If you turn with the tractor/triple trailer combination, which of the following is correct about the wheels that off-track (cheat) the most?

Longer vehicles will off-track more. The rear wheels of the powered unit (truck or tractor) will off-track some, and the rear wheels of the trailer will off-track even more. If there is more than one trailer, the rear wheels of the last trailer will off-track the most. [California Commercial Driver Handbook]
