The collision, which involved five cars total, occurred shortly after 4:30 a.m. on the 5 Freeway north of Jamboree Road, according to the California Highway Patrol’s incident log.

The victims were both in a small Toyota that was “t-boned” on the driver’s side, Capt. Steve Concialdi of the Orange County Fire Authority said.

They were identified only as a woman in her mid-40s and a man in his mid-50s, according to Concialdi.

Four people were transported to the hospital, Concialdi said. Their conditions were not immediately known, but their injuries were all considered non-life-threatening.

One other person was injured, but refused treatment, according to Concialdi.

Two of the damaged vehicles remained at the scene of the crash nearly two hours after the collision, aerial video showed.

A SigAlert was issued shortly before 5:00 a.m., the incident log stated.

Three left lanes, including the carpool lane, were shut down, according to the Orange County CHP.

The lanes remained closed for more than hours before the SigAlert was canceled around 9:30 a.m., according to the incident log.

Traffic on the northbound side of the 5 Freeway was backed up for at least two miles at one point, video showed.

The cause of the crash was under investigation.
