FMCSR 393.25(e): Obscured Rear Lamps — Driver Q&A

No, this violation is not eligible for an out-of-service order. Across our 13 million inspection records, 393.25(e) citations resulted in an out-of-service placement only 1.4% of the time—32 trucks out of 2,186 not placed OOS. This is far below the 31.4% national average across all FMCSR codes, meaning inspectors rarely impound for obscured rear lamps. You can typically continue operating after the citation is issued.

This violation carries a CSA severity weight of 3, which is relatively light. In the 30-day rolling period after citation, you'll accumulate points based on that weight in the Vehicle Maintenance BASIC. The exact point total depends on your carrier's CSA profile and whether other violations are cited at the same time. Weight 3 is in the lower range, so impact on your CSA score is modest compared to more serious violations.

First, photograph the load coverage and lamp visibility from multiple angles—this creates a record for any dispute. Second, confirm with your dispatcher or safety manager that the load is properly secured and rear lamps are fully visible. Third, review whether a tailboard, cargo net, or straps are actually blocking the lights, or if the inspector's finding was unclear. Finally, file a DataQs dispute if you believe the lamp was not obscured; our inspection database records show this violation is contestable based on visibility documentation and load configuration photos.

No, it's among the least serious lamp violations. Across our records, the peer code 393.9(a) — inoperable required lamps — has a 15.4% OOS rate and 660,737 citations. By contrast, 393.25(e) has only a 1.4% OOS rate across 2,218 all-time citations and ranks #516 of 3,036 FMCSR codes by frequency. Code 393.11 (lighting devices/reflectors) shows a 1.8% OOS rate, also higher than 393.25(e). Your citation is for an obstruction, not equipment failure—less severe.

Yes. DataQs allows you to challenge inspection findings through the Federal Motor Carrier Safety Administration's records dispute process. For 393.25(e), you can contest the finding by submitting evidence that rear lamps were not actually obscured—load photos, pre-trip inspection logs, or third-party documentation showing lamp visibility. Since this code depends on the inspector's visual assessment of obstruction, clear photographic evidence is your strongest argument. Submit your dispute within 90 days of the citation date through the SafetyNet portal.

Our inspection records show zero citations for 393.25(e) in the last 12 months and last 90 days, despite 2,218 all-time citations. This suggests enforcement on this specific violation has dropped sharply or inspectors are citing related codes instead—such as 393.9 (inoperable lamps) or 393.11 (lighting defects). The trend indicates this particular obstruction citation may be less common in current roadside inspection practice, so encountering it today is relatively unusual.

Freightliner trucks dominate the citation count with 172 citations, followed by FRHT units with 146 citations. Kenworth (70), Ford (76), and International (69 + 51 as INTL) also appear frequently. These are standard Class 8 tractor models used by large carriers. The prevalence reflects their market share in the trucking fleet, not necessarily higher violation rates. Ensuring load coverage on any trailer type—especially when hauling freight that extends to the sides—is the key to avoiding this citation.

You can address it before your next inspection without urgency. With a 1.4% OOS rate and zero citations in the last 90 days, this violation is not a critical safety flag. The fix is simple: ensure your load is properly secured so rear lamps and reflectors are fully visible, or use a step-deck trailer if your cargo requires it. Check your vehicle's pre-trip inspection log to confirm lamps are clean and functional. No emergency repair is needed—compliance is mainly about load securement practice.
