FMCSR 392.2-CONSZ: Speeding in Construction Zone — Q&A

No. Across our inspection records, the out-of-service rate for 392.2-CONSZ is 0.0%. This means that when this violation is cited, it does not result in an immediate roadside out-of-service order. However, the violation itself carries a CSA severity weight of 7, so it will still impact your safety profile and can contribute to escalated enforcement if patterns emerge.

The CSA severity weight for this violation is 7. In FMCSA's CSA system, violations in the Unsafe Driving BASIC are weighted and multiplied over a rolling 30-month period. A single 392.2-CONSZ citation carries a base severity of 7 points; the total impact on your BASIC score depends on how many other citations you accumulate in that same period.

Immediately after citation:

1. Request the inspection report — get a copy of the citation with the exact location, posted speed limit, and measured speed recorded.
2. Document the construction zone — photograph or video the signs, lane markings, and conditions from the date of the stop.
3. Note your truck's equipment — ensure speedometer calibration records are current; discrepancies can be grounds for DataQs challenge.
4. Contact your carrier's compliance team — report the citation so it can be logged in your file.
5. Review the violation date and location — verify the inspector's determination that you were in a designated work zone when cited.

The severity depends on context. Our data shows peer violations in the Unsafe Driving category—such as speeding 6–10 mph over the limit (392.2-SLLS2)—have a 0.0% out-of-service rate and accumulate at much higher citation volumes. However, construction zone speeding carries the same CSA severity weight of 7, making it equally serious from a safety scoring perspective, even though roadside placement out of service is rare for both.

Yes. The FMCSA DataQs RDR (Roadside Inspection Documentation Review) process allows you to challenge citations by submitting evidence that contradicts the inspector's findings. For construction zone speeding, contestable evidence includes: photos of missing or illegible speed-limit signs, proof that the zone was not properly designated on the citation date, speedometer calibration records showing a measurement error, or official records from the road authority showing the zone was not active. Submit your challenge with documentation within the timeframe specified on your citation notice.

Our inspection database shows 0 citations for 392.2-CONSZ in the last 12 months and 0 all-time. This code is extremely rarely enforced in the national roadside inspection program. While construction zone speeding is a legitimate safety violation, it is not a common citation category in the FMCSA inspection data we track across 13 million records.

While 392.2-CONSZ itself carries a CSA severity weight of 7 and is out-of-service eligible, the enforcement volume is so low that it is not a widespread pattern. The real urgency is preventing future citations: always obey posted speed limits in construction and work zones, as these areas carry heightened safety risk. A single citation won't trigger immediate compliance action, but repeated unsafe driving violations will accumulate points in your CSA BASIC score.

Both. Under FMCSA's CSA system, violations in the Unsafe Driving BASIC—including 392.2-CONSZ—affect both your personal driver record and your carrier's Safety Management BASIC score. The violation appears on your Motor Vehicle Report (MVR) for 36 months and counts toward your carrier's unsafe driving metric. If you drive for a fleet, this citation impacts both profiles.
