Hours of Service (HOS) violations can provide a written record showing that a trucker stayed behind the wheel longer than federal safety rules allowed. When a driver exceeds those limits on I-10, I-35, or I-45, electronic logs can show how long they had been driving before the crash.
An HOS violation doesn’t automatically prove negligence or establish that fatigue caused the wreck. The violation can become important evidence when the timing, driving behavior, and other records connect excessive hours to the crash.
Timing also matters because carriers generally don’t have to keep every Hours of Service record indefinitely. Preserving the logs and supporting records can become an important part of a fatigue claim.
Key Takeaways for Hours of Service Violations
- Federal rules generally limit property-carrying truckers to 11 hours of driving within a 14-hour window after 10 consecutive hours off duty.
- Texas uses different Hours of Service limits for certain drivers operating only within the state.
- Electronic logging devices record driving time and other information that can help identify HOS violations.
- Fuel receipts, toll records, GPS data, and dispatch messages can expose gaps between a driver’s logs and the truck’s actual movements.
- Motor carriers aren’t allowed to require drivers to violate Hours of Service limits.
Quick Answer: What Counts as an Hours-of-Service Violation in a Truck Accident?
An Hours of Service violation happens when a trucker exceeds federal driving or on-duty limits, such as driving more than 11 hours after 10 consecutive hours off duty or driving beyond the 14-hour window.
In a truck accident claim, ELD records showing a violation can help establish whether fatigue contributed to the crash.
What Hours of Service Rules Do Truck Drivers Have To Follow?
Truck drivers hauling property in interstate commerce generally follow the Hours of Service rules from the federal Motor Carrier Safety Administration (FMCSA) in 49 C.F.R. Part 395. These rules limit daily driving, the length of the workday, and cumulative on-duty hours.
The core limits for property-carrying drivers include:
- 11-Hour Driving Limit: After 10 consecutive hours off duty, a driver can drive for up to 11 hours.
- 14-Hour Driving Window: A driver generally can’t drive after the 14th consecutive hour after coming on duty.
- 30-Minute Break: After eight cumulative hours of driving without at least a 30-minute interruption, the driver must take a qualifying 30-minute break.
- 60/70-Hour Limit: A driver can’t drive after 60 hours on duty in seven consecutive days or 70 hours in eight consecutive days, depending on the carrier’s schedule.
- 34-Hour Restart: A driver can restart the seven- or eight-day period after at least 34 consecutive hours off duty.
- Sleeper Berth Split: Qualifying sleeper-berth periods can be split under federal rules when the required conditions are met.
Federal rules also include exceptions. The adverse driving conditions provision, for example, can extend certain driving and on-duty limits when qualifying unexpected conditions delay a trip.
Texas Intrastate HOS Rules
Texas uses different HOS limits for qualifying drivers operating entirely within the state. Those rules generally allow up to 12 hours of driving following eight consecutive hours off duty and prohibit driving after 15 hours on duty.
That distinction matters in areas like DFW, where some trucks run entirely within Texas between warehouses in south Dallas, Lancaster, Fort Worth, and other distribution hubs. Determining whether state or federal limits applied is one of the first questions in a fatigue case.
How Does Trucker Fatigue Cause Accidents?
Trucker fatigue can slow reaction time, reduce attention, and cause brief lapses in awareness. A tired driver might miss stopped traffic, drift from a lane, or react too late to changing road conditions.
Fatigue also doesn’t always announce itself clearly after a wreck. Unlike alcohol impairment, there’s no roadside test that establishes how tired someone was before impact. That makes the surrounding evidence important.
Signs that fatigue could have contributed to a truck crash include:
- No Braking Before Impact: Truck data showing little or no braking before hitting stopped traffic can support an argument that the driver failed to react in time.
- Lane Drift: Video or witness accounts showing the truck repeatedly crossing lane markings can point to reduced alertness.
- Late-Night or Early-Morning Driving: The FMCSA identifies midnight to 6 a.m. as one of the periods when drivers are naturally more prone to drowsiness.
- Long Periods Without Stops: GPS data, toll records, or fuel receipts can show that a truck remained in motion for long stretches that don’t match the driver’s reported rest periods.
Work pressure can also matter. Delivery schedules, loading delays, and compensation structures sometimes create incentives for drivers to keep moving when they should stop.
How Does ELD Data Help Prove an HOS Violation?
Electronic logging device (ELD) data helps prove an Hours of Service violation by creating a timestamped record of driving time and duty status. Those records can be compared with GPS information, fuel purchases, dispatch records, and other evidence to determine whether the driver exceeded legal limits.
The electronic logging and black box evidence from a commercial truck can become especially important when the carrier’s version of the trip doesn’t match the physical records.
What an Electronic Logging Device Records
An ELD connects with the truck’s engine and records information such as driving time, engine hours, vehicle movement, and location data. The driver records other duty statuses, including on-duty not driving, off duty, and sleeper berth.
ELD systems also retain information about edits, which can help show whether entries were changed after they were first recorded.
How Hours-of-Service Violations Can Be Hidden
ELDs make falsifying driving time harder, but they don’t eliminate the possibility. Disputes can involve improper use of personal conveyance, unassigned driving time, or activity recorded under the wrong driver.
Comparing the ELD with GPS data, engine records, fuel purchases, delivery timestamps, and other records can expose inconsistencies.
What Other Records Can Prove an HOS Violation?
ELD data isn’t the only evidence that can prove an HOS violation. Supporting records can establish where the truck was and when it was moving.
Those records can include:
- Fuel Receipts: Purchase times and locations can place the truck at specific points along its route.
- Toll Records: Electronic toll data can establish when a truck passed through particular locations.
- Bills of Lading: Pickup and delivery times can help reconstruct the driver’s workday.
- Dispatch Records: Messages between the carrier and driver can show delivery demands, delays, and schedule changes.
- GPS Data: Fleet tracking information can show the truck’s location and movement even when the log contains gaps.
Who Can Be Liable When a Fatigued Trucker Causes a Crash?
The driver and motor carrier can face liability when fatigue contributes to a truck crash. Other companies can also come under scrutiny if their own conduct pressured or encouraged the driver to violate safety rules.
The same federal trucking regulations that limit a driver’s hours also place duties on motor carriers and prohibit certain forms of coercion.
The Truck Driver
A driver can be negligent for continuing to drive after exceeding legal limits or when fatigue makes it unsafe to stay behind the wheel. An HOS violation strengthens that evidence when the excessive driving time connects to the conduct that caused the crash.
The Motor Carrier
Federal rules prohibit a motor carrier from permitting or requiring a driver to violate applicable Hours of Service limits. A carrier’s own conduct can become important when evidence shows that it ignored repeated violations, created unrealistic delivery schedules, or pressured drivers to stay on the road despite fatigue.
Shippers, Receivers, and Brokers
FMCSA rules also prohibit motor carriers, shippers, receivers, and transportation intermediaries from coercing drivers to violate certain safety regulations. Emails, texts, dispatch messages, contracts, and delivery records can help show whether another company pressured the driver to continue operating despite an Hours of Service problem.
How Does a Truck Accident Lawyer Use Hours of Service Evidence?
A Texas truck accident lawyer can use Hours of Service records to reconstruct the driver’s schedule and determine whether excessive driving or fatigue contributed to the crash. The investigation often involves comparing carrier records against independent evidence that shows where the truck actually was and when it was moving.
Much of this evidence sits with the trucking company or other businesses rather than the injured person.
A lawyer’s work commonly includes:
- Preserving the Records: A preservation demand can identify ELD data, dispatch messages, GPS records, supporting documents, and other evidence that should be retained.
- Comparing the Timeline: Fuel purchases, toll records, delivery times, and GPS data can reveal discrepancies in the driver’s reported hours.
- Reviewing Carrier Practices: Safety and compliance records can show whether the carrier had a broader problem with Hours of Service violations.
- Connecting Fatigue to the Crash: Truck data, witness accounts, video, and medical or accident-reconstruction evidence can help establish whether fatigue actually contributed to what happened.
FAQ for Hours of Service Violations
Can I Prove an Hours of Service Violation Without the ELD?
You can prove an Hours of Service violation with evidence other than the ELD. Fuel receipts, toll records, GPS data, delivery timestamps, dispatch messages, and other records can help reconstruct how long the driver was working.
Those records become especially important when the electronic log is incomplete or disputed.
Do Federal HOS Rules Apply to Local Delivery Drivers?
The FMCSA’s Hours of Service rules can apply to local delivery drivers, although some qualify for the short-haul exception. Qualifying drivers generally must stay within a 150-air-mile radius and return to their reporting location within the required time limits.
The exception can change the recordkeeping requirements, but it doesn’t give a driver unlimited hours behind the wheel.
What if the Trucker Was Within Legal Hours but Still Exhausted?
A trucker can still act negligently by driving while too fatigued to operate safely, even without exceeding the numerical HOS limits. Federal law separately prohibits operating a commercial vehicle when illness or fatigue impairs the driver’s ability or alertness.
The HOS limits set maximum driving periods. They don’t guarantee that every driver who remains within those limits is safe to continue driving.
Does a Logbook Violation Automatically Prove My Texas Truck Accident Claim?
A logbook violation doesn’t automatically establish liability for a truck crash. The evidence still has to connect the violation or fatigue to what happened. A paperwork mistake unrelated to the collision can carry little weight. A substantial HOS violation combined with evidence that the driver failed to brake, drifted from a lane, or fell asleep presents a much stronger connection.
Does Sleep Apnea Matter in a Trucker Fatigue Claim?
Sleep apnea can matter in a truck accident claim when evidence shows the condition contributed to the driver’s fatigue. The condition can disrupt sleep and leave someone drowsy despite spending enough time off duty.
A fatigue claim involving sleep apnea usually turns on the driver’s medical qualification, treatment history, symptoms, and what the carrier knew rather than the diagnosis alone.
Why Hours of Service Records Matter After a Fatigue Crash
Hours of Service records can show whether a truck driver stayed on the road beyond legal limits, but the violation is only part of the case. The stronger question is whether the excessive hours contributed to the driving mistake that caused the collision.
A Texas truck accident lawyer can subpoena the driver’s logs when litigation requires records that the carrier won’t provide voluntarily. DFW Injury Lawyers can preserve and compare ELD data, dispatch records, GPS information, and other trucking evidence when fatigue is disputed.
