Driver Fatigue and Hours of Service Rules in Tractor-Trailer Crash Claims
When a semi-truck crash happens near the end of a long shift, an early question is whether the driver was within the federal hours-of-service limits. Fatigue rarely leaves skid marks, so the answer usually comes from records rather than the roadway. A truck accident attorney reviewing one of these cases will usually compare the driver's logs with every other record of the trip.
What the federal hours-of-service rules require
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 that run through 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. 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, although a 34-hour restart starts the count over.
The regulations also include exceptions. Under the sleeper berth provision, a driver can 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 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. An electronic log is harder to falsify than a paper one, but a log alone is rarely the whole story. Experienced 18-wheeler accident lawyers know that edits, unassigned driving time and malfunction reports deserve a close look.
A thorough review compares the ELD data with the supporting documents that 49 CFR 395.11 requires trucking companies to keep, including bills of lading, dispatch https://atlantatruckaccidentlawyers.wiki/i-285-perimeter/ records, expense receipts, fleet management messages and payroll records. GPS and telematics data, toll transponder records, scale tickets and data from the engine control module (ECM) can show where the truck really was and when it moved. When those records disagree with the log, the gap itself becomes evidence.
Why the trucking company matters
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, whatever the log shows. Dispatch schedules that cannot be met legally and pay structures that reward speed can point to 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 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 commercial truck accident lawyer 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. That is one reason a truck accident attorney will often send 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 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 differ from state to state. Most states also apply comparative negligence, which can reduce what an injured person recovers by that person's share of fault.
