Direct answers grounded in TruckCodex inspection data
Yes—very likely. Across our 13 million inspection records, 74.1% of 393.126B citations result in an out-of-service order. This is far higher than the 31.4% average OOS rate across all FMCSR codes. In Texas, where this violation is most common, the OOS rate climbs to 71.9%. If an inspector finds unsecured flattened or crushed vehicles during your roadside check, expect your truck to be placed out of service until the cargo is properly secured.
A single 393.126B citation carries a CSA severity weight of 6 points. Your total points depend on how many violations occur within a 30-day window and your carrier's safety record at the time of the citation. Within 30 days, violations accumulate; beyond 30 days, older points age off the CSA BASIC category. Check your carrier's SMS (Safety Management System) portal or contact your fleet manager to see your current points total and how this citation affects your safety profile.
First, secure the cargo properly before you move the truck—your inspector will not clear you until it is. Second, check your truck for other mechanical issues: our data shows 393.126B citations often co-occur with lamp defects (4 shared inspections in the last 90 days), window obstructions (3 inspections), and brake issues (2 inspections). Have the inspector re-examine your vehicle once repairs are complete. Third, request a copy of the inspection report and keep it for your records or to submit through DataQs if you believe the citation is incorrect.
Yes. Our database shows 393.126B has a 74.1% out-of-service rate, well above the 31.4% national average across all codes. Among similar vehicle maintenance violations, only general maintenance/repair (396.3) exceeds it at 45.3% OOS rate. Most lighting and inspection violations result in 0–6.9% OOS rates. The high rate reflects FMCSA's strict enforcement: unsecured heavy cargo poses immediate road safety hazard, so inspectors nearly always ground the vehicle until the problem is fixed.
Yes. If you believe the citation was issued in error—for example, if the cargo was properly secured but the inspector misconstrued the securement method—you can submit a DataQs (Detailed Examination and Administrative Review) challenge within 15 days of the violation. Document your securement method with photos and the regulation citation (393.126B allows secured flattened/crushed vehicles under proper methods). Equipment-based violations like this one are contestable if you can prove compliance. Contact your carrier's safety director or a FMCSA-recognized third party to prepare the submission.
Texas dominates. Our records show 32 citations in Texas over the last 180 days (71.9% OOS rate), followed distantly by Illinois with 2 citations and Iowa with 1. The concentration in Texas likely reflects the volume of heavy haulage and intermodal operations in that state. If you operate in or through Texas, ensure your cargo securement procedures exceed minimum standards—inspectors there are writing this citation at higher frequency than the national average.
Immediate. You are out of service until fixed, and 74.1% of 393.126B citations result in OOS placement. Over the last 90 days, we recorded 16 citations—averaging 5.3 per month—with no downward trend. June, July, and September 2025 each saw 11–12 citations, showing persistent enforcement. Do not attempt to move the truck until cargo is re-secured to standard and the inspector has verified compliance. Delays cost you revenue and risk a second citation for operating OOS.
Both. FMCSA assigns vehicle maintenance violations to the carrier's BASIC score (Vehicle Maintenance and Cargo Securement BASICs). The citation appears on your carrier's SMS profile, affecting their safety rating, insurance, and audit scores. As the driver, it is reported under your Motor Carrier Safety Profile (if you are a lease operator) and your personal inspection history. Your carrier's safety manager must address the violation—driver retraining and maintenance protocols—to prevent future occurrences and improve the company's CSA standing.
