A CalStar medical helicopter was dispatched to transport a critically injured man, the driver of the van, to Santa Barbara Cottage Hospital. The female driver of the Toyota 4Runner died of her injuries, Eliason said.

Personnel from Santa Barbara County Animal Services also were sent to the scene after one small dog in the 4Runner also died in the collision, Eliason said.

Highway 1 between Lompoc and Gaviota was closed in both directions due to the crash, the CHP said, with drivers diverted to Highway 246. Officers from the CHP’s Buellton Area Office will investigate the incident. Additional information was not immediately available.
