NTSB More details about the fatal Tesla Autopilot crash in May 2016 were released on Monday. 
 
 The National Transportation Safety Board began its investigation into the crash last July. While the probe is still underway, the agency has published about 500 pages of the data it had collected about the crash, including technical reports, transcripts, and images. 
 
 Here are some of the new details included in the report: 
 
 There was no evidence that Joshua Brown, the driver of the Model S, was using his mobile phone or another electronic device when the crash occurred, as some initial reports suggested. 
 
 During the last 41 minutes of Brown's trip, the Model S was in Autopilot for 37.5 minutes. Brown had his hands off the wheel for a total of 37 minutes during the time the car was in Autopilot. 
 
 The Model S displayed the visual warning "hold steering wheel" seven times during the trip. Six of those were followed by auditory warnings. 
 
 The Model S was driving 74 mph on the highway when it was struck by a semitruck. ||||| Page Content 
 
 WASHINGTON (June 19, 2017) – As part of its ongoing investigation into the fatal 2016 highway crash involving a Tesla Model S and a tractor-semitrailer truck near Williston, Florida, the National Transportation Safety Board on Monday opened the accident docket, releasing more than 500 pages of information.

 The docket includes reports that cover various aspects of the investigation, including highway design, vehicle performance, human performance, and motor carrier factors. The crash reconstruction report, also included in the docket, provides a description of the crash sequence. The docket also includes interview transcripts and summaries, photographs, and other investigative material. 
 
 The docket contains only factual information collected by NTSB investigators; it does not provide analysis, findings, recommendations, or probable cause determinations. No conclusions about how or why the crash occurred should be drawn from the docket. Analysis, findings, recommendations, and probable cause determinations related to the crash will be issued by the Board at a later date. 
 
 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.

– The government has released its report on the first-ever fatal self-driving car accident, and it shows that human involvement is required even when using the technology of the future. Last May, Joshua Brown collided with a left-turning truck on a divided highway near Williston, Fla., while his Tesla Model S sedan was in Autopilot. On Monday, the National Transportation Safety Board released 500 pages of findings about the accident, including a big one: During his trip, Brown ignored seven visual warnings to put his hands on the wheel, six of which were followed by a chime, reports Reuters. During a 37-minute stretch when he was supposed to be controlling the wheel, he did so for only 25 seconds. The report exonerated Brown on one thing: It found that he didn't seem to be watching a movie when the crash happened, as some reports had suggested. "Unequivocally false," says the family lawyer, saying the movie theory should be laid to rest. At the time of the accident, Tesla released a statement saying neither the autopilot system nor Brown “noticed the white side of the tractor trailer against a brightly lit sky, so the brake was not applied.” According to the report, the truck should have been visible to Brown for at least seven seconds, but the driver "took no braking, steering or other actions to avoid the collision." Less than two minutes before the accident, Brown had set the cruise control to 74 mph, nine miles per hour over the speed limit. Since the accident, Tesla has upgraded its Autopilot feature, which will now shut down if a driver fails to respond to audible warnings.
