Securement Requirements
Transport flattened or crushed vehicles so that:

- Loose parts from the flattened vehicles do not dislodge and fall from the transport vehicle
Do not use synthetic webbing to secure vehicles.
The Aggregate Working Load Limit should, at minimum, be:

- 80% of the weight of the cargo.
- Determined by the shipper.
- 100% of the weight of the cargo.
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.
A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces is:
- A cleat.
- A friction mat.
- Void filler.
- A chock.
Friction mat:
A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.
When loading bell pipe on one tier, all of the following apply except:
- Load bell pipe on one tier so that the bells all lie on one side of the vehicle.
- If the ends cannot be staggered, they must be aligned.
- If possible, the ends of consecutive pipe must be staggered within the allowable width.
- Load bell pipe on one tier so that the bells alternate on opposite sides 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.
Option #1 for securing coils transported with eyes lengthwise includes:

- Attaching at least one tiedown diagonally from the right side of the vehicle, through the eye, to the left side of the vehicle
Tiedowns, Single Coil Option #1
Attach at least one tiedown diagonally from the left side of the vehicle, through the eye, to the right side of the vehicle. If possible, the angle between the tiedown and the deck should be less than 45, when viewed from the side of the vehicle.
Attach at least one tiedown diagonally from the right side of the vehicle, through the eye, to the left side of the vehicle. If possible, the angle between the tiedown and the deck should be less than 45, when viewed from the side of the vehicle.
Attach at least one tiedown side-to-side over the top of the coil.
Use blocking or friction mats to prevent forward 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.
