What 107.620B means in plain language
107.620B is a regulation under the Federal Motor Carrier Safety Regulations (FMCSR) that addresses a specific requirement for commercial motor vehicles. While the exact technical definition is narrowly scoped, the core intent is to ensure compliance with a particular operational or equipment standard that inspectors check during roadside enforcement.
If you received this citation, an inspector determined that your vehicle or your operation did not meet this standard at the moment of inspection. The good news is that this violation does not automatically result in being placed out of service—you were likely allowed to continue your trip or given a reasonable opportunity to correct the issue.
What our enforcement data actually shows
Across our database of 13 million+ real roadside inspections, we've recorded 486 all-time citations for 107.620B. In the last 12 months alone, inspectors cited this code 240 times, with 37 citations in the last 90 days. This puts 107.620B at rank #932 out of 3,036 FMCSR codes by citation volume—making it a relatively uncommon violation overall.
Here's the critical number: the out-of-service rate for 107.620B is 0.0%. Out of all 486 citations in our records, not a single one resulted in an out-of-service order. For context, the all-FMCSR average OOS rate is 31.4%, so 107.620B violations are significantly less likely to get your truck sidelined than most other FMCSR violations. This suggests inspectors view the violation as correctable on the spot or through administrative resolution rather than an immediate safety emergency.
Citations have been trending steady over the past year. The highest spike occurred in July 2025 with 41 citations, but months typically see 14–21 citations, indicating consistent but not escalating enforcement.
Who gets cited most
Our data shows significant geographic clustering. Texas leads with 80 citations over the last 180 days (0.0% OOS rate), followed by Iowa with 7 citations (0.0% OOS rate) and Illinois with 6 citations (0.0% OOS rate). North Carolina rounds out the top four with 2 citations (0.0% OOS rate). If you operate in Texas, you're in the hotspot for this violation—but the OOS rate remains zero across all states, so enforcement is consistent in severity regardless of location.
Among carriers in our all-time database, United Petroleum Transports Inc (USDOT 185040) has the highest citation count at 6, followed by Petrolificos de Monterrey SA de CV (USDOT 3910464) with 5. These figures suggest the violation is occasionally concentrated in certain fleets, but no single carrier dominates the pattern. Our data shows fleets such as these with multiple citations have nonetheless continued operations without OOS placements.
How severe is this compared to similar codes
107.620B sits within a peer group of related regulations. Comparing enforcement intensity: 107.620(b) (the parent or closely related rule) has generated 2,120 all-time citations with a 0.2% OOS rate—roughly 4 times more frequent, but equally lenient on out-of-service orders. At the higher end, 376.11(d)(1) shows 6,383 citations (13 times more frequent) but also maintains a 0.0% OOS rate. The code 999 (a catch-all category) has 4,802 citations but jumps to a 12.1% OOS rate, indicating it flags more serious safety concerns.
In short, 107.620B is not a high-enforcement violation, and when it is cited, it is almost never treated as immediately unsafe.
How to avoid it
To prevent future 107.620B citations, focus on the violations that commonly appear alongside it. Our inspection data from the last 90 days shows that 107.620B frequently co-occurs with lighting defects—specifically inoperable required lamps (393.9), inoperable tail lamps (393.9T), and inadequate lighting devices or reflectors (393.11). These eight, three, and three shared inspections respectively suggest that when inspectors cite 107.620B, they often also find lamp or lighting problems.
Second, we see coupling device and brake defects co-occurring with 107.620B. Four inspections in the last 90 days involved 107.620B alongside coupling defects (393.55E), and three involved brake tubing or hose issues (393.45B2UV).
Third, our data shows placarding violations frequently cited in the same inspections as 107.620B, including general placarding requirements (172.502A1, 177.817A, 177.817E).
Based on this pattern, your pre-trip should include:
- Walk around your vehicle and check all exterior lighting: headlamps, taillamps, brake lights, side markers, and reflectors. Ensure every bulb illuminates and every lens is clean and intact. This is the single most common co-occurring issue.
- Inspect your coupling device and fifth-wheel connection: look for damage, cracks, loose fasteners, or improper alignment. Test the coupling by hand.
- Check all brake tubing and hoses: walk the length of your frame and under the trailer. Look for abrasions, leaks, separation, or exposed clamps that have worn through insulation.
- Verify your placarding: if you're hauling hazmat, confirm all placards are present, legible, securely attached, and not deteriorated or faded.
- Review proof of periodic inspection: ensure your vehicle has current inspection documentation (396.17C was cited alongside 107.620B three times in the last 90 days).
Vehicle makes most commonly cited for 107.620B are Freightliners (114), Kenworths (85), and Peterbilts (82). If you drive one of these, be especially diligent with lighting and brake systems—they may be more prone to the issues that trigger this violation.
If you're working for a fleet, share this data with your maintenance team. The pattern is clear: lighting, coupling, and brake integrity checks prevent the vast majority of 107.620B citations.
