How to comply with FMCSR section 172.331A
- Locate the regulation in the eCFR. Open https://www.ecfr.gov/current/title-49/section-172.331 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.
- 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.
- Identify the documented requirement. Read the regulation text from Step 1 and identify the specific equipment, driver document, or operational practice the rule covers. Citations under 172.331A hinge on whether that specific requirement was met at the moment of the inspection.
- Inspect or maintain to standard. Build a recurring inspection, training, or filing routine that catches this gap before a roadside inspector does. Pre-trip checks, scheduled preventive maintenance, driver-qualification file audits, and supervisor reviews are the standard places this kind of issue is caught early.
- Document compliance to demonstrate it on review. Keep a dated, signed record of each inspection, repair, training session, or filing tied to 172.331A. 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.

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). Each code carries a published severity weight (1–10) and an Out-of-Service eligibility flag.
Section headings (like the one on this page) aren't themselves enforceable codes — FMCSA inspectors cite the specific paragraph that the carrier failed, and FMCSA's violation dictionary tracks each paragraph as its own row. The aggregate view here sums citations issued against every sub-paragraph of 172.331A, including out-of-service rate, top enforcing states, most-cited carriers, and recent inspections. Pick a sub-paragraph above to see its specific definition, severity weight, and citation trend.
TruckCodex mirrors the FMCSA Motor Carrier Management Information System (MCMIS) and the published violation dictionary on a daily refresh cycle. Carriers who believe a citation was recorded in error can file a Request for Data Review through the FMCSA DataQs system within 24 months of the inspection date.
