172.600(c) — Emergency response information not available

FMCSA violation code under Hazardous Materials. 941 events recorded in roadside inspections. Severity weight: 6.

Violation code 172.600(c) is a Federal Motor Carrier Safety Regulations citation issued under 49 CFR 172.600. 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) Hazardous Materials 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 6, 941 citations have been recorded against this code in the FMCSA inspection record.

How to comply with violation code 172.600(c)

  1. Locate the regulation in the eCFR. Open https://www.ecfr.gov/current/title-49/section-172.600 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: "Emergency response information for hazardous materials not immediately available during transport." 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 172.600(c). 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 172.600(c)

What is FMCSA violation code 172.600(c)?
Emergency response information for hazardous materials not immediately available during transport. The citation appears as code 172.600(c) on roadside inspection reports issued by the Federal Motor Carrier Safety Administration and rolls up into the Hazardous Materials BASIC.
Is 172.600(c) an out-of-service violation?
No. Code 172.600(c) 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 172.600(c)?
172.600(c) carries a severity weight of 6 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 172.600(c)?
941 inspections in our FMCSA mirror cite 172.600(c), of which 4 (0.4%) 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 172.600(c) in?
172.600(c) rolls up into the Hazardous Materials 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 172.600(c)?
Resolving a 172.600(c) 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.
How is 172.600(c) different from FMCSR section 172.600?
172.600 is the section heading; 172.600(c) is the specific sub-paragraph cited under that section. FMCSA tracks each enforceable paragraph as its own violation code so the inspection record can pinpoint exactly which requirement the carrier failed. Citations roll up to the section-level total but the per-paragraph code is what carries severity and OOS eligibility.
Where can I find the full text of 172.600(c)?
The full regulatory text is published on eCFR.gov at 49 CFR 172.600. 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.
