When loading paper rolls with eyes horizontal, which of the following is not a requirement for stacking a second layer:
- The bottom layer must extend all the way to the front.
- All the wells in the layer beneath must be filled
- Place second layer with eyes vertical.
- 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.
When securing a paper roll with a width that is more than twice its diameter, which of the following is not an acceptable method of securement to prevent tipping?
- Use tiedowns.
- Brace it.
- Use rear doors to brace it.
- Band the roll to other rolls.
Situation #1:
- Paper roll is not prevented from tipping by the vehicle structure or other cargo.
- Paper roll width is more than 2 times its diameter.
Solution #1:
- Either band the roll to other rolls.
- Or brace it.
- Or use tiedowns.
When securing building materials, how many tiedowns are required for top tier bundles longer than 5 ft?
- 0

- 1
Tiedowns over the top tier of bundles with a minimum of 2 tiedowns over each top bundle longer than 1.52 m (5 ft).
As part of their pre-trip cargo securement inspection, drivers should:
- Check for anything that will obscure their vision.
- Make sure cargo is properly secured.
- All of these apply.
- Inform carrier of any inadequate packaging.
Driver inspection checklist:
Pre-Trip
- Make sure that cargo is properly distributed and adequately secured (in other words, according to the Standard).
- Make sure that all securement equipment and vehicle structures are in good working order and used consistent with their capability.
- Stow vehicle equipment.
- Make sure that nothing obscures front and side views or interferes with the ability to drive the vehicle or respond in an emergency.
-
Inform carrier if packaging is not adequate. For example:
- Banding is loose or not symmetrical on package.
- Banding attachment device(s) are inefficient.
- Wrapping is broken or ineffective.
- Pallets are broken.
When securing concrete pipe loaded crosswise, arrange the top tier:
- As a complete tier.
- As a partial tier in two groups.
- As a partial tier in one group.
- Any of these are acceptable.
Requirements for arranging the top tier
Arrange the top tier as a complete tier, a partial tier in one group, or a partial tier in two groups.
How many tiedowns are required on a stack of shortwood loaded crosswise?
- 3
- It depends on the weight
- 1
- 2
Tiedowns requirements
Use two tiedowns to secure one stack of shortwood loaded crosswise.
Attach the tiedowns to the vehicle frame at the front and rear of the load.
Position tiedowns approximately 1/3 and 2/3 of the length of the logs.
When securing metal coils in a sided vehicle without anchor points:
- Use locking and bracing
- Follow general cargo securement requirements
- All of these apply
- Use friction mats
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.
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 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.
- A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.
Container Chassis Vehicle:
A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
An anchor point is defined as:
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
- The load carrying area of a truck, trailer, or intermodal container.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
Anchor point:
Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
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.
