Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
A cleat is a short piece of wood used:
- To reinforce blocking.
- To make pallets.

Cleat:
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
A chock is generally used to secure:
- Slippery articles.
- Over-sized loads.
- Tall cargo.
- Round articles.
Chock:
A tapered or wedge-shaped piece used to secure round articles against rolling.

- 45 degrees.
- 30 degrees.
- 180 degrees.
- 90 degrees.
At least one direct tiedown against the front of the row of coils, restraining against forward motion, and if practicable, making an angle 45 degrees or less with the floor.
At least one direct tiedown against the rear of the row of coils, restraining against rearward motion, and if practicable, making an angle 45 degrees or less with the floor.
A dunnage bag is:
- 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.
- A waterproof sheet used to cover cargo.
- Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
- An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
Dunnage bag:
An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
About The New York State Coil Exam
You must have a New York State coil endorsement if you want to haul metal coils in New York.
Performance Criteria for Securement Systems:
Part I: Cargo Securement Performance Criteria
The standard provides the minimum amount of force that cargo should be expected to withstand, in each direction, as shown below.
These minimum force requirements, called the “performance criteria”, were determined after extensive testing. The securement system MUST be capable of resisting these forces, as shown below.
- The forward force (80% of the cargo weight) represents braking while driving straight ahead.
- The rearward force (50% of the cargo weight) represents vehicle acceleration or braking in reverse.
- The side-to-side or lateral force (50% of the cargo weight) represents traveling on a curve, ramp or changing lanes.
- The vertical force (20% of the cargo weight)) represents cargo vibration during transport. This requirement is satisfied when the cargo is "Fully Contained"
The performance criteria may also be expressed in terms of acceleration, which is shown at right (“g” is the term used for gravity, and represents acceleration or deceleration).
- 0.8 g deceleration in the forward direction.
- 0.5 g deceleration in the rearward direction.
- 0.5 g acceleration in a side-to-side or lateral direction.
- 0.2 g vertical acceleration.
EXAMPLE: If a steel coil weighs 10,000 lbs., the load securement must provide 8,000 lbs. of securement to prevent movement in the forward direction, which is expressed as 80% of the cargo weight (or 0.8 g).
PART II - Performance Criteria for Components of a Securement System
Each component of the cargo securement system should not exceed its Working Load Limit (WLL), when at maximum force. The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system during normal service; it is usually assigned by the manufacturer of the component.
Each force in the performance criteria is to be applied separately to the securement system to determine if it is compliant.
Cargo Securement Terms That Truck Drivers Should Know:
-
Working Load Limit (WLL):
The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
-
g:
The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.
-
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.
-
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).
Vehicle Structure and Anchor Points
The vehicle must be strong enough to resist the forces in the performance criteria (Section 1). The vehicle must be appropriate for the cargo it is to transport, or it must be adapted to be suitable by using fittings, fixtures, dunnage, cribbing or other means.
Cargo Securement Responsibility
According to federal and state regulations, the carrier and driver are responsible for ensuring that the vehicles, anchor points and other securement components are in good working order, with no obvious signs of damage. The driver is also required to conduct a pre-trip inspection by other operating regulations.
Roadside inspections are conducted in accordance with federal, state and provincial laws. If securement equipment fails inspection, it is likely that the vehicle may be placed out-of-service, and the motor carrier and/or the driver may be fined.
