CHP officers on regular patrol arrested five motorists on suspicion of drunken driving within a span of about 20 hours ending early Thursday. The arrests included three people with prior DUI convictions, CHP officials said.

Kenneth Chase, 25, of Santa Rosa was arrested behind the wheel of a Lincoln Navigator that ran off the road on River Road near Laughlin Road at about 5:30 a.m. Wednesday, CHP Officer Jon Sloat said. Chase, who has a prior DUI conviction, told officers he fell asleep at the wheel, Sloat said. A DUI evaluation found his blood-alcohol level was about three times over the legal limit to drive, which is 0.08 percent, according to the CHP.

Wednesday night, a Santa Rosa man with four prior DUI convictions was arrested after he was spotted weaving among lanes and onto the shoulder on Highway 12 near the Highway 101 interchange, traveling slower than 40 mph, Sloat said. An officer had to help Mohinder Singh, 56, out of the Jeep Cherokee he had been driving, Sloat said. His blood-alcohol content was more than four times the legal limit, the officer said.

At about midnight, Bonnie Plevney, 52, of Guerneville was arrested after she was suspected of hitting a parked car on River Road near Highway 116 in Guerneville, Sloat said. Plevney, who has a prior DUI conviction, resisted when officers tried to arrest her, according to Sloat. Her blood-alcohol level was measured to be just under three times the legal limit to drive, he said.
