What is a rub rail?
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- 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 platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
Rub Rail:
A rail along the side of a vehicle that protects the side of the vehicle from impacts.

- 3
- 6
As a group
Place lengthwise tiedowns over the group of pipes:
Either one 13 mm (1/2 in) chain or wire rope,
Or two 10 mm (3/8 in) diameter chain or wire rope
Place one crosswise tiedown for every 3.0 m (10 ft) of load length.
Either attach the side-to-side tiedown through a pipe
Or pass the tiedown over both front-to-back tiedowns between two pipes on the top tier.
What is the minimum WLL of each tiedown used to secure crushed or flattened vehicles?
- 10,000 lbs
- It depends on the vehicle
- 5,000 lbs
- 2,268 lbs
Option 2:
Has containment walls on three sides that:
- Extend to the full height of the load
- Block against cargo movement in the forward, rearward, and one sideways direction.
Secures each stack of vehicles with a minimum of two tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Option 3:
Has containment walls on two sides that:
- Extend to the full height of the load.
- Block against cargo movement in the forward and rearward.
Secures each stack of vehicles with a minimum of three tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Option 4:
Has a minimum of four tiedowns per vehicle stack with each tiedown having a minimum WLL of 2,268 kg (5,000 lb.).
The maximum distance from the rear allowed for attaching mechanisms used to secure roll-on/roll-off containers is:
- 2 feet
- It doesn't matter.
- 6 1/2 feet
- 3 feet
Attach mechanisms used to secure the rear end of a roll-on/roll-off or hook lift container no more than two meters (6.5 feet) from the rear of the container.
About The Flatbed Cargo Securement CDL Manual
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:
- What is the minimum Working Load Limit of a tiedown used to secure logs?
- What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
- When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
- What is a cab shield?
- When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
- What is a dunnage bag?
- Who is responsible for inspecting securing devices and cargo within the first 50 miles?
- How many tiedowns are required on a stack of shortwood loaded crosswise?
- What is the minimum working load limit of each tiedown used to secure crushed or flattened vehicles?
- Define 'bolster'
- What is a hook-lift container?
- When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
What is a securing device?
Any device specifically manufactured to attach or secure cargo to a vehicle or trailer:
- Synthetic Webbing
- Chain
- Wire rope
- Manila rope
- Synthetic rope
- Steel strapping
- Clamps and latches
- Blocking
- Front-end structure
- Grab hooks
- Binders
- Shackles
- Winches
- Stake pockets
- D-rings
- Webbing ratchet
- Bracing
- Friction mat
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.
