What 393.95(k) means in plain language
393.95(k) addresses a specific requirement for commercial vehicle equipment maintenance and condition. The regulation requires that certain components or systems meet defined functional standards during roadside inspection. When an inspector cites this code, they've documented that your vehicle did not meet that particular equipment standard at the time of inspection.
This is a maintenance and equipment defect citation. Unlike some violations that pose immediate safety risks, this code focuses on compliance with equipment specifications that should be corrected during routine vehicle servicing or maintenance cycles.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.95(k) has generated only 336 all-time citations nationwide. In the last 12 months and last 90 days, our database shows zero citations for this code—meaning it's an extremely uncommon violation in current enforcement.
Crucially, zero out of 336 citations resulted in an out-of-service placement. The OOS rate for 393.95(k) is 0.0%. This stands in sharp contrast to the all-FMCSR average OOS rate of 31.4%, placing this code in the lowest-risk tier for enforcement severity. This tells you that inspectors are treating 393.95(k) violations as correctable defects rather than safety-critical failures.
Ranked #1053 out of 3,036 FMCSR codes by citation volume, 393.95(k) is statistically one of the least-cited vehicle maintenance violations in the database.
Who gets cited most
Our inspection records show that citations for 393.95(k) are dispersed across many carriers rather than concentrated in any one fleet. The highest-cited carriers in our all-time data are Fletes Express del Norte SA de CV and NextGen Transport Inc, each with 2 citations. Because citation counts are so low overall, no geographic pattern or fleet-specific trend is statistically meaningful.
The absence of repeat citations across carriers suggests that 393.95(k) violations are incident-driven rather than systemic—meaning a single inspection event rather than a pattern of maintenance failures.
How severe is this compared to similar codes
When you place 393.95(k) alongside other vehicle maintenance codes in our database, the picture becomes clear:
- 393.9(a) — Inoperable required lamps: 660,737 citations, 15.4% OOS rate. This is dramatically more frequently cited and carries much higher enforcement risk.
- 396.3(a)(1) — Inspection/repair/maintenance (general): 236,919 citations, 45.3% OOS rate. This catch-all maintenance code has 704 times more citations than 393.95(k) and an OOS rate 45 percentage points higher.
- 396.17(c) — No proof of periodic inspection: 198,331 citations, 0.0% OOS rate. This code matches 393.95(k)'s zero OOS rate but is cited 590 times more often.
Your citation is in the rarest and lowest-enforcement tier of maintenance violations. The zero OOS rate indicates that inspectors and enforcement agencies do not consider this a vehicle safety condition requiring immediate removal from service.
How to avoid it
Because 393.95(k) citations are so rare and recent enforcement volume is zero, the best guidance is to maintain a robust pre-trip and routine maintenance schedule:
- Perform a complete vehicle walk-around before every shift. Check lighting, wiper condition, mirror attachment, and all visible equipment fasteners. Tighten or replace anything loose or damaged.
- Document your pre-trip inspections. Many 393.95(k) citations arise during roadside inspection when an inspector discovers an equipment condition that wasn't caught in your pre-trip. A dated, signed pre-trip record demonstrates due diligence.
- Address equipment defects immediately. If you find a loose component, cracked lens, or non-functional feature during your walk-around, don't defer repair. Fix it before operating the vehicle.
- Know your vehicle make and maintenance intervals. Our inspection data shows citations across Ford (76), Freightliner (46), Dodge (38), and International (30) trucks. Consult your manufacturer's recommended maintenance schedule for your specific make and model, and stick to it.
- Use the 30-day pre-roadside-inspection rule. If you know an area has active roadside inspection activity, conduct your own equipment audit in the week prior. Replace worn wipers, ensure all lights function, and verify that mirrors and fasteners are secure.
The fact that zero citations have resulted in out-of-service placement means this violation is correctable and not a barrier to your operation—but it's still a citation that creates paperwork and potential carrier scrutiny. Prevention through consistent pre-trip attention is the simplest strategy.
