Defendants appeal the trial court's denial of their motions to suppress evidence.
We affirm as to both defendants. The purpose of the roadblock was to detect and apprehend drunk drivers. A supervisor in the Las Cruces police department advised the field officers conducting the roadblock of the operation and briefed them on the procedures to be utilized. The field officers were provided with a written outline of what to say to motorists who were stopped at the roadblock. Officer Childress, along with two or three other officers, manned the roadblock.
