The following is an image taken from the Oklahoma County Sheriff's Office twitter feed this morning:

Additionally, the state has also provided a map to all active "checkpoints". Find it by following this link: http://enduiok.com/
Of course, there are viable challenges to these stops. The Oklahoma Court of Criminal Appeals allows these checkpoints, properly called 4th amendment seizures, under narrow circumstances. The law enforcement agency may or may not be in compliance. Be smart when approaching these, you have Rights.
Call me for representation if needed.
