Home › CDL Practice Tests › Combination Vehicles Questions › Question 77
How does liquid or hanging load movement relate to combination stability, in general principle?
- A.Shifting loads improve stability
- B.Loads that shift or surge move the center of gravity while driving and can add to sway and rollover forces
- C.Only dry freight can shift
- D.Load movement stops once you are moving
Correct answer
B. Loads that shift or surge move the center of gravity while driving and can add to sway and rollover forces
Why
Any load that moves changes where the weight acts, sometimes at the worst moment in a curve or lane change. Securing freight and driving gently limit both the shift and its effects.
