No. Across our inspection records, 172.332B citations result in a 0.0% out-of-service rate—meaning not a single truck has been placed OOS for this violation. All 20 all-time citations in our database resulted in the truck remaining in-service. This is substantially below the 31.4% all-FMCSR average OOS rate, making this one of the less severe hazmat violations you can receive.
This citation carries a CSA severity weight of 4 points. The actual points added to your Safety and Fitness Electronic Records (SAFER) profile depends on when the violation was recorded and the 30-day rolling violation multiplier system—violations in the same category within 30 days compound the impact. Contact your carrier's compliance team for your specific BASIC category assignment, as hazmat violations typically fall under the Hazmat Compliance BASIC.
Not compared to more serious placarding violations. Our data shows 177.834A (general loading/unloading hazmat) has a 99.2% OOS rate and 177.817(a) (placarding violation) has a 75.1% OOS rate. By contrast, 172.332B's 0.0% OOS rate and peer code 172.516(c)(6) (placard damaged/deteriorated) at 1.6% OOS puts this among the lowest-severity hazmat infractions. However, it still signals documentation or equipment compliance gaps that warrant immediate correction.
Rarely. Across 13 million inspections, we see only 20 all-time citations for 172.332B, ranking it #1938 out of 3,036 FMCSR codes by volume. In the last 12 months, just 2 citations were issued, and none in the last 90 days. This low frequency means inspectors are not routinely flagging missing identification numbers—but when they do, it's a clear documentation miss that's worth fixing immediately.
Contest eligibility depends on the facts. If the inspection report shows a photo of a clearly visible and accurate class/division identification number on your placard, you have strong grounds to challenge the citation through FMCSA's DataQs (Roadside Data Quality System) portal or your carrier's safety team. If the identification number was genuinely missing or illegible, correction is faster than appeals—replace the placard and move forward. Consult your carrier's compliance department for the best path in your case.
Bennett Motor Express LLC (USDOT 92693) leads with 5 citations for this violation. Navarro and Sons (USDOT 2762967) follows with 3 citations. The remaining citations are scattered among single-incident carriers. These numbers underscore that this violation is sporadic across the industry—no carrier shows a pattern of systemic 172.332B non-compliance in our records.
Moderately urgent. While the 0.0% OOS rate means you won't be pulled off the road, the citation still adds 4 CSA points and signals a documentation or equipment lapse. With only 2 citations in the last 12 months, this isn't a high-frequency problem—but any hazmat placard defect should be corrected before your next load. Replace or repair the placard immediately and verify all future shipments have clear, legible class and division identification numbers.
