San Onofre, CALIF. - A SUV rollover caused a major traffic backup in both directions of Interstate 5 near the San Onofre border checkpoint Saturday.

According to the CHP, a 22 year old man from San Diego was driving his 2004 Ford Explorer northbound on I-5 just south of the border patrol checkpoint around 8:15a.m. when he saw traffic stopped ahead of him.

The CHP says due to his high rate of speed, he turned his vehicle to the right in order to avoid a collision. That caused his vehicle to roll several times with his four passengers inside the vehicle. 

One of those passengers, a 26 year old man from San Diego, was not wearing a seatbelt and he was ejected from the Explorer. He died at Scripps La Jolla Hospital Saturday afternoon.

Two other female adult passengers and one more male adult passenger suffered moderate to major injuries. They were taken to Scripps La Jolla, and Mission Viejo Hospital. 

The CHP says alcohol and drugs are not believed to be factors in the collision.
