CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!An intermodal container is:
- 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 transport.
- 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 platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")

When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
- Forward
- Straight up and down
- It doesn't matter
- Rearward
Requirements for securing the pipe
Secure each pipe with tiedowns through the pipe.
Run at least one tiedown through each pipe in the front half of the load. This includes the middle one if there are an odd number. The tiedown must run rearward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable.
Run at least one tiedown through each pipe in the rear half of the load. The tiedown must run forward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable. This holds each pipe firmly in contact with adjacent pipe.
All of these are requirements for securing longwood lengthwise except:
- Each end of the log should extend at least 3 inches beyond the stakes.
- 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.
- Secure each log with at least two tiedowns if shorter logs are carried on top of the stack.
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.
- If shorter logs are carried on top of the stack, secure each log with at least two tiedowns.
What is the maximum weight that can be secured by a tiedown with a marked WLL of 5,000 lbs?
- 6,000 lbs
- 5,000 lbs
- 2,500 lbs
- 10,000 lbs
Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.
When securing rolls of paper with eyes vertical, how many points of contact are required to consider a roll secure?
- 2
- 4
- 1
- 3
Usually the roll is secure if a paper roll has 3 well-separated points of contact with the vehicle, other rolls, or other cargo.
If you were instructed to 'tarp' a load, what would you be using?
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself.
- A platform or tray on which cargo is placed so that it can be handled as an article.
- A waterproof sheet used to cover cargo.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
Tarp:
A waterproof sheet used to cover cargo.
When securing paper rolls with friction mats as a primary method:
- 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.
- The friction mat should stick out from underneath the roll in the opposite direction for which 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.
What is a rub rail?
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
- 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 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.
Rub Rail:
A rail along the side of a vehicle that protects the side of the vehicle from impacts.
When using tiedowns to secure boulders, all of the following are requirements except:
- Boulders must be loaded as far back towards the rear as possible.
- Use only chain to secure large boulders.
- Tiedowns should be located in valleys or notches across the top of the boulder.
- Tiedowns must be arranged to prevent sliding across the rock surface.
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.
When securing concrete pipe loaded crosswise, arrange the top tier:
- Any of these are acceptable.
- As a partial tier in two groups.
- As a complete tier.
- As a partial tier in one group.
Requirements for arranging the top tier
Arrange the top tier as a complete tier, a partial tier in one group, or a partial tier in two groups.
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

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.
