What 392.9A2 means in plain language
This regulation requires that before a commercial motor vehicle moves, the driver must make sure all equipment on the vehicle is properly secured. That means anything that could shift, fall, or become a hazard while the truck is in motion needs to be fastened down, stowed correctly, or otherwise made safe before you pull away.
The rule isn't limited to cargo in a trailer — it covers equipment that's part of the vehicle itself: tools, straps, chains, binders, tarps, spare tires, load securement gear, and any other items that travel with the rig. If it's loose and it's on your vehicle, it's your responsibility.
In practical terms, an inspector who spots unsecured equipment during a roadside check — whether it's a loose chain dangling from a flatbed, an unfastened strap flapping in the wind, or a tool bouncing around in a truck bed — has grounds to write this citation. The fix sounds simple, but the enforcement numbers tell a different story about how often drivers are caught off guard.
What our enforcement data actually shows
The numbers here are striking. Across our 13 million+ inspection records, 392.9A2 carries an all-time out-of-service rate of 96.1% — meaning that when an inspector cites this violation, the truck is almost certainly going nowhere until the problem is corrected. To put that in context, the all-FMCSR average OOS rate across all codes is 31.4%. This code runs more than three times that average.
That said, 392.9A2 is officially marked as not OOS-eligible under the standard OOS criteria. Yet our data shows 3,112 out of 3,238 all-time citations resulted in the vehicle being placed out of service. That gap between the formal eligibility designation and real-world enforcement outcomes is worth taking seriously. Inspectors clearly have discretion here, and they're using it.
In terms of volume, our inspection records show 955 citations in the last 12 months and 182 citations in the last 90 days alone. The monthly trend data shows persistent enforcement activity — July 2025 was the highest recorded month in the trailing year with 116 citations, all 116 of which resulted in an OOS placement. Even in lower-volume months like December 2025, 62 of 63 citations led to an OOS order. This is not a code that inspectors write and walk away from.
Nationally, 392.9A2 ranks #422 out of 3,036 FMCSR codes by citation volume — not in the top tier, but active enough that encounter risk is real, especially in certain states.
Who gets cited most
Looking at the last 180 days in our database, Texas leads all states with 148 citations — and every single one of them, all 148, resulted in an OOS placement, a 100.0% rate. New Mexico is close behind with 118 citations, also at a 100.0% OOS rate. Iowa comes in third with 56 citations and a 98.2% OOS rate.
The variation becomes more noticeable when you look further down the list. Illinois recorded 33 citations with a 78.8% OOS rate — still high, but meaningfully lower than Texas and New Mexico. Pennsylvania had only 2 citations with a 50.0% OOS rate. If you run routes through Texas or New Mexico, the data in our database makes clear that enforcement here is essentially binary: get cited, get shut down.
On the carrier side, our data shows fleets such as TRANSPORTES ESPECIALIZADOS ANTONIO GARZA RUIZ SA DE CV (USDOT 736463) with 8 all-time citations and TRANSPORTATION AND CARGO SOLUTIONS S DE RL DE CV (USDOT 779973) with 7 citations appearing at the top of the citation count list. The concentration of Mexican-domiciled carriers in the top carrier list aligns with the heavy citation activity in Texas and New Mexico — border crossing inspection corridors are clearly a high-enforcement environment for this code.
How severe is this compared to similar codes
Within the Unsafe Driving category, 392.9A2 stands out sharply on OOS rate even though its citation volume is modest by comparison. Consider a few peers from the same category:
- 392.2 (Operating a CMV while ill or fatigued) has 1,208,164 all-time citations in our database — nearly 373 times the volume of 392.9A2 — but carries only a 0.8% OOS rate. That's a code inspectors write frequently but rarely use to put a truck out of service.
- 392.2RG (Operating a CMV while ill or fatigued) has 96,652 citations with a 0.1% OOS rate. Again, high volume, minimal OOS impact.
- 392.2-SLLEQP (Operating a CMV while ill or fatigued) has 72,352 citations with a 2.4% OOS rate — still nowhere close to the 96.1% seen with 392.9A2.
The pattern is consistent: most codes in the Unsafe Driving category generate large citation counts with low OOS rates. 392.9A2 flips that script — lower citation count, but an OOS rate that dwarfs its peers. If you're cited for this code, the probability of being sidelined is near certain.
How to avoid it
The co-occurring violation data from our last 90 days of inspections points to a clear picture: 392.9A2 rarely shows up alone. It appears alongside lighting violations, inspection paperwork gaps, equipment defects, and even licensing issues. That tells you inspectors who find unsecured equipment are doing thorough walkarounds — which means your pre-trip inspection needs to be equally thorough.
Fremont (FRHT) vehicles account for 859 all-time citations under this code, more than any other make, followed by Kenworth (KW) at 498 and Peterbilt (PTRB) at 369. If you're behind the wheel of one of these trucks, pay attention.
Here's what to build into your pre-trip routine:
- Walk the entire perimeter of the truck and trailer specifically looking for anything that isn't fixed in place — loose straps, hanging chains, unsecured binders, or tools left on the frame rail or steps.
- Check all load securement hardware even if you're not carrying freight. Empty flatbeds and tankers still need chains, straps, and binders properly stowed.
- Inspect your lights and reflectors before moving — 393.9 (inoperable required lamp) appeared in 46 shared inspections in the last 90 days alongside 392.9A2. An inspector who stops you for a light is going to keep looking.
- Have your periodic inspection documentation on hand — 396.17C (no proof of periodic inspection) appeared in 33 shared inspections. A paperwork gap signals to an inspector that your maintenance culture may have other holes.
- Check your fire extinguisher mount and cab equipment — 393.95A (fire extinguisher missing or defective) appeared in 30 shared inspections. A loose or unsecured extinguisher can itself contribute to an unsecured equipment finding.
- Verify your windshield condition — 393.78 (defective windshield condition) appeared in 31 shared inspections. Inspectors doing a full write-up are checking everything they can see from the cab outward.
The bottom line: 392.9A2 is the kind of violation that shows up when a driver skipped steps on the pre-trip. Our data shows that skipping those steps in Texas or New Mexico means a near-certain OOS order. Ten minutes on the pre-trip is a far better outcome than sitting at a weigh station waiting for a release.
