LAKE COUNTY, Calif. — The California Highway Patrol released additional information about a crash that killed a Middletown bicyclist on Monday evening.

The victim was a 73-year-old Middletown man whose name was not released in a Tuesday report pending the notification of next of kin.

The CHP’s Clear Lake Area office reported that it received a call at 5:08 p.m. Monday about a call about a traffic collision involving a vehicle and a bicyclist on Highway 175 south of Dry Creek Cutoff Road.

When CHP officers arrived at the scene, they determined that the crash victim was riding his bicycle on Dry Creek Cutoff Road, approaching Highway 175.

Richard Whalin, 60, of Yuba City, was driving a 2019 Ford F-350 dually truck, towing a 2018 Carson utility trailer, eastbound on SR-175, approaching Dry Creek Cutoff Rd.

For reasons that the CHP said are still under investigation, the bicyclist entered the roadway directly ahead of Whalin, who attempted to swerve to avoid hitting him.

The CHP said the vehicle and bike collided, resulting in the bicyclist sustaining major injuries.

South Lake County Fire Protection District firefighters attempted lifesaving measures but the man died of his injuries at the scene, the CHP said.

The CHP said the bicyclist was not wearing an approved bicycle helmet at the time of the collision.

Whalin was not injured due to the collision and remained on scene to cooperate with the investigation, the CHP said.

CHP Sgt. Joel Skeen established incident command. Caltrans, the Lake County Sheriff’s Office and South Lake County Fire responded to the scene to provide assistance.

The CHP said traffic on Highway 175 was diverted onto Dry Creek Cutoff Road to facilitate the investigation.

Neither drugs nor alcohol were suspected as factors in the crash, the CHP said.
