A Tehachapi woman was killed and a man was critically injured in a head-on crash that sparked a vegetation fire Saturday night on Highway 166. 

At approximately 6:45 p.m. Saturday, Santa Barbara County firefighters and California Highway Patrol officers were dispatched to the incident about 46 miles east of Highway 101.

A Harley-Davidson motorcycle and a Subaru SUV collided, igniting a grass fire nearby.

The motorcycle’s passenger, a 40-year-old woman from Tehachapi, was pronounced dead by medical staff at the scene, the CHP said.

Release of her name was pending notification of family members.

A 52-year-old man from Tehachapi was critically injured and taken by Calstar medical helicopter to Santa Barbara Cottage Hospital.

Two people in the Subaru, a 68-year-old man and a 64-year-old woman, both from Palmdale, received minor injuries, the CHP said.

Santa Barbara County firefighters along with counterparts from Cal Fire and the Los Padres National Forest Service contained the fire to less than 3 acres. 

The cause of the collision remains under investigation by CHP officers from the Santa Maria area.
