How Hours of Service Violations Can Shape a Tractor-Trailer Crash Claim
After a tractor-trailer crash on a long-haul route, one of the first questions is whether the driver was within the federal hours-of-service limits. Fatigue rarely leaves skid marks, so the answer usually comes from records rather than the roadway. 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.
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, 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 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, although a 34-hour restart starts the count over.
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 applies to drivers who stay within a 150 air-mile radius and finish within 14 hours. Whether an exception applies is a question of fact, and the trucking company typically has the records that answer it.
Finding an hours-of-service violation
Most drivers who must keep records of duty status now use an electronic logging device (ELD) rather than paper logs. 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 accident attorneys treat edits, unassigned driving time and malfunction reports as worth a close look.
A thorough 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. Telematics and GPS data, toll transponder records, weigh station records 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 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. Dispatch schedules that cannot be met legally and pay plans that reward speed can point to claims against the company itself, including 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. A study cannot decide an individual case, but it explains 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. This is one reason a truck accident 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 destroying evidence 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 vary by state. Most states also apply comparative negligence, which can reduce a recovery by the injured person's share of fault.
