Opinion of the Court by
Wе hold that when an airline passenger consents to a search of his or her effects at an airport security checkpoint, the scope of the search reasonably extends to those receptacles, the contents of which cannot be identified, contained in luggage. We thus affirm the May 14, 2001 decision of the Intermediate Court of Appeals (ICA)
1
reversing the August 26, 1999 order of the district court of the first сircuit (the court) suppressing, as evidence, a gun contained in a bag found in the luggage of Petitioner/Defendant-Appellee William Hanson (Petitioner).
See State v. Hanson,
I.
The court’s findings reflect that on June 11,1999, Petitioner was scheduled to fly from Honolulu, 0‘ahu to Kailua-Kona, Hawaii on Hawaiian Airlines. Petitioner ax-rived at the Hawaiian Airlines ticket counter with a lai'ge amount of luggage including a wooden toolbox. Rredei-ick Gamngei-, a Honolulu Airport secui-ity officex-, 2 examined Petitionei-’s toolbox on an “x-ray” machine but was unable to identify everything within the toolbox. Petitioner allowed Gamnger to seai-ch his toolbox and in fact opened the combination lock on the box. In the box was a tan plastic bag wrapped in duct tape but the bag’s contents could not be identified. Garringer testified that he sought Petitionei-’s permission to searсh the bag; Petitioner claimed othex--wise. As to this matter, the court found Petitionei-’s testimony moi-e credible. Gai--l’inger opened the plastic bag and discovered a second plastic bag containing a white cardboard box. Fi*om the box, Garringer l'ecov-ered a black handgun.
On June 11, 1999, Petitioner was charged with failing to register a firearm, Hawai'i Revised Statutes (HRS) §§ 134-3(a) (1993) and -17(b) (Supp.2000).

On July 9, 1999, Petitioner moved to suppi-ess all еvidence obtained as a i-esult of the search. At a hearing held on August 23, 1999, the motion was orally gi-anted. In its oral decision, the court referred to
State v. Wiley,
In its written conclusions, the court ruled that
a wax-rantless seai-ch of items ... in which a defendant has a legitimate expectation of privacy is presumptively unreasonable....
[[Image here]]
... A search conducted pui-suant to vol-untaiy and uncoerced consent ... is one of the exceptions to the warrant requirement. Such an exception is applicable ... if the right ... is waived....
... [Petitioner] consented to the search of his toolbox....
*73 ... However, under the totality of circumstances ... [Petitioner] did not ... consent to the search of the plastic bag ... [or] voluntarily waive his right to be free from unreasonable searches and seizures.
(Citations and internal quotation marks omitted.)

The ICA vacated the court’s August 26, 1999 findings of fact, conclusions of law, and order, and remanded the case for further proceedings.
See
In arriving at its holding, the ICA: (1) believed that the search did not violate Petitioner’s “reasonable expectation of privacy under the fourth amendment” to the United States Constitution,

op. at 82,
III.
On June 13, 2001, Petitioner filed his application for certiorari. In it, Petitioner contends the ICA: (1) wrongly “overruled” Wiley; 6 (2) violated the rule that “a warrantless search of items, such as a closed, opaque package in which a defendant has a legitimate expectation of privacy, is presumptively unreasonable”; (3) “adopted the rationale that an airline traveler implicitly consents to a limited hand search of luggage’ without any facts in the record ... about prior notice to Hawaii travelers”; (4) cited fedеral and state regulations and state statutes that were not relied upon by the parties below in establishing that “[t]he search of [Petitioner]’s toolbox by Garringer appears to have been pursuant to a screening system adopted by Hawaiian Airlines as mandated by PAA regulation (5) ignored “[t]he court[’s finding] ... that [Petitioner] did not freely and voluntarily consent to the search of the plastic bag found within his toolbox”; and (6) overlоoked “[t]he Hawaii Supreme Court[’s] ... willingness to afford greater protection of individual rights than is provided on the federal level.” In light of Defendant’s objections, we granted certiorari to clarify the basis for upholding airport security searches.
IV.
As to Petitioner’s citation to
Wiley,
we believe that case to be inapposite. Petitioner
*74
apparently relies on the statement in
Wiley
that this court “do[es] not believe that by submitting luggage to an airport screening search, [a defendant] irrevocably relinquished] his [or her] constitutional right to be free from unreasonable searches that fall outside the limited scope of such a screening.”
[O]nce a defendant is placed under arrest, and his [or her] belongings relinquished to police control, the justification for an airport security search cannot be used to circumvent the well-established constitutional protections of search and seizure law.
[[Image here]]
... [Thus, o]nce [the defendant was placed under arrest, and his belongings placed under the complete control of law enforcement officers, any further search was required to meet the constitutional provisions of the warrant requirement or fall within onе of its exceptions. Therefore, the circuit court’s order suppressing the use of contraband recovered from the search of the pillow as evidence is affirmed.
Id. Contrastingly, Petitioner was not under arrest at the time of the search and had consented to the search. See discussion in section V, infra.
As Petitioner points out in connection with his second point, this court has held that a warrantless search of a closed oрaque package in which a defendant has a legitimate expectation of privacy is presumptively unreasonable.
See State v. Wallace,
As to a part of his third point, we cannot accept Petitioner’s contention that there was a lack of any “facts in the record below about *75 prior notice to Hawaii’s travelers” that they would be subject to searches. The security procedures conditioning entry to bоarding areas and examination of baggage, evident in the record, would have provided prior notice that Petitioner’s baggage was subject to search, and Petitioner does not contend otherwise.
In regard to his fourth argument, Petitioner is correct in asserting that the Federal Aviation Administration regulations pertaining to security and screening procedures at airports were not a part of the rеcord. However, these matters were cited by the ICA for the proposition that “Gamnger’s search of [Petitioner's toolbox [is a] governmental search for purposes of article I, [section] 7 of the Hayvai'i Constitution, as well as the fourth amendment.” Op. at 81,
V.
We discuss the crux of Petitioner’s third contention with his fifth one because of their relatedness. It is not disputed that Petitioner voluntarily surrendered his toolbox to inspection. Having done so, he consented to the search of the toolbox. Consent may also be implied “from an individual’s words, gestures, or conduct.”
United States v. Buettner-Janusch,
Such implied consent may also be imputed from the nature of airport security measures.
See Pulido-Baquerizo,
(holding that “those passengers placing luggage on an x-ray machine’s conveyor belt for airplane travel at a secured boarding area impliedly consent to a visual inspection and limited hand search of them luggage if the x-ray scan is inconclusive in determining whether the luggage contains weapons or other dangerous objects.”);
Shapiro v. State,
*76
As the court determined, consent is an exception to and dispenses with the requirement of a warrant.
See, e.g., Schneckloth v. Bustamonte,
Petitioner’s contention, however, is that in the absence of his “voluntary and uncoerced consent,” a warrant was required for a further search of the containers within the toolbox. That contention implicates the reasonable scope of the search to whiсh consent had been given. Plainly, the surrender of one’s effects at airport security checkpoints is to allow inspection of such effects for contents that may pose a danger to those on the aircraft. The inspection of surrendered effects amounts to a search.
See Terry v. Ohio,
Because the purpose of a security inspection can only be effectuated if the items subject to search can be identified, searches of such belongings must reasonably extend to those containers whose contents cannot be discerned. Accordingly, on facts similar to the instant case, courts hаve treated the search of receptacles as falling within the scope of a luggage search. In
Santiago v. State,
[s]ince the detection of ... deadly, but easily concealable, substances is the very rationale for the search to begin with— that which makes ... the initial intrusion reasonable—it necessarily follows that the search may properly continue into packages and containers, such as the box in *77 question, winch cannot otherwise be clearly identified as harmless.
Id. at 502-03 (emphasis added).
Considering its purpose, the scope of the airport checkpoint security search may reasonably extend to the indiscernible contents of any containers in luggage. The reach of such a search is reasonably tailored to protect against “the magnitude and pervasiveness of the danger” to aircraft occupants that is the governmental objective of airport searches.

For the foregoing reasons, we affirm the ICA’s May 14, 2001 opinion vacating the district court’s August 26, 1999 “Findings of Fact, Conclusions of Law and Order Granting Defendant Hanson’s Motion to Suppress Evidence, Filed July 9, 1999” and remanding the ease to the court.
Notes
. Associate Judge Daniel R. Foley authored the opinion of the ICA, and was joined by Chief Judge James S. Burns and Associate Judge John S.W. Lim.
. Garringer was employed by International Total Sen/ice (ITS), a security company. Garringer was unaware of whether ITS had a security contract with the airport or with Hawaiian Airlines. In any event, Respondent/Plaintiff-Appellant Slate of Hawaii does not contend that Gar-ringer was working other than as an agent of the government at the time he searched Petitioner’s toolbox.
. HRS § 134-3(a) (Supp.2000) reads, "[e]very person arriving in the State who brings or by any other manner causes to be brought into the State a firearm of any description ... shall register the firearm within three days after arrival of the person or of the firearm!..]” HRS § 134-17(b) (Supp.2000) explains that "[a]ny person who violates section 134-3(a) shall be guilty of a petty misdemeanor.”
. The fourth amendment to the United States Constitution states:
The right of the people to be sеcure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
. Article I, section 7 of the Hawaii Constitution states:
The right of the people to be secure in their persons, houses, papers and effects against unreasonable searches, seizures and invasions of privacy shall nol be violated; and no warrants shall issue but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched and the persons or things to be seized or the communications sought to be intercepted.
.Petitioner also maintains "even if the ICA did not implicitly ovеrrule Wiley, its failure to at least cite to it raises a clear inference that it inadvertently overlooked Wiley.”
. Also, airport searches of passengers' belongings are arguably less scandalous and embarrassing than other police searches because (1) the owner of the luggage searched must "voluntarily come to and enter the search area" and (2) the frequency of such searches makеs the individual whose bags are examined feel that there is less of a stigma attached to the search.
See United States v. Skipwith,
. This court and other jurisdictions have applied implied consent analysis to other situations where public policy demands heightened security.
See State v. Martinez,
. California and the Ninth Circuit have determined that airport searches are "administrative searches.” According to the California Supreme Court,
searches conducted as part of a general regulatory scheme in furtherance of an administrative purpose, rather than as part of a criminal investigation to secure evidence of crime, may be permissible under the Fourth Amendment though not supported by a showing of probable cause directed to a particular place or person to be searched.
