  Justice Scalia
  delivered the opinion of the Court.
  This case presents the question whether police officers violate the Fourth Amendment when they search a passenger’s personal belongings inside an automobile that they have probable cause to believe contains contraband.
  I
  In the early morning hours of July 23, 1995, a Wyoming Highway Patrol officer stopped an automobile for speeding and driving with a faulty brake light. There were three passengers in the front seat of the car: David Young (the driver), his girlfriend, and respondent. While questioning Young, the officer noticed a hypodermic syringe in Young’s shirt pocket. He left the occupants under the supervision of two backup officers as he went to get gloves from his patrol ear. Upon his return, he instructed Young to step out of the car and place the syringe on the hood. The officer then asked Young why he had a syringe; with refreshing candor, Young replied that he used it to take drugs.
  At this point, the backup officers ordered the two passengers out of the ear and asked them for identification. Respondent falsely identified herself as “Sandra James” and stated that she did not have any identification. Meanwhile, in light of Young’s admission, the officer searched the passenger compartment of the car for contraband. On the back seat, he found a purse, which respondent claimed as hers. He removed from the purse a wallet containing respondent’s driver’s license, identifying her properly as Sandra K. Houghton. When the officer asked her why she had lied about her name, she replied: “In case things went bad.”
  Continuing purse, brown pouch and a black wallet-type container. Respondent denied that the former was hers, and claimed ignorance of how it came to be there; it was found to contain drug paraphernalia and a syringe with 60 ccs of methamphetamine. Respondent admitted ownership of the black container, which was also found to contain drug paraphernalia, and a syringe (which respondent acknowledged was hers) with 10 ccs of methamphetamine — an amount insufficient to support the felony conviction at issue in this ease. The officer also found fresh needle-track marks on respondent’s arms. He placed her under arrest.
  The State of Wyoming possession of methamphetamine in a liquid amount greater than three-tenths of a gram. See Wyo. Stat. Ann. §35-7-1031(c)(iii) (Supp. 1996). After a hearing, the trial court denied her motion to suppress all evidence obtained from the purse as the fruit of a violation of the Fourth and Fourteenth Amendments. The court held that the officer had probable cause to search the car for contraband, and, by extension, any containers therein that could hold such contraband. A jury convicted respondent as charged.
  The Wyoming Supreme Court, by divided vote, reversed the conviction and announced the following rule:
  “Generally, once probable cause is established to search a vehicle, an officer is entitled to search all containers therein which may contain the object of the search. However, if the officer knows or should know that a container is the personal effect of a passenger who is not suspected of criminal activity, then the container is outside the scope of the search unless someone had the opportunity to conceal the contraband within the personal effect to avoid detection.” 956 P. 2d 368, 872 (1998).
  The court held that the search of respondent’s purse violated the Fourth and Fourteenth Amendments because the officer “knew or should have known that the purse did not belong to the driver, but to one of the passengers,” and because “there was no probable cause to search the passengers’ personal effects and no reason to believe that contraband had been placed within the purse.” Ibid. We granted certio-rari, 524 U. S. 983 (1998).
  II
  The Fourth Amendment protects “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” In determining whether a particular governmental action, violates this provision, we inquire first whether the action was regarded as an unlawful search or seizure under the common law when the Amendment was framed. See Wilson v. Arkansas, 514 U. S. 927, 931 (1995); California v. Hodari D., 499 U. S. 621, 624 (1991). Where that inquiry yields no answer, we must evaluate the search or seizure under traditional standards of reasonableness by assessing, on the one hand, the degree to which it intrudes upon an individual’s privacy and, on the other, the degree to which it is needed for the promotion of legitimate governmental interests. See, e. g., Vernonia School Dist. 47J v. Acton, 515 U. S. 646, 652-653 (1995).
  It is uncontested in the ease had probable cause to believe there were illegal drugs in the car. Carroll v. United States, 267 U. S. 132 (1925), similarly involved the warrantless search of a car that law enforcement officials had probable cause to believe contained contraband — in that case, bootleg liquor. The Court concluded that the Framers would have regarded such a search as reasonable in light of legislation enacted by Congress from 1789 through 1799 — as well as subsequent legislation from the founding era and beyond — that empowered customs officials to search any ship or vessel without a warrant if they had probable cause to believe that it contained goods subject to a duty. Id., at 150-153. See also United States v. Ross, 456 U. S. 798, 806 (1982); Boyd v. United States, 116 U. S. 616, 623-624 (1886). Thus, the Court held that "contraband goods concealed and illegally transported in an automobile or other vehicle may be searched for without a warrant” where probable cause exists. Carroll, supra, at 153.
  We have furthermore that the Framers would have regarded as reasonable (if there was probable cause) the warrantless search of containers within an automobile. In Ross, supra, we upheld as reasonable the warrantless search of a paper bag and leather pouch found in the trunk of the defendant’s ear by officers who had probable cause to believe that the trunk contained drugs. Justice Stevens, writing for the Court, observed:
  "It is noteworthy that the early legislation on which the Court relied in Carroll concerned the enforcement of laws imposing duties on imported merchandise. . . . Presumably such merchandise was shipped then in containers of various kinds, just as it is today. Since Congress had authorized warrantless searches of vessels and beasts for imported merchandise, it is inconceivable that it intended a customs officer to obtain a warrant for every package discovered during the search; certainly Congress intended customs officers to open shipping containers when necessary and not merely to examine the exterior of cartons or boxes in which smuggled goods might be concealed. During virtually the entire history of our country — whether contraband was transported in a horse-drawn carriage, a 1921 roadster, or a modern automobile — it has been assumed that a lawful search of a vehicle would include a search of any container that might conceal the object of the search.” Id., at 820, n. 26.
  Ross summarized its holding as follows: "If probable cause justifies the search of a lawfully stopped vehicle, it justifies the search of every part of the vehicle and its contents that may conceal the object of the search.” Id., at 825 (emphasis added). And our later cases describing Ross have characterized it as applying broadly to all containers within a car, without qualification as to ownership. See, e. g., California v. Acevedo, 500 U. S. 565, 572 (1991) (“[TJhis Court in Ross took the critical step of saying that closed containers in ears could be searched without a warrant because of their presence within the automobile”); United States v. Johns, 469 U. S. 478, 479-480 (1985) (Ross “held that if police officers have probable cause to search a lawfully stopped vehicle, they may conduct a warrantless search of any containers found inside that may conceal the object of the search”).
  no passenger in Ross, and it was not claimed that the package in the trunk belonged to anyone other than the driver. Even so, if the rule of law that Ross announced were limited to contents belonging to the driver, or contents other than those belonging to passengers, one would have expected that substantial limitation to be expressed. And, more importantly, one would have expected that limitation to be apparent in the historical evidence that formed the basis for Ross’,s holding. In fact, however, nothing in the statutes Ross relied upon, or in the practice under those statutes, would except from authorized warrantless search packages belonging to passengers on the suspect ship, horse-drawn carriage, or automobile.
  Finally, we must derlying the rule announced in Ross is fiilly consistent — as respondent’s proposal is not — with the balance of our Fourth Amendment jurisprudence. Ross concluded from the historical evidence that the permissible scope of a warrantless car search “is defined by the object of the search and the places in which there is probable cause to believe that it may be found.” 456 U. S., at 824. The same principle is reflected in an earlier case involving the constitutionality of a search warrant directed at premises belonging to one who is not suspected of any crime: “The critical element in a reasonable search is not that the owner of the property is suspected of crime but that there is reasonable cause to believe that the specific ‘things’ to be searched for and seized are located on the property to which entry is sought.” Zurcher v. Stanford Daily, 486 U. S. 547, 556 (1978). This statement was illustrated by citation and description of Carroll, 267 U. S., at 158-159, 167. 436 U. S., at 556-557.
  In sum, neither Ross nor relied upon admits of a distinction among packages or containers based on ownership. When there is probable cause to search for contraband in a ear, it is reasonable for police officers — like customs officials in the founding era — to examine packages and containers without a showing of individualized probable cause for each one. A passenger’s personal belongings, just like the driver’s belongings or containers attached to the car like a glove compartment, are “in” the car, and the officer has probable cause to search for contraband in the car.
  Even if the historical evidence, as described by Ross, were thought to be equivocal, we would find that the balancing of the relative interests weighs decidedly in favor of allowing searches of a passenger’s belongings. Passengers, no less than drivers, possess a reduced expectation of privacy with regard to the property that they transport in cars, which “trave[l] public thoroughfares,” Cardwell v. Lewis, 417 U. S. 583, 590 (1974), “seldom serv[e] as ... the repository of personal effects,” ibid., are subjected to police stop and examination to enforce “pervasive” governmental controls “[a]s an everyday occurrence,” South Dakota v. Opperman, 428 U. S. 364, 368 (1976), and, finally, are exposed to traffic accidents that may render all their contents open to public scrutiny.
  degree of intrusiveness upon personal privacy and indeed even personal dignity — the two cases the Wyoming Supreme Court found dispositive differ substantially from the package search at issue here. United States v. Di Re, 332 U. S. 581 (1948), held that probable cause to search a ear did not justify a body search of a passenger. And Ybarra v. Illinois, 444 U. S. 85 (1979), held that a search warrant for a tavern and its bartender did not permit body searches of all the bar’s patrons. These eases turned on the unique, significantly heightened protection afforded against searches of one’s person. “Even a limited search of the outer clothing . . . constitutes a severe, though brief, intrusion upon cherished personal security, and it must surely be an annoying, frightening, and perhaps humiliating experience.” Terry v. Ohio, 392 U. S. 1, 24-25 (1968). Such traumatic consequences are not to be expected when the police examine an item of personal property found in a car.
  Whereas the passenger’s privacy expectations are, as we have described, considerably diminished, the governmental interests at stake are substantial. Effective law enforcement would be appreciably impaired without the ability to search a passenger’s personal belongings when there is reason to believe contraband or evidence of criminal wrongdoing is hidden in the ear. As in all car-search eases, the “ready mobility” of an automobile creates a risk that the evidence or contraband will be permanently lost while a warrant is obtained. California v. Carney, 471 U. S. 386, 390 (1985). In addition, a car passenger — unlike the unwitting tavern patron in Ybarra — will often be engaged in a common enterprise with the driver, and have the same interest in concealing the fruits or the evidence of their wrongdoing. Cf. Maryland v. Wilson, 519 U. S. 408, 413-414 (1997). A criminal might be able to hide contraband in a passenger’s belongings as readily as in other containers in the ear, see, e. g., Rawlings v. Kentucky, 448 U. S. 98, 102 (1980) — perhaps even surreptitiously, without the passenger’s knowledge or permission. (This last possibility provided the basis for respondent’s defense at trial; she testified that most of the seized contraband must have been placed in her purse by her traveling companions at one or another of various times, including the time she was “half asleep” in the car.)
  a search will not always be present, but the balancing of interests must be conducted with an eye to the generality of cases. To require that the investigating officer have positive reason to believe that the passenger and driver were engaged in a common enterprise, or positive reason to believe that the driver had time and occasion to conceal the item in the passenger’s belongings, surreptitiously or with friendly permission, is to impose requirements so seldom met that a “passenger’s property” rule would dramatically reduce the ability to find and seize contraband and evidence of crime. Of course these requirements would not attach (under the Wyoming Supreme Court’s rule) until the police officer knows or has reason to know that the container belongs to a passenger. But once a “passenger’s property” exception to car searches became widely known, one would expect passenger-confederates to claim everything as their own. And one would anticipate a bog of litigation — in the form of both civil lawsuits and motions to suppress in criminal trials — involving such questions as whether the officer should have believed a passenger’s claim of ownership, whether he should have inferred ownership from various objective factors, whether he had probable cause to believe that the passenger was a confederate, or to believe that the driver might have introduced the contraband into the package with or without the passenger’s knowledge. When balancing the competing interests, our determinations of “reasonableness” under the Fourth Amendment must take account of these practical realities. We think they militate in favor of the needs of law enforcement, and against a personal-privacy interest that is ordinarily weak.
  Finally, if we were cal practice that Ross accurately described and summarized, it is perplexing why that exception should protect only property belonging to a passenger, rather than (what seems much more logical) property belonging to anyone other than the driver. Surely Houghton’s privacy would have been invaded to the same degree whether she was present or absent when her purse was searched. And surely her presence in the car with the driver provided more, rather than less, reason to believe that the two were in league. It may ordinarily be easier to identify the property as belonging to someone other than the driver when the purported owner is present to identify it — but in the many cases (like Ross itself) where the ear is seized, that identification may occur later, at the station house; and even at the site of the stop one can readily imagine a package clearly marked with the owner’s name and phone number, by which the officer can confirm the driver’s denial of ownership. The sensible rule (and the one supported by history and case law) is that such a package may be searched, whether or not its owner is present as a passenger or otherwise, because it may contain the contraband that the officer has reason to believe is in the car.
  •fí ^
  We hold that police officers with probable cause to search a car may inspect passengers’ belongings found in the ear that are capable of concealing the object of the search. The judgment of the Wyoming Supreme Court is reversed.
  It is so ordered.
  The dissent begins its analysis, post, at 309-310 (opinion of Stevens, J.), with an assertion that this ease is governed by our decision in United States v. Di Re, 332 U. S. 581 (1948), which held, as the dissent describes it, that the automobile exception to the warrant requirement did not justify “searches of the passenger’s pockets and the space between his shirt and underwear,” post, at 309. It attributes that holding to “the settled distinction between drivers and passengers,” rather than to a distinction between search of the person and search of property, which the dissent claims is “newly minted” by today’s opinion — a “new rule that is based on a distinction between property contained in clothing worn by a passenger and property contained in a passenger’s briefcase or purse.” Post, at 309, 309-310.
  Jackson’s opinion in Di Re, which makes it very clear that it is precisely this distinction between seareh of the person and search of property that the ease relied upon:
  “The Government says warrant for a residence only, it could search all persons found in it. But an occupant of a house could be used to conceal this contraband on his person quite as readily as can an occupant of a car.” 332 U. S., at 587 (quoted post, at 312).
  Does the dissent really believe that Justice was house search could not inspect property belonging to persons found in the house — say a large standing safe or violin case belonging to the owner’s visiting godfather? Of course that'is not what Justice Jackson meant at all. He was referring precisely to that “distinction between property contained in clothing worn by a passenger and property contained in a passenger’s briefcase or purse” that the dissent disparages, post, at 309. This distinction between searches of the person and searches of property is assuredly not “newly minted,” see post, at 310. And if the dissent thinks “pockets” and “clothing” do not count as part of the person, it must believe that the only searches of the person are strip searches.
  The dissent is “confident in a police officer's ability to apply a rule requiring a warrant or individualized probable cause to search belongings that are ... obviously owned by and in the custody of a passenger,” pout, at 311. If this is the dissent’s strange criterion for warrant protection (“obviously owned by and in the custody of”) its preceding paean to the importance of preserving passengers’ privacy rings a little hollow on rehearing. Should it not be enough if the passenger says he owns the briefcase, and the officer has no concrete reason to believe otherwise? Or would the dissent consider that an example of “obvious” ownership? On reflection, it seems not at all obvious precisely what constitutes obviousness — and so even the dissent’s on-the-eheap protection of passengers’ privacy interest in their property turns out to be unclear, and hence unadministrable. But maybe the dissent does not mean to propose an obviously-owned-by-and-in-the-eustody-of test after all, since a few sentences later it endorses, simpliciter, “a rule requiring a warrant or individualized probable cause to search passenger belongings,” post, at 312. For the reasons described in text, that will not work.
