This is a specific FMCSA dictionary variant of section 393.116; it is not interchangeable with the bare 393.116 catch-all code.

CSA/SMS severity weight 7 on FMCSA's 1–10 scale in the Vehicle Maintenance BASIC.

Out-of-service eligible — an inspector can place the driver or vehicle out of service until the condition is corrected. Observed OOS rate in our mirror: 100.0% (1 of 1 citations).

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, 100.0% of 393.116D1 citations (1 of 1) 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

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: BALDWIN LUMBER COMPANY (1 citations). 1 carriers have at least one 393.116D1 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 393.116D1

  1. Locate the regulation in the eCFR. Open https://www.ecfr.gov/current/title-49/section-393.116 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: "Shortwood log extends more than 1/3 of logs total length beyond supporting structure of vehicle" 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 393.116D1 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 393.116D1. 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 393.116D1

What is FMCSA violation code 393.116D1?
Shortwood log extends more than 1/3 of logs total length beyond supporting structure of vehicle The citation appears as code 393.116D1 on roadside inspection reports issued by the Federal Motor Carrier Safety Administration and rolls up into the Vehicle Maintenance BASIC.

Yes. Code 393.116D1 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 393.116D1?
393.116D1 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 393.116D1?
1 inspections in our FMCSA mirror cite 393.116D1, of which 1 (100.0%) 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 393.116D1 in?
393.116D1 rolls up into the Vehicle Maintenance 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 393.116D1?
Resolving a 393.116D1 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.

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.
