Trailer Sway, Rollover & Rearward Amplification

How should you handle a freeway off-ramp curve in a combination vehicle?

  • A.Slow to a safe speed before entering the curve, often well below the posted ramp speed, and hold a steady speed through it
  • B.Enter at the posted speed and brake in the middle
  • C.Accelerate slightly as the curve tightens
  • D.Coast in neutral through the ramp
Correct answer

A. Slow to a safe speed before entering the curve, often well below the posted ramp speed, and hold a steady speed through it

Why

Posted ramp speeds are set for cars, not top-heavy combinations. Braking mid-curve adds forward weight shift to side forces, so the speed must be right before you enter.
