KELSEYVILLE – A Redwood Valley couple suffered injuries in a Saturday crash involving three vehicles on Highway 29.

Dennis Scoles, 66, and Viola Scoles, 65, were transported to the hospital following the crash, which occurred at around 2:50 p.m. on Highway 29 north of Highway 175 to Cobb, according to the California Highway Patrol.

The CHP said Dennis Scoles had stopped his 2001 Volvo V-70 station wagon on the northbound shoulder of Highway 29 within a private driveway entrance, facing in a southwesterly direction and preparing to make a U-turn onto southbound Highway 29.

Kay White, 49, of Sacramento, was driving a 1998 Peterbilt tractor truck with two flatbed trailers following a car, traveling northbound on Highway 29 at a stated speed of about 45 to 50 miles per hour, approaching Scoles' position.

Behind White was Olivia Peregrina, 26, of Cobb in a 2002 Dodge Neon with a 3-year-old boy in the car with her, the CHP said.

When the car ahead of White passed Scoles, he is reportedly to have suddenly pulled into White's path, according to the report.

The CHP said White aggressively applied the truck's brakes and attempted to avoid Scoles but couldn't.

The front of the Peterbilt struck the Volvo's driver's side, causing the Volvo to spin off the road and onto a dirt area south of the highway where it came to rest on its wheels, facing in a southerly direction.

The CHP said Peregrina noticed quite a bit of smoke created by the braking Peterbilt and aggressively applied her own brakes.

She veered off the highway to the north to avoid striking the Peterbilt's rearmost trailer. The action caused her to run off the road onto a dirt embankment, suffering a flat right front tire.

White safely brought the Peterbilt to rest on the highway's northbound shoulder, the CHP said.

Both Dennis and Viola Scoles were airlifted to Sutter Santa Rosa for treatment of their injuries, the CHP reported.
