DataQs challenges

DataQs: how to challenge inspections and crashes

The short answer

DataQs is FMCSA's online system for requesting a review of federal and state safety data, such as roadside inspection violations and crash reports, that you believe is inaccurate or incomplete. You file a Request for Data Review at dataqs.fmcsa.dot.gov, it is routed to the state agency that reported the data, and if your challenge is accepted the record is corrected or removed, which can lower your CSA scores.

What you can challenge

  • Inspection violations that were recorded incorrectly, cited under the wrong regulation, or not supported by the facts
  • Violations tied to citations that were dismissed or found not guilty in court
  • Crashes that don't meet the reportable definition, were assigned to the wrong carrier, or are duplicates
  • Inspections assigned to the wrong carrier or the wrong driver
  • Crash preventability for eligible crash types, through the CPDP

How to file a strong DataQs challenge

  1. Pick the right records. Focus on violations with high severity weights, out-of-service violations, and recent events, since they move your scores most.
  2. Gather evidence. Inspection report, ELD records, repair invoices, photos, dash cam video, court documents or the police report.
  3. Write a short, factual explanation. Cite the regulation, explain specifically why the record is wrong, and attach proof. Avoid emotion and arguments about fairness.
  4. Submit and track it. The reporting state reviews the request and posts a decision in DataQs.
  5. Follow up. If it's denied and you have new information, you may be able to request reconsideration.

Common mistakes

  • Challenging violations that were accurate; reviewers notice, and it hurts credibility
  • Filing without documents, or with documents that don't address the specific violation
  • Waiting too long, so evidence like dash cam video is gone
  • Ignoring dismissed citations, which are some of the easiest wins

Frequently asked questions

Is there a deadline to file a DataQs challenge?

FMCSA doesn't set one strict deadline for most requests, but evidence fades and violations hurt you most while they're recent. File as soon as you have documentation.

Does a dismissed ticket remove the violation from my CSA score?

If the citation tied to a violation was dismissed or you were found not guilty, you can submit the court documents through DataQs to have the violation removed or noted, which takes it out of your SMS measures.

Who decides a DataQs challenge?

Requests are routed to the agency that reported the data, usually the state that performed the inspection or reported the crash. FMCSA handles some request types, including crash preventability.

Does it cost anything to file a DataQs request?

No. Filing through DataQs is free.
