Tesla has begun deliveries of its long-awaited electric semi-truck, opening its first mass-production facility outside of Reno, Nevada.

The company’s CEO Elon Musk touted the new trucks in a video at the facility launch, calling the vehicle “a revolutionary truck that is capable of carrying the heaviest loads.” The company first unveiled the idea of the electric big-rig in 2017, cutting the ribbon on the production facility in Sparks, Nevada, nearly a decade later.
