Nine drivers were cited for being unlicensed or driving with a suspended license at a checkpoint in Pomona, authorities said Saturday.
The checkpoint was set up at the intersection of Garey and Monterey avenues from 9 p.m. Friday to 1 a.m. Saturday, the Pomona Police Department said.
A total of 556 vehicles were screened during the checkpoint.
Last year Pomona police investigated 100 DUI crashes that resulted in two deaths, according to the department.
Funding for the checkpoint was provided by a grant from the California Office of Traffic Safety through the National Highway Traffic Safety Administration.
