No. Across our inspection records, 177.848(f) has never resulted in an out-of-service placement—the OOS rate is 0.0%. This is significantly lower than the all-FMCSR average of 31.4%. The violation is not OOS-eligible under FMCSA enforcement authority. However, your carrier may impose additional internal requirements depending on the specific nature of the finding.
Much less severe than related hazmat citations. Our database shows peer hazmat violations carry dramatically higher OOS rates: general loading/unloading violations (177.834A-HMC) hit 99.2% OOS rate with 3,954 citations, and placarding violations (177.817(a)) reach 75.1% OOS rate across 2,274 citations. By contrast, 177.848(f) has only 1 citation all-time with 0% OOS rate, making it one of the rarest hazmat enforcement issues we track.
Yes, you can submit a DataQs (Roadside Data Quality) dispute if you believe the citation was issued in error or based on incorrect facts. DataQs allows drivers and carriers to challenge inspection findings directly to FMCSA. The strength of a successful challenge depends on whether the finding was based on documented evidence (harder to contest) or inspector observation (more contestable). You'll need the specific inspection report number and clear documentation showing why the citation was incorrect.
Extremely rarely. Across our 13 million+ inspection records, 177.848(f) has generated only 1 citation all-time, with 0 citations in the last 12 months and 0 in the last 90 days. This ranks the code at #2796 out of 3,036 FMCSR violations by enforcement volume. If you've received this citation, you're in a very small group—indicating either a highly unusual cargo situation or a specific compliance gap inspectors rarely encounter.
Both. Under FMCSA Safety Management Cycles, hazmat violations are recorded in CSA BASICs that apply to both the driver and the carrier. The citation stays on your Motor Carrier Safety Insp & Comp record and the company's Safety Management record. Your carrier is responsible for ensuring corrective action, but the violation reflects on both parties. This is why even low-severity hazmat citations require carrier follow-up—they affect fleet safety ratings and insurance costs.
Green Sunrise B Inc (USDOT 3903336) received the single 177.848(f) citation in our records. This represents the only enforcement action for this code across 13 million inspections, underscoring how uncommon this violation is in roadside enforcement. If you drive for a different carrier, the citation pattern suggests this is not a systematic industry problem.
