CDL · Combination vehicles

Which two actions do the most to keep a combination vehicle from rolling over?

Correct answer: Taking turns slowly and loading the cargo so it rides as low as possible.

Answer options

  1. ASpeeding up a little through curves and placing the heaviest cargo on top
  2. BHolding a low speed on open highways and keeping the load centered side to side
  3. CTaking turns slowly and loading the cargo so it rides as low as possible Correct

Why

A combination vehicle tips over most easily when its center of gravity is high and it takes a turn too fast. Loading cargo as low as possible and slowing down for turns address both causes, so they are the two most important precautions.
