What is a rub rail?
A rail along the side of a vehicle that protects the side of the vehicle from impacts.
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.
A crosswise load bearing structural component, particularly a part of a log bunk.
Within the requirements for concrete pipe, which of these requires specific securement methods?
Follow general cargo securement requirements (Section 2) when transporting the following pipe:
Any concrete pipe loaded crosswise on a platform trailer or vehicle that is not exempt.
A chock is defined as:
A tapered or wedge-shaped piece used to secure round articles against rolling.
What is the minimum WLL required of tiedowns securing loaded intermodal containers on non-chassis vehicles?
Secure each container to the vehicle by:
Secure the front and rear of the loaded container independently.
Secure the four corners using tiedowns that are attached to the loaded container.
The tiedowns must have an aggregate working load limit of at least 50% of the loaded weight of the loaded container.
Attach each chain, wire rope, or integral locking device to the container in a manner that prevents it from becoming unfastened while in transit.
What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
The rules in this section apply to shipments of paper rolls, which individually or together, weigh 2268 kg (5000 lb.) or more.
Note: Shipments of paper rolls that weigh less than 2268 kg (5000 lb.), and paper rolls that are unitized on a pallet may either be secured in accordance this section or with the general cargo securement requirements
When securing rows of coils, requirements include all of the following except:
Attach at least one tiedown over the top of each coil or side-by-side row, located near the front of the coil.
Attach at least one tiedown over the top of each coil or side-by-side row, located near the rear of the coil.
Use blocking or friction mats to prevent forward movement.
Securing heavy vehicles or equipment with crawler tracks or wheel requires a minimum of how many tiedowns?
When securing paper rolls with friction mats as a primary method:
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.

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.
