- These are all requirements.
- 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:

When securing a paper roll with a width that is more than twice its diameter, which of the following is not an acceptable method of securement to prevent tipping?
- Band the roll to other rolls.
- Use rear doors to brace it.
- Use tiedowns.
- Brace it.
Situation #1:
- Paper roll is not prevented from tipping by the vehicle structure or other cargo.
- Paper roll width is more than 2 times its diameter.
Solution #1:
- Either band the roll to other rolls.
- Or brace it.
- Or use tiedowns.
When loading and securing a boulder, it should be:
- Supported on at least 2 pieces of 4in x 4in hardwood blocking, extending the full width of the boulder.
- Placed on symmetrical hardwood blocking that extends 3/4 of the length of the boulder.
- Placed on the vehicle with its largest or flattest side down.
- All of these are requirements.
Requirements
Place each boulder on the vehicle with its flattest and/or largest side down.
Support each boulder on at least two pieces of hardwood blocking (at least 10 cm x 10 cm (4 x 4 in) that extend the full width of the boulder.
Place hardwood blocking pieces as symmetrically as possible under the boulder so they support at least 3/4 of the length of the boulder.
If you were instructed to 'tarp' a load, what would you be using?
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself.
- A platform or tray on which cargo is placed so that it can be handled as an article.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.

Tarp:
A waterproof sheet used to cover cargo.
When securing heavy vehicles, what is the minimum WLL of each tiedown?
- 2,268 lbs

- 50% of the weight of the cargo
- 10,000 lbs
- Restrain cargo using a minimum of four tiedowns, each having a WLL of at least 2,268 kg (5,000 lb.).
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 building materials, how many knots are acceptable in the tiedown(s)?
- 0
- 1
- 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.
What is bell pipe concrete?
- Concrete used to make bell pipe.
- Pipe used to make concrete bells.
- Pipe whose flanged end is of larger diameter than its barrel.
- Pipe whose flanged end is of smaller diameter than its barrel.
Bell Pipe Concrete:
Pipe whose flanged end is of larger diameter than its barrel.
As part of their pre-trip cargo securement inspection, drivers should:
- Inform carrier of any inadequate packaging.
- Check for anything that will obscure their vision.
- Make sure cargo is properly secured.
- All of these apply.
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.
How much force is the securement system required to withstand in terms of cargo weight?
- 50% forward, 50% rearward, 50% sideways, 80% upwards.
- 80% forward, 50% rearward, 80% sideways, 20% upwards.
- 80% forward, 50% rearward, 50% sideways, 20% upwards.
- 50% forward, 20% rearward, 50% sideways, 20% upwards.
How strong must the vehicle structure and anchor points be?
All elements of the vehicle structure and anchor points must be strong enough to withstand the forces described on page 7.
- Forward force: 0.8 g (80%)
- Rearward force: 0.5.g (50%)
- Sideways force: 0.5 g (50%)
- Upward force: 0.2 g (20%)
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
- 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.
