Go!Which of the following are not covered by the specific log securement requirements?
- Loads of no more than four processed logs.
- None of these are covered by the specific log requirements
- Logs unitized by banding or other comparable means.
- Firewood, stumps, debris, other short logs, and longer 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.]
All of these are requirements for securing longwood lengthwise except:
- Each end of the log should extend at least 3 inches beyond the stakes.
- Each outside log should bear against at least two stakes, one near each end of the log.
- Must be cradled in two or more bunks or contained by stakes.
- Secure each log with at least two tiedowns if shorter logs are carried on top of the stack.
Requirements for securing longwood loaded lengthwise
- Longwood must be cradled in two or more bunks or contained by stakes.
- Each outside log should bear against at least two stakes, one near each end of the log.
- Each end of the log should extend at least 0.15 m (6 in) beyond the stakes.
- If shorter logs are carried on top of the stack, secure each log with at least two tiedowns.

- 6,000 lbs
- 2,500 lbs
- 10,000 lbs
- 5,000 lbs
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.
When using tiedowns for securing cargo, what is the general rule regarding cargo length.
- 1 tiedown for every 15 ft, or part thereof.
- 2 tiedowns for every 10 ft, or part thereof.
- 1 tiedown for every 10 ft, or part thereof.
- 1 tiedown for every 5 ft, or part thereof.
When cargo is prevented from forward movement (for example, by the headboard, bulkhead, other cargo, or tiedown), secure the cargo according to the following requirements:
All Cargo:
1 tiedown for every 10 ft, or part thereof.
What is the maximum angle recommended for tiedowns securing cement pipe loaded crosswise, relative to the deck?
- It doesn't matter
- 45-90 degrees
- 180 degrees
- 45 degrees
If the first pipe of a group in the top tier is not at the front of the tier beneath:
Attach an additional tiedown that runs rearward at an angle not more than 45 to the horizontal when viewed from the side of the vehicle, whenever practical.
Pass tiedown either through the front pipe of the upper tier or outside the front pipe and over both longitudinal tiedowns.
Cargo is contained when:
- It is packed in a square box.
- It is loaded on the end of the truck.
- 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 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.
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.
When securing a single metal coil with eyes vertical:
- Attach at least one tiedown over eye of coil from side-to-side.
- 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.
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.
Requirements for securing a non-cubic shaped boulder with a stable base include all of the following except:
- Attach chains together at the intersection
- Pass the tiedowns over the center of the boulder
- Wrap chains around the circumference of the boulder.
- Secure each boulder individually with at least two chain tiedowns forming an X pattern over the boulder.
Secure each boulder individually with at least two chain tiedowns forming an X pattern over the boulder.
Pass the tiedowns over the center of the boulder and attach them to each other at the intersection by a shackle or other connecting device.
When securing heavy vehicles, what is the minimum WLL of each tiedown?
- 50% of the weight of the cargo
- 5,000 lbs
- 10,000 lbs
- 2,268 lbs
- Restrain cargo using a minimum of four tiedowns, each having a WLL of at least 2,268 kg (5,000 lb.).
When securing metal coils in a sided vehicle without anchor points:
- Use locking and bracing
- Use friction mats
- Follow general cargo securement requirements
- All of these apply
Securing Coils Transported in a Sided Vehicle or Intermodal Container without Anchor Points
To prevent metal coils from moving horizontally and/or tipping:
Follow general cargo securement requirements
Secure the coils using:
- Blocking and bracing
- Friction mats
- A combination of these.
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.
