An operator can easily detect this issue when performing the
required visual inspection of the tractor trailer coupling. The
operator will notice that the release handle is not fully retracted
in the closed/locked position with the lock notch behind the rib
as shown

and the hook is not engaged behind the
lock
(Figure 4)
. If the release handle is not in the closed/locked
position the fifth wheel is NOT locked.
IMPORTANT:
A fifth wheel may pass a tug test even if
the locking mechanism is NOT securely closed
around the kingpin.

wheel top plate above the fifth wheel bracket pin or on the
