Go!In terms of cargo securement, what is a 'well'?
- 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.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- 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.
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
Well:
The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
When securing a single metal coil with eyes vertical:
- These are all requirements.
- 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 diagonally across eye of coil from left side of vehicle to right side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
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.

- The load carrying area of a truck, trailer, or intermodal container.
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
Anchor point:
Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
In cargo securement, a wedge is defined as:
- A tapered piece of material, thick at one end and thin at the other, used to help keep cargo from moving.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
Wedge:
A tapered piece of material, thick at one end and thin at the other, used to help keep cargo from moving.
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
- Stack the tiers in pyramid fashion.
- All of these apply.
- 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.
Which of the following is not a reason why loads should be secured?
- Avoid fines and citations
- Make it look pretty
- Prevent loss of load
- Prevent damage to the cargo
Why secure your load? To prevent:
- Loss of life
- Loss of load
- Damage to the cargo
- Damage to the vehicle
- Issuance of citations/fines to driver/carrier
- The vehicle being placed Out-of-Service.
- A crash
Cargo securement for a load weighing 37,000 lbs must be able to withstand a minimum forward braking force of:
- 7,400 lbs
- 18,500 lbs
- 29,600 lbs
- 10,000 lbs
How well must the securement system work? (Section 1.3)
Each cargo securement system must be able to withstand a minimum amount of force in each direction.
- Forward Force = 80% of cargo weight when braking while driving straight ahead.
- Rearward Force = 50% of cargo weight when accelerating, shifting gears while climbing a hill, or braking in reverse.
- Sideways Force = 50% of cargo weight when turning, changing lanes, or braking while turning.
-
Upward Force = 20% of cargo weight when traveling over bumps in the road or cresting a hill.
- This requirement is satisfied when the cargo is "Fully Contained."
The narrowest end of a boulder should be pointed:
- Towards the rear of the vehicle.
- Towards the front of the vehicle.
- It doesn't matter.
- Towards the sky.
If a boulder is tapered, point the narrowest end towards the front of the vehicle.
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:
- A chock.
- A friction mat.
- A cleat.
- Void filler.
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.
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.
