No. Across our 13 million inspection records, 393.24D has never resulted in an out-of-service placement—a 0.0% OOS rate across all 84 all-time citations. This violation is cited but does not trigger immediate roadside removal. Compare that to the 31.4% average OOS rate across all FMCSR codes: 393.24D is far less likely to ground your truck than most violations.
393.24D carries a severity weight of 3, which determines how heavily the violation factors into your Compliance, Safety, Accountability profile. The actual CSA points accrued depend on your 12-month violation history and the specific BASIC category. A single citation will affect your Unsafe Driving and Vehicle Maintenance BASICs over a rolling 12-month window.
First, verify the load marking and lighting. Our data shows 393.24D often appears alongside fuel system leaks (3 shared inspections in the last 90 days), brake defects (2 shared inspections), and tire issues (2 shared inspections). Inspect those systems next. Second, document your compliance—take photos of corrected load markings and lighting, keep repair receipts. Third, request the inspection report details to understand which specific load projections were cited.
Not in terms of enforcement severity. 393.24D ranks #1474 of 3,036 FMCSR codes by citation volume (84 all-time). Compare that to 393.9 (Inoperable Required Lamps), which has 660,737 citations and a 15.4% OOS rate. Or 393.11 (Lighting Devices/Reflectors), at 179,734 citations with 1.8% OOS. 393.24D is rarely cited and has zero out-of-service outcomes in our database.
Yes, you may contest through FMCSA's DataQs system if you believe the citation is inaccurate or the inspection was procedurally improper. 393.24D involves visual inspection of physical equipment (load marking and lighting), so contestability hinges on whether the inspector correctly verified compliance. Keep photos, measurements, and documentation of your load projections and lighting setup. Submit evidence within the DataQs window.
Texas leads by far. Over the last 180 days, our records show 20 citations in TX with a 0.0% OOS rate. This is the only state in our top-enforcement list for 393.24D. The overall low citation volume (38 citations in the last 12 months nationwide) suggests enforcement is geographically sparse—so if you operate primarily in other regions, the risk is lower.
Moderately urgent from a compliance standpoint, though not a roadside emergency. Our 90-day trend shows 6 citations (down from 8 in August and 6 in November 2025), indicating steady but not spiking enforcement. The violation does add CSA points and counts on your record, so correct your load marking and lighting within days, not weeks. Document the fix immediately to demonstrate good faith if audited.
393.24D is primarily a carrier and vehicle maintenance responsibility. The violation records on the carrier's USDOT profile and affects fleet safety metrics. However, the driver operating the vehicle is also accountable—unsafe load projection and lighting failures can result in driver-level CSA entries if the carrier's maintenance practices are implicated. Both the carrier safety profile and the driver's record may be impacted depending on investigation scope.
