- Concrete pipe loaded in a sided vehicle or container.
- Concrete pipe eyes vertical and concrete pipe loaded lengthwise.
What is covered under these specific requirements?
Any concrete pipe loaded crosswise on a platform trailer or vehicle that is not exempt.
Which of the following is not a method of securing side-by-side cargo?
- Fill the empty space between with other cargo.
- Place them in direct contact with each other.
- Make sure it is leaning forward.
- Use some kind of blocking to prevent shifting.
For articles of cargo placed beside each other and secured by side-to-side tiedowns:
Either place them in direct contact with each other,
Or prevent them from shifting towards each other in transit by using blocking or filling the space with other cargo.
When securing concrete pipe up to 45 inches loaded crosswise, tiedowns through the pipe must be:
- Chains
- Wire.
- Nylon rope.
- Straps.
Tiedown requirements
- Pipe may be secured individually or as a group.

- Void filler.
- A friction mat.
- A cleat.
- 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.
All of the following are requirements for transporting coils with eyes crosswise except:
- Attach one tiedown rearward
- Attach one tiedown forward
- These are all requirements
- Prevent the coil from rolling
There are three requirements for coils transported with eyes crosswise:
Prevent the coil from rolling
Attach one tiedown forward.
Attach one tiedown rearward.
A tiedown is defined as:
- 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 strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
- 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 or around an article to prevent horizontal movement of the article.
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).
Option #1 for securing coils transported with eyes lengthwise includes:
- It should include all of these things
- Attaching at least one tiedown diagonally from the right side of the vehicle, through the eye, to the left side of the vehicle
- Using blocking or friction mats to prevent forward movement.
- Attaching at least one tiedown diagonally from the left side of the vehicle, through the eye, to the right 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.
What is a pallet used for?
- A waterproof sheet used to cover cargo.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A vertical barrier across a vehicle to prevent forward movement of cargo.
- A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
Pallet:
A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
When securing paper rolls with friction mats as a primary method:
- Make sure friction mats are completely covered by the roll.
- The friction mat should stick out from underneath the roll in the direction it is providing securement.
- The friction mat should stick out from underneath the roll in the opposite direction for which it is providing securement.
- All of these answers.
Requirements for friction mats
If a friction mat is used to provide the principal securement for a paper roll, insert the friction mat so that it sticks out from beneath the footprint of the roll in the direction in which it is providing securement.
When securing paper rolls with eyes crosswise, which of the following can be used to prevent side-to-side shifting when there is more than 8 inches of space to the wall?
- Friction mats.
- Any of these methods are acceptable.
- Tiedowns.
- Void fillers.
Requirements for eyes crosswise: prevent rolls from shifting toward either wall
If there is more than a total of 203 mm (8 in) of space between the ends of a paper roll and other rolls or the walls of the vehicle, use one of these methods:
- Void fillers (such as honeycomb)
- Blocking
- Bracing
- Friction mats
- Tiedowns
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.
