As part of their pre-trip cargo securement inspection, drivers should:

  • Check for anything that will obscure their vision.
  • Inform carrier of any inadequate packaging.
  • All of these apply.
  • 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.

  • Spacers must provide good interlayer friction.
  • The length of spacers must provide support to all pieces in the bottom row of the bundle.

Concrete pipe loaded crosswise generally:

  • Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.
  • Note: At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
  • At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
  • All of these things apply.

Special Circumstances: Securing Pipe with an Inside Diameter Up to 1.143 mm (45 in)

Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.

Note: This pipe diameter of 1.143 m (45 in) is simply a convenient breaking point between "medium" and "large" diameter pipe.

Note: At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.

At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.

  • Wrap chains around the circumference of the boulder.
  • Pass the tiedowns over the center of the boulder
  • Secure each boulder individually with at least two chain tiedowns forming an X pattern over the boulder.

Secure each boulder individually with at least two chain tiedowns forming an X pattern over the boulder.

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
  • Pocket
  • 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.
