What 374.313C-PC means in plain language
374.313C-PC is a specific FMCSR citation issued during roadside inspections. While the exact regulatory language is technical, this code flags a particular compliance gap that roadside inspectors are trained to identify during vehicle or operational checks.
Because citations under this code are rare—our database shows only 4 all-time—inspectors who issue it are typically responding to a clear and measurable discrepancy. Understanding what triggered your citation is the first step in preventing another one. Ask the inspector or review the citation document to identify exactly which aspect of the regulation was not met at the time of inspection.
What our enforcement data actually shows
Across our 13 million+ real roadside inspection records, 374.313C-PC has been cited only 4 times in all-time records. In the last 12 months, there were 0 citations. In the last 90 days, there were 0 citations.
None of those 4 all-time citations resulted in an out-of-service order. The OOS rate for this code is 0.0%—meaning every citation issued has allowed the driver and vehicle to continue operating. This stands in sharp contrast to the all-FMCSR average OOS rate of 31.4%, indicating that inspectors have consistently judged 374.313C-PC violations as not severe enough to remove the vehicle from service immediately.
Ranked #2480 of 3,036 FMCSR codes by citation volume, 374.313C-PC is extremely uncommon. The rarity of enforcement means you're in a small group, and the fact that no citations have triggered out-of-service status suggests the violation, while worth correcting, does not pose an imminent safety risk by regulatory standards.
Who gets cited most
Our data is too sparse to reliably rank states by citation count; with only 4 all-time citations, state-level patterns are not meaningful. However, our records show that fleets such as Tribal Sun Bus LLC, El Expreso Group LLC, MT Diablo Unified School District, and Montebello Unified School District have each received 1 citation under this code. These citations came from a mix of vehicle types, with BLUB-branded vehicles appearing twice, and Peterbilt and Reitnouer vehicles each appearing once.
Because this code is so rarely cited, neither carrier history nor vehicle make predicts risk reliably. Focus on the specific deficiency noted on your citation.
How severe is this compared to similar codes
Peer codes in the same category show a wide range of enforcement intensity. Code 376.11(d)(1) has been cited 6,383 times with a 0.0% OOS rate—far more frequent but equally non-severe in terms of immediate removal. Code 999 has 4,802 citations and a 12.1% OOS rate, suggesting some citations result in out-of-service orders. Code 107.620(b), with 2,120 citations, has a 0.2% OOS rate, and 107.620B-HMAMC, with 1,820 citations, has a 0.0% OOS rate.
By comparison, 374.313C-PC is enforced far less frequently than any of these peer codes, and its 0.0% OOS rate matches the least severe in the group. This suggests it addresses a lower-risk compliance gap or one that inspectors encounter only under specific operational conditions.
How to avoid it
Because 374.313C-PC citations are extremely rare in our database, the specific trigger is not clearly defined by enforcement patterns alone. However, here are concrete steps to minimize your citation risk:
- Review your citation document carefully. The inspector noted a specific deficiency. Correct that exact item before your next inspection.
- Perform a thorough pre-trip inspection. Focus on any equipment, documentation, or operational procedure the citation mentioned. Most roadside citations flag items that a careful walk-around would catch.
- Verify your vehicle's maintenance records. If the citation involved equipment condition, ensure your shop has documented recent inspections and repairs. Carriers like those cited above operated various makes; regardless of your vehicle brand, consistent maintenance prevents most compliance gaps.
- Ask your dispatcher or safety manager to clarify the regulation and what the inspector observed. A brief conversation can prevent repeat citations and keep your safety record clean.
- Check your logbook and hours-of-service compliance. Many citations are paired with HOS violations; if your citation came during a routine check, ensure your records are accurate and current.
Because enforcement of this code is rare, a single citation is unlikely to trigger carrier or insurance-level penalties on its own. However, correcting the underlying issue ensures you stay compliant and avoid compounding violations during future inspections.
