What 393.120B1 means in plain language
When you're transporting metal coils—whether they're steel, aluminum, or other materials—federal regulations require that they be secured in a specific way. 393.120B1 enforces rules that govern how metal coils must be restrained and positioned on your vehicle to prevent shifting, rolling, or falling during transport.
The regulation covers the exact methods, tie-down materials, and placement requirements that apply uniquely to metal coils. Unlike general cargo securement, coils have their own rules because of their shape, weight distribution, and the risks they pose if they shift or become dislodged. An inspector checking your load will verify that your securement method matches these specific standards, not just generic load-tie procedures.
If your citation says metal coils were not secured according to these rules, it means the inspector found that your tie-downs, blocking, or positioning didn't meet the standard for this cargo type. That could mean insufficient restraint, improper edge protection, or failure to follow the prescribed securement geometry.
What our enforcement data actually shows
Across 13 million inspection records in our database, 393.120B1 has generated only 3 all-time citations, with 1 citation in the last 12 months and 0 in the last 90 days. This makes it one of the rarest violations we see—ranked #2551 out of 3,036 FMCSR codes by citation volume.
What is striking about this code's enforcement pattern is its out-of-service rate. Every single citation on record—3 out of 3—resulted in the vehicle being placed out of service. That's a 100.0% OOS rate, compared to the all-FMCSR average of 31.4%. This tells you that when inspectors cite this violation, they view it as serious enough to stop the vehicle immediately. The cargo securement failure is not treated as a minor paperwork issue or a correctable defect; it's treated as a safety hazard that grounds the truck.
The low citation volume combined with the 100% OOS rate suggests that metal coil securement is either handled correctly by most carriers, or that when it is found deficient, the severity triggers an immediate shutdown.
Who gets cited most
Our inspection records show that in the last 180 days, Illinois was the only state with a recorded citation for 393.120B1—1 citation, placed out of service. With such limited enforcement volume nationwide, state-level variation is minimal and not meaningful for trend analysis.
Across all-time records, our data shows carriers such as Valley Transportation Service Inc (USDOT 456821), Keep Trucking LLC (USDOT 2262722), and FCM Trucking Services Inc (USDOT 2384169) each with 1 citation for this code. These represent isolated incidents in our 13 million inspection dataset, not patterns of systemic non-compliance.
How severe is this compared to similar codes
Vehicle maintenance codes in the same FMCSR category show very different enforcement patterns. Inoperable required lamps (393.9(a)) has generated 660,737 citations with a 15.4% OOS rate—vastly more frequent but less likely to result in immediate removal. Inspection and repair maintenance violations (396.3(a)(1)) show 236,919 citations with a 45.3% OOS rate, indicating they're serious when cited but still less commonly placed out of service than 393.120B1.
By comparison, slack adjuster defects (393.47E)—a brake safety issue—generated 180,363 citations but only a 0.0% OOS rate in our records, meaning inspectors typically give drivers time to repair rather than stopping the vehicle. The 100% OOS rate on 393.120B1 is exceptional within this category and reflects the immediate danger posed by unsecured metal coils.
How to avoid it
If you haul metal coils, your pre-trip and cargo securement checklist should include these driver-actionable steps:
-
Know the specific rules for metal coils before you load. Metal coils have their own securement geometry and tie-down requirements in the regulations. Review them before pickup, or ask your dispatcher for a quick briefing. Don't assume general cargo rules apply.
-
Inspect tie-downs and edge protection before departure. Check that all restraint straps, chains, or cables are routed and tensioned according to the metal-coil standard. Look for chafing points where coils might contact sharp edges, and confirm edge protection is in place.
-
Verify proper load positioning on the trailer. Metal coils must sit in the right location and orientation. If a coil is positioned too far forward, too far back, or at the wrong angle, it creates shifting risk. Make sure blocking or cradles are correct before you leave the yard.
-
Double-check restraint integrity at every stop. Metal coils can settle slightly during transport. At fuel stops or rest breaks, visually inspect that tie-downs haven't loosened and that no movement has occurred.
-
Communicate with your carrier about coil loads. If you're assigned a load with metal coils and you're not confident in the securement, speak up to your safety manager or dispatcher. A 100% OOS rate on this violation means inspectors will not give you a chance to fix it roadside—it results in shutdown.
The rarity of this citation in our 13 million inspection records suggests that most drivers and carriers get it right. But when it is cited, the consequence is immediate. Treat metal coil securement as non-negotiable.
