Hours of Service Violations in Semi-Truck Crash 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 truck accident lawyer looking at one of these claims usually starts by comparing the driver's logs against every other record of the trip.
How the federal hours-of-service rules work
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. 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. 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, 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 finish 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) instead of a paper logbook. According to the FMCSA, an ELD synchronizes with the vehicle engine to record driving time automatically, 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 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, 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 show where the truck really 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 bars operating a truck while the driver's alertness is impaired by fatigue, whatever the log shows. Delivery 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 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 truck crash attorney puts the logs near the front of the line.
Acting before records are lost
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 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. A preservation letter does not prove what existed, but it gives the company https://simonjgev973.summitquill.com/posts/what-to-know-about-underride-and-jackknife-truck-crashes notice, and evidence destroyed after notice can lead to spoliation sanctions in many courts.
Deadlines and shared fault
Each 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 what an injured person recovers by that person's share of fault.
