But don’t have a seatback reclined if your vehicle is moving.
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts can’t do their job when
you’re reclined like this.
The shoulder belt can’t do its job because it
won’t be against your body. Instead, it will
be in
front of you. In
a crash you could go into it,
receiving neck or other injuries.
The lap belt can’t do its job either. In a crash the
belt could
go up over your abdomen. The belt
forces would be there, not
at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is
in
motion, have the seatback upright. Then sit well
back
in the seat and wear your safety belt properly.
