Section 392.2 says every commercial motor vehicle "shall be operated in accordance with the laws, ordinances, and regulations of the jurisdiction in which it is being operated." When the violation is "failure to obey a traffic control device," FMCSA codes it as 392.2FC. Stop signs, red lights, yield signs, lane-use signs, no-turn signs — all of it falls under this code.
Severity weight
392.2FC carries a severity weight of 5 in the Unsafe Driving BASIC. The weight runs through the Safety Measurement System for 24 months, time-weighted so recent citations hit hardest. A pattern of 392.2FC findings is a leading indicator FMCSA flags during compliance reviews.
How to prevent it
- Add traffic-control compliance to your driver-orientation curriculum and document the training.
- Use telematics events (hard braking near intersections, harsh acceleration) to identify drivers needing coaching before a citation.
- Review every roadside inspection with the driver — even non-citation findings — so patterns surface early.
- Re-train after every 392.2 citation; document the re-training in the driver's qualification file as §391.25(c)(2) reflects the carrier's ongoing duty to evaluate driver fitness.
How Roadworthy HQ helps
A traffic-control citation lands on the driver. Roadworthy HQ does not record individual violation codes, pull CSA or SMS scores, or track coaching. What it keeps is the driver file an auditor opens next: the annual MVR and the §391.25 annual review, each with reminders 60, 30, and 7 days out, and the qualification-file documents with their retention periods enforced. If the citation came from a roadside inspection, log that inspection on the vehicle (date, state, level, driver, number of violations, out-of-service or not).
