FMCSR 172.602(b): Emergency Response Information Citations

No. Across our 13 million inspection records, citations for 172.602(b) have never resulted in an out-of-service order. The OOS rate for this code is 0.0%—all 249 all-time citations resulted in violations but kept trucks on the road.

This contrasts sharply with the all-FMCSR average OOS rate of 31.4%, and with peer violations in hazmat documentation. For comparison, 172.602(c)(1)—which covers maintenance and accessibility of the same emergency response information—also carries a 0.0% OOS rate across 1,464 citations.

172.602(b) is among the least serious hazmat citations. Our inspection database shows only 249 all-time citations for this code, ranking it #1157 of 3,036 FMCSR codes by enforcement volume.

Peer hazmat codes show vastly higher frequency and OOS rates: placarding violations (177.817(a)) appear 2,274 times with a 75.1% OOS rate, and general loading/unloading violations (177.834A-HMC) top 3,954 citations at 99.2% OOS. The 0.0% OOS rate for 172.602(b) indicates inspectors treat documentation form issues as compliance warnings rather than safety stops.

1. Obtain the citation details. Request the specific deficiency from the inspector or your safety manager—form issues can range from missing information to illegible placards.
2. Review your Emergency Response Information package. Check that all required documents are present, readable, and accessible in the required format.
3. Document the correction. Photograph or retain proof that you fixed the documentation issue.
4. Report to your carrier. This is a carrier-level hazmat compliance item; your fleet safety team needs to audit all vehicles for the same deficiency.
5. Consider a DataQs challenge if you believe the citation was issued in error or the deficiency was corrected before the inspection concluded.

This violation follows both. Under the CSA program, hazmat compliance deficiencies appear in your carrier's Safety Management BASIC and in your driver record under hazmat compliance. A single citation affects both the driver's profile (for future roadside inspections and employment background checks) and the carrier's FMCSA Safety Snapshots used for audits and enforcement targeting.

Even though you will not be placed out of service, the citation remains part of your permanent inspection history and your carrier's compliance data.

No active enforcement in the last 12 months. Our records show zero citations for 172.602(b) in the last 12 months and zero in the last 90 days, despite 249 all-time citations in the database.

This suggests either a shift in inspector focus toward more critical hazmat violations, or widespread carrier compliance with Emergency Response Information documentation standards. If your fleet operates hazmat vehicles, this dormant enforcement does not mean the requirement disappeared—it remains a regulatory obligation.

Greenwood Motor Lines Inc (USDOT 63391) leads with 6 citations, followed by Estes Express Lines (USDOT 121018) with 5. Fletes Internacionales de Coss SA de CV, Petrolificos de Monterrey, and Grupo Gasolinero y Automotriz de Tamaulipas each have 4 citations.

These patterns suggest the violations concentrate among carriers with larger hazmat operations and cross-border exposure. If you drive for a small fleet, the odds of encountering this citation are lower, but it remains a documentation compliance item during any hazmat inspection.

Freightliners (FRHT) account for 25 of the all-time citations, International trucks (INTL) for 18, and Peterbilts (PTRB) for 14. These represent the most common heavy-duty tractors in hazmat service, so the distribution reflects market share rather than a design or brand defect.

Your truck make does not determine risk—compliance depends on whether your Emergency Response Information package is complete, legible, and accessible as required by regulation.
