A man standing outside of his disabled vehicle on the shoulder of Interstate 805 in Sorrento Valley was hit by a car and suffered serious head injuries.
CHP Investigators say the victim was standing on the driver side of his Nissan 350Z on the shoulder of the freeway when he and his car were hit by a Mercedes. The impact launched the victim more than 100 feet, officers said.
"We don't know why the blue vehicle was stopped in the lane or why the driver got out," said Sgt. Steve Jio with CHP.
A second vehicle then hit the Nissan and another car was damaged by debris on the road.
Witness told investigators that the 350Z driver was racing with another car before he decided to pull over on the side of the road for unknown reasons. CHP said the car the victim was racing wasn't involved in the crash and was not at the scene.
The crash set off an hours-long Sig Alert for northbound lanes near Sorrento Valley Boulevard and the I-5 transition just after 3 p.m.
The victim was transported to Scripps Mercy Hospital in La Jolla. No one else was injured, CHP officers said.
Traffic was rerouted to State Route 56 before I-805 was reopened at around 5:15 p.m.
