Hours of Service Violations in Tractor-Trailer Crash Claims
By @emilianodmbq904
When a semi-truck crash happens near the end of a long shift, one of the first questions is whether the driver was within the federal hours-of-service limits. Fatigue leaves little physical trace at a crash scene, which is why the answer tends to come from records instead of the road itself. A tractor-trailer crash lawyer looking at one of these claims will usually compare the driver's logs with 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, one part 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. The driver must take a 30-minute break 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, and a 34-hour restart begins a new period.
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 are released within 14 hours. Whether an exception applies is a question of fact, and the trucking company typically has the https://atlantatruckaccidentlawyers.wiki/topics/local-firms/ 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 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, but a log alone is rarely the whole story. Experienced truck crash attorneys treat edits, unassigned driving time and malfunction reports as worth 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. 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. When those records disagree with the log, the mismatch itself becomes evidence.
Responsibility beyond the driver
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, whatever the log shows. Delivery schedules that cannot be met legally and pay plans that reward speed can support 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 does explain why a commercial 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. 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 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 differ from state to state. Most states also use comparative negligence, which can reduce what an injured person recovers by that person's share of fault.
