On Tuesday, November 26, 2024, at 10:02 pm, a blue Prius, occupied by two, was southbound on I-15 near milepost 354. The vehicle impacted the concrete barrier on the left shoulder and came to a rest, facing sideways on the shoulder. This was likely due to weather and roadway conditions. The adult male driver exited his car, and the adult female front passenger opened her door but remained in the vehicle. A second vehicle, a Ford Expedition, struck the male outside of his Prius and then hit the Prius head-on on the front passenger side, striking the female front passenger. The female passenger sustained fatal injuries from the impact. The male who was struck outside of his vehicle was transported in critical condition. The occupants of the Expedition did not sustain any injuries.
