What is a securement system?
A securement system is a securement method that uses one or a combination of the following elements:

- Securing Devices.
- Blocking and Bracing Equipment.
The definition for "shortwood" identifies pieces that are no longer than:
- 75 in
- 16 ft
- Half the length of the trailer.
- The width of the road.
Shortwood
- Normally up to about 2.5 m (100 in) in length.
- No longer than 4.9 m (16 ft) in length.
-
Also called:
- Cut-up logs

A container chassis vehicle is defined as:
- A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.
- A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
- A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.
- A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.
Container Chassis Vehicle:
A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
What is the minimum WLL required of tiedowns securing loaded intermodal containers on non-chassis vehicles?
- 80% of the loaded weight of the container.
- It depends on the length of the container.
- 50% of the loaded weight of the container.
- 20% of the loaded weight of the container.
Secure each container to the vehicle by:
- Either chains, wire ropes, or integral devices that are fixed to all lower corners.
- Or crossed chains that are fixed to all upper corners.
- Or both.
Secure the front and rear of the loaded container independently.
Secure the four corners using tiedowns that are attached to the loaded container.
The tiedowns must have an aggregate working load limit of at least 50% of the loaded weight of the loaded container.
Attach each chain, wire rope, or integral locking device to the container in a manner that prevents it from becoming unfastened while in transit.
Which of the following is not true of Working Load Limit (WLL)?
- 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.
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 metal coils in a sided vehicle without anchor points:
- Use locking and bracing
- All of these apply
- Use friction mats
- Follow general cargo securement requirements
Securing Coils Transported in a Sided Vehicle or Intermodal Container without Anchor Points
To prevent metal coils from moving horizontally and/or tipping:
Follow general cargo securement requirements
Secure the coils using:
- Blocking and bracing
- Friction mats
- A combination of these.
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 alternate on opposite sides of the vehicle.
- If possible, the ends of consecutive pipe must be staggered within the allowable width.
- Load bell pipe on one tier so that the bells all lie on one side of the vehicle.
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.
Which of the following is not a requirement of wood used as blocking or bracing?
- It should be free of decay and structural defects.
- It should be painted.
- Hardwood is recommended.
- It should be properly seasoned.
If wood is used:
- Hardwood is recommended.
- It should be properly seasoned.
- It should be free from rot or decay, knots, knotholes, and splits.
What is bell pipe concrete?
- Pipe whose flanged end is of larger diameter than its barrel.
- Concrete used to make bell pipe.
- Pipe used to make concrete bells.
- Pipe whose flanged end is of smaller diameter than its barrel.
Bell Pipe Concrete:
Pipe whose flanged end is of larger diameter than its barrel.
What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
- 10,000 lbs
- 5,000 lbs
- 2,268 lbs
- It depends on how they're loaded
The rules in this section apply to shipments of paper rolls, which individually or together, weigh 2268 kg (5000 lb.) or more.
Note: Shipments of paper rolls that weigh less than 2268 kg (5000 lb.), and paper rolls that are unitized on a pallet may either be secured in accordance this section or with the general cargo securement requirements
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

- 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.
