Why does a case against a fatigued big rig driver often unfold so differently in court than a case against a driver who was texting? The answer comes down to what each type of claim is actually built on. Truck driver fatigue cases and distracted driving cases both involve a driver who was not fully focused on the road, but the evidence, the regulations, and even who you may be able to hold responsible can look very different. If you were hurt in a crash in El Paso and are trying to understand your legal options, knowing these differences can help you set realistic expectations for how your case may proceed.
Fatigue Claims Often Start With a Federal Rulebook
Commercial truck drivers operate under Hours of Service regulations enforced by the Federal Motor Carrier Safety Administration, which cap driving time and require rest periods to prevent fatigue-related crashes. Property-carrying drivers generally cannot drive more than 11 hours within a 14-hour on-duty window after 10 consecutive hours off duty, and weekly on-duty time is capped at 60 or 70 hours depending on the carrier’s schedule.
Since these limits are federal regulations, a violation can serve as strong evidence of negligence, and sometimes negligence per se, in a civil claim. Electronic logging devices and paper logbooks create a data trail that an attorney can request, review, and compare against dispatch records, fuel receipts, and GPS data to see whether a driver exceeded the legal limits before the crash, and whether the carrier’s own scheduling practices contributed to the violation.

Distracted Driving Claims Rely on Ordinary Negligence
There is no federal hours-of-service equivalent for passenger vehicle drivers. Instead, distracted driving claims typically rest on ordinary negligence principles and, in Texas, a specific statute. Under Texas Transportation Code Section 545.4251, drivers cannot read, write, or send an electronic message on a wireless device while operating a moving vehicle, with narrow exceptions for hands-free use and navigation.
A violation can support a negligence per se argument as well, but the proof usually looks different: cell phone carrier records obtained through a subpoena, witness accounts, and sometimes vehicle infotainment data, rather than the federally mandated logs a trucking case relies on.
Who You Are Pursuing Can Differ
In a fatigue case, the trucking company itself is frequently a defendant alongside the driver, since employers can be held responsible for scheduling pressures, understaffing, or incentive structures that encourage drivers to exceed safe limits. In a distracted driving case involving a passenger vehicle, the claim is typically directed at the individual driver and their auto insurance policy, since there is rarely a corporate employer setting the schedule.
Evidence Preservation Moves on Different Timelines
Trucking companies are required to retain certain records for limited periods, which means evidence like electronic logs can be requested and preserved quickly after a crash.
Cell phone records tied to a distracted driving claim are subject to carrier retention policies and typically require a subpoena, so timing matters in both types of cases, just for different reasons and different custodians of the evidence. If you are unsure whether key evidence in your case is still available, it is worth asking sooner rather than later.
