Go!When loading paper rolls with eyes horizontal, which of the following is not a requirement for stacking a second layer:
- 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.
- The bottom layer must extend all the way to the front.
- Place second layer with eyes vertical.
- All the wells in the layer beneath must be filled
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.

The narrowest end of a boulder should be pointed:
- Towards the sky.

If a boulder is tapered, point the narrowest end towards the front of the vehicle.
When securing metal coils with eyes vertical, the angle between tiedown and deck, if possible, should be:
- 60 degrees
- Between 60 and 90 degrees
- Less than 45 degrees

- Attach at least one tiedown against front of row of coils to restrain against forward motion. If possible, angle between tiedown and deck should be less than 45, when viewed from the side of the vehicle.
- Attach at least one tiedown against rear of row of coils to restrain against rearward motion. If possible, angle between tiedown and deck should be less than 45, when viewed from the side of the vehicle.
- Attach at least one tiedown over top of each coil or side-by-side row of coils to restrain against vertical motion. Tiedowns going over top of coil(s) must be as close as possible to eye of coil.
- Arrange tiedowns, blocking, or bracing to prevent shifting or tipping in all directions.
If the cargo is fully contained in a sided vehicle, what is the minimum requirement for withstanding sideways force?
- 0.2g (20% of cargo weight)
- 0.7g (70% of cargo weight)
- 0.5g (50% of cargo weight)
- 0.8g (80% 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%)
The term 'edge protector' refers to:
- A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
- A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
Edge protector:
A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
Which of the following can be used as part of the cargo securement system?
- Blocking and bracing equipment.
- Vehicle structure.
- Securing devices.
- All of these are valid.
What is a securement system?
A securement system is a securement method that uses one or a combination of the following elements:
- Vehicle Structure.
- Securing Devices.
- Blocking and Bracing Equipment.
While driving, the freight must not:
- Prevent the exit of a person from the cab.
- Interfere with the free movement of the driver's arms or legs.
- All of these things should be avoided.
- Obscure the driver's view ahead, left, or right.
- Obscure the driver's view ahead or to the right or left sides (except for drivers of self-steer dollies).
- Interfere with the free movement of the driver's arms or legs.
- Prevent the driver's free and ready access to accessories required for emergencies. OR
- Prevent the free and ready exit of any person from the commercial motor vehicle's cab or driver's compartment.
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.
