If the cargo is fully contained in a sided vehicle, what is the minimum requirement for withstanding sideways force?

  • 0.8g (80% of cargo weight)
  • 0.7g (70% of cargo weight)
  • 0.5g (50% of cargo weight)
  • 0.2g (20% of cargo weight)

Note: If the cargo is contained in a sided vehicle, the vehicle structure MUST be strong enough to withstand the forces described earlier.

  • Forward force: 0.8 g (80%)
  • Rearward force: 0.5.g (50%)
  • Sideways force: 0.5 g (50%)

Cargo securement for a load weighing 37,000 lbs must be able to withstand a minimum forward braking force of:

  • 7,400 lbs
  • 10,000 lbs
  • 29,600 lbs
  • 18,500 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."
37,000 x 80% = 29,600 lbs.

A container chassis vehicle is defined as:

  • 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.
  • 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 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.

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.
