As part of their pre-trip cargo securement inspection, drivers should:
- Check for anything that will obscure their vision.
- Inform carrier of any inadequate packaging.
- Make sure cargo is properly secured.
- All of these apply.
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.
What is the minimum WLL required of tiedowns securing loaded intermodal containers on non-chassis vehicles?
- 50% of the loaded weight of the container.
- It depends on the length of the container.
- 20% of the loaded weight of the container.
- 80% 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.
When securing paper rolls with eyes vertical in a sided vehicle all of the following are acceptable except:

- Each other
- Other cargo
When securing concrete pipe with a diameter up to 45 inches loaded crosswise as a group,lengthwise tiedowns should be either one 1/2 in chain or wire rope, or:

- One 3/8 inch chain or wire rope.
- Two 1/4 inch chains or wire ropes.
As a group
Place lengthwise tiedowns over the group of pipes:
Either one 13 mm (1/2 in) chain or wire rope,
Or two 10 mm (3/8 in) diameter chain or wire rope
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 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.
Who is responsible for inspecting securing devices and cargo within the first 50 miles?
- The driver.
- The D.O.T.
- The shipper.
- Your Moms.
Inspect Cargo and Securing devices:
- Pre-Trip: Yes
- Within first 50 mi: Yes
- When duty status of driver changes: Yes
- At 3 hour intervals or every 150 mi, whichever is first: Yes
What is a headboard?
- A vertical barrier across a vehicle to prevent forward movement of cargo.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A transverse load bearing structural component, particularly a part of a log bunk.
- A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
Headboard:
A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
All of these are requirements for securing longwood lengthwise except:
- Each end of the log should extend at least 3 inches beyond the stakes.
- Secure each log with at least two tiedowns if shorter logs are carried on top of the stack.
- Must be cradled in two or more bunks or contained by stakes.
- Each outside log should bear against at least two stakes, one near each end of the log.
Requirements for securing longwood loaded lengthwise
- Longwood must be cradled in two or more bunks or contained by stakes.
- Each outside log should bear against at least two stakes, one near each end of the log.
- Each end of the log should extend at least 0.15 m (6 in) beyond the stakes.
- If shorter logs are carried on top of the stack, secure each log with at least two tiedowns.
When using tiedowns for securing cargo, what is the general rule regarding cargo length.
- 1 tiedown for every 10 ft, or part thereof.
- 1 tiedown for every 15 ft, or part thereof.
- 1 tiedown for every 5 ft, or part thereof.
- 2 tiedowns for every 10 ft, or part thereof.
When cargo is prevented from forward movement (for example, by the headboard, bulkhead, other cargo, or tiedown), secure the cargo according to the following requirements:
All Cargo:
1 tiedown for every 10 ft, or part thereof.
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.
