What 393.126C1 means in plain language
FMSCR 393.126C1 addresses the secure transport of flattened or crushed vehicles. When you're hauling junked, wrecked, or otherwise compressed vehicles as cargo, those units must be properly secured so they cannot shift, tip, fall, or otherwise become a hazard during transit.
This isn't about hauling running vehicles or vehicle parts. This code applies specifically to the transport of whole vehicles that have been flattened or crushed—typically in auto recycling, demolition, or salvage operations. If you're moving such cargo, securing it correctly means using appropriate restraints, blocking, bracing, and tie-downs that account for the shape, weight distribution, and aerodynamic profile of the crushed unit.
Failure to do so puts other motorists at risk and triggers a citation at roadside inspection.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.126C1 is cited very rarely: just 5 citations all-time, with 3 citations in the last 12 months and zero in the last 90 days. This places the code at rank #2406 of 3,036 FMCSR codes by citation volume—it is a low-frequency violation.
However, when this code is cited, the consequences are severe. Our data shows a 100.0% out-of-service rate for all 5 citations on record. This is dramatically higher than the all-FMCSR average OOS rate of 31.4%. In other words, every single time an inspector cites 393.126C1, the vehicle is placed out of service immediately. There are no borderline cases or warnings in our dataset—the violation results in removal from the road.
The rarity of citations suggests that most carriers and drivers transporting crushed vehicles do comply. But when they don't, enforcement is swift and complete.
Who gets cited most
Our inspection records show only five citations for this code across all carriers and states. Because the violation is so infrequent, no single state or carrier dominates the data. Instead, citations are spread: PACKARD TRANSPORT LLC (USDOT 355502), SMOKEY'S INC (USDOT 758435), KJE ENTERPRISES LLC (USDOT 3276526), MILLENNIALS ENTERPRISE LLC (USDOT 3313243), and MILIS FLATWORK LLC (USDOT 3622621) each have one citation on record.
The vehicle makes cited most often are PTRB (2 citations) and KW, LAND, WANC, and WSTR (1 citation each). The small sample size reflects how specialized this cargo type is—only a subset of the trucking industry moves crushed vehicles regularly.
How severe is this compared to similar codes
Within the Vehicle Maintenance category, 393.126C1 stands apart in both frequency and outcome. For example, 393.9(a) (Inoperable required lamps) has 660,737 citations with a 15.4% OOS rate—it is cited far more often but results in out-of-service placement much less frequently. Similarly, 396.3(a)(1) (Inspection/repair/maintenance general) has 236,919 citations with a 45.3% OOS rate, again showing higher citation volume but lower severity per citation.
Codes like 396.17C-PI (No proof of periodic inspection) and 393.47E (Slack adjuster defective) have much higher citation counts (212,081 and 180,363 respectively) but 0.0% OOS rates. By contrast, 393.126C1's 100.0% OOS rate indicates that when inspectors find cargo securement failures on crushed vehicles, the risk assessment is absolute: the vehicle cannot continue in its current state.
How to avoid it
If you transport flattened or crushed vehicles, prevention begins with understanding your load:
-
Inspect securement before leaving the lot. Walk the perimeter of your load and verify that all tie-downs, chains, or straps are rated for the weight and shape of the crushed unit. Crushed vehicles can have sharp edges, irregular surfaces, and weight that shifts unexpectedly. Anchoring points must be sound.
-
Use appropriate restraint hardware. Chains, straps, and binders must be in good condition with no visible breaks, rust, or wear. Anchor points on both the tractor and the trailer must be free of damage. Crushed vehicles require robust securing—not the lighter securement used for palletized freight or small parts.
-
Account for load shift and aerodynamics. Crushed vehicles can catch wind differently than standard cargo. Ensure blocking and bracing prevents forward, rearward, or lateral movement during acceleration, braking, and turns. Gaps between the vehicle and the trailer bed should be minimized.
-
Document your securement method. Photograph the loaded trailer before departure. This isn't required by the regulation, but if you're cited, visual evidence of how you tied down the load helps demonstrate good-faith compliance.
-
Know your carrier's securement SOP. If you work for a carrier that hauls crushed vehicles, make sure you understand their specific securement procedures. Our data shows carriers such as MILIS FLATWORK LLC specialize in this work—they have procedures in place for a reason.
-
Never rely on the crushed vehicle's own features. Do not assume the flattened shape itself will stay in place. Treat every crushed unit as cargo that requires independent, redundant securement.
Because this violation carries a 100.0% out-of-service rate in our records, the stakes are high. One citation and you're off the road until the problem is corrected.
