CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!When banding paper rolls with eyes vertical, you should:
- Secure bands with tape, hangers, or other means.
- Spread rolls apart from each other.
- All of these are necessary.
- Apply bands loosely.
Banding
If paper rolls are banded together:
- Place rolls tightly against each other to form a stable group.
- Apply bands tightly.
- Secure bands with tape, hangers, or other means so that the bands cannot fall off the rolls or slide down to the deck.
Banding is:
- 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 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).
- A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
- Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.

How many anchor points should be used to secure an intermodal container on a chassis vehicle?
- 2 latches in the middle, and 2 at the rear.
- 2 latches each at or near both the front and rear.
- 4 latches total, anywhere on the trailer.
- 2 latches in the front and 2 in the middle.
Secure the front and rear of the container independently.
- 2 latches on the chassis engage anchor points towards or at the front of the container.
- 2 latches on the chassis engage anchor points towards or at the rear of the container.
When securing building materials, how many tiedowns are required for top tier bundles longer than 5 ft?
- 1
- 0
- It depends on weight
- 2
Tiedowns over the top tier of bundles with a minimum of 2 tiedowns over each top bundle longer than 1.52 m (5 ft).
When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
- Forward
- Rearward
- Straight up and down.
- It doesn't matter.
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.
The narrowest end of a boulder should be pointed:
- It doesn't matter.
- Towards the sky.
- Towards the front of the vehicle.
- Towards the rear of the vehicle.
If a boulder is tapered, point the narrowest end towards the front of the vehicle.
When securing metal coils, it is acceptable to use nailed blocking or cleats as the sole means to secure:
- Nailed wood cradles
- Timbers
- It is not acceptable.
- Chocks
The use of nailed blocking or cleats as the sole means to secure timbers, chocks or wedges, or a nailed wood cradle, is prohibited.
When securing an intermodal container on a chassis, what is the maximum allowable vertical travel when secured?
- 2 1/2 inches
- 1 inch
- 2 inches
- 1/2 inch
Securing devices must restrain the container from moving more than:
- 1.27 cm (1/2 in) forward.
- 1.27 cm (1/2 in) rearward.
- 1.27 cm (1/2 in) to the right.
- 1.27 cm (1/2 in) to the left.
- 2.54 cm (1 in) vertically.
When securing a paper roll with a width that is more than twice its diameter, which of the following is not an acceptable method of securement to prevent tipping?
- Band the roll to other rolls.
- Use tiedowns.
- Use rear doors to brace it.
- Brace it.
Situation #1:
- Paper roll is not prevented from tipping by the vehicle structure or other cargo.
- Paper roll width is more than 2 times its diameter.
Solution #1:
- Either band the roll to other rolls.
- Or brace it.
- Or use tiedowns.
What types of freight need to be secured properly?
- Intermodal containers.
- All freight should always be properly secured while driving.
- Hazardous materials.
- Equipment used for vehicle operation.
-
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.

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.
