CSA / SMS weight

Severity weight 2 (1–10). Higher weights correlate more strongly with crash risk in FMCSA's published table. Rolls into the Vehicle Maintenance 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. In our mirror, 78.6% of 396.5A-HNLOW citations (429 of 546) carried an OOS flag.

What inspectors typically check

FMCSR violations for brake defects, tire issues, lighting failures, frame damage, and other mechanical deficiencies.

  • Brake condition, adjustment, and air-system integrity
  • Tire tread/condition, lighting, and reflectors
  • Frame, coupling, cargo securement, and other mechanical defects

Vehicle Maintenance category →

Fix and prevent

  • Correct the underlying condition before the next trip — an OOS-eligible finding can park the truck or driver immediately.
  • Catch it on pre-trip and scheduled PM before a roadside Level I/II does — brakes, tires, and lamps dominate this BASIC.
  • 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

Severity 2/10 — weigh frequency and recency on the carrier's inspection history, not a single old citation. OOS-eligible: a fresh citation can mean the load was interrupted at roadside until repaired. Most-cited carrier in our table: CROWN XPRESS TRANSPORT INC (6 citations). 411 carriers have at least one 396.5A-HNLOW citation in the mirror — open a carrier's inspection list to see whether this code is a pattern or a one-off.

How to comply with violation code 396.5A-HNLOW

  1. Locate the regulation in the eCFR. Open https://www.ecfr.gov/current/title-49/section-396.5 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: "HUBS - No Visible Or Measurable Lubricant Showing In The HUB - Outer Wheel" 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 396.5A-HNLOW 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 396.5A-HNLOW. 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): 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.

TruckCodex mirrors the FMCSA Motor Carrier Management Information System (MCMIS) and the published violation dictionary on a daily refresh cycle. We do not author or modify violation records — every count, severity weight, and OOS flag on this page reflects what the FMCSA has on file. For real-time confirmation immediately before an enforcement decision, click through to the FMCSA Violations Search link above. Carriers who believe a citation was recorded in error can file a Request for Data Review through the FMCSA DataQs system.
