How do I submit and track a DataQ challenge?

Chapter 01

How do I get into DataQs as a carrier?

As a carrier, you get into DataQs through the FMCSA Portal, and you sign in to the Portal with Login.gov. Login.gov is the government’s sign-in service. It asks for a second check, such as a code sent to your phone. Your Portal account then needs the “DataQs Secure Access” role for your DOT number. Once the role is approved, select DataQs from the Portal’s list of systems and click Go (FMCSA’s DataQs help pages). Drivers and other people sign up on the DataQs site itself, also through Login.gov.

Consider this example. Say you run three trucks. One Monday night in October 2026, you look at your safety record and find an inspection from October 6 that is not yours. The VIN, the plate and the driver on it belong to someone else. Our main guide to DataQs explains what proof to gather and how the State decides. This page is about the website itself: getting in, filing, and following the request to its answer.

You already have a Portal account, because you used it for your last MCS-150 update. Since January 2025, that update is done in the Portal (FMCSA’s Portal guide). You sign in at portal.fmcsa.dot.gov with Login.gov. Use the same email address for Login.gov and for the Portal. The Portal’s sign-in page says that is how your Login.gov account gets linked to your Portal roles.

But when you look under “Available FMCSA Systems”, DataQs is not there. Your account does not have the role yet. You need to request that role. FMCSA’s help page gives these steps (FMCSA’s DataQs help pages):

1. In the Portal, click “Account Management” and choose “My Profile”.
2. Open the “Portal Roles/USDOT#” tab and pick your DOT number.
3. Under Available Roles, select “DataQs Secure Access” and click Add Role.
4. Type a reason, such as “Need to submit a Request for Data Review.”
5. Click “Update Profile”.

Every DOT number has one company official in the Portal, and that person approves new roles (FMCSA’s Portal guide). In your company, that is you. The official sets up the Portal account once, with the company’s USDOT PIN. That is a code FMCSA sends by email, text or mail, and you ask for it on the SAFER website. Because you are the official, the help page says to log out and log back in. The DataQs link then shows up under Available FMCSA Systems. If it does not, try again after an hour. You select DataQs, click Go, and you are in.

If you had no Portal account, you would make one at the same address. You sign in with Login.gov and enter your DOT number and PIN. Then you take the “Portal Company Official” role, and the system approves that account at once. While you sign up, you can ask for DataQs Secure Access in the same step (FMCSA’s guide to registering for DataQs).

With this role, you can follow all requests about your company. You can see every DataQs request about your DOT number, even ones someone else filed. You also get an email when anything is posted on them, or when their status changes (FMCSA’s DataQs help pages). Every user can file requests, see their status, read the papers attached and add more.

Who else can file? Anyone may open a free DataQs account and file a request, and that includes your drivers. A driver with a CDL who is not an owner-operator signs up as a “Driver”. A law firm, an insurance company or a service company signs up as “Public/Industry”. Both sign in through Login.gov on the DataQs site. An owner-operator with a CDL signs up as a motor carrier, through the Portal. And an office worker or a safety company can join your Portal account as an “Associate of a Company”. They can ask for the DataQs role for your DOT number, and you approve it (FMCSA’s Portal guide).

Some owners opened a DataQs account years ago, with a username and password. If you have one of those accounts, you now sign in through Login.gov, with the same email address as that old account. DataQs now requires that second check at sign-in (the DataQs home page). If you have more than one DataQs account, the help page shows how to merge them, so all your requests sit in one place. And if something will not work, DataQs has a help line at (877) 688 2984, option 1. Portal problems go to (800) 832 5660. Once you have access, find the inspection you want to challenge.

Chapter 02

How do I find the inspection and choose a request type?

You start a new request and say it is about an inspection. Then you search for the report by the State where the stop happened and the report number. Next you pick the request type that names your mistake. For an inspection that is not yours at all, choose the request type “Company and/or USDOT Number is listed incorrectly on the inspection report” (FMCSA’s DataQs help pages). The report number sits in the top right corner of the inspection report. It is not the ticket number.

Before you click anything, you write down the report number. You can find it on your record on FMCSA’s safety score website, or in the Portal. The Portal shows new inspections sooner. It updates every night, while the safety score site updates once a month. The number usually has 10 digits. Some States use 12 characters, starting with the State’s two letters. Leave those letters out when you type it (FMCSA’s DataQs help pages).

Then you start. The help page says the DataQs home page has a “Start a New Request” button. On My DataQs, you can also pick a request category under “Start a New Request” and click “Start Request”. The screens that follow change a little with the kind of request. For an inspection, a crash, an investigation or an audit, DataQs makes you find the record first.

In the search, use the State where the inspection took place, not the State where your company is based. Start with just the State and one more field, like the report number. Add more only if you get too many results. If the inspection is very new, it may not be in FMCSA’s system yet. Then the help page says to choose “I do not see my report on the list”, pick a report type and click “Next”. Choosing the right State also matters for routing. DataQs sends your request to the office of the State you name. Name the wrong one, and your request waits until someone forwards it to the right office (FMCSA’s DataQs help pages).

Next you choose the request type. FMCSA’s list, last updated on March 17, 2026, has seven choices for an inspection (FMCSA’s DataQs help pages). Each one fits a different mistake. In this example, the entire inspection belongs to another carrier: the truck, plate and driver are all wrong. Choose the option for an inspection assigned to the wrong company. On the list, it reads “Inspection—Company and/or USDOT Number is listed incorrectly on the inspection report”.

Other owners pick other types. A wrong violation, or one written twice, goes under the choice that starts “Inspection—Violation is incorrect, listed multiple times”. A wrong driver name or license number has its own choice. A wrong VIN, plate or place, on an inspection that really is yours, goes under “Inspection report contains incorrect information”. The same inspection listed twice is a “Duplicate”. Be careful with “Inspection—Did not receive a copy or lost the inspection”. It only asks for a copy of the report, and it fixes nothing. The help page also explains a limit. A violation you fixed after the stop is not a wrong violation, so it stays on the record.

If your problem is a crash, the choices and the papers are different. We cover them in our guide to crash records in DataQs. If a ticket came with the violation and a court has decided it, you send the court’s result. An older help answer, from 2023, names a choice for that: “Citation associated with violation on an inspection”. The newer list from March 2026 does not show it, so look for it on your screen. What to send is in our main guide.

After the type, you enter the request details: what is wrong, why, and what you want fixed. The help pages do not show that screen, so we cannot tell you its exact boxes. What to write, with a sample, is in our main guide. Keep the explanation short and refer to your supporting documents. You will attach those next.

Chapter 03

How do I attach documents and confirm the request was sent?

You can upload your papers while you fill in the request, or later on the request’s Correspondence tab. FMCSA asks you to send them as soon as you can. The request has been submitted when DataQs gives it an ID number and it shows up on My DataQs with the status “New”. If it says “Saved Draft”, it has not been sent. You can save a copy with the request’s “Download PDF” button (FMCSA’s DataQs help pages).

On October 13, you file. You add your papers as you go: the cab cards for your three trucks, your insurance schedule and your ELD records for October 6. FMCSA’s help page, updated on August 19, 2026, says documents “may be uploaded while entering the request or later” (FMCSA’s DataQs help pages). To add documents later, use the request’s own page. Open it and click the Correspondence tab. Under “Add Response/Documentation”, tick “Check box to add document(s)”. Then follow the steps shown under “Add Documentation”.

What kinds of files can you send, and how big? FMCSA’s help pages do not say, so we will not guess. If the site will not take a file, call the DataQs help line. You can also fax papers in. The Correspondence tab shows how, and faxed pages show up in the request’s “Document List”. FMCSA changed the DataQs fax number in August 2026, so take it from the tab, not from an old guide.

Once the request is complete, submit it. The help page says that when a request is loaded, “an acknowledgement is generated”. DataQs then sends it to the State’s office and emails the people there. DataQs has now given your request an ID number. Write it down. It is the number you will search by later, and the one to give anyone who asks about your case. We could not see what the confirmation screen looks like, or whether the acknowledgement comes to you by email. The help pages do not say.

Check that the State received the request. Go to My DataQs and look at the table under “Monitor an Existing Request”. Your request should be there, with today’s date and the status “New”. New means the State has not looked at it yet (FMCSA’s DataQs help pages). If the status reads “Saved Draft”, it has not been sent to the State. To send it, open the request and go to the Correspondence tab. Add your response and your papers, and click Submit. The help page says it is then “submitted to the appropriate agency and is no longer a draft”.

Last, keep a copy. The request’s page has a “Download PDF” button that saves the whole request. Keep it with your papers. If the answer takes months, you will be glad you did. While waiting for an answer, check for messages and changes in status.

Chapter 04

How do I check on my request and answer the State?

Log in, go to My DataQs, and find your request under “Monitor an Existing Request”. Search by its ID number or its status, and click the ID number to open it. DataQs also emails you when something is posted or the status changes (FMCSA’s DataQs help pages). When the State asks for more information, the status turns to “Open—Pending Requestor Response”, which means it is waiting for you. You answer on the request’s Correspondence tab. Under the April 2026 rules, you have 14 days.

The status tells you what is happening with your request. For the first days, the status stays “New”. When the State starts on it, it changes to “Open—In Review”. On October 22, you get an email. The status now reads “Open—Pending Requestor Response”. The State wants a list of the drivers you had on October 6.

You answer the same way you added papers. Open the request and click the Correspondence tab. Type a short reply, tick the box to add documents, upload the driver list and click Submit. You do it on October 24. The status changes to “Open—Pending Agency Review”. That means your answer is waiting for the State (FMCSA’s DataQs help pages).

The help page gives an outdated deadline next to “Open—Pending Requestor Response”. That answer, from 2023, says you “may have up to 60 calendar days to respond”. Under the April 2026 rules, you get 14 days. If you do not answer, your request can be closed as “Closed—No Requestor Response” (the April 2026 rules). How that clock works, and what happens if you miss it, is in our main guide.

You may see other statuses on the way. “Open—Pending Officer Comments” means the State asked the officer who did the inspection. “Forwarded to Another Office for Resolution” means another office must help, or the request belongs to it. Neither status calls for a response from you. If you have a question about your request, call the office handling it. Its contact details are on the request’s page (FMCSA’s DataQs help pages). If your request is missing from the table, check that you logged in with the account you filed from. The help page warns that accounts are separate, even with the same email and name.

Keep your Portal account active while you wait. Log in at least every 90 days. The Portal disables an account after 90 days without use, and archives it after 12 months (FMCSA’s Portal guide). A request with appeals can run for months, so this matters.

On November 5, the status changes to “Closed—No Data Correction Made”. That means the State reviewed the request and declined to change the record. What that answer must tell you, and how to argue for a second review, is in our main guide. Had the State said yes, the status would read “Closed—Data Correction Made”.

How do you ask for that second review on the website? We could not check. An old help answer, from 2023, describes a box to tick: “I would like to have this request reviewed again”. It says you could do that only once. That was the old way. The April 2026 rules give you two further reviews (the April 2026 rules). The new site was meant to support them, but we could not see how it does.

When a fix is finally made, at the first review or a later one, it does not show everywhere at once. The Portal’s Company Activity section shows your company’s records most fully. FMCSA’s safety score site and the driver history report called PSP update once a month. FMCSA takes a snapshot on the third or last Friday of the month, and processing takes about 10 days (FMCSA’s DataQs help pages).

Last, know where these steps come from and how old they are. We read FMCSA’s DataQs help pages as saved on September 8, 2026, and the DataQs home page as saved on August 11, 2026. Each help answer has its own date, from September 2023 to August 2026. The answers about signing in with Login.gov date from December 2024. We also read FMCSA’s guide to registering for DataQs, from January 2024, and its Portal guide, from March 2025. The April 2026 rules planned a new version of DataQs for September 13, 2026. It was to bring new ways to notify the person who filed and the reviewers (the April 2026 rules). We could not open the site after that date, so some screens may look different now. And some older help answers are already out of date. They give you 60 days to answer, one reopening, and the State a goal of 10 business days. The April 2026 rules replaced all three.

If you would rather hand this to someone, we can file it, watch it and answer the State for you: here is what it costs.
