Lead Opinion
delivered the opinion of the Court.
This Fourth Amendment case focuses upon a highway checkpoint where police stopped motorists to ask them for information about a recent hit-and-run accident. We hold that the police stops were reasonable, hence, constitutional.
The relevant background is as follows: On Saturday, August 23,1997, just after midnight, an unknown motorist traveling eastbound on a highway in Lombard, Illinois, struck and killed a 70-year-old bicyclist. The motorist drove off without identifying himself. About one week later at about the same time of night and at about the same place, local police set up a highway checkpoint designed to obtain more information about the accident from the motoring public.
Police cars with flashing lights bound lanes of the highway. The blockage forced traffic to slow down, leading to lines of up to 15 cars in each lane. As each vehicle drew up to the checkpoint, an officer would stop it for 10 to 15 seconds, ask the occupants whether they had seen anything happen there the previous weekend, and hand each driver a flyer. The flyer said “ALERT . . . FATAL HIT & RUN ACCIDENT” and requested “ASSISTANCE IN IDENTIFYING THE VEHICLE AND DRIVER INVOLVED IN THIS ACCIDENT WHICH KILLED A 70 YEAR OLD BICYCLIST.” App. 9.
Robert Lidster, the respondent, a ward the checkpoint. As he approached the checkpoint, his van swerved, nearly hitting one of the officers. The officer smelled alcohol on Lidster’s breath. He directed Lidster to a side street where another officer administered a sobriety test and then arrested Lidster. Lidster was tried and convicted in Illinois state court of driving under the influence of alcohol.
Lidster challenged the lawfulness of his arrest and conviction on the ground that the government had obtained much of the relevant evidence through use of a checkpoint stop that violated the Fourth Amendment. The triaí court rejected that challenge. But an Illinois appellate court ■reached the opposite conclusion.
Because lower courts have reached different conclusions about this matter, we granted certiorari. See Burns v. Commonwealth,
II
The Illinois Supreme Court basically held that our decision in Edmond governs the outcome of this case. We do not agree. Edmond involved a checkpoint at which police stopped vehicles to look for evidence of drug crimes committed by occupants of those vehicles. After stopping a vehicle at the checkpoint, police would examine (from outside the vehicle) the vehicle’s interior; they would walk a drug-sniffing dog around the exterior; and, if they found sufficient evidence of drug (or other) crimes, they would arrest the vehicle’s occupants.
The checkpoint stop here differs signiAcantly from that in Edmond. The stop’s primary law enforcement purpose was not to determine whether a vehicle’s occupants were committing a crime, but to ask vehicle occupants, as members of the public, for their help in providing information about a crime in all likelihood committed by others. The police expected the information elicited to help them apprehend, not the vehicle’s occupants, but other individuals.
Neither do we believe, Edmond aside, that the Fourth Amendment would have us apply an Edmond-type rule of automatic unconstitutionality to brief, information-seeking highway stops of the kind now before us. For one thing, the fact that such stops normally lack individualized suspicion cannot by itself determine the constitutional outcome. As in Edmond, the stop here at issue involves a motorist. The Fourth Amendment does not treat a motorist’s car as his castle. See, e. g., New York v. Class,
. For another thing, information-seeking highway stops are less likely to provoke anxiety or to prove intrusive. The stops are likely brief. The police are not likely to ask questions designed to elicit self-incriminating information. And citizens will often react positively when police simply ask for their help as “responsible citizen[s]” to “give whatever information they may have to aid in law enforcement.” Miranda v. Arizona,
Further, the law ordinarily permits police to seek the voluntary cooperation of members of the public in the investigation of a crime. “[L]aw enforcement officers do not violate the Fourth Amendment by merely approaching an individual on the street or in another public place, by asking him if he is willing to answer some questions, [or] by putting questions to him if the person is willing to listen.” Florida v. Royer,
The importance of soliciting the public’s assistance is offset to some degree by the need to stop a motorist to obtain that help — a need less likely present where a pedestrian, not a motorist, is involved. The difference is significant in light of our determinations that such an involuntary stop amounts
Finally, we do not believe that an Edmond-type rule is needed to prevent an unreasonable proliferation of police checkpoints. Cf.
These considerations, takén together, convince us that an Edmond-type presumptive rule of unconstitutionality does not apply here. That does not mean the stop is automatically, or even presumptively, constitutional. It simply means that we must judge its reasonableness, hence, its constitutionality, on the basis of the individual circumstances. And as this Court said in Brown v. Texas,

We now consider the reasonableness of the checkpoint stop before us in light of the factors just mentioned, an issue that, in our view, has been fully argued here. See Brief for Petitioner 14-18; Brief for Respondent 17-27. We hold that the stop was constitutional.
The relevant public concern was grave. Police were investigating a crime that had resulted in a human death. No one denies the police’s need to obtain more information at that time. And the stop’s objective was to help find the perpetrator of a specific and known crime, not of unknown crimes of a general sort. Cf. Edmond, supra, at 44.
The stop advanced this grave public concern to a significant degree. The police appropriately tailored their checkpoint stops to fit important criminal investigatory needs. The stops took place about one week after the hit-and-run accident, on the same highway near the location of the accident, and at about the same time of night. And police used the stops to obtain information from drivers, some of whom might well have been in the vicinity of the crime at the time it occurred. See App. 28-29 (describing police belief that motorists routinely leaving work after night shifts at nearby industrial complexes might have seen something relevant).
Most importantly, the stops interfered only minimally with liberty of the sort the Fourth Amendment seeks to protect. Viewed objectively, each stop required only a brief wait in line — a very few minutes at most. Contact with the police lasted only a few seconds. Cf. Martinez-Fuerte, supra, at 547 (upholding stops of three-to-five minutes); Sitz, supra,
For these reasons we conclude that the checkpoint stop was constitutional.
The judgment of the Illinois Supreme Court is
Reversed.
Concurrence Opinion
with whom Justice Souter and Justice Ginsburg join, concurring in part and dissenting in part.
There is a valid and important distinction between seizing a person to determine whether she has committed a crime and seizing a person to ask whether she has any information about an unknown person who committed a crime a week earlier. I therefore join Parts I and II of the Court’s opinion explaining why our decision in Indianapolis v. Edmond,
In contrast to pedestrians, who are free to keep walking when they encounter police officers handing out flyers or seeking information, motorists who confront a roadblock are required to stop, and to remain stopped for as long as the officers choose to detain them. Such a seizure may seem
On the other side of the equation, the likelihood that questioning a random sample of drivers will yield useful information about a hit-and-run accident that occurred a week earlier is speculative at best. To be sure, the sample in this case was not entirely random: The record reveals that the police knew that the victim had finished work at the Post Office shortly before the fatal accident, and hoped that other employees of the Post Office or the nearby industrial park might work on similar schedules and, thus, have been driving the same route at the same time the previous week. That is a plausible theory, but there is no evidence in the record that the police did anything to confirm that the nearby businesses in fact had shift changes at or near midnight on Saturdays, or that they had reason to believe that a roadblock would be more effective than, say, placing flyers on the employees’ cars.
In short, the outcome of the multifactor test prescribed in Brown v. Texas,
