Questions & Answers

Direct answers grounded in TruckCodex inspection data

will 374.313(a) put my truck out of service

No. Our inspection records show that 374.313(a) has never resulted in an out-of-service order. Across all-time enforcement data in our database, both citations resulted in the truck remaining in-service. The 0.0% out-of-service rate for this code is significantly lower than the 31.4% average across all FMCSR violations, meaning inspectors treat this violation as correctable without removing your vehicle from the road.

how serious is a 374.313(a) citation compared to other violations

This is a minor citation. The data indicates 374.313(a) ranks #2651 out of 3,036 FMCSR codes by citation frequency. In the peer codes we track in the same category, violations like 376.11(d)(1) appear 6,383 times—thousands more than this code. The 0.0% out-of-service rate here contrasts sharply with the national FMCSR average of 31.4%, suggesting inspectors view this as documentation or minor procedural rather than safety-critical.

what should I do right after getting cited for 374.313(a)

First, document the citation details and photograph any equipment involved. Review the specific finding on your inspection report—this code typically involves record-keeping or administrative compliance rather than equipment failure. Contact your dispatcher or safety manager immediately with the citation number and date. Request a copy of the full inspection report from the roadside inspector. Since the violation does not trigger out-of-service status, you can continue operating while you address the underlying issue with your carrier's compliance team.

374.313(a) citation—is this a big deal for my driving record

Not compared to enforcement volume in your industry. Our database shows only 2 citations for 374.313(a) across 13 million inspections. This extremely low frequency suggests the violation is uncommon or situation-specific. While any citation affects your record, the negligible citation rate and zero out-of-service outcomes indicate this is not a widespread safety enforcement priority. Work with your carrier to understand the root cause and document your corrective action.

where do most 374.313(a) citations happen

Our all-time enforcement data shows only 2 citations for 374.313(a) total, making state-by-state trends unreliable. Both were cited against carriers with single occurrences: TUFESA USA LLC (USDOT 1215199) and MONTANOS TRUCKING LLC (USDOT 3167334). With such minimal enforcement volume nationally, this violation is rare enough that geographic patterns do not emerge from the inspection records we track.

can I contest a 374.313(a) citation through the DataQs process

Yes. Under the FMCSA DataQs system, you can contest any roadside inspection citation within 90 days. The contestability depends on the type of finding: documentation-based violations are often easier to challenge with corrected records, while equipment defects require physical evidence of repair. Submit your DataQs request through the FMCSA portal with copies of corrective documentation. Since 374.313(a) is infrequently cited, ensure you include clear evidence tied directly to the inspector's specific finding.

374.313(a)—how fast do I need to fix this

There is no emergency timeline. Since this violation has a 0.0% out-of-service rate and only 2 citations in our entire database, it is not treated as an urgent safety defect. You are not required to stop operations or make immediate repairs. However, contact your fleet safety manager within 24 hours to confirm the violation type and agree on a corrective action timeline. Address the issue within 30 days to demonstrate diligence if you decide to file a DataQs contest.

does 374.313(a) follow me as a driver or the carrier

Both. FMCSA CSA safety records track violations against both the individual driver and the carrier. A 374.313(a) citation will appear on your motor carrier's safety profile and may affect your personal CSA score depending on your carrier's reporting structure. Discuss with your safety manager how the carrier classifies this violation and whether it triggers any internal corrective action protocols. The violation stays on record but does not prevent future employment if properly documented and corrected.
