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 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).
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
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).
Option #1 for securing coils transported with eyes lengthwise includes:
- Attaching at least one tiedown diagonally from the left side of the vehicle, through the eye, to the right side of the vehicle
- Using blocking or friction mats to prevent forward movement.
- It should include all of these things

Tiedowns, Single Coil Option #1
Attach at least one tiedown diagonally from the left side of the vehicle, through the eye, to the right side of the vehicle. If possible, the angle between the tiedown and the deck should be less than 45, when viewed from the side of the vehicle.
Attach at least one tiedown diagonally from the right side of the vehicle, through the eye, to the left side of the vehicle. If possible, the angle between the tiedown and the deck should be less than 45, when viewed from the side of the vehicle.
Attach at least one tiedown side-to-side over the top of the coil.
Use blocking or friction mats to prevent forward movement.
A stack of shortwood loaded lengthwise can be secured with one tiedown if:
- They are blocked in the front by a headboard or another stack of logs.
- All logs in the stack are less than 10 ft long.
- All of these apply.
- They are blocked in the back by the vehicle's end structure or another stack of logs.
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.
To prevent rolling, how many points of contact are required, at minimum, for a boulder resting on a rounded or partially rounded side?
- 2
- 3
- 5
- 4
Requirements
If the flattest side of the boulder is rounded or partially rounded, place the boulder in a crib made of hardwood fixed to deck of vehicle.
Boulder should rest on both deck and timber, with at least 3 well-separated points of contact that prevent rolling in any direction.
When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
- Rearward
- Straight up and down.
- It doesn't matter.
- 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 the maximum angle recommended for tiedowns securing cement pipe loaded crosswise, relative to the deck?
- It doesn't matter
- 180 degrees
- 45-90 degrees
- 45 degrees
If the first pipe of a group in the top tier is not at the front of the tier beneath:
Attach an additional tiedown that runs rearward at an angle not more than 45 to the horizontal when viewed from the side of the vehicle, whenever practical.
Pass tiedown either through the front pipe of the upper tier or outside the front pipe and over both longitudinal tiedowns.
When securing paper rolls with friction mats as a primary method:
- All of these answers.
- Make sure friction mats are completely covered by the roll.
- The friction mat should stick out from underneath the roll in the direction it is providing securement.
- The friction mat should stick out from underneath the roll in the opposite direction for which it is providing securement.
Requirements for friction mats
If a friction mat is used to provide the principal securement for a paper roll, insert the friction mat so that it sticks out from beneath the footprint of the roll in the direction in which it is providing securement.
Load securement for cargo weighing 29,650 lbs must be able to withstand upward force of how many lbs?
- 5,930 lbs
- 14,825 lbs
- 30,000 lbs
- 29,650 lbs
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%)
As part of their pre-trip cargo securement inspection, drivers should:
- Check for anything that will obscure their vision.
- Make sure cargo is properly secured.
- 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.

- 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.
