CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!The narrowest end of a boulder should be pointed:
- It doesn't matter.
- Towards the rear of the vehicle.
- Towards the front of the vehicle.
- Towards the sky.
If a boulder is tapered, point the narrowest end towards the front of the vehicle.
When securing paper rolls with friction mats as a primary method:
- The friction mat should stick out from underneath the roll in the opposite direction for which it is providing securement.
- All of these answers.
- The friction mat should stick out from underneath the roll in the direction it is providing securement.
- Make sure friction mats are completely covered by the roll.
Requirements for friction mats
If a friction mat is used to provide the principal securement for a paper roll, insert the friction mat so that it sticks out from beneath the footprint of the roll in the direction in which it is providing securement.
What types of freight need to be secured properly?
- Equipment used for vehicle operation.
- All freight should always be properly secured while driving.
- Intermodal containers.
- Hazardous materials.
-
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.
Cargo
When securing rolls of paper with eyes vertical, how many points of contact are required to consider a roll secure?
- 2
- 4
- 3
- 1
Usually the roll is secure if a paper roll has 3 well-separated points of contact with the vehicle, other rolls, or other cargo.
As part of their pre-trip cargo securement inspection, drivers should:
- Inform carrier of any inadequate packaging.
- All of these apply.
- Check for anything that will obscure their vision.
- Make sure cargo is properly secured.
Driver inspection checklist:
Pre-Trip
- Make sure that cargo is properly distributed and adequately secured (in other words, according to the Standard).
- Make sure that all securement equipment and vehicle structures are in good working order and used consistent with their capability.
- Stow vehicle equipment.
- Make sure that nothing obscures front and side views or interferes with the ability to drive the vehicle or respond in an emergency.
-
Inform carrier if packaging is not adequate. For example:
- Banding is loose or not symmetrical on package.
- Banding attachment device(s) are inefficient.
- Wrapping is broken or ineffective.
- Pallets are broken.
Which of the following is not true of Working Load Limit (WLL)?
- The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system.
- The WLL is usually assigned by the component manufacturer.
- All of these are true.
- The minimum WLL requirement for the securement system is 25%.
The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system during normal service.
The WLL is usually assigned by the component manufacturer.
Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.
'Blocking' is defined as:
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- 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 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.
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 is:
- Void filler.
- A friction mat.
- A cleat.
- A chock.
Friction mat:
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.
In cargo securement, what is a 'cleat' defined as?
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
- A tapered piece of material, thick at one end and thin at the other.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
Cleat:
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
Which of the following is not an acceptable method of containing loose parts when securing flattened or crushed vehicles?
- Sideboards or sides.
- Wedge them in between the flattened cars.
- Structural walls.
- Suitable covering material.
Containing Loose Parts
Use a containment system that:
- Prevents loose parts from falling from all four sides of the vehicle AND
- Extends to the full height of the cargo.
The containment system can consist of one or a combination of the following methods.
- Structural walls.
- Sides or sideboards.
- Suitable covering material.
The use of synthetic material for containment of loose parts is permitted.
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.
