Direct answers grounded in TruckCodex inspection data
No. Across our inspection records, 172.302C has never resulted in an out-of-service citation—the OOS rate is 0.0%. All 1 citation in our database was issued without placing the vehicle out of service. This is significantly lower than the 31.4% average OOS rate across all FMCSR codes, and far below hazmat-related violations like general loading/unloading violations (99.2% OOS rate) or placarding failures (75.1% OOS rate).
Not compared to other hazmat violations. While 172.302C falls in the Hazardous Materials category, our inspection records show it ranks #2796 out of 3,036 FMCSR codes by citation volume. Peer violations in the same category are cited far more frequently—for example, general loading/unloading hazmat violations have 3,954 citations with 99.2% OOS rates, while 172.302C has only 1 all-time citation. The lack of enforcement volume and zero OOS history suggests this is a lower-priority finding.
Zero times in the last 12 months, and zero times in the last 90 days. Our database of 13 million+ roadside inspections shows only 1 citation for 172.302C in all-time records. This extremely low enforcement volume means you are unlikely to encounter this violation in routine operations.
Immediate steps:
Because this violation is documentation-based rather than equipment-based, it is typically contestable if you can produce the valid permit number.
Yes. 172.302C is a documentation and compliance finding, which means it is contestable through the FMCSA's DataQs RDR (Roadside Data Record) process. If you have the correct special permit number and can show it was valid at the time of inspection, you can file a challenge with the FMCSA within 90 days of the citation. DataQs allows you to dispute factual errors or provide corrected documentation. Success rates depend on whether you can produce the permit—this is a recordkeeping issue, not a structural or safety defect.
HOBBS RENTAL LLC (USDOT 2053622) is the only carrier in our records with a 172.302C citation, with 1 citation all-time. Given the extremely low citation volume across the industry for this code, this finding is statistically rare and should not be treated as a pattern or systemic issue.
172.302C is far less serious than related hazmat violations. Our data shows:
172.302C is cited far less frequently and has never resulted in an out-of-service placement, suggesting inspectors view it as a documentation deficiency rather than a direct safety hazard.
Trending down to inactive. Our records show 0 citations in the last 12 months and 0 in the last 90 days, after 1 all-time citation. This indicates 172.302C is not a focus area for roadside enforcement. You are unlikely to be cited for this violation in current inspection operations.
