A drunken driver checkpoint Friday night in Santa Rosa netted only one suspected intoxicated driver but it also resulted in 54 drivers cited for license violations, reported police.
The checkpoint was held on Morgan Street, south of Fifth Street near downtown Santa Rosa.
It was open from 6 p.m. to midnight.
In that time 1027 vehicles passed through the checkpoint and officers screened 889 drivers, said Petaluma traffic Officer Walt Spiller.
Of those, officers gave a harder look at 92 drivers.
One was found to be suspected of drunken driving.
Officers found 47 drivers were unlicensed and seven drivers had a suspended license, Spiller said.
They towed nine vehicles.
The checkpoint was part of the long Fourth of July holiday weekend effort to catch drunken drivers.
It was operated by officers from several local law enforcement agencies.
The checkpoint was paid for by a grant from the California Office of Traffic Safety.
