A DUI checkpoint in Rohnert Park Saturday night netted no impaired drivers but nine were given citations for license violations, according to police.

The checkpoint, held on the Rohnert Park Expressway near State Farm Drive, ran from 8 p.m. Saturday to 1 a.m. Sunday.

Officers screened 1,180 drivers and gave a second look at 30 of them, checking for possible DUI and license status. No one was found to be under the influence of alcohol or drugs but nine people were behind the wheel despite not having a license to drive, police said.

To avoid having their vehicles towed, the drivers were allowed to contact someone with a license to come get them and their car.

The checkpoint was funded by a California Office of Traffic Safety grant.
