Telematics and ELD Data: The Operating History You Already Have
Telematics and ELD data enter a truck financing file as evidence about the vehicle you are buying: the tractor or the straight truck itself, not charging equipment and not yard electrical work. You bought the device to satisfy a federal rule. It has been building a continuous, timestamped record of your operation ever since.
A carrier two years into its authority has thin tax returns and a short credit file. Being told you cannot document an operation that plainly exists is strange, when a box wired into the dash has logged every mile of it.
What follows: what the record contains, how far back it reaches, what it cannot prove, and how to put six months of it on one page.
> Key Takeaways
> - Motor carriers must retain ELD records of duty status and supporting documents for six months, plus a backup copy on a device separate from where the original data sits (FMCSA, 49 CFR 395.8(k)(1)).
> - A compliant ELD captures engine power status, vehicle motion, miles driven, engine hours and geo-location automatically, without anyone deciding to log it (FMCSA, 49 CFR Part 395 Subpart B, Appendix A).
> - Six months is a floor, not a filing cabinet. A carrier three years in who has never exported anything owns a six-month memory of a three-year business.

What does your ELD actually record?
A compliant ELD does not wait for anyone to write anything down. Under FMCSA's functional specifications, the device automatically captures engine power status, vehicle motion status, miles driven, engine hours and geo-location, and switches itself into driving mode once the vehicle crosses the motion threshold (FMCSA, 49 CFR Part 395 Subpart B, Appendix A).
Those fields were specified to police hours of service. Read them a second time and they describe a business.
Engine hours against odometer miles shows how much of the clock was spent moving rather than idling. Drive time against total on-duty time shows how much of a paid day was productive. Start and end locations per day give you the shape of your lanes without anyone writing a lane report.

Telematics platforms stack more on top: idle time, fault codes, fuel burn, hard-braking events. That layer is vendor-specific. The ELD floor underneath it is standardized, and every compliant device produces the same defined standard output file. What you hand over is a regulated format, not a screenshot of somebody's dashboard.
Why does operating history matter more than projections?
In June 2025, the American Trucking Associations counted almost 580,000 active motor carriers registered with FMCSA, with 91.5% of them running 10 or fewer trucks (ATA, June 2025). At that size there is no CFO and no audited statement, so measured operating data is often the strongest documentation an applicant can produce.
A thin file has a recognizable shape. Short authority history, one or two tax years, personal credit doing most of the work, and a freight plan written in the future tense.
Here is the distinction that matters. A freight plan is an argument. A dispatch log is evidence. One says what you intend to haul, the other says what you already hauled, on which days, over how many miles.
None of this is a requirement anyone hands you. It is the difference between what you can show and what you can assert. The pillar guide to truck fleet financing covers how a whole file gets assembled, and what sits next to the score on a carrier application covers the credit half.
Which three numbers should you pull from the record?
Three measures come straight out of the export and describe the business rather than the driver: utilization, deadhead share, and uptime. All three are computed from fields a compliant ELD already captures automatically (FMCSA, 49 CFR Part 395 Subpart B, Appendix A), which means the data exists whether or not anyone has looked at it.
Utilization. Annual miles per power unit and days dispatched per month. Two trucks with identical odometers and very different dispatch-day counts are not the same operation.
Deadhead share. Loaded miles divided by total miles, computed from your own record instead of an industry average. Yours is the interesting number. For context on when empty miles get expensive, reading the freight cycle before you buy covers the cycle analysis.
Uptime. Engine hours and the gaps between dispatches, cross-read against maintenance records. Downtime shows up in the data before it shows up in an inspection, because a truck that stops earning stops logging.
For scale, ATRI measured the industry-average cost to operate a truck at a record $2.336 per mile in 2025, up 3.4%, with non-fuel costs at $1.854 (ATRI, July 2026). A yardstick, not your number.
How far back does your ELD record actually go?
Farther than you think and shorter than you need. Motor carriers must retain ELD records of duty status and supporting documents for six months, and must keep a backup copy on a device separate from where the original data is stored (FMCSA, 49 CFR 395.8(k)(1)). Six months is a floor, not a filing cabinet.
The regulation secures a rolling six-month window. Everything beyond it is decided by your provider's retention policy, your subscription status, and whether your device history survived a hardware swap. A carrier three years into an operation who has never exported anything has a six-month memory of a three-year-old business.
The window closes behind you at the same speed you move forward.
The fix costs an afternoon a quarter. Export the standard output file every three months and store it somewhere you control.
The record is also yours by rule. If a driver cannot pull their own original records off the device, the motor carrier must provide access on request across the retention period (FMCSA, 49 CFR 395.30(f)).

What happens when your ELD provider comes off the registered list?
FMCSA removes self-certified devices from the registered ELD list when the companies behind them fail to meet the minimum requirements, and carriers get up to 60 days to replace a revoked device with a compliant one (FMCSA, January 2026). Removals have arrived in repeated batches through 2025 and 2026.
The compliance consequence is obvious. Keep running a revoked device past the window and you are operating without an ELD, with drivers subject to being placed out of service.
The records consequence is the one operators miss. Your history has been living in that provider's portal. When you migrate, the subscription ends and whatever you never pulled down goes with it. That is the most common way a gap appears in an otherwise continuous record.
So the order matters. Export first, then migrate.

FMCSA publishes both the registered and the revoked device lists, which is where to check a provider before you sign. That check belongs with your FMCSA registration record.
What does the ELD not prove?
It proves the truck moved. It does not prove anyone paid you. The record captures miles, hours and position under FMCSA's functional specifications (FMCSA, 49 CFR Part 395 Subpart B, Appendix A), and says nothing about rate, settlement, deduction or collection.
Anyone selling you a device will not say that. It is still true.
The record needs company: rate confirmations and settlement statements covering the same date range, business bank statements, maintenance and repair records, insurance certificates, registration and filings. Side by side, each one supports the others.
From the credit side, the difference between two applications is usually visible in the first minute. One arrives with projections and adjectives. The other arrives with measured miles, dispatch days, and deposits that line up against them. That is an observation about what applicants bring, not a rule about how anything gets decided.
Build the reconciliation habit before anyone asks. If your dispatch days and your deposits do not agree across the same six months, find out why. Slow-paying customers, unbilled loads and unresolved unassigned driving time all surface there.
Unassigned driving time deserves its own line. Motor carriers must either annotate unidentified records with an explanation or assign them to the right driver (FMCSA, 49 CFR 395.32(c)). Unresolved blocks read as either sloppy record-keeping or undisclosed drivers. For the rest of the folder, the documents a new carrier puts together runs through the list.
How do you turn six months of data into a one-page operating summary?
One page, eight fields, each with the record it came from, built from the six months the rule already makes you keep (FMCSA, 49 CFR 395.8(k)(1)). Nobody is going to read a raw export, and handing over an unstructured file transfers the work of interpreting your business to someone who has never seen it.
1. Reporting period and number of power units. ELD export.
2. Total miles and loaded miles per unit. ELD export.
3. Days dispatched per month. ELD export.
4. Deadhead share. Calculated. Show the formula: one minus loaded miles over total miles.
5. Days out of service and the reason for each. Maintenance records plus engine-hour gaps.
6. Top three lanes or customers by revenue share. Settlement statements.
7. Gross revenue for the same period. Settlements reconciled to bank deposits.
8. Unassigned driving time, resolved and unresolved. ELD export.
Attach the underlying export behind the page. Every number should trace back to a named record in one step.

Put the bad months on the page too. A quarter that dropped because a transmission went out, annotated with the repair invoice, is stronger than a quarter quietly removed.
The artifact carries forward too. When the record on unit one supports the case for unit two, financing a second truck starts from a page that already exists.
What if your operation is exempt from the ELD rule?
Plenty of working operations run no ELD at all. Drivers using the short-haul exception operate within a 150 air-mile radius of the normal work reporting location and are released from work within 14 consecutive hours (49 CFR 395.1(e)(1)). Pre-2000 model year engines and driveaway-towaway moves also sit outside the requirement.
Exempt does not mean undocumented. The substitute records are already in the business: GPS or routing exports from a delivery platform, dispatch software reports, fuel card statements, dated odometer photos, and customer route contracts.
Run the same three numbers through them. Utilization, deadhead share and uptime do not care which format produced the data. If you run short-haul and last-mile operations, that is usually where your version of the file lives.

{ question: "How long do carriers have to keep ELD records?", answer: "Six months. Motor carriers must retain ELD records of duty status and supporting documents for six months, and must keep a backup copy on a device separate from where the original data is stored (FMCSA, 49 CFR 395.8(k)(1))." }, { question: "Can telematics data help support a truck financing application?", answer: "It is evidence of utilization, deadhead share and uptime that a newer carrier often cannot document any other way. It works alongside settlement statements, bank records and filings rather than in place of them. Every application is subject to approval and eligibility." }, { question: "What data does an ELD record automatically?", answer: "Engine power status, vehicle motion status, miles driven, engine hours and geo-location, captured without anyone choosing to log them, per FMCSA's functional specifications in Appendix A to Subpart B of 49 CFR Part 395." }, { question: "What if my trucks are ELD exempt?", answer: "Short-haul drivers running within a 150 air-mile radius and released within 14 consecutive hours, pre-2000 model year engines and driveaway-towaway moves sit outside the rule (49 CFR 395.1(e)(1)). Dispatch software, GPS and fuel-card records cover the same ground." } ]} />The record you already keep
Your compliance device has been doing documentary work the whole time. The question is whether you collect it.
- Six months is a retention floor, not an archive, and it closes behind you.
- Export the standard output file quarterly and store it where you control it.
- Utilization, deadhead share and uptime describe the business, not the driver.
- The ELD proves movement. Settlements and bank records prove revenue. Bring both.
- One page with eight traceable fields beats a raw file every time.
Financing a truck is subject to approval and eligibility, terms are flexible and sized to the equipment and the operation, and Eos Loan charges no dealer fee. Most of what you bring is already inside a device you have been paying for since your authority went live.
