Weighs more than 5,000 kg (11,000 lb.) or has a volume greater than two cubic meters
Is transported on an open vehicle or in a vehicle whose sides are not designed and rated for the transportation of boulders.
Which of the following is not true of Working Load Limit (WLL)?
The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system during normal service.
The WLL is usually assigned by the component manufacturer.
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.

Some questions you should be able to answer for flatbed cargo securement:
Any device specifically manufactured to attach or secure cargo to a vehicle or trailer:
A combination of securing devices that forms an assembly that:
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.
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).
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.
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
Tiedowns can be used in two ways:
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.
