State by State DUI Checkpoint Laws

In the state of Oregon, DUI checkpoints have been banned. Anyone that moves to the state from California or Nevada may not realize that sobriety checkpoints are not authorized (see State v. Boyanovsky, 743 P.2d 711 (Or. 1987)). Studies have shown that DUI checkpoints reduce alcohol related crashes by as much as 9%. That said, for Oregon law enforcement officials to start setting up DUI checkpoints there will have to be legislation that is voted on by the residents of the state.
