As part of their pre-trip cargo securement inspection, drivers should:
- Make sure cargo is properly secured.
- All of these apply.
- Inform carrier of any inadequate packaging.
- Check for anything that will obscure their vision.
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.
A tiedown is defined as:
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
- 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).
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.

- When total weight is less than 5,000 lbs.
Special Circumstances: Loading and Securing Paper Rolls on a Flatbed Vehicle or a Curtain-Sided Vehicle
Requirements for eyes vertical or with eyes horizontal and lengthwise
Load and secure the paper rolls as described for a sided vehicle.
Attach tiedowns to secure entire load according to the general cargo securement requirements in Section 2.
Note: Stacked loads of paper rolls with eyes vertical are prohibited
Which of the following is not a requirement for shortwood loaded lengthwise?

- Each outside log bearing against stakes should extend at least 6 in beyond the stakes at each end.
- Logs should be centered in the bunk.
Requirements for shortwood loaded lengthwise
- Shortwood must be cradled in a bunk or contained by stakes.
- Logs should be centered in the bunk.
- Each outside log bearing against stakes should extend at least 0.15 m (6 in) beyond the stakes at each end.
In terms of cargo securement, what is a 'well'?
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
- A female housing fixed to the side or ends of a vehicle to receive a stake or peg, and may also be used as an anchor point.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- 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.
Well:
The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
Banding is:
- 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).
- A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
- Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")

Vehicles
When securing a single metal coil with eyes vertical:
- These are all requirements.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
To prevent the coil from tipping forward, rearward, and sideways, arrange tiedowns to include the following:
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
In cargo securement, a wedge is defined as:
- A tapered piece of material, thick at one end and thin at the other, used to help keep cargo from moving.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.

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

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.
