A 60-year-old man killed in a solo vehicle crash on Highway 101 in north Santa Rosa was driving a Mini Cooper when he drifted out of his southbound lane, off the westbound shoulder and into a small oak tree near the Hopper Avenue offramp, the CHP said.
A passerby pulled the man from his car and attempted to revive him using CPR, CHP Officer Jon Sloat said.
Rincon Valley firefighters took over life-saving efforts, but the man did not survive, Sloat said.
Authorities were withholding his name pending notification of his next of kin, Sloat said. He was believed to be a southern California resident, he said.
Sloat said the investigators were looking into whether a medical condition may have caused him to drift off the road.
The 12:54 p.m. incident closed the slow lane and the off-ramp for about an hour, but all emergency vehicles and wreckage were moved to the shoulder by 2 p.m., Sloat said.
Investigators are seeking witnesses to the crash and ask that anyone who saw it call the CHP at (707) 588-1400.
