On Saturday, May 7, 2016, a 2015 Tesla Model S 70D, traveling eastbound on US Highway 27A (US-27A) west of Williston, Florida, struck and passed beneath a refrigerated semitrailer powered by a 2014 Freightliner Cascadia truck-tractor. At the time of the collision, the truck was making a left turn from westbound US-27A across the two eastbound travel lanes. Impact with the right side of the semitrailer sheared off the roof of the Tesla. The driver and sole occupant of the Tesla died in the crash; the commercial truck driver was not injured.
The NTSB released the preliminary report for this crash on July 26, 2016.
