UPDATE, 7:25 a.m. Friday: A man who CHP officers said walked into oncoming traffic on Thursday afternoon has died of his injuries.
The 49-year-old San Luis Obispo resident, who was not identified, was pronounced dead about 3:40 p.m. Thursday.
He had been transported to Sierra Vista Regional Medical Center with major injuries after the incident, which happened about 3 p.m. at southbound Highway 101 just south of the San Luis Bay Drive interchange.
UPDATE: A CHP captain at the scene of the collision said a man in his 40s appears to have intentionally stepped into the path of a big-rig truck.
Capt. Bill Vail said the CHP was called at 3:03 p.m. that a traffic accident had occurred on southbound 101 at the Avila Beach Drive interchange.
Vail said a man drove his Ford F-150 pickup to the spot, pulled over to the side of the highway, then got out and walked into the path of the semi truck.
Paramedics took the man to Sierra Vista Regional Medical Center in San Luis Obispo. His name was not given by the CHP, and his condition was not known.
The Ford was registered to an owner from Paso Robles, Vail said. He did not identify the owner.
An Oceano resident, Hector Navarro, was driving the big rig for Express Global Systems. He was not available to interview.
The incident has caused traffic to back up to the Los Osos Valley Road interchange.
