Direct answers grounded in TruckCodex inspection data
No. Across our 13 million inspection records, 172.600(c) citations result in an out-of-service placement only 0.4% of the time—just 4 instances out of 941 all-time citations. This is far below the 31.4% national average OOS rate across all FMCSR codes. You will almost certainly remain in-service after this citation, though you must immediately address the underlying compliance issue.
This violation carries a CSA severity weight of 6 points. The actual 30-day impact depends on how many other violations occur in that window, but this single citation will add 6 points to your safety score. It's a moderate-severity hazmat documentation violation, not a critical issue, but it does count toward your CSA Basic categories for hazardous materials compliance.
It's on the lower end of hazmat severity. Our data shows similar hazmat codes vary wildly: general loading/unloading violations (177.834) hit 97.9–99.2% OOS rates, while placard-deterioration violations (172.516(c)(6)) hit only 1.6%. At 0.4% OOS, 172.600(c) is one of the least-enforced hazmat documentation codes—only 941 citations all-time, ranking #733 out of 3,036 total FMCSR codes. But non-compliance is still a violation; treat it urgently.
Yes, DataQs allows you to challenge any roadside inspection record within 30 days. For 172.600(c), the most common grounds are: (1) emergency response information was actually accessible and the inspector missed it, or (2) you were not transporting hazardous materials when cited. File through the FMCSA DataQs portal with photo evidence or supporting documents. Documentation-based violations like this one are often contestable if you can prove the information was in the vehicle.
Zero citations in the last 12 months—and none in the last 90 days either. Across our 13 million inspection records, all 941 citations for this code occurred prior to the last year, indicating very low current enforcement activity. This is a rare citation in modern roadside inspections, but the requirement itself remains active and enforceable.
Estes Express Lines leads with 6 citations, followed by Saia Motor Freight Line LLC and Transportes Refrigerados GC Xpress SA de CV, each with 5 citations. Auto Tanques Rago SA de CV and Harold A Puryear Trucking Co Inc each have 4. Most carriers cited have only 3–6 total incidents, suggesting this is a sporadic finding rather than a systemic fleet issue. If you drive for one of these carriers, ask your safety team to review emergency response documentation procedures.
Freightliners (FRHT) account for 75 citations, Kenworths (KW) for 53, and Peterbilts (PTRB) for 40—the three most common makes cited. These dominate because they're the most common tractor models in hazmat service overall. No single truck type is inherently more prone to this violation; instead, the finding correlates with hazmat transportation frequency rather than equipment type.
