CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!When banding paper rolls with eyes vertical, you should:
- Spread rolls apart from each other.
- Apply bands loosely.
- Secure bands with tape, hangers, or other means.
- All of these are necessary.
Banding
If paper rolls are banded together:
- Place rolls tightly against each other to form a stable group.
- Apply bands tightly.
- Secure bands with tape, hangers, or other means so that the bands cannot fall off the rolls or slide down to the deck.
Methods to keep a cradle from sliding include:
- Nailed wood blocking or cleats.
- Placing a tiedown around the front of the cradle.
- These can all be used.
- Friction mats under the cradle.
Requirements for securing a single coil
Prevent the coil from rolling by supporting it:
- Timbers, chocks, or wedges held in place by coil bunks or similar devices to prevent them from coming loose.
- A cradle (for example, two hardwood timbers and two coil bunks) that is restrained from sliding by:
- Friction mats under the cradle.
- Nailed wood blocking or cleats.
- Placing a tiedown around the front of the cradle.
- The support must:
- Support the coil just above the deck.
- Not become unintentionally unfastened or loose in transit.
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 waterproof sheet used to cover cargo.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
Tarp:
A waterproof sheet used to cover cargo.
Securing heavy vehicles or equipment with crawler tracks or wheel requires a minimum of how many tiedowns?
- 2
- It depends on the weight of the load
- 6
- 4
Special Circumstances: Securing Heavy Vehicles, Equipment, or Machinery with Crawler Tracks or Wheels
Tiedown requirements
- Restrain cargo using a minimum of four tiedowns, each having a WLL of at least 2,268 kg (5,000 lb.).
- Prevents cargo movement in the side-to-side, forward, rearward, and vertical directions.
-
Attach tiedowns:
- Either at the front and rear of the vehicle.
- Or at the mounting points on the vehicle designed for that purpose.
The narrowest end of a boulder should be pointed:
- Towards the sky.
- Towards the front of the vehicle.
- It doesn't matter.
- Towards the rear of the vehicle.
If a boulder is tapered, point the narrowest end towards the front of the vehicle.
What is the maximum weight that can be secured by a tiedown with a marked WLL of 5,000 lbs?
- 2,500 lbs
- 10,000 lbs
- 5,000 lbs
- 6,000 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.
A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces is:
- Void filler.
- A friction mat.
- A cleat.
- A chock.
Friction mat:
A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.
The load carrying area of a truck, trailer, or intermodal container is referred to as the:
- Bulkhead
- Headboard
- Well
- Deck
Deck:
The load carrying area of a truck, trailer, or intermodal container.
When securing concrete pipe with a diameter up to 45 inches loaded crosswise as a group,lengthwise tiedowns should be either one 1/2 in chain or wire rope, or:
- One 3/8 inch chain or wire rope.
- Two 3/8 inch chains or wire ropes.
- Two 1/4 inch chains or wire ropes.
- Two nylon straps with aggregate WLL of 50% the weight of the load.
As a group
Place lengthwise tiedowns over the group of pipes:
Either one 13 mm (1/2 in) chain or wire rope,
Or two 10 mm (3/8 in) diameter chain or wire rope
When securing paper rolls with eyes vertical in a sided vehicle all of the following are acceptable except:
- Placing the rolls against each other.
- Placing rolls against the front and walls of the vehicle.
- Placing rolls against the doors.
- Placing the rolls against other cargo.
- Place paper rolls together in a group so that the structure of the group can be maintained.
- Place paper rolls against:
- The front and walls of the vehicle
- Each other
- Other cargo

- 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

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.
