What 172.602(a) means in plain language
When you transport hazardous materials, you're required to carry emergency response information that's accurate, legible, and accessible to emergency responders in case of an incident. This regulation ensures that if your load spills, ignites, or creates a hazard, first responders and shippers have the data they need to act fast and safely.
A 172.602(a) citation means an inspector found your emergency response information incomplete—either missing entirely, partially filled out, or lacking required detail. This could mean the shipping papers didn't list all hazmat contents, emergency contact numbers weren't included, or the material's hazard class wasn't clearly documented. The regulation doesn't require you to create new documents; it requires you to ensure what you're carrying has complete emergency information attached.
What our enforcement data actually shows
Across our 13 million+ inspection records, 172.602(a) citations are uncommon. All-time we've recorded 515 citations for this violation, ranking it #904 out of 3,036 FMCSR codes by citation volume. More importantly: in the last 90 days, we've seen zero citations for this code. In the last 12 months, zero citations as well.
The out-of-service rate for 172.602(a) is 0.0%—no vehicle has ever been placed out of service for an incomplete emergency response record. This stands in sharp contrast to the all-FMCSR average OOS rate of 31.4%. The absence of OOS placements indicates that inspectors and carriers treat this violation as a documentation issue rather than an immediate safety hazard requiring vehicle removal.
Who gets cited most
Our inspection records show that since 2015, the carriers with the highest citation counts include Old Dominion Freight Line Inc (USDOT 90849) with 5 citations, Fuel South Express LLC (USDOT 362702) with 4 citations, and Petrolificos de Monterrey SA de CV (USDOT 3910464) with 4 citations. These numbers reflect the broad universe of hazmat carriers; no single fleet dominates the violation pattern. The data shows this violation affects carriers across all size classes and operational models.
Vehicle makes involved in 172.602(a) citations include Freightliner (37 citations), Ford (32 citations), and Kenworth (32 citations), reflecting the prevalence of these tractors in commercial hazmat service generally, not any defect or pattern specific to those manufacturers.
How severe is this compared to similar codes
In the hazardous materials category, 172.602(a) sits well below the enforcement intensity of related placarding and loading violations. Compare it to two peer codes:
177.834(a) (General loading/unloading hazmat) has 3,839 citations and a 97.9% OOS rate—meaning almost every cited vehicle was placed out of service. 177.817(a) (Placarding violation) shows 2,274 citations with a 75.1% OOS rate. Both of these affect the physical condition and visibility of hazmat loads.
172.602(c)(1) (Maintenance/accessibility of emergency response information) is the closest peer: it has 1,464 citations but also a 0.0% OOS rate, identical to 172.602(a). This suggests the entire 172.602 family of emergency information rules is treated as documentation-correctable rather than as grounds for immediate vehicle removal.
How to avoid it
Emergency response information is your responsibility before you ever roll up to a dock. Use these concrete steps:
-
Verify shipping papers are complete before loading. Before you accept a load, review every page of the bill of lading and hazmat paperwork. Confirm that every material listed on the manifest has a matching entry on the shipping papers, with proper hazard class, UN number, and emergency contact phone number. Don't assume the shipper filled it out correctly.
-
Keep emergency response information accessible in the cab. Store hazmat documentation in a clearly labeled folder within reach of the driver's seat, not buried under other paperwork or locked in a glove compartment. Inspectors and emergency responders need to retrieve it quickly.
-
Check for legibility. If shipping papers are faded, water-damaged, or handwritten in poor print, ask the shipper for a clean copy. Illegible emergency information is treated the same as incomplete information.
-
Confirm placards match cargo. As a final pre-trip check, verify that the placards on your vehicle match the hazmat materials listed on your shipping papers. This cross-check catches mismatches before you're cited.
-
Request shipper contact info if not provided. If the emergency contact field on the shipping papers is blank, call the shipper and have them add it before you depart. Don't leave blanks; assume an inspector will find them.
-
Take a photo of all hazmat paperwork before departure. Photograph the completed shipping papers and emergency information with the date and time visible. This creates a timestamped record that documents completeness at the moment you accepted the load, protecting you if a page is later disputed.
