CHP officers arrested three individuals suspected of driving under the influence in separate incidents around Sonoma County on Friday morning, Sgt. Dave Derczo said.

A sheriff’s deputy responding to a black Nissan parked on the shoulder of Highway 101 near the northbound Mendocino Avenue onramp found the driver staring straight ahead and unresponsive. Upon seeing the deputy, the driver climbed into the back seat and put on headphones, Derczo said. A CHP officer arrived to assist the deputy, and the driver remained unresponsive to requests to exit the vehicle.

The officer broke the back window of the car and dragged the driver out. Officers found jars of marijuana and arrested the driver on suspicion of driving under the influence of marijuana. Northbound Highway 101 was briefly closed about 8:30 a.m. while they arrested the driver, Steven Ross, 41, of West Sacramento.

Earlier, at about 6:50 a.m., a CHP officer responded to a Jeep Wrangler that had traveled off Highway 101 and crashed into a redwood tree on southbound 101 north of River Road. The driver, William Corley, 54, of Laytonville, was arrested on suspicion of driving under the influence of methamphetamine, Derczo said.

And at 9:20 a.m., a silver Audi was involved in a solo- vehicle crash on Highway 116 between Forestville and Guerneville. The car was on its roof and blocking traffic when an officer arrived. The driver, Chad Church, 32, of Guerneville, was arrested on suspicion of driving under the influence of opiates.
