At 7:20 p. m. on November 30, 1976, a New Castle County, Del., patrolman in a police cruiser stopped the automobile occupied by respondent.1 The patrolman smelled marihuana smoke as he was walking toward the stopped vehicle, and he seized marihuana in plain view on the car floor. Respondent was subsequently indicted for illegal possession of a controlled substance. At a hearing on respondent‘s motion to suppress the marihuana seized as a result of the stop, the patrolman testified that prior to stopping the vehicle he had observed neither traffic or equipment violations nor any suspicious activity, and that he made the stop only in order to check the driver‘s license and registration. The patrolman was not acting pursuant to any standards, guidelines, or procedures pertaining to document spot checks, promulgated by either his department or the State Attorney General. Characterizing the stop as “routine,” the patrolman explained, “I saw the car
The Delaware Supreme Court affirmed, noting first that “[t]he issue of the legal validity of systematic, roadblock-type stops of a number of vehicles fоr license and vehicle registration check is not now before the Court,” 382 A. 2d 1359, 1362 (1978) (emphasis in original). The court held that “a random stop of a motorist in the absence of specific articulable facts which justify the stop by indicating a reasonable suspicion that a violation of the law has occurred is constitutionally impermissible and violative of the

In this case, however, the State of Delaware urges that patrol officers be subject to no constraints in deciding which automobiles shall be stopped for a license and registration check because the State‘s interest in discretionary spot checks as a means of ensuring the safety of its roadways outweighs the resulting intrusion on the privacy аnd security of the persons detained.
IV
We have only recently considered the legality of investigative stops of automobiles where the officers making the stop have neither probable cause to believe nor reasonable suspicion that either the automobile or its occupants are subject to seizure under the applicable criminal laws. In United States v. Brignoni-Ponce, supra, Border Patrol agents conducting roving patrols in areas near the international border asserted statutory authority to stop at random any vehicle in order to determine whether it contained illegal aliens or was involved in smuggling operations. The practicе was held to violate the
“Except at the border and its functional equivalents, officers on roving patrol may stop vehicles only if they are
aware of specific articulable facts, together with rational inferences from those facts, that reasоnably warrant suspicion that the vehicles contain aliens who may be illegally in the country.” 422 U. S., at 884 (footnote omitted).
Because “the nature of illegal alien traffic and the characteristics of smuggling operations tend to generate articulable grounds for identifying violators,” id., at 883, “a requirement of reasonable suspicion for stops allows the Government adequate means of guarding the public interest and also protects residents of the border areas from indiscriminate official interference.” Ibid.
The constitutionality of stops by Border Patrol agents was again before the Court in United States v. Martinez-Fuerte, supra, in which we addressed the permissibility of checkpoint operations. This practice involved slowing all oncoming traffic “to a virtual, if not a complete, halt,” 428 U. S., at 546, at a highway roadblock, and referring vehicles chosen at the discretion of Border Patrol agents to an area for secondary inspection. See id., at 546, 558. Recognizing that the governmental interest involved was the same as that furthered by roving-patrol stops, the Court nonetheless sustained the constitutionality of the Border Patrol‘s checkpoint operations. The crucial distinction was the lesser intrusion upon the motorist‘s Fourth Amendment interests:
“[The] objective intrusion—the stop itself, the questioning, and the visual inspection—also existed in roving-patrol stops. But we view сheckpoint stops in a different light because the subjective intrusion—the generating of concern or even fright on the part of lawful travelers—is appreciably less in the case of a checkpoint stop.” Id., at 558.
Although not dispositive,13 these decisions undoubtedly pro-

But the State of Delaware urges that even if discretionary spot checks such as occurred in this case intrude upon motorists as much as or more than do the roving patrols held impermissible in Brignoni-Ponce, these stops are reasonable under the
The question remains, however, whether in the service of these important ends the discretionary spot check is a sufficiеntly productive mechanism to justify the intrusion upon
The foremost method of enforcing traffic and vehicle safety regulations, it must be recalled, is acting upon observed violations. Vehicle stops for traffic violations occur countless times each day; and on these occasions, licenses and registration papers are subject to inspection and drivers without them will be ascertained. Furthermore, drivers without licenses are presumably the less safe drivers whose propensities may well exhibit themselves.19 Absent some empirical data to the contrary, it must be assumed that finding an unlicensed driver among those who commit traffic violations is a much more likely event than finding an unlicensed driver by choosing randomly from the entire universe of drivers. If this were not so, licensing of drivers would hardly be an effective means of promoting roadway safety. It seems common sense that the
Much the same can be said about the safety aspects of automobiles as distinguished from drivers. Many violations of minimum vehicle-safety requirements are observable, and something can be done about them by the observing officer, directly and immediately. Furthermore, in Delaware, as elsewhere, vehicles must carry and display current license plates,20 which themselves evidence that the vehicle is prоperly registered;21 and, under Delaware law, to qualify for annual registration a vehicle must pass the annual safety inspection22 and be properly insured.23 It does not appear, therefore, that a stop of a Delaware-registered vehicle is necessary in order to ascertain compliance with the State‘s registration requirements; and, because there is nothing to
The marginal contribution to roadway safety possibly resulting from a system of spot checks cannot justify subjecting every occupant of every vehicle on the roads to a seizure—limited in magnitude compared to other intrusions but nonetheless constitutionally cognizable—at the unbridled discretion of law enforcement officials. To insist neither upon an appropriate factual basis for suspicion directed at a particular automobile nor upon some other substantial and objective standard or rule to govern the exercise of discretion “would invite intrusions upon constitutionally guaranteed rights based on nothing more substantial than inarticulate hunches....” Terry v. Ohio, 392 U. S., at 22. By hypothesis, stopping apparently safe drivers is necessary only because the danger presented by some drivers is not observable at the time of the stop. When there is not probable cause to believe that a driver is violating any one of the multitude of applicable traffic and equipment regulations24 or other articulable basis amounting to reasonable suspicion that the driver is unlicensed or his vehicle unregistered—we cannot conceive of any legitimate basis upon which a patrolman could decide that stopping a particular driver for a spot check would be more productive than stopping any other driver. This kind of standardless and unconstrained discretion is the evil the Court has discerned when in previous cases it has insisted that the discretion of the official in the field be circumscribed, at least to some extent. Almeida-Sanchez v. United States, 413 U. S. 266, 270 (1973); Camara v. Municipal Court, 387 U. S., at 532-533.
VI
The “grave danger” of abuse of discretion, United States v. Martinez-Fuerte, 428 U. S., at 559, does not disappear simply because the automobile is subject to state regulation resulting in numerous instances of police-citizen contact, Cady v. Dombrowski, 413 U. S. 433, 441 (1973). Only last Term we pointed out that “if the government intrudes . . . the privacy interest suffers whether the government‘s motivation is to investigate violations of criminal laws or breaches of other statutory or regulatory standards.” Marshall v. Barlow‘s, Inc., 436 U. S., at 312-313. There are certain “relatively unique circumstances,” id., at 313, in which consent to regulatory restrictions is presumptively concurrent with participation in the regulated enterprise. See United States v. Biswell, 406 U. S. 311 (1972) (federal regulation of firearms); Colonnade Catering Corp. v. United States, 397 U. S. 72 (1970) (federal regulation of liquor). Otherwise, regulatory inspections unaccompanied by any quantum of individualized, articulable suspicion must be undertaken pursuant to previously specified “neutral criteria.” Marshall v. Barlow‘s, Inc., supra, at 323.
An individual operating or traveling in an automobile does not lose all reasonable expectation of privacy simply because the automobile and its use are subject to government regulation.25 Automobile travel is a basic, pervasive, and often necessary mode of transportation to and from one‘s home, workplace, and leisure activities. Many people spend more hours each day traveling in cars than walking on the streets. Undoubtedly, many find a greater sense of security and privacy in traveling in an automobile than they do in exposing themselves by pedestrian or other modes of travel. Were the

Accordingly, we hold that except in those situations in which there is at least articulable and reasonable suspicion that a motorist is unlicensed or that an automobile is not registered, or that either the vehicle or an occupant is otherwise subject to seizure for violation of law, stopping an automobile and detaining the driver in order to check his driver‘s license and the registration of the automobile are unreasonable under the

With this understanding, I join the Court‘s opinion and its judgment.
MR. JUSTICE REHNQUIST, dissenting.
The Court holds, in successive sentences, that absent an articulable, reasonable suspicion of unlawful conduct, a motorist may not be subjected to a random license check, but that the States are free to develop “methods for spot checks that . . . do not involve the unconstrained exercise of discretion,” such as “[q]uestioning . . . all oncoming traffic at roadblock-type stops . . . .” Ante, at 663. Because motorists, apparently like sheep, are much less likely to be “frightened” or “annoyed” when stopped en masse, a highway patrolman needs neither probable cause nor articulable suspicion to stop all motorists on a particular thoroughfare, but he cannot without articulable suspicion stop less than all motorists. The Court thus elevates the adage “misery loves company” to a novel role in
As the Court correctly points out, people are not shorn of their
In executing this balancing process, the Court concludes that given the alternative mechanisms available, discretionary spot checks are not a “sufficiently productive mеchanism” to safeguard the State‘s admittedly “vital interest in ensuring that only those qualified to do so are permitted to operate motor vehicles, that these vehicles are fit for safe operation, and hence that licensing, registration, and vehicle inspection requirements are being observed.” Ante, at 659, 658. Foremost among the alternative methods of enforcing traffic and vehicle
*Indeed, this distinction was expressly recognized in United States v. Brignoni-Ponce, 422 U. S. 873, 883 n. 8 (1975):
“Our decision in this case takes into account the special function of the Border Patrol, the importance of the governmental interests in policing the border area, the character of roving-patrol stоps, and the availability of alternatives to random stops unsupported by reasonable suspicion. Border Patrol agents have no part in enforcing laws that regulate highway use, and their activities have nothing to do with an inquiry whether motorists and their vehicles are entitled, by virtue of compliance with laws governing highway usage, to be upon the public highways. Our decision thus does not imply that state and local enforcement agencies are without power to conduct such limited stops as are necessary to enforce laws regarding drivers’ licenses, vehicle registration, truck weights, and similar matters.”
Nor is the Court impressed with the deterrence rationale, finding it inconceivable that an unlicensed driver who is not deterred by the prospect of being involved in a traffic violation or other incident requiring him to produce a license would be deterred by the possibility of being subjected to a spot check. The Court arrives at its conclusion without the benefit of a shred of empirical data in this record suggesting that a system of random spot checks would fail to deter violators. In the absence of such evidence, the State‘s determination that random stops would serve a deterrence function should stand.
On the other side of the balance, the Court advances only the most diaphanous of citizen interests. Indeed, the Court does not say that these interests can never be infringed by the State, just that the State must infringe them en masse rather than citizen by citizen. To comply with the
Neither the Court‘s opinion, nor the opinion of the Supreme Court of Delaware, suggests that the random stop made in this case was carried out in a manner inconsistent with the
