But don’t have a seatback reclined if your vehicle

Sittingin a reclined position whenyour vehicle is
in motion can be dangerous.Even if you buckle
up, your safety beltscan’t do their job when
you’re reclined like this.
The shoulder belt can’t
do itsjob because it
won’t beagainstyour body. Instead, it will be in
front of you. In
a crash you could go into it,
receiving neckorother injuries.
The lapbelt can’t do itsjob either. In a crash the
belt could
go up overyour abdomen. Thebelt
forces would be there,not atyour pelvic bones.
Thiscould causeseriousinternalinjuries.
For proper protectionwhen the vehicle
is in
motion, havethe seatback upright. Then sit
well back in the seat and wear your safety
belt properly.
