CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!When banding paper rolls with eyes vertical, you should:
- All of these are necessary.
- Apply bands loosely.
- Spread rolls apart from each other.
- Secure bands with tape, hangers, or other means.
Banding
If paper rolls are banded together:
- Place rolls tightly against each other to form a stable group.
- Apply bands tightly.
- Secure bands with tape, hangers, or other means so that the bands cannot fall off the rolls or slide down to the deck.
When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
- It doesn't matter.
- Less than 45 degrees.
- Between 45 and 60 degrees.
- 90 degrees.
The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
Banding is:
- 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 device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
- 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).
- Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.

When securing metal coils with eyes vertical, the angle between tiedown and deck, if possible, should be:
- 180 degrees
- Between 60 and 90 degrees
- Less than 45 degrees
- 60 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.
When securing building materials, how many knots are acceptable in the tiedown(s)?
- 1
- 0
- Depends on the weight of the cargo.
- 2
Requirements for Securement System:
- In proper working order with no damaged or weakened components that affect their performance or reduce their working load limit.
- No knots.
- Attached and secured in a manner that prevents them from coming loose during transit.
- Able to be tightened by a driver of an in-transit vehicle.
- Located inboard of rub rails whenever practicable.
- Edge protection must be used when a tiedown would be subject to abrasion or cutting.
When securing flattened or crushed cars on a vehicle with containment on 2 sides, how many tiedowns, at minimum, are required?
- 3
- 4
- 2
- 1
Option 3:
Has containment walls on two sides that:
- Extend to the full height of the load.
- Block against cargo movement in the forward and rearward.
Secures each stack of vehicles with a minimum of three tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Which of the following is not true of Working Load Limit (WLL)?
- The WLL is usually assigned by the component manufacturer.
- All of these are true.
- The minimum WLL requirement for the securement system is 25%.
- The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system.
The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system during normal service.
The WLL is usually assigned by the component manufacturer.
Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.
Cargo is contained when:
- It fills a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
- It is loaded on the end of the truck.
- 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.
- It is packed in a square box.
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.
While driving, the freight must not:
- Obscure the driver's view ahead, left, or right.
- All of these things should be avoided.
- Interfere with the free movement of the driver's arms or legs.
- Prevent the exit of a person from the cab.
- Obscure the driver's view ahead or to the right or left sides (except for drivers of self-steer dollies).
- Interfere with the free movement of the driver's arms or legs.
- Prevent the driver's free and ready access to accessories required for emergencies. OR
- Prevent the free and ready exit of any person from the commercial motor vehicle's cab or driver's compartment.
When securing building materials, spacer requirements include all of the following except:
- The length of spacers must provide support to all pieces in the bottom row of the bundle.
- Spacers must provide good interlayer friction.
- The height of each spacer must be equal or greater than the width.
- If spacers are comprised of layers of material, the layers must be unitized or fastened together to ensure that the spacer performs as a single piece of material.

- Wire rope
- Manila rope
- Synthetic rope
- Steel strapping
- Clamps and latches

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.
