The Labor Day weekend search for drunken drivers included two checkpoints in Santa Rosa.
The checkpoints resulted in the arrest of one driver on suspicion of being under the influence, 11 drivers for not being licensed and two, including the drunken-driving suspect, for driving with suspended licenses, according to Santa Rosa Police Sgt. Rich Celli.
Officers stopped cars on Santa Rosa Avenue at Sonoma Avenue and on College Avenue at Morgan Street.
One vehicle was impounded.
Darren Waltz, 39, was stopped in the checkpoint on Santa Rosa Avenue. His blood alcohol level was listed at .16, Celli said.
Officers stopped and spoke to 1,098 drivers at the two checkpoints. Of those drivers, 60 were checked for a valid license and nine were given sobriety tests.
