In a rig pulling two or more trailers, which trailer belongs in the spot right behind the tractor?

Correct answer: Whichever trailer is heaviest.

Answer options

  1. AWhichever trailer is lightest
  2. BWhichever trailer is shortest
  3. CWhichever trailer is heaviest Correct

Why

Hook the heaviest trailer up first, directly behind the tractor, and put the lightest one at the rear; a heavy trailer at the back makes the combination less stable and more likely to overturn.
