Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to be
seriously injured if they do not wear
safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap portion
should be worn as low as possible,
below the rounding, throughout
the pregnancy.The best way to protect the fetus is to
protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the safety belt will fasten around
you, you should use it.
But if a safety belt is not long
enough, your dealer/retailer will order
you an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be long
enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to t. The extender
has been designed for adults.
Never use it for securing child seats.
To wear it, attach it to the regular
safety belt. For more information, see
the instruction sheet that comes with
the extender.
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle’s safety belts.
