Several city and state police agencies gathered together to patrol west Valley roadways in a targeted Friday night enforcement effort.
The Arizona Department of Public Safety say in all, 34 drivers were arrested for DUI during the Friday night task force.
DPS says the West Valley DUI Task Force involved more than 66 officers, all hoping to make the holidays safer as people make their way to holiday parties and other events.
Police from Phoenix, Goodyear, Peoria, Glendale, Buckeye, Surprise, Avondale, Wickenburg, El Mirage and ASU participated, along with Maricopa County Sheriff's Office and DPS.
"Know that if you drive impaired, the combined effort of more than a dozen police agencies will be looking for you," Captain Tim Mason with DPS said in a statement.
"I commend the dedication of all law enforcement officers statewide who are risking their own lives in getting impaired drivers off our highways and roads," Alberto Gutier with the Governor's Office of Highway Safety said in a statement.
Just Saturday morning a wrong-way driver was arrested on the Loop 101 near 35th Avenue, by one of the task force officers and suspected of DUI.
