Medium Duty Operator's Manual - Peterbilt Motors Company

SEATS
• Be sure, also, that your belt is not too loose. A loose
belt could allow you to slide under it in an accident,
and that could bring the belt up around your abdomen.
• Do not twist the belt in the process of putting it on. A
twisted belt will not work as well to protect you.
WARNING! Always wear your seat belt low
over your pelvic bones.
• You can be seriously injured if your belt is
buckled too high. In a crash, it would apply
force to your abdomen, not your pelvic
bones. This can result in serious internal
injuries.
• Do not drive with your seat belt loose. A
seat belt that is too loose can allow you to
fall too far forward, possibly causing head
and neck injuries. You could strike the
wheel or the windshield. Adjust your belt so
that there is no more than 1 in. (25mm) of
slack.
WARNING! Do not wear the shoulder belt
under your arm or otherwise out of position.
In a crash your body would move too far forward,
increasing the chance of head and neck
injury. Also, the belt would apply too much
force to the ribs, which are not as strong as
your shoulder bones, and could cause you to
suffer internal injuries. Wear the shoulder belt
over your shoulder (see “Safety Restraint Belts”
on page 73).
WARNING! Do not twist the belt in the process
of putting it on. A twisted belt will not work as
well to protect you. In a crash, the full width of
the belt would not be protecting you. A
twisted belt could cut into your body and
cause serious injuries. Straighten the belt
before buckling it. If you are unable to wear it
without twisting it, have your dealer or service
person repair it as soon as possible.
