Not all cargo plays by the same rules, and that is exactly where most securement violations start. A driver who knows the general tie-down count rules cold can still get cited hauling steel coils, because coils, logs, lumber, pipe, and heavy machinery each have their own dedicated section under FMCSA regulations that overrides the general standard entirely. A truck cargo securement inspection checklist only works if it accounts for what is actually on the trailer, not just how much it weighs.
General cargo securement rules under 49 CFR 393.100 set the baseline for tie-down count and working load limit, but FMCSA has adopted separate, more detailed rules for logs, dressed lumber, metal coils, paper rolls, concrete pipe, intermodal containers, and heavy machinery. When a commodity-specific rule applies, it overrides the general rule, not the other way around. An inspection checklist built around commodity type, not just weight, is what actually keeps a fleet out of the $18,000 fine range that FMCSA can impose for a single securement violation.
Why One Checklist Does Not Fit Every Load
The general rule is straightforward: articles under 5 feet and 500 pounds need one tie-down, articles 5 to 10 feet need two, and longer articles need one more for every additional 10 feet. But FMCSA specifically built out separate chapters for the commodities that cause the most disagreement between drivers and inspectors, because a coil of steel and a bundle of lumber fail in completely different ways.
When the Commodity Rule Wins
If a load fits a commodity-specific chapter, that chapter is the standard an inspector applies, not the general rule. A driver who secures a load of steel coils using only the general tie-down count table is not following an alternate acceptable method. They are violating the rule that actually governs that cargo.
| Commodity | Minimum Requirement | Special Note |
|---|---|---|
| Logs (unbanded) | At least 2 tie-downs per tier, rated bunks | Shorter logs may still need more depending on tier height |
| Dressed lumber | 2 tie-downs per stack, +2 per added stack layer | Belly straps required on stacked pallets |
| Metal coils (5,000+ lbs) | Blocking or bracing based on eye orientation | Eyes-vertical coils need blocking on both sides against tipping |
| Concrete pipe | Arrangement and blocking scaled to inside diameter | Bundled pipe with no roll tendency may use general rules instead |
| Heavy machinery (10,000+ lbs) | Minimum 4 tie-downs, 5,000 lb WLL each | Buckets, booms, and blades must be lowered and secured separately |
FleetRabbit's cargo securement module automatically routes drivers to the correct commodity-specific checklist, whether the load is dressed lumber, steel coils, or general freight. Sign up for a free trial to see it adapt to your fleet's exact freight mix.
Building an Inspection Program Around the Load, Not Just the Truck
Commodity-specific securement is only half the picture. When and how often a load gets checked matters just as much as how it was tied down at the dock.
Pre-Load Vetting Is a Dispatch Job
Before a load is even accepted, dispatch should confirm the commodity type, get an accurate weight, and verify the assigned driver has the correct tie-down inventory and prior experience for that specific commodity. A carrier should not book a coil load for a driver who has never secured coils, and should not assign a machinery move without confirming the fleet has the rated chain and binder inventory the job actually requires.
On-Route Recheck Intervals
Securement is not a one-time check at the dock. Federal rule requires a check within the first 50 miles of a trip, then again every 150 miles or three hours, whichever comes first, for the rest of the route. Some commodities, particularly higher-risk industrial materials, may call for more frequent checks under state rules or shipper contracts on top of the federal minimum.
What an Auditor Actually Verifies
An inspector who finds no evidence of a recent cargo check can issue a citation even if the load happens to still be properly secured at that exact moment. Documentation of the inspection, not just the physical condition of the tie-downs, is part of what gets verified during a roadside stop or a compliance review.
FleetRabbit logs every pre-load and on-route securement check with a timestamp and photo, so your fleet has proof of inspection, not just a memory of one. Book a demo to see the recheck workflow in action.
Frequently Asked Questions
Cargo securement compliance is not about memorizing one universal rule. It is about knowing which of eleven different FMCSA chapters actually governs the load on the trailer, and building your inspection habits around that answer. Match the checklist to the commodity, document every recheck, and roadside surprises become the exception instead of the norm. Sign up for FleetRabbit to put commodity-specific checklists on your drivers' phones, or book a demo to see it working across your fleet's actual freight mix.
FleetRabbit routes drivers to the correct commodity-specific securement checklist, logs every pre-load and on-route recheck, and builds an audit-ready compliance record automatically. Start free, no credit card required.
