Jеsus Cardenas-Alatorre seeks reversal of his conviction for possession with intent to distribute a substantial quantity of methamphetamine, contending primarily that the statute under which he was stopped while driving on a New Mexico highway is unconstitutionally vague and, therefore, the drugs discovered pursuant to that stop should have been suppressed. The state statute in question makes it a misdemeanor for a car’s license plate to be obscured by “foreign material,” at least in any way that renders the plate less than “clearly legible.” Reluctаnt to venture into constitutional thickets unnecessarily, we hold that, whatever the constitutional status of the statute in question, the arresting officer acted in an objectively reasonable manner and, under Supreme Court precedent, this suffices to permit the fruits of the search to be used against Mr. Cardenas-Alatorre. It is on this basis that we affirm his conviction.

Around noon on May 11, 2005, Deputy Peter Roth of the Bernalillo County Sheriffs Department stopped Mr. Cardenas-Alatorre on Interstate 40 just outside of Albuquerque, New Mexico. Appellant’s Br. 3; Tr. at 9-11. 1 Deputy Rоth testified that he pulled over Mr. Cardenas-Alatorre because a license plate frame, one of those supplied by auto dealers anxious for free advertising, obscured a portion of the license plate on his car — specifically, the entirety of the name of the state of registration, Arizona. Tr. at 10. This, Deputy Roth believed, constituted a violation of a New Mexico statute requiring a license plate to be attached to the rear of every vehicle that is “clearly visible[ ] and ... free from foreign materiаl and in a condition to be clearly legible.” N.M. Stat. Ann. § 66-3-18(A) (1998 N.M. Laws, Ch. 48, § 4 (eff. July 1,1998)) (in effect on May 11, 2005). 2 The license plate frame did not, however, obscure other pertinent information, including the license plate number, the registration stickers, the image of the distinctive Arizona saguaro cactus, or the top half of the state’s “Grand Canyon State” motto. Tr. at 37-40; Def.’s Ex. A. During questioning by the district court judge, Deputy Roth admitted that, based on the information that was visible, the *1113 license plate “appeared” to be issued by Arizona, though he had qualms it might be “fictitious” because he cоuld not see the word “Arizona.” Tr. at 40.
During the ensuing conversation with Mr. Cardenas-Alatorre, Deputy Roth expressed his concern about the obscuring license plate frame and then asked for, and obtained, Mr. Cardenas-Alatorre’s vehicle registration, insurance information, and driver’s license. Tr. at 12-13. 3 In doing so, Deputy Roth detected that “there was an extreme odor of air freshener which is, in my past experience, a masking agent” for drugs; he also thought Mr. Cardenas-Alatorre appeared “extremely nervous.” Id. at 14-15. Accordingly, Deputy Roth orderеd Mr. Cardenas-Alatorre to step out of the vehicle. Id. at 18. After conducting a computer investigation in his patrol car, Deputy Roth confirmed that the car driven by Mr. Cardenas-Alatorre was not stolen and no outstanding warrants existed for either Mr. Cardenas-Alatorre or his passenger, Felis Sosa-Reyes. Id. at 21. Deputy Roth then turned on the video camera affixed to his patrol car, returned Mr. Cardenas-Alatorre’s documents, and issued Mr. Cardenas-Alatorre a citation for failure to display the license plate properly. Id. at21-22. 4
As the traffic stоp wound down, Deputy Roth asked Mr. Cardenas-Alatorre if he could speak with him further, to which Mr. Cardenas-Alatorre responded, “About?” Id. at 28, 88-89. Deputy Roth replied by asking whether Mr. Cardenas-Alatorre had any illegal items inside the car, including drugs, to which Mr. Cardenas-Alatorre answered in the negative. Id. at 24-26, 58-59. Deputy Roth next sought permission to search the vehicle. Mr. Cardenas-Alatorre variously shrugged and nodded his head affirmatively in response. Id. at 25-26, 59-60; see generally DVD. Deputy Roth asked the question again and Mr. Cardenas-Alatorre then verbally responded definitively, yes. Id. at 60-61. 5 At about this point, New Mexiсo State Police Sergeant Rudy Mora, who had been patrolling the area independently, saw Deputy Roth’s car and stopped at the scene. Id. at 27-28, 99. Sergeant Mora had with him a trained narcotics detection dog. Id. at 27, 99-100; DVD. As Sergeant Mora walked the dog around the perimeter of the vehicle, the dog alerted to the area near the glove box. Tr. at 100-03. Deputy Roth then searched that area and found two wrapped packages containing methamphetamine. Id. at 31-33.
Mr. Cardenas-Alatorre moved the district court to suрpress the methamphetamine seized during the traffic stop and to dismiss the indictment. In support of these motions, Mr. Cardenas-Alatorre argued (i) that the traffic stop was an unlawful seizure because it was based upon an unconstitutionally vague statute; (ii) even assuming the statute were constitutional, Deputy Roth did not have reasonable suspicion to stop Mr. Cardenas-Alatorre because he did not violate the statute; and (iii) Mr. Cardenas-Ala-torre did not voluntarily consent to the search of his car. The district court rejected these arguments and Mr. Cardenas-Alatorre thereafter pled guilty sub *1114 ject to his right to appeal the district court’s denial of his motions. Appellee’s Br. 6. 6
II
Before us, Mr. Cardenas-Alatorre argues primarily that the fruits of the officers’ search of his car should be suppressed because the New Mexico statute at issue, at least as applied,
7
is unconstitutional. Mr. Cardenas-Alatorre submits that the statute is so opaque that police officers and prosecutors can use it as something of a blank slate on which to write their own private conceptions of what the law ought to be, thereby effecting traffic stops capriciously and in violation of the Constitution’s prohibition against statutes of “standardless sweep” that fail to establish “minimal guidelines to govern law enforcement.”
Kolender v. Lawson,
The curative aim of the void for vagueness doctrine is vital and twofold, seeking to ensure that penal statutes “define the criminal offense with sufficient definiteness” in order both to apprise the citizenry of what conduct is prohibited and to prevent police from arbitrarily enforcing the laws and thereby effectuating a form of state-sanctioned discrimination.
Kolender, 461
U.S. at 357,
But this remedy is not exceptionless. The Supreme Court has repeatedly instructed that the exclusionary rule ought not to be deployed when officers act in good faith&emdash;that is, in “objectively reasonable reliance” upon a statute&emdash;even though
*1115
the statute ultimately may be found unconstitutional.
Krull,
We find this exception applicable and dispositive here. Even assuming (without deciding) that Mr. Cardenas-Ala-torre is correct that the New Mexico statute is unconstitutional as applied to him, we are unable to conclude that Deputy Roth acted in an objectively unreasonable manner. 9 Although the statute’s opening directive that license plates must be located “in a place and position so as to be clearly visible,” might not, when read in isolation, be the most specific statutory command known to bar and bench, the following clause adds that the plate must “be maintained free from foreign material and in a condition to be clearly legible.” This latter language arguably complements what precedes, narrowing the contours of the conduct prohibited by the statute. 10 Under this view, the law, taken as a whole, sets out to prosсribe “foreign material” (including the auto dealer’s advertising frame) to the extent that it prevents all of the plate from being clearly legible&emdash;that is, readable. 11
This understanding of the statute&emdash;al-lowing officers to effect stops only when foreign material prevents them from reading the information contained on a license plate&emdash;would seem to channel and constrain the discretion of law enforcement at least to a sufficient degree that we would be unable to say that the law lacks “minimal guidelines.”
Kolender,
Our conclusion is confirmed, indeed compelled, by the Supreme Court’s application of the good faith exception to a parallel vagueness challenge in
Michigan v. DeFillippo,
[plolice are charged to enforce laws until and unless they are declared unconstitutional. The enactment of a law forecloses speculation by enforcement officers concerning its constitutionality— with the possible exception of a law so grossly and flagrantly unconstitutional that any person of reasonable prudence would be bound to see its flaws. Society would be ill-sеrved if its police officers took it upon themselves to determine which laws are and which are not constitutionally entitled to enforcement.

Alternatively, and in tension with his argument that the New Mexico statute is vague, Mr. Cardenas-Alatorre contends that the purpose of the law is merely and specifically to ensure that cars driven on New Mexico highways are properly registered; that the statute is narrowly tailored to accomplish this purpose by requiring visibility only of information necessary to determine the state of issuance, the license plate number, and registration status; and *1118 that all this information was clearly visible on Mr. Cardenas-Alatorre’s plate. Appellant’s Br. 34-38. Even without the word “Arizona” visible, Mr. Cardenas-Alatorre argues, Deputy Roth “admitted” thаt the plate was an Arizona plate by virtue of other markings on it and could see that the registration tags were current. Id. All this, Mr. Cardenas-Alatorre submits, compels us to find that he had effectively complied with the New Mexico statute and, accordingly, his traffic stop was objectively unreasonable under the Fourth Amendment.
As it happens, however, instead of “admitting” that he knew the license plate to be a valid Arizona plate, Deputy Roth testified that the plate appeared to be valid, adding that, because the word “Arizona” was covered, he remained concerned, based on past experiеnce, that the plate may have been fraudulent. See supra p. 3. We must also disagree with Mr. Cardenas-Alatorre’s (current) pinched reading of the statute as seeking only to ensure that officers can ascertain whether a car’s registration tags are current. As we have already indicated above, the statute has a broader sweep, making it unlawful, at the minimum, to render any writing on a license plate illegible (that is, unreadable) by virtue of the presence of “foreign material”; indeed, it is precisely because of the breadth of the statute that wе emphasize the limits of our decision in Part II and the fact that the constitutionality of the law remains open to challenge. 16
IV
Finally, Mr. Cardenas-Alatorre submits that, even if the initial stop itself was valid, the scope and duration of his detention were excessive because he did not voluntarily consent to Deputy Roth’s continued questioning at the conclusion of the traffic citation process. Appellant’s Br. 39.
In assessing Mr. Cardenas-Alatorre’s claim, we note that, under our precedents, if, at the conclusion of a traffic stop a driver voluntаrily consents to further questioning, no seizure takes place and “the Fourth Amendment’s strictures are not implicated.”
United States v. Elliott,
Mr. Cardenas-Alatorre first argues that Ms response to Deputy Roth’s request to question him — “About?”—by its plain terms did not amount to consent to further questioning. Reply Br. 14-15. While Mr. Cardenas-Alatorre’s contention has a certain appeal, the district court construed the remark and surrounding events somewhat differently, interpreting Mr. Cardenas-Alatorre as having consented to continue his discussion with Deputy Roth though also as reserving the right not to answer depending upon the pаrticular question asked:
“About?” means to me: “What do you want to talk to me about?” It’s pretty clear.... If he didn’t want to answer, he doesn’t have to answer. That’s up to him. But he answered and he gave consent to search the ear.
Tr. at 145. Mr. Cardenas-Alatorre identifies no convincing reason for us to reject this interpretation as clearly erroneous. Merely providing an alternative interpretation of the facts, as he does, will not suffice.
See Watson,
Next, Mr. Cardenas-Alatorre submits that, even if he did consent to further questioning, his consent was involuntarily extracted. In support of this argument, Mr. Cardenas-Alatorre directs us to Deputy Roth’s failure to tell the defendant he was free to leave; the “barrage of questions” Deputy Roth asked; Deputy Roth’s tone of voice; and Sergeant Mora’s arrival with a barking drug detection dog. Appellant’s Br. 42. 17 The district court did not make any specific findings on these matters, but its more general finding that Mr. Cardenas-Alatorre “gave consеnt to search the car,” Tr. at 145, necessarily implies a rejection of the defendant’s version of events, and we are obliged to “affirm the district court’s suppression ruling if any reasonable view of the evidence supports that ruling.” United States v. King, 222 F.3d 1280, 1283 n. 2 (10th Cir.2000) (citations omitted).
We have viewed the DVD supplied by counsel recording the traffic encounter between Mr. Cardenas-Alatorre and Deputy Roth, and it simply fails to reflect the sort of coercive atmosphere Mr. Cardenas-Ala-torre describes. Deputy Roth returned Mr. Cardenas-Alatorre’s documents and issued the citation bеfore seeking permission to ask further questions; he employed no intimidating body language or tone; and he did not block or otherwise prevent Mr. Cardenas-Alatorre from returning to his car. An illustration of the relaxed tenor of their conversation was Deputy Roth’s'joke, while casually tugging at his belt, that he is “a little fat,” to which Mr. Cardenas-Alatorre laughed and responded in kind, “I’m a little fat, also.” Tr. at 52. The video recording also indicates that, while Sergeant Mora arrived on the scene as this discussion took place, Mr. Cardenas-Alatorre’s back was fаcing the direction from which Sergeant Mora arrived; thus, neither Sergeant Mora nor his dog
*1120
were even visible to Mr. Cardenas-Ala-torre when Deputy Roth requested permission to search.
See United States v. Manjarrez,
For the foregoing reasons, the judgment of the district court is
Affirmed.

.Not incidentally, vague laws also pose a danger to separation of powers: " 'if the legislature could set a net large enough to catch all possible offenders, and leave it to the courts to step inside and say who could be rightfully detained, and who should be set at large[, t]his would, to some extent, substitute the judicial for the legislative department of government’ ”

The legitimacy of an officer's rejection of a directive is further complicated where, as here, the “order” emanates from a law created through a democratic process — for the legislation represents an issue that "has already been decided by the people” through their freely elected representatives.
