Form and manner of Emergency Response information
Direct answers grounded in TruckCodex inspection data
No. Across our inspection records, 172.602B has a 0.0% out-of-service rate—all 182 citations in our database resulted in warnings or fines, never an immediate OOS order. This is significantly better than the all-FMCSR average of 31.4%, making it one of the least severe hazmat documentation violations. You will not be removed from service, though you must correct the Emergency Response information issue before your next inspection.
Much less serious than most. Peer hazmat codes in our data show stark differences: general loading/unloading (177.834A-HMC) has a 99.2% OOS rate and 3,954 citations; placarding violations (177.817a) hit 75.1% OOS with 2,274 citations. By contrast, 172.602B's 0.0% OOS rate ranks it among the lowest-enforcement hazmat violations. It's a compliance fix, not an operational shutdown—similar to 172.602(c)(1), which also runs 0.0% OOS.
Citation volume is stable and low. Over the last 12 months, we recorded 92 citations nationally—an average of about 8 per month. December 2025 saw a spike to 14 citations, but recent months (February and March 2026) returned to 11 each. This is a rare violation: 172.602B ranks #1240 of 3,036 FMCSR codes by all-time enforcement volume, meaning most drivers and carriers never encounter it.
Texas dominates our data with 50 citations in the last 180 days, followed by Illinois with 5 and North Carolina with 1. The concentration in Texas likely reflects hazmat corridors and border zone operations, where Emergency Response documentation is scrutinized more heavily. If you operate in these states, ensure your paperwork exceeds minimum standards.
Both regulate Emergency Response information, but at different enforcement scales. 172.602(c)(1)—Maintenance and accessibility of Emergency Response information—has 1,464 all-time citations and a 0.0% OOS rate. 172.602B has only 182 citations and also 0.0% OOS. Both are treated as non-critical fixes. The distinction lies in the specific requirement cited; consult your violation notice for which subsection was cited and what correction is needed.
Yes, if there is a factual error in the inspection report. DataQs allows you to challenge roadside inspection records within 90 days. For a documentation violation like 172.602B, disputes succeed if you can show the information was actually present and correct at the time of inspection, or if the inspector misread the paperwork. Equipment violations are harder to contest; documentation issues hinge on what evidence you can produce. Submit your request through the FMCSA DataQs portal with photos and copies of your original documents.
It follows both. Under the CSA program, violations appear on the carrier's safety record (BASIC categories: Hazmat Compliance and Driver Fitness). Depending on who prepared or failed to maintain the Emergency Response information, the driver may also be flagged for a paperwork violation in audit files. The primary liability and corrective action typically rest with the carrier's hazmat compliance program. If you're an owner-operator, both your and your client's records may be affected.
