Hours of Service Violations 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, so the answer usually comes from records rather than the roadway. A truck accident attorney 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) 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. 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, 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 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 usually holds the records that answer it.

How investigators spot hours-of-service violations

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 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 know that edits, unassigned driving time and malfunction reports deserve 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. 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. If those sources disagree with the logs, the gap itself becomes evidence.

Why the trucking company matters

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. 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 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 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. 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 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 apply 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.
