[447] Chief Justice Rehnquist
delivered the opinion of the Court.
This case poses the question whether a State’s use of highway sobriety checkpoints violates the Fourth and Fourteenth Amendments to the United States Constitution. We hold that it does not and therefore reverse the contrary holding of the Court of Appeals of Michigan.
Petitioners, the Michigan Department of State Police and its director, established a sobriety checkpoint pilot program in early 1986. The director appointed a Sobriety Checkpoint Advisory Committee comprising representatives of the State Police force, local police forces, state prosecutors, and the University of Michigan Transportation Research Institute. Pursuant to its charge, the advisory committee created guidelines setting forth procedures governing checkpoint operations, site selection, and publicity.
Under the guidelines, checkpoints would be set up at selected sites along state roads. All vehicles passing through a checkpoint would be stopped and their drivers briefly examined for signs of intoxication. In cases where a checkpoint officer detected signs of intoxication, the motorist would be directed to a location out of the traffic flow where an officer would check the motorist’s driver’s license and car registration and, if warranted, conduct further sobriety tests. Should the field tests and the officer’s observations suggest that the driver was intoxicated, an arrest would be made. All other drivers would be permitted to resume their journey immediately.
[448] The first—and to date the only—sobriety checkpoint operated under the program was conducted in Saginaw County with the assistance of the Saginaw County Sheriff’s Department. During the 75-minute duration of the checkpoint’s operation, 126 vehicles passed through the checkpoint. The average delay for each vehicle was approximately 25 seconds. Two drivers were detained for field sobriety testing, and one of the two was arrested for driving under the influence of alcohol. A third driver who drove through without stopping was pulled over by an officer in an observation vehicle and arrested for driving under the influence.
On the day before the operation of the Saginaw County checkpoint, respondents filed a complaint in the Circuit Court of Wayne County seeking declaratory and injunctive relief from potential subjection to the checkpoints. Each of the respondents “is a licensed driver in the State of Michigan . . . who regularly travels throughout the State in his automobile.” See Complaint, App. 3a-4a. During pretrial proceedings, petitioners agreed to delay further implementation of the checkpoint program pending the outcome of this litigation.
After the trial, at which the court heard extensive testimony concerning, inter alia, the “effectiveness” of highway sobriety checkpoint programs, the court ruled that the Michigan program violated the Fourth Amendment and Art. 1, § 11, of the Michigan Constitution. App. to Pet. for Cert. 132a. On appeal, the Michigan Court of Appeals affirmed the holding that the program violated the Fourth Amendment and, for that reason, did not consider whether the program violated the Michigan Constitution. 170 Mich. App. 433, 445, 429 N. W. 2d 180, 185 (1988). After the Michigan Supreme Court denied petitioners’ application for leave to appeal, we granted certiorari. 493 U. S. 806 (1989).
To decide this case the trial court performed a balancing test derived from our opinion in Brown v. Texas, 443 U. S. 47 (1979). As described by the Court of Appeals, the test in[449] volved “balancing the state’s interest in preventing accidents caused by drunk drivers, the effectiveness of sobriety checkpoints in achieving that goal, and the level of intrusion on an individual’s privacy caused by the checkpoints.” 170 Mich. App., at 439, 429 N. W. 2d, at 182 (citing Brown, supra, at 50-51). The Court of Appeals agreed that “the Brown three-prong balancing test was the correct test to be used to determine the constitutionality of the sobriety checkpoint plan.” 170 Mich. App., at 439, 429 N. W. 2d, at 182.
As characterized by the Court of Appeals, the trial court’s findings with respect to the balancing factors were that the State has “a grave and legitimate” interest in curbing drunken driving; that sobriety checkpoint programs are generally “ineffective” and, therefore, do not significantly further that interest; and that the checkpoints’ “subjective intrusion” on individual liberties is substantial. Id., at 439, 440, 429 N. W. 2d, at 183, 184. According to the court, the record disclosed no basis for disturbing the trial court’s findings, which were made within the context of an analytical framework prescribed by this Court for determining the constitutionality of seizures less intrusive than traditional arrests. Id., at 445, 429 N. W. 2d, at 185.
In this Court respondents seek to defend the judgment in their favor by insisting that the balancing test derived from Brown v. Texas, supra, was not the proper method of analysis. Respondents maintain that the analysis must proceed from a basis of probable cause or reasonable suspicion, and rely for support on language from our decision last Term in Treasury Employees v. Von Raab, 489 U. S. 656 (1989). We said in Von Raab:
“[W]here a Fourth Amendment intrusion serves special governmental needs, beyond the normal need for law enforcement, it is necessary to balance the individual’s privacy expectations against the Government’s interests to determine whether it is impractical to require a warrant [450] or some level of individualized suspicion in the particular context.” Id., at 665-666.
Respondents argue that there must be a showing of some special governmental need “beyond the normal need” for criminal law enforcement before a balancing analysis is appropriate, and that petitioners have demonstrated no such special need.
But it is perfectly plain from a reading of Von Raab, which cited and discussed with approval our earlier decision in United States v. Martinez-Fuerte, 428 U. S. 543 (1976), that it was in no way designed to repudiate our prior cases dealing with police stops of motorists on public highways. Martinez-Fuerte, supra, which utilized a balancing analysis in approving highway checkpoints for detecting illegal aliens, and Brown v. Texas, supra, are the relevant authorities here.
Petitioners concede, correctly in our view, that a Fourth Amendment “seizure” occurs when a vehicle is stopped at a checkpoint. Tr. of Oral Arg. 11; see Martinez-Fuerte, supra, at 556 (“It is agreed that checkpoint stops are ‘seizures’ within the meaning of the Fourth Amendment”); Brower v. County of Inyo, 489 U. S. 593, 597 (1989) (Fourth Amendment seizure occurs “when there is a governmental termination of freedom of movement through means intentionally applied” (emphasis in original)). The question thus becomes whether such seizures are “reasonable” under the Fourth Amendment.

Respondents maintain that the analysis must proceed from a basis of probable cause or reasonable suspicion, and rely for support on language from our decision last Term in Treasury Employees v.

Martinez-Fuerte, supra, which utilized a balancing analysis in approving highway checkpoints for detecting illegal aliens, and Brown v. Texas, supra, are the relevant authorities here.
Petitioners concede, correctly in our view, that a Fourth Amendment “seizure” occurs when a vehicle is stopped at a checkpoint. Tr. of Oral Arg. 11; see Martinez-Fuerte, supra, at 556 (“It is agreed that checkpoint stops are ‘seizures’ within the meaning of the Fourth Amendment”); Brower v. County of Inyo, 489 U.

The question thus becomes whether such seizures are “reasonable” under the Fourth Amendment.
It is important to recognize what our inquiry is not about. No allegations are before us of unreasonable treatment of any person after an actual detention at a particular checkpoint. See Martinez-Fuerte, 428 U. S., at 559 (“[C]laim that a particular exercise of discretion in locating or operating a checkpoint is unreasonable is subject to post-stop judicial review”). As pursued in the lower courts, the instant action challenges only the use of sobriety checkpoints generally. We address only the initial stop of each motorist passing through a checkpoint and the associated preliminary questioning and ob[451] servation by checkpoint officers. Detention of particular motorists for more extensive field sobriety testing may require satisfaction of an individualized suspicion standard. Id., at 567.
No one can seriously dispute the magnitude of the drunken driving problem or the States’ interest in eradicating it. Media reports of alcohol-related death and mutilation on the Nation’s roads are legion. The anecdotal is confirmed by the statistical. “Drunk drivers cause an annual death toll of over 25,000 [
