Which trailer in a triple set deserves the closest watch in your mirrors and the gentlest steering inputs?
- A.The front trailer, because it is closest to the tractor
- B.All trailers behave identically, so none needs extra attention
- C.The last (rear) trailer, because swing and rollover tendency are greatest at the very back of the set
- D.The dolly between the first and second trailers
Correct answer
C. The last (rear) trailer, because swing and rollover tendency are greatest at the very back of the set
Why
Amplification builds unit by unit, so the tail of the set moves the most in every correction, curve, and gust. Drivers who watch the rear trailer catch trouble at its source.
