The collision took place on Highway 20 west of Sayre Avenue in Nice at 4:22 a.m., according to Josh Dye, public information officer for the CHP's Kelseyville office.
Clearlake resident Michelle Paterson was driving westbound on Highway 20 when she encountered Martha Bertolino in the roadway, Dye reported.
Paterson's vehicle struck Bertolino, who suffered a broken leg and various lacerations, said Dye.
Bertoleno was flown by REACH helicopter to Santa Rosa Memorial Hospital for treatment, according to Dye's report.
CHP's incident logs reported that a blood draw was conducted on Bertolino, which Dye confirmed.
Dye said the CHP is still investigating why Bertolino was in the roadway at that hour.
