393.128(b)(1) — Vehicle not secured, front and rear
FMCSA violation code under Vehicle Maintenance. 1,312 events recorded in roadside inspections. Severity weight: 7. Out-of-service eligible.
Violation code 393.128(b)(1) is a Federal Motor Carrier Safety Regulations citation issued under 49 CFR 393.128. 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) Vehicle Maintenance 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, 1,312 citations have been recorded against this code in the FMCSA inspection record.

How to use this code
CSA weight, OOS trigger, inspector focus, fix path, and DataQs — from published FMCSA fields and citation counts on this page
CSA / SMS weight
Severity weight 7 (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, 99.4% of 393.128(b)(1) citations (1,304 of 1,312) 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
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
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. Most-cited carrier in our table: URS MIDWEST LLC (18 citations). 992 carriers have at least one 393.128(b)(1) 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 393.128(b)(1)
- Locate the regulation in the eCFR. Open https://www.ecfr.gov/current/title-49/section-393.128 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 requirement carefully: "Vehicle not secured, front and rear" Map it to the specific equipment, driver document, or operational practice it covers.
- Inspect or maintain to standard. Build a recurring inspection or training routine that catches this defect before a roadside inspector does. Because 393.128(b)(1) 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.
- Document compliance to demonstrate it on review. Keep a dated, signed record of each inspection, repair, training session, or filing tied to 393.128(b)(1). 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.

Carriers who believe a citation was recorded in error can file a Request for Data Review through the FMCSA DataQs system.
