CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!A chock is defined as:
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A crosswise load bearing structural component, particularly a part of a log bunk.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.

- 2
- 0
All components of a tiedown must be in proper working order.

What types of freight need to be secured properly?
- All freight should always be properly secured while driving.
- Equipment used for vehicle operation.
- Intermodal containers.
- Hazardous materials.
-
Any cargo and dangerous goods/hazardous materials, including:
- All general freight.
- All equipment carried for vehicle operation.
- Intermodal containers and their contents.
- Some specific commodities have additional or different securement requirements (see later sections of this Handbook).
- Additional requirements under separate regulations may also apply for transportation of certain types of dangerous goods or hazardous materials.
Cargo
Which of the following is not a requirement for shortwood loaded lengthwise?
- Heavier logs must be stacked on top.
- Must be cradled in a bunk or contained by stakes.
- Logs should be centered in the bunk.
- Each outside log bearing against stakes should extend at least 6 in beyond the stakes at each end.
Requirements for shortwood loaded lengthwise
- Shortwood must be cradled in a bunk or contained by stakes.
- Logs should be centered in the bunk.
- Each outside log bearing against stakes should extend at least 0.15 m (6 in) beyond the stakes at each end.
Cargo is contained when:
- It is loaded on the end of the truck.
- It is packed in a square box.
- It fills a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
- 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.
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.
In case of low friction between the cargo and deck, which of these is not a solution?
- Attach tiedowns to the cargo.
- Put something heavy on top of the cargo.
- Use some kind of blocking.
- Set the cargo on friction mats.
What should you use in low-friction situations?
When there is low friction between the cargo and the deck (for example, with snow, ice, sand, gravel, and oil):
- Use tiedowns attached to the cargo.
- Use a means to improve the friction such as friction mats or tiedown that pass over the cargo.
- Use blocking and tiedowns.
When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
- 90 degrees.
- Between 45 and 60 degrees.
- Less than 45 degrees.
- It doesn't matter.
The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
Which of the following is not a method of securing side-by-side cargo?
- Make sure it is leaning forward.
- Use some kind of blocking to prevent shifting.
- Fill the empty space between with other cargo.
- Place them in direct contact with each other.
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.
What is the minimum aggregate WLL of all tiedowns in a group of concrete pipe?
- More than 50% of the total weight of all pipes in the group.
- 5,000 lbs.
- 80% of the total weight of all pipes in the group.
- It depends on the size of the pipe.
General tiedown requirements
The aggregate working load limit of all tiedowns on any group of pipe must be more than half the total weight of all pipes in the group.
In terms of cargo securement, what is a 'well'?
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
- A female housing fixed to the side or ends of a vehicle to receive a stake or peg, and may also be used as an anchor point.
- 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.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
Well:
The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
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.
