Rub Rail:
A rail along the side of a vehicle that protects the side of the vehicle from impacts.
When securing rows of coils, requirements include all of the following except:
- Attach at least one tiedown over the top of each coil or side-by-side row, located near the rear of the coil.

- Attach at least one tiedown over the top of each coil or side-by-side row, located near the front of the coil.
- Attach at least one tiedown through the center of each row of coils.
Tiedowns
Attach at least one tiedown over the top of each coil or side-by-side row, located near the front of the coil.
Attach at least one tiedown over the top of each coil or side-by-side row, located near the rear of the coil.

What is bell pipe concrete?
- Pipe whose flanged end is of larger diameter than its barrel.
- Pipe used to make concrete bells.
- Pipe whose flanged end is of smaller diameter than its barrel.
- Concrete used to make bell pipe.
Bell Pipe Concrete:
Pipe whose flanged end is of larger diameter than its barrel.
Which of these is specifically prohibited when securing crushed or flattened vehicles?
- Wire rope.
- Chains.
- Containment walls.
- Synthetic webbing.
Securement Requirements
Transport flattened or crushed vehicles so that:
- Cargo does not shift while in transit AND
- Loose parts from the flattened vehicles do not dislodge and fall from the transport vehicle
Do not use synthetic webbing to secure vehicles.
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 friction mats as a primary method:
- The friction mat should stick out from underneath the roll in the opposite direction for which it is providing securement.
- The friction mat should stick out from underneath the roll in the direction it is providing securement.
- All of these answers.
- Make sure friction mats are completely covered by the roll.
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 building materials, how many knots are acceptable in the tiedown(s)?
- 0
- 2
- 1
- Depends on the weight of the cargo.
Requirements for Securement System:
- In proper working order with no damaged or weakened components that affect their performance or reduce their working load limit.
- No knots.
- Attached and secured in a manner that prevents them from coming loose during transit.
- Able to be tightened by a driver of an in-transit vehicle.
- Located inboard of rub rails whenever practicable.
- Edge protection must be used when a tiedown would be subject to abrasion or cutting.
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.
