CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!When securing building materials, how many knots are acceptable in the tiedown(s)?
- Depends on the weight of the cargo.
- 0
- 2
- 1
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.
What is bell pipe concrete?
- Pipe whose flanged end is of smaller diameter than its barrel.
- Pipe whose flanged end is of larger diameter than its barrel.
- Concrete used to make bell pipe.
- Pipe used to make concrete bells.
Bell Pipe Concrete:
Pipe whose flanged end is of larger diameter than its barrel.
In terms of cargo securement, what is a 'well'?
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
- 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 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.
Well:
The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
The aggregate WLL for logs loaded lengthwise must be at least:
- 1/6 the weight of the stack.
- 4,000 lbs
- 1/2 the weight of the stack.
- 1/2 the weight of the load.
Working load limit for longwood and shortwood loaded lengthwise
The aggregate working load limit for all tiedowns must be no less than 1/6 the weight of the stack of logs.
Note: This requirement is much less than the general requirement of an aggregate working load limit equal to 1/2 the weight of the load. This lowered requirement recognizes that the bunks/stakes help to prevent slippage.
When securing building materials, how many tiedowns are required for top tier bundles longer than 5 ft?
- 2
- It depends on weight
- 0
- 1
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 bell pipe in multiple complete tiers, all of the following are true except:
- Bells of the bottom tier must all be on the same side of the vehicle
- All of these apply.
- Stack the tiers in pyramid fashion.
- Bells of the upper tiers must all be on the opposite side of the vehicle from the bells of the tier below.
More than one tier with complete tiers
Bells of the bottom tier must all be on the same side of the vehicle
Bells of the upper tiers must be are on the opposite side of the vehicle from the bells of the tier below.
When securing a single metal coil with eyes vertical:
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
- These are all requirements.
- Attach at least one tiedown over eye of coil from side-to-side.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
To prevent the coil from tipping forward, rearward, and sideways, arrange tiedowns to include the following:
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
Which of the following is not a requirement of wood used as blocking or bracing?
- It should be properly seasoned.
- Hardwood is recommended.
- It should be free of decay and structural defects.
- It should be painted.
If wood is used:
- Hardwood is recommended.
- It should be properly seasoned.
- It should be free from rot or decay, knots, knotholes, and splits.
When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
- It doesn't matter.
- 90 degrees.
- Less than 45 degrees.
- Between 45 and 60 degrees.
The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
What is the presumed resistance to horizontal movement of friction mats?
- 50% of cargo weight.
- 100% of cargo weight.
- 0
- 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.
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.
