WASHINGTON, March 18 (Reuters) - The National Highway

Traffic Safety Administration said on Monday it has opened an

investigation into a recent Ford Mustang Mach-E fatal

crash in San Antonio, Texas where an advanced driver assistance

system is suspected of use.

On Friday, the National Transportation Safety Board opened a

separate investigation into the Feb. 24 crash, saying initial

information indicated the Ford struck the rear of a Honda CR-V

that was stationary in a traffic lane on Interstate Highway 10.

A San Antonio police report said the Ford had "partial

automation" engaged at the time of the crash.
