FMCSA violation code under Hazardous Materials. 324 events recorded in roadside inspections. Severity weight: 7. Out-of-service eligible.

OOS Eligible

Violation code 180.407(a) is a Federal Motor Carrier Safety Regulations citation issued under 49 CFR 180.407. 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) Hazardous Materials 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, 324 citations have been recorded against this code in the FMCSA inspection record.

How to comply with violation code 180.407(a)

  1. Locate the regulation in the eCFR. Open https://www.ecfr.gov/current/title-49/section-180.407 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: "Cargo tank not inspected or tested as required." 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 180.407(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 180.407(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 180.407(a)

What is FMCSA violation code 180.407(a)?
Cargo tank not inspected or tested as required. The citation appears as code 180.407(a) on roadside inspection reports issued by the Federal Motor Carrier Safety Administration and rolls up into the Hazardous Materials BASIC.
Is 180.407(a) an out-of-service violation?
Yes. Code 180.407(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 180.407(a)?
180.407(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 180.407(a)?
324 inspections in our FMCSA mirror cite 180.407(a), of which 6 (1.9%) resulted in Out-of-Service orders. The Recent Inspections table on this page lists the most recent citations with date, state, level, and OOS flag — click any row to see the full inspection report.
Which BASIC category is 180.407(a) in?
180.407(a) rolls up into the Hazardous Materials 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 180.407(a)?
Resolving a 180.407(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.
How is 180.407(a) different from FMCSR section 180.407?
180.407 is the section heading; 180.407(a) is the specific sub-paragraph cited under that section. FMCSA tracks each enforceable paragraph as its own violation code so the inspection record can pinpoint exactly which requirement the carrier failed. Citations roll up to the section-level total but the per-paragraph code is what carries severity and OOS eligibility.
Where can I find the full text of 180.407(a)?
The full regulatory text is published on eCFR.gov at 49 CFR 180.407. 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.
