How do I fix unassigned driving on my ELD?

Chapter 01

What is unassigned driving, and why is it my job?

Unassigned driving is time when a truck moved while nobody was logged in to its ELD. The ELD records that driving under one account called “Unidentified Driver”. FMCSA calls these unidentified driving records. Drivers and ELD screens usually say unassigned driving time. The rule makes you, the carrier, responsible for reviewing those records. You must make sure each record is checked. Then you either note why it is unassigned, or give it to the right driver (the rule on driving with no login).

Here is how that looks in real life. Say you run five trucks. Every Monday you open your ELD provider’s website, the back office where you see all your trucks at once. On Monday, November 2, 2026, three trips sit under “Unidentified Driver”. Truck 2 moved for 26 minutes on Tuesday, October 27, and covered 14 miles. Truck 4 moved for 38 minutes early on Thursday, October 29, and covered 24 miles. Truck 5 moved three times on Saturday, October 31, for 9 minutes in all.

How did these trips get there? An ELD starts recording driving by itself as soon as the truck moves. If nobody has logged in, it shows a warning to stop and log in. It keeps recording the driving under the unidentified account anyway (the ELD technical rules). Each record carries the date, the time, the place, the miles and the engine hours (the rule on what the ELD records). The next driver who logs in on that truck gets a warning about new unassigned driving time. He must claim any trip that is his, or say that it is not his (the rule on driving with no login).

Truck 4’s trip also triggered a warning. When more than 30 minutes of driving in one day sits under the unidentified account, the ELD records a warning called a data diagnostic event. Its light stays on for every driver on that ELD, for that day and the next 7 days. It can go off sooner. That happens once such driving on that ELD over the last 8 days is down to 15 minutes or less (the ELD technical rules). This warning is about the records, not a broken device. If the ELD itself stops working, read what to do when your ELD malfunctions.

Other people see these trips too. At a roadside inspection, the ELD shows the officer the unidentified records for that day and the 7 days before it. They come as a separate report, next to the driver’s own log (the ELD technical rules). What the driver does during that stop is in what to do when your truck is pulled over. In an inspection, an audit or an investigation, you must make them available too. They must cover the same days as the ELD records you are asked for (the rule on driving with no login). A trip left under “Unidentified Driver” may be driving time missing from someone’s log. The rules make both the driver and the carrier responsible for accurate ELD records (the rule on ELD edits). And no driver or carrier may make a false report about duty status (the logbook rule).

That can cost money. As of September 2026, a required record that is incomplete, inaccurate or false can cost $1,584 a day, up to $15,846. Knowingly faking a log to hide another violation can cost up to $15,846 (FMCSA’s penalty table). These amounts come from the inflation update of December 30, 2024, and we found no 2026 update as of September 22, 2026 (the 2025 update). How a fine case works is in how to respond to an FMCSA enforcement notice.

When must you finish the review? The rule sets no deadline. FMCSA said so itself in 2015, when it wrote the ELD rule. It “does not place limits on when an annotation or correction may be made” (FMCSA’s 2015 ELD rule). But a trip from the past week shows up if that truck is inspected. And after a month, nobody remembers who drove. A weekly check, like yours, keeps each trip fresh enough to explain.

Chapter 02

How do I find out who drove the truck?

Start with what the ELD recorded for each trip. That is the date, the times, the place, the miles and the engine hours (the rule on what the ELD records). Then match it against your own papers for that day. Look at dispatch records, bills of lading, fuel and toll receipts, repair orders and the driver’s own log. Then ask the people who had the keys, and write down what they tell you.

Take truck 2 first. Its trip starts at 3:10 in the afternoon, near the repair shop where the truck was having its brakes done. The shop’s work order lists a road test after the brake job. So the shop’s mechanic drove it. He is not your driver, and he never logged in, because he has no account on your ELD.

Truck 5 is next. Its three moves on Saturday all stayed inside your fenced yard, and together they cover less than a mile. Sam, the helper who parks and washes your trucks, moved it to make room for a trailer delivery. He does not drive on public roads, and he has no ELD login either.

Truck 4 is the one that matters most. Its trip starts at 5:40 in the morning at your yard and ends at 6:18 at a truck stop 24 miles away. Ruslan drives truck 4. His own log for October 29 begins at 6:25, when he logged in at that truck stop. Your fuel card report shows a purchase for truck 4 there at 6:21. And his load was due for pickup at 7:30. You call him. He admits he forgot to log in and drove off with the warning showing. When the ELD asked him about the unassigned trip at login, he did not claim it.

Keep the papers you used. The rules list the supporting documents a carrier must keep to check its logs. They include bills of lading, dispatch records and expense receipts, such as fuel receipts. Messages sent through your fleet system and payroll records count too (the rule on supporting documents). You need not keep more than 8 for one driver’s day. Each should show the driver or the truck, the date, the place and the time. You must keep them so they can be matched to the log, and nobody may change them. The shop’s work order and a short written note from Sam are not on that list. Keep them with the trip anyway, because they prove your note.

What if you cannot find out who drove? The rule does not say what counts as a good enough explanation. So write down what you checked and what you found, and keep the papers. Then find out how someone could move that truck without logging in, and fix it.

Chapter 03

Should I assign the trip or explain it?

Assign the trip when one of your drivers drove it, because that time belongs in his hours. Explain it with a note when the person who moved the truck is not your driver. A mechanic on a road test is one example, and a helper moving trucks inside your yard is another. The rule gives you only those two choices (the rule on driving with no login). Deleting the trip is not one of them. You may not erase the original ELD record (the rule on ELD edits).

So trucks 2 and 5 get notes. In the back office, you open each trip and type the reason. The rules call this note an annotation. Keep it short and specific, so a stranger could check it. Yours could read like this.

Truck 2, October 27, 3:10 in the afternoon, 14 miles. Road test by the mechanic at the repair shop after a brake job. He is not one of our drivers. The shop’s work order is in our files.

Truck 5, October 31, three moves, 9 minutes. Moved inside our fenced yard by our yard helper to make room for a delivery. He does not drive on public roads. His written note is in our files.

Truck 4 is different. Ruslan drove it, so the 38 minutes are his driving time, and they belong in his log for October 29. You will send the trip to him in the next step.

Here is the trap. Some owners write “yard move” or “personal conveyance” on a trip like Ruslan’s to make it go away. Those are real categories on an ELD, but they do not work that way. You, the carrier, decide which drivers may use them. The driver must pick one on the ELD before the truck moves. He turns it off when that move ends (the rule on special driving categories). While it is on, a yard move is recorded as on duty but not driving, and personal conveyance as off duty. A trip made with nobody logged in had none of that. It was recorded as driving, and the ELD cannot shorten driving time it recorded (the ELD technical rules). FMCSA put it plainly in 2015. The rules “do not allow driving statuses, including off-duty driving, to be edited to say they are non-driving time” (FMCSA’s 2015 ELD rule). We found no rule that lets you relabel a trip afterwards.

Even a real personal trip has limits. FMCSA’s 2018 guidance lets a driver log personal conveyance as off duty in one case only. He must be “relieved from work and all responsibility for performing work” (FMCSA’s 2018 guidance on personal conveyance). Moving the truck closer to the next load does not count. Neither does taking it to a shop for maintenance. A carrier may also limit personal conveyance or ban it. That guidance said it would expire by June 7, 2023, unless FMCSA renewed it. We found no renewal in the Federal Register, and FMCSA’s website blocks our tools, so we could not check whether it still stands.

Now fix the cause, so the same trips do not come back. You, the carrier, manage the ELD accounts, and you must make drivers log in with their own details (the carrier’s ELD rule). FMCSA wrote in 2015 that any employee who moves a truck can have a login of his own, even for moves inside the yard. It did not expect this to add much work (FMCSA’s 2015 ELD rule). So ask your ELD provider to set up an account for Sam. Do you drive a truck yourself? Then FMCSA’s answer in 2015 was one account as a driver and a separate one for office work.

Chapter 04

How does the driver accept my edit, and what can I not change?

You send the change, and the driver decides. The rule says any edit requested by someone other than the driver needs the driver’s electronic confirmation or rejection. He then certifies that day’s log again and sends it back (the rule on ELD edits). For changes to his own log, you may ask only after he has submitted it, which he must do within 13 days (the logbook rule). The ELD keeps the original record either way.

On Tuesday, November 3, you open the truck 4 trip in the back office and assign it to Ruslan. Every provider’s screens look different, and we cannot show you yours. But the rule is the same for all of them: he must confirm or reject the trip himself. On Wednesday morning, November 4, he logs in and sees it. He accepts it. His log for October 29 now shows 38 minutes of driving, from 5:40 to 6:18. He must then certify the day again (the rule on ELD edits). He taps “Agree” under a statement that his log for that day is “true and correct”. With the trip assigned, the warning light on truck 4 can go off too.

Those 38 minutes are real driving time. They may start his working day earlier than his log showed, so look at his hours for that day again. The hours limits themselves are a subject for another page.

Nothing is lost in this edit. The ELD must keep the original record even after an allowed edit. It marks each record as active or changed, and shows where it came from. It may come from the ELD itself or from the driver. It may also be a change someone else asked for, or a trip taken over from the unidentified account (the ELD technical rules). An officer who reads the ELD’s report sees those marks and the notes. The rule also forbids you to “alter or erase” the original hours data, or to let anyone else do it (the rule on ELD edits). FMCSA explained why in 2015. Officials must be able to “compare the chronology with the annotations and corrections, and supporting documents” (FMCSA’s 2015 ELD rule). In plain words, they read the first version, then each change and the reason, and check it all against your papers.

Some records cannot be edited at all. The ELD will not let anyone change a login or logout, or the engine turning on or off. The same goes for the automatic hourly records made while driving, and for malfunction and diagnostic records. Driving time the ELD recorded cannot be shortened or moved to another driver’s name (the ELD technical rules). There are two exceptions. One is giving an unidentified trip to the driver who drove it, as you just did. The other is a team. Say the ELD put the driving on the wrong one of two team drivers. If each log shows the other as his partner, the time can move between them. Both must confirm it. Every change or addition that a driver or your office makes must carry a note explaining it (the rule on ELD edits). So editing ELD logs is allowed, but it always leaves a trail.

What if Ruslan had rejected it? The ELD would mark your request as rejected, and the trip would stay under “Unidentified Driver” (the ELD technical rules). You cannot accept it for him. The rule says “a motor carrier may not coerce a driver to make a false certification” (the rule on ELD edits). In plain words, you may not pressure him into signing a log he says is wrong. But your duty to explain the trip does not go away. Write a note on it that says what your papers show. List the fuel purchase at 6:21 and the pickup at 7:30, and say that the driver declined the trip. Keep those papers with it. Then talk with him, because both of you answer for accurate logs.

Last, keep everything. Keep the unidentified driving records for each ELD for at least 6 months. The clock starts on the day you receive them (the rule on driving with no login). Keep the logs and supporting documents for 6 months too (the logbook rule). And keep a backup copy of your ELD records for 6 months. It must sit on a device separate from the originals (the carrier’s ELD rule). So the papers for October 29 stay until at least the end of April 2027. When an auditor asks for your hours records for some months, you must make the unidentified trips for those months available too. How to upload files for an audit is in our guide to the offsite safety audit.

What has changed? The two rules at the heart of this page, on unassigned driving and on edits, have not changed since FMCSA published them in December 2015. They have applied to every ELD in use since December 18, 2017 (the rule on when ELD rules apply). So older guides on this subject are mostly still right. Here is what we could not check. We found no FMCSA document that says how an auditor or investigator weighs these trips. FMCSA’s safety audit guide, in its 2018 revision, explains how to send your ELD file but says nothing about them (FMCSA’s safety audit guide). FMCSA’s own ELD pages block our tools, so we could not read them either.
