How Hours of Service Violations Can Shape a Truck Accident Claim
After a tractor-trailer crash on a long-haul route, an early question is whether the driver was within the federal hours-of-service limits. Fatigue leaves little physical trace at a crash scene, which is why the answer tends to come from records instead of the road itself. A tractor-trailer crash lawyer looking at one of these claims will usually compare the driver's logs with every other record of the trip.
How the federal hours-of-service rules work
The Federal Motor Carrier Safety Administration (FMCSA) writes the hours-of-service rules in 49 CFR Part 395, a section of the Federal Motor Carrier Safety Regulations found in 49 CFR Parts 390-399. The core limits for property-carrying drivers are simple to state on paper. A driver can drive a maximum of 11 hours after 10 consecutive hours off duty. Driving is not allowed beyond the 14th consecutive hour after coming on duty, and off-duty time does not extend that 14-hour window. A 30-minute break is required after 8 cumulative hours of driving without at least a 30-minute interruption. Over the week, a driver may not drive after 60 hours on duty in 7 consecutive days or 70 hours in 8 consecutive days, although a 34-hour restart starts the count over.
The regulations also include exceptions. The sleeper berth provision lets a driver split the 10-hour off-duty period, provided that one period is at least 7 consecutive hours in the sleeper berth and the other is at least 2 hours. Adverse driving conditions can extend the 11-hour and 14-hour limits by up to 2 hours, and the short-haul exception applies to drivers who stay within a 150 air-mile radius and finish within https://shanedmqh914.opalvector.com/posts/what-to-expect-from-the-insurance-adjuster-after-a-truck-accident 14 hours. Whether any exception fits is a factual question, and the trucking company usually holds the records that answer it.
How investigators spot hours-of-service violations
Most drivers who must keep records of duty status now use an electronic logging device (ELD) rather than paper logs. According to the FMCSA, an ELD synchronizes with the vehicle engine to automatically record driving time, and Congress mandated the ELD rule as part of MAP-21. Electronic logs are harder to falsify than paper logs, but a log alone is rarely the whole story. Experienced truck crash attorneys know that edits, unassigned driving time and malfunction reports deserve a close look.
A careful review compares the ELD data with the supporting documents that 49 CFR 395.11 requires trucking companies to keep, such as bills of lading, dispatch records, expense receipts, fleet management messages and payroll records. Telematics and GPS data, toll transponder records, weigh station records and data from the engine control module (ECM) can show where the truck actually was and when it moved. If those sources disagree with the logs, the mismatch itself becomes evidence.
Responsibility beyond the driver
Part 395 places duties on more than the driver. The rules bar a trucking company from requiring or permitting a driver to exceed the limits, and 49 CFR 392.3 bars operating a truck while the driver's alertness is impaired by fatigue, regardless of what the log says. Dispatch schedules that cannot be met legally and pay plans that reward speed can point to claims against the company itself, including negligent supervision, in addition to vicarious liability for the driver's conduct.
Research cited by the Insurance Institute for Highway Safety (IIHS) found that a truck driver's hours-of-service or logbook violations made it more likely that the driver would be found to have precipitated the crash. A study cannot decide an individual case, but it does explain why a truck crash attorney treats the logs as a priority.
Keeping the records from disappearing
Under 49 CFR 395.8, the minimum retention period for records of duty status and supporting documents is six months. This is one reason a truck accident attorney often sends a preservation letter early, asking the trucking company to keep the ELD data, ECM downloads, dispatch messages and the driver qualification file. The letter does not prove what existed, but it puts the company on notice, and destroying evidence after notice can lead to spoliation sanctions in many courts.
Deadlines and shared fault
Every state sets its own statute of limitations for injury and wrongful death claims, and the periods vary by state. Most states also apply comparative negligence, which can reduce what an injured person recovers by that person's share of fault.
