What 393.13(a) means in plain language
FMSCR 393.13(a) requires that your commercial motor vehicle be equipped with retro-reflective sheeting or reflex reflectors. In simpler terms: your truck needs reflective materials on the right parts of the vehicle so that other drivers and enforcement officers can see you clearly, especially at night or in low-light conditions.
These reflectors serve a critical safety function. They bounce light—from headlights or flashlights—back toward the source, making your vehicle visible when ambient light is low. This isn't just about aesthetics; it's about preventing collisions and protecting yourself and others on the road. The regulation is straightforward: if your CMV doesn't have the required reflective sheeting or reflex reflectors in the locations and configurations mandated by the standard, you're in violation.
What our enforcement data actually shows
Across our 13 million+ roadside inspection records, we have documented 495 all-time citations for 393.13(a). Notably, there have been 0 citations in the last 12 months and 0 in the last 90 days, indicating this violation is relatively rare in current enforcement activity. None of the 495 citations resulted in an out-of-service order, meaning the OOS rate for this code is 0.0%—significantly lower than the all-FMCSR average OOS rate of 31.4%.
This code ranks #927 out of 3,036 FMCSR codes by citation volume, placing it well below the most frequently cited violations. The absence of recent citations and the zero out-of-service rate suggest that either compliance with this regulation is widespread, or enforcement focus has shifted to other vehicle maintenance priorities. Regardless, a citation for this violation remains a mark on your safety record and fleet profile.
Who gets cited most
Our inspection records do not include state-level breakdown data for this specific code. However, we can identify the carriers with the highest citation counts. GONZALEZ PALLETS INC (USDOT 990181) has received 4 citations for 393.13(a) across our database. SERVICIOS DE AUTO FLETES INTERNACIONALES S DE RL DE CV (USDOT 650903) and CF&M OIL FIELD SERVICE INC (USDOT 404922) each have 3 citations. These data points reflect patterns in our inspection records and do not imply systemic negligence—they simply show which fleets appear most frequently in this violation category.
Looking at vehicle makes, we see that Freightliner (FRHT) tractors account for 54 citations, Peterbilt (PTRB) for 45, and Kenworth (KW) for 29. This distribution likely reflects the overall prevalence of these makes in the trucking fleet rather than a defect inherent to any single manufacturer.
How severe is this compared to similar codes
Within the Vehicle Maintenance category, 393.13(a) stands apart in both citation frequency and enforcement outcome. The most similar code, 393.11 (Lighting devices/reflectors), has generated 179,734 citations with a 1.8% OOS rate—far higher in volume but comparable in severity. 393.9(a) (Inoperable required lamps) has been cited 660,737 times with a 15.4% OOS rate, making it substantially more common and more likely to result in out-of-service placement.
In contrast, 396.17(c) (No proof of periodic inspection) has 198,331 citations but a 0.0% OOS rate, matching 393.13(a)'s OOS profile but with much higher enforcement volume. The data suggests that reflector and sheeting deficiencies are treated as correctable maintenance items rather than imminent safety hazards—hence no out-of-service placements in our records.
How to avoid it
Preventing a 393.13(a) citation starts with a thorough pre-trip inspection focused on visibility components:
-
Inspect all reflective surfaces during your walk-around. Check the sides, rear, and any conspicuity striping on your tractor and trailer. Look for missing, peeling, cracked, or faded reflective material. Run your hand over these areas to feel for loose sections that may have started to lift.
-
Verify reflector placement and condition on trailers. Trailers (TRLR in our data, with 10 citations) are frequent subjects of this violation. Ensure red reflectors are present on the rear, amber on the sides, and white where required by regulation. Replace any that are damaged or discolored.
-
Pay special attention if you operate a Freightliner or Peterbilt. While these vehicles dominate our citation data by sheer numbers, a focused inspection of reflective components on these makes can catch problems before they become violations.
-
Document your pre-trip reflector check. Take photos or note specific observations of reflector condition in your logbook or vehicle inspection report. This creates a record that you were vigilant and can support your defense if a citation is questionable.
-
Replace worn or missing reflectors promptly. Reflective sheeting and reflex reflectors are maintenance items with finite lifespans. Sun, weather, and road salt degrade them over time. If you notice fading or damage during any inspection, schedule replacement before you're stopped at roadside.
-
Understand your fleet's maintenance schedule. If you drive for a carrier, ask your safety manager or maintenance team when reflector condition is checked. Advocate for annual or semi-annual inspections if they're not already routine, especially for vehicles operating in harsh weather or high-mileage environments.
