CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!'Blocking' is defined as:
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
Methods of securing building materials against forward motion include:
- Employing blocking equipment.
- These are all valid methods.
- Placing bundles against the bulkhead or front end.
- Using tiedowns.
-
Option #1
Place bundles against bulkhead/front end structure.
-
Option #2
When different tiers need to be secured, use a combination of blocking equipment and tiedowns.
When securing building materials, spacer requirements include all of the following except:
- The height of each spacer must be equal or greater than the width.
- If spacers are comprised of layers of material, the layers must be unitized or fastened together to ensure that the spacer performs as a single piece of material.
- The length of spacers must provide support to all pieces in the bottom row of the bundle.
- Spacers must provide good interlayer friction.
Spacer Requirements

- The width of each spacer must be equal or greater than the height.
- Spacers must provide good interlayer friction.
- If spacers are comprised of layers of material, the layers must be unitized or fastened together to ensure that the spacer performs as a single piece of material.
If you were instructed to 'tarp' a load, what would you be using?
- A platform or tray on which cargo is placed so that it can be handled as an article.
- A waterproof sheet used to cover cargo.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself.
Tarp:
A waterproof sheet used to cover cargo.
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 is a:
- Stake pocket
- Bulkhead
- Cleat
- Void filler
Stake Pocket:
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.
What is the minimum requirement for securing roll-off and hook containers?
- All of these are acceptable.
- Two tiedowns installed lengthwise, each securing one side of the container to one of the vehicle's side rails.
- One tiedown attached to both the vehicle chassis and the container chassis.
- Two hooks, or an equivalent mechanism, securing both sides of the container to the vehicle chassis.
Secure to the rear of the vehicle with at least one of the following three mechanisms:
-
Rear Mechanism 1:
One tiedown attached to both the vehicle chassis and the container chassis.
-
Rear Mechanism 2:
Two tiedowns installed lengthwise, each securing one side of the container to one of the vehicle's side rails.
-
Rear Mechanism 3:
Two hooks, or an equivalent mechanism, securing both sides of the container to the vehicle chassis at least as effectively as the tiedowns in the two previous items.
The Aggregate Working Load Limit should, at minimum, be:
- Determined by the shipper.
- 80% of the weight of the cargo.
- 100% of the weight of the cargo.
- 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.
Option #3 for securing metal coils transported with eyes lengthwise includes all of the following except:
- Attaching at least one tiedown over the top of the coil near the front of the coil.
- Attaching at least two tiedowns through the center of the coil.
- Attaching at least one tiedown over the top of the coil near the rear of the coil.
- Using blocking or friction mats to prevent forward movement.
Tiedowns, Single Coil Option #3
Option #3 is the same as Options #1 and #2, except that the two tiedowns that attach through the eye of the coil are replaced with two tiedowns that pass over the front and the rear of the coil.
Attach at least one tiedown over the top of the coil near the front of the coil.
Attach at least one tiedown over the top of the coil near the rear of the coil.
Use blocking or friction mats to prevent forward movement.
How many knots are acceptable in a properly working tiedown?
- 0
- 1
- 2
- 3
All components of a tiedown must be in proper working order.
- No knots or obvious damage
- No distress
- No weakened parts
- No weakened sections
A container chassis vehicle is defined as:
- A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.
- A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
- 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.
Container Chassis Vehicle:
A vehicle especially built and fitted with locking devices for the transport of intermodal containers.

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.
