Santa Rosa-area CHP officers arrested 10 people on suspicion of drunken driving over the weekend, seven of whom have prior DUIs.

Just before 11 a.m. Friday, a CHP officer spotted a Nissan Xterra weaving onto the shoulder of Highway 101 near River Road. After exiting the highway, the driver narrowly avoided a power pole before stopping for the officer, CHP Officer Jon Sloat said.

Driver Catherine Crain, 38, of Petaluma was arrested on suspicion of DUI and violating probation. Sloat said she had two DUI convictions last year and is required to drive a vehicle with an ignition interlock device, which the Nissan did not have.

At 3:30 a.m. Saturday, three 911 callers reported a DUI driver on northbound Highway 101 near Cotati. Officers stopped the vehicle at Rohnert Park Expressway, Sloat said.

Driver Torry Lynn Mercuri, 36, of Santa Rosa failed sobriety tests and was arrested on suspicion of DUI. She has two DUI convictions and is on probation, Sloat said.

Later Saturday, a speeding motorcycle splitting traffic lanes caught the eye of a CHP officer monitoring traffic on 101, Sloat said.

The officer said he paced the Yamaha motorcycle at 105 mph before the rider pulled over. Roger Vigil, 23, of Healdsburg was arrested on suspicion of DUI and speeding while impaired. Sloat said Vigil has one DUI conviction.

Just after 9 p.m. on Sunday, officers responded to a crash on southbound 101 south of Corona Road and found a Dodge Dakota had run off of the roadway and overturned.

Driver Isidro Torres, 45, of Petaluma was arrested at Santa Rosa Memorial Hospital on suspicion of drunken driving and violating probation. He has two DUI convictions, including one from January, and multiple license suspensions, Sloat said.
