Topic overview
To dispute a violation on your record, you file a request on FMCSA’s DataQs website, and the State whose officer did the inspection decides it. Most owners call this a DataQ challenge. Since September 13, 2026, every State must follow the same steps and deadlines (the rules FMCSA published in April 2026). The State has 21 days to give its first answer. If it says no, you have 30 days to ask for a second review, and the State has 21 days to decide it. If that is no too, you get one final review, decided in 45 days. After that, the State’s answer is final, and FMCSA will not overrule it.
The proof is up to you. Send all the documents that support your case with the first request. A request with no proof can be closed without a review of the facts. New evidence added during an appeal can send your request back to the start. You need to show a specific mistake, such as the wrong truck, driver or DOT number, a violation written twice, or a ticket the court threw out. Simply disagreeing with the officer is not enough. Also, a dismissed ticket can still count against you if someone paid a fine or court costs. The law counts that as a conviction (the federal definition), so the violation stays. And do not wait. A violation counts in your safety scores for 24 months. Most people call them CSA scores. It counts three times over in its first six months (FMCSA’s scoring manual).
Chapter 01
What is DataQs, and who decides my request?
DataQs is FMCSA’s website for fixing a wrong inspection or crash record. You open a request there against one report, say what is wrong, and attach your proof. Most owners call it a DataQ challenge. FMCSA calls it a Request for Data Review, or RDR, and you will see those letters on the site. But FMCSA does not decide it. The State whose officer did the inspection decides it. Since September 13, 2026, every State must do this the same way, with fixed deadlines (the rules FMCSA published in April 2026). The website is at dataqs.fmcsa.dot.gov.
Consider this example. Say you run three trucks. One Monday night in October 2026, you log in to FMCSA’s safety score website to check on your company. You find an inspection from October 6 that you have never heard of. The report says one of your trucks had bad brakes and was put out of service. But the VIN and the plate on the report do not match any of your three trucks. The driver named on it has never worked for you. The inspection of someone else’s truck was entered under your DOT number. Maybe an officer typed one wrong digit. You will never know for sure. You can show that the truck was not yours.
Why should you care? FMCSA turns your inspections into safety scores. Most people call them CSA scores. It uses those scores to pick which carriers get warning letters and investigations (FMCSA’s scoring manual). The scores look back 24 months. A violation counts three times as much in its first six months. It counts twice as much until it is a year old, and once in its second year. Then it drops out. Each violation also gets a weight from 1 to 10 for how serious it is. In the vehicle maintenance group, it gets 2 more if the truck was put out of service. So this brake violation, which is not even yours, now counts at full weight.
A small fleet feels this more than a big one. The score calculation takes account of your inspections, including those with no violations (the scoring manual). A big carrier may have hundreds of inspections to offset one violation. You may have five. So one wrong violation can make up most of your score in that group.
So who fixes it? Not FMCSA. FMCSA runs the website and sets the rules. The State agency that runs truck safety checks, in the State where the stop happened, makes the call. States do this because it is a condition of the federal money they get for truck safety work (the federal rule on that money). Before September 2026, each State did it its own way. Some had a second review and some did not. Some answered within three weeks, and others took longer (the April 2026 rules). Now all of them must follow the same review process and deadlines.
Other owners use this process too. In 2024, DataQs got 63,548 requests about inspections and violations, and 8,314 about crashes (the April 2026 rules). Filing one is normal. The next question is whether yours is the kind DataQs can fix.
Chapter 02
What can DataQs fix, and what can it not?
DataQs fixes a record that is wrong or missing something. It fixes plain mistakes: the wrong truck, the wrong driver, the wrong DOT number, or a violation written twice. It fixes a violation the officer admits was a mistake. It also updates a violation to reflect a qualifying court dismissal. It cannot remove a violation that really happened just because you think it was unfair. And it will not take your word for anything. Under the April 2026 rules, a request with no facts or legal reasons behind it gets turned down. You need evidence to support the correction.
Your case is the clearest kind. Nothing about it is a matter of opinion. The truck on the report is not yours, and papers can show it. This is where DataQs works best.
Other mistakes can be supported with different documents. A wrong name, VIN or plate on the report can be fixed with the paper that shows the right one. Your driver list and payroll can help show that the named driver never worked for you. A violation the officer later admits was wrong can be fixed with the officer’s email or a corrected report.
A warning counts too. Violations written on an inspection report count in your scores “whether or not a citation is issued” (the scoring manual). A citation is a ticket. So a wrong warning is worth fixing, just like a wrong ticket. A warning for a violation that did happen stays on the report.
One case looks bigger than it is. If the same violation code shows up twice on one report, your score already counts it only once (the scoring manual). Fixing it cleans up the report but may not change your score. If two different codes were written for one single problem, that can be worth a request. The report itself is your proof, but the State decides if the two codes really mean the same thing.
Some things are not DataQs matters at all. A drug or alcohol test result, an entry in the Drug and Alcohol Clearinghouse, and your safety rating are all handled elsewhere. When FMCSA asked for comments on the new rules, 43 of them were about the Clearinghouse. FMCSA set them all aside as outside these rules (the April 2026 rules). A crash report with wrong facts can be fixed in DataQs. But asking FMCSA to rule a crash “not preventable” is a separate FMCSA program with its own rules (the scoring manual).
A violation that came with a ticket is a special case. If the ticket is going to court, you wait for the court. The section on tickets below explains what happens next.
There are time limits. The State must take a request about an inspection for 3 years after the inspection. For a crash, it is 5 years after the crash (the April 2026 rules). The time available to improve your scores is shorter. After 24 months, a violation no longer counts in your scores. A request filed in year three fixes the record but not the score. Your inspection is six days old, so you have everything to gain by moving now.
Chapter 03
How do I file a DataQs request?
You file it on the DataQs website, against the one report that is wrong. Say what is wrong, why, and what you want fixed. Then attach the papers that prove each point. The proof is up to you. The rules say the burden of proof “rests entirely with the requestor”, and the requestor is you (the April 2026 rules). The State does not have to prove the violation happened. You have to show that the record is wrong.
Before starting the request, gather the documents that support it. In this example, each document answers a specific question.
First, the details of the inspection itself: the report number, the VIN, the plate and the driver’s name, just as your record shows them. These are the facts you will point to.
Second, the registration cab cards for all three of your trucks. None of them has the VIN or the plate on the report.
Third, your insurance schedule. It lists every truck you run, and there are only three.
Fourth, your ELD records for October 6. They show where each of your trucks was that day. None of them was anywhere near the stop.
Get the full inspection report before writing, not just a screenshot of the violation on your score page. Read every page, including any notes supplied with it. If you lack a copy, ask the issuing agency for one. FMCSA names inspection reports among the documents that can support a request.
What if the truck is yours, but you dispute the violation itself? You still need to show what is wrong. Say the report lists a lamp that did not work. Save photographs or video showing that lamp at the inspection, with the time and vehicle clear. Keep original dashcam footage before it is overwritten. A photo taken after a repair shows the repair, not the lamp’s earlier condition. These are ways to support your account, not a promise that the State will accept it.
Add any existing pre-trip and post-trip reports and the relevant repair records. Do not create a missing report afterward. A clean report from earlier that day does not prove a lamp still worked at the stop. Nor is a written report required after every clean trip: the driver inspection rule has an exception when no defect is found or reported. For a dispute about time or location, preserve GPS and ELD records with their timestamps and time zones. Match each file to the fact you ask the State to correct.
Then check the exact rule behind the violation. For the lamp, read the rule on working lights, especially paragraph (a). It distinguishes required lamps from extra ones. For excess driving time, use the freight driver’s hours limits. If you claim the short-haul exception, check every condition in paragraph (e) of the exceptions rule. Copy the section and paragraph number into your request. Explain which condition the evidence proves. A list of unrelated rules does not explain an error.
Back in your case, the vehicle records show the inspection belongs to another carrier. Now write the request. Keep it short and plain. Say what is wrong, show the proof, and say what you want. Yours could read like this. Fill in the parts in brackets with your own details.
Request to correct inspection report [number], dated October 6, 2026. USDOT [your number].
What is wrong. This inspection is on our record, but the truck was not ours. The VIN [number] and plate [number] on the report do not belong to any truck we run. The driver named on the report has never worked for us.
The proof. We run three trucks. Their cab cards are attached (1). None has this VIN or plate. Our insurance schedule lists only these three trucks (2). Our ELD records show where each truck was on October 6 (3). None was at the place of this inspection.
What we ask. Please remove this inspection and its violations from our record.
Notice what it does not do. It never asks the State to take your word for anything. Every claim points to a supporting document.
Send everything now, even papers you think the State will not need. Adding evidence later can cost you weeks. Suppose you submit a new document during an appeal. If the State never saw it and did not ask for it, your request goes back to the first stage and starts over (the April 2026 rules). The rules also do not list which papers are enough. FMCSA left that to each State to judge case by case. Include all relevant evidence with your first request.
Should you file, or should the driver? DataQs is open to carriers, drivers and others (the April 2026 rules). The violation affects your company’s scores. The papers that prove most mistakes, like cab cards, insurance and payroll, are yours too. So it usually makes sense for you to file. In this case there is no driver of yours to ask anyway.
On October 13, you file. Now the clock starts.
Chapter 04
What happens after I file, and how long does it take?
The State must open your request within 7 days and answer within 21 days of the day you filed. If it asks you for more papers, you have 14 days to send them, and its clock stops while it waits. If the answer is no, you have 30 days to ask for a second review, which must be decided in 21 days. Then you get a final review, decided in 45 days. These are calendar days, not work days. After the final review, the State’s answer is final (the April 2026 rules).
Here is how your case runs. You filed on October 13, so the State must open it by October 20. On October 22, it writes back and asks for a list of the drivers you had on October 6. You send it two days later. Those two days do not count against the State. Its clock stops while it waits for you, then picks up where it stopped. So its first answer, due November 3, is now due November 5.
Answer requests for documents promptly. If you do not answer in 14 days, the State can close your request for lack of an answer. If it already has enough to decide, it decides on what it has. Either way, you are not locked out. If you send the missing papers later, the request opens again at the same stage. The State then gets its full time again (the April 2026 rules). But you lose weeks, and the violation counts against you the whole time.
On November 5, the answer comes, and it is no. The status reads “Closed—No Data Correction Made”. That means the State reviewed the request and declined to change the record. The reason given is short. It says a carrier can lease or borrow a truck. So cab cards for the trucks you own do not prove this truck was not working for you.
You can appeal that refusal. Since September 2026, a refusal must tell you six things (the April 2026 rules). It must say where to find the State’s written plan for DataQs, which FMCSA has approved. It must give the name and title of the person who decided. It must list the evidence they looked at. And it must give the decision, the reasons for it, and how to appeal.
Read the evidence list first. In your letter, it names the report, your cab cards and your driver list. It does not name your insurance schedule or your ELD records. The evidence list leaves out the two documents that address the reason for refusal. Your appeal should point out that omission.
You have 30 days to ask for the second review, which the site calls a Reconsideration. Someone new must decide it. It cannot be the person who said no, the officer who wrote the report, or that officer’s direct boss (the April 2026 rules). Your appeal must address the refusal directly. The rules say you “must specifically address the State’s previous factual or legal basis for the decision”. In plain words, quote the State’s reason and show why it is wrong. If you only say you disagree, the State can throw the appeal out without reading further.
So you write it like this:
Request for Reconsideration. Request [number], decided November 5, 2026.
The State’s reason. The decision says a carrier can lease or borrow a truck, so our cab cards do not prove the truck was not working for us.
Why that is wrong. We do not lease or borrow trucks. Our insurance schedule, attached to our first request on October 13, lists only our three trucks. Our ELD records, also attached then, show all three trucks were somewhere else on October 6. The list of evidence reviewed leaves out both papers. And the driver list you asked for on October 22 shows that the driver on the report never worked for us.
What we ask. Please review the papers already on file and remove this inspection from our record.
This appeal relies on evidence already submitted. It adds no new document. That keeps it at the second stage instead of sending it back to the start.
You file it on November 9. The State has 21 days to decide, until November 30. On November 24, the new reviewer agrees with you, and the inspection comes off your record. From the day you filed, it took 42 days.
If the answer had still been no, you would have had one more step. You would get 30 days to ask for the Final Review. It must be decided within 45 days by a senior person at the State, sometimes with advice from a panel or an outside party. No one who worked on the first two reviews can take part (the April 2026 rules). The same rules apply: answer the reasons, and add no new papers unless you are asked.
After that, it is over. The rules say “the State’s decision will be considered final by FMCSA after the Final Review is completed.” FMCSA can help the State read a rule, but it will not settle your dispute. There is no further appeal to FMCSA through this process. That is why your first request matters most. Each later review reviews the papers you sent at the start.
What if the State is late? Being late does not make you win. FMCSA said decisions “must be based on the validity of the claim”, not on how long they took (the April 2026 rules). In plain words, the State still has to decide if you are right. Instead, FMCSA will grade each State on the share of requests it decides on time. It plans to post those reports on the DataQs website once it has enough data. One more limit: these deadlines are for the States. If a federal inspector wrote your report, FMCSA says it is still weighing deadlines like these for its own reviews.
Chapter 05
What if my driver got a ticket for it?
If the ticket goes to court, the court’s decision determines how the violation is treated. If your driver is found not guilty, or the ticket is dismissed with no fine and no court costs, the violation comes off your scores. If the ticket is dismissed but someone pays a fine or court costs, the violation stays. If your driver pleads guilty to a lesser charge, the violation stays but counts at the lowest weight, 1. You send a certified copy of the court’s result through DataQs (FMCSA’s 2014 policy on court results).
A ticket changes the process. Consider a second example. Say that next spring one of your own drivers is stopped. The officer writes a violation on the inspection report and also hands over a ticket for following too closely. Your driver says it was wrong and wants to fight it in court. The court case can now affect the inspection violation. DataQs cannot decide the ticket. Only the court can.
So you wait. FMCSA says a request about a ticket can be held while the court case is open. It should go ahead once the court decides, but it should not stay open forever (the April 2026 rules). In practice, file once you have the result. The violation keeps counting while you wait, so an early court date helps you.
When the court decides, its result sets what happens to the violation. FMCSA’s policy spells it out in a table (FMCSA’s 2014 policy on court results).
| What the court decided | In your safety scores | In the driver’s work history report (PSP) |
|---|---|---|
| Not guilty | Removed | Removed |
| Dismissed, with no fine and no court costs paid | Removed | Removed |
| Dismissed, but a fine or court costs were paid | Stays | Stays |
| Guilty of a lesser charge | Stays, marked as a different charge, and counts at weight 1 | Stays, marked as a different charge |
The work history report, called PSP, is what other carriers check before they hire a driver. So the court result follows your driver too.
The third row is the trap. Many owners think “dismissed” means “gone”. It does not always. Under the federal definition, a conviction includes “the payment of a fine or court cost” (the federal definition). So a dismissal that still costs money counts as a conviction, and the violation stays. Say your driver’s lawyer comes back with a deal. The ticket is dismissed if your driver pays $150 in court costs. That sounds like a win. For your scores, it is a loss.
Not every fee is a court cost, though. FMCSA’s policy says a fee that everyone at that court pays, whatever the result, does not count. Neither does the fee for a certified copy of the court’s order, or your lawyer’s fee (the 2014 policy). But a “court cost” that is much bigger than usual, and works like a punishment, can count as a fine. So before your driver takes any deal, ask one question. Will anyone pay a fine or court costs? If yes, the violation stays.
Just paying the ticket is a conviction too, under the same definition. Payment gives you no favorable court decision to support removal, so the violation stays. So decide whether to fight before anyone pays. The costs of that choice are explained in our guide to fighting an unjust citation.
A guilty plea to a lesser charge is not a full win, but it helps. The violation stays, but it counts at weight 1, the lowest there is. It also loses the 2 extra points for being put out of service (the scoring manual). You still have to send the court result through DataQs to get that change. And be careful with “deferred” or “diversion” deals. A State may not use them to keep a CDL driver’s traffic conviction off the driver’s license record (the federal rule). If the license is the bigger worry, read what a ticket does to a CDL.
To have the court result recorded, you need proof of the decision. You need a certified copy from the court: the docket entry, the order of dismissal, or the finding of not guilty (the 2014 policy). Certified means the clerk has stamped or signed it as a true copy. A link to the result on the court’s official website also works. Then you file it in DataQs against the inspection report, just as you did in the first story.
Chapter 06
Is it worth it, and what has changed?
Yes, if the violation was recorded in error and is still recent. It counts three times as much in its first six months and drops out after 24 months (the scoring manual). If every stage runs to its last day, the whole process takes about five months. So file within days, not months. And know that the rules changed on September 13, 2026. Advice written before then describes a process that no longer exists (the April 2026 rules).
Go back to your first case. You won in 42 days. But what if the State had used all its time at every stage, and so had you (the April 2026 rules)? You filed on October 13, so the first answer would come on November 3. You could wait until December 3 to appeal, and the answer would come on December 24. You could wait until January 23, 2027 to ask for the final review, and its answer would come on March 9. That is 147 days, almost five months.
Now look at the violation’s age. Its first six months, when it counts three times over, end on April 6, 2027. So even the longest road ends just 28 days before that. Add one request for papers at each stage, at 14 days each, and the end moves to April 20. By then the violation has spent its heaviest months on your record.
Two lessons follow. First, file fast, and file complete. A request closed for missing proof has to be sent again, and the weeks you lost do not come back. Second, weigh the violation’s age. A wrong violation from six weeks ago may be worth taking through every stage. One from 20 months ago counts only once and drops out of your scores in four months, likely before a final review is decided. Fixing it still cleans the record, but it will not change your scores for long. Clean inspections help as well. Each one counts in the score math, so it can reduce the effect of existing violations (the scoring manual).
So what changed on September 13, 2026? Before, each State ran its own review in its own way and on its own clock. Now every State must offer three reviews by different people, with fixed deadlines. A refusal must name who decided and list what they read. The officer who wrote the violation cannot be the only one to say no at the first stage (the April 2026 rules).
It took three years to get here. FMCSA first asked for comments on an appeal process in September 2023. It proposed the new steps in July 2025, with 30 days for the final review. The California Highway Patrol and a national inspectors’ group said a panel could not meet that fast, so FMCSA made it 45. It published the final rules on April 16, 2026, and they took effect 150 days later (the April 2026 rules).
So some advice you will find is out of date. If you have heard that you can just file and see what the State says, that no longer works. Now a request with no proof can be closed without a review of the facts. Any guide that describes one review, with no set appeal and no deadlines, was written for the old way. And some advice was never right. “Dismissed” never meant “removed” if money was paid.
There are things we could not check. The DataQs website blocks automated checks. So we could not confirm that its new version went live on September 13, 2026, as the rules planned. For the same reason, we do not describe its screens or its list of reasons to pick from. We also could not confirm the exact delay before an approved correction appears in your safety scores. And there is no official success rate. FMCSA publishes how many requests are filed, not how many win. The success rates you may see quoted do not trace back to any FMCSA source. What decides your case is on this page: papers that show the record is wrong.
If you would rather hand this work to someone, we build the request, answer the State and write the appeals: here is what it costs.

FAQ
Frequently asked questions
Can you DataQ a warning, or only a citation?
You can dispute anything written as a violation on an inspection report. It does not matter if the officer gave a ticket, a warning or nothing at all. FMCSA counts violations on the report in your scores either way. A warning with no inspection report behind it leaves nothing on your record, so there is nothing to fix.
Is there a deadline for contesting a roadside inspection?
Yes. The State must take a request about an inspection for 3 years after the inspection, and about a crash for 5 years after the crash. But do not wait. A violation counts most in its first six months and stops counting after two years. A late request can fix the record and still do nothing for your scores.
What is the success rate of DataQs challenges?
There is no published official success rate. FMCSA publishes how many requests are filed each year. It does not publish how many win. The success rates you see quoted online do not come from FMCSA. What decides your case is whether your papers show the record is wrong.
Can FMCSA overturn my State’s decision?
No. The State that did the inspection decides your request, and the two appeals stay inside that same State. After the final review, the State’s answer is final. FMCSA sets the rules the States must follow, but it does not settle disputes about the facts of a case.
Can a driver file a DataQs request, or only the carrier?
Both can. DataQs is open to carriers, to drivers and to others. But the violation affects the carrier’s safety scores, and the carrier usually holds the papers that prove the mistake, like registrations, driver lists and payroll. So in most cases the carrier should file.
Should I pay the ticket before I dispute it in DataQs?
No. Paying a ticket counts as a conviction under federal rules, even if you only pay court costs. Payment does not give you a favorable court decision to support removal, so the violation stays on your record. Decide whether to fight the ticket first. DataQs can still fix a plain mistake on the inspection report.
Does DataQs cover a drug test or a Clearinghouse record?
No. DataQs only covers inspection and crash records. A drug or alcohol test result, an entry in the Drug and Alcohol Clearinghouse and your safety rating are all handled elsewhere. If the record you want to fix is not an inspection or a crash, DataQs is the wrong place.
