CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!When securing building materials, spacer requirements include all of the following except:
- The length of spacers must provide support to all pieces in the bottom row of the bundle.
- If spacers are comprised of layers of material, the layers must be unitized or fastened together to ensure that the spacer performs as a single piece of material.
- Spacers must provide good interlayer friction.
- The height of each spacer must be equal or greater than the width.

To secure a cubic-shaped boulder, how many tiedowns are required, at minimum?
- 1
- 5
- 2
- 3
Special Circumstances: Securing a Cubic-Shaped Boulder
The securement of a cubic-shaped boulder must meet these requirements in addition to the other large boulder requirements in Section 13.
Secure each boulder individually with at least two chain tiedowns placed side-to-side across the vehicle.
Place tiedowns as closely as possible to the hardwood blocking used to support the boulder.
How many knots are acceptable in a properly working tiedown?
- 0
- 2
- 3
- 1
All components of a tiedown must be in proper working order.
- No knots or obvious damage
- No distress
- No weakened parts
- No weakened sections
When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
- 90 degrees.
- Between 45 and 60 degrees.
- Less than 45 degrees.
- It doesn't matter.
The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
A tiedown is defined as:
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- 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).
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).
When securing a single metal coil with eyes vertical:
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- 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 over eye of coil from side-to-side.
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.
What is the minimum Working Load Limit for the entire securement system?
- 50% of cargo weight.
- 100% of cargo weight.
- 20% of cargo weight.
- 80% of cargo weight.
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.
All of the following are requirements for transporting coils with eyes crosswise except:
- Attach one tiedown forward
- These are all requirements
- Attach one tiedown rearward
- Prevent the coil from rolling
There are three requirements for coils transported with eyes crosswise:
Prevent the coil from rolling
Attach one tiedown forward.
Attach one tiedown rearward.
When securing concrete pipe with a diameter of more than 45 inches loaded crosswise, how many tiedowns are required through each pipe at minimum?
- 1
- It depends on the weight of the pipe.
- 2
- 3
Requirements for securing the pipe
Secure each pipe with tiedowns through the pipe.
Run at least one tiedown through each pipe in the front half of the load. This includes the middle one if there are an odd number. The tiedown must run rearward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable.
Run at least one tiedown through each pipe in the rear half of the load. The tiedown must run forward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable. This holds each pipe firmly in contact with adjacent pipe.
Which of the following is not a method of securing side-by-side cargo?
- Make sure it is leaning forward.
- Place them in direct contact with each other.
- Use some kind of blocking to prevent shifting.
- Fill the empty space between with other cargo.
For articles of cargo placed beside each other and secured by side-to-side tiedowns:
Either place them in direct contact with each other,
Or prevent them from shifting towards each other in transit by using blocking or filling the space with other cargo.

- Wire rope
- Manila rope
- Synthetic rope
- Steel strapping
- Clamps and latches

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.
