Direct answers grounded in TruckCodex inspection data
No. Across our inspection database, the 0.0% out-of-service rate for 177.802 means every citation issued resulted in a non-OOS finding. This is significantly lower than the 31.4% all-FMCSR average OOS rate, and far below peer hazmat placarding violations like 177.817(a) at 75.1% OOS or 177.834A-HMC at 99.2% OOS. Your truck stays in service, but the violation still counts against your record.
Not compared to other hazmat violations. Our records show only 2 all-time citations for 177.802 nationally, ranking it #2651 out of 3,036 FMCSR codes. In the same hazmat category, 177.834A-HMC has 3,954 citations and 177.817(a) has 2,274 citations. The rarity of 177.802 enforcement and its 0.0% OOS rate indicate it is low-severity relative to core hazmat loading, unloading, and placarding violations.
First, review the citation document carefully—note the specific deficiency and date. Second, photograph the condition or equipment cited so you have your own evidence. Third, contact your fleet safety manager or DOT compliance officer immediately to confirm whether the finding was an inspection error or a legitimate gap. Fourth, if the citation appears incorrect, file a DataQs (FMCSA Safety Management System) challenge within 30 days of the inspection. Fifth, obtain any repairs or corrective documentation if a legitimate issue exists. Since no OOS was issued, you retain full operation while contesting if needed.
Rarely. Our database records only 2 citations all-time for 177.802 and 0 citations in the last 12 months and last 90 days. This extremely low volume means inspectors encounter this violation almost never, making it one of the least-cited FMCSR codes. For context, the same hazmat category includes 177.834A-HMC with 3,954 citations—nearly 2,000 times more frequent.
Our records show two carriers with 177.802 citations: WILLIAMS IGNACIO NARCIA LEON (USDOT 3089559) with 1 citation and CAPITOL HELICOPTERS (USDOT 3295662) with 1 citation. Given the rarity of this violation across 13 million inspections, these represent the only instances in our database. Neither carrier shows a pattern of repeated 177.802 violations.
Yes. If the citation is factually incorrect—for example, if the inspector misidentified equipment, misread a label, or recorded the wrong vehicle—you can challenge it through the FMCSA's DataQs (Safety Management System data query) process within 30 days of the inspection. Gather all documentation supporting your position: photos, maintenance records, inspection reports, or manufacturer specs. The DataQs process is designed for errors in objective findings; provide clear evidence that contradicts the citation.
177.802 ranks as significantly lower-severity than related hazmat violations. Peer codes in the hazmat category show dramatically different patterns: 177.834A-HMC (general hazmat loading/unloading) has 3,954 citations and 99.2% OOS rate, while 177.817(a) (placarding violation) has 2,274 citations and 75.1% OOS rate. By contrast, 177.802's 0.0% OOS rate and 2 all-time citations indicate inspectors rarely cite this code, and when they do, it does not result in vehicle removal from service.
No. 177.802 is not OOS-eligible under FMCSR regulations, meaning even if cited, it cannot trigger an out-of-service order. This aligns with our data: all 2 citations in our database resulted in non-OOS findings. If you are cited for this code alone, your truck remains legally operable and you can continue driving while addressing the citation through DataQs or compliance correction.
