One woman was killed and another was seriously injured Wednesday afternoon in a collision on Highway 246 west of Solvang, according to the California Highway Patrol.

Stephen Waldman, 71, of Buellton was westbound on Highway 246 west of Skytt Mesa Drive shortly after 1 p.m. when he pulled over to the side of the road, preparing to make a U-turn, CHP Office Michael Griffith said.

A Honda CRV driven by a 73-year-old San Juan Bautista woman was following behind when Waldman made an “unsafe turn” in front of her, Griffith said.

As a result, the left front of Waldman’s Accord collided with the right rear of the CRV, Griffith said, causing the CRV to veer off the road and strike an oak tree.

The CRV driver suffered major injuries, and was taken by American Medical Response ambulance to Marian Regional Medical Center in Santa Maria, where she died of her injuries.

Her name was being withheld pending notification of relatives.

A passenger in the CRV — Charlotte Ann Buck, 73, of Duarte — suffered moderate injuries, and was taken by ambulance to Santa Barbara Cottage Hospital.

Details on her condition were not available.

Waldman was not injured in the collision, the CHP said.

Highway 246 was shut down for a time in the area of the crash.

The crash remained under investigation, and the CHP was asking that anyone with information about it contact the Buellton CHP office at 805.688.5551.
