A Lexus sedan was stopped at the center divider just north of Edgewood Road near Redwood City Friday around 3:10 p.m. when it was struck by a black Volkswagen that swerved into the center divider, CHP Officer Art Montiel said.
Three people in the Lexus, a woman in her late 40s, a 21-year-old woman and a 28-year-old man, were pronounced dead at the scene, Montiel said.
A fourth person in the Lexus, a 56-year-old Santa Clara man, survived the crash and was taken to the hospital with injuries, Montiel said.
The driver of the Volkswagen, a man in his early 80s, was taken to the hospital with minor injuries.
He is expected to be arrested on suspicion of vehicular manslaughter upon his release due to reports that he was speeding at the time of the crash and due to the large number of people killed, Montiel said.
The crash shut down four lanes, leaving only the far right lane open and backing traffic up for miles.
Montiel said the vehicles were being towed away as of shortly after 6 p.m.
