Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 93 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“[T]he conduct of the roadblock itself can be such that it requires only a momentary stop to allow the police to make a brief but trained observation of a vehicle's driver, without entailing any physical search of the vehicle or its occupants. To avoid unnecessary surprise to motorists, the existence of a roadblock can be so conducted as to be ascertainable from a reasonable distance or otherwise made knowable in advance. The possibility of arbitrary roadblocks can be significantly curtailed by the institution of certain safeguards. First the very decision to hold a drunk-driver roadblock, as well as the decision as to its time and place, should be matters reserved for prior administrative approval, thus removing the determination of those matters from the discretion of police officers in the field. In this connection it is essential that the route selected for the roadblock be one which, based on local experience, is likely to be travelled by intoxicated drivers. The time of the roadblock should be governed by the same consideration. Additionally, the question of which vehicles to stop at the roadblock should not be left to the unfettered discretion of police officers at the scene, but instead should be in accordance with objective standards prefixed by administrative decision.”
