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 don't wear
safety belts.
A pregnant woman should wear a lap-shoulder belt, and the lap portion
should be worn as low as possible throughout the pregnancy.
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
The right front passenger's safety belt works the same way as the driver's
safety belt. See "Driver Position," earlier in this section.
When the shoulder belt is pulled out all the way, it will lock. If it does, let it
go back all the way and start again.
Rear Seat Passengers
It's very important for rear seat passengers to buckle up! Accident statistics
show that unbelted people in the rear seat are hurt more often in crashes
than those who are wearing safety belts.
Rear passengers who aren't safety belted can be thrown out of the vehicle in
a crash. And they can strike others in the vehicle who are wearing safety
belts.
