Choose A Section:
Go!Which of the following is not an acceptable method of containing loose parts when securing flattened or crushed vehicles?
- Wedge them in between the flattened cars.
- Suitable covering material.
- Structural walls.
- Sideboards or sides.
Containing Loose Parts
Use a containment system that:
- Prevents loose parts from falling from all four sides of the vehicle AND
- Extends to the full height of the cargo.
The containment system can consist of one or a combination of the following methods.
- Structural walls.
- Sides or sideboards.
- Suitable covering material.
The use of synthetic material for containment of loose parts is permitted.
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 opposite direction for which it is providing securement.
- All of these answers.
- The friction mat should stick out from underneath the roll in the direction it is providing securement.
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.
As part of the log packing requirements:
- Each inside log on the side of a stack of logs must touch at least two bunks, bolsters, stakes, or standards.
- Logs must be loosely packed.
- The center of the highest log on each side or end must be above the top of each stake, bunk, or standard.
- Outer bottom logs must be in contact with and rest solidly against bunks, bolsters, stakes, or standards.
Packing requirements
- Logs must be solidly packed.
- Outer bottom logs must be in contact with and rest solidly against bunks, bolsters, stakes, or standards.
-
Each outside log on the side of a stack of logs must touch at least two bunks, bolsters, stakes, or standards. If one end of the log doesn't touch a stake:
- It must rest on other logs in a stable manner.
- It must extend beyond the stake, bunk, bolster, or standard.
- The center of the highest log on each side or end must be below the top of each stake, bunk, or standard.

When securing concrete pipe with a diameter up to 45 inches loaded crosswise as a group, a crosswise tiedown should be used every how many feet?
- 15
- 10
- 3
- 6
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
Place one crosswise tiedown for every 3.0 m (10 ft) of load length.
Either attach the side-to-side tiedown through a pipe
Or pass the tiedown over both front-to-back tiedowns between two pipes on the top tier.
One option of positioning bundles of building materials is:
- Lean them against each other.
- Place them in direct contact with each other.
- Turn them so only their corners are touching.
- Lean them to the outside.
Choose one of two options for positioning bundles:
-
Option #1:
Place bundles in direct contact with each other.
-
Option #2:
Provide a means (such as dunnage or blocking) to prevent the bundles from shifting towards each other.
The definition for "shortwood" identifies pieces that are no longer than:
- 75 in
- Half the length of the trailer.
- 16 ft
- The width of the road.
Shortwood
- Normally up to about 2.5 m (100 in) in length.
- No longer than 4.9 m (16 ft) in length.
-
Also called:
- Cut-up logs
- Cut-to-length logs
- Bolts
- Pulpwood
An anchor point is defined as:
- The load carrying area of a truck, trailer, or intermodal container.
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
Anchor point:
Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
Within the requirements for concrete pipe, which of these requires specific securement methods?
- Concrete pipe loaded in a sided vehicle or container.
- Concrete pipe loaded cross-wise on a flatbed trailer.
- Concrete pipe that is grouped together into a single rigid article and may not roll.
- Concrete pipe eyes vertical and concrete pipe loaded lengthwise.
What is exempt from these specific requirements?
Follow general cargo securement requirements (Section 2) when transporting the following pipe:
- Concrete pipe that is grouped together into a single rigid article and may not roll.
- 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.
What is the maximum angle recommended for tiedowns securing cement pipe loaded crosswise, relative to the deck?
- 45-90 degrees
- 45 degrees
- It doesn't matter
- 180 degrees
If the first pipe of a group in the top tier is not at the front of the tier beneath:
Attach an additional tiedown that runs rearward at an angle not more than 45 to the horizontal when viewed from the side of the vehicle, whenever practical.
Pass tiedown either through the front pipe of the upper tier or outside the front pipe and over both longitudinal 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.
