Cargo Securement: When a Load Isn’t Safe to Move

A load being on the trailer does not mean it is ready to move. Before pulling away, a carrier has to ask a more important question: Is this cargo actually secured for the road?

Cargo can shift during braking, turns, acceleration, lane changes, and other normal driving conditions. FMCSA requires cargo on commercial motor vehicles to be loaded and secured to prevent it from leaking, spilling, blowing, or falling from the vehicle and to prevent shifting that adversely affects vehicle stability or maneuverability.

Securement Is More Than Throwing a Strap Over the Freight

FMCSA’s general rule requires cargo to be firmly immobilized or secured using adequate vehicle structures, dunnage, dunnage bags, shoring bars, tiedowns, or an appropriate combination of securement methods.

Vehicle structures, systems, parts, and components used to secure cargo must also be in proper working condition and cannot have damage or weakness that adversely affects their performance.

That means straps, chains, anchor points, and other securement equipment should never be treated as an afterthought. A damaged securement device does not become acceptable because the delivery appointment is getting close.

Working Load Limit Matters

Under FMCSA’s general securement rules, the aggregate working load limit of the securement system used to prevent an article—or group of articles—from moving must generally be at least one-half the weight of the cargo being secured.

But that does not mean “half the cargo weight” is the only rule that matters. The securement system must also satisfy applicable requirements for the number and placement of tiedowns, proper use of securement devices, cargo characteristics, and any commodity-specific rules.

How Many Tiedowns Do You Need?

There is not one universal answer such as “every load needs four straps.” For articles that are not blocked or positioned to prevent forward movement, FMCSA’s general rules use the cargo’s length and weight to help determine the minimum number of tiedowns.

For example, under the general rule, an article 5 feet or shorter and 1,100 pounds or less generally requires at least one tiedown. Certain heavier or longer articles require additional tiedowns. For an article longer than 10 feet that is not blocked against forward movement, the general rule calls for two tiedowns for the first 10 feet and an additional tiedown for each additional 10 feet—or fraction thereof.

Those general calculations do not replace commodity-specific securement requirements when those requirements apply.

If It Can Roll, Treat It Like It Can Roll

FMCSA specifically addresses cargo that is likely to roll. Such cargo must be restrained using chocks, wedges, a cradle, or another equivalent method that prevents rolling. The method used to prevent rolling must itself be secured against unintentionally becoming loose while the vehicle is moving.

Looking at freight and thinking, “That looks heavy enough that it probably won’t move,” is not a securement method.

Some Cargo Has Its Own Rules

FMCSA has commodity-specific securement requirements for cargo including logs; dressed lumber and similar building products; metal coils; paper rolls; concrete pipe; intermodal containers; automobiles, light trucks, and vans; heavy vehicles, equipment, and machinery; flattened or crushed vehicles; roll-on/roll-off and hook-lift containers; and large boulders.

When applicable, those commodity-specific requirements can impose additional or more detailed requirements beyond the general rules.

For example, FMCSA’s specific metal-coil rules apply to one or more metal coils that individually or together weigh 5,000 pounds or more. Heavy vehicles, equipment, and machinery weighing 10,000 pounds or more individually also have specific securement requirements.

This is why Digital Queen Logistics will not tell a carrier, “Just use X number of chains and you’re good.” We need to know what you are hauling first.

Protect Your Tiedowns Too

Cargo itself can damage the equipment being used to secure it. FMCSA requires edge protection when a tiedown would be subject to abrasion or cutting where it contacts the cargo. The protection must resist abrasion, cutting, and crushing.

Tiedowns must also be attached and secured in a way that prevents them from becoming loose, unfastening, opening, or releasing while the vehicle is in transit.

So the question is not only, “Is there a strap there?” It is, “Is that strap being used correctly, and is the cargo going to damage it?”

Securement Is Not Always “Check It Once and Forget It”

Federal rules under §392.9 also impose cargo-inspection responsibilities on drivers in covered circumstances. FMCSA confirms that carriers must comply not only with the cargo-securement rules in Part 393, but also with §392.9.

Those rules can require cargo and securement devices to be checked during a trip, including an inspection within the first 50 miles and subsequent reexaminations when specified conditions are met. There are exceptions to certain inspection requirements—for example, some sealed loads or situations where the cargo is not accessible to the driver—so carriers should review the rule that applies to their operation rather than assuming every load is treated identically.

What If the Shipper Wants You to Move Anyway?

This is where safety and business pressure can collide. Maybe loading took too long. Maybe the appointment is tight. Maybe somebody says, “That’s how we always load it.”

None of those statements changes whether the cargo is properly secured. If something about the load appears unsafe or you do not understand how the commodity must be secured, stop and resolve the issue before moving the truck.

Document the concern. Communicate it. Get clarification when needed. And do not allow somebody else’s schedule to turn into your safety problem.

The DQ Cargo Securement Check

The Load Is Not Worth More Than the Truck—or the Driver

Freight can be rebooked. Appointments can be rescheduled. Difficult phone calls can be handled. But once an improperly secured load shifts, falls, rolls, or affects the stability of the truck, the consequences can become much more serious.

Professional carriers do not secure freight merely because an inspector might check it. They secure freight because that is what protects the driver, the equipment, the cargo, and everybody else sharing the road.
