Tony Edward Reyes was identified as the motorist who died just before 12:30 a.m. on the freeway near Marsh Road and near the city of Menlo Park.
Reyes was headed north on the highway when his Chevrolet Trailblazer skipped off of the fourth and fifth lanes and hit the right-side sound wall.
Reyes then got out of his disabled car and stood in a lane where he was struck by a Jeep Liberty, driven by Romeo Tutop, 31, of San Jose.
The crash remains under investigation, CHP Officer Art Montiel said.
A sig-alert issued on a stretch of the freeway north of Marsh Road at 12:47 a.m. was canceled shortly after 3:30 a.m., according to the CHP.
