FMCSA hours of service violations in NC truck crash claims

A tractor-trailer drifts across the center line on US-17 before sunrise, or rear-ends a line of stopped cars on I-40 without braking. When the driver later says they never saw the traffic, one of the first questions is how long they had been behind the wheel. Federal law sets hard limits on that, and the records that show whether the driver stayed within them are often the most useful evidence in a truck case.

I’m Robert L Armstrong, and I have represented injury victims and their families in the Wilmington area for over 41 years. This guide explains the federal hours of service limits, the exceptions trucking companies rely on, the different rules for trucks that stay inside North Carolina, and how a logbook violation becomes evidence in an injury claim.

The daily and weekly limits in the federal rules

Most of the 18-wheeler crashes I handle involve interstate carriers, and those drivers follow the property-carrying limits in 49 CFR 395.3. The rule binds both sides. The driver may not drive past the limits, and the motor carrier may not “permit or require” a driver to do so.

The 10-hour reset and the 14-hour window

A driver may not start a driving shift without first taking 10 consecutive hours off duty. Once the driver comes on duty, a 14-hour clock starts. After the 14th consecutive hour, the driver may not drive again until taking another 10 hours off. Lunch, fueling, and waiting at a loading dock all count against the 14 hours. Off-duty breaks don’t stop the clock.

The 11-hour driving limit and the 30-minute break

Inside that 14-hour window, the driver may drive a total of 11 hours. A driver who has driven 8 cumulative hours without at least a 30-minute interruption must stop for 30 minutes before driving again. The break can be off duty, in the sleeper berth, or on duty but not driving, such as fueling.

The 60 and 70-hour limits and the 34-hour restart

The weekly limits look at on-duty time, not only driving. A driver for a carrier that doesn’t run trucks every day may not drive after 60 hours on duty in 7 consecutive days. A driver for a carrier that runs every day may not drive after 70 hours on duty in 8 consecutive days. The driver can reset that 7 or 8 day period by taking 34 or more consecutive hours off duty.

Exceptions that can stretch a driver’s day

Most of the disputes I see in hours of service cases are about exceptions. A carrier rarely says its driver ignored the rules. It says an exception applied. The main ones are in 49 CFR 395.1.

Sleeper berth split. A driver with a sleeper berth can split the 10-hour reset into two periods, as long as one is at least 7 consecutive hours in the berth, the other is at least 2 hours, and the two add up to at least 10. In practice that means a 7 and 3 split or an 8 and 2 split. When the split is done correctly, neither rest period counts against the 14-hour window. When it’s done wrong, the driver may have been over the limit for hours without the log showing it plainly.

Adverse driving conditions. A driver who runs into snow, ice, sleet, fog, or unusual road or traffic conditions may drive up to 2 extra hours beyond the 11-hour limit and the 14-hour window to finish the run or reach a safe place. The conditions must be ones the driver or carrier couldn’t reasonably have known about before the shift or dispatch. Weather that was in the forecast when the truck left the yard usually doesn’t qualify.

Short-haul exception. A driver who stays within a 150 air-mile radius of the normal work reporting location and is released from work within 14 consecutive hours does not have to keep a log or use an electronic logging device. The carrier must instead keep time records for 6 months showing when the driver reported, how long they worked, and when they were released. These drivers are also exempt from the 30-minute break. Many local delivery trucks and trucks running between the Port of Wilmington and nearby warehouses operate under this exception, so the paperwork looks very different from a long-haul case.

FMCSA has announced upcoming pilot programs on flexible sleeper berth splits and split duty periods. Those pilots don’t change the rules described here, which are the ones in force as of October 2026.

Who has to use an ELD and who is exempt

An ELD is an electronic logging device, a unit wired to the truck’s engine that records driving time automatically. Under 49 CFR 395.8 and Subpart B of Part 395, carriers subject to the hours of service rules have had to use ELDs since December 18, 2017. Before that, many drivers kept paper logbooks, which were much easier to fill in after the fact.

The regulation lets a carrier use paper records of duty status instead of an ELD in a few situations:

• The driver has to keep a record of duty status on no more than 8 days in any 30-day period.
• The truck is being delivered as part of a driveaway-towaway operation, or the vehicle being towed is a motor home or recreational vehicle trailer.
• The truck was manufactured before model year 2000, based on the VIN on the registration.

Short-haul drivers who qualify for the 150 air-mile exception don’t need an ELD or a log at all, only the carrier’s time records. Knowing which category a driver fell into tells me what records should exist and where gaps might be hiding.

How North Carolina applies the hours of service rules to intrastate trucks

The federal rules cover carriers in interstate commerce. North Carolina extends them to many trucks that never cross the state line. Under 14B NCAC 07C .0101, the federal safety rules in 49 CFR Parts 390 through 397 apply to intrastate carriers whose vehicles weigh or are rated at 26,001 pounds or more, are designed to carry 16 or more passengers, or haul placarded hazardous materials.

The same rule sets different hours for intrastate drivers. An intrastate driver may not drive more than 12 hours after 8 consecutive hours off duty, may not drive after being on duty 16 hours following 8 hours off, and is capped at 70 hours on duty in 7 consecutive days or 80 hours in 8 days. A dump truck running between a quarry and a job site in Pender County may be measured against those numbers rather than the federal ones. Getting the right rulebook matters, because a driver who looks over the limit under federal rules may be within the state limit, and the reverse can be true too.

How an hours of service violation shows up in an injury case

Hours of service rules exist because tired drivers crash. FMCSA’s Large Truck Crash Causation Study coded 13 percent of truck drivers in the crashes it studied as fatigued at the time of the crash. Research from the AAA Foundation for Traffic Safety, using in-vehicle cameras on ordinary drivers, found drowsiness in 9.5 percent of all crashes it observed. Fatigue is hard to see after a crash, so the logs are often how it gets proven.

Comparing the ELD against everything else

The ELD shows what the driver logged. Federal rules also require carriers to keep supporting documents, including bills of lading, dispatch and trip records, expense receipts, fleet messaging records, and payroll or settlement records. Those documents carry their own timestamps. A fuel receipt in Florence, South Carolina at 2 a.m. doesn’t fit a log showing the driver asleep in the berth at that hour. Toll records, GPS data, delivery appointments, and the truck’s engine data can tell the same story from other angles.

Falsified logs as evidence

Under 49 CFR 395.8(e), no driver or carrier may make a false report about duty status, and neither may tamper with or block an ELD so it doesn’t record accurately. When the logs and the receipts disagree, the gap is evidence on its own. False off-duty entries can also suggest the driver knew they were over the limit and kept driving anyway.

The carrier’s role

Because the hours rule says a carrier may not “permit or require” a violation, a carrier’s dispatch practices are part of the case. Delivery windows that can’t be met legally, messages pushing a driver to keep moving, and pay structures tied to miles all bear on whether the company shares the blame. A separate rule, 49 CFR 392.3, bars a driver from operating a truck while too fatigued or ill to drive safely, and bars the carrier from requiring or permitting it. That rule can apply even when the driver was technically within the hours limits. The company’s insurance limits usually decide how much coverage stands behind those claims.

Is an hours of service violation negligence in North Carolina?

Negligence means failing to use reasonable care. North Carolina courts generally treat the violation of a public safety statute as negligence per se, which means the violation itself can establish the careless conduct. Whether a particular federal trucking regulation gets that same treatment depends on the rule and the facts, and courts haven’t always agreed. I build these cases so they don’t depend on that shortcut.

Either way, a violation alone doesn’t win the case. I still have to show the violation connects to the crash, for example that the driver who was 3 hours past the 14-hour window also drifted out of the lane or reacted late. The other side of the case matters as much. North Carolina’s contributory negligence rule can bar an injured person from recovering anything if they were even slightly at fault, and trucking insurers know that rule well. Strong log evidence about the truck driver helps answer an argument that the injured driver changed lanes too close to the truck or braked too suddenly.

Why the 6-month record clock matters

Under 49 CFR 395.8(k), a carrier must keep records of duty status and supporting documents for at least 6 months from the date it receives them. Short-haul time records have the same 6-month floor. After that, the carrier can generally discard them in the ordinary course of business.

A preservation letter changes that. It tells the carrier and its insurer that a claim is coming and that they must keep the logs, ELD data, receipts, dispatch messages, and engine data. My truck crash guide covers the other early steps and the shorter clocks on drug testing and black box data. For hours of service evidence, the main point is that 6 months passes quickly when someone is in the hospital or out of work.

FMCSA hours of service FAQs

How many hours can a truck driver drive in a day? ▶

Under the federal rules, a property-carrying driver may drive up to 11 hours after 10 consecutive hours off duty, and may not drive at all after the 14th hour since coming on duty. A driver who has driven 8 hours without a 30-minute break must stop and take one before driving again. Adverse weather or unexpected road conditions can extend the driving limit and the 14-hour window by up to 2 hours.

Do the FMCSA hours of service rules apply to trucks that never leave North Carolina? ▶

Often, yes, but with different numbers. North Carolina’s rule, 14B NCAC 07C .0101, applies the federal safety regulations to intrastate trucks of 26,001 pounds or more, vehicles designed for 16 or more passengers, and placarded hazmat loads. Intrastate drivers may drive 12 hours after 8 hours off and may not drive after 16 hours on duty, with a 70-hour limit over 7 days or 80 hours over 8 days.

If the truck driver broke the hours of service rules, do I automatically win? ▶

No. A violation is strong evidence, but I still have to show it connects to the crash, for example that the driver was fatigued, drifted, or reacted late. The trucking company’s insurer also looks for any fault on the injured driver’s side, because North Carolina’s contributory negligence rule can bar recovery entirely. The log violation is one piece of a larger proof.

What if the trucking company says the driver’s logs were clean? ▶

A clean log doesn’t end the review. ELD records can be edited, drivers sometimes log driving as off duty, and short-haul drivers may not keep logs at all. I compare the logs against fuel and toll receipts, bills of lading, dispatch messages, GPS data, and payroll records, which federal rules treat as supporting documents.

What if the crash killed a family member? ▶

The family may have a wrongful death claim through the estate, and the same hours of service evidence applies. North Carolina’s filing deadline for wrongful death is two years from the date of death, but the driver’s logs may only have to be kept for 6 months, so the evidence clock runs out first.

How much does it cost to talk with you about a truck crash? ▶

The consultation is free, and there is no fee unless I win. In that first conversation I go over what happened, which trucking records should be preserved, and how case costs are handled, before you decide anything.

Talking to a Wilmington truck accident lawyer about a fatigued driver

An hours of service case comes down to a few questions. Which rules applied to this driver, federal or North Carolina intrastate? Did an exception really fit? Do the logs match the receipts, messages, and engine data? Were those records preserved before the 6-month window closed? The answers often show whether the driver was too tired to be on the road and whether the company knew it.

I handle these cases personally and work with injury victims and their families across New Hanover, Brunswick, Pender, Onslow, Bladen, and Duplin counties.
