One option of positioning bundles of building materials is:
- Turn them so only their corners are touching.
- Lean them to the outside.
- Place them in direct contact with each other.
- Lean them against each other.
Choose one of two options for positioning bundles:
-
Option #1:
Place bundles in direct contact with each other.
-
Option #2:
Provide a means (such as dunnage or blocking) to prevent the bundles from shifting towards each other.
When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
- Straight up and down
- It doesn't matter
- Forward
- Rearward
Requirements for securing the pipe
Secure each pipe with tiedowns through the pipe.
Run at least one tiedown through each pipe in the front half of the load. This includes the middle one if there are an odd number. The tiedown must run rearward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable.
Run at least one tiedown through each pipe in the rear half of the load. The tiedown must run forward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable. This holds each pipe firmly in contact with adjacent pipe.
To secure paper rolls with eyes horizontal against rearward movement, you can use which of the following except:
- The vehicle wall.
- Other cargo.
- Blocking.
- Friction mats.
Direction of Potential Movement: Rearward
Methods to Prevent Movement:
- Other cargo
- Blocking
- Fiction mats
- Tiedowns
What is the minimum Working Load Limit for the entire securement system?
- 20% of cargo weight.
- 100% of cargo weight.
- 50% of cargo weight.
- 80% of cargo weight.
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.
What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
- 2,268 lbs
- It depends on how they're loaded
- 10,000 lbs
- 5,000 lbs
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
Who is responsible for inspecting securing devices and cargo within the first 50 miles?
- The driver.
- Your Moms.
- The D.O.T.
- The shipper.
Inspect Cargo and Securing devices:
- Pre-Trip: Yes
- Within first 50 mi: Yes
- When duty status of driver changes: Yes
- At 3 hour intervals or every 150 mi, whichever is first: Yes
What is the minimum aggregate WLL for a group of concrete pipe weighing 16,000 lbs?
- 7,999 lbs
- 8,001 lbs
- 10,000 lbs
- 5,000 lbs
General tiedown requirements
The aggregate working load limit of all tiedowns on any group of pipe must be more than half the total weight of all pipes in the group.
When loading paper rolls with eyes horizontal, which of the following is not a requirement for stacking a second layer:
- The bottom layer must extend all the way to the front.
- It must be blocked against an eye-vertical blocking roll resting on the floor of the vehicle that is at least 1.5 times taller than the diameter of the roll being blocked.
- All the wells in the layer beneath must be filled
- Place second layer with eyes vertical.
Requirements for eyes crosswise: secure stacks of paper rolls from front-to-back movement
- Do not load paper rolls on a second layer unless the bottom layer extends to the front of the vehicle.
- Load paper rolls on higher layers only if all wells in the layer beneath are filled.
-
Secure the foremost roll in each upper layer (or any roll with an empty well in front of it) against forward movement:
- Either by placing it in a well formed by two rolls on the lower row whose diameter is equal to or greater than that of the roll on the upper row.
- Or by banding it to other rolls.
- Or by blocking it against an eye-vertical blocking roll resting on the floor of the vehicle that is at least 1.5 times taller than the diameter of the roll being blocked.
Aggregate Working Load Limit is defined as:
- The maximum weight of a load of rocks that a securement device can withstand.
- The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
- 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).
- 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.
Aggregate Working Load Limit:
The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.

- 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 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

- 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.
