PER CURIAM
In this case of driving under the influence of intoxicants, defendant appeals the trial court's denial of his motion to suppress evidence arising out of a traffic roadblock at which he was stopped and arrested. We cannot perceive a principled way in which this case may be distinguished from State v. Tourtillott, 289 Or. 845, 618 P.2d 423 (1980). It is therefore affirmed.
Affirmed.
