CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!Concrete pipe loaded crosswise generally:
- Note: At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
- At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
- Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.
- All of these things apply.
Special Circumstances: Securing Pipe with an Inside Diameter Up to 1.143 mm (45 in)
Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.
Note: This pipe diameter of 1.143 m (45 in) is simply a convenient breaking point between "medium" and "large" diameter pipe.
Note: At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
One option of positioning bundles of building materials is:
- Place them in direct contact with each other.
- Turn them so only their corners are touching.
- Lean them against each other.
- Lean them to the outside.
Choose one of two options for positioning bundles:
-
Option #1:
Place bundles in direct contact with each other.
-
Option #2:
Provide a means (such as dunnage or blocking) to prevent the bundles from shifting towards each other.
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?
- Use tiedowns.

Situation #1:
- Paper roll is not prevented from tipping by the vehicle structure or other cargo.

Solution #1:
- Either band the roll to other rolls.
- Or brace it.
- Or use tiedowns.

North American Cargo Securement Standard
What does the Standard cover? (Section 1.1)
- Commercial vehicles (including a combination of vehicles) that are operated on a highway and have a gross vehicle rating over 4,500 kg (10,000 lb.)
Vehicles
Within the requirements for concrete pipe, which of these requires specific securement methods?
- Concrete pipe loaded cross-wise on a flatbed trailer.
- Concrete pipe that is grouped together into a single rigid article and may not roll.
- Concrete pipe eyes vertical and concrete pipe loaded lengthwise.
- Concrete pipe loaded in a sided vehicle or container.
What is exempt from these specific requirements?
Follow general cargo securement requirements (Section 2) when transporting the following pipe:
- Concrete pipe that is grouped together into a single rigid article and may not roll.
- Concrete pipe loaded in a sided vehicle or container.
- Concrete pipe eyes vertical and concrete pipe loaded lengthwise.
What is covered under these specific requirements?
Any concrete pipe loaded crosswise on a platform trailer or vehicle that is not exempt.
Requirements for securing heavy vehicles, equipment, and machinery apply at what weight?
- Less than 10,000 lbs
- More than 4,500 lbs
- More than 10,000 lbs
- 50% the weight of the trailer
What Does This Section Cover?
The requirements in this section apply to the transportation of heavy vehicles, equipment, and machinery that:
- Operate on wheels or tracks, such as front end loaders, bulldozers, tractors, and power shovels.
- Individually weigh more than 4500 kg (10,000 lb.).
In cargo securement, what is a 'cleat' defined as?
- A tapered piece of material, thick at one end and thin at the other.
- 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.
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
Cleat:
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
What is the minimum securement requirement for paper rolls with eyes vertical with a width between 1.25 and 1.76 its diameter?
- Banding them together.
- All of these are required.
- Tiedowns.
- Friction mats alone.
Situation #4
- A paper roll or the forwardmost roll(s) in a group of paper rolls is not prevented from tipping or falling forward by vehicle structure or other cargo.
- Paper roll width is more than 1.25 times and less than 1.76 times its diameter.
- Only friction mats are used for forward securement.
Solution #4:
The friction mat alone is adequate. The friction mat allows the roll to slide on the floor without tripping the roll.

- 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

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.
