Sergio and Jennifer Villanueva were killed in a multi-vehicle crash in Nevada that authorities say may be the first known fatal incident involving a Tesla Semi truck. The collision occurred on June 28 near Dayton in Lyon County and is currently under investigation by the Nevada State Police Highway Patrol.
Officials are still working to determine the exact cause of the crash.
According to preliminary findings from the Lyon County Sheriff’s Office, early evidence suggests the Tesla Semi driver may have fallen asleep before the crash. The incident involved three vehicles, including the Tesla Semi and two passenger cars, one of which was a vintage Volkswagen Beetle.
A third person sustained life-threatening injuries and was airlifted to hospital.
Trooper James LaRose confirmed that the Tesla Semi driver was not injured in the crash. Investigators have not yet reached a final conclusion, and authorities have emphasized that multiple factors, including driver fatigue, road conditions, and mechanical issues, remain under review as part of the ongoing probe.
