Driver Fatigue and Hours of Service Rules in Tractor-Trailer Crash Claims
When a tractor-trailer crash happens late in a long run, one of the first questions 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 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) 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. 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. Across a 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 begins a new period.
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 covers drivers who remain inside a 150 air-mile radius and finish within 14 hours. Whether an exception applies is a question of fact, and the trucking company usually holds the records that answer it.
How hours-of-service violations come to light
Most drivers required to keep records of duty status now rely on an electronic logging device (ELD) rather than paper logs. The FMCSA explains that 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, 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, such as bills of lading, dispatch records, expense receipts, fleet management messages and payroll records. Telematics and GPS data, toll transponder records, scale tickets and data from the engine control module (ECM) can https://atlantatruckaccidentlawyers.wiki/downtown-connector/ show where the truck actually was and when it moved. When those records disagree with the log, 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 prohibits 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 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 increased the likelihood 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.
Preserving the evidence early
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 tractor-trailer crash 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 destroying evidence after notice can lead to spoliation sanctions in many courts.
Filing deadlines and comparative 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 a recovery by the injured person's share of fault.
