“Vehicle 1 (V-1) was a tractor/trailer combination vehicle traveling eastbound on the driveway access to 14095 SR 7 (Pero Farms) preparing to turn left onto SR 7. Vehicle 2 (V-2) was traveling southbound on SR 7 within the outside lane approaching Pero Farms. After V-1 came to a brief stop at a stop sign, V-1 entered the southbound lanes of SR 7 pulling into the path of V-2. V-2 struck the driver side of V-1’s trailer resulting in the roof being sheared off as it passed underneath the trailer. V-2 continued southbound and came to a final rest approx 3/10th of a mile south of the collision. The driver of V-2 was pronounced deceased on scene.”
The preliminary NTSB report [2] does not provide any more precise detail of the timeline, except to acknowledge that front facing video does exist, and that neither AutoPilot or the driver attempted to stop or evade the tractor-trailer.
As the Tesla approached the private driveway, the combination vehicle pulled from the driveway and traveled east across the southbound lanes of US 441. The truck driver was trying to cross the highway’s southbound lanes and turn left into the northbound lanes. According to surveillance video in the area and forward-facing video from the Tesla, the combination vehicle slowed as it crossed the southbound lanes, blocking the Tesla’s path.... Neither the preliminary data nor the videos indicate that the driver or the ADAS executed evasive maneuvers.
