SAN DIEGO (KGTV) - A driver was ejected and died after a chain-reaction crash on Interstate 15 in the Miramar area Tuesday night.
The crash happened shortly before 10:15 p.m. on southbound I-15 near state Route 163, according to the California Highway Patrol.
The CHP said a 27-year-old man was driving his Honda Civic with a 31-year-old female passenger when he suddenly changed lanes and hit a Subaru Outback before striking a Toyota Camry.
Witnesses said the Civic had been driving erratically on northbound I-15 before exiting on Miramar Way and re-entering the freeway on the southbound side.
The collision caused the Civic to veer towards the center divider, where it collided with a BMW sedan in and then struck the center divider wall, the CHP reported.
According to the CHP, the impact caused the Civic to roll and the driver -- who was not wearing a seatbelt -- to be ejected onto the freeway. The woman was restrained, the CHP said.
"He just came up out of nowhere and sideswiped me," one woman told 10News, describing the incident as another witness cried next to her.
Several Good Samaritans stopped to tend to the injured man and help the woman out of the wreckage.
The man and woman were taken to the hospital, but 10News learned the man died from his injuries. The woman suffered minor injuries, the CHP said.
Witnesses told 10News they believed the Civic's driver was under the influence, but CHP officials did not confirm if he had been drinking.
The occupants in the Outback, Camry and BMW were not hurt in the incident.
Multiple lanes on southbound I-15 were shut down for several hours due to the investigation and clean-up.
