Hours of Service Violations in Truck Accident Claims
When a semi-truck crash happens near the end of a long shift, one of the first questions 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 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) 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. For property-carrying drivers, the core limits are simple to state. A driver may 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. 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, and 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 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.
Finding an hours-of-service violation
Most drivers who must keep records of duty status now use an electronic logging device (ELD) instead of a paper logbook. The FMCSA explains that an ELD synchronizes with the vehicle engine to record driving time automatically, and Congress mandated the ELD rule as part of MAP-21. An electronic log is harder to falsify than a paper one, yet the log alone is seldom the whole story. Experienced 18-wheeler accident lawyers treat edits, unassigned driving time and malfunction reports as worth a close look.
A thorough review lines the ELD data up against the https://kameronkdqn741.talesignal.com/posts/black-box-ecm-and-eld-evidence-after-a-truck-accident 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. Telematics and GPS 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 mismatch itself becomes evidence.
Why the trucking company matters
The duties in Part 395 reach beyond 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. No study decides an individual case, but it does explain why a semi-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. This is one reason a tractor-trailer crash 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 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 vary by state. Most states also apply comparative negligence, which can reduce a recovery by the injured person's share of fault.
