How Hours of Service Violations Can Shape an 18-Wheeler Crash Claim
When a semi-truck crash happens near the end of a long shift, an early question is whether the driver had stayed inside the federal hours-of-service limits. Fatigue rarely leaves skid marks, which is why the answer tends to come from records instead of https://truckaccidentlawyer.wiki/topics/cargo-securement/ 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) writes the hours-of-service rules in 49 CFR Part 395, one part 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 can 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. 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 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 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 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 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, including bills of lading, dispatch records, expense receipts, fleet management messages and payroll records. GPS and telematics 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 mismatch itself becomes evidence.
Why the trucking company matters
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. Delivery 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 made it more likely that the driver would be found to have precipitated the crash. No study decides an individual case, but it explains why a semi-truck accident lawyer treats the logs as a priority.
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. This 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 gives the company 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 differ from state to state. Most states also apply comparative negligence, which can reduce what an injured person recovers by that person's share of fault.
