Go!All of these are requirements for securing longwood lengthwise except:
- Each end of the log should extend at least 3 inches beyond the stakes.
- Each outside log should bear against at least two stakes, one near each end of the log.
- Must be cradled in two or more bunks or contained by stakes.

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.

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.
- 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.
- 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 using tiedowns to secure boulders, all of the following are requirements except:
- Tiedowns must be arranged to prevent sliding across the rock surface.
- Use only chain to secure large boulders.
- Boulders must be loaded as far back towards the rear as possible.
- Tiedowns should be located in valleys or notches across the top of the boulder.
Requirements
Use only chain to secure large boulders.
Tiedowns in direct contact with the boulder:
Should be located in valleys or notches across the top of the boulder
Must be arranged to prevent sliding across the rock surface.
What is the minimum amount of rearward force that a cargo securement system must withstand?
- 50% of cargo weight
- 20% of cargo weight
- 80% of cargo weight
- 100% of cargo weight
Each cargo securement system must be able to withstand a minimum amount of force in each direction.
- Forward Force = 80% of cargo weight when braking while driving straight ahead.
- Rearward Force = 50% of cargo weight when accelerating, shifting gears while climbing a hill, or braking in reverse.
- Sideways Force = 50% of cargo weight when turning, changing lanes, or braking while turning.
-
Upward Force = 20% of cargo weight when traveling over bumps in the road or cresting a hill.
- This requirement is satisfied when the cargo is "Fully Contained."
A hook-lift container is:
- A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.
- A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.
- A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
- The load carrying area of a truck, trailer, or intermodal container.

What is a headboard?
- 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 vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
- A transverse load bearing structural component, particularly a part of a log bunk.
Headboard:
A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
A sided vehicle containing cargo weighing 35,980 lbs must be able to withstand a rearward force of at least:
- 17,990 lbs
- 28,784 lbs
- 10,000 lbs
- 36,000 lbs
Note: If the cargo is contained in a sided vehicle, the vehicle structure MUST be strong enough to withstand the forces described earlier.
- Forward force: 0.8 g (80%)
- Rearward force: 0.5.g (50%)
- Sideways force: 0.5 g (50%)
Which of the following can be used as part of the cargo securement system?
- Vehicle structure.
- Blocking and bracing equipment.
- All of these are valid.
- Securing devices.
What is a securement system?
A securement system is a securement method that uses one or a combination of the following elements:
- Vehicle Structure.
- Securing Devices.
- Blocking and Bracing Equipment.
What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
- 2,268 lbs
- 10,000 lbs
- It depends on how they're loaded
- 5,000 lbs
The rules in this section apply to shipments of paper rolls, which individually or together, weigh 2268 kg (5000 lb.) or more.
Note: Shipments of paper rolls that weigh less than 2268 kg (5000 lb.), and paper rolls that are unitized on a pallet may either be secured in accordance this section or with the general cargo securement requirements
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

- 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.
