Not automatically. Across our 13 million inspection records, 177.834B violations resulted in an out-of-service placement in 40.0% of cases—that's 2 out of 5 all-time citations. This is higher than the national average OOS rate of 31.4% across all FMCSR codes, so there's meaningful risk. Whether you're placed OOS depends on the specific circumstances of the violation and the inspector's assessment at roadside.
177.834B is relatively rare but moderately serious. Our data shows only 5 all-time citations—ranking #2406 of 3,036 FMCSR codes by volume. However, its peer violations in the same category vary widely: 177.834A-HMC hits a 99.2% OOS rate, while 172.502(a)(1) only reaches 18.5%. Your violation is in the middle, suggesting it's treated seriously but not as a hard stop as general loading/unloading hazmat violations.
Immediate steps: (1) Document the citation details and inspection report fully. (2) If your truck wasn't placed OOS on the spot, verify compliance before your next haul. (3) Review your shipping papers and hazmat procedures—our data shows 172.203C2 (missing RQ on shipping papers) co-occurred in recent 177.834B inspections. (4) If you believe the citation is factually wrong (e.g., misidentified vehicle or incorrect documentation), prepare evidence for a DataQs challenge within 90 days.
Very infrequently. Our inspection database shows 1 citation in the last 90 days, 4 in the last 12 months, and 5 all-time. The trend last 12 months shows 2 citations in July 2025, then 1 each in August 2025 and March 2026. This is not a high-enforcement violation nationally, so if you've received one, it's worth taking seriously as a rare finding.
Possibly. The DataQs request for reconsideration process allows drivers and carriers to challenge citations they believe are factually incorrect or not supported by evidence. Success depends on whether the violation is a documentation error (easier to contest) or an actual equipment or procedure failure (harder to overturn). You have 90 days from the inspection date to file. Gather the inspection report, photographs, and any maintenance or compliance records supporting your position.
In the last 180 days, our records show all enforcement concentrated in one state: Texas, with 1 citation and 0 out-of-service placements. With only 1 recent citation nationwide, this violation is not geographically concentrated—it's simply rare across the board.
Our all-time data shows 177.834B spread thinly: one citation each to Federal Express Corporation, GFS Transport LLC, Covenant Transport LLC, HP Carriers Inc, and Loess Enterprise LLC. Vehicle makes cited include GDAN (2 citations), and PTRB, RAM, Volvo, and WKM (1 each). No single carrier or make dominates the violation pattern, reflecting the rarity of this code.
If you've been cited, address it promptly. While only 1 citation occurred in the last 90 days, the 40.0% OOS rate means serious risk. Do not ignore the violation or assume it's minor. Review the specific deficiency noted in your inspection report, correct the documented issue, and document your corrective action. Future inspectors will check for the same violation, and a pattern strengthens enforcement liability.
