How to comply with violation code 392.2-SLLTR

  1. Locate the regulation in the eCFR. Open https://www.ecfr.gov/current/title-49/section-392.2 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: "Operating a commercial motor vehicle while the driver's ability or alertness is so impaired through fatigue, illness, or any other cause as to make it unsafe for the driver to begin or continue to operate the vehicle." Map it to the specific equipment, driver document, or operational practice it covers.
  4. 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.
  5. Document compliance to demonstrate it on review. Keep a dated, signed record of each inspection, repair, training session, or filing tied to 392.2-SLLTR. 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 392.2-SLLTR

What is FMCSA violation code 392.2-SLLTR?
Operating a commercial motor vehicle while the driver's ability or alertness is so impaired through fatigue, illness, or any other cause as to make it unsafe for the driver to begin or continue to operate the vehicle. The citation appears as code 392.2-SLLTR on roadside inspection reports issued by the Federal Motor Carrier Safety Administration and rolls up into the Unsafe Driving BASIC.
Is 392.2-SLLTR an out-of-service violation?
No. Code 392.2-SLLTR is not Out-of-Service eligible. A citation under this code is recorded on the inspection report and counts toward the carrier's BASIC percentile, but it does not by itself trigger an Out-of-Service order at the roadside.
What's the severity weight of 392.2-SLLTR?
392.2-SLLTR carries a severity weight of 8 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 392.2-SLLTR?
4,491 inspections in our FMCSA mirror cite 392.2-SLLTR, of which 1 (0.0%) 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 392.2-SLLTR in?
392.2-SLLTR rolls up into the Unsafe Driving 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 392.2-SLLTR?
Resolving a 392.2-SLLTR 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.
Where can I find related violation codes?
The "Often Cited Together" panel on this page lists violations frequently appearing on the same inspection as 392.2-SLLTR — these usually share a root cause (for example, an HOS violation paired with a logbook error). The All Violation Codes index links to every code in the system, and the BASIC category page lists every code in Unsafe Driving.
Where can I find the full text of 392.2-SLLTR?
The full regulatory text is published on eCFR.gov at 49 CFR 392.2. 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.

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.
