Choose A Section:
Go!Cargo is contained when:
- It fills a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
- It is loaded on the end of the truck.
- it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
- It is packed in a square box.
Contained:
Cargo is contained if it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
The narrowest end of a boulder should be pointed:
- Towards the sky.
- Towards the front of the vehicle.
- It doesn't matter.
- Towards the rear of the vehicle.
If a boulder is tapered, point the narrowest end towards the front of the vehicle.
Which of the following is not true of Working Load Limit (WLL)?
- The minimum WLL requirement for the securement system is 25%.
- The WLL is usually assigned by the component manufacturer.
- All of these are true.
- The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system.
The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system during normal service.
The WLL is usually assigned by the component manufacturer.
Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.
When securing paper rolls with friction mats as a primary method:
- The friction mat should stick out from underneath the roll in the direction it is providing securement.
- The friction mat should stick out from underneath the roll in the opposite direction for which it is providing securement.
- Make sure friction mats are completely covered by the roll.
- All of these answers.
Requirements for friction mats
If a friction mat is used to provide the principal securement for a paper roll, insert the friction mat so that it sticks out from beneath the footprint of the roll in the direction in which it is providing securement.
When loaded cement pipe over 45 inches in diameter, which pipes should be blocked, wedged, or otherwise immobilized?

- When total weight is less than 5,000 lbs.
Special Circumstances: Loading and Securing Paper Rolls on a Flatbed Vehicle or a Curtain-Sided Vehicle
Requirements for eyes vertical or with eyes horizontal and lengthwise
Load and secure the paper rolls as described for a sided vehicle.
Attach tiedowns to secure entire load according to the general cargo securement requirements in Section 2.
Note: Stacked loads of paper rolls with eyes vertical are prohibited
What is the minimum weight of a load of metal coils that requires specific securement practices?
- 5,000 lbs
- It depends on the size of the coils.
- 2,268 lbs
- 50,000 lbs
Size of coil
All metal coil shipments that, individually or together, weigh 2,268 kg (5,000 lb.) or more must be secured according to the specific requirements in this section.
Exception: Metal coils that weigh less than 2,268 kg (5,000 lb.) may be secured according to general securement requirements.
One option of positioning bundles of building materials is:
- Place them in direct contact with each other.
- Lean them to the outside.
- Lean them against each other.
- Turn them so only their corners are touching.
Choose one of two options for positioning bundles:
-
Option #1:
Place bundles in direct contact with each other.
-
Option #2:
Provide a means (such as dunnage or blocking) to prevent the bundles from shifting towards each other.
When loading paper rolls with eyes horizontal, which of the following is not a requirement for stacking a second layer:
- Place second layer with eyes vertical.
- All the wells in the layer beneath must be filled
- The bottom layer must extend all the way to the front.
- It must be blocked against an eye-vertical blocking roll resting on the floor of the vehicle that is at least 1.5 times taller than the diameter of the roll being blocked.
Requirements for eyes crosswise: secure stacks of paper rolls from front-to-back movement
- Do not load paper rolls on a second layer unless the bottom layer extends to the front of the vehicle.
- Load paper rolls on higher layers only if all wells in the layer beneath are filled.
-
Secure the foremost roll in each upper layer (or any roll with an empty well in front of it) against forward movement:
- Either by placing it in a well formed by two rolls on the lower row whose diameter is equal to or greater than that of the roll on the upper row.
- Or by banding it to other rolls.
- Or by blocking it against an eye-vertical blocking roll resting on the floor of the vehicle that is at least 1.5 times taller than the diameter of the roll being blocked.
Which of the following is not a requirement for shortwood loaded lengthwise?
- Each outside log bearing against stakes should extend at least 6 in beyond the stakes at each end.
- Heavier logs must be stacked on top.
- Logs should be centered in the bunk.
- Must be cradled in a bunk or contained by stakes.
Requirements for shortwood loaded lengthwise
- Shortwood must be cradled in a bunk or contained by stakes.
- Logs should be centered in the bunk.
- Each outside log bearing against stakes should extend at least 0.15 m (6 in) beyond the stakes at each end.
About The Flatbed Cargo Securement CDL Manual
Studying the flatbed cargo securement CDL manual is not a requirement for getting your CDL permit or license. It is required knowledge for flatbed drivers.
Some questions you should be able to answer for flatbed cargo securement:
- What is the minimum Working Load Limit of a tiedown used to secure logs?
- What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
- When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
- What is a cab shield?
- When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
- What is a dunnage bag?
- Who is responsible for inspecting securing devices and cargo within the first 50 miles?
- How many tiedowns are required on a stack of shortwood loaded crosswise?
- What is the minimum working load limit of each tiedown used to secure crushed or flattened vehicles?
- Define 'bolster'
- What is a hook-lift container?
- When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
What is a securing device?
Any device specifically manufactured to attach or secure cargo to a vehicle or trailer:
- Synthetic Webbing
- Chain
- Wire rope
- Manila rope
- Synthetic rope
- Steel strapping
- Clamps and latches
- Blocking
- Front-end structure
- Grab hooks
- Binders
- Shackles
- Winches
- Stake pockets
- D-rings
- Webbing ratchet
- Bracing
- Friction mat
What is a tiedown?
A combination of securing devices that forms an assembly that:
- Attaches cargo to, or restrains cargo on a vehicle.
- Is attached to anchor point(s).
Some tiedowns are attached to the cargo and provide direct resistance to restrain the cargo from movement.
Some tie-downs pass over or through the cargo. They create a downward force that increases the effect of friction between the cargo and the deck. This friction restrains the cargo.
Related Cargo Securement Terms That Every Driver Should Know:
-
Tiedown:
A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
-
Contained:
Cargo is contained if it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
-
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
How should tiedowns be attached?
Tiedowns can be used in two ways:
-
Attached to the cargo:
- Tiedowns attached to the vehicle and attached to the cargo.
- Tiedowns attached to the vehicle, pass through or aroundan article of cargo, and then are attached to the vehicle again.
-
Pass over the cargo:
- Tiedowns attached to the vehicle, passed over the cargo, and then attached to the vehicle again.
Tiedown placement:
Place the tiedown as close as possible to the spacer.
Position the tiedowns as symetrically as possible over the length of the article.
Position the tiedowns to preserve the integrity of the article.
