Right Front Passenger Position
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.
The right front passenger's safety belt works the same
way as the driver's safety belt. See "Driver Position,''
earlier in this part.
When the lap portion of the belt is pulled out all the
way, it will lock. If it does, let it go back all the way and
start again.
If your vehicle has a center passenger position, be sure
to use the correct buckle when buckling your
lap-shoulder belt. If you find that the latch plate will not
go fully into the buckle, see if you are using the buckle
for the center passenger position.
