.
Wherever the child sits, the lap portion
of the belt
should be worn low and snug on the hips, just touching
the child’s thighs. This applies belt force to the child’s
pelvic bones in a crash.
Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone,
to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up
to some age
must be restrained while
in a vehicle.
Every time infants
and young children ride in vehicles,
theyshould have the protection provided by appropriate
restraints. Young children should not use the vehicle’s
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.
