Stacked Loads
- Load paper rolls on a second layer only if the bottom layer extends to the front of the vehicle.
-
Prevent forward, rearward, or side-to-side movement:
- Either by the same means required for the bottom layer
- Or by the use of a blocking roll from a lower layer.
- A roll in the rearmost row of any layer must not be raised using dunnage.

A dunnage bag is:
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.

Dunnage bag:
An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
Which of the following can be used as part of the cargo securement system?
- Securing devices.
- Vehicle structure.
- All of these are valid.
- Blocking and bracing equipment.
What is a securement system?
A securement system is a securement method that uses one or a combination of the following elements:
- Vehicle Structure.

- Blocking and Bracing Equipment.
When securing building materials, how many tiedowns are required for top tier bundles longer than 5 ft?
- 2
- 0
- 1
- It depends on weight
Tiedowns over the top tier of bundles with a minimum of 2 tiedowns over each top bundle longer than 1.52 m (5 ft).
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.
Which of the following is not a reason why loads should be secured?
- Prevent loss of load
- Make it look pretty
- Avoid fines and citations
- Prevent damage to the cargo
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
When securing paper rolls with eyes crosswise, which of the following can be used to prevent side-to-side shifting when there is more than 8 inches of space to the wall?
- Friction mats.
- Void fillers.
- Tiedowns.
- Any of these methods are acceptable.
Requirements for eyes crosswise: prevent rolls from shifting toward either wall
If there is more than a total of 203 mm (8 in) of space between the ends of a paper roll and other rolls or the walls of the vehicle, use one of these methods:
- Void fillers (such as honeycomb)
- Blocking
- Bracing
- Friction mats
- Tiedowns
To satisfy general cargo securement requirements, what is the minimum WLL for securing vehicles under 10,000 lbs?
- 10,000 lbs.
- 30% of the weight of the cargo.
- 4,500 lbs.
- 50% of the weight of the cargo.
Note: More tiedowns may be required to satisfy the general cargo securement requirements. The Standard states: "The sum of the working load limits from all tiedowns must be at least 50% of the weight of the cargo."
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.
