9. Positioning Sliding
Fifth Wheels
NEVER reposition a sliding
fifth wheel while the

or on public roads. Failure
to avoid could cause loss of
vehicle control or tractor-
trailer separation which, if
not avoided, could result in
death or serious injury.
1. Position the tractor and trailer, in straight
alignment, on firm, level ground clear
of obstacles and persons.
2. Place the tractor into neutral and set the
tractor and trailer parking brakes.
