What exactly is a DUI type checkpoint? Do you have roadblocks where officers stop every car and simply ask for license and registration without cause?
That's it in one.
"An additional source of guidelines can be found in an earlier decision by the California Supreme Court (Ingersoll v. Palmer (43 Cal.3d 1321 (1987)) wherein the Court set forth what it felt to be necessary standards in planning and administering a sobriety checkpoint:
A checkpoint in the United States
* Decision making must be at a supervisory level, rather than by officers in the field.
* A neutral formula must be used to select vehicles to be stopped, such as every vehicle or every third vehicle, rather than leaving it up the officer in the field.
* Primary consideration must be given to public and officer safety.
* The site should be selected by policy-making officials, based upon areas having a high incidence of drunk driving.
* Limitations on when the checkpoint is to be conducted and for how long, bearing in mind both effectiveness and intrusiveness.
* Warning lights and signs should be clearly visible.
* Length of detention of motorists should be minimized.
* Advance publicity is necessary to reduce the intrusiveness of the checkpoint and increase its deterrent effect."

"Even though the US Supreme Court said sobriety checkpoints are constitutional, ten states still do not allow them: Idaho, Iowa, Michigan, Minnesota, Oregon, Rhode Island, Texas, Washington, Wisconsin, and Wyoming."
