374.313B-PC FMCSR Citation: Your Q&A Guide

No. Our inspection records show a 0.0% out-of-service rate for 374.313B-PC across all 8 all-time citations in our database. This violation is not OOS-eligible, meaning inspectors cannot place your vehicle out of service solely for this citation. However, the national average out-of-service rate across all FMCSR codes is 31.4%, so you're looking at a significantly lower-severity violation.

This is a low-severity citation. Across 13 million inspections, peer codes in the same category show varying enforcement patterns—for example, 376.11(d)(1) has 6,383 citations with a 0.0% OOS rate, while 999 has 4,802 citations with a 12.1% OOS rate. At 8 all-time citations, 374.313B-PC ranks #2269 out of 3,036 FMCSR codes by citation volume, placing it well below the national average enforcement frequency.

First, confirm the citation details on your inspection report—make sure the violation code, date, and vehicle information are correct. Second, photograph any cited equipment or documentation as evidence. Third, review your maintenance records to understand the root cause. Fourth, contact your carrier's safety department to report the citation and discuss any required corrective actions. Finally, if you believe the citation is inaccurate, you have the right to contest it through the DataQs Roadside Dispute Resolution process within 90 days of issuance.

Enforcement is extremely rare. Our inspection records show zero citations for 374.313B-PC in the last 12 months and zero in the last 90 days as of April 2026. The 8 all-time citations in our 13 million-record database are distributed across only 4 carriers, with TUFESA USA LLC (USDOT 1215199) accounting for 5 of them. This suggests the violation is either archaic, narrowly scoped, or rarely observed in roadside practice.

Yes. You have the right to file a Roadside Dispute Resolution (RDR) challenge through the DataQs portal within 90 days of citation issuance. To be successful, you'll need to demonstrate either a factual error in the inspection record (such as incorrect VIN or inspection date), documentation that proves compliance at the time of inspection, or evidence that the inspector misidentified the violation. Documentation-based defenses are generally stronger than equipment-based ones, so gather maintenance logs, driver logs, and communication records.

TUFESA USA LLC (USDOT 1215199) accounts for 5 of the 8 all-time citations for this code across our database of 13 million inspections. The remaining three citations are spread across PRIMAVERA TOURS LLC (USDOT 702548), SALAMANCA TOURS LLC (USDOT 984609), and AUTOBUSES EJECUTIVOS LLC (USDOT 1044521), with one citation each. All four carriers operate commercial passenger or tour bus operations, suggesting the violation may be tied to passenger transport regulations.

This is low urgency. Since the code carries a 0.0% out-of-service rate and has generated zero citations in the past 90 days, immediate enforcement pressure is minimal. However, you should still address the underlying issue promptly—repeated citations across your fleet (even rare ones) can trigger a carrier investigation. Our data shows only 8 citations all-time, so if your company is among those, your carrier's safety team may already be monitoring this violation type closely.

Our inspection database shows only two vehicle makes cited for this violation: SCANIA and VOLVO, each with 1 citation. The extremely small sample (8 total citations across 13 million inspections) means no clear pattern emerges by make or model. Given the carrier names and low citation volume, this violation appears to affect a narrow segment of commercial vehicles, possibly specialty or imported equipment used in passenger transport operations.
