Unidentified Driving Records On ELDs: What They Are & How To Fix
You log in Monday morning and your ELD asks you to review two hours of driving from Saturday. You weren't anywhere near the truck on Saturday. That's an unidentified driving record, and it's one of the most common headaches in ELD compliance.
They're not hard to manage once you understand where they come from. Left alone, though, they pile up, trigger diagnostic warnings and give inspectors and auditors a reason to dig deeper. Here's what they are, what the rules require and how to keep them under control. For the wider rules on driving limits, see our hours of service guide and ELD mandate facts and compliance. Rules were checked against 49 CFR Part 395 and its Appendix A in October 2026.
What Is An Unidentified Driving Record?
An ELD automatically records driving whenever the truck moves above a low speed threshold. If no driver is logged in at the time, the ELD can't put that driving on anybody's log. It records it under an "unidentified driver" profile instead.
The ELD rule requires this. Driving time doesn't just disappear because nobody logged in.
What Causes Them
Most unidentified driving comes from a handful of everyday situations:
- A driver forgets to log in before pulling out.
- Yard moves by a mechanic, yard jockey or another employee who isn't logged in.
- Shop visits where a technician test drives the truck.
- A tablet or phone that disconnects from the ELD, so the driver's session drops while driving.
- Logging out too early at the end of a shift and then moving the truck.
- A shared truck where the next driver starts before logging in.
- Towing or ferrying where the engine runs and wheels turn.
Connection problems are worth special attention. If you see unidentified time on trips where you know a driver was logged in, check the Bluetooth connection, the app version and the tablet's power saving settings.
What The Rules Require
The driver's part
When a driver logs in, the ELD has to prompt them to review any unidentified driving records on that vehicle. The driver can accept records that belong to them, which moves the driving onto their log, or reject records that aren't theirs.
Only accept records that are truly yours. Accepting someone else's driving puts it on your hours and can cause false violations. Rejecting your own driving to save hours is falsification.
The carrier's part
Under 49 CFR 395.32, the motor carrier has to review unidentified driving records and either assign them to the right driver or annotate them to explain why they can't be assigned. The carrier also has to keep unidentified driving records for at least six months, along with the rest of its ELD records.
"Annotate" means a note that makes sense, like "yard move by mechanic J. Smith, not a CMV driver on duty" or "technician test drive at dealer." A note that just says "unknown" doesn't help much.
Why Inspectors Care
Unidentified driving is one of the first places someone looks if they suspect logs are being gamed. A pattern of unassigned driving on the same truck can look like a driver running off the clock. That's why it matters to clean these up quickly and keep good notes.
At roadside, the ELD's data transfer includes unidentified driving records for the vehicle. During compliance reviews and audits, investigators can look at how a carrier handles them over time.
The diagnostic indicator
The ELD technical rules include an "unidentified driving records" data diagnostic event. It's set when more than 30 minutes of unidentified driving builds up within a 24 hour period over the current day and the prior 7 days. When that happens, the ELD shows a diagnostic indicator. It clears once the unidentified time drops below that level. If you see that indicator often, you have a process problem.
How To Assign Or Annotate
The exact screens vary by ELD, but the workflow looks the same:
- Open the unidentified driving report in your fleet portal.
- Filter by truck and date. Look at location, time and distance.
- Match each event to a person. Use dispatch records, fuel receipts, gate logs and the schedule.
- Assign it to the right driver if it was CMV driving by a driver. The driver then has to accept the assignment on their device.
- Annotate it if it can't be assigned. Explain clearly and briefly what happened.
- Close it out and keep the record.
A driver who receives an assigned record and believes it's wrong can reject it. Talk it through rather than forcing it. Carrier edits need driver confirmation, and pressuring drivers into accepting false records is a separate violation.
Best Practices For Fleets
Review often
Weekly is the minimum. Daily is better for busy fleets. Small backlogs are easy. A three month pile is a project.
Give shop and yard staff their own login
If mechanics or yard staff regularly move trucks, set them up with logins so their movement is recorded under their names instead of as unidentified driving. Your ELD provider can explain the options. Some support a specific yard move status for drivers.
Train on login habits
Make logging in the first thing a driver does after starting a pre trip inspection. Make logging out the last thing after parking for the night.
Check for tech problems
If unidentified time shows up during trips with a logged in driver, it's often a disconnect. Update the app, check cables and turn off battery saving for the ELD app.
Use alerts
Many ELD portals can send an alert when unidentified driving is recorded. Turn it on so problems get handled the same day.
Keep a short annotation guide
Give your safety team a set of standard annotation phrases so notes are consistent and explain what happened.
Unidentified Driving Versus Personal Conveyance And Yard Moves
These get confused a lot:
| Status | Who | What it means |
|---|---|---|
| Unidentified driving | No driver logged in | Driving recorded with no driver attached |
| Yard moves | A logged in driver | On duty not driving movement in a yard, when the carrier allows it |
| Personal conveyance | A logged in driver | Off duty personal use of the truck, under FMCSA guidance |
Yard moves and personal conveyance are statuses a logged in driver selects. They're not a way to clean up unidentified driving after the fact.
A Simple Weekly Routine
Here's a routine a small fleet can actually stick to:
- Monday morning, open the unidentified driving report for the past week.
- Assign anything that clearly belongs to a driver.
- Annotate yard moves, shop time and anything that can't be matched.
- Note the trucks with repeat issues and check their hardware.
- Remind drivers with repeat login misses.
It takes ten minutes for a few trucks. That's a lot cheaper than explaining a messy record during a compliance review.
Frequently Asked Questions
What is an unidentified driving record?
Driving that the ELD recorded while no driver was logged in. The ELD stores it under an unidentified driver profile.
Do I have to accept unidentified driving?
Only if it's yours. Drivers should accept records that belong to them and reject the rest.
What does the carrier have to do?
Under 49 CFR 395.32, review unidentified driving records and either assign them to a driver or annotate why they can't be assigned, and keep them for at least six months.
What triggers the unidentified driving diagnostic?
More than 30 minutes of unidentified driving within a 24 hour period over the current day and the prior 7 days.
Can a mechanic's test drive cause one?
Yes. Any vehicle movement above the ELD's driving threshold with no one logged in can create an unidentified driving record.
