CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!Cargo is contained when:
- 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 is packed in a square box.
- It is loaded on the end of the truck.
- 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.
'Blocking' is defined as:
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.

A hook-lift 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 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 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.
Hook-lift Container:
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.
The Aggregate Working Load Limit should, at minimum, be:
- 100% of the weight of the cargo.
- 80% of the weight of the cargo.
- Determined by the shipper.
- 50% of the weight of the cargo.
How much should the Aggregate Working Load Limit be?
The aggregate working load limit of any securement system must be at least 50% of the weight of the cargo being secured.
If the cargo is fully contained in a sided vehicle, what is the minimum requirement for withstanding sideways force?
- 0.8g (80% of cargo weight)
- 0.5g (50% of cargo weight)
- 0.7g (70% of cargo weight)
- 0.2g (20% of cargo weight)
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%)
When securing concrete pipe loaded crosswise, arrange the top tier:
- As a complete tier.
- Any of these are acceptable.
- As a partial tier in two groups.
- 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.
What types of freight need to be secured properly?
- Hazardous materials.
- All freight should always be properly secured while driving.
- Equipment used for vehicle operation.
- Intermodal containers.
-
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
A sided vehicle containing cargo weighing 35,980 lbs must be able to withstand a rearward force of at least:
- 28,784 lbs
- 17,990 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 these are requirements for securement systems?
- Components should be in proper working order.
- These all qualify as requirements.
- If a tiedown would be subject to cutting or abrasion, edge protection should be used.
- There should be no knots in the tiedowns.
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.
