No. Across our 13 million inspection records, only 1 out of 176 all-time citations for 393.86A2 resulted in an out-of-service placement—a 0.6% OOS rate. This is far below the 31.4% national average across all FMCSR codes. A missing or defective ICC bumper is a violation, but inspectors almost never remove your truck from service for it. You'll get cited, but you can typically drive to a repair facility or dispatch location to fix it.
This violation carries a CSA severity weight of 5 points. The actual point total in your BASIC category depends on how many violations you accumulate in a 30-day rolling window. One 393.86A2 citation by itself adds 5 points; multiple violations in 30 days stack. The CSA points system is used by insurers and brokers to evaluate your safety profile, so even a single citation can affect your hireability and rates. Review your FMCSA Safety and Fitness Electronic Records (SAFER) portal to see your current totals.
It's on the lower end of severity. The 0.6% OOS rate for 393.86A2 is well below peer codes: Inoperable Required Lamps (393.9) hit 6.9% OOS, Lighting Devices (393.11) reach 1.8% OOS, and general Inspection/Repair/Maintenance violations (396.3) spike to 45.3% OOS. In the national ranking, 393.86A2 sits at #1249 out of 3,036 FMCSR codes by citation volume. It's a compliance issue that inspectors flag, but the enforcement data shows it's treated as a correctable defect, not a critical safety hazard.
Yes. The FMCSA DataQs system allows drivers and carriers to challenge roadside inspection records (RDRs) that appear inaccurate. For 393.86A2, contestability depends on the evidence: if the inspector documented a photo or detailed the defect clearly, your challenge must dispute that documentation. If the ICC bumper was actually present and properly mounted, you can submit photos and maintenance records as counter-evidence. Submit your DataQs request within 90 days of the citation. Success requires clear documentation that the bumper met regulatory standards at the time of inspection.
Over the last 180 days, our inspection database shows Texas leads by far with 33 citations and 0 out-of-service placements (0.0% OOS rate). Illinois follows distantly with just 1 citation. Texas accounts for the vast majority of 393.86A2 enforcement in recent months. If you're operating in Texas, pay extra attention to ICC bumper condition during your pre-trip inspections, as state and local inspectors there are actively citing this defect. This concentration may reflect higher inspection volume in Texas or regional focus on older equipment.
Moderately urgent. Our 12-month trend shows 92 citations for 393.86A2 with zero OOS placements, and recent months (March 2026: 5 citations, February 2026: 4 citations) remain steady. The trend is not spiking, but the violation stays on your record. Since you won't be pulled from service, you have time to schedule a repair with your regular shop—ideally within a week or two before your next inspection cycle. Delaying repair increases the risk of another citation and compounds CSA points if you're inspected again. Proactive repair also signals compliance to insurers and brokers evaluating your safety record.
Both. The citation records on your FMCSA SAFER profile under your driver account, and the same event records under your carrier's USDOT number. CSA violations feed into carrier safety ratings used by brokers and insurers to evaluate both driver and fleet risk. Our data shows KB Custom Ag Services LLC, VRP Transportes de Mexico, and Antunez Trucking LLC each have 3 all-time citations for 393.86A2—indicating this is a fleet-wide maintenance issue at those carriers, not isolated driver events. As a driver, maintain your equipment to protect your own safety record and your carrier's.
