A stack of shortwood loaded lengthwise can be secured with one tiedown if:
- All logs in the stack are less than 10 ft long.
- They are blocked in the back by the vehicle's end structure or another stack of logs.
- They are blocked in the front by a headboard or another stack of logs.
- All of these apply.
One tiedown
A stack can be secured with one tiedown if all logs in the stack less than 3.04 m (10 ft) are:
- Blocked in the front by a headboard strong enough to restrain the load or by another stack of logs.
- Blocked in the rear by the vehicle's end structure or another stack of logs.
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
Within the requirements for concrete pipe, which of these requires specific securement methods?
- Concrete pipe loaded cross-wise on a flatbed trailer.
- Concrete pipe loaded in a sided vehicle or container.
- Concrete pipe eyes vertical and concrete pipe loaded lengthwise.
- Concrete pipe that is grouped together into a single rigid article and may not roll.
What is exempt from these specific requirements?
Follow general cargo securement requirements (Section 2) when transporting the following pipe:
- Concrete pipe that is grouped together into a single rigid article and may not roll.
- Concrete pipe loaded in a sided vehicle or container.
- Concrete pipe eyes vertical and concrete pipe loaded lengthwise.
What is covered under these specific requirements?
Any concrete pipe loaded crosswise on a platform trailer or vehicle that is not exempt.
'Blocking' is defined as:
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
What types of freight need to be secured properly?
- All freight should always be properly secured while driving.
- Intermodal containers.
- Equipment used for vehicle operation.
- Hazardous materials.
-
Any cargo and dangerous goods/hazardous materials, including:
- All general freight.
- All equipment carried for vehicle operation.
- Intermodal containers and their contents.
- Some specific commodities have additional or different securement requirements (see later sections of this Handbook).
- Additional requirements under separate regulations may also apply for transportation of certain types of dangerous goods or hazardous materials.

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.
