What Happened

​This information is preliminary and subject to change.  Release Date 7 May 2024

​​On Sunday, March 3, 2024, about 3:20 a.m. eastern standard time, a 2022 Ford Mustang Mach-E electric-powered sport utility vehicle was traveling north in the left lane on Interstate 95 (I-95) in Philadelphia, Pennsylvania. The vehicle was equipped with advanced driver assistance systems, including those providing partial automation capabilities that Ford refers to as “BlueCruise.” Vehicle-based data indicated that the vehicle’s 23-year-old driver was using BlueCruise as it approached mile marker 26.8. At this location, I-95 consisted of six traffic lanes, three each in the north- and southbound directions. The opposing lanes were divided by a concrete median barrier and the posted speed limit was 45 mph. 

The Ford encountered two passenger vehicles that were stopped in the travel lanes of I-95. The Ford collided with the rear of one of the stationary vehicles, a 2012 Hyundai Elantra, which was attended by a 20-year-old driver. The Hyundai then collided with the rear of the other stationary vehicle, a 2006 Toyota Prius, attended by a 21-year-old driver. At the time of the crash, the Hyundai driver was standing outside the driver’s door of the vehicle while the Toyota driver was standing near the front of the Hyundai. As a result of the crash, the drivers of both the Hyundai and Toyota were fatally injured. The Ford driver sustained minor injuries.

At the time of the crash, the weather was clear and the road surface was dry.

​​Parties to the NTSB investigation include:

  • ​Pennsylvania State Police​
  • Ford Motor Company

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