What is the minimum weight of a load of metal coils that requires specific securement practices?
- 50,000 lbs
- 2,268 lbs
- It depends on the size of the coils.
- 5,000 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.
When securing concrete pipe loaded crosswise, arrange the top tier:
- Any of these are acceptable.

In what circumstance can shortwood be treated as longwood?
- When it is embedded in a stack of longwood.
- When it is stacked long-ways on the trailer.
- When it is painted green on the ends.
- Right after it is cut down.
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.
The Aggregate Working Load Limit should, at minimum, be:
- 80% of the weight of the cargo.
- 50% of the weight of the cargo.
- 100% of the weight of the cargo.
- Determined by the shipper.
How much should the Aggregate Working Load Limit be?
The aggregate working load limit of any securement system must be at least 50% of the weight of the cargo being secured.
Cargo is contained when:
- It is loaded on the end of the truck.
- 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 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.
In cargo securement, a wedge is defined as:
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
- A tapered piece of material, thick at one end and thin at the other, used to help keep cargo from moving.
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
Wedge:
A tapered piece of material, thick at one end and thin at the other, used to help keep cargo from moving.
The narrowest end of a boulder should be pointed:
- It doesn't matter.
- Towards the rear of the vehicle.
- Towards the front of the vehicle.
- Towards the sky.
If a boulder is tapered, point the narrowest end towards the front of the vehicle.
When securing metal coils with eyes vertical, the angle between tiedown and deck, if possible, should be:
- 60 degrees
- Less than 45 degrees
- Between 60 and 90 degrees
- 180 degrees
- Attach at least one tiedown against front of row of coils to restrain against forward motion. If possible, angle between tiedown and deck should be less than 45, when viewed from the side of the vehicle.
- Attach at least one tiedown against rear of row of coils to restrain against rearward motion. If possible, angle between tiedown and deck should be less than 45, when viewed from the side of the vehicle.
- Attach at least one tiedown over top of each coil or side-by-side row of coils to restrain against vertical motion. Tiedowns going over top of coil(s) must be as close as possible to eye of coil.
- Arrange tiedowns, blocking, or bracing to prevent shifting or tipping in all directions.
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.
