Much more care should be taken when driving trac-
tor-trailer than when driving tractor only.
Observe the following inspection and operation
methods.
(1) Turning of tractor-trailer
1. When turning your tractor-trailer, note the
trailer's running track and gradient.
2. On the turning track of the trailer, the trailer's
rear section enters the inside of the turning
direction in a large way. Watch out behind
you through the rear-view mirror while turn-
ing your tractor-trailer.
(2) Jack knife phenomenon
Jack knife phenomenon will occur if the trailer
would not comply with the movement of the trac-
tor when driving down a hill or turning the wheel
abruptly or applying quick braking.
(3)
Plow out
This is a phenomenon where the front wheel of
the tractor is locked and consequently the trac-
tor and the trailer stand at right angles to each
other.
(4)
Trailer swing
This is a phenomenon where the rear wheel of the
trailer is locked and consequently the trailer swings.
