What 392.9 means in plain language
FMCSR 392.9 puts the responsibility squarely on the driver: before you move a commercial motor vehicle, the cargo on or in that vehicle must be properly secured. It doesn't matter whether you loaded it yourself, whether a shipper sealed the trailer, or whether a dock crew signed off. If the load isn't secured to federal standards when you're behind the wheel, you are the person on the hook at the roadside.
The rule covers all forms of cargo securement — tie-downs, chains, straps, binders, blocking, bracing — and requires that they be adequate for the weight, shape, and behavior of the load being transported. A strap that was tight at the shipper's dock can loosen over miles of vibration. A load that looked stable can shift after the first hard brake. The standard is continuous: the load must be properly secured for the entire trip, not just when you pull away.
If a roadside inspector determines that your securement is inadequate — too few tie-downs, wrong rating, broken hardware, or missing blocking — 392.9 is the citation you'll receive. Unlike some equipment violations, this one lands on the driver record, not just the vehicle.
What our enforcement data actually shows
Across our 13 million+ inspection records, FMCSR 392.9 has generated 3,878 all-time citations, placing it at rank #396 out of 3,036 FMCSR codes by citation volume. That puts it solidly in the upper tier of enforcement activity — not the most-cited code on the books, but far from obscure.
The number that should get your full attention is the out-of-service rate. Our inspection records show that 3,029 of those 3,878 citations resulted in an out-of-service order — an OOS rate of 78.1%. To put that in context, the all-FMCSR average OOS rate across every code in our database is 31.4%. FMCSR 392.9 runs nearly 2.5 times that average. Even though the code itself is not formally designated as OOS-eligible under the standard North American criteria, the data shows that inspectors are placing drivers out of service at a dramatically elevated rate when they write this violation.
Enforcement has remained active over the past year. Our database recorded 638 citations in the last 12 months and 107 citations in the last 90 days alone. Looking at the monthly trend, activity peaked at 81 citations in July 2025 and has generally stayed in the 40–75 range month over month. There is no sign this code is being deprioritized at the roadside.
Who gets cited most
Texas dominates the geographic picture. In the last 180 days, our inspection records show Texas generated 176 citations for 392.9 — far ahead of any other state. Of those, 155 resulted in an OOS order, giving Texas an 88.1% OOS rate for this code. If you run lanes in Texas, the combination of high volume and high OOS rate makes this a priority violation to understand before you leave the yard.
Illinois comes in second with 59 citations in the same period, but with a notably different enforcement pattern: only 13 of those citations led to an OOS order, a 22.0% rate. That 66-percentage-point gap between Texas and Illinois isn't a data quirk — it reflects real variation in how inspectors apply out-of-service decisions for securement violations from state to state.
North Carolina rounds out the top three with 6 citations and a 66.7% OOS rate, consistent with the national trend of most 392.9 encounters resulting in a driver being put out of service.
On the carrier side, our data shows fleets such as SMYRNA READY MIX CONCRETE LLC (USDOT 1738904) with 10 all-time citations and MR BULT'S INC (USDOT 387102) with 9 citations appearing at the top of the carrier list. The concentration in concrete, construction materials, and waste hauling is not coincidental — bulk and heavy-commodity operations face the highest exposure to securement scrutiny.
By vehicle make, Freightliner (FRHT) leads all-time with 485 citations, followed by Kenworth (KW) at 290 and Peterbilt (PTRB) at 245. These are simply the most common heavy-duty platforms on the road, so the volume reflects fleet size as much as any make-specific risk.
How severe is this compared to similar codes
FMCSR 392.9 sits in the Unsafe Driving category alongside several other 392-series codes. The comparison is striking.
392.2 — Operating a CMV while ill or fatigued — is the highest-volume code in the category with 1,208,164 all-time citations, but carries only a 0.8% OOS rate. Inspectors write it constantly, but rarely pull drivers out of service for it. FMCSR 392.9, by contrast, has 3,878 citations and a 78.1% OOS rate. It is cited far less often, but when it is written, the consequences are severe.
392.2RG, another fatigue-related sub-code, shows 96,652 citations at a 0.1% OOS rate — again, high volume, low OOS consequence. FMCSR 392.9 is essentially the inverse: lower citation frequency, but an OOS outcome in roughly four out of every five encounters our database records.
392.2-SLLEQP carries 72,352 citations and a 2.4% OOS rate, the highest among the fatigue sub-codes, but still a fraction of what 392.9 produces. Within its peer category, 392.9 is uniquely punishing in terms of out-of-service outcomes per citation written.
How to avoid it
The co-occurring violation pattern in our data tells you exactly where inspectors are finding problems during the same inspections that produce a 392.9 citation. Use that pattern to build your pre-trip.
- Audit every tie-down before departure. Count your tie-downs, check the working load limit rating on each strap or chain, and verify that the number and type are appropriate for your commodity. A strap that looks intact can have a frayed core — replace it before the trip, not at the roadside.
- Check all required lamps — especially after loading. 393.9 (Inoperable Required Lamp) appeared in 42 of the same inspections as 392.9 in the last 90 days. Cargo loading and tarping operations frequently knock out marker and clearance lamps. Walk the full perimeter of the trailer after loading, before you pull out.
- Inspect brake components explicitly. Our data shows 396.3A1BOS (brakes out of service), 393.45B2UV (brake tubing/hoses inadequate), and 393.47E (slack adjuster defective) all co-occur with 392.9 citations. Inspectors who find one problem look harder for others. Check brake adjustment and visible air lines as part of every pre-trip.
- Carry and check your fire extinguisher. 393.95A (fire extinguisher missing or defective) appeared in 25 of the same inspections. Confirm the extinguisher is mounted, accessible, charged, and undamaged before you leave — it takes 30 seconds.
- Check your windshield. 393.78 (defective windshield condition) was flagged in 24 shared inspections. A cracked or obscured windshield is a separate violation, but its presence in the same inspection suggests these are not targeted enforcement stops — they are thorough walk-arounds.
- Verify your last periodic inspection documentation is on board. 396.17C (no proof of periodic inspection) appeared in 26 shared inspections. Carry the current inspection report and make sure the date is valid.
- Re-check securement after the first 50 miles. Load shift is most common in the early miles. A brief stop to inspect tie-down tension can prevent the citation that an inspector would write 200 miles down the road.
