CDL Practice Tests: Flatbed Cargo Securement
Choose A Section:
Go!While driving, the freight must not:
- 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.
- Prevent the exit of a person from the cab.
- 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.
As part of their pre-trip cargo securement inspection, drivers should:
- Make sure cargo is properly secured.
- Check for anything that will obscure their vision.
- Inform carrier of any inadequate packaging.
- All of these apply.
Driver inspection checklist:
Pre-Trip
- Make sure that cargo is properly distributed and adequately secured (in other words, according to the Standard).
- Make sure that all securement equipment and vehicle structures are in good working order and used consistent with their capability.
- Stow vehicle equipment.
- Make sure that nothing obscures front and side views or interferes with the ability to drive the vehicle or respond in an emergency.
-
Inform carrier if packaging is not adequate. For example:
- Banding is loose or not symmetrical on package.
- Banding attachment device(s) are inefficient.
- Wrapping is broken or ineffective.
- Pallets are broken.
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.
What is the minimum Working Load Limit for the entire securement system?
- 80% of cargo weight.
- 100% of cargo weight.
- 50% of cargo weight.
- 20% 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.
Requirements for securing two stacks of shortwood loaded side-by-side include:
- At least one tiedown is used lengthwise across each stack.
- All of these are required.
- There is no space between the stacks of logs.
- The highest log is no more than 8 ft above the deck.
Additional requirements securement for two stacks side-by-side
In addition to the requirements for shortwood loaded crosswise, load two stacks side-by-side so that:
- There is no space between the stacks of logs.
- The outside of each stack is raised at least 2.5 cm (1 in) within 10 cm (4 in) of the end of the logs or from the side of the vehicle.
- The highest log is no more than 2.44 m (8 ft) above the deck.
- At least one tiedown is used lengthwise across each stack.
Which of the following is not a requirement of wood used as blocking or bracing?
- It should be properly seasoned.
- Hardwood is recommended.
- It should be free of decay and structural defects.
- It should be painted.
If wood is used:
- Hardwood is recommended.
- It should be properly seasoned.
- It should be free from rot or decay, knots, knotholes, and splits.
When loading bell pipe on one tier, all of the following apply except:
- If possible, the ends of consecutive pipe must be staggered within the allowable width.
- Load bell pipe on one tier so that the bells alternate on opposite sides of the vehicle.
- If the ends cannot be staggered, they must be aligned.
- Load bell pipe on one tier so that the bells all lie on one side of the vehicle.
One tier
Load bell pipe on one tier so that the bells alternate on opposite sides of the vehicle.
If possible, the ends of consecutive pipe must be staggered within the allowable width.
If the ends cannot be staggered, they must be aligned.
When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
- Rearward
- It doesn't matter
- Straight up and down
- Forward
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.

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

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.
