Flatbed securement and capability checks

securement is 49 cfr 393 subpart i

49 CFR 393 Subpart I sets tiedown working-load limits, device rules, and commodity-specific requirements. "We do flatbed" is not compliance. The regulation names logs, dressed lumber, metal coils, paper rolls, concrete pipe, automobiles, heavy vehicles, and other articles.

Tiedowns must meet the working-load-limit math for the cargo weight. Edge protection, dunnage, and blocking are part of the same subpart. A strap count the driver cannot explain is a stop for coils. It may be enough for a palletized, low-center load. Ask about this commodity.

Working-load limit is marked on the device or taken from the manufacturer tables the rule points to. "We always use four chains" is not math. Weight of the article plus how it sits on the deck changes the count. If they cannot talk WLL, they are not talking Subpart I.

Roadside inspectors write securement violations against the carrier and the driver. Your shipper still has a load on the ground if the coil is in the ditch. Vetting includes whether this driver can describe the plan.

commodity-specific rules are not optional

Metal coils have their own section. Concrete pipe, automobiles, and intermodal containers do too. If the driver cannot describe coil chocks, eye orientation, or how they keep a coil from rolling, do not send coils.

Ask whether they have hauled this commodity in the last 90 days. Recency is not in FMCSA. It is an operational fact. A fleet that last ran lumber in 2022 is not automatically a coil carrier today.

Census cargo codes such as metal sheets/coils/rolls, logs/poles/beams/lumber, building materials, and machinery are hints. They are not a securement certificate. Confirm the plan for the article on this bill of lading.

ask chains, grade, and tarps

Ask how many chains, what grade, how many straps, and whether tarps are required. Grade and working-load limit are how Subpart I is applied in the yard. "Plenty of chains" is not an answer.

Tarps, steel tarps versus lumber tarps, and whether the product must stay dry are shipper requirements on top of securement. Put tarp type on the rate con if the freight cannot take weather.

If they will not talk equipment until they have a rate, that is a sales tactic. You can still refuse to send a coil until they name the gear. A fast cover with no securement plan is how claims start.

trailer type has to match the freight

Flat, step-deck, lowboy, RGN, and hotshot are different trailers. A 48-foot flat does not take every machine a shipper wants to roll. Deck height and ramp capacity are operational facts. FMCSA will not list them.

Census power-unit count does not tell you they have a step-deck today. Ask what trailer will be at the shipper and whose name is on the doors. Equipment that far exceeds a one-truck census fleet is a reason to ask whose trailer it is.

Over-dimensional and permit loads add state permits. Those are not FMCSA authority. They still belong in the conversation after the federal file is clean. Do not skip L&I because the load needs a banner.

cargo limit is not bi&pd

Public liability under 49 CFR 387.9 is not cargo. A wrecked transformer is a cargo claim. A wrecked passenger car next to the transformer is a liability claim. Record both lines.

Used machinery, steel, and high-value equipment are common cargo exclusions or sublimits. Read the certificate. Load value must sit under the cargo limit after exclusions. If it does not, you need a different policy or a different carrier.

Named insured must be the motor carrier on the dispatch. A certificate for a related LLC is a stop. Producer callback is how you confirm the paper is real when the load value is high.

authority and identity still come first

A skilled flatbed operator with inactive authority is not coverable. Run L&I. Match legal name, MC, and DOT. Call the census phone. Then talk chains.

Double-broker patterns show up on equipment lanes because specialized trailers are scarce. If the pickup number comes from a third company after you booked an MC, stop. Confirm the driver with the office on the FMCSA record.

Rate con equipment block should match what you were told: trailer type, tarp, and commodity. A revised rate con that swaps the MC after hours needs a new check, not a hope that the same trailer will still show.

inspections can hint, they cannot certify the next load

Vehicle maintenance and securement-related violations on SMS or the inspection file are questions. A pattern of cargo-securement citations is a conversation. A clean file is not a tiedown plan for this coil.

Small fleets have noisy samples. One OOS on a two-truck carrier is not the same as a pattern on a 200-truck fleet. Use inspections as questions: "why did the last inspection light on securement?"

Do not tell a shipper a percentile as if it were a securement rating. Put the last inspection date in the file if you used it. Put the driver's description of the tiedown plan next to it.

permits and banners are not operating authority

Over-dimensional and overweight permits are state documents. They do not grant interstate operating authority. They do not replace a BMC-91. Run L&I first. Then talk permits.

Escort cars, banner size, and travel-time windows are operational. The motor carrier on the rate con is still the carrier who must hold the federal grant. A permit office in another company's name is a reason to ask whose load this is.

If a third party is "handling permits" and also wants the rate con in their name, you are in dispatch-service or re-broker territory. Keep the MC as the FMCSA legal entity. Keep payment on that entity or its factor.

Machinery ramps, chain binders, and coil racks are gear. Ask if that gear is on the trailer that will arrive. A photo of a different truck's deck is not the deck at your shipper.

desk checklist

• L&I authority and required BI&PD cleared before equipment talk.
• Trailer type matches the freight (flat, step, RGN, or other named type).
• Driver or dispatcher can describe the Subpart I plan for this commodity.
• Chains or straps, grade or WLL, and tarp requirement stated.
• Cargo limit covers product value after exclusions; named insured matches the MC.
• Census cargo codes treated as hints, not as a coil or lumber registry.
• Identity: census phone and rate con name match the entity that will dispatch.

what belongs in the load file

• Dated L&I screen and QCMobile or SAFER snapshot.
• Note of trailer type, chain/strap count and grade or WLL, tarp yes/no.
• Cargo certificate showing named insured, limit, and commodity exclusions.
• Rate con commodity and equipment block matching that note.

fail closed

• Driver cannot describe coil (or other commodity-specific) securement for that article.
• Trailer type on the call does not match what the shipper can load.
• Cargo policy excludes this commodity or sits under load value.
• MC on a revised rate con was not re-checked.
