Trailer Sway, Rollover & Rearward Amplification

Why are empty or lightly loaded trailers more prone to sway in strong crosswinds?

  • A.Empty trailers have no sway at all
  • B.Wind only affects loaded trailers
  • C.They are light and tall, so wind pushes them easily and their tires have less grip from weight
  • D.Light trailers are shorter
Correct answer

C. They are light and tall, so wind pushes them easily and their tires have less grip from weight

Why

A tall, light trailer presents a large sail area with little weight holding its tires to the road. Gusts can push it sideways or start a sway that a loaded trailer would resist.
