How ELD and driver logbook records prove fatigue after a North Carolina truck accident
August 2026: first published.
Driver logs and ELD records show driving time the device captured on its own next to duty status the driver entered by hand, which is how a violation of 49 CFR 395.3 is established. Supporting documents kept under 49 CFR 395.11 test the entered hours.
The carrier knows what the log says before anyone else does. The truck is theirs and the recording device is theirs. The retention clock started running the day the record came in and nobody at the carrier is required to mention that it is running.
Fatigue is not proved by saying a driver looked tired. The argument starts with hours. Those hours are written down in more than one place and not every one of those places belongs to the trucking company. A violation of the hours rules is not the same thing as proof that fatigue caused a wreck. It is where the question starts.
At a glance
- Under 49 CFR 395.3, a property-carrying driver in interstate commerce may drive up to 11 hours after 10 consecutive hours off duty and may not drive after the 14th consecutive hour on duty.
- North Carolina intrastate carriers run on different limits. Under 14B NCAC 07C .0101, an intrastate driver may not drive more than 12 hours following 8 consecutive hours off duty, or after 16 hours on duty.
- An electronic logging device records location at 60-minute intervals while the vehicle is in motion and switches to driving status automatically at a speed threshold no higher than five miles per hour, per FMCSA ELD Functions guidance.
- Motor carriers keep records of duty status and supporting documents for not less than six months from the date of receipt under 49 CFR 395.8, and a separate back-up copy of the ELD records for six months under 49 CFR 395.22.
- 49 CFR 390.6 prohibits coercing a driver into a violation, and FMCSA guidance states that a driver's written coercion complaint is filed within 90 calendar days of the event.
How many hours can a truck driver legally drive in North Carolina?
Two sets of limits apply in North Carolina, and which one governs depends on whether the transportation is interstate or intrastate commerce rather than on whether the truck crossed a state line that day. A driver in interstate commerce may drive up to 11 hours after 10 consecutive hours off duty and may not drive after the 14th consecutive hour on duty. A North Carolina intrastate carrier runs on different numbers.
| Limit | Interstate carrier, 49 CFR 395.3 | North Carolina intrastate carrier, 14B NCAC 07C .0101 |
|---|---|---|
| Driving limit | 11 hours, after 10 consecutive hours off duty | 12 hours, after 8 consecutive hours off duty |
| On-duty window | No driving after the 14th consecutive hour on duty | No driving after 16 hours on duty |
| Break | 30-minute interruption of driving status required after 8 hours of driving time | 49 CFR Parts 390 through 397 apply, subject to the exceptions the state rule lists |
| Weekly cap | 60 hours in 7 consecutive days where the carrier does not operate every day of the week, or 70 hours in 8 consecutive days where it does | 70 hours in 7 consecutive days, or 80 hours in 8 consecutive days |
| Who it covers | Commercial motor vehicles in interstate commerce | Intrastate vehicles rated 26,001 pounds or more, designed for 16 or more passengers, or placarded for hazardous materials, adopted under N.C. Gen. Stat. 20-381 |
Exception: The short-haul exception in [49 CFR 395.1(e)(1)]({U['395_1']}) applies only where every one of its conditions is met, including operating within a 150 air-mile radius of the normal work reporting location and being released from work within 14 consecutive hours. Where it applies the carrier keeps time records rather than a record of duty status.
According to 49 CFR 395.3 and FMCSA guidance on interstate and intrastate commerce, Federal Motor Carrier Safety Administration, and 14B NCAC 07C .0101, North Carolina Office of Administrative Hearings, as of August 2026.
The first question in a fatigue case is which set of hours the driver was running under. Interstate and intrastate carriers do not answer to the same numbers. A defense that the driver was still inside the limit usually depends on which limit gets applied to him. I look at where the load started and where it was going before I look at the log. A truck that never left North Carolina is a different case from a truck that came down from Virginia that morning.
Our truck crash practice page covers the rest of what a commercial vehicle case involves.
What does an electronic logging device actually record?
An electronic logging device records date, time, location, engine hours, vehicle miles and identification information for the driver, the vehicle and the motor carrier. Driving time is captured automatically once the vehicle moves, while off duty, sleeper berth and on-duty not driving remain statuses the driver selects and then certifies. Location is captured at 60-minute intervals while the vehicle is in motion and at every duty status change.
- Driving status switches on automatically once the vehicle reaches the configured speed threshold, and that threshold may not be set higher than five miles per hour, per FMCSA ELD Functions guidance.
- Location is recorded at 60-minute intervals in motion, at engine power up and shut down, at each duty status change, and when personal use or a yard move is selected, per FMCSA ELD Functions guidance.
- Location accuracy runs to about a one-mile radius during on-duty driving periods and drops to about a ten-mile radius during authorized personal use, per the FMCSA ELD checklist.
- A motor carrier must not alter or erase the original hours of service information, the source data streams behind it, or the information in any ELD that uses that data. 49 CFR 395.30.
- The driver reviews the record, corrects it, and certifies it by selecting Agree. 49 CFR 395.30. An edit never overwrites the original, every edit carries an annotation, and automatically recorded driving time may not be shortened, per FMCSA ELD editing guidance.
Exception: A driver is not required to use an ELD when the vehicle was manufactured before model year 2000, in a driveaway-towaway operation, or where a record of duty status is completed on not more than 8 days in any 30-day period. Those cases run on the paper log instead.
According to FMCSA ELD Functions FAQs, Federal Motor Carrier Safety Administration, as of August 2026.
The device is not on the driver's side and it is not on the trucking company's side. It records what the engine did. The off duty line is a different thing, because somebody typed that one. Based on my experience the automatic part of the record is often the strongest evidence in the file. It was captured before anyone knew there was going to be a case. A log written after a crash is an account of the day. Driving time captured by the engine is a record of it.
Can fuel receipts, toll records and GPS contradict a driver's log?
Yes. A motor carrier is required to keep supporting documents in five categories for every 24-hour period a driver is on duty, and no motor carrier or driver may obscure, deface, destroy, mutilate or alter the information in one of them. Toll records, GPS data and other records outside those five categories can still be evidence, but they are not governed by that same retention rule.
- Bills of lading, itineraries, schedules or equivalent documents show the origin and destination of each trip, which is testable against the times a log claims. 49 CFR 395.11.
- Dispatch records and trip records show when the load was assigned and what the carrier expected, per FMCSA supporting document guidance.
- Expense receipts tied to on-duty not-driving time carry their own timestamps and locations, and a supporting document is required to carry the driver name or identification number, the date, the location and the time, per FMCSA supporting document guidance.
- Electronic mobile communication records transmitted through a fleet management system show what the carrier told the driver and when it said it. 49 CFR 395.11.
- Payroll records and settlement sheets show what the driver was paid and how that pay was calculated. 49 CFR 395.11.
Exception: A carrier holding more than eight supporting documents for one driver's 24-hour period keeps the documents carrying the earliest and the latest time indications plus six others, so a gap in the file is not by itself proof that something was withheld. Where the driver kept paper records the carrier also retains toll receipts, and those do not count against the eight.
According to 49 CFR 395.11, Federal Motor Carrier Safety Administration, as of August 2026.
Fuel gets bought somewhere at some time. Tolls get paid somewhere at some time. A log that agrees with itself perfectly and agrees with nothing else is a red flag. Those receipts came out of systems the trucking company does not control. Each one still has to be tied to this driver and this trip before it does any work. In our experience the pay records matter as much as the receipts do, because a driver paid by the mile sits under a different kind of pressure than a driver paid by the hour. When the receipts and the log disagree the log is the document that has to explain itself.
What happens when a trucking company pressures a driver to keep moving?
Federal rules prohibit a motor carrier, shipper, receiver or transportation intermediary from coercing a driver into operating in violation of the safety regulations. A separate rule prohibits a motor carrier from requiring or permitting a driver to operate while the driver's alertness is impaired through fatigue.
- Coercion is defined as a threat to withhold business, employment or work opportunities from a driver, a threat of adverse employment action, or actually taking either action, done to induce a violation or to punish a refusal, per FMCSA coercion guidance.
- A driver who believes he was coerced files a written complaint with FMCSA no later than 90 calendar days after the event, per FMCSA coercion guidance.
- A motor carrier may not coerce a driver into falsely certifying the driver's data entries or record of duty status. 49 CFR 395.30.
- Dispatch messages sit inside the supporting document rule as electronic mobile communication records, which puts the pressure and the log in the same file. 49 CFR 395.11.
- No driver shall operate a commercial motor vehicle, and no motor carrier shall require or permit one to be operated, while the driver's alertness is so impaired through fatigue as to make it unsafe to begin or continue driving. 49 CFR 392.3.
Exception: FMCSA guidance describes coercion as a three-part sequence of a request, an objection by the driver that the task cannot be done without violating a regulation, and then a threat or a negative action. The same guidance states that coercion occurs the moment the threat is made, whether or not the driver commits the violation. [FMCSA coercion guidance]({U['coercion']}).
According to 49 CFR 390.6, Federal Motor Carrier Safety Administration, as of August 2026.
People assume a trucking case is about the driver. The driver was behind the wheel and the driver is the one who gets named when in fact the delivery window he was running against was often set somewhere else by somebody who never got in the truck. Most people don't know that a message sent through the carrier's own fleet management system is one of the five kinds of supporting document the rules already require it to keep. A text on a personal phone is a harder problem. We ask for both.
How long do these records last before they are gone?
Motor carriers are required to retain records of duty status and supporting documents for not less than six months from the date of receipt. Most North Carolina personal injury actions carry a three-year filing deadline, so the hours of service records can expire long before a lawsuit is filed.
- Records of duty status and supporting documents are retained for not less than six months from the date of receipt. 49 CFR 395.8.
- A back-up copy of the ELD records is retained for six months on a device separate from the one holding the original data. 49 CFR 395.22.
- The driver keeps a copy of the record of duty status for the previous 7 consecutive days in his possession and available for inspection while on duty. 49 CFR 395.8.
- North Carolina allows three years for most personal injury actions under N.C. Gen. Stat. 1-52(5), which is six times the federal retention floor.
- In our experience a written preservation demand sent in the first weeks is what keeps a six-month record from expiring on schedule.
Exception: Six months is a retention floor rather than a ceiling. A carrier that holds hours of service data longer under its own policy still has it, and whether a particular carrier does is a question for discovery.
According to 49 CFR 395.8, Federal Motor Carrier Safety Administration, as of August 2026.
Time is the part of a trucking case that people underestimate. The medical treatment takes months and the claim feels like something that can wait. By then the log that would have proved the hours has aged out of the file. Everything we do later to maximize the recovery starts with a record that still exists. We send the preservation demand before we send anything else.

What to do when you think a tired driver caused your crash
Fatigue cases turn on documents that have an expiration date on them. The useful thing to do early is to write down the company name off the door of the truck and the trailer number and anything else you saw, and then let an attorney send the demand that puts the carrier on notice to hold the records.
