Choose A Section:
Go!When securing paper rolls with eyes horizontal, which of the following should be used to secure the rear-most roll?
- All of these are acceptable
- Wedges or chocks secured by some means in addition to friction.
- Secure blocking against rear doors.
- Secure roll against rear doors.
Note: Chocks, Wedges, or Blocking Securing the Front or Rear Roll - Hold in place by some means in addition to friction so they cannot become unintentionally unfastened or loose while the vehicle is in transit. This is often accomplished with nails.
Requirements for eyes crosswise: secure rearmost roll
Do not secure the rearmost roll with:
- Either the rear doors of the vehicle or intermodal container
- Or blocking held in place by those doors.
A chock is defined as:
- A crosswise load bearing structural component, particularly a part of a log bunk.
- 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.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
Chock:
A tapered or wedge-shaped piece used to secure round articles against rolling.
When securing building materials, how many tiedowns are required for top tier bundles longer than 5 ft?
- It depends on weight
- 1
- 0
- 2
Tiedowns over the top tier of bundles with a minimum of 2 tiedowns over each top bundle longer than 1.52 m (5 ft).
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")

What is a pallet used for?
- A vertical barrier across a vehicle to prevent forward movement of cargo.
- A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A waterproof sheet used to cover cargo.
Pallet:
A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
Methods of securing building materials against forward motion include:
- Using tiedowns.
- Employing blocking equipment.
- Placing bundles against the bulkhead or front end.
- These are all valid methods.
-
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.
A container chassis vehicle is defined as:
- 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.
- 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.
Container Chassis Vehicle:
A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
Specific securement methods are required for boulders that:
- Weigh more than 5,000 lbs, or have a volume of more than 1.25 cubic meters.
- Weigh more than 5,000 lbs, or have a volume of more than 4 cubic meters.
- Weigh more than 11,000 lbs, or have a volume of more than 2 cubic meters.
- Have more than five distinct sides.
The requirements in this section apply to any piece of natural, irregularly shaped rock that:
Weighs more than 5,000 kg (11,000 lb.) or has a volume greater than two cubic meters
Is transported on an open vehicle or in a vehicle whose sides are not designed and rated for the transportation of boulders.
When securing metal coils with eyes vertical, the angle between tiedown and deck, if possible, should be:
- 180 degrees
- 60 degrees
- Between 60 and 90 degrees
- Less than 45 degrees
- Attach at least one tiedown against front of row of coils to restrain against forward motion. If possible, angle between tiedown and deck should be less than 45, when viewed from the side of the vehicle.
- Attach at least one tiedown against rear of row of coils to restrain against rearward motion. If possible, angle between tiedown and deck should be less than 45, when viewed from the side of the vehicle.
- Attach at least one tiedown over top of each coil or side-by-side row of coils to restrain against vertical motion. Tiedowns going over top of coil(s) must be as close as possible to eye of coil.
- Arrange tiedowns, blocking, or bracing to prevent shifting or tipping in all directions.
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

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.
