CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!Cargo is contained when:
- 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.
- 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.
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.
When securing an intermodal container on a chassis, what is the maximum allowable vertical travel when secured?
- 1 inch
- 2 1/2 inches
- 1/2 inch
- 2 inches
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 loading and securing a boulder, it should be:
- Placed on the vehicle with its largest or flattest side down.
- All of these are requirements.
- Placed on symmetrical hardwood blocking that extends 3/4 of the length of the boulder.
- Supported on at least 2 pieces of 4in x 4in hardwood blocking, extending the full width of the boulder.
Requirements
Place each boulder on the vehicle with its flattest and/or largest side down.
Support each boulder on at least two pieces of hardwood blocking (at least 10 cm x 10 cm (4 x 4 in) that extend the full width of the boulder.
Place hardwood blocking pieces as symmetrically as possible under the boulder so they support at least 3/4 of the length of the boulder.
The Aggregate Working Load Limit should, at minimum, be:
- 80% of the weight of the cargo.
- 100% 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.
What is the presumed resistance to horizontal movement of friction mats?
- 0
- 50% of cargo weight.
- 100% of cargo weight.
- 20% of cargo weight.
Note: Friction mats, which are not marked by the manufacturer, are assumed to provide a resistance to horizontal movement equal to 50% of the cargo weight that is resting on the mat.
All of the following are requirements for transporting coils with eyes crosswise except:
- These are all requirements
- Attach one tiedown rearward
- Prevent the coil from rolling
- Attach one tiedown forward
There are three requirements for coils transported with eyes crosswise:
Prevent the coil from rolling
Attach one tiedown forward.
Attach one tiedown rearward.
What is a rub rail?
- 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.
- 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 platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
Rub Rail:
A rail along the side of a vehicle that protects the side of the vehicle from impacts.
What is the minimum WLL of each tiedown used to secure crushed or flattened vehicles?
- It depends on the vehicle
- 2,268 lbs
- 5,000 lbs
- 10,000 lbs
Option 2:
Has containment walls on three sides that:
- Extend to the full height of the load
- Block against cargo movement in the forward, rearward, and one sideways direction.
Secures each stack of vehicles with a minimum of two tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Option 3:
Has containment walls on two sides that:
- Extend to the full height of the load.
- Block against cargo movement in the forward and rearward.
Secures each stack of vehicles with a minimum of three tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Option 4:
Has a minimum of four tiedowns per vehicle stack with each tiedown having a minimum WLL of 2,268 kg (5,000 lb.).
The term 'edge protector' refers to:
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- 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.
- A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.
- A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
Edge protector:
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.
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 short piece of material, usually wood, nailed to the deck to reinforce blocking.
- A waterproof sheet used to cover cargo.
- A platform or tray on which cargo is placed so that it can be handled as an article.
Tarp:
A waterproof sheet used to cover cargo.
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.

- 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.
