Option #3 for securing metal coils transported with eyes lengthwise includes all of the following except:
- Attaching at least one tiedown over the top of the coil near the front of the coil.
- Attaching at least two tiedowns through the center of the coil.
- Using blocking or friction mats to prevent forward movement.
- Attaching at least one tiedown over the top of the coil near the rear of the coil.
Tiedowns, Single Coil Option #3
Option #3 is the same as Options #1 and #2, except that the two tiedowns that attach through the eye of the coil are replaced with two tiedowns that pass over the front and the rear of the coil.
Attach at least one tiedown over the top of the coil near the front of the coil.
Attach at least one tiedown over the top of the coil near the rear of the coil.
Use blocking or friction mats to prevent forward movement.
The term 'edge protector' refers to:
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.
- A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
- 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.
Edge protector:
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.
When securing heavy vehicles, what is the minimum WLL of each tiedown?
- 5,000 lbs
- 10,000 lbs
- 50% of the weight of the cargo
- 2,268 lbs
- Restrain cargo using a minimum of four tiedowns, each having a WLL of at least 2,268 kg (5,000 lb.).
When securing concrete bell pipe in multiple complete tiers, all of the following are true except:
- Bells of the bottom tier must all be on the same side of the vehicle
- Stack the tiers in pyramid fashion.
- Bells of the upper tiers must all be on the opposite side of the vehicle from the bells of the tier below.
- All of these apply.
More than one tier with complete tiers
Bells of the bottom tier must all be on the same side of the vehicle
Bells of the upper tiers must be are on the opposite side of the vehicle from the bells of the tier below.
What is the minimum WLL required of tiedowns securing loaded intermodal containers on non-chassis vehicles?
- 80% of the loaded weight of the container.
- 50% of the loaded weight of the container.
- It depends on the length 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.
When banding paper rolls with eyes vertical, you should:
- Spread rolls apart from each other.
- All of these are necessary.
- Apply bands loosely.
- Secure bands with tape, hangers, or other means.
Banding
If paper rolls are banded together:
- Place rolls tightly against each other to form a stable group.
- Apply bands tightly.
- Secure bands with tape, hangers, or other means so that the bands cannot fall off the rolls or slide down to the deck.
What is bell pipe concrete?
- Pipe used to make concrete bells.
- Concrete used to make bell pipe.
- Pipe whose flanged end is of smaller diameter than its barrel.
- Pipe whose flanged end is of larger diameter than its barrel.
Bell Pipe Concrete:
Pipe whose flanged end is of larger diameter than its barrel.
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.

- 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.
