A truck driver’s logbook might not seem like a powerful piece of evidence, but in an Arkansas truck accident injury case, it can be one of the most important documents in your claim.
Federal hours-of-service rules set strict limits on how long a commercial truck driver can stay behind the wheel before resting.
When a driver violates those limits and causes a crash, the violation itself may serve as evidence a jury can consider when determining negligence in your injury case.
If you were hurt in a truck accident on an Arkansas highway, understanding how these federal rules work and how they connect to your legal claim can make a real difference in the outcome of your case.
These rules exist because fatigued driving is a significant safety risk on the road, and the stakes are even higher when the fatigued driver is operating an 80,000-pound commercial vehicle.
How Do FMCSA Hours-of-Service Rules Protect Drivers on Arkansas Roads?
The Federal Motor Carrier Safety Administration (FMCSA) enforces hours-of-service (HOS) regulations under 49 CFR Part 395 to prevent truck driver fatigue and reduce the risk of serious crashes.
These rules generally apply to motor carriers and CMV drivers covered by Part 395, including the thousands of trucks that travel through Arkansas on I-40, I-30, and I-49 every day, though certain short-haul, agricultural, and other limited categories of drivers may qualify for specific exceptions.
The rules set four core limits that control how long a property-carrying truck driver can drive and work before taking mandatory rest.
The 11-hour driving limit is the foundation of the entire HOS framework, and it means a driver cannot drive for more than 11 hours after taking 10 consecutive hours off duty.
The 14-hour on-duty window is the rule that many drivers misunderstand, because it generally runs continuously from the moment a driver begins any work-related activity and does not pause for meals, fuel stops, or time spent waiting at a loading dock, although qualifying split sleeper-berth periods may affect the calculation.
Even if a driver has only used six of their 11 driving hours, they cannot drive once the 14-hour window closes.
The 30-minute break requirement means a driver must take at least a 30-minute break before driving if eight cumulative hours of driving time have passed without a qualifying interruption, and that break may consist of off-duty time, sleeper berth time, or on-duty non-driving time.
The 60/70-hour weekly limit prohibits a driver from driving a CMV after accumulating 60 or 70 on-duty hours over a seven-day or eight-day period, depending on the carrier’s operating schedule.
Carriers that operate vehicles every day of the week must follow the 70-hour-in-eight-days rule, while those operating fewer days follow the 60-hour-in-seven-days rule.
These are not suggestions or guidelines. They are federal laws, and a violation can be used as evidence in a civil injury claim.
Why Is Driver Fatigue So Dangerous in Truck Accidents on Arkansas Highways?
Driver fatigue impairs a truck driver’s ability to react, judge distances, and stay in their lane in ways that are measurably similar to alcohol impairment.
According to the U.S. Occupational Safety and Health Administration (OSHA), being awake for 17 consecutive hours produces cognitive impairment comparable to a blood alcohol content (BAC) of 0.05%, and being awake for 24 hours raises that impairment to the equivalent of a 0.10 percent BAC, which exceeds the legal limit for any driver.
A truck driver who has been awake for extended periods after pushing past their HOS limits may be operating with a level of impairment comparable to alcohol intoxication, but behind the wheel of a vehicle that can weigh up to 80,000 pounds.
NHTSA reported that 5,340 people were killed in crashes involving large trucks in 2024, and 3,753 of those fatalities were occupants of other vehicles.
Roughly 70% of the people killed in those crashes were in passenger cars, SUVs, or other non-truck vehicles.
This means the people most likely to be seriously hurt or killed when a fatigued truck driver causes a crash are everyday drivers, passengers, and pedestrians.
Arkansas carries substantial interstate freight traffic because of its position along major commercial corridors.
Interstates 40 and 30 carry heavy volumes of commercial truck traffic through the state, connecting freight routes between Texas, Tennessee, and the broader Southeast.
Consider a scenario where a long-haul driver hauling poultry processing equipment from Fort Smith to Memphis along I-40 has been on duty for 15 hours after a delayed loading at the shipper’s dock.
The driver still has unused driving time under the 11-hour rule but has blown past the 14-hour window.
Fatigued and fighting to stay alert in the early morning hours near Russellville, the driver drifts across the center line and strikes a passenger vehicle head-on.
In that simplified hypothetical, assuming the driver was subject to the ELD requirement and no exception applied, the ELD data would likely show a clear 14-hour violation, and that violation could be powerful evidence of negligence in the injured person’s claim.
How Can an HOS Violation Help Prove Negligence in Your Arkansas Truck Accident Claim?
An hours-of-service violation can serve as strong evidence of negligence because it shows the truck driver was operating outside the legal limits designed to keep the roads safe.
In Arkansas, a plaintiff in a personal injury case must generally show that the defendant owed a duty of care, breached that duty, and caused harm as a result of the breach.
When a truck driver violates a federal safety regulation like the HOS rules, that violation may be treated as evidence that the driver failed to meet the standard of care required by law.
A jury can consider the violation as a factor in determining whether the driver was negligent, even though the violation alone does not automatically prove the driver caused the crash.
You still need to connect the violation to the accident, which means showing that the driver’s fatigue or impaired condition contributed to the collision.
This is where the strength of the evidence matters.
If ELD records show the driver had been on duty for 16 hours at the time of the crash, and the crash involved lane departure or failure to brake, a reasonable connection between fatigue and the collision becomes much easier to establish.
The trucking company may also face liability for the violation.
Under federal regulations, motor carriers are responsible for ensuring their drivers comply with HOS rules, and a carrier that pressures drivers to keep driving past their limits, or that fails to monitor compliance, can be held liable for negligent supervision or negligent entrustment.
What Evidence Proves a Truck Driver Exceeded Hours-of-Service Limits?
Electronic logging devices (ELDs) are the primary tool used to track and prove HOS compliance, and they are required on nearly all commercial motor vehicles operating in interstate commerce.
ELDs connect directly to the truck’s engine and automatically record driving time based on vehicle movement, while drivers manually select their non-driving duty statuses such as off-duty, sleeper berth, and on-duty not driving.
Unlike the paper logbooks that drivers used in the past, ELDs are more difficult to falsify without leaving an electronic record because automatically recorded driving time generally cannot be changed to non-driving time, and the system preserves original records along with any edit history.
This makes ELD records one of the most reliable pieces of evidence in a truck accident injury claim.
However, ELD data is not permanent. Under FMCSA regulations, motor carriers are only required to retain ELD records for six months from the date they were created.
That six-month window creates an urgent deadline in any truck accident case because if the records are not preserved through a formal preservation letter or litigation hold, they may be disposed of after the retention period expires, before your attorney can obtain them.
Beyond ELD data, other supporting documents can help prove HOS violations.
These include fuel receipts and toll records that show when and where the truck was traveling, GPS and telematics data from the truck’s onboard systems, bills of lading and delivery receipts that show pickup and drop-off times, dispatch records and communication logs between the driver and the carrier, and the driver’s records of duty status (RODS) from the crash date and the preceding days or weeks, depending on the issues being investigated.
Each of these documents can help reconstruct the driver’s schedule in the days leading up to the accident and reveal whether the driver was consistently pushing against or exceeding HOS limits.
How Do Insurance Companies Use Hours-of-Service Issues Against Arkansas Truck Accident Victims?
Insurance companies representing trucking companies and their drivers use sophisticated tactics to try to reduce your truck accident claim, and HOS-related evidence is no exception. Understanding these tactics is essential if you want to protect the full value of your claim.
One common tactic is rushing to settle before ELD data can be fully analyzed.
An insurer may make an early settlement offer before all electronic evidence has been reviewed, and ELD records and supporting documents can reveal damaging patterns of HOS violations that a quick, low settlement would not account for.
Accepting a fast offer before the full scope of the driver’s violations is uncovered can leave significant compensation on the table.
Another tactic involves disputing the connection between fatigue and the crash. Even when ELD data clearly shows an HOS violation, the defense may dispute whether the violation actually contributed to the accident.
The defense may argue that the driver was well-rested despite exceeding the 14-hour window, or that road conditions, weather, or the actions of another driver caused the crash rather than fatigue.
This argument is intended to break the causal link between the violation and your injuries.
A third tactic is using your own driving behavior to inflate your share of fault under Arkansas’s modified comparative fault rule, codified in Arkansas Code Section 16-64-122. Under this rule, if you are found to be 50% or more at fault for the crash, you recover nothing.
The defense may point to minor driving infractions, your speed at the time of the crash, or the timing of your lane change to argue that your conduct contributed to the collision.
This approach could reduce your compensation proportionally or, if fault reaches the 50 percent threshold, bar your recovery entirely under Arkansas law.
What Challenges Make HOS-Based Truck Accident Claims Difficult in Arkansas?
Proving that an HOS violation caused or contributed to a truck accident involves several challenges that can catch injured people off guard if they are not prepared.
The first and most time-sensitive challenge is preserving the evidence. As noted above, FMCSA rules only require carriers to keep ELD records for six months.
Arkansas’s statute of limitations for personal injury claims is three years from the date of the accident, which means there is a significant gap between the time the evidence may be destroyed and the deadline to file a lawsuit.
If you wait too long to contact an attorney, critical ELD data, dispatch logs, and GPS records may be gone by the time your case gets started.
A second challenge involves distinguishing between different types of electronic data on the truck.
Many people confuse ELDs with event data recorders (EDRs), sometimes called “black boxes,” but these are separate systems that serve different purposes.
An ELD tracks the driver’s hours and duty status, while an EDR may record crash-related data such as speed, braking, and throttle position in the seconds before and during a collision, though the specific data available varies by truck manufacturer and installed systems.
Both types of data can be valuable in a truck accident claim, but they answer different questions and require different methods of collection and analysis.
A third challenge is dealing with carriers that attempt to obscure or manipulate HOS records.
During the 2025 CVSA International Roadcheck, hours-of-service violations accounted for 32.4% of all driver out-of-service violations, making HOS the single most common reason drivers were pulled off the road during the 72-hour enforcement event.
Inspectors also found that 10% of driver out-of-service violations involved falsified logs or records of duty status.
If ELD data appears incomplete or records have been falsified, your legal team may need to use supporting documents like fuel receipts, GPS data, and toll records to reconstruct the driver’s actual schedule.
This type of investigation requires resources and technical knowledge that most injury victims cannot access on their own.
How Does Arkansas’s Comparative Fault Rule Interact with HOS Violation Claims?
Arkansas’s modified comparative fault system, governed by Arkansas Code Section 16-64-122, creates a 50 percent bar that can eliminate your claim entirely if the defendant’s legal team successfully shifts enough fault onto you.
This rule has a direct impact on truck accident cases involving HOS violations because the trucking company’s defense strategy will often focus on finding any reason to assign fault to the injured person.
For example, if you were traveling five miles per hour over the speed limit at the time of the crash, the defense may argue that your speeding contributed to the severity of the collision even though the truck driver was operating in violation of federal HOS rules.
If a jury assigns you 50% or more of the fault, you lose your right to any compensation, regardless of how severe your injuries are. This is why documenting the truck driver’s HOS violation is so important.
Strong evidence of a federal safety violation shifts the focus of the case back to the truck driver and the carrier, making it harder for the defense to credibly argue that you were primarily responsible.
An HOS violation also opens the door to potential claims against the motor carrier for failing to monitor driver compliance, pressuring drivers to exceed their limits, or maintaining a corporate culture that prioritizes delivery schedules over safety.
What the 2026 HOS Regulatory Landscape Means for Your Claim
The FMCSA has introduced two programs under the Pro-Trucker Package and, as of early 2026, was conducting limited pre-testing before broader pilot participation.
The Flexible Sleeper Berth (FSB) pilot program would expand sleeper berth split options to include 6/4 and 5/5 splits, while the Split Duty Period (SDP) pilot program would allow drivers to pause their 14-hour window for up to three hours of non-driving time.
These pilot programs are still in the testing phase and are limited to a small number of participants. They do not change the current HOS rules for the vast majority of commercial drivers.
However, if you are involved in a truck accident and the driver was participating in one of these pilot programs, the legal analysis of whether an HOS violation occurred may be more complicated.
This is another reason why working with attorneys who understand federal trucking regulations is important in Arkansas truck accident cases.

Frequently Asked Questions About Hours-of-Service Rules and Arkansas Truck Accident Claims
What are the FMCSA hours-of-service rules for truck drivers?
The FMCSA hours-of-service rules under 49 CFR Part 395 set federal limits on how long commercial truck drivers can drive and work before they must rest. Property-carrying drivers may drive a maximum of 11 hours after 10 consecutive hours off duty, cannot drive beyond the 14th consecutive hour after coming on duty, must take a 30-minute break once eight cumulative hours of driving have passed without a qualifying interruption, and cannot drive after accumulating 60 on-duty hours in seven days or 70 on-duty hours in eight days. These rules are designed to reduce fatigue-related crashes and apply to nearly all commercial motor vehicle drivers operating in interstate commerce.
How can hours-of-service violations help my Arkansas truck accident injury claim?
An HOS violation can serve as evidence that the truck driver was operating outside of federally mandated safety limits, which may help prove negligence in your injury case. If ELD records show the driver exceeded the 11-hour driving limit or the 14-hour on-duty window at the time of your crash, that data can be used to demonstrate that the driver’s fatigue contributed to the collision. The violation may also support claims against the trucking company for failing to monitor or enforce compliance with federal regulations.
How long does the trucking company have to keep ELD records after a crash?
Under FMCSA regulations, motor carriers are required to retain ELD records for six months from the date they were created. Arkansas’s statute of limitations for personal injury claims is three years, which creates a significant gap between when records may be legally destroyed and the deadline to file a lawsuit. This is why it is critical to contact an attorney as soon as possible after a truck accident so a formal preservation letter can be sent before any records are lost.
Can I still recover compensation if I was partially at fault for the truck accident?
Under Arkansas Code Section 16-64-122, you can recover compensation as long as your share of fault is less than 50 percent. If you are found to be 50 percent or more at fault, you cannot recover any damages. Your compensation is reduced by your percentage of fault. For example, if a jury finds you 20 percent at fault and the total damages are $500,000, you would receive $400,000. Insurance companies often try to inflate your share of fault to reduce or eliminate your payout, which is why strong evidence of the truck driver’s HOS violation is so valuable in protecting your claim.
What is the difference between an ELD and a truck’s black box?
An electronic logging device (ELD) tracks the driver’s hours of service, recording driving time, on-duty time, off-duty time, and sleeper berth time. It connects to the truck’s engine and runs automatically. A truck’s event data recorder (EDR), sometimes called the “black box,” may record crash-related data such as speed, braking, and throttle position in the seconds before and during a collision, though the specific data captured varies by manufacturer and installed systems. Both types of data can be important evidence in a truck accident claim, but they serve different purposes and may need to be collected separately.
Why is it important to act quickly after a truck accident involving a fatigued driver?
Acting quickly is important because critical evidence in truck accident cases can disappear within weeks or months. ELD data must only be retained for six months under federal rules, and trucking companies may also overwrite GPS data, dispose of dispatch logs, or repair and return the truck to service before crash-related data can be preserved. A prompt preservation letter can identify relevant evidence and support later arguments that the carrier knew the material should be preserved. Delays in getting legal representation can result in the loss of evidence that might have proven the driver’s HOS violations and strengthened your claim.
