Go!In what circumstance can shortwood be treated as longwood?
- When it is painted green on the ends.
- When it is embedded in a stack of longwood.
- Right after it is cut down.
- When it is stacked long-ways on the trailer.
What's in a stack?
Some stacks may be made up of both shortwood and longwood. Any stack that includes shortwood must follow the shortwood securement requirements.
Exception: If shortwood is embedded in load of longwood, it can be treated as longwood.
Cargo is contained when:
- It is packed in a square box.
- 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 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.
Contained:

In case of low friction between the cargo and deck, which of these is not a solution?
- Use some kind of blocking.
- Attach tiedowns to the cargo.
- Set the cargo on friction mats.
- Put something heavy on top of the cargo.
What should you use in low-friction situations?
When there is low friction between the cargo and the deck (for example, with snow, ice, sand, gravel, and oil):
- Use tiedowns attached to the cargo.
- Use a means to improve the friction such as friction mats or tiedown that pass over the cargo.
- Use blocking and tiedowns.
When loading bell pipe on one tier, all of the following apply except:
- If the ends cannot be staggered, they must be aligned.
- Load bell pipe on one tier so that the bells all lie on one side of the vehicle.
- Load bell pipe on one tier so that the bells alternate on opposite sides of the vehicle.
- If possible, the ends of consecutive pipe must be staggered within the allowable width.
One tier
Load bell pipe on one tier so that the bells alternate on opposite sides of the vehicle.
If possible, the ends of consecutive pipe must be staggered within the allowable width.
If the ends cannot be staggered, they must be aligned.
If you were instructed to 'tarp' a load, what would you be using?
- A platform or tray on which cargo is placed so that it can be handled as an article.
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself.
- A waterproof sheet used to cover cargo.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
Tarp:
A waterproof sheet used to cover cargo.
Banding is:
- A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
- 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).
- Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.

Which of the following is not a reason why loads should be secured?
- Make it look pretty
- Prevent loss of load
- Prevent damage to the cargo
- Avoid fines and citations
Why secure your load? To prevent:
- Loss of life
- Loss of load
- Damage to the cargo
- Damage to the vehicle
- Issuance of citations/fines to driver/carrier
- The vehicle being placed Out-of-Service.
- A crash
What is the maximum angle recommended for tiedowns securing cement pipe loaded crosswise, relative to the deck?
- It doesn't matter
- 45 degrees
- 45-90 degrees
- 180 degrees
If the first pipe of a group in the top tier is not at the front of the tier beneath:
Attach an additional tiedown that runs rearward at an angle not more than 45 to the horizontal when viewed from the side of the vehicle, whenever practical.
Pass tiedown either through the front pipe of the upper tier or outside the front pipe and over both longitudinal tiedowns.
When securing concrete pipe up to 45 inches loaded crosswise, tiedowns through the pipe must be:
- Chains
- Wire.
- Straps.
- Nylon rope.
Tiedown requirements
- Pipe may be secured individually or as a group.
- Tiedowns through the pipe must be chains.
- Front-to-back tiedowns may be chain or wire rope.
Which of the following is not true of Working Load Limit (WLL)?
- The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system.
- All of these are true.
- The minimum WLL requirement for the securement system is 25%.
- The WLL is usually assigned by the component manufacturer.
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.
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.
