Hours of Service Violations in Tractor-Trailer 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 leaves little physical trace at a crash scene, 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, one part of the Federal Motor Carrier Safety Regulations that run through 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. Driving is not allowed 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, and a 34-hour restart starts the count over.
The regulations also include 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 covers drivers who remain inside a 150 air-mile radius and finish within 14 hours. Whether any exception fits is a factual question, and the trucking company typically has the records that answer it.
Finding an hours-of-service violation
Most drivers required to keep records of duty status now rely on an electronic logging device (ELD) instead of a paper logbook. According to the FMCSA, an ELD synchronizes with the vehicle engine to automatically record driving time, and Congress mandated the ELD rule as part of MAP-21. Electronic logs are harder to falsify than paper logs, yet the log alone is seldom the whole story. Experienced truck crash attorneys treat edits, unassigned driving time and malfunction reports as worth a close look.
A thorough 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. 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. When those records disagree https://truckaccidentlawyers.wiki/geography/united-states/ with the log, the mismatch itself becomes evidence.
Why the trucking company matters
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 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, such as negligent supervision, alongside 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 commercial truck accident lawyer puts the logs near the front of the line.
Preserving the evidence early
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. The letter does not prove what existed, but it gives the company notice, and evidence destroyed 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 use comparative negligence, which can reduce a recovery by the injured person's share of fault. This is general information and not legal advice, and no article can predict the result of a particular claim.
