Rohnert Park police held a drunken driver checkpoint Saturday night, arresting three suspected intoxicated drivers and 14 others for license violations.
The screen was set up on one of the town's major routes — Rohnert Park Expressway near State Farm Drive.
Officers worked it from 7 p.m. to 1 a.m. Sunday.
During the six hours, 1073 vehicles passed through the checkpoint and officers screened 1,029 drivers.
Of those, 46 drivers were given a second look, revealing a variety of suspected offenses, officials said.
Driver Timothy Bagwell was stopped in the checkpoint at about 8:45 p.m.
He appeared to be intoxicated and was given sobriety tests and his blood-alcohol percentage showed he was .20 almost 2? times the legal limit, officials said.
About an hour later, driver Gerald Burr of Rohnert Park came through the checkpoint and was found to have a blood-alcohol amount just over the legal limit. He showed a .09 percent and was arrested but released to a sober driver.
Twenty-year-old Baron Holmes of Kenwood was stopped at about 12:40 a.m. and appeared to be drunk.
Officers found he showed a .14 percent blood-alcohol level. Because he's not yet 21 years old his legal limit was .05 percent.
Homes and Bagwell were booked into the Sonoma County Jail.
Ten drivers were cited for being unlicensed drivers, three had suspended licenses and one person was wanted on a felony arrest warrant.
The checkpoint was funded by a grant from the California Office of Traffic Safety.
