Go!A dunnage bag is:
- A transverse load bearing structural component, particularly a part of a log bunk.
- An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
- A waterproof sheet used to cover cargo.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
Dunnage bag:
An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
If the cargo is fully contained in a sided vehicle, what is the minimum requirement for withstanding sideways force?
- 0.5g (50% of cargo weight)
- 0.8g (80% of cargo weight)
- 0.7g (70% 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%)
Which of the following are not covered by the specific log securement requirements?
- Firewood, stumps, debris, other short logs, and longer logs.
- Logs unitized by banding or other comparable means.
- None of these are covered by the specific log requirements
- Loads of no more than four processed logs.
The following types of logs are not covered by the specific logs requirements:
- Logs unitized by banding or other comparable means. [Secure according to general cargo securement requirements.]
- Loads of no more than four processed logs. [Secure according to general cargo securement requirements.]
- Firewood, stumps, debris, other short logs, and longer logs. [Transport in a vehicle or container enclosed on both sides, the front, and the rear and strong enough to contain them.]
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.
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.
When securing an intermodal container on a chassis, what is the maximum allowable vertical travel when secured?
- 1 inch
- 2 1/2 inches
- 2 inches
- 1/2 inch
Securing devices must restrain the container from moving more than:
- 1.27 cm (1/2 in) forward.
- 1.27 cm (1/2 in) rearward.
- 1.27 cm (1/2 in) to the right.
- 1.27 cm (1/2 in) to the left.
- 2.54 cm (1 in) vertically.
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.
- 90 degrees.
- Less than 45 degrees.
- It doesn't matter.
The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
When securing a single metal coil with eyes vertical:
- These are all requirements.
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
To prevent the coil from tipping forward, rearward, and sideways, arrange tiedowns to include the following:
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
When securing concrete bell pipe in multiple complete tiers, all of the following are true except:
- Bells of the upper tiers must all be on the opposite side of the vehicle from the bells of the tier below.
- Bells of the bottom tier must all be on the same side of the vehicle
- All of these apply.
- Stack the tiers in pyramid fashion.
More than one tier with complete tiers
Bells of the bottom tier must all be on the same side of the vehicle
Bells of the upper tiers must be are on the opposite side of the vehicle from the bells of the tier below.

- 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.
