CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!When calculating directional forces, 'g' is expressed as:
- The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
- The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.
- The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
- The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.

To prevent rolling, how many points of contact are required, at minimum, for a boulder resting on a rounded or partially rounded side?
- 4
- 2

- 5
Requirements
If the flattest side of the boulder is rounded or partially rounded, place the boulder in a crib made of hardwood fixed to deck of vehicle.
Boulder should rest on both deck and timber, with at least 3 well-separated points of contact that prevent rolling in any direction.
Option #1 for securing coils transported with eyes lengthwise includes:
- Attaching at least one tiedown diagonally from the left side of the vehicle, through the eye, to the right side of the vehicle
- It should include all of these things
- Using blocking or friction mats to prevent forward movement.
- Attaching at least one tiedown diagonally from the right side of the vehicle, through the eye, to the left side of the vehicle
Tiedowns, Single Coil Option #1
Attach at least one tiedown diagonally from the left side of the vehicle, through the eye, to the right side of the vehicle. If possible, the angle between the tiedown and the deck should be less than 45, when viewed from the side of the vehicle.
Attach at least one tiedown diagonally from the right side of the vehicle, through the eye, to the left side of the vehicle. If possible, the angle between the tiedown and the deck should be less than 45, when viewed from the side of the vehicle.
Attach at least one tiedown side-to-side over the top of the coil.
Use blocking or friction mats to prevent forward movement.
When loaded cement pipe over 45 inches in diameter, which pipes should be blocked, wedged, or otherwise immobilized?
- Front and rear.
- It depends on the weight of the load.
- Front only.
- Rear only.
Immobilize the front and rear pipe with on of the following methods:
- Blocking
- Wedges
- Vehicle end structure
- Stakes
- Locked pipe unloader
- Other equivalent means
If you were instructed to 'tarp' a load, what would you be using?
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
- A waterproof sheet used to cover cargo.
- A platform or tray on which cargo is placed so that it can be handled as an article.
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself.
Tarp:
A waterproof sheet used to cover cargo.
When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
- Between 45 and 60 degrees.
- It doesn't matter.
- 90 degrees.
- Less than 45 degrees.
The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
When securing paper rolls with eyes horizontal, which of the following should be used to secure the rear-most roll?
- Secure blocking against rear doors.
- Wedges or chocks secured by some means in addition to friction.
- All of these are acceptable
- 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.
What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
- 10,000 lbs
- 5,000 lbs
- 2,268 lbs
- It depends on how they're loaded
The rules in this section apply to shipments of paper rolls, which individually or together, weigh 2268 kg (5000 lb.) or more.
Note: Shipments of paper rolls that weigh less than 2268 kg (5000 lb.), and paper rolls that are unitized on a pallet may either be secured in accordance this section or with the general cargo securement requirements
When securing metal coils with eyes vertical, the angle between tiedown and deck, if possible, should be:
- Between 60 and 90 degrees
- 60 degrees
- 180 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.
How many anchor points should be used to secure an intermodal container on a chassis vehicle?
- 2 latches in the middle, and 2 at the rear.
- 2 latches in the front and 2 in the middle.
- 4 latches total, anywhere on the trailer.
- 2 latches each at or near both the front and rear.
Secure the front and rear of the container independently.
- 2 latches on the chassis engage anchor points towards or at the front of the container.
- 2 latches on the chassis engage anchor points towards or at the rear of the container.

- Wire rope
- Manila rope
- Synthetic rope
- Steel strapping
- Clamps and latches
- Blocking
- Front-end structure

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.
