OPINION
DAVIS, Judge:
{1 Defendant Shayne Michael Hansen (Hansen) appeals his conviction for illegal possession of a controlled substance, a third degree felony, in violation of Utah Code Ann. § 58-87-8(2)(a)(i) (1998).
BACKGROUND
12 On December 11, 1998, Officer Bruce Huntington of the Midvale City Police Department was driving behind Hansen. Officer Huntington initiated a computer check of Hansen's vehicle with the Utah Division of Motor Vehicles. While Officer Huntington waited for the results of the computer check, he observed Hansen make an improper left turn.1 After Officer Huntington observed the turn, the computer check revealed that Hansen's car was uninsured. Due to these violations, Officer Huntington decided to stop the vehicle, and he activated his overhead emergency lights Hansen pulled off the road and stopped in the parking lot of a convenience store. Officer Huntington parked directly behind Hansen.2
13 Officer Huntington, dressed in uniform and carrying a sidearm, exited his patrol car and confronted Hansen. Officer Huntington told Hansen that he stopped him because of the improper lane change and lack of insurance. Hansen admitted that the did not have any insurance and stated that he could not afford insurance. Officer Huntington requested Hansen's driver's license and registration, and returned to his patrol ear to run a computer check on Hansen. After approximately five minutes, the computer check revealed that Hansen's ligense was valid, and Hansen did not have any outstanding warrants. Officer Huntington then exited his patrol car and returned to Hansen. While Officer Huntington was walking back to Hansen's vehicle, another officer pulled into the parking lot. This second officer parked next to Officer Huntington's car, got out of his patrol car, and remained by the patrol cars. The emergency lights on both patrol cars were flashing, and they remained flashing throughout the encounter.
T4 Upon returning to Hansen's vehicle, Officer Huntington told Hansen that state law required him to have automobile insurance, and Hansen needed to have an insurance agent mail proof of insurance to the Division of Motor Vehicles. Officer Huntington did not say anything to Hansen regarding the improper lane change. Officer Huntington then returned Hansen's driver's license and registration; however, Officer Huntington did not tell Hansen that he was free to leave. Instead, Officer Huntington asked Hansen if he had any alcohol, weapons, or drugs in his vehicle. Hansen replied that he did not have any such items. Officer Huntington then asked Hansen, "Do you mind if I check?"3 Officer Huntington testi[1138]*1138fied that Hansen responded, "Yes." 4
T5 Officer Huntington then told Hansen and his passenger to step out of the car, and Officer Huntington directed them to stand next to the other officer. Officer Huntington conducted a search of the car where he found a homemade billy club and a marijuana pipe on the floor of the driver's area of the car. Officer Huntington arrested Hansen and searched him incident to the arrest. During the search of Hansen, Officer Huntington found a substance he suspected to be methamphetamine. Hansen was later charged with possession of a controlled substance in violation of Utah Code Ann. § 58-8%¢-8(2)(a)(i) (1998), and unlawful possession of drug paraphernalia in violation of Utah Code Ann. § 58-87a-5 (1998).
T6 Prior to trial, Hansen moved to suppress evidence obtained in the searches, claiming that Officer Huntington illegally detained him and that he did not voluntarily consent to the search of his car. The trial court denied Hansen's motion to suppress, concluding that the evidence was. lawfully seized because "[alt the time consent was obtained, there was no seizure for Fourth Amendment purposes because defendant was free to leave," and "[dlefendant's consent to search was freely and voluntarily given." Hansen later entered a conditional guilty plea to unlawful possession of a controlled substance. Hansen now appeals the trial court's denial of his motion to suppress.
ISSUES AND STANDARDS OF REVIEW
Y7 Hansen alleges that the trial court erred in denying his motion to suppress because Officer Huntington's search violated his Fourth Amendment right against unreasonable searches and seizures. Specifically, Hansen argues that his consent to search was not valid because it was obtained through Officer Huntington's exploitation of an illegal seizure, and his consent was not voluntarily given.5
[Bljecause the determination of whether an encounter with law enforcement officers constitutes a seizure under the Fourth Amendment "' "calls for consistent application from one police encounter to the next, regardless of the particular individual's response to the actions of the police," '" such determination is a legal conclusion that we review for correctness.
Salt Lake City v. Ray, 2000 UT App 55, ¶ 8, 998 P.2d 274 (citations omitted). Similarly, the trial court's ultimate conclusion that consent was voluntary or involuntary is reviewed for correctness. See State v. Thurman, 846 P.2d 1256, 1271 (Utah 1993). However, "[The trial court's underlying factual findings will not be set aside unless they are found to be clearly erroneous." Id.
ANALYSIS
I. Nature of the police encounter
18 Hansen argues that the trial court erred in its conclusion that, at the time the consent was obtained, there was no seizure for Fourth Amendment purposes because Hansen was free to leave.
The Fourth Amendment of the United States Constitution guarantees the "right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures." U.S. Const. amend. IV. The United States Su[1139]*1139preme Court has held that "stopping an automobile and detaining its occupants constitute[s] a seizure" within the meaning of the Fourth Amendment, "even though the purpose of the stop is limited and the resulting detention quite brief." Delaware v. Prouse, 440 U.S. 648, 653, 99 S.Ct. 1391, 59 L.Ed.2d 660 (1979). Thus, "(allthough a person has a lesser expectation of priva-ey in a car than in his or her home, one does not lose the protection of the Fourth Amendment while in an automobile." State v. Schlosser, P.2d 1132, 1135 (Utah 1989) (citation omitted).
State v. Lopez, 873 P.2d 1127, 1131 (Utah 1994) (alteration in original).
19 "In reviewing the legality of a traffic stop, we consider two questions: [Whether the officer's action was justified at its inception, and whether it was reasonably related in seope to the circumstances which justified the interference in the first place."" State v. Patefield, 927 P.2d 655, 657 (Utah Ct.App.1996) (alteration in original) (quoting Terry v. Ohio, 392 U.S. 1, 20, 88 S.Ct. 1868, 1879, 20 L.Ed.2d 889 (1968)); accord Lopez, 873 P.2d at 1131-32. With respect to the first question, a police officer is constitutionally justified in stopping a vehicle if the stop is "incident to a traffic violation committed in the officers' presence." State v. Talbot, 792 P.2d 489, 491 (Utah Ct.App.1990); see also State v. Marshall, 791 P.2d 880, 881-83 (Utah Ct.App.1990); State v. Sierra, 754 P.2d 972, 975 (Utah Ct.App.1988).
110 Here, Hansen was seized by Officer Huntington when he was stopped for the improper lane change and lack of insurance. It is clear that Officer Huntington was justified in seizing Hansen because Hansen committed two traffic violations in the officer's presence. Consequently, Hansen does not dispute the legality of the initial stop and the first part of the Terry inquiry is not at issue.
111 The second question in reviewing the legality of a traffic stop is whether the stop was reasonably related in scope to the traffic violation which justified it in the first place. See Patefield, 927 P.2d at 657. "Once a traffic stop is made, the detention 'must be temporary and last no longer than is necessary to effectuate the purpose of the stop.'" Lopez, 873 P.2d at 1132 (quoting Florida v. Royer, 460 U.S. 491, 103 S.Ct. 1319, 75 L.Ed.2d 229 (1983)). Both "[the length and scope of the detention must be 'strictly tied to and justified by' the cireum-stances which rendered its initiation permissible." State v. Johnson, 805 P.2d 761, 763 (Utah 1991) (quoting Terry, 392 U.S. at 19-20, 88 S.Ct. 1868). Therefore,
[aln officer conducting a routine traffic stop may request a driver's lHceense and vehicle registration, conduct a computer check, and issue a citation. United States v. Guzman, 864 F.2d 1512, 1519 (10th Cir.1988). However, onee the driver has produced a valid license and evidence of entitlement to use the vehicle, "he must be allowed to proceed on his way, without being subject to further delay by police for additional questioning." Id.
State v. Robinson, 797 P.2d 431, 435 (Utah Ct.App.1990). "Investigative questioning that further detains the driver must be supported by reasonable suspicion of more serious criminal activity. Reasonable suspicion means suspicion based on specific, articulable facts drawn from the totality of the circumstances facing the officer at the time of the stop." Lopez, 873 P.2d at 1132.
{12 Here, Hansen claims that he was illegally seized at the time the alleged consent was obtained because Officer Huntington engaged in investigative questioning without reasonable suspicion of more serious criminal activity. The State counters that when Officer Huntington gave Hansen a warning and returned his license and registration, the encounter between Officer Huntington and Hansen ceased to be a seizure under the Fourth Amendment.
Under Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968), and its progeny, there are three levels of police-citizen encounters, each requiring a different degree of justification under the Fourth Amendment. State v. Munsen, 821 P.2d 13, 15 n. 1 (Utah App.1991), cert. denied, 843 P.2d 516 (Utah 1992). The first level occurs when an officer approaches and questions a suspect. An officer may stop and question a person at any time so long [1140]*1140as that person "is not detained against his [or her] will" Id. The next level is reached when an officer temporarily seizes a person. In order to legally effect a temporary seizure, the officer must have "articulable suspicion" that the suspect has or is about to commit a crime, and the detention must be limited in scope. Id. The third level is arrest, which requires probable cause for the officer to believe that a crime has been or is about to be committed. Id.
Salt Lake City v. Smoot, 921 P.2d 1003, 1006 (Utah Ct.App.1996) (alteration in original). The Supreme Court of Utah has declared:
Not every encounter between a police officer and a citizen is a seizure. A person is seized under the Fourth Amendment when, considering the totality of the circumstances, the police conduct would have communicated to a reasonable person that the person was not free to decline the officer's requests or otherwise terminate the encounter and go about his or her business.
State v. Higgins, 884 P.2d 1242, 1244 (Utah 1994) (internal citations omitted).
Illustrating this standard, the United States Supreme Court noted: "Examples of cireumstances that might indicate a seizure, even where the person did not attempt to leave, would be the threatening presence of several officers, the display of a weapon by an officer, some physical touching of the person of the citizen, or the use of language or tone of voice indicating that compliance with the officer's request might be compelled."
State v. Patefield, 927 P.2d 655, 659 (Utah Ct.App.1996) (quoting United States v. Mendenhall, 446 U.S. 544, 554, 100 S.Ct. 1870, 1877, 64 L.Ed.2d 497 (1980)). Furthermore,
[oInee a person is seized for Fourth Amendment purposes, the seizure does not cease simply because the police formulate an uncommunicated intention that the seized person may go on his or her way. For the seizure to end, it must be clear to the seized person, either from the words of an officer or from the clear import of the circumstances, that the person is at Wherty to go about his or her business.
Higgins, 884 P.2d at 1244 (emphasis added).
{13 In the present case, the trial court concluded that the detention did not exceed the scope of the traffic stop and that at the time Hansen consented to the search, there was no seizure for Fourth Amendment purposes. We disagree. The record clearly indicates that neither the words of Officer Huntington nor the clear import of the circumstances would have communicated to a reasonable person that the person was free to decline the officer's requests, terminate the encounter, and go about his or her business. Although Officer Huntington returned Hansen's driver's license and registration, given the surrounding cireumstances, this act alone would not have communicated to a reasonable person that he or she was free to leave. See United States v. Sandoval, 29 F.3d 537, 540 (10th Cir.1994) ("In the context of traffic stops this Cireuit has adopted as an indicium of a seizure the officer's taking of necessary documentation (driver's license and vehicle registration) from a driver, and we have also considered as a necessary (but not always sufficient) condition of the termination of that seizure the officer's return of such documentation. ..."). For example, after Officer Huntington returned Hansen's license and registration, Officer Huntington did not say anything to Hansen that would have indicated that Hansen was free to go. We recognize that an officer is not required to inform a detainee that they are free to go, see Ohio v. Robinette, 519 U.S. 33, 38, 117 S.Ct. 417, 421, 136 L.Ed.2d 347 (1996); however, such a statement would have supported the trial court's conclusion that Hansen was not seized at the time he gave consent. See United States v. Torres-Guevara, 147 F.3d 1261, 1265 (10th Cir.1998) (stating defendant was not seized for Fourth Amendment purposes, in part, because officers told defendant she was free to leave); United States v. Gregory, 79 F.3d 973, 979 (10th Cir.1996) ("Although not prerequisites, in determining whether consent is voluntary when given following the return of defendant's documents, we look at such factors as whether the officer informed. the defendant that he was free to leave the scene or that he could refuse to [1141]*1141give consent."); United States v. McSwain, 29 F.3d 558, 563 (10th Cir.1994) (same).
14 Not only did Officer Huntington fail to communicate to Hansen that he was free to leave, the question that Officer Huntington asked Hansen-"Do you have any drugs, al-cobol or weapons in the car?"-communicated the message that Hansen was not free to leave. This question, although not directly accusatory, was clearly investigatory, indicating that Officer Huntington suspected that Hansen was engaged in some sort of illegal activity. Therefore, investigatory questions such as the one asked here actually cut against the proposition that a reasonable person would feel that the initial seizure has ended and that he or she is now free to terminate the encounter. Cf. Sandoval, 29 F.3d at 542 (stating that the crucial predicate to a voluntary police citizen encounter was missing because "[alt no point did the nature of those inquiries [about defendant's drug involvement] change the climate so that the reasonable listener would view participation in the exchange as freely terminable"); Washington v. Soto-Garcia, 68 Wash.App. 20, 841 P.2d 1271, 1273-74 (1992) (holding that progressive intrusion into defendant's privacy was of such a nature that a reasonable person would not believe that he or she was free to end the encounter).
115 In addition to Officer Huntington's words, the clear import of the cireumstances in the present case would not have indicated to a reasonable person that he or she was free to leave. Officer Huntington remained at Hansen's vehicle and continued to ask Hansen questions, both Officer Huntington and a second armed officer's vehicles remained parked behind Hansen with their emergency lights flashing, and the second officer remained outside his vehicle throughout the encounter. Finally, Officer Hunting, ton did not make any indication to Hansen as to how he intended to handle the improper lane change before he asked Hansen if he had any alcohol, weapons, or drugs in the vehicle. Officer Huntington merely told Hansen to have his insurance agent call the Division of Motor Vehicles, and he returned Hansen's license and registration. Because of the clear import of the cireumstances, especially the fact that Officer Huntington had not addressed one of the reasons for the initial stop, a reasonable person would not have felt free to terminate the encounter and proceed on his or her way.
T16 Due to the factors discussed above, we find that Hansen remained seized for Fourth Amendment purposes when, and because, Officer Huntington asked him whether there was alcohol, drugs, or weapons in the vehicle. Likewise Hansen was seized for Fourth Amendment purposes when Officer Huntington requested consent to search the car. The State concedes that Officer Huntington did not have a reasonable articulable suspicion of more serious eriminal activity to justify the investigative questions. Therefore, Hansen was illegally detained when Officer Huntington asked him questions that were not reasonably related in scope to the traffic violation which justified the initial sei-zare. See United States v. Walker, 933 F.2d 812, 816 (10th Cir.1991) (holding that defendant was unreasonably seized under Fourth Amendment when officer detained him to ask questions unrelated in scope to the reasons that justified the initial traffic stop).
II. Voluntariness of Consent
{17 We now turn to the issue of whether Hansen's consent to search was valid despite the illegality of Officer Huntington's seizure.
A warrantless search is a per se Fourth Amendment violation unless the State can establish one of the " 'few specifically established and well-delineated exceptions. " State v. Arroyo, 796 P.2d 684, 687 (Utah 1990) (quoting Kaitz v. United States, 389 U.S. 347, 357, 88 S.Ct. 507, 514, 19 LEd.2d 576 (1967) (citations omitted)); accord State v. Sepulveda, 842 P.2d 913, 918 (Utah App.1992). One of the clearly established exeeptions is a consent. Arroyo, 796 P.2d at 687; Sepulveda, 842 P.2d at 918.
State v. Ham, 910 P.2d 433, 438 (Utah Ct.App.1996).
118 "[A] defendant's consent to a search following illegal police activity is valid under the Fourth Amendment only if both of the following tests are met: (i) The consent was given voluntarily, and (i) the consent was not obtained by police exploita[1142]*1142tion of the prior illegality." State v. Thurman, 846 P.2d 1256, 1262 (Utah 1993); see also State v. Arroyo, 796 P.2d 684, 688 (Utah 1990). "It is the State's burden to prove that a consent was voluntarily given...: If the State fails to meet this burden, the evidence is deemed inadmissible against the defendant." Ham, 910 P.2d at 439; accord Thurman, 846 P.2d at 1263; State v. Robinson, 797 P.2d 431, 437 (Utah Ct.App.1990). This court has adopted the following analytical framework to determine whether the State has met its burden of proving that consent was voluntarily given:
'(1) There must be clear and positive testimony that the consent was "unequivocal and specific" and "freely and intelligently given"; (2) the government must prove consent was given without duress or coercion, express or implied; and (3) [when evaluating these first two standards, wel indulge every reasonable presumption against the waiver of fundamental constitutional rights and there must be convincing evidence that such rights were waived.!
Ham, 910 P.2d at 439 (citations omitted) (alterations in original). In determining whether consent was voluntarily given we will look to the "totality of all the cireum-stances." Schneckloth v. Bustamonte, 412 U.S. 218, 227, 98 S.Ct. 2041, 2048, 36 L.Ed.2d 854 (1973); accord Ham, 910 P.2d at 439.
119 As stated above, Hansen was illegally seized at the time Officer Huntington requested consent to search Hansen's vehicle. Therefore, for the evidence discovered in the search to be admissible, Hansen's consent, if given, must have been voluntary, and the consent must not have been obtained by police exploitation of the prior illegality. The trial court concluded that Hansen's "consent to search was freely and voluntarily given." 6 We disagree for the following reasons.
120 First, Officer Huntington's testimony was neither clear nor positive regarding Hansen's response to his second question. See Ham, 910 P.2d at 439 (requiring testimony that consent was unequivocal and specific and freely and intelligently given). Specifically, the following colloquies took place:
Q. [Prosecutor] And then you asked, "Do you mind if I check?"
A. [Officer Huntington] Uh-huh.
Q. And what was his response to that question?
A. He said yes.
Q. [Court] Yes, he minded?
A. Yes, I could have consent to search.
[[Image here]]
Q. [Defense Counsel] Do you recall specifically what you said to him?
A. -Not specifically.
Q. Do you have any idea?
A. I would imagine that I stated: "Do you have any alcohol, drugs or weapons in the vehicle?"
He said no? ©
He said no. Do you mind if I check? yr
Okay. o
And then he said yes. >
{Court] He said? [Defense Counsell He says yes? eo
[Officer Huntington] Yes. >
. [Court] Do you mind if I check-and he says yes? o
A. Well, do you mind if I check and then yes, he gave me consent. Sorry.
[[Image here]]
[Defense Counsel] What did he say? 0
What did he say? p
Yeah. o
. I don't recall exactly other than it was consent. >
Q. So you don't recall his exact words?
A. Not exactly.
121 Officer Huntington testified twice that he asked Hansen, "Do you mind if I check?" and Hansen responded, "Yes." The court clearly realized the import of officer Huntington's testimony and interrupted the attorneys in an effort to clarify Officer Hunt[1143]*1143ington's testimony. However, Officer Huntington's responses to the court's questions were conclusory rather than "clear and positive testimony" that Hansen's reply was " 'unequivocal and specific.'" Ham, 910 P.2d at 439 (citations omitted). Moreover, Officer Huntington admitted that he did not recall Hansen's exact words. Therefore, we hold that the trial court's determination that the testimony was clear and positive that Hansen's response was unequivocal and specific was incorrect. To the extent its determination amounted to a finding of fact, it was clearly erroneous.
122 The Ham analytical framework requires us to next address whether Hansen's response was freely and intelligently given and obtained without duress or coercion, express or implied.7 See Ham, 910 P.2d at 439.
[The Fourth and Fourteenth Amendments require that a consent not be coerced, by explicit or implicit means, by implied threat or covert force. For, no matter how subtly the coercion was applied, the resulting "consent" would be no more than a pretext for the unjustified police intrusion against which the Fourth Amendment is directed.
Schneckloth, 412 U.S. at 228, 93 S.Ct. 2041.
In examining all the surrounding cireum-stances to determine if in fact the consent to search was coerced, a court must take into account both the details of police conduct and the characteristics of the accused, Arroyo, 796 P.2d at 684[,] which include "subtly coercive police questions, as well as the possibly vulnerable subjective state of the person who consents." Schneckloth, 412 U.S. at 229, 93 S.Ct. at 2049.
State v. Robinson, 797 P.2d 431, 437 (Utah Ct.App.1990) (emphasis added).
T23 The present case is quite similar to Ohio v. Robinette, 80 Ohio St.3d 234, 685 N.E.2d 762 (1997). In Robinette, an officer stopped the defendant for a speeding violation. See id. at 764. The officer issued the defendant a verbal warning for the speeding violation, and returned the defendant's driver's license. See id. The officer then said to the defendant, "One question before you get gone [sic]: are you carrying any illegal contraband in your car? Any weapons of any kind, drugs, anything like that?" Id. When defendant responded that he did not have any contraband in the car, the officer asked if he could search the vehicle See id. The defendant answered "yes" to the officer's request. See id. On remand from the Supreme Court of the United States, see Ohio v. Robinette, 519 U.S. 33, 117 S.Ct. 417, 136 L.Ed.2d 347 (1996), the Supreme Court of Ohio looked at the totality of the cireum-stances to determine whether a reasonable [1144]*1144person would have believed that they could refuse to answer further questions and leave. See Robinette, 685 N.E.2d at 769. The court then ruled that
[the officer's] words did not give Robinette any indication that he was free to go, but rather implied just the opposite-that Ro-binette was mot free to go until he answered [the officer's] additional questions. The timing of [the officer's] immediate transition from giving Robinette the warning for speeding into questioning regarding contraband and the request to search is troubling.... "The transition between detention and a consentual [sic] exchange can be so seamless that the untrained eye may not notice that it has occurred. The undetectability of that transition may be used by police officers to coerce citizens into answering questions that they need not answer, or to allow a search of a vehicle that they are not legally obligated to allow." . When these factors are combined with a police officer's superior position of authority, any reasonable person would have felt compelled to submit to the officers questioning.
Id. at T7iO-71 (citation omitted) (emphasis in original).
€24 Here, as in Robinette, the intrusive and suspicious questions asked by the officer, combined with the fact that the questions were asked immediately after the defendant was detained, indicate that a reasonable person would not have felt free go until they answered the additional questions. Furthermore, although the questions were not expressly coercive, the circumstances surrounding the request to search made the request subtly coercive. Specifically, Officer Huntington had only issued a warning regarding the lack of insurance and he had not taken any action regarding the improper left turn. Therefore, a reasonable person would not have felt that their consent, if given, was a voluntary act of free will because Officer Huntington could have cited Hansen for the improper lane change if Hansen was uncooperative regarding the search.8 See Florida v. Royer, 460 U.S. 491, 497, 103 S.Ct. 1319, 1324, 75 L.Ed.2d 229 (1983) ("[Wlhere the validity of a search rests on consent, the State has the burden of proving that the necessary consent was obtained and that it was freely and voluntarily given. ...") (emphasis added).
125 Officer Huntington did not provide clear and positive testimony that Hansen's alleged consent was unequivocal and specific. Furthermore, in looking at the totality of the cireumstances, it is clear that officer Huntington's request was coercive, and a reasonable person would not have felt free to ignore Officer Huntington's request. Therefore, because we indulge every reasonable presumption against the waiver of fundamental constitutional rights, see Ham, 910 P.2d at 439, we hold that the trial court erred in concluding that Hansen's consent was freely and voluntarily given.9
CONCLUSION
126 We conclude that the trial court erred in denying Hansen's motion to suppress the evidence obtained in the search of Hansen's car. Hansen was illegally detained when Officer Huntington asked for consent to search Hansen's vehicle. Officer Huntington did not provide clear and positive testimony that Hansen's alleged consent was unequivocal and specific and freely and intelligently given. In addition, the State did not prove that Hansen's alleged consent was giv[1145]*1145en without duress or coercion. Consequently, Officer Huntington's search of Hansen's vehicle violated Hansen's rights under the Fourth Amendment and the trial court erred in denying his motion to suppress the evidence discovered in the search.
127 Reversed and remanded for further proceedings consistent with this opinion.
