What 172.602(c) means in plain language
172.602(c) requires drivers and carriers transporting hazardous materials to maintain and keep accessible emergency response information during transport. This information—typically found in shipping papers, emergency response guides, or placards—must be available for quick reference if an incident occurs.
The regulation exists so that first responders, shippers, and drivers themselves can instantly access critical safety data: what chemical is being transported, what hazards it poses, and what immediate actions protect life and property. If an inspector finds that you cannot quickly produce this information or that it is not properly maintained (damaged, outdated, or improperly stored), you will be cited.
This is distinct from simply having the information somewhere in your vehicle—it must be organized and accessible in the way the regulations expect.
What our enforcement data actually shows
Across our 13 million roadside inspection records, 172.602(c) has generated 101 all-time citations. In the last 12 months, we recorded zero citations for this code, and zero in the last 90 days. This code ranks 1,420th out of 3,036 FMCSR codes by total citation volume.
Most importantly: 101 out of 101 citations did not result in an out-of-service order. The 0.0% out-of-service rate for 172.602(c) contrasts sharply with the all-FMCSR average of 31.4%. This tells you that inspectors rarely view 172.602(c) violations as immediately safety-critical enough to halt operations, though the citation itself still creates a compliance record and potential fine.
The near-zero recent enforcement suggests either strong compliance industrywide or that inspectors are focusing inspection attention on higher-risk hazmat codes.
Who gets cited most
Our inspection records do not show a clear geographic concentration for 172.602(c) citations. The violation appears distributed across carrier operations nationwide, with six carriers tied for the highest citation count: Saskatchewan Ltd (USDOT 3096777), AAA Cooper Transportation (USDOT 92261), Basin Western Inc (USDOT 167011), Orca Pacific Inc (USDOT 1563937), J B Hunt Transport Inc (USDOT 80806), and Tax Airfreight Inc (USDOT 153935), each with 2 citations over the entire database period.
The distribution across top carriers suggests this is not a systematic failure at any single fleet but rather isolated compliance gaps across the industry. Vehicle-wise, Freightliner units account for 45 of the 101 citations (44.6%), followed distantly by Kenworth with 19. This likely reflects the prevalence of Freightliner tractors in the general trucking population rather than a defect in how Freightliners are equipped.
How severe is this compared to similar codes
Other hazardous materials codes in the Federal Motor Carrier Safety Regulations show vastly different enforcement intensity and consequences. For context:
- 177.834(a) (General loading and unloading of hazmat) has generated 3,839 citations with a 97.9% out-of-service rate—a critical safety violation that almost always stops the vehicle.
- 177.817(a) (Placarding violations) has 2,274 citations with a 75.1% out-of-service rate.
- 172.602(c)(1) (Maintenance and accessibility of emergency response information), the closely related subsection, has 1,464 citations but maintains a 0.0% out-of-service rate, identical to your code.
172.602(c)'s 0.0% OOS rate mirrors 172.602(c)(1), suggesting inspectors treat emergency response information issues as administrative or documentational rather than immediate threats to safety. By contrast, the loading/unloading and placarding violations are treated as hazardous-condition enforcement.
How to avoid it
Emergency response information is straightforward to maintain once you establish the habit:
- Before each trip, verify that your shipping papers are present, legible, and organized. Do not allow documents to become creased, water-damaged, or faded. If a placard or label is deteriorating, replace it.
- Keep the Emergency Response Guidebook (ERG) or equivalent reference guide in the cab, within immediate reach. It should not be buried under seat cushions or stored in a locked compartment. An inspector or first responder must be able to access it without delay.
- During your walk-around inspection, check that all placards are firmly attached, facing outward, and readable from at least 30 feet away. A placard that has peeled, faded, or become obscured does not meet the accessibility requirement.
- If you are cross-docking or transferring hazmat, ensure the shipping papers transfer with the load and that you have confirmed all information is accurate and current. Gaps between vehicles or carriers are where emergency response information gets lost.
- Store emergency response materials in a designated, weatherproof location in your cab. Do not use them as shop rags or let them get crumpled in a door pocket.
- On longer loads, periodically confirm that papers remain legible and placards remain secure. Vibration and weather can loosen adhesive or fade ink.
The pattern in our data—only 101 citations over the entire history of the database and zero in the past year—suggests that simple diligence with documentation and placard condition is sufficient to avoid this violation.
