OPINION OF THE COURT
A roadblock established pursuant to a written directive of the County Sheriff for the purpose of detecting and deterring driving while intoxicated or while impaired, and as to which operating personnel are prohibited from administering sobriety tests unless they observe listed criteria, indicative of intoxication, which give substantial cause to believe that the operator is intoxicated, is constitutionally permissible, notwithstanding that the location of the roadblock is moved several times during the three- to four-hour period of operation, and notwithstanding that legislative initiatives have also played a part in reducing the incidence of driving while intoxicated in recent years. Defendant having pleaded guilty to driving while impaired after denial of his motion to suppress the evidence obtained at the roadblock, the order of the County Court, Genesee County, affirming his conviction, should, therefore, be affirmed.
I
At about 2:00 a.m. on Saturday, September 25, 1982, defendant, while driving on Route 5 in the Town of LeRoy, came up to a roadblock established pursuant to a directive of the Sheriff of Genesee County. He was directed to pull to
The roadblock had been established pursuant to a March 5, 1982 memorandum of the County Sheriff which called attention to the deaths, injuries and losses occasioned by intoxicated drivers and the need “to employ every lawful means to deter and apprehend the drunken driver.” It quoted from the October, 1981 Report of the Governor’s Alcohol and Highway Safety Task Force the value of “systematic traffic checkpoints at known DWI and high accident locations during peak hours”, and the advisability that, “Such checks at specific sites * * * be of short duration, with an ability to move quickly to new sites to insure that the drinking driver will not be able to forecast checkpoint locations”, and noted that the “greatest risk is on weekend late evening/early morning hours, when one in every ten vehicles or less contains an intoxicated driver.” In succeeding detailed paragraphs it established procedures for site selection, lighting and signs; avoidance of discrimination by stopping all vehicles, or every second, third or fourth vehicle; location of screening areas off the highway to which vehicles would be directed; the nature of the inquiries to be made, with specific direction that unless the operator’s appearance and demeanor gave cause to believe him or her intoxicated sobriety tests not be given. It listed the factors to be considered and stated that neither the odor of alcohol alone nor any one of the listed factors would suffice as a basis for sobriety tests. It also directed that checkpoint sites be prescreened and that from two to four locations be used during a four-hour period.
Defendant moved to suppress the evidence obtained at the roadblock. After a hearing the Town Justice denied the motion, finding that it had been operated in a uniform, nonarbitrary and nondiscriminatory manner. The County Court affirmed, finding the State’s interest in curbing drunken drivers great and the operation of the roadblock sufficient to allay feelings of fright or annoyance and to circumscribe sufficiently the discretion of the personnel engaged in the operation. On appeal to this court defendant argues that deterrence is an improper purpose, that a temporary roadblock is constitutionally impermissible, and that it has not been shown that less intrusive means of enforcement would not be effective. We affirm.
II
There is, of course, no question that a roadblock or checkpoint stop is a seizure within the meaning of the Fourth Amendment (People u John BB.,
The permissibility of a particular practice is a function of its “reasonableness,” which is determined by balancing its intrusion on the Fourth Amendment interests of the individual involved against its promotion of legitimate governmental interests (People v John BB., supra, at p 487; United States v Villamonte-Marquez,
The importance of the governmental interest here involved is beyond question. “The carnage caused by drunk drivers is well documented and needs no detailed recitation here” (South Dakota v Neville,
Moreover, in light of the specific procedures devised and promulgated to law enforcement personnel by the head of their department, the Sheriff, and the way in which the particular roadblock was being operated when defendant was stopped, the courts below could properly conclude that it did not intrude to an impermissible degree upon the privacy of motorists approaching the checkpoint, that it was being maintained in accordance with a uniform procedure which afforded little discretion to operating personnel, and that adequate precautions as to safety, lighting and fair warning of the existence of the checkpoint were in operation (People v Peil,
Nor is the plan invalid because of its deterrent purpose, the shifting of checkpoints after short periods of time, or the question raised by defendant concerning its efficiency.
The value of roadblocks in decreasing drunk driving is attested by both the United States Department of Transportation and the Governor’s Alcohol and Highway Safety Task Force. A 1983 paper on Safety Checkpoints For DWI Enforcement issued by the Department of Transportation’s National Highway Traffic Safety Administration’s Office of Alcohol Countermeasures emphasizes the importance of informing the public about DWI checkpoint operations as
Nor is constitutionality affected by the shifting and temporary nature of the checkpoints. The fact that the Supreme Court has approved permanent roadblocks but disapproved roving patrol stops is not determinative. What is critical is the intrusiveness of the checkpoint in relation to the governmental purpose involved. The subjective effect upon a vehicle driver approaching a roadblock is unrelated to whether it is permanent or was established but a few minutes before the driver approached it; in either instance his or her observation of it will be measured in minutes if not seconds. The likelihood of there being the kind of fright or annoyance that invalidates a random stop made by a roving patrol is obviated in the case of a temporary checkpoint by the visible signs of authority which the checkpoint entails — signs announcing the purpose, lighting, and identifiable police vehicles and the observable fact that there is a uniform system for stopping cars (United States v Hernandez, 739 F2d 484; Little v State, supra). The only subjective difference between temporary and permanent checkpoints is that because its location is known in advance the latter can be avoided
Nor, finally, is there sufficient question about the productivity of DWI checkpoints to require invalidation of the procedure. The contrary argument is based on the effectiveness of the procedure as a means of apprehension and ignores entirely its deterrent effect.
For the foregoing reasons, the order of the County Court, Genesee County, should be affirmed.
Chief Judge Cooke and Judges Jasen, Jones, Wachtler, Simons and Kaye concur.
Order affirmed.
Notes
. The guidelines called for a distance of 500 to 1,000 yards but the courts below found the change to have been approved by the Sheriff.
. Defendant disputes that all vehicles were stopped, but there being affirmed findings to that effect which have support in the record, the issue is beyond our review.
. The brief of amicus New York Civil Liberties Union states on the basis of a September, 1983 Report of the Driving While Intoxicated Unit of the New York City Police Department that less than Vio of 1% of the motorists stopped were arrested for driving under the influence of alcohol.
. The Civil Liberties Union brief points to the sentence at page 6 of the Report of the Assembly Subcommittee on Drunk Driving, stating that “highly publicized local enforcement efforts, such as random roadblocks, have prompted civil libertarians to warn of Orwellian intrusions into individual privacy,” and notes that such roadblocks were not a part of the legislative package. The Legislature is, of course, free to enact procedures authorizing such roadblocks and establishing procedures to be followed (e.g., Montana Code Ann, § 46-5-503; South Dakota Codified Laws Ann, § 32-33-12; Wyoming Stats Ann, § 7-17-103; and see State v Deskins, 234 Kan 529, at p 543, suggesting adoption of minimum uniform standards for roadblocks by the Legislature) or to proscribe the use of DWI roadblocks, if it sees fit to do so (cf. Ifft, 71 Georgetown U 1457, at p 1459, n 5). Its failure to do either is, however, of no significance in the determination of the constitutional validity of the procedure under consideration.
