When two trailers of different lengths are combined in a doubles setup, which one is normally placed first behind the tractor?
Pick an answer
Correct!
Not quite. The correct answer is highlighted.
Correct answer to question 47 (Doubles/Triples): The longer trailer is generally placed first, directly behind the tractor, with the shorter one behind it
Why
Placing the longer trailer first keeps the shorter, lighter trailer at the rear, which is the more stable arrangement rather than putting a longer unit out where sway is amplified most.
