CAUTION
A
sitting in a reclined position when your vehicle is in motion can be
1
I
,,.Igerous. Even i f 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 i t s 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
I
belt properly.
