Driver Killed When Truck Rolls Down Embankment of I-15

A Garden Grove man was killed early Monday when the tractor-trailer he was driving rolled down the embankment of southbound Interstate 15 in Wildomar, according to authorities.

The 55-year-old driver, whose identity has not been released, was driving in the No. 3 lane just south of Olive Street at an undetermined speed about 2 a.m., according to a California Highway Patrol news release. The vehicle veered onto the right shoulder, collided with a concrete wall, then traveled about 75 feet down a dirt embankment before rolling over on its side.

The vehicle collided with a telephone pole at that point. The driver, who was not wearing a seat belt, was ejected out the right side passenger window, becoming pinned under the vehicle. He was pronounced dead at the scene.

The accident is under investigation.
