NTSB to Vote Next Month on Cause of Fatal Tesla Autopilot Crash

A meeting will be held next month by the National Transportation Safety Board to determine the probable cause of a fatal Tesla crash last year near Williston, Florida.

One person was killed when a 2015 Tesla Model S collided with a 2014 Freightliner Cascadia semitractor-trailer on US Highway 27A. The Tesla’s Traffic-Aware Cruise Control and Autosteer lane-keeping assistance features were being used by the driver at the time of the crash. The Tesla was traveling at 74 mph just prior to impact.

According to a release from NTSB, a team of five investigators traveled to Williston to conduct the on-scene phase of the investigation, using three-dimensional laser scanning to document the crash location, the damaged trailer and the damaged car. As the investigation progressed, the team expanded to cover nine areas of inquiry.

The NTSB released a preliminary report on the crash in May. And, in June, said the driver kept his hands off the wheel for extended periods of time despite repeated automated warnings not to do so. Further, NTSB said the drivers hands were on the wheel for just 25 seconds during a 37-minute period that Autopilot was engaged.
