Pleasanton police made one arrest last Friday night of a driver under the influence at a checkpoint on Stoneridge Drive and Johnson that kicked off the Labor Day weekend, said Traffic Sgt. Robert Leong.
During the five-hour checkpoint, 1,068 vehicles passed through and 947 were stopped.
"Because of the backup, we have to let a certain amount through," said Leong.
"Thirty-three drivers had their license status checked," he reported. "Either they didn't have it on them or didn't have a license or they were suspended. Out of those, we issued 10 citations for drivers being unlicensed or suspended."
They also cited three teen drivers with provisional licenses for violations.
Police conducted six field sobriety tests at the checkpoint and made one arrest.
This checkpoint was the first this year although there were several in 2009, said Leong. Funding for the checkpoint was provided by a grant from the California Office of Traffic Safety through the National Highway Traffic Safety Administration.
