Weight, Space & Doubles/Triples Handling

How does a high center of gravity in the rear trailer of a set affect safety?

  • A.A high load in the rear trailer steadies the whole set
  • B.Center of gravity only matters in the front trailer
  • C.High loads roll less because the weight presses the tires down
  • D.It raises that trailer's rollover risk, and the rear trailer is already the most likely to roll because of crack-the-whip amplification
Correct answer

D. It raises that trailer's rollover risk, and the rear trailer is already the most likely to roll because of crack-the-whip amplification

Why

The trailer with the most swing is the worst place for top-heavy cargo. Loading heavy items low, and respecting the rear unit's limits, addresses the set's weakest point.
