WASHINGTON, Feb 8 (Reuters) - The U.S. National Transportation Safety Board said on Wednesday the probable cause of an April 2021 Tesla crash that killed the driver and a passenger was the drivers excessive speed and failure to control the 2019 Tesla Model S.

The NTSB cited the driver's impairment from alcohol intoxication in combination with the effects of two sedating antihistamines. Local police had said in 2021 they believed the crash occurred with no one in the driver's seat, raising questions about Tesla's driver-assistance systems. The NTSB probable cause findings did not reference Autopilot or any other advanced system. (Reporting by David Shepardson; Editing by Leslie Adler)
