Driver Fatigue and Hours of Service Rules in Truck Accident Claims

What a Truck Accident Lawyer Checks in a Driver's Logs

When a semi-truck crash happens near the end of a long shift, an early question 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 truck accident lawyer 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. 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 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 starts the count over.

The regulations also include 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.

How hours-of-service violations come to light

Most drivers who must keep records of duty status now use an electronic logging device (ELD) instead of a paper logbook. The FMCSA explains that an ELD synchronizes with the vehicle engine to record driving time automatically, and Congress mandated the ELD rule through MAP-21. An electronic log is harder to falsify than a paper one, yet the log alone is seldom the whole story. Experienced 18-wheeler accident lawyers know that edits, unassigned driving time and malfunction reports deserve 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, such as bills of lading, dispatch records, https://mariotdkt975.birchreport.com/posts/driver-fatigue-and-hours-of-service-rules-in-tractor-trailer-crash-claims 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 actually 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. 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. 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. A study cannot decide an individual case, but it does explain why a semi-truck accident lawyer puts the logs near the front of the line.

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 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. The 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.

Deadlines and shared 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. This is general information and not legal advice, and no article can predict how a particular claim will turn out.
