OPINION ON REMAND
MURPHY, Circuit Judge.
I. Introduction1
Roland Lorenzo Mitchell filed an untimely notice of appeal of his conviction for possession of marijuana with intent to distribute. This court dismissed his appeal, sua sponte, for lack of jurisdiction because Mitchell failed to comply with the time limitations of Federal Rule of Appellate Procedure 4(b). United States v. Mitchell, 464 F.3d 1149, 1149 (10th Cir.2006). The Supreme Court vacated our decision and remanded for further consideration in light of Bowles v. Russell, — U.S. —, 127 S.Ct. 2360, 2366, 168 L.Ed.2d 96 (2007) (holding the timeliness requirements in Fed. RApp. P. 4(a) are jurisdictional because they derive from a statute). Mitchell v. United States, — U.S. —, 127 S.Ct. 2973, 2973, 168 L.Ed.2d 701 (2007). Upon further consideration, we reach the merits of Mitchell’s appeal because the government forfeited its objection to the untimely notice of appeal and sua sponte dismissal under Rule 4(b) would be inappropriate.
II. Background
Mitchell, a long haul truck driver, was arrested at the Eastbound Motor Trans[743]*743portation Division Port of Entry in Lords-burg, New Mexico.2 Pursuant to N.M. Stat. Ann. § 65-5-1, officers from the New Mexico Department of Public Safety approached Mitchell’s tractor-trailer for inspection. Mitchell told the officers he was traveling from Phoenix, Arizona to Atlanta, Georgia with an empty trailer. On review of Mitchell’s log book, the officers conducting the inspection determined it contained inaccuracies and evidence of falsification. In response to questioning, Mitchell told the officers he was going to pick up a cargo load at a nearby truck stop. An officer, however, had personal knowledge that particular truck stop did not have a loading dock and was essentially a convenience store.
The officers requested that Mitchell open the trailer to confirm it was empty. The opened door revealed five boxes, which Mitchell claimed contained “parts.” The officer asked Mitchell to open the boxes to verify the contents. Mitchell replied he was not sure that was a good idea. The officer asked again and Mitchell consented. The boxes contained marijuana.
Mitchell was charged with possession of more than 100 kilograms of marijuana with intent to distribute in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(B). The district court denied his motion to suppress the marijuana, holding the search did not violate the Fourth Amendment. Mitchell entered into a conditional guilty plea, reserving his right to appeal the district court’s decision on the motion to suppress. The district court sentenced Mitchell to sixty months’ imprisonment.
Although judgment was entered in Mitchell’s case on February 9, 2005, a notice of appeal was not filed until February 25, 2005, one day outside the ten-day period allowed under Federal Rule of Appellate Procedure 4(b)(1).3 Mitchell filed a contemporaneous motion in the district court seeking an extension of time to file the notice of appeal due to excusable neglect. Fed. R.App. P. 4(b)(4). The district court granted the motion. In this court, both Mitchell and the government briefed the merits of the appeal, but did not address whether the district court erred in granting Mitchell’s motion for an extension to file the notice of appeal. This court, recognizing that the motion may have been improperly granted, raised the issue at oral argument sua sponte.4
This panel issued an opinion in Mitchell’s case in September of 2006 holding as a matter of law that Mitchell’s untimely notice of appeal was not the result of excusable neglect and dismissing the appeal for lack of jurisdiction. Mitchell, 464 F.3d at 1149. As noted above, this matter is now before us on remand from the Supreme Court for reconsideration in light of Bowles v. Russell, 127 S.Ct. at 2360. Mitchell, 127 S.Ct. at 2973.
III. Effect of an Untimely Notice of Appeal
The time bar of the Federal Rules of Appellate Procedure for the filing of a notice of appeal in a criminal case was long [744]*744considered “mandatory and jurisdictional.” Wilkinson v. United States, 278 F.2d 604, 605 (10th Cir.1960) (per curiam) (citing United States v. Robinson, 361 U.S. 220, 224, 80 S.Ct. 282, 4 L.Ed.2d 259 (1960)). The Supreme Court’s recent decision in Bowles, however, clarified that court-issued federal procedural rules not derived from statutes are not jurisdictional, but rather inflexible claim-processing rules. 127 S.Ct. at 2363-66. This court recently held that, in light of Bowles, Federal Rule of Appellate Procedure 4(b)(1) is a claim-processing rule. United States v. Garduno, 506 F.3d 1287, 1288-89 (10th Cir.2007). As a result, dismissal of Mitchell’s appeal, based on his failure to file a timely notice of appeal, is no longer mandatory and jurisdictional.
Nevertheless, the time bar in Rule 4(b) must be enforced by this court when properly invoked by the government. Garduño, 506 F.3d at 1290-91; see Eberhart v. United States, 546 U.S. 12, 19, 126 S.Ct. 403, 163 L.Ed.2d 14 (2005) (“These claim-processing rules thus assure relief to a party properly raising them.”). In this case the government never objected to the untimeliness of Mitchell’s notice of appeal and, as a result, forfeited its opportunity to ensure enforcement of the rule.5 Although it acknowledges that after Bowles this court has no obligation to raise the issue of timeliness, the government maintains this court could and should raise and decide the issue sua sponte.
We begin this analysis by noting that this area of the law has been in flux since Kontrick v. Ryan, 540 U.S. 443, 124 S.Ct. 906, 157 L.Ed.2d 867 (2004), and Eberhart v. United States, 546 U.S. at 12, 126 S.Ct. 403, first indicated the time limitations in the federal rules may not be jurisdictional under some circumstances. As a result, there is limited case law indicating how the courts should enforce those rules which are no longer jurisdictional. The question of whether a court may sua sponte raise timeliness under Rule 4(b) is one of first impression in this circuit and appears to have only been addressed tangentially in other circuits.6 See Wilburn v. [745]*745Robinson, 480 F.3d 1140, 1143-48 (D.C.Cir.2007).
A
Kontrick and Eberhart do not specifically speak to the issue of whether a court may sua sponte raise timeliness under non-jurisdictional federal rules. They generally indicate, however, that claim-processing rules must be raised by the parties. In Kontrick, which involved the time constraints of Bankruptcy Rule 4004 governing when a party must file a complaint objecting to a debtor’s discharge, the party seeking to assert the time bar waited until after the matter had been fully adjudicated on the merits. 540 U.S. at 451, 124 S.Ct. 906. The Court analogized the time bar in the Bankruptcy Rules to affirmative defenses governed by Fed.R.Civ.P. 8(c), stating “under the Bankruptcy Rules as under the Civil Rules, a defense is lost if it is not included in the answer or amended answer.” 540 U.S. at 459, 124 S.Ct. 906. By invoking the affirmative defense provision of the Federal Rules of Civil Procedure, the Court implied that failure to raise a timeliness constraint amounts to a forfeiture of the issue. See Bentley v. Cleveland County Bd. of County Comm’rs, 41 F.3d 600, 604 (10th Cir.1994) (“Failure to plead an affirmative defense results in a waiver of that defense.”). The Court in Kontrick did not address whether the district court could raise Rule 4004 sua sponte. Nevertheless, as courts generally may not raise affirmative defenses sua sponte, Kontrick may imply courts cannot raise time bars in claim-processing federal rules. See Eri-line Co. S.A. v. Johnson, 440 F.3d 648, 653-56 (4th Cir.2006).
In Eberhart, the Court expanded on its holding in Kontrick by ruling that Fed. R.Crim.P. 33(a), which includes time limitations for filing new-trial motions, is a claim-processing rule. 546 U.S. at 13, 126 S.Ct. 403. In that case, the government raised for the first time on appeal an objection to the defendant’s failure to comply with the time limitations of Rule 33(a). Id. at 14, 126 S.Ct. 403. The Court held, “[h]ere, where the Government failed to raise a defense of untimeliness until after the District Court had reached the merits, it. forfeited that defense. The Court of Appeals should therefore have proceeded to the merits.” Id. at 19, 126 S.Ct. 403. The implication from this language may be that a court does not have the option to raise the timeliness issue sua sponte.
Both Kontrick and Eberhart, however, can be distinguished from the case before this court. Most notably, Kontrick and Eberhart involved rules that apply at the trial level where Fed.R.Civ.P. 8(c) operates as the mechanism for pleading affirmative defenses.7 There is no analogous rule at the appellate level. Furthermore, in both Kontrick and Eberhart the timeliness issue was not raised until after the dispute had been adjudicated on the merits. That is not the case here as this court recognized the timeliness issue before proceeding to the merits. Mitchell, 464 F.3d at 1149.
The government relies on Day v. McDonough, 547 U.S. 198, 126 S.Ct. 1675, 164 L.Ed.2d 376 (2006), as support for its argument that despite Kontrick and Eber-[746]*746hart this court may raise sua sponte the timeliness of a notice of appeal. The justifications for the result in Day, however, are unique to the habeas corpus context and have limited applicability to the case at bar. Day presented the question of whether a federal district court may sua sponte dismiss a habeas petition as untimely for failure to comply with the time bars of the AEDPA after the state has answered the petition without raising a timeliness objection. 547 U.S. at 201, 126 S.Ct. 1675. Although recognizing district courts were not obligated to raise the non-jurisdictional statute of limitations, the Court held district courts may raise the time bar sua sponte provided the parties have been accorded fair notice and opportunity to present their positions. Id. at 206, 210, 126 S.Ct. 1675.
In reaching its holding, the Court explained why the usual practice of requiring the parties to plead all affirmative defenses did not apply under these circumstances. First, the Court drew parallels between AEDPA’s time bar and other affirmative defenses unique to the habeas context such as exhaustion of state remedies, procedural default, and non-retroactivity, all of which may be may be raised by a court sua sponte under current precedent.8 Id. at 205-06, 209, 126 S.Ct. 1675. Second, the Court recognized that “[t]he considerations of comity, finality, and the expeditious handling of habeas proceedings that motivated AEDPA ... counsel against an excessively rigid or formal approach to the affirmative defenses.” Id. at 208, 126 S.Ct. 1675 (footnote omitted). Third, the Court noted that consistent with the Rules of Civil Procedure and the statutes governing habeas petitions, the district court could have brought the matter of the limitations period to the attention of the state and entertained an amendment to the state’s answer. Id. at 209, 126 S.Ct. 1675. In light of this extant procedural avenue, the Court concluded it would elevate form over substance if it were to disallow district courts to raise the limitations issue sua sponte. Id.
At the core of the Court’s opinion in Day is the notion that habeas proceedings are different from ordinary civil litigation and, as a result, our usual presumptions about the adversarial process may be set aside. See 547 U.S. at 202, 126 S.Ct. 1675. The rationales offered by the Court in Day are therefore not necessarily applicable to the case before this court. Rule 4(b) is not analogous to the AEDPA-based affirmative defenses at issue in Day. AEDPA is a unique statutory regime which implicates overarching values of federalism, comity, and finality of state court judgments.9 Rhines v. Weber, 544 U.S. 269, 276, 125 S.Ct. 1528, 161 L.Ed.2d 440 (2005) (“One [747]*747of the statute’s purposes is to reduce delays in the execution of state and federal criminal sentences.” (quotation omitted)); Williams v. Taylor, 529 U.S. 420, 436-37, 120 S.Ct. 1479, 146 L.Ed.2d 435 (2000) (noting court-created affirmative defenses such as exhaustion requirements and procedural bar advance these purposes). AEDPA’s statute of limitations itself serves unique purposes beyond the concerns of the parties such as “promoting] judicial efficiency and conservation of judicial resources, safeguarding] the accuracy of state court judgments by requiring resolution of constitutional questions while the record is fresh, and lending] finality to state court judgments within a reasonable time.” Acosta v. Artuz, 221 F.3d 117, 123 (2d Cir.2000). Nor is the avenue of amending the proceedings available here as it was-in Day. We know of no rule of procedure or statute that provides this court with a procedural mechanism analogous to Federal Rule of Civil Procedure 15(a) or the statutes governing habeas. See Day, 547 U.S. at 209, 126 S.Ct. 1675; Fed.R.Civ.P. 15(a); 28 U.S.C. § 2243.
[746]*746Federal habeas corpus principles must inform and shape the historic and still vital relation of mutual respect and common purpose existing between the States and the federal courts. In keeping this delicate balance we have been careful to limit the scope of federal intrusion into state criminal adjudications and to safeguard the States’ interest in the integrity of their criminal and collateral proceedings.
[747]*747Thus, the rule set out in Day is tied to the unique balancing that must take place because of the existence of the writ of habeas corpus and the federalism inherent in our constitutional system. While Fed. R.App. P. 4(b) certainly impacts judicial efficiency and contributes to the finality of federal criminal sentences, it does not raise the federalism concerns so crucial in the habeas context. Because the type of interests the AEDPA’s statute of limitations protects are not implicated here, the result in Day is of only marginal relevance to the issue before the court in this case.
B.
No circuit court has directly addressed whether it is appropriate to sua sponte enforce the time limitations of Rule 4(b). When considering Rule 4(b) and other claim-processing rules, courts have generally just proceeded to the merits of the case after the determining the party forfeited its timeliness objection. United States v. Lee, 242 Fed.Appx. 209, 211 (5th Cir.2007) (unpublished) (“[B]eeause the Government did not oppose Lee’s out-of-time appeal, and has thus waived application of Rule 4(b), we may address this case on the merits.”); see also Huerta v. Gonzales, 443 F.3d 753, 756-57 (10th Cir.2006) (holding the Board of Immigration Appeals regulations governing appeals are claim-processing rules and proceeding to the merits after determining the government had forfeited its timeliness objection); First Ave. W. Bldg., LLC v. James (In re Onecast Media, Inc.), 439 F.3d 558, 561 (9th Cir.2006) (raising the timeliness of the defendant’s 59(e) motion sua sponte, but proceeding summarily to the merits after determining Rule 59(e) is claim-processing and the plaintiff forfeited its objection).
In cases where the power of the court to sua sponte enforce a claim-processing rule has been addressed, the results are mixed and do not necessarily apply to the case here. Some courts have interpreted Kontrick and Eberhart as permitting a district court to sua sponte raise a claim-processing rule, but these cases are not instructive because they contain no analysis of the issue and because the procedural posture is sufficiently different from the case before us.10 United States v. Leijano-Cruz, [748]*748473 F.3d 571, 572-73 (5th Cir.2006); United States v. Bryant, 186 Fed.Appx. 298, 299 (3rd Cir.2006) (unpublished); United States v. Fields, 194 Fed.Appx. 825, 826 (11th Cir.2006) (unpublished).
One court of appeals has indicated that it does not have the power to sua sponte enforce a claim-processing rule. Wilburn v. Robinson, 480 F.3d 1140, 1148 n. 12 (D.C.Cir.2007).11 The Wilburn court did not explain the basis for its conclusion, however, beyond rejecting the applicability of Day. Id. Furthermore, the holding was not unequivocal because the court also noted that even if Day did permit it to sua sponte enforce the time bar, it would not choose to do so. Id. Thus, there is almost no guidance on or analysis of the issue before us today from the circuit courts.
C.
Although there is limited authority discussing sua sponte application of the time bars in claim-processing rules, these time bars can be analogized to traditional affirmative defenses. Kontrick indicates such a time bar may be akin to an affirmative defense and therefore must be pleaded by the party benefitting from its application. 540 U.S. at 458-59, 124 S.Ct. 906 (analogizing the time bar in Fed. R. Bankr.P. 4004 to time bars that must be raised pursuant to Fed.R.Civ.P. 8(c)). The comparison is some help in the absence of precedent.
In general, a statute of limitations may not be raised sua sponte and all circuits to consider this issue have held so explicitly. Eriline Co. S.A., 440 F.3d at 658-54; Haskell v. Wash. Twp., 864 F.2d 1266, 1273 (6th Cir.1988); Davis v. Bryan, 810 F.2d 42, 45 (2d Cir.1987); Wagner v. Fawcett Publ’ns, 307 F.2d 409, 412 (7th Cir.1962). Statutes of limitations have traditionally been construed as benefitting the litigants, not the court. For example, “ ‘[sjtatutes of limitations are primarily designed to assure fairness to defendants.’ ” Turgeau v. Admin. Review Bd., 446 F.3d 1052, 1058 (10th Cir.2006) (quoting Burnett v. N.Y. Cent. R.R. Co., 380 U.S. 424, 428, 85 S.Ct. 1050, 13 L.Ed.2d 941 (1965)). Statutes of limitations “ ‘promote justice by preventing surprises through the revival of claims that have been allowed to slumber until evidence has been lost, memories have faded, and witnesses have disappeared.’” Id. (quoting Am. Pipe & [749]*749Const. Co. v. Utah, 414 U.S. 538, 554, 94 S.Ct. 756, 38 L.Ed.2d 713 (1974)).
Although affirmative defenses must usually be pleaded by the party in the first responsive pleading, the Supreme Court has fashioned some exceptions to this general rule. Specifically, the Court has indicated it may be appropriate for a court to raise a preclusion defense sua sponte when “special circumstances” exist. Arizona v. California, 530 U.S. 392, 412, 120 S.Ct. 2304, 147 L.Ed.2d 374 (2000). Res judicata is an affirmative defense which must usually be pleaded by the parties pursuant to Fed.R.Civ.P. 8(c) or it is lost. Id. at 410, 120 S.Ct. 2304; Fed.R.Civ.P. 8(c). In Arizona, the State parties had opportunities to present their preclusion argument at earlier stages in the litigation, but failed to do so. Id. at 409, 120 S.Ct. 2304. Despite this, the State parties urged the Court to raise the preclusion bar sua sponte. Id. at 412, 120 S.Ct. 2304. The Court noted that “[j]udicial initiative of this sort might be appropriate in special circumstances.” Id. It explained “[t]his result is fully consistent with the policies underlying res judicata: it is not based solely on the defendant’s interest in avoiding the burdens of twice defending a suit, but is also based on the avoidance of unnecessary judicial waste.” Id. (quotation omitted).
The Court declined to find special circumstances in that case and thereby significantly narrowed the field of what might constitute “special circumstances.” Id. The State parties in Arizona argued the allegedly precluded issue could have been presented in an earlier proceeding, but deliberately was not. Id. at 407-08, 120 S.Ct. 2304. Thus, there was no contention a court had previously decided the issue presented. Id. at 412, 120 S.Ct. 2304. The Court explained “[w]here no judicial resources have been spent on the resolution of a question, trial courts must be cautious about raising a preclusion bar sua sponte, thereby eroding the principle of party presentation so basic to our system of adjudication.” Id. at 412-13, 120 S.Ct. 2304.
Similarly, in Link v. Wabash R.R. Co., the Supreme Court upheld a district court’s sua sponte dismissal for failure to prosecute. 370 U.S. 626, 630-31, 82 S.Ct. 1386, 8 L.Ed.2d 734 (1962). The Court, noting that courts have always had the power to dismiss for failure to prosecute, explained “[t]he power to invoke this sanction is necessary in order to prevent undue delays in the disposition of pending cases and to avoid congestion in the calendars of the District Courts.” Id. at 629-30, 82 S.Ct. 1386. This authority is an inherent power “governed not by rule or statute but by the control necessarily vested in courts to manage their own affairs so as to achieve the orderly and expeditious disposition of cases.” Id. at 630-31, 82 S.Ct. 1386.
D.
Ours is an adversarial system of justice. The presumption, therefore, is to hold the parties responsible for raising their own defenses. See Eriline Co. S.A., 440 F.3d at 654. A narrow exception may exist, however, when the issue implicates the court’s power to protect its own important institutional interests. See Arizona, 530 U.S. at 412, 120 S.Ct. 2304; Link, 370 U.S. at 629-31, 82 S.Ct. 1386. This principle was at work in Day where the court looked to the important values the habeas scheme was designed to protect and determined they went beyond the interests of the parties. 547 U.S. at 205, 126 S.Ct. 1675. It also underlies Kontrick where, in an initial step in its analysis, the Court examined the purposes of the Bankruptcy Rule at issue and determined the rule [750]*750functioned as an affirmative defense for the debtor.12 540 U.S. at 456, 124 S.Ct. 906. Together, these cases suggest that when a rule implicates judicial interests beyond those of the parties, it may be appropriate for a court to invoke the rule sua sponte in order to protect those interests. See Arizona, 530 U.S. at 412, 120 S.Ct. 2304; Link, 370 U.S. at 629-31, 82 S.Ct. 1386.
This court, therefore, should look to the purposes of Rule 4(b) in addressing sua sponte application. Although they function in much the same way as a statute of limitations, the time bars of the federal rules of procedure are not necessarily for the exclusive benefit of the litigants as are statutes of limitations in civil litigation. Rule 4(b) differs from most time bars, including the time bar in Kontrick, in that it plays an important role in ensuring finality of a criminal conviction. Finality is not solely an interest of the parties to a criminal case. It also serves societal interests and the interests of judicial administration by minimizing uncertainty and waste of judicial resources caused by undue delay. See Day, 547 U.S. at 208, 126 S.Ct. 1675 (pointing to finality of judgment as an important judicial value); Link, 370 U.S. at 629-30, 82 S.Ct. 1386 (noting that calendar congestion and efficiency of judicial administration is a legitimate judicial concern); Arizona, 530 U.S. at 412, 120 S.Ct. 2304 (citing conservation of judicial resources as a justification for sua sponte raising an affirmative defense); United States v. Elliott, 264 F.3d 1171, 1174 (10th Cir.2001) (explaining appeal waivers serve an important function in the judicial administrative process by preserving finality of judgments).
Because Rule 4(b) implicates important judicial interests beyond those of the parties, we hold that this court may raise its time bar sua sponte. This power, however, is limited and should not be invoked when judicial resources and administration are not implicated and the delay has not been inordinate.13 See Arizona, 530 U.S. at 412-13, 120 S.Ct. 2304 (“Where no judicial resources have been spent on the resolution of a question, trial courts must be cautious about raising a preclusion bar sua sponte, thereby eroding the principle of [751]*751party presentation so basic to our system of adjudication.”). Mitchell’s notice of appeal was one day late. This breach of Rule 4(b), however, was not itself the cause of any waste of judicial resources nor did it constitute inordinate delay in appellate claim processing. The record does not indicate any waste of judicial resources were we to reach the merits of Mitchell’s appeal. Nor is there any indication that efficiency of judicial administration or finality are implicated. As a consequence, it would be inappropriate to raise sua sponte the timeliness of Mitchell’s notice of appeal. Accordingly this court proceeds to the merits of the appeal.
IV. Constitutionality of the Search of Mitchell’s Vehicle
“When reviewing an order granting a motion to suppress, we accept the trial court’s factual findings unless clearly erroneous, and we view the evidence in the light most favorable to the district court’s finding.” United States v. Little, 60 F.3d 708, 712 (10th Cir.1995) (quotations omitted). The issue of Fourth Amendment reasonableness, however, is reviewed de novo. Id.
Mitchell argues his arrest was in violation of the Fourth Amendment because, after the initial inspection, the officers had no reasonable suspicion Mitchell had committed an offense. In particular, Mitchell contends the inspection of the inside of the trailer was unlawful because N.M. Stat. Ann. § 65-5-1, which authorizes inspections of commercial trucks, is unconstitutional and thus could not support the regulatory search undertaken in this case.
This court has previously held the commercial trucking industry is a closely regulated industry. United States v. Vasquez-Castillo, 258 F.3d 1207, 1210 (10th Cir.2001). As a result, whether New Mexico’s regulatory scheme is a sufficient substitute for a warrant is determined by the three-part test articulated in New York v. Burger, 482 U.S. 691, 107 S.Ct. 2636, 96 L.Ed.2d 601 (1987). Under Burger, a warrantless inspection made pursuant to a regulatory scheme governing a pervasively regulated business is reasonable if it meets three criteria. Id. at 702, 107 S.Ct. 2636. First, the regulatory scheme must be informed by a substantial government interest. Id. Second, warrantless inspections must be necessary to further the regulatory scheme. Id. at 702-03, 107 S.Ct. 2636. Third, the inspection program must provide a constitutionally adequate substitute for a warrant in terms of the certainty and regularity of its application. Id. at 703, 107 S.Ct. 2636.
Mitchell acknowledges this court has previously considered the constitutionality of the New Mexico regulatory scheme governing commercial carriers and held the statute was constitutional. Vasquez-Castillo, 258 F.3d at 1211-12; see also United States v. Gwathney, 465 F.3d 1133, 1139-40 (10th Cir.2006). He contends, however, that Vasquez-Castillo is distinguishable on its facts and therefore should not be applied here. Mitchell’s contention is incorrect as a matter of law. Vasquez-Castillo analyzed the constitutionality of New Mexico’s regulatory scheme using the three-prong test laid out in Burger and held that the scheme satisfied all three prongs. 258 F.3d at 1211-12. As this court has noted, “the Burger criteria are applied generally to a statutory scheme, not to a given set of facts arising under that scheme.” Gwathney, 465 F.3d at 1140. Under the established precedent of this circuit, the New Mexico statutory scheme meets the requirements of the [752]*752warrant exception set out in Burger.14 See id.; Vasquez-Castillo, 258 F.3d at 1212.
[13] Mitchell also argues the officer’s order to unlock the trailer exceeded the scope of the permissible § 65-5-1 inspections because Mitchell told the officer there was no cargo in the trailer and there was therefore no justification for inspecting the inside of the trailer. The New Mexico statute authorizes inspectors to “inspect the vehicle and its contents to determine whether all laws and all rules and regulations of the departments of this state with respect to public safety, health, welfare and comfort have been fully complied with.” N.M. Stat. Ann. § 65-5-l(F). In addition, the statute provides “[t]he person in charge of the port of entry may satisfy himself as to the contents of the cargo.” Id. § 65-5-l(D). An inspector may also inspect the vehicle’s contents to ensure all excise taxes on fuel, alcohol, or other property have been paid. Id. § 65-5-l(E). This court has held “New Mexico’s regulatory scheme clearly contemplates entrance into the trailer to inspect blocking and bracing, and also allows inspection of the contents of the vehicle.” Gwathney, 465 F.3d at 1139.
There is no meaningful distinction under this statutory scheme between inspection of the contents of a vehicle and inspection of a vehicle to confirm there are no contents. If an operator could escape inspection by giving a verbal statement that the trailer was empty, New Mexico’s ability to conduct meaningful inspections would be seriously compromised. This is particularly true where, as here, the officer has reason to believe the operator has not provided accurate information. New Mexico’s statutory scheme contemplates the inspection of trailers to confirm compliance with New Mexico’s laws and this authorization extends to inspections to confirm an operator’s assertion that he or she carries no cargo. N.M. Stat. Ann. § 65-5-l(F); Gwathney, 465 F.3d at 1140.
Because we hold that the officer’s inspection of the inside of the trailer did not violate the Fourth Amendment, Mitchell’s argument that his consent to examine the contents of the boxes was tainted fails. The district court found, and Mitchell does not directly contest, that he consented to the search of the boxes. Absent any Fourth Amendment violation, this consent was valid and justified a warrantless search. United States v. Jackson, 381 F.3d 984, 988 (10th Cir.2004).
V. Conclusion
The judgment of the district court is AFFIRMED.
