A 2014 Tesla Inc. Model S that crashed into an unoccupied fire truck along Interstate-405 in Culver City, Calif., in January 2018 had its autopilot engaged, according to a National Transportation Safety Board report.
The autopilot was engaged for a total of 29 minutes in the 66-minute trip. When the crash occurred, autopilot was active and had been engaged for 13 minutes, 48 seconds, the NTSB said.
The driver also had his hands off the steering wheel for the majority of the trip. The report said the driver did not place his hands on the steering wheel for 12 minutes, 57 seconds during the trip's final segment where a "place hands on wheel" alert was given at least four times.
Records also revealed that the driver was not using his mobile phone at the time of the crash.
The California-based electric-vehicle maker became the focus of regulatory investigations last year over a number of crashes involving the use of its autopilot self-driving technology.
In March, the NTSB and the National Highway Traffic Safety Administration launched a probe into two fatal Tesla crashes in Florida over the week of Feb. 25.
Tesla did not immediately respond to S&P Global Market Intelligence's request for comment.
