To secure a cubic-shaped boulder, how many tiedowns are required, at minimum?
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.
When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
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.
In what circumstance can shortwood be treated as longwood?
Some stacks may be made up of both shortwood and longwood. Any stack that includes shortwood must follow the shortwood securement requirements.
Exception: If shortwood is embedded in load of longwood, it can be treated as longwood.
How much force is the securement system required to withstand in terms of cargo weight?
All elements of the vehicle structure and anchor points must be strong enough to withstand the forces described on page 7.
When using tiedowns to secure boulders, all of the following are requirements except:
Use only chain to secure large boulders.
Should be located in valleys or notches across the top of the boulder
Must be arranged to prevent sliding across the rock surface.
What is the minimum number of tiedowns to use on a load 4ft 7in long, and weighing 1,237 lbs?
Minimum number of tiedowns: 1
Minimum number of tiedowns: 2
Minimum number of tiedowns: 2
An anchor point is defined as:
Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
When using tiedowns for securing cargo, what is the general rule regarding cargo length.
When cargo is prevented from forward movement (for example, by the headboard, bulkhead, other cargo, or tiedown), secure the cargo according to the following requirements:
1 tiedown for every 10 ft, or part thereof.
While driving, the freight must not:
All of these are requirements for securing longwood lengthwise except:

Studying the flatbed cargo securement CDL manual is not a requirement for getting your CDL permit or license. It is required knowledge for flatbed drivers.
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.
