FMCSR 392.16(b) Seat Belt Violation: Driver Q&A

Almost certainly not. Across all 4,329 citations for 392.16(b) in our inspection records, only 3 resulted in an out-of-service order—that's a 0.1% OOS rate. The code is not OOS-eligible under the standard criteria, so inspectors have virtually no pathway to park you on the spot for this alone. For context, the average OOS rate across all FMCSR codes in our database is 31.4%, making 392.16(b) one of the least likely violations to take you off the road immediately.

392.16(b) carries a severity weight of 3 in the CSA scoring system, which is on the lower end of the Unsafe Driving BASIC. That base score gets multiplied depending on how recently the violation occurred—citations within the last 6 months receive the highest multiplier (3×), dropping to 2× between 6 and 12 months, and 1× between 12 and 24 months. After 24 months, the violation ages out of your CSA percentile calculation entirely. The 3-point severity weight means it won't spike your Unsafe Driving BASIC the way a higher-weight violation would, but repeated citations stack fast.

Start with documentation, today. Here's a concrete checklist:

1. Get a copy of the inspection report (the roadside inspector should have provided one).
2. Verify the vehicle information is accurate—our records show Ford, Freightliner, and International vehicles account for a large share of 392.16(b) citations, so confirm the listed vehicle make and DOT number match yours.
3. Check your seat belt assembly—if the belt was malfunctioning or missing, document that now with photos, as it's relevant to a potential DataQs challenge.
4. Notify your fleet safety manager—the citation will post to your PSP record and your carrier's SMS data.
5. Note the inspection date—the 3× CSA multiplier applies for the first 6 months after citation.

It's real, but it's one of the lower-impact violations in the Unsafe Driving BASIC. Our inspection database shows 392.16(b) has accumulated 4,329 all-time citations, ranking it #372 out of 3,036 FMCSR codes by volume—active but not among the most-cited codes. Compare that to peer code 392.2 (operating while ill or fatigued), which has 1,208,164 citations in our records. The 0.1% OOS rate for 392.16(b) also sits far below the all-FMCSR average of 31.4%, confirming enforcement is largely advisory rather than equipment-stopping. The CSA severity weight of 3 is lower than many Unsafe Driving codes, but the violation still lands in a BASIC category that FMCSA scrutinizes closely during safety fitness determinations.

Yes, you can submit a DataQs Request for Data Review (RDR) for any roadside inspection finding, including 392.16(b). The process goes through FMCSA's DataQs portal and routes your challenge to the issuing state agency for review. Because 392.16(b) is an observed behavior violation—not an equipment defect with a repair receipt—successful challenges typically rely on factual errors in the inspection report: wrong driver name, wrong vehicle, wrong date, or a belt assembly that was actually functional and in use. If the inspector's observation is accurately recorded, the bar for removal is high. Still, with 0 citations recorded in the last 90 days for this code, inspectors writing 392.16(b) are doing so deliberately, so review the report carefully before filing.

Our inspection records do not include a state-level breakdown for 392.16(b) in the current data snapshot, so naming specific states with citation counts isn't possible here without inventing numbers. What the data does show is that Ford vehicles received 388 citations under this code—the most of any vehicle make—followed by Freightliner variants with 261 and 213 citations respectively, and International vehicles with 160 and 142. This suggests the violation is distributed across diverse fleets and vehicle types rather than concentrated in one region, but check the TruckCodex state detail page for 392.16(b) once state-level filters are applied to your search.

Address it before your next trip. The 90-day citation volume for 392.16(b) in our records is 0, meaning active enforcement has been quiet recently—but that doesn't reduce your obligation. A functioning, properly installed seat belt assembly is required any time you operate a CMV equipped with one. More practically, a second citation within 6 months doubles your CSA exposure because both violations would carry the maximum 3× time multiplier simultaneously. With a severity weight of 3 per citation, two violations in a short window can meaningfully move your Unsafe Driving BASIC percentile. Inspect the belt assembly, confirm it latches and retracts correctly, and document the check in your pre-trip inspection records.

Both. Under FMCSA's CSA system, Unsafe Driving BASIC violations are attributed to the driver's Pre-Employment Screening Program (PSP) record and to the carrier's Safety Measurement System (SMS) profile simultaneously. The carrier takes the hit in their Unsafe Driving BASIC, which factors into their SMS percentile ranking and can trigger FMCSA interventions. The driver's PSP record retains the violation for 3 years, and prospective employers pulling a PSP report will see it. Our records show carriers like BUILDER SERVICES GROUP INC (17 citations) and HOME EXPRESS DELIVERY SERVICE LLC (13 citations) have accumulated the most 392.16(b) citations among named carriers—evidence that repeated driver-level behavior aggregates into a measurable carrier-level problem.
