FMCSR 171.2F: Hazardous Materials Violations Q&A

No. Across our 13 million inspection records, 171.2F citations have resulted in zero out-of-service placements out of 3 total citations all-time, for a 0.0% OOS rate. This code is not designated as OOS-eligible under FMCSA rules. Compare this to the national average OOS rate of 31.4% across all FMCSR codes—171.2F sits well below that threshold, meaning inspectors are citing it as a compliance notice rather than a roadside violation grounds for immediate vehicle impounding.

A 171.2F citation means you transported hazardous materials in a way that didn't comply with DOT regulations. Our data shows this violation often appears alongside other hazmat issues: emergency response information violations, placarding problems, and CDL endorsement gaps. Immediately after citation: (1) document the specific violation on your citation; (2) verify you hold a valid hazmat endorsement on your CDL; (3) review the cargo and packaging against DOT shipping papers; (4) contact your carrier's compliance officer; (5) correct the deficiency before your next hazmat load.

171.2F ranks #2551 of 3,036 FMCSR codes by citation volume, meaning it's one of the least-cited violations nationwide. In the past 12 months, our records show only 2 citations. However, severity depends on context. The peer code 171.2K (representing a vehicle as carrying hazmat when it isn't) has been cited 255 times with a 1.6% OOS rate. Another variant, 171.2F-HMGRMC, shows 55 citations with a 3.6% OOS rate. Your specific violation's rarity suggests targeted enforcement or a serious packaging/transport method issue rather than systemic hazmat problems.

In the last 180 days, our inspection database recorded 171.2F citations almost exclusively in Iowa, with 2 citations and 0 out-of-service placements. Iowa represented the primary state for this violation during that period. Given the low national citation volume (only 1 citation in the last 90 days), enforcement is sporadic. If you operate hazmat routes through Iowa or similar agricultural/industrial corridors, pay close attention to DOT packaging and labeling compliance at pre-trip and post-load inspections.

When 171.2F appears, our data shows it frequently co-occurs with placarding violations (177.817A) and emergency response information gaps (172.600C). In the last 90 days, we also documented cases paired with operating a CMV without a hazmat CDL endorsement (383.23A2-H) and driver fatigue (392.2). These patterns suggest 171.2F often signals broader hazmat training or documentation deficiencies. If cited for 171.2F, immediately verify: (1) all placards are correct; (2) emergency response phone numbers are on the shipping papers and accessible; (3) your CDL endorsement is valid and current.

Very rare. Across our 13 million roadside inspection records, only 3 171.2F citations appear all-time, with just 2 in the last 12 months and 1 in the last 90 days. This makes 171.2F one of the least-enforced hazmat violations in the FMCSR code set. The carriers cited—Kuhnle Brothers Inc, Kris B Services Inc, and UG Transportation LLC—each received only 1 citation. This rarity suggests the violation requires egregious non-compliance or a specific audit trigger rather than routine roadside catching.

Yes, you can initiate a DataQs (FMCSA's Corrective Action Request) challenge through the official Safety Management System. However, contestability depends on the violation type. If the citation is based on documentation (missing paperwork, incomplete records), you may dispute it by submitting correct documents or clarifying the record. If it's based on equipment or cargo inspection findings, you'll need to prove compliance post-citation (photos, re-inspection, shipper documentation). Begin the process within 30 days of the citation for fastest resolution. Your carrier's safety manager should file on your behalf.

Both. Under FMCSA's Safety Management System, hazmat violations like 171.2F roll into the carrier's Safety Performance History (SPH) and contribute to the carrier's hazmat BASIC score. Your individual driver record also reflects the citation in DOCKET databases used by future employers and insurance underwriters. The violation does not expire, though its weight in enforcement algorithms decreases over time as you accumulate a longer clean record. If you drive for multiple carriers, each carrier's hazmat BASIC will reflect this citation during background checks and CSA audits.
