How to challenge a violation through DataQs
What DataQs can and can't remove, how to write a request that gets accepted, and how a win changes the numbers on your record.
What DataQs is
DataQs is FMCSA's system for asking that a crash or inspection record be reviewed. The request goes to the state agency whose officer wrote the report, not to FMCSA. If the state agrees, the record is corrected or removed and your SMS measures are recomputed in the next monthly snapshot.
What gets fixed, and what doesn't
- Usually accepted: the violation was assigned to the wrong carrier (wrong USDOT on the report), a duplicate record, a crash that wasn't yours, or a citation that was later dismissed in court (attach the court disposition).
- Crash Preventability Determination Program: certain crash types — being struck by a vehicle going the wrong way, rear-ended while legally stopped, animal strikes, and others — can be reviewed as "not preventable". If accepted, the crash stays in the record but is excluded from your Crash Indicator measure.
- Rarely accepted: "the officer was wrong about the brake adjustment" with no evidence. The reviewing state generally sides with its own inspector unless you bring documentation.
Writing a request that works
- Create an account at dataqs.fmcsa.dot.gov with your USDOT number.
- Pick the exact record (inspection report number or crash report number) — it's on the inspection sheet you were handed.
- State the single specific error in the first sentence. One issue per request.
- Attach evidence: the inspection report, photos taken at the scene, repair invoices dated the same day, court dismissal, bill of lading showing the load belonged to another carrier.
- Keep it factual and short. Reviewers process hundreds of these.
You can appeal a denial once, and FMCSA published a formal appeals process in 2024 that lets you escalate a second time on certain grounds. Most decisions come back within a few weeks.
After a win
Corrections apply on the next SMS update, published monthly. Your report card here updates on the same cycle. Keep the DataQs confirmation — insurers and brokers sometimes pull a cached copy of the old record.
