What 393.126(c) means in plain language
When you transport a flattened or crushed vehicle—such as a junked car, crushed metal, or compacted refuse vehicle—it must be secured in a way that prevents it from shifting, falling, or becoming a hazard during transport. This code addresses the methods and equipment used to keep such cargo from moving during braking, acceleration, or sharp maneuvers.
The regulation requires that your cargo securement system be appropriate for the weight, shape, and condition of the load. A flattened or crushed vehicle may have irregular edges, unstable geometry, or sharp protrusions that demand extra attention. Loose or inadequate restraints—chains, straps, binders, or blocking—create risk of load shift, spill, or ejection onto the roadway.
If an inspector finds that your flattened or crushed vehicle cargo is not properly secured, they will cite this violation. It is not a minor paperwork issue; it is a vehicle safety defect that affects road safety.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.126(c) is rarely cited. All-time, we see only 19 citations for this violation, with zero citations in the last 12 months and zero in the last 90 days. This makes 393.126(c) ranked #1962 of 3,036 FMCSR codes by citation volume—one of the least frequently enforced codes in the database.
However, the enforcement picture changes dramatically when a citation is issued. Our data shows a 100.0% out-of-service rate for this violation. Every single citation (19 out of 19) resulted in the vehicle being placed out of service. This is substantially higher than the all-FMCSR average out-of-service rate of 31.4%, indicating that when inspectors find this defect, they view it as a serious safety hazard that requires immediate remedy.
The near-zero citation frequency over the past 90 days and 12 months suggests either that most carriers are complying with cargo securement standards for flattened vehicles, or that this specific scenario—transporting flattened or crushed vehicles with improper securement—is uncommon in the inspected population. Either way, if you are cited, you should treat it as a critical safety and compliance issue.
Who gets cited most
Our inspection database does not segment 393.126(c) citations by state in a way that identifies a clear top-three state distribution. The enforcement volume is too low (19 all-time citations) to establish reliable geographic patterns.
At the carrier level, our data shows citations distributed across a range of operations. Roehl Transport Inc, Tennessee Steel Haulers LLC, Sullivan Trucking of Auburn Inc, and several other carriers each have one citation on record. No single carrier dominates this violation, suggesting that improper securement of flattened vehicles occurs sporadically across different fleet sizes and operational models rather than clustering in one segment.
Among vehicle makes cited, our inspection records show Freightliner appearing in 7 citations for this violation, followed by Peterbilt, Wilson Trailers, and Kenworth with 3 citations each. This distribution reflects the prevalence of these makes in heavy-haul and specialty trucking, where flattened-vehicle transport is more common. If you operate one of these makes in specialty haul work, pay particular attention to cargo securement protocols.
How severe is this compared to similar codes
To contextualize 393.126(c), we can compare it to other vehicle maintenance and cargo securement codes in our database:
393.9(a) — Inoperable required lamps has 660,737 citations and a 15.4% out-of-service rate. This is cited far more frequently than 393.126(c), but when it is cited, it results in an OOS decision only 15% of the time.
396.3(a)(1) — Inspection/repair/maintenance (general) shows 236,919 citations with a 45.3% out-of-service rate. This code is roughly 12,000 times more common than 393.126(c), and it places vehicles out of service in 45% of cases—still well below the 100% OOS rate we see for flattened-vehicle securement.
393.78 — Windshield condition defective has accumulated 157,894 citations with only a 0.3% out-of-service rate, showing that most lighting and visibility defects are correctable without immediate roadside remedy.
The 100% out-of-service rate for 393.126(c) tells you that inspectors regard improper securement of flattened vehicles as immediately hazardous—more so than typical brake, lamp, or maintenance findings. You cannot defer this citation or negotiate a repair timeline.
How to avoid it
Based on the violation definition and the vehicle makes most frequently cited, here are concrete steps to avoid a 393.126(c) citation:
-
Inspect all contact points before loading. Before your flattened or crushed vehicle cargo is loaded onto your trailer, walk the entire load. Look for sharp edges, protruding metal, or unstable stacking. Ensure the cargo sits level and will not roll or shift.
-
Use appropriate securement hardware. Chains, binders, or straps must be rated for the weight and shape of the load. Do not assume that standard E-track or side rails are sufficient for an irregular, flattened load. Consult your carrier's securement manual or the manufacturer guidelines for specialty haul.
-
Block and brace irregular shapes. Flattened vehicles often have edges and corners that do not conform to standard trailer geometry. Use wood, rubber, or plastic blocking to fill gaps and prevent the load from rolling or tipping during braking or turns.
-
Test restraint tension after loading. Once the load is secured, manually try to move it. Pull on the cargo and the straps. There should be no play. Chains should be hand-tight and show no slack.
-
Perform a pre-trip walk-around. Before departure and at each fuel or rest stop, walk around your rig and verify that all chains, binders, and straps are in place and intact. Look for signs of shifting—scuff marks, fallen blocking, or loose fasteners.
-
Know your trailer limits. If you drive a Freightliner, Peterbilt, or similar make, review the manufacturer load-securement guidance for specialty haul configurations. Different trailers have different anchor points and weight distributions.
-
Document your securement method. If you are transporting for a junkyard, auto recycler, or specialty carrier, ask for written guidance on how the load should be secured. Carry that documentation. It can help during an inspection and provides you with a compliance standard.
If you receive a 393.126(c) citation, the vehicle will be placed out of service immediately. Do not attempt to drive further. Contact your dispatcher, secure the load properly, or arrange a tow-in. This is not a warning; it is a critical safety hold.
