Direct answers grounded in TruckCodex inspection data
No. Across our inspection records, 178.703 has never resulted in an out-of-service order—the OOS rate is 0.0%, which is significantly lower than the 31.4% all-FMCSR average. All 8 citations in our database were issued without placing the vehicle out of service. This code is marked as not OOS-eligible, meaning inspectors cannot remove your truck from operation for this violation alone.
178.703 is among the least-cited and least-severe hazmat violations. Our records show only 8 all-time citations, ranking it #2269 of 3,036 FMCSR codes. Compare this to peer codes in hazmat: general loading/unloading violations (177.834A) have 3,954 citations with a 99.2% OOS rate, and placarding violations (177.817a) reach 2,274 citations at 75.1% OOS. The marking requirement for IBC containers generates a fraction of the enforcement volume.
Immediate steps:
Since this is not an OOS violation, you retain operational authority while resolving it.
In the last 180 days, citations appear in two states: Arizona (1 citation, 0% OOS rate) and Colorado (1 citation, 0% OOS rate). Enforcement is infrequent nationwide. Our full all-time database shows only 8 total citations across all states, indicating this is a low-volume finding regardless of geography.
No. Across the last 12 months, our records show only 3 citations for 178.703. In the last 90 days, there was 1 citation. This indicates enforcement is stable and sparse. Monthly data shows sporadic citations (one in June 2025, one in November 2025, one in March 2026), with no trend toward increased scrutiny.
Yes, you can contest any FMCSR citation through the DataQs program (FMCSA's online RDR dispute system). For a marking violation, your contest should focus on: (1) whether the marking was actually absent or illegible at the time of inspection, (2) photographic evidence of current compliance, or (3) documentation that marking was applied per regulation. Upload supporting evidence directly to your DataQs account. Success depends on the strength of your documentation against the inspector's observations.
Our inspection records show Imperative Chemical Partners Inc (USDOT 1796904) has 2 citations for 178.703. Five other carriers each have 1 citation: FNF Construction Inc, Superior Express Incorporated, KMS Express Inc, Rutco Transport LLC, and Mode Transport Ltd. No single carrier dominates enforcement, suggesting this is distributed across the hazmat carrier base.
Moderately urgent, but not emergency-level. Since the 0.0% OOS rate means you won't be pulled out of service, you have operational time to correct the marking. However, a citation creates a safety record and potential CSA scoring. Best practice: fix markings on all IBC containers within 24–48 hours and request re-inspection to close the citation quickly. The low volume of recent citations (1 in 90 days) suggests routine enforcement, not a regional crackdown.
