What types of freight need to be secured properly?
- All freight should always be properly secured while driving.
- Intermodal containers.
- Equipment used for vehicle operation.
- Hazardous materials.
-
Any cargo and dangerous goods/hazardous materials, including:
- All general freight.
- All equipment carried for vehicle operation.
- Intermodal containers and their contents.
- Some specific commodities have additional or different securement requirements (see later sections of this Handbook).
- Additional requirements under separate regulations may also apply for transportation of certain types of dangerous goods or hazardous materials.
Cargo
When calculating directional forces, 'g' is expressed as:
- 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.
- 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.
- 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.
- The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.

All of the following are requirements for dividing vehicles over 33ft except:
- Each tiedown must be fastened below the logs on each side of the center stake.
- Vehicle must be equipped with center stakes or comparable devices.
- Vehicle must be divided by center stakes into sections of staggered length.
- Each tiedown must secure the highest log on each side of the center stake.
Requirements for dividing vehicles over 10m (33 ft)
Vehicles over 10 m (33 ft) must be equipped with center stakes, or comparable devices, to divide it into sections of equal length.
Each tiedown must:
- Secure the highest log on each side of the center stake.
- Be fastened below these logs.

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

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.
