Hours of Service Violations in Semi-Truck Crash Claims
After a tractor-trailer crash on a long-haul route, an early question is whether the driver was within the federal hours-of-service limits. Fatigue rarely leaves skid marks, which is why the answer tends to come from records instead of the road itself. A tractor-trailer crash lawyer reviewing one of these cases usually starts by comparing the driver's logs against 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 found in 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. The driver may not drive beyond the 14th consecutive hour after coming on duty, and off-duty time does not https://archerogth474.brightpathdigest.com/posts/eld-records-and-ecm-black-box-data-after-a-truck-accident 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 begins a new period.
The rules also contain 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 are released within 14 hours. Whether an exception applies is a question of fact, and the trucking company typically has 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 as part of 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 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. Telematics and GPS data, toll transponder records, weigh station records and data from the engine control module (ECM) can show where the truck really was and when it moved. If those sources disagree with the logs, the gap itself becomes evidence.
When the company shares responsibility
Part 395 places duties on more than the driver. The rules bar a trucking company from requiring or permitting 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. Delivery schedules that cannot be met legally and pay plans that reward speed can support 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 increased the likelihood that the driver would be found to have precipitated the crash. A study cannot decide an individual case, but it explains why a commercial truck accident lawyer 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 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 puts the company on notice, and evidence destroyed after notice can lead to spoliation sanctions in many courts.
Deadlines and shared 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 what an injured person recovers by that person's share of fault.
