What Happened

​​​​This information is preliminary and subjec​t to change.

​On Saturday, February 24, 2024, about 9:50 p.m. central standard time, a 2022 Ford Mustang Mach-E electric-powered sport utility vehicle occupied by a 44-year-old driver was traveling east on Interstate 10 (I-10) in San Antonio, Bexar County, Texas, when it collided with the rear of a stationary 1999 Honda CR-V occupied by a 56-year-old driver. The Ford was approaching Woodlake Parkway and was in the center lane of the roadway when it encountered the Honda. This section of I-10 consisted of six traffic lanes, three each in the west- and eastbound directions. The opposing lanes were divided by a concrete median barrier and the posted speed limit was 70 mph. Following the collision, the Honda overturned and came to rest in the left lane. The Ford continued to the east and came to rest in the right lane. The weather was clear, and roadway lighting was present in this section of I-10. As a result of the crash, the driver of the Honda was fatally injured, and the Ford driver sustained minor injuries.

A witness who had been traveling in the center lane of eastbound I-10 in front of the Ford reported that she encountered the stopped Honda in the center lane and that the vehicle’s tail or hazard lights were not illuminated. The witness changed lanes to the right to avoid striking the vehicle and later, in her rearview mirror, saw another vehicle strike the stopped Honda.

The Ford was equipped with numerous advanced driver assistance systems, including those providing partial automation capabilities that Ford calls “BlueCruise.” Based on data obtained from the vehicle, the driver had been operating the vehicle in BlueCruise mode before the crash.

Parties to the National Transportation Safety Board (NTSB) investigation are:

  • The San Antonio Police Department
  • Ford Motor Company

All aspects of the crash remain under investigation as the NTSB determines the probable cause, with the intent of issuing safety recommendations to prevent similar crashes.
