Breaches of the federal limits on how long a commercial driver may drive — relevant because fatigue causes crashes and violations show carrier practice.

Federal regulations limit driving time, on-duty time, and require rest breaks and off-duty periods for commercial drivers. The purpose is fatigue prevention.

Why they matter in a case. A driver over hours is evidence of fatigue. More importantly, a pattern of violations across a carrier's fleet supports a direct claim against the carrier for its own conduct — negligent supervision, or a system that pressures drivers to exceed limits.

Where the evidence lives. Electronic logging devices record duty status automatically, which made falsification harder. Supporting documents — fuel receipts, toll records, delivery times, dispatch communications — can corroborate or contradict the logs.

The recurring discovery fight is over the scope of records produced. Carriers resist producing fleet-wide data. Whether that's obtainable depends on the theory pleaded, which is a reason to consider a direct negligence claim early rather than only a vicarious one.

Log falsification, where it appears, is significant beyond the fatigue question — it goes to credibility and to the carrier's culture.

The logs and the fuel receipts should agree. When they don't, that's the case. ---
