ZINTER, Justice.
[¶ 1.] Touray Akuba and Kaisha Paul were stopped by a highway patrol officer for speeding. Akuba allegedly consented to a search of the vehicle. During the search, the officer found 177 pounds of marijuana in the trunk. Akuba and Paul moved to suppress, alleging that they were illegally detained and the consent was involuntary. The trial court suppressed. The State now appeals arguing that the detention was legal, that Akuba voluntarily consented to the search, and that Paul had no standing to challenge it. We conclude that the detention was lawful and the consent to search was valid, and therefore, even if Paul had standing to challenge Akuba’s consent, the evidence should not have been suppressed. We reverse.
Facts and Procedural History
[¶ 2.] On September 2, 2002, highway patrol officer Matt Oxner was patrolling Interstate 90, east of Rapid City. Oxner was a canine officer focused on drug interdiction. While traveling west, Oxner observed a vehicle traveling east through a construction zone. Because the vehicle appeared to be catching up with vehicles in front of it, Oxner activated his radar and determined that the vehicle was traveling 68 mph in a 65 mph construction zone. Oxner turned around, pursued the vehicle, and followed it for approximately two miles. Oxner also requested a license plate check to determine if the vehicle was stolen. A radio dispatcher informed Ox-ner that the vehicle was a rental car from Oregon.
[¶ 3.] Oxner activated his lights and stopped the vehicle. Akuba was driving and Paul (Akuba’s brother’s girlfriend) was in the front passenger seat. Oxner observed an atlas, blankets, pillows, and food containers in the vehicle, which indicated to him that they were driving without stopping overnight.
[410]*410[¶ 4.] Oxner informed Akuba that Ox-ner had stopped the car to warn Akuba of the speeding violation. Oxner obtained Akuba’s driver’s license and the car rental agreement. While at the car, Oxner noticed no evidence of marijuana or other illegal substances. He informed Akuba that he was going to give him a warning ticket for the speeding violation, and he asked Akuba to accompany him back to the patrol car to issue the ticket.
[¶ 5.] Upon entering the patrol car, Ox-ner began writing the warning ticket. In that process, Oxner engaged Akuba in routine traffic stop questioning. He first asked their destination. Akuba told Oxner that they were traveling from Seattle to Chicago. They then engaged in a casual conversation concerning the purpose of the trip to Chicago, where the car was rented from, and where Akuba worked. Akuba told Oxner they were going to Chicago to meet his brother. Akuba also indicated that they were driving straight through and intended to stay for a couple of days. He finally told Oxner that he worked at a business in Seattle.
[¶ 6.] Oxner then reiterated that he was only going to give Akuba a warning for the speeding violation, but Oxner also told Akuba that he was going to check his driver’s license. In the course of that short conversation, they not only discussed the driver’s license check, but Oxner also mentioned a drug dog sniff, and he requested consent to search the car. Akuba consented on two occasions. The transcript reveals those consents were given during the scope of the initial stop to issue the warning ticket and check Akuba’s driver’s license.
OFFICER: Everything’s okay with your license?
AKUBA: Yep.
OFFICER: Okay. Have you ever been in trouble before at all?
AKUBA: No.
OFFICER: Okay. Then what I normally do, Touray, being a canine officer— AKUBA: Uh-hum.
OFFICER: — okay, I got a drug dog in the back, and what I normally do is walk him around most vehicles that I have stopped checking for all illegal — the different o[dors] of illegal drugs, marijuana—
AKUBA: Um-hum.
OFFICER: — cocaine, methamphet-
amine, heroin—
AKUBA: Yeah.
OFFICER: — anything like that. Any prescription drugs, anything like that. So I’m going to go ahead and walk him around the car. Do you think he’s going to smell anything from the car?
AKUBA: Nothing. Nothing.
OFFICER: Nothing. Okay. Is it okay if I look in the car?
AKUBA: Yeah.
OFFICER: I can look?
AKUBA: Um-hum.
OFFICER: Okay.
Oxner noticed that Akuba’s nervousness increased at the mention of the drug dog.1 After further brief conversation before the driver’s license check came back from the dispatcher, Oxner confirmed that Akuba had consented to a search stating: “So you’ll go ahead and let me look in the ear then, Touray?” Akuba consented a third time, replying, “Um-hum.”
[¶ 7.] While still waiting for the driver’s license check to return from the dispatch[411]*411er, they continued their conversation about Akuba’s employment, the warning ticket, and the search of the vehicle:
OFFICER: So what kind of business do you work at? An African business? AKUBA: African business, yeah. OFFICER: What’s that?
AKUBA: African clothes.
OFFICER: Clothes?
AKUBA: (No response could be heard....)
OFFICER: Is it your store or somebody else’s?
AKUBA: Ah, my brother and his partner.
OFFICER: Brother’s store?
AKUBA: (No response could be heard....)
OFFICER: Here’s your license ... back, Touray. Here’s just a warning for the speed. You don’t have to do nothing with the warning. You can throw that away. Just watch your speed a little closer when you go into those zones, okay?
AKUBA: (No response could be heard....)
OFFICER: Then when this [driver’s license] comes back you’ll be free to go. If you let me look real quick—
AKUBA: Um-hum.
OFFICER: — we’ll do that—
AKUBA: Um-hum.
OFFICER: — get you going here....
When the driver’s license check subsequently came back, Oxner told the radio dispatcher that he “had a vehicle for a search.” He also stated to Akuba, “Okay, you guys will be free to go if you let me search real quick. I’ll just have you stand in front of the car, okay?” Akuba again replied, ‘Yeah.”2
[¶ 8.] Oxner and Akuba then got out of the patrol car and approached the rental car. Oxner did not take the drug dog with him. Upon approaching the car, Oxner confirmed to Paul that “Touray is going to let me look in the vehicle real quick and we’ll get you guys going.” Oxner then asked Paul and Akuba to stand near the front of the car. Akuba and Paul stood silently without objection while Oxner searched the vehicle. Oxner first looked in the front passenger side of the car. He then unlocked the doors and searched the back seat. After searching the interior of the car for about two minutes, Oxner took the keys from the ignition and searched the trunk. Oxner found four large duffel bags containing 177 pounds of marijuana. The entire stop, including the search, took approximately ten minutes.
[¶ 9.] Akuba and Paul were placed under arrest and later interviewed by an agent of the Division of Criminal Investigation. Akuba admitted that he knew the marijuana was in the trunk and that he [412]*412was paid $1,000 to transport it to Chicago. Akuba and Paul were subsequently-charged with possession of marijuana, more than ten pounds, in violation of SDCL 22-42-6.
[¶ 10.] After pre-trial hearings, the trial court granted Akuba’s motion to suppress. The court ruled that the State failed to prove that Akuba had voluntarily consented to the search. The court arrived at that conclusion by reasoning that Oxner improperly expanded the scope of the stop by engaging in “impermissibly intrusive” questioning beyond the scope of a routine traffic stop. The court held that asking for Akuba’s consent to search the vehicle, when the officer had no reasonable suspicion to do so, was impermissibly intrusive questioning that resulted in an illegal detention. The court ultimately concluded that the illegal detention, coupled with a “threat”3 to use the drug dog, coerced Akuba’s consent and rendered it involuntary as a matter of law. In Paul’s related motion, the trial court suppressed, concluding that the evidence was the fruit of an illegal detention. The trial court declined to address Paul’s standing to object to the search.
[¶ 11.] The State raises the following issues on appeal:
1. Whether the State’s burden of proving voluntary consent should be by a “preponderance of the evidence” or by “clear and convincing evidence.”
2. Whether the warrantless search of the vehicle was authorized by Aku-ba’s consent.
3. Whether Paul, having failed to make any showing that she possessed a legitimate expectation of privacy in the trunk of the rental vehicle, had standing to challenge the search.
Analysis and Decision
1. Whether the State’s burden of proving voluntary consent should be by a “preponderance of the evidence” or by “clear and convincing evidence.”
[¶ 12.] “Even when police officers have neither probable cause nor a warrant, they may search an area if they obtain a voluntary consent from someone possessing adequate authority over the area.” United States v. Chaidez, 906 F.2d 877, 380 (8thCir.1990) (citing United States v. Matlock, 415 U.S. 164, 171 n. 7, 94 S.Ct. 988, 993 n. 7, 39 L.Ed.2d 242 (1974)). “It has been said that consent to conduct a search satisfies the Fourth Amendment, thereby removing the need for a warrant or even probable cause.” State v. Sheehy, 2001 SD 130, ¶ 11, 636 N.W.2d 451, 453 (citations omitted). “For consent to a search to be valid, the totality of the circumstances must indicate that it was voluntarily given.” State v. Almond, 511 N.W.2d 572, 573 (S.D.1994) (citations omitted).
[¶ 13.] We have previously required that “[t]he State must establish vol-untariness by clear and convincing evidence!].]” State v. Zachodni, 466 N.W.2d 624, 629 (S.D.1991) (citations omitted). However, most courts no longer require clear and convincing evidence. Today we conform our burden of proof to that used by the United States Supreme Court and the Eighth Circuit Court of Appeals.4 They hold that “[i]n deciding whether a consent was voluntary, courts should require the prosecution to prove voluntariness by a preponderance of the evidence.” Chaidez, 906 F.2d at 380 (citing Matlock, [413]*413415 U.S. at 177, 94 S.Ct. 988). Numerous other courts also apply the preponderance burden of proof.5 We finally note that the preponderance burden is consistent with the burden we have applied in the closely related issue of the voluntariness of a confession. See State v. Tuttle, 2002 SD 94, ¶ 21, 650 N.W.2d 20, 30-31. We now hold that the preponderance burden should be applied when considering the voluntariness of a consent to search.6
2. Whether the warrantless search of the vehicle was authorized by Akuba’s consent.
Legality of the Stop
[¶ 14.] As a preliminary matter, Akuba questions the legality of the stop. He asserts that Oxner did not stop him for speeding. Akuba argues that the testimony regarding “the alleged speeding violation” shows that “there may well have been no such violation.” Akuba suggests that Oxner stopped the car merely because Akuba was an African American in an out-of-state vehicle.
[¶ 15.] However, after reviewing the videotape of the stop, we agree that Akuba’s suggestion has no merit. As the trial court specifically stated in its memorandum opinion, there was an objective basis for the stop of Akuba’s vehicle, i.e., its speed of 68 mph in a 65 mph zone. This speeding offense warranted the stop because a traffic violation is an objectively reasonable basis to stop a vehicle.
While the stop may not be the product .of mere whim, caprice or idle curiosity, it is enough that the stop is based upon “specific and articulable facts which taken together with rational inferences from those facts, reasonably warrant [the] intrusion.” State v. Herrboldt, 1999 SD 55, ¶ 7, 593 N.W.2d 805, 808 (quoting Spenner v. City of Sioux Falls, 1998 SD 56, ¶ 14, 580 N.W.2d 606, 611). Under these standards, it is well established that a traffic violation, however minor, creates sufficient cause to stop the driver of a vehicle.” Whren v. United States, 517 U.S. 806, 810, 116 S.Ct. 1769,1772,135 L.Ed.2d 89, 95-95 (1996); State v. Kenyon, 2002 SD 111, ¶ 16, 651 N.W.2d 269, 274. ■
State v. Chavez, 2003 SD 93, ¶ 16, 668 N.W.2d 89, 95 (emphasis added).
[¶ 16.] Although the State agrees that the trial court “expressed displeasure with the manner in which the stop was made,” and although Akuba hints that Ox-[414]*414ner may have had other subjective reasons for stopping the vehicle, other subjective intent or motivation does not invalidate a stop:
[BJecause [the officer] was legally authorized to stop the vehicle, any additional “underlying intent or motivation” would not have invalidated the stop. United States v. Bloomfield, 40 F.3d 910, 915 (8thCir.1994), cert. denied, 514 U.S. 1113, 115 S.Ct. 1970, 131 L.Ed.2d 859 (1995); United States v. Cummins, 920 F.2d 498, 501 (8thCir.1990). Even if [the officer] had other motivations to stop [the vehicle], those subjective reasons were not relevant. They were not relevant because this stop was objectively reasonable, and an objectively reasonable stop is not invalidated even if the stop was pretextual. State v. Lamont, 2001 SD 92, ¶ 21, 631 N.W.2d 603, 610 (citing Arkansas v. Sullivan, 532 U.S. 769, 772, 121 S.Ct. 1876, 1878, 149 L.Ed.2d 994, 998 (2001)).
Id. ¶ 20, 631 N.W.2d 603.7 Moreover, the fact that Akuba’s speeding was a marginal violation is of no consequence. “An officer’s observation of a traffic violation, however minor, gives the officer probable cause to stop a vehicle, even if the officer would have ignored the violation but for a suspicion that greater crimes are afoot.” United States v. Luna, 368 F.3d 876, 878 (8thCir.2004) (citing United States v. Martinez, 358 F.3d 1005, 1009 (8thCir.2004)). As the Eighth Circuit recently noted in a case upholding a traffic stop for “expired tags” notwithstanding an allegation of racial profiling: “The United States Supreme Court holds that a traffic stop is constitutional, no matter the officer’s subjective intent, so long as the officer had probable cause to believe that a traffic violation occurred.” United States v. Gomez Serena, 368 F.3d 1037, 1041 (8thCir.2004) (citing Whren v. United States, 517 U.S. 806, 813, 116 S.Ct. 1769, 135 L.Ed.2d 89 (1996)).
Consent to Search
[¶ 17.] The trial court’s memorandum opinion reveals that its ruling was based on the legal notion that by asking for consent to search, Oxner impermissibly extended the stop beyond the permissible scope of a traffic stop. Relying on United States v. Ramos, 42 F.3d 1160 (8thCir.1994), the trial court reasoned that because there was no reasonable suspicion to expand the traffic stop, the request for consent occurred during an illegal detention. The court concluded that because consent was requested during an illegal detention, the consent was involuntary as a matter of law. However, the trial court’s application of Ramos to this case is misplaced.
[¶ 18.] Ramos is distinguishable on its facts. Ramos involved an impermissible detention of the occupants of a vehicle beyond the time necessary for the intrusion associated with the traffic stop. It also involved a request for consent to search within that illegal detention: the consent was requested after the vehicle’s occupants’ licenses and registration had been checked and cleared. Here, however, Akuba was still in the officer’s car waiting for his warning ticket and license check to be completed when he consented to the search. In fact, only three minutes expired from the time Akuba entered the patrol car until Oxner first asked for consent to search. Therefore, unlike Ramos, [415]*415this request for consent occurred during the scope of a valid traffic stop, and any consent obtained during that lawful detention was valid.
[¶ 19.] Akuba, however, argues that Oxner’s detention and request for consent was an “arbitrary interference” and an unreasonable “government intrusion on the roadways.” We disagree. Akuba and Paul were stopped for speeding, and the traffic portion of the stop did not extend beyond that necessary to complete the warning ticket and license check.8 Moreover, the questioning that occurred while they were waiting for the license check did not create an illegal detention.
[¶ 20.] An officer does not im-permissibly expand the scope of a traffic stop merely by asking the driver questions, even if the subject of the questioning is unrelated to the original purpose of the stop, as long as the questioning does not unduly extend the duration of the initial, valid seizure. Ramos, 42 F.3d at 1165 (Beam, J., concurring); United States v. Shabazz, 993 F.2d 431, 436 (5thCir.1993); United States v. Purcell, 236 F.3d 1274, 1279-80 (11thCir.2001); State v. Parkinson, 135 Idaho 357, 17 P.3d 301, 307 (2000). After all, “mere questioning ... is neither a search nor a seizure.” Shabazz, 993 F.2d at 436 (citing Florida v. Bostick, 501 U.S. 429, 434, 111 S.Ct. 2382, 2386, 115 L.Ed.2d 389 (1991)). In fact, Ramos itself permitted such questioning on subjects like place of origination, destination, employment and the purpose of the trip. Ramos, 42 F.3d at 1161. “Typically, a reasonable investigation of a traffic stop may include asking for the driver’s license and registration, requesting the driver to sit in the patrol car, and asking the driver about his destination and purpose.” Id. at 1163 (citations omitted). That type of questioning is reasonable and not an arbitrary interference.
[¶ 21.] Moreover, Oxner’s request for Akuba’s consent to search before the traffic stop was completed did not render the stop an impermissible detention. In Almond, we quoted Bostick, 501 U.S. at 434-35, 111 S.Ct. at 2386, 115 L.Ed.2d at 398-99: “Even when officers have no basis for suspecting a particular individual, they may generally ask questions of that individual, ask to examine the individual’s identification, and request to search his or her luggage [.] ” 511 N.W.2d at 575 (emphasis added). So also, in State v. Dreps, 1996 SD 142, 558 N.W.2d 339, an officer conceded that he had no articulable suspicion when he asked the defendant whether he had any illegal weapons, drugs, or contraband. Nevertheless, we held that “an officer does not have to have probable cause to search before requesting consent to search.” Id. at ¶ 11, 558 N.W.2d 339.
[¶ 22.] We have arrived at these conclusions because questioning, including a request for consent to search, during the course of a lawful traffic stop, need not be related to the reason for that stop. “[Because [such] questions are neither searches nor seizures, police need not demonstrate justification for each inquiry” as is otherwise necessary under Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889. U.S. v. Childs, 277 F.3d 947, 949 (7thCir.2002). As the Seventh Circuit explained:
Under the fourth amendment, every search or seizure must be “reasonable,” [416]*416which normally entails some person-specific basis for suspicion. See Indianapolis v. Edmond, 531 U.S. 32, 121 S.Ct. 447, 148 L.Ed.2d 333 (2000). But the Supreme Court has held repeatedly that police may approach persons and ask questions or seek their permission to search, provided that the officers do not imply that answers or consent are obligatory. See, e.g., Florida v. Rodriguez, 469 U.S. 1, 5-6, 105 S.Ct. 308, 83 L.Ed.2d 165 (1984); INS v. Delgado, 466 U.S. 210, 104 S.Ct. 1758, 80 L.Ed.2d 247 (1984); Florida v. Royer, 460 U.S. 491, 501, 103 S.Ct. 1319, 75 L.Ed.2d 229 (1983) (plurality opinion); United States v. Mendenhall, 446 U.S. 544, 552-58, 100 S.Ct. 1870, 64 L.Ed.2d 497 (1980). These requests are proper without regard to the absence of reasonable suspicion, the Court made clear in Florida v. Bostick, 501 U.S. 429, 434, 111 S.Ct. 2382, 115 L.Ed.2d 389 (1991), because “mere police questioning does not constitute a seizure.”
Id. at 950 (emphasis added). See also, Shabazz, 993 F.2d 431 (holding that questions and request for consent to search four minutes into a traffic stop were not a “seizure,” and thus did not require predicate probable cause or reasonable suspicion); U.S. v. Burton, 334 F.3d 514, 518 (6thCir.2003) (holding police could, during the course of a traffic stop, ask driver whether he would consent to a search of the automobile); People v. Moore, 341 Ill. App.3d 804, 275 Ill.Dec. 361, 792 N.E.2d 836, 843-844 (2003) (brief questioning, during traffic stop, about contraband and request for consent to search vehicle was legal, and reasonable suspicion was unnecessary); State v. Harris, 590 N.W.2d 90, 102 (Minn.1999) (noting (1) that generally, questioning in a vehicle stop is not a seizure, and (2) absent a seizure within the meaning of the Constitution, the reasonable suspicion inquiry is unnecessary); State v. Middleton, 43 S.W.3d 881 (Mo.Ct.App.2001) (permitting an officer, while writing a motorist a speeding ticket, to ask for consent to search for drugs because an officer may ask for consent to search in the absence of reasonable suspicion or probable cause); State v. Everson, 474 N.W.2d 695 (N.D.1991) (holding that an officer was not required to have reasonable suspicion of drug activity before requesting consent to search during a license check conducted in the course of a traffic stop); State v. Boatman, 185 Or.App. 27, 57 P.3d 918 (2002) (holding that before necessary paperwork associated with traffic stop was completed, officer could request consent to search even though it was unrelated to the traffic stop and there was no reasonable suspicion that the defendant has engaged in criminal activity); James v. State, 102 S.W.3d 162 (Tex.App.2003) (permitting an officer, after giving a warning ticket for minor traffic offenses, to request consent to search because reasonable suspicion to continue detention and search is not required for valid consent following resolution of original reason for stop); 3 LaFave Search and Seizure § 8.1 (3d ed 1996).
[¶ 23.] The dissent cites no contrary authority,9 but instead relates its displea[417]*417sure with police investigative techniques. However, the dissent’s concerns have been considered and rejected by other courts.
What happened here must occur thousands of times daily across the nation: Officers ask persons stopped for traffic offenses whether they are committing any other crimes. That is not an unreasonable law-enforcement strategy, either in a given case or in gross; persons who do not like the question can decline to answer. Unlike many other methods of enforcing the criminal law, this respects everyone’s privacy. There is therefore no reason to doubt the validity of [the driver’s] consent....
Childs, 277 F.3d at 954.
[¶ 24.] We therefore conclude that the trial court erred in requiring the officer to possess some quantum of suspicion of criminal activity before requesting consent to search. Reasonable suspicion is simply not required in this Fourth Amendment context. An officer need not have reasonable suspicion that a vehicle contains contraband before asking to search it. Here, because the initial traffic stop was not completed when the consent was requested, the scope of the stop was not imper-missibly extended. And, because Oxner’s request for consent to search was made within the period of the initial lawful detention, Akuba’s consent was not involuntary as a matter of law. State v. Ballard, 2000 SD 134, 617 N.W.2d 837.
The Factual Issue of Consent
[¶ 25.] Having determined that there was no legal reason to invalidate Akuba’s consent, the next issue is whether Akuba actually consented to a search of the vehicle. The State bears the burden of proving, under the totality of the circumstances, that valid consent to search was given. Sheehy, 2001 SD 130, ¶ 11, 636 N.W.2d at 453^154 (citing Almond, 511 N.W.2d at 573). Whether a valid consent to search exists is generally a question of fact for the trial court. Id. “Because the presence or absence of consent to search is a question of fact, the trial court’s resolution of that question will be upheld unless our examination of the evidence, construed in a light most favorable to the trial court’s findings, convinces us that the finding was clearly erroneous.” Almond, 511 N.W.2d at 573.
[¶ 26.] In this case, however, the trial court only made conclusions of law or mixed findings of fact and conclusions of law on this issue. We have no findings of historical fact to which the clearly errone[418]*418ous standard applies. Therefore, our task involves an application of the facts to the law, and that review is de novo. Sheehy, 2001 SD 130, ¶ 6, 636 N.W.2d at 452. De novo review is also appropriate .because there was no dispute of fact about this issue. Akuba did not testify that he was coerced or otherwise failed to give consent. The only live witness on this issue was Oxner, and he was only asked one question on this subject: he said there was consent. The only other record evidence is the videotape, and “because we had the same opportunity to review the videotape ... as the trial court,” we review the issue of Akuba’s consent de novo. Tuttle, 2002 SD 94, ¶ 29 n. 11, 650 N.W.2d at 35 n. 11.
[¶ 27.] Based upon our review of the videotape, we believe that Akuba gave three voluntary and unconditional consents to search within the first five minutes of the encounter. The video (and especially the audio portion) clearly reflect that Aku-ba voluntarily consented the first three times he was asked. Moreover, these consents were given after only brief questioning, Akuba was not under arrest, he was on a public interstate during daylight, and the dog in the car was not barking. “Because even persons who have been arrested and are in custody can voluntarily consent to a search ... we do not believe that the setting for [Akuba’s] consent was unduly coercive.” Chaidez, 906 F.2d at 382 (citing United States v. Watson, 423 U.S. 411, 424, 96 S.Ct. 820, 828, 46 L.Ed.2d 598, 609 (1976)).
[¶ 28.] Akuba, however, argues that exchanges four and five, as they appear in a unitten transcript, could be interpreted as impermissible demands to search that were the conditions for Akuba’s release. To facilitate a review of this assertion, we have repeated all six exchanges in the written transcript in chronological order, but removed from their contextual ties, (for the full context see supra ¶¶ 5-8):
(1) OFFICER: Is it okay if I look in the car?
AKUBA: Yeah.
(2) OFFICER: I can look?
AKUBA: Um-hum.
(3) OFFICER: So you’ll go ahead and let me look in the car then, Touray?
AKUBA: Um-hum.
(4) OFFICER: Then when [the license check] comes back you’ll be free to go. If you let me look real quick—
AKUBA: Um-hum.
OFFICER: — we’ll do that—
AKUBA: Um-hum.
OFFICER: — get you going here.
(5) OFFICER: Okay, you guys will be free to go if you let me search real quick....
AKUBA: Yeah.10
(6) OFFICER: Touray is going to let me look in the vehicle real quick and we’ll get you guys going.
[¶ 29.] We first observe that the audio evidence of these exchanges reflects that three consents were obtained before the alleged “conditional” requests were made. Akuba clearly consented three times in the first five minutes of an entire stop and search that only lasted ten minutes. More importantly, the tone, pausing, and context of the officer’s language in exchanges four and five reflect that they were not further requests for consent, but rather, were casual conversation executing the consent previously given. Although exchanges four and five were susceptible to interpre[419]*419tation based solely upon a transcript, the actual audio reflects that they were conversational in tone and appear to merely have been made to keep Akuba informed of the process Oxner was going to follow after Akuba’s consent to search. We also note that the one reference to the drug dog was not objectively coercive. The dog was in the canine officer’s vehicle, and we see nothing coercive per se in disclosing the historically correct fact that this canine officer usually conducts drug sniffs around the exterior of lawfully stopped vehicles. We finally note that the officer’s response to the radio dispatcher after exchange four (he had a vehicle for a search) reflects the officer’s contemporaneous belief that he had already obtained consent to search. Therefore, we do not find that exchanges four and five demonstrate that the consent was conditional.
[¶ 30.] We again acknowledge that the historical question of consent to search is a question of fact. Furthermore, as an appellate court, we are bound to uphold a trial court’s resolution of questions of fact unless the evidence convinces us that the trial court was clearly erroneous. Almond, 511 N.W.2d at 573. However, as previously discussed, the trial court’s findings on consent were erroneously premised on incorrect legal conclusions that the officer impermissibly expanded the stop and that the consent obtained during that illegal detention was involuntary as a matter of law. We are not bound by such legal conclusions. Therefore, based on our de novo review of the audio evidence, we determine that Akuba’s consent was voluntary.
[¶ 31.] We finally note that Oxner did not exceed the scope of Aku-ba’s consent by searching the trunk. “The standard for measuring the scope of a suspect’s consent under the Fourth Amendment is that of ‘objective’ reasonableness — what would the typical reasonable person have understood by the exchange between the officer and the suspect?” Florida v. Jimeno, 500 U.S. 248, 251, 111 S.Ct. 1801, 1803-1804, 114 L.Ed.2d 297, 302 (1991) (citations omitted). In Jimeno, the driver of a car told police that they could search the car. During the search, the officer opened a folded, brown paper bag on the floorboard of the car. The driver later argued that he had only meant to consent to a search of the visible interi- or of the vehicle, and not closed containers within it. The Supreme Court first noted that the consent was not limited in its scope. The Court then noted that the consent came after the officer had informed the driver that he believed the driver was carrying narcotics, and that “the scope of a search is generally defined by its expressed object.” Id. Under those circumstances, the Supreme Court held that it was objectively reasonable for the officer to assume that the driver’s general consent authorized a search of any items within the car that might contain drugs. Id. at 251, 111 S.Ct. 1801. See also United States v. Pena, 920 F.2d 1509 (10thCir.l990) (consent to search for drugs in car authorized tapping of external fender and probing of rear door panel after officer observed loose, crooked and missing screws); United States v. Lechuga, 925 F.2d 1035 (7thCir.l991) (consent to search for drugs in apartment authorized search of suitcase in closet); see also Charles H. Whitebread & Christopher Slobogin, Criminal Procedure: An Analysis of Cases and Concepts § 12.03 (4th ed 2000).
[¶ 32.] Here, Akuba gave a general consent to search for drugs, he did not subsequently limit this consent, and he [420]*420stood silently without objection while Ox-ner opened the trunk and duffel bags. Under these circumstances, it was objectively reasonable for the officer to assume that Akuba’s consent to search for drugs included a search of any area that could contain drugs, which included the trunk of the vehicle.
[¶ 83.] It was also objectively reasonable to search the duffel bags in the trunk. As the Second Circuit Court of Appeals stated:
It is self-evident that a police officer seeking general permission to search a vehicle is looking for evidence of illegal activity. It is just as obvious that such evidence might be hidden in closed containers. If the consent to search is entirely open-ended, a reasonable person would have no cause to believe that the search will be limited in some way.
United States v. Snow, 44 F.3d 133, 135 (2d Cir.1995). Or, as the United States Supreme Court has noted:
A suspect may of course delimit as he chooses the scope of the search to which he consents. But if his consent would reasonably be understood to extend to a particular container, the Fourth Amendment provides no grounds for requiring a more explicit authorization.
Jimeno, 500 U.S. at 252, 111 S.Ct. at 1804, 114 L.Ed.2d at 303. We therefore conclude that when viewed objectively, Oxner did not exceed the scope of Akuba’s consent when he searched the duffel bags in the trunk of the rental car.
3. Whether Paul, having failed to make any showing that she possessed a legitimate expectation of privacy in the trunk of the rental vehicle, had standing to challenge the search.
[¶ 34.] After the trial court entered its memorandum opinion suppressing the evidence against Akuba, Paul filed a motion to join Akuba’s suppression motion. The State filed a brief opposing Paul’s motion. The State acknowledged that Paul had standing to challenge the initial traffic stop because a stop is a seizure of all persons in a vehicle. State v. Krebs, 504 N.W.2d 580, 584 (S.D.1993) (citing United States v. Erwin, 875 F.2d 268, 270 (10th Cir.1989)). Consequently, Paul had standing to challenge the legality of her own detention. United States v. Ameling, 328 F.3d 443, 446 n. 3 (8th Cir.2003) (citing United States v. Lyton, 161 F.3d 1168, 1170 (8th Cir.1998)). However, the State argued that Paul did not have standing to challenge Akuba’s consent to search the trunk of the car. The State continues that argument, asserting that Paul lacks standing to challenge the search of the trunk because “Fourth Amendment rights are personal rights which ... may not be vicariously asserted.” Krebs, 504 N.W.2d at 586 (quoting Rakas v. Illinois, 439 U.S. 128, 133-34, 99 S.Ct. 421, 425, 58 L.Ed.2d 387, 394 (1978) (citation omitted)); State v. Wilson, 2004 SD 33, ¶ 24, 678 N.W.2d 176, 184 (passenger in a car lacks standing to challenge the legality of the driver’s consent).
[¶ 35.] We agree that Paul, as a passenger in a rental car, may challenge Akuba’s consent to search the vehicle only if she established “a legitimate expectation of privacy in the particular areas of the automobile searched.” Rakas, 439 U.S. at 148, 99 S.Ct. at 433, 58 L.Ed.2d at 404. In determining whether Paul had that legitimate expectation of privacy, we look for the following facts:
[A] legitimate presence in the area searched, possession or ownership of the area searched or the property seized, prior use of the area searched or the property seized, ability to control or exclude others’ use of the property, and a subjective expectation of privacy.
[421]*421Krebs, 504 N.W.2d at 587 (quoting United States v. Lochan, 674 F.2d 960, 965 (1st Cir.1982); United States v. Carter, 854 F.2d 1102, 1105 (8th Cir.1988)); Wilson, 2004 SD 33, ¶ 26, 678 N.W.2d at 184. We must also remember that Paul had the burden of proving her legitimate expectation of privacy in the area searched. Wilson, 2004 SD 33, ¶ 25, 678 N.W.2d at 184 (citing Rakas, 439 U.S. at 148, 99 S.Ct. at 433, 58 L.Ed.2d at 404); United States v. Salter, 358 F.3d 1080, 1084 n. 2 (8th Cir. 2004) (citing United States v. Gomez, 16 F.3d 254, 256 (8th Cir.1994)).
[¶ 36.] Here, however, Paul did not testify or present any evidence supporting any relationship with the rental vehicle, its trunk, or the duffel bags containing marijuana. That failure to present any evidence would normally be fatal to her motion because she carried the burden of proof. Wilson, 2004 SD 33, ¶25, 678 N.W.2d at 184. Moreover, Paul may have been unable to meet that burden because her brief maintains that she “never had access to the trunk; that she was never in possession of the keys to the vehicle; that she had no property in the trunk[,]” and that she “had no control over the trunk of the car, nor the ability to exclude others from entering it.”
[¶ 37.] Nonetheless, we address this issue because the trial court misapplied the applicable law and burden of proof. Although the State’s attorney argued that Paul “has not met her burden of showing a legitimate expectation of privacy,” the trial court disagreed, insisting that the detention of both Paul and Akuba was illegal, and further stating that the court’s “primary decision [was] based on [ ] the fruit of an illegal detention of this young lady rather than her expectation of privacy.” Additionally, when the State argued that Paul had the burden “to present some evidence to show that she has [an] expectation of privacy,” the trial court disagreed, and incorrectly placed that burden on the State:
COURT: Does not the State even — like When they are seeking to forfeit property — have to establish, first of all, that there is some evidence against her somehow tying the pot to her?
STATE: I don’t know anything about civil forfeiture.
COURT: It’s the same thing. You are saying, prove you’re innocent. Is there not a threshold burden for the State to come forward and show some eyidence of guilt before some connection — some connection to the contraband before the other party has to show some reason why it can’t be tied to them in one way or another?
STATE: In reading the Krebs decision,11 I don’t think there is, Your Hon- or. I mean, I can only rely on that ' decision and indicate to you that that court plainly said it was the passenger’s burden of proof to show expectation of privacy.
COURT: This is not stuff sitting .in the passenger seat. This is stuff that’s in a trunk in which the State is saying — and the critical arguments particularly on cars is she’s not an owner of this-vehicle, is not a renter of the motor vehicle and so she has — the State has to establish to me somewhere that that stuff hidden in the trunk of the car is her’s.
STATE: That’s the defendant’s burden of proof, Your Honor.
COURT: No. No. No. The people in this country don’t have to walk around prov[422]*422ing that they didn’t do something wrong.12 The first threshold is on the State to prove that they did do something wrong. The first interest here for the State is to establish that somehow or another she is connected to the pot in the trunk. It’s not sitting in the back seat. It’s not sitting in the glove compartment. She’s not smoking a joint. There is no connection between someone the State urges is simply riding in the car much like a hitchhiker.
[¶ 38.] After further discussion on the standing issue, the trial court continued to focus on the circumstances surrounding the stop and the request for consent to search without considering Paul’s standing. The court ultimately noted that its ruling was not based on any expectation of privacy (standing) by Paul. Rather, the trial court indicated that its decision was based on its ruling that the search was the fruit of an illegal detention. We have, however, determined that the trial court erred in that ruling. Therefore, Paul should have been given an opportunity to establish that she had a reasonable expectation of privacy in the trunk of the rental vehicle.13 However, we need not remand for a standing hearing because Akuba’s consent was valid. Because Akuba’s consent was valid, Paul could not prevail even if she had standing.
