STYLES OF BACKING (VIEW AND BLIND SIDE)
a. Straight line. This is used when there is ample space available in front of the dock (at least 100 feet).
b. Parallel parking. This is often used in truck stops and on the sides of private property.
c. Angular-Clean Canadian. When the space in front of the dock is around 100 feet and there is no need to jackknife the tractor trailer.
d. Angular-Dirty New York. This is used in exceptional tight spots. The name dirty implies some spinning of the trailer wheels. This has to be extremely carefully used when you are left with no choice.
e. Serpentine. This implies simultaneous use of view and blind side to park the tractor trailer in spots which need a special manoeuvre. The fender mirrors might have to be moved and the wheel base reduced to complete the parking.
f. Jackknife. This is used when there is so less a space in front of the dock that the tractor trailer cannot be straightened out and the loading/unloading has to be done in an L Shape.
