What is the minimum amount of rearward force that a cargo securement system must withstand?
- 80% of cargo weight
- 100% of cargo weight
- 50% of cargo weight
- 20% of cargo weight
Click here to look up the answer
From The CDL Manual
Each cargo securement system must be able to withstand a minimum amount of force in each direction.
- Forward Force = 80% of cargo weight when braking while driving straight ahead.
- Rearward Force = 50% of cargo weight when accelerating, shifting gears while climbing a hill, or braking in reverse.
- Sideways Force = 50% of cargo weight when turning, changing lanes, or braking while turning.
-
Upward Force = 20% of cargo weight when traveling over bumps in the road or cresting a hill.
- This requirement is satisfied when the cargo is "Fully Contained."
