According to law enforcement press releases, the Oakland and Vallejo Police Departments will both conduct driving under the influence (DUI) checkpoints this weekend.  Oakland will have their checkpoint at an "undisclosed" location within the city.  It will be up on Friday, June 29, 2012, and last from 6:00pm until 2:00am.  Vallejo PD says there DUI checkpoint will be on Satuday evening in Benicia. 

It is also prudent to remind you that San Francisco and Santa Rosa will also host DUI Checkpoints this weekend.  I wrote about those two cities in earlier posts this week.
