392.9a(a) — Operating beyond scope of authority

FMCSA violation code under General/Admin. Severity weight: 7. Out-of-service eligible.

OOS Eligible

Violation code 392.9a(a) is a Federal Motor Carrier Safety Regulations citation issued under 49 CFR 392.9. It tracks a specific compliance failure recorded against motor carriers and drivers during FMCSA roadside inspections. The code rolls up into the FMCSA Safety Measurement System (SMS) General/Admin BASIC, which feeds the carrier's percentile ranking and prioritization for FMCSA interventions. It applies to interstate motor carriers, drivers, and the commercial motor vehicles they operate; intrastate operators are subject when their state has adopted Part 350 of the FMCSR by reference. It carries a severity weight of 7, an inspection citing it can trigger an Out-of-Service order at the roadside.

CSA / SMS weight

Severity weight 7 (1–10). Higher weights correlate more strongly with crash risk in FMCSA's published table. Rolls into the General/Admin BASIC. SMS applies time weights (3× / 2× / 1×) over a 24-month window before ranking carriers by percentile.

OOS trigger

This code is OOS-eligible under CVSA Out-of-Service Criteria. A roadside finding can stop the trip until the defect or condition is corrected.

What inspectors typically check

Administrative and general regulatory violations including operating authority, insurance filing, and registration requirements.

  • Operating authority and insurance filing status
  • USDOT marking / URS registration requirements
  • Lease, interchange, and other administrative filings

General/Admin category →

Fix and prevent

  • Correct the underlying condition before the next trip — an OOS-eligible finding can park the truck or driver immediately.
  • Build a recurring check (pre-trip, file audit, or supervisor review) that targets the requirement in the regulation text above.
  • Keep the correction in the compliance file — undocumented fixes look the same as non-compliance in a review.

DataQs challenge grounds

Carriers and drivers can file a Request for Data Review within 24 months when the record itself looks wrong. Common accepted grounds:

  • Wrong violation code for the condition the inspector described
  • Citation attributed to the wrong USDOT, driver, or unit
  • Condition was already corrected / not present when the report was finalized
  • Supporting evidence (photos, receipts, calibration, ELD extract) contradicts the citation

For brokers and shippers

High severity (7/10) — repeated citations on a carrier's recent inspections are a stronger diligence flag than low-weight administrative codes. OOS-eligible: a fresh citation can mean the load was interrupted at roadside until repaired.

Violation Description

Motor carrier operating in interstate/foreign commerce beyond the scope of its operating authority.

Regulatory Reference

Federal Motor Carrier Safety Regulations

This violation references 49 CFR 392.9a in the Federal Motor Carrier Safety Regulations.

How to comply with violation code 392.9a(a)

  1. Locate the regulation in the eCFR. Open https://www.ecfr.gov/current/title-49/section-392.9 on eCFR.gov to read the legal text the citation is written against. The eCFR is the National Archives' continuously updated electronic Code of Federal Regulations and is the canonical reference for any FMCSR section.
  2. Determine if your operation is subject. Confirm whether your operation is interstate (always subject to the FMCSR) or intrastate (subject when your state has adopted 49 CFR Part 350 by reference; most have). Intrastate operators in non-adopting states may be subject to a state analog instead of the federal rule.
  3. Identify the documented requirement. Read the requirement carefully: "Motor carrier operating in interstate/foreign commerce beyond the scope of its operating authority." Map it to the specific equipment, driver document, or operational practice it covers.
  4. Inspect or maintain to standard. Build a recurring inspection or training routine that catches this defect before a roadside inspector does. Because 392.9a(a) is OOS-eligible, a single citation can park the truck or driver until the condition is corrected — pre-trip checks, scheduled PMs, and supervisor reviews are the cheap places to find it.
  5. Document compliance to demonstrate it on review. Keep a dated, signed record of each inspection, repair, training session, or filing tied to 392.9a(a). During an FMCSA compliance review or a customer onboarding audit, the documentation is what proves the program runs — undocumented compliance is indistinguishable from non-compliance to the auditor.

Frequently asked questions about 392.9a(a)

What is FMCSA violation code 392.9a(a)?
Motor carrier operating in interstate/foreign commerce beyond the scope of its operating authority. The citation appears as code 392.9a(a) on roadside inspection reports issued by the Federal Motor Carrier Safety Administration and rolls up into the General/Admin BASIC.
Is 392.9a(a) an out-of-service violation?
Yes. Code 392.9a(a) is Out-of-Service eligible. When this violation is found at a roadside inspection, the inspector can place the driver or vehicle out of service immediately under the CVSA Out-of-Service Criteria, blocking continued operation until the condition is corrected.
What's the severity weight of 392.9a(a)?
392.9a(a) carries a severity weight of 7 on FMCSA's 1–10 scale. Higher weights indicate violations more strongly correlated with crash risk; FMCSA multiplies the weight by a time factor (3× for citations 0–6 months old, 2× for 6–12 months, 1× for 12–24 months) when computing the carrier's Safety Measurement System percentile.
How many inspections have cited 392.9a(a)?
Our mirror of the FMCSA inspection record currently shows no citations against 392.9a(a). Either the code is rarely used in the field, or it's a recent addition that hasn't accumulated citations in our 24-month rolling window. Check the FMCSA Violations Search link on this page for the most recent enforcement data.
Which BASIC category is 392.9a(a) in?
392.9a(a) rolls up into the General/Admin BASIC of FMCSA's Safety Measurement System. The BASIC determines how the citation feeds the carrier's percentile ranking — carriers with high percentiles in a BASIC are prioritized for FMCSA interventions including warning letters, focused investigations, and full compliance reviews.
What does a carrier do to fix 392.9a(a)?
Resolving a 392.9a(a) citation has two parts: (1) correct the underlying condition immediately — repair the equipment defect, retrain the driver, file the missing form, or update the maintenance record — and (2) document the correction in the carrier's compliance file, ideally with date, time, and the name of the person who performed the work. Carriers that believe the citation was recorded in error can file a Request for Data Review through the FMCSA DataQs system within 24 months of the inspection date.
Where can I find related violation codes?
The "Often Cited Together" panel on this page lists violations frequently appearing on the same inspection as 392.9a(a) — these usually share a root cause (for example, an HOS violation paired with a logbook error). The All Violation Codes index links to every code in the system, and the BASIC category page lists every code in General/Admin.
Where can I find the full text of 392.9a(a)?
The full regulatory text is published on eCFR.gov at 49 CFR 392.9. The eCFR is the official, continuously updated electronic Code of Federal Regulations maintained by the National Archives. The TruckCodex page mirrors enforcement data; the eCFR has the legal text the citation is written against.

About FMCSA violation codes

Every violation found during an FMCSA roadside inspection is recorded under a code drawn from the Federal Motor Carrier Safety Regulations — the codified safety rules motor carriers, drivers, and commercial motor vehicles must comply with in interstate commerce. Codes roll up into one of seven Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, Hours-of-Service, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and Crash Indicator. Each code carries a published severity weight (1–10) and an Out-of-Service eligibility flag.

Citations counted in the FMCSA Safety Measurement System (SMS) feed a 24-month rolling percentile rank for every motor carrier. Recent citations weigh more heavily than older ones — FMCSA applies a 3× multiplier to events 0–6 months old, 2× for 6–12 months, and 1× for 12–24 months. Carriers above the published intervention threshold for a given BASIC are prioritized for warning letters, focused investigations, and full compliance reviews.
