Hours of Service Violations in Truck Accident Claims

Driver Fatigue and Hours of Service Rules in Truck Accident Claims

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 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.

How the federal hours-of-service rules work

The Federal Motor Carrier Safety Administration (FMCSA) sets 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 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. 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 begins a new period.

The rules also contain 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.

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. The FMCSA explains that 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, but a log alone is rarely the whole story. Experienced truck accident attorneys know that edits, unassigned driving time and malfunction reports deserve a close look.

A careful review compares the ELD data with 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 https://truckaccidentlawyer.wiki/topics/evidence/ data from the engine control module (ECM) can show where the truck actually 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. Dispatch schedules that cannot be met legally and pay structures 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 made it more likely that the driver would be found to have precipitated the crash. A study cannot decide an individual case, but it does explain why a commercial truck accident lawyer treats the logs as a priority.

Preserving the evidence early

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 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 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 differ from state to state. Most states also apply comparative negligence, which can reduce a recovery by the injured person's share of fault.
