A fatal crash involving a Tesla Semi is under investigation in Nevada after two people were killed and another was seriously injured in what appears to be the first deadly collision involving the battery-electric Class 8 truck.
The crash happened last Sunday morning on U.S. Highway 50 in Dayton, about 40 miles east of Reno. According to the Nevada State Police Highway Patrol, the Tesla Semi collided with two passenger vehicles that were stopped at a traffic light-controlled intersection.
Two occupants of one of the vehicles died at the scene, while a third person sustained critical injuries and was transported by air ambulance to the hospital. The Tesla Semi driver was not injured.

The victims were identified by local publication Record-Courier as Sergio and Jennifer Villanueva, a married couple whose vehicle, an old Volkswagen Beetle, was reportedly struck from behind by the Tesla Semi while waiting at the intersection.
Authorities have not determined what caused the crash, and the investigation remains ongoing. However, the Lyon County Sheriff's Office said preliminary information gathered at the scene suggests the truck driver may have fallen asleep before the collision.
"Preliminary statements obtained at the scene suggest the driver of the semi may have fallen asleep," the sheriff's office said.
Along with the driver, officials have not yet identified the carrier or company operating the vehicle. No charges have been filed as investigators continue to examine the circumstances surrounding the crash.
While they are examining whether driver fatigue played a role in the collision, there is currently no indication that Tesla's driver-assistance technology was involved. Why? Because the Tesla Semi is not equipped with the company's Full Self-Driving (FSD) system for customer use, despite Tesla describing the truck as being "designed for autonomy" in the future.
Last week, a Tesla Semi was spotted testing with FSD external hardware, so we know the tech is coming. Eventually.
The crash also raises questions about why the Tesla Semi's Automatic Emergency Braking (AEB) system did not intervene to help prevent or mitigate the collision. In addition to AEB, the Semi is equipped with other active safety features, including Forward Collision Warning. It remains unclear whether either system detected the stopped traffic or activated before impact.
Tesla has not publicly commented on the crash or the ongoing investigation.
