Direct answers grounded in TruckCodex inspection data
No. This citation will not place your truck out of service. Across our inspection database, 393.13D1-CSSRR has a 0.0% out-of-service rate—all 176 all-time citations resulted in warnings or citations only, with zero vehicles removed from service. This is significantly lower than the 31.4% average out-of-service rate across all FMCSR codes, making this one of the least severe equipment violations you can receive.
First, document the reflector condition with photos. Second, review the truck for any additional violations—our inspection records show this code commonly co-occurs with inoperable lamps (7 shared inspections in the last 90 days) and driver fatigue citations (8 shared inspections). Third, schedule a repair at a qualified shop and keep all receipts. Finally, file the citation away; you'll need proof of correction if audited. Since no out-of-service order is issued, you can continue operating while you arrange the fix.
No, it's relatively minor. The 0.0% out-of-service rate for 393.13D1-CSSRR contrasts sharply with peer codes: inoperable lamps (393.9) have a 15.4% OOS rate and 660,737 citations; brake defects (393.47E) have 180,363 citations; and general inspection failures (396.3) carry a 45.3% OOS rate. Reflector inadequacy is a visibility and compliance issue, not a safety-critical failure like brakes or lighting.
California leads by far, with 17 citations in the last 180 days (0.0% OOS rate). Florida follows with 4 citations, and Arizona and Utah (US) each have 3. Outside these top states, citations are rare—most states have logged 0–2 in the same period. If you operate primarily in the Midwest or Northeast, you're less likely to encounter this violation.
Repair should happen within 30 days to avoid repeat citations and potential compliance escalation. Our monthly data shows citation activity fluctuates—November 2025 had 13 citations and July 2025 had 12, suggesting seasonal or regional enforcement intensity. While no immediate out-of-service order applies, operating a pre-1993 trailer with inadequate reflectors exposes you to repeat stops. Schedule the repair promptly and retain documentation.
Yes, you can file a DataQs (Safety Management System challenge) request, though success depends on the evidence. If the inspector's measurement or documentation was inaccurate—for example, if reflectors met spec but were recorded as inadequate—you have grounds. If the reflectors genuinely did not meet conspicuity standards for your trailer's manufacture date, the citation will likely stand. Gather photos, maintenance records, and repair invoices before filing. Most disputes are resolved within 30–60 days.
In the last 90 days, 23 total 393.13D1-CSSRR citations were issued. Most appeared alongside other defects: 8 inspections also cited inoperable required lamps (393.9A), 7 cited driver fatigue (392.2), 4 cited emergency warning devices missing (393.95F), and 3 cited coupling defects (393.55E-B). This pattern suggests inspectors conduct thorough vehicle checks when they spot reflector problems, so request a full pre-trip inspection to identify and fix any co-occurring issues before your next roadside stop.
Freightliner and Freightliner Heavy Trucks (combined 48 citations) dominate the all-time citation list, followed by Peterbilt (13) and Kenworth (11). This reflects the prevalence of these makes in the trucking fleet rather than a design defect. The citations are spread across many carriers—no single carrier has more than 3—suggesting this is an isolated maintenance issue rather than a fleet-wide problem with any manufacturer.
