How to challenge a CSA violation with DataQs

Updated October 1, 2026 · TruckPro Safety Carma

The short answer

DataQs is FMCSA’s system for challenging federal and state safety data you believe is wrong, such as a roadside violation or crash. You file a Request for Data Review (RDR) with evidence. Under rules in effect since September 2026, states must decide an Initial Review within 21 days, you can ask for Reconsideration and then Final Review within 30 days of each decision, and the burden of proof is on you.

What you can challenge

DataQs is for federal and state data that FMCSA publishes and that you believe is incomplete or incorrect. Common carrier requests include:

an inspection or crash assigned to the wrong carrier (“not ours”);
a violation that was cited incorrectly or doesn’t match the facts;
a violation tied to a citation that was dismissed or resulted in a not-guilty finding in court;
a crash that does not meet the reportable crash standard.

Crashes that FMCSA determines were not preventable through its Crash Preventability Determination Program are excluded from the Crash Indicator BASIC.

Step by step

Pull the record. Get the inspection report and find the exact violation code, inspection date, state and report number in SMS.
Read the regulation. Check the cited section and any FMCSA guidance. Be clear about why the violation is wrong, not just that you disagree with it.
Gather evidence. Repair orders and invoices dated before the inspection, photos, ELD records, bills of lading, vehicle and driver lists, and court records for a dismissed citation.
Sign in to DataQs. DataQs requires multifactor authentication. Motor carriers sign in through the FMCSA Portal, and other users through Login.gov.
File a Request for Data Review. Choose the right category (inspection, crash and so on) and reason, explain the facts briefly, and attach every document in this first request.
Watch for requests for information. If the state asks for more, you have 14 days to answer, or the request may be closed with “No Requestor Response”.
Appeal if needed. If you disagree with the decision, request Reconsideration, then Final Review, each within 30 days of the previous decision.

The 2026 rules: deadlines and independence

FMCSA set new requirements for states that review DataQs requests as a condition of their MCSAP grant funding. They were published April 16, 2026, and DataQs began operating under them in September 2026.

Stage	Who decides	State deadline
Open the request	State DataQs analyst	7 days
1. Initial Review	State agency. The issuing officer cannot be the sole decision-maker on a denial.	21 days
2. Reconsideration	A subject matter expert or panel independent of the Initial Review, not the officer or the officer’s immediate supervisor	21 days from your request
3. Final Review	A responsible decision-maker or independent panel not involved in either earlier decision	45 days from your request

The burden of proof is on the requester. States can reject a request without full review if it has no factual or legal justification.

Tips that make a difference

File early. Evidence such as dated repair records and witness memories is easiest to gather right after the inspection.
Lead with documents. A dated invoice beats a paragraph of explanation.
Be specific and calm. Name the violation code, the fact that’s wrong, and the document that proves it.
Include everything up front. New, unrequested evidence on appeal sends the request back to Initial Review.
Check the result. After a correction, confirm the change shows up in the next monthly SMS update.

Find the records worth challenging

TruckPro lists every inspection and violation behind each BASIC, with codes, units and dates, so you can spot records that don’t look right before they cost you months of weight. Apply for early access.

Frequently asked questions

How long does a DataQs review take?

Under FMCSA’s 2026 requirements, states must open a request within 7 days, decide the Initial Review within 21 days, decide a Reconsideration within 21 days of your request, and decide a Final Review within 45 days. The clock pauses while the state waits up to 14 days for information it asked you for.

How many times can I appeal a DataQs decision?

There are three stages: Initial Review, Reconsideration and Final Review. You must request each appeal within 30 days of the previous decision. After Final Review, FMCSA treats the state’s decision as final.

Who decides a DataQs request?

For roadside inspections, the state agency whose officer did the inspection decides. The issuing officer cannot be the sole decision-maker on a denial, and Reconsideration and Final Review must be done by people who were not involved in the earlier decisions.

Can I add new evidence on appeal?

If you submit new, unrequested evidence at Reconsideration or Final Review, the request is sent back to Initial Review so the new evidence gets a full evaluation. Put all your evidence in the first request.
