CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!What is the minimum securement requirement for paper rolls with eyes vertical with a width between 1.25 and 1.76 its diameter?
- All of these are required.
- Friction mats alone.
- Tiedowns.
- Banding them together.
Situation #4
- A paper roll or the forwardmost roll(s) in a group of paper rolls is not prevented from tipping or falling forward by vehicle structure or other cargo.
- Paper roll width is more than 1.25 times and less than 1.76 times its diameter.
- Only friction mats are used for forward securement.
Solution #4:
The friction mat alone is adequate. The friction mat allows the roll to slide on the floor without tripping the roll.
When securing flattened or crushed cars on a vehicle with containment on 2 sides, how many tiedowns, at minimum, are required?
- 1
- 3
- 4
- 2
Option 3:
Has containment walls on two sides that:
- Extend to the full height of the load.
- Block against cargo movement in the forward and rearward.
Secures each stack of vehicles with a minimum of three tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
When banding paper rolls with eyes vertical, you should:
- Apply bands loosely.
- Spread rolls apart from each other.
- 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.
Which of these are requirements for securement systems?
- These all qualify as requirements.
- Components should be in proper working order.
- There should be no knots in the tiedowns.
- If a tiedown would be subject to cutting or abrasion, edge protection should be used.
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.

Vehicles
In terms of cargo securement, what is a 'well'?
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
- A female housing fixed to the side or ends of a vehicle to receive a stake or peg, and may also be used as an anchor point.
- 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.
Well:
The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
Methods to keep a cradle from sliding include:
- Friction mats under the cradle.
- Placing a tiedown around the front of the cradle.
- These can all be used.
- Nailed wood blocking or cleats.
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.
How much force is the securement system required to withstand in terms of cargo weight?
- 80% forward, 50% rearward, 80% sideways, 20% upwards.
- 50% forward, 20% rearward, 50% sideways, 20% upwards.
- 80% forward, 50% rearward, 50% sideways, 20% upwards.
- 50% forward, 50% rearward, 50% sideways, 80% 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%)
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.
What is the minimum weight of a load of metal coils that requires specific securement practices?
- 2,268 lbs
- It depends on the size of the coils.
- 50,000 lbs
- 5,000 lbs
Size of coil
All metal coil shipments that, individually or together, weigh 2,268 kg (5,000 lb.) or more must be secured according to the specific requirements in this section.
Exception: Metal coils that weigh less than 2,268 kg (5,000 lb.) may be secured according to general securement requirements.

- 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

- 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.
