Hours of Service Violations in Semi-Truck Crash Claims
When a semi-truck crash happens near the end of a long shift, one of the first questions is https://truckaccidentlawyers.wiki/guides/comparing-truck-accident-attorneys/ whether the driver had stayed inside the federal hours-of-service limits. Fatigue leaves little physical trace at a crash scene, so the answer usually comes from records rather than the roadway. A truck accident lawyer reviewing one of these cases usually starts by comparing the driver's logs against every other record of the trip.
How the federal hours-of-service rules work
The Federal Motor Carrier Safety Administration (FMCSA) sets 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. For property-carrying drivers, the core limits are simple to state. A driver can drive a maximum of 11 hours after 10 consecutive hours off duty. The driver may not drive 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, and 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, as long as 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 covers drivers who remain inside a 150 air-mile radius and are released within 14 hours. Whether any exception fits is a factual question, and the trucking company usually holds the records that answer it.
How hours-of-service violations come to light
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 through 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. GPS and telematics 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.
When the company shares responsibility
The duties in Part 395 reach beyond the driver. A trucking company may not require or permit 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 support claims against the company itself, such as 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 increased the likelihood that the driver would be found to have precipitated the crash. No study decides an individual case, but it does explain why a truck crash attorney puts the logs near the front of the line.
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. A preservation letter does not prove what existed, but it gives the company notice, and evidence destroyed after notice can lead to spoliation sanctions in many courts.
Filing deadlines and comparative fault
Each 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 a recovery by the injured person's share of fault.
