Defendants Jose Guzman and Sonia Cruz-Lazo were each charged with one count of possession of cocaine with intent to distribute. The district court granted defendants' motion to suppress evidence uncovered when their car was stopped. The United States appeals, and we remand for further proceedings.
I.
On August 3, 1987, Jose Guzman and his wife, Sonia Cruz-Lazo, were driving a rented 1987 Cadillac with Florida license plates west through New Mexico on Interstate 40. The car was traveling at a lawful speed. New Mexico State Police Officer Keene *1514 testified that he noticed the car because its driver, Guzman, did not appear to be wearing his seat belt, a violation of the state’s traffic regulations.
Officer Keene said that he followed the car for approximately three miles, pulling along side to confirm that the driver was not wearing a seat belt. He then pulled the car over. Guzman got out and approached the officer’s cruiser, while his wife remained in the car. Officer Keene asked Guzman for his license and registration. Guzman gave the officer his license and informed him that the car was rented. Thеy then returned to the car to retrieve the rental agreement.
Officer Keene asked Guzman why Hilario Lazo’s name was on the agreement. Guzman explained that Lazo, his wife’s uncle, had helped them rent the car because they did not have a major credit card of their own. Guzman also pointed out that he was an authorized driver. Officer Keene reviewed the rental agreement and driver’s license, and concluded that both were in order. He then told Guzman that he had stopped him for a seat belt violation.
The officer admitted that at this pоint he had all the necessary information in connection with the violation. Rather than issue a warning or citation, however, he decided to conduct a further investigation. When asked to specify what he was investigating, Officer Keene said he was attempting to determine whether Guzman and Lazo were “hauling contraband in the vehicle.” Rec., supp. vol. I, at 65.
Officer Keene began his supplemental investigation by again approaching defendants’ car, allegedly to check the mileage. While he was comparing the odometer reading to the rental contract, Cruz-Lazo asked why they had been stopped. Officer Keene explained that Guzman had not been wearing his seat belt. He then asked a series of questions. Cruz-Lazo’s replies were consistent with her husband’s prior statement that they were en route from their home in Florida to vacation in Las Vegas. She also stated that they had saved $5000 for the trip.
Officer Keene testified that at the conclusion of his questioning of Cruz-Lazo, his suspicions were aroused. He explained that the noticeably pregnant Cruz-Lazo was perspiring and breathing heavily, whilе Guzman was not. The officer also testified that Cruz-Lazo seemed nervous and avoided making eye contact with him. Based upon these facts, Officer Keene decided to continue the detention. He proceeded to the rear of defendants’ car where Guzman was waiting. He returned the rental contract, but retained Guzman’s driver’s license. While he began to write a warning for the seat belt violation, he continued his interrogation by asking Guzman numerous questions, including: whether his wife was employed, where he was headed, where he worked, when he got married, and if thеy were carrying any large sums of money. After completing the warning and handing it to Guzman, but without advising him that they were free to go, Officer Keene asked if they were carrying weapons or contraband. Guzman replied that they were not hiding anything, and that the officer was free to look.
Officer Keene then handed Guzman his driver’s license and produced a consent to search form, which Guzman executed. The officer searched the trunk and found $5000 hidden in a shoe. He then searched the interior of the car and found a package of cocaine behind the rеar seat. 1 Both defendants disclaimed any knowledge of the contraband. Officer Keene arrested defendants, and they were charged with possessing cocaine with intent to distribute in violation of 21 U.S.C. § 841(a)(1) (1982).
Defendants filed motions to exclude all evidence discovered pursuant to the traffic stop. The motions challenged the legality of the initial stop, the extent of the subsequent seizure and investigation, and the consent to search. After an evidentiary hearing, the court found that the officer’s *1515 testimony lacked credibility and granted the motion on the ground that thе seat belt violation was merely a pretextual justification for an otherwise unconstitutional stop on suspicion of drug possession. The court also concluded that even if the initial stop were legitimate, the officer’s “conduct was entirely beyond reason.” Rec., supp. vol. I, at 94. The court. excluded all evidence discovered during the stop.
II.
A pretextual stop occurs when the police use a legal justification to make the stop in order to search a person or place, or to interrogate a person, for аn unrelated serious crime for which they do not have the reasonable suspicion necessary to support a stop. The classic example, presented in this case, occurs when an officer stops a driver for a minor traffic violation in order to investigate a hunch that the driver is engaged in illegal drug activity. Although no evidence contradicted Officer Keene’s assertion that Guzman was not wearing his seatbelt, the district court found that his purpose in stopping defendants’ car was to investigate criminal drug activity, an intrusion for which the officer did not hаve a reasonable suspicion. Based on the officer’s subjective intent to stop defendants for an unrelated and insupportable reason, the court held the stop 'unconstitutional under the Fourth Amendment. The Government argues that if a driver violates a traffic law, a stop of his car can never be unconstitutional. We are thus presented with the question whether the constitutionality of a pretextual stop should be judged by a subjective or an objective standard.
Most circuits and commentators agree that an objective analysis of the facts and circumstances of a pretextual stop is appropriate, rather than an inquiry into the officer’s subjective intent.
See, e.g., United States v. Causey,
The courts do not agree, however, on what objective elements are dispositive in determining whether a pretextual intrusion is uncоnstitutional. In
United States v. Smith,
In
United States v. Causey,
The pretext doctrine lies at the confluence of two distinct interests. An examination of a police officer’s subjective intent in individual cases would unwisely involve the courts in unproductive inquiries.
See United States v. Arra,
Such arbitrary action is unreasonable within the meaning of the Fourth Amendment.
See
1 W. LaFave,
supra,
§ 1.4(e), at 94-95. It is the heed to restrain the arbitrary exercise of discretionary police power that has been the driving force behind the Court’s decisions forbidding рolice practices not amenable to objective review.
3
See Brown v. Texas,
“given the pervasiveness of such minor offenses and the ease with which law enforcement agents may uncover them in the conduct of virtually everyone, [the requirement of a traffic violation] hardly matters, for ... there exists ‘a power that places the liberty of every man in the hands of every petty officer,’ precisely the kind of arbitrary authority which gave rise tо the Fourth Amendment.”
1 W. LaFave, supra, § 1.4(e), at 95 (quoting 2 L. Wroth & H. Zobel, Legal Papers of John Adams 141-42 (1965)).
Numerous Supreme Court cases recognize that such pretextual use of police power raises a problem of constitutional magni
*1517
tude.
See Steagald v. United States,
For these reasons, we believe the Eleventh Circuit has established the better test for determining whether an investigatory stop is unconstitutional: a court should ask “not whether the officer
could
validly have made the stop, but whether under the same circumstances a reasonable officer
would
have made the stop in the absence of the invalid purpose.”
Smith,
“That an officer theoretically could validly have stopped the car for a possible traffic infraction [i]s not determinative. Similarly immaterial [i]s the аctual subjective intent of the deputy. [A] stop [i]s unreasonable not because the officer secretly hope[s] to find evidence of a greater offense, but because it [i]s clear that an officer would have been uninterested in pursuing the lesser offense absent that hope.”
Id.,
at 710. In other words, “the proper basis of concern is not with
why
the officer deviated from the usual practice in this case but simply that he
did
deviate.” 1 W. LaFave,
supra,
§ 1.4(e), at 94. This test properly preserves the Supreme Court’s requirement of an objective inquiry into Fourth Amendment activity,
see Maryland v. Macon,
The Government objects to any limitation on the exercise of police discretion to utilize minor violations to intrude where probable cause or reasonable suspicion does not otherwise exist, arguing that the police often
*1518
have no other means of enforcing the law. As Justice Scalia wrote for the Court in response to a similar argument, the officer is limited to “followpng] up his suspicions, if possible, by means other than a search.... It may well be that, in [some] circumstances, no effective means short of a search [or seizure] exist[s]. But there is nothing new in the realization that the Constitution sometimes insulates the criminality of a few in order to protect the privacy of us all.”
Arizona v. Hicks,
Contrary to the Government’s argument, our approach will not “severely” curtail “the ability of the New Mexico State Police ... to enforce traffic laws.” Brief of the Appellant — United States of America at 14. No prosecution for violation of a traffic regulation will be affected. Police officers may always issue appropriate citаtions to drivers who violate traffic regulations. Only evidence of a more serious crime discovered pursuant to such a stop will be excluded if the stop was unconstitutionally pretextual.
If police officers in New Mexico are required to and/or do routinely stop most cars they see in which the driver is not wearing his seat belt, then this stop was not unconstitutionally pretextual at its inception, even if Officer Keene subjectively hoped to discover contraband during the stop.
5
Cf. United States v. Corral,
In this case, the district court conducted a subjective inquiry, which we conclude was inappropriate. The only information in the record reflecting general police practice was apparently based upon the district court’s prior experience with this officer rather than testimony abоut general practices. We have neither the evidence nor the necessary findings about objective reasonableness to permit us to apply the appropriate test. We therefore turn to the district court’s alternative holding that even assuming this stop was constitutional at its inception, it quickly exceeded its legitimate scope.
III.
“[I]n determining whether the seizure and search were ‘unreasonable’ our inquiry is a dual one — whether the officer’s action was justified at its inception, and whether it was reasonably related in scope to thе circumstances which justified the interference in the first place.”
Terry v. State of Ohio,
Although “[v]ehicle stops for traffic violations occur countless times each day,”
Prouse,
An officer conducting a routine traffic stop may request a driver’s license and vehicle registration, run a computer check, and issue a citation.
Gonzalez,
In this case, the officer asked for and received a proper license and registration.
Cf. United States v. Obregon,
*1520
At the suppression hearing, Officer Keene attempted to articulate his suspicions by pointing to Cruz-Lazo’s demean- or and her responses to his questions. However, nothing he learned during his investigation created reasonable suspicion to justify a
Terry
-type detention. He claimed that Cruz-Lazo looked sick, seemed apprehensive, was sweating considerably, and did not look him in the eye. He noted that Guzman seemed cool throughout the encounter. He also thought that a laborer and his wife could not have saved $5000 (or $4000 as Guzman stated) for a vacation. Even if such factors might create a reasonable suspicion of something in the appropriate circumstances, they could not do so here. Cruz-Lazo was a noticeably pregnant woman, sitting in a car with the engine off in the middle of the desert several thousand miles from her home. She and her husband had just been stoppеd and were being questioned extensively because her husband had failed to wear his seat belt. Under the circumstances, her actions do not arouse objective suspicion. Furthermore, Officer Keene was unjustified in assuming that a laborer and his wife could not possess $5000 without arousing suspicion
sufficient to justify a seizure.
That Officer Keene’s “ ‘hunch’ about [defendants] proved correct is perhaps a tribute to his policeman’s intuition, but it is not sufficient to justify,
ex post facto,
a seizure that was not objectively reasonable.”
Smith,
IV.
The Government argues alternatively that Guzman’s consent legitimized the search of the car. However, the district court made no findings on the issuе of consent, which is a question of fact.
See Schneckloth v. Bustamonte,
This Circuit has held that when a consent to search is preceded by a Fourth Amendment violation, the consent is valid only if it is voluntary in fact.
9
United States v. Carson,
In
Brown v. Illinois,
The court below made no findings as to the voluntariness of the consent in this case. Voluntariness is a finding of fact, to be determined under the totality of the circumstances.
Schneckloth,
The judgment below is vacated, and the case is remanded for proceedings consistent with this opinion.
Notes
. Subsequent searches revealed approximately five kilograms of cocaine and $40,000 in cash behind the rear seat and the dashboard.
. In his special concurrence in
Causey,
Judge Higginbotham expressed concern that "with the storage and retrieval capabilities of today’s computers, warrants may functiоn in a manner similar to the old general writs of assistance."
. We note that the decisions in
Scott
v.
United States,
. Two such exceptions are the plain view and inventory search doctrines. Although a majority of the Court has never agreed on the prerequisites needed to justify the admission of evidence discovered in plain view, an integral part of the established rule is that "the officer must discover incriminating evidence ‘inadvertently’ which is to say, he may not ‘know in advance the location of [certain] evidence and intend to seize it,’ relying on the plain view doctrine only as a pretext.”
Texas v. Brown,
. Supreme Court cases dealing with traffic stops approve of this view. When police discretion is limited by standardized procedures, the Court has approved limited warrantless intrusions.
See United States v. Martinez-Fuerte,
. We adopted this analysis in Lessman where we said:
“It would be relevant to know whethеr the Topeka police, routinely or even occasionally, go to a person’s home to make an arrest upon a violation for overtime parking. If this is never done unless there is a large accumulation of tickets, then although the warrant would be valid, it could still be an abuse of power.”
. Although exceptions to normal Fourth Amendment requirements exist for automobiles, " ‘[t]he 'grave danger’ of abuse of discretion does not disappear simply because the automobile is subject to state regulation resulting in numerous instances of police-citizen contact."
Prouse,
. The Government stresses that this traffic stop took less than fifteen minutes. As the Supreme Court made clear in
United States v. Sharpe,
. Voluntariness in fact under the Fourth Amendment is contrasted with Fifth Amendment voluntariness. In
Brown v. Illinois,
. Where the proceeding below “resulted in a record of amply sufficient detail and depth from which the determination may be made,” the appellate court may conduct this analysis.
