What 171.2(e) means in plain language
171.2(e) addresses requirements related to hazardous materials documentation and carrier compliance. The regulation establishes that operators and carriers must maintain proper records and follow specific procedures when transporting hazardous commodities. This includes ensuring that all required paperwork, placards, and operational protocols are in place before the vehicle leaves the facility.
A citation for this code typically indicates that an inspector found a documentation gap, missing record, or procedural discrepancy during a roadside inspection. This is not necessarily a safety-critical defect—it's an administrative or record-keeping issue that affects compliance with hazmat transportation rules.
What our enforcement data actually shows
Across our database of 13 million+ inspections, 171.2(e) has generated only 1 citation all-time, with 0 citations in the last 12 months and 0 in the last 90 days. This makes 171.2(e) ranked #2796 out of 3,036 FMCSR codes by citation volume.
Of that single citation on record, the vehicle was not placed out of service, giving this code a 0.0% OOS rate. For context, the all-FMCSR average OOS rate is 31.4%, meaning 171.2(e) violations are far less likely to result in immediate vehicle removal than the typical FMCSR violation.
The scarcity of citations for this code suggests either that most carriers maintain strong compliance, or that inspectors encounter the violation infrequently during roadside stops. Either way, if you've been cited for 171.2(e), you're statistically in rare company.
Who gets cited most
Our inspection records show that C & S CARRIERS INC (USDOT 1341623) accounts for 1 citation under this code. With such minimal citation history in the database, geographic patterns and carrier comparisons are not meaningful. The single citation does not indicate a systemic issue with any particular carrier or region.
How severe is this compared to similar codes
When we look at peer codes in the same regulatory category, 171.2(e) sits well below most of its comparables in enforcement volume. For example:
- 376.11(d)(1) has generated 6,383 citations with a 0.0% OOS rate—dramatically higher citation volume but the same out-of-service outcome.
- 999 shows 4,802 citations with a 12.1% OOS rate, indicating that some violations in this family are more likely to result in vehicle removal.
- 107.620(b) accounts for 2,120 citations with a 0.2% OOS rate, still roughly 2,000 times more frequently cited than 171.2(e).
The low citation count for 171.2(e) relative to these peer codes suggests that either the violation is harder to trigger during inspections, or that compliance in this specific area is particularly strong across the industry.
How to avoid it
Because 171.2(e) centers on hazmat documentation and procedural compliance, here are concrete actions you can take:
-
Before every trip carrying hazmat, verify your paperwork. Check that all required shipping papers are present, legible, and match your cargo manifest. Don't leave the dock without them.
-
Confirm placards and labels. Ensure that hazmat placards on all four sides of the vehicle are correct, visible, and securely attached. A missing or incorrect placard can trigger documentation-related citations.
-
Review your hazmat training certificate. Keep it current and accessible. Inspectors often ask to see proof of training when they suspect documentation gaps.
-
Know what's in your tank or trailer. If you cannot accurately describe the commodity you're transporting, your paperwork is suspect. Verify the product name, UN number, and hazard class before departure.
-
Carry copies of required permits and certifications. Some hazmat loads require special permits or carrier certifications. Have them in the cab, not just at the office.
-
Use a pre-trip checklist specific to hazmat. If your fleet doesn't provide one, ask for it or create one that includes a documentation review step before you hit the road.
Because this code is so rarely cited, the violation is likely to be caught during a formal hazmat inspection rather than a routine roadside check. The best defense is treating hazmat paperwork with the same rigor you'd apply to vehicle maintenance.
