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.
Lap Belt
This part is only for the lap belt. To learn how to wear a
lap-shoulder belt, seeLap-Shoulder Belt on page 1-25.
You vehicle may have a center seating position.
When you sit in the center front seating position, you
have a lap safety belt, which has no retractor.
To make the belt longer, tilt the latch plate and pull it
along the belt.
Buckle, position and release it the same way as the lap
part of a lap-shoulder belt.
