Hours of Service Violations in Semi-Truck Crash Claims
When a tractor-trailer crash happens late in a long run, an early question is whether the driver had stayed inside the federal hours-of-service limits. Fatigue rarely leaves skid marks, so the answer usually comes from records rather than the roadway. 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, one part of the Federal Motor Carrier Safety Regulations that run through 49 CFR Parts 390-399. The core limits for property-carrying drivers are simple to state on paper. A driver may 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. The driver must take a 30-minute break 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 rules also contain 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 applies to drivers who stay within 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. The FMCSA explains that an ELD synchronizes with the vehicle engine to record driving time automatically, and Congress mandated the ELD rule through MAP-21. An electronic log is harder to falsify than a paper one, yet the log alone is seldom the whole story. Experienced truck accident attorneys treat edits, unassigned driving time and malfunction reports as worth a close look.
A careful review lines the ELD data up against the supporting documents that 49 CFR 395.11 requires trucking companies to keep, including 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. When those records disagree with the log, the mismatch itself becomes evidence.
Responsibility beyond the driver
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 prohibits operating a truck while the driver's alertness is impaired by fatigue, whatever the log shows. Delivery schedules https://keeganvqxs558.keystonescope.com/posts/liability-in-commercial-truck-crash-claims-explained that cannot be met legally and pay structures 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 explains why a semi-truck accident lawyer treats the logs as a priority.
Acting before records are lost
Under 49 CFR 395.8, the minimum retention period for records of duty status and supporting documents is six months. This is one reason an 18-wheeler crash lawyer 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 destroying evidence 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 differ from state to state. Most states also use comparative negligence, which can reduce a recovery by the injured person's share of fault.
