Questions & Answers

Direct answers grounded in TruckCodex inspection data

Will 178.341-1 put my truck out of service?

No. Across our inspection database, the 0.0% out-of-service rate for 178.341-1 shows this violation does not result in OOS placement. Of the 1 all-time citation on record, zero trucks were removed from service. Compare this to the all-FMCSR average OOS rate of 31.4%—this code sits well below that threshold and is not OOS-eligible under FMCSA rules.

How serious is a 178.341-1 citation compared to other hazmat violations?

178.341-1 is far less severe than most hazmat codes. Similar hazmat violations in the same category show 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. The 0.0% rate for 178.341-1 makes it one of the lowest-risk hazmat citations you can receive.

What do I do right after getting cited for 178.341-1?

Immediate steps:

  1. Document the citation details (date, time, inspector name, vehicle VIN)
  2. Photograph the equipment or load state referenced in the violation
  3. Keep all paperwork from the roadside inspection
  4. Report the citation to your dispatcher and safety manager
  5. Review your hazmat compliance procedures with your carrier
  6. Preserve records for potential DataQs contest within 90 days if you believe the citation was inaccurate

Is 178.341-1 cited often, or is this rare?

This is extremely rare. Our database shows just 1 citation all-time for 178.341-1, with zero citations in the last 12 months and zero in the last 90 days. Nationally, 178.341-1 ranks #2796 out of 3,036 FMCSR codes by citation volume. You are far more likely to see enforcement on other hazmat violations than this specific code.

Can I fight a 178.341-1 citation through DataQs?

Yes. FMCSA allows drivers and carriers to contest roadside inspection findings through the DataQs RDR (Roadside Dispute Resolution) process within 90 days of citation. You can challenge the citation if the inspector's documentation was incomplete, if equipment was actually in compliance, or if the violation was misidentified. Submit evidence (photos, maintenance records, weight tickets) to support your dispute through the FMCSA's DataQs portal.

Which carriers and states see 178.341-1 most often?

Our data covers all-time enforcement: Coastal Carriers of Connecticut LLC (USDOT 1271367) has 1 citation on record. The vehicles cited include a Freightliner and a Heil Co. unit. The extremely low citation volume means state-by-state breakdown is not meaningful—this violation simply does not appear frequently in the 13 million+ inspection records in our database.

How urgent is it to fix what was cited under 178.341-1?

Low urgency from an enforcement perspective. With zero OOS placements across all citations and zero citations in the last 90 days, the immediate threat of removal is nonexistent. However, hazmat compliance is always mandatory. Review the specific deficiency noted by the inspector and correct it to stay within DOT regulations. The lack of recent enforcement activity suggests this is not a high-priority inspection focus.
