Immediate steps: (1) Document the current condition of your reflective sheeting with photos. (2) Schedule a mechanic appointment to inspect and repair retroreflective material on your pre-1993 vehicle. (3) Check for related violations—our data shows 393.13B often appears alongside fuel system leaks (396.5B), defective lamps (393.9), and windshield issues (393.78) in the same inspections.

Texas leads by far: 21 citations in the last 180 days with a 0.0% OOS rate. Illinois follows with 2 citations, and Iowa with 1. The geographic concentration in Texas suggests that older vehicles or certain equipment types operating in that region face heightened scrutiny. Freightliner units account for 33 of the 102 all-time citations for this code.
Citations have been variable month-to-month over the last 12 months. August 2025 saw the highest volume with 14 citations, while recent months (January–March 2026) averaged 3–6 citations per month. The 68 citations in the last 12 months represent a steady enforcement presence, though not spiking. The enforcement remains active but remains among the rarer FMCSR violations overall.
Yes, you can file a DataQs (FMCSA Safety Management System challenge) to contest the citation if you believe it was recorded in error. Since this is an equipment-based violation involving the physical condition of reflective material, your challenge should include photographic evidence taken before and after the inspection, maintenance records, or documentation that the vehicle does not fall under the pre-1993 manufacturing date requirement. FMCSA reviews these disputes within 30 days.
Our all-time data shows that 4KX Transportation Inc (USDOT 2818406), Aggregate Haulers ILP (USDOT 1021485), RKR Hauling LLC (USDOT 3495728), and K1K Trans LLC (USDOT 4282391) each have 2 citations. Most other carriers in our database have only 1 citation for this code. This distribution suggests the violation is spread across many carriers rather than concentrated among repeat offenders.
