A bakery owner was killed when his Tesla Model Y struck the side of a tractor-trailer truck pulling out of a truck stop in Warrenton, Virginia.

The tractor-trailer was turning onto a highway from a truck stop before the Tesla struck its side and went underneath the truck, killing Tesla driver Pablo Teodoro III. Local police said the driver of the truck, Leroy Kenneth, was cited for reckless driving in connection with the crash. 

The incident led to an investigation by the US National Highway Traffic Safety Administration (NHTSA) into the incident, which suspected the vehicle was relying on its Autopilot driver assistance system.

Shortly afterwards, the NHTSA opened (pdf) an investigation into Tesla's Autopilot system following multiple incidents involving into parked emergency vehicles.
