Pursuаnt to C.A.R. 4.1, the prosecution brings this interlocutory appeal from a trial court order suppressing evidence found during a search of the defendant, Christopher Jo Reddersen, and his vehicle. The trial court based the order on its determination that Reddersen’s consent to search was involuntary. The trial court found Reddersen’s consеnt involuntary because the officer asked to search him without giving him a Miranda advisement while he was in custody. Challenging the order to suppress, the prosecution argues that the trial court’s ruling that Reddersen was in custody and that he involuntarily consented to the search was in error. We agree and hold that Reddersen was not in custody when the officer asked to search him because the officer was conducting a routine traffic stop. Routine traffic stops do not constitute custody for Miranda purposes as a matter of law. We further hold that the consent to search was voluntary. The trial court reasoned that the officer did not give Reddersen a Miranda advisement before obtaining his consent to search. The failure to give a Miranda advisement does not render a consent to search involuntary. Hence, we reverse.
I.
At around 4:00 a.m. on December 30,1998, Officer Deck Shaline of the Durango Police Department observed Reddersen driving his vehicle. Shaline had previous contact with Reddersen when Reddersen had been driving with expired license plates. Shaline suspected that the plates were still expired and *1179 began to follow Reddersen without turning on the overhead lights or sirens of his police unit. Another police officer also- followed Reddersen in a separate police unit.
Reddersen eventually parked his vehiсle in front of a friend’s house and got out of his vehicle. Shaline parked his police unit behind Reddersen’s vehicle and approached to ask about the license plates. At approximately the same time that Reddersen acknowledged that he was driving with expired plates, dispatch confirmed that, they were expired. Shaline then asked Reddersen for his driver’s license. Reddersen was cooperative and gave the officer his driver’s license.
Shaline radioed dispatch to check on the validity of the driver’s license and to make sure that Reddersen had no outstanding warrants. While waiting for dispatch to respond, the officer kept Reddersеn’s driver’s license. During that time, he asked Redder-sen if he had any illegal substances. Red-dersen responded, “I don’t think so.” Sha-line then asked Reddersen if he could search him. Reddersen agreed and began to empty his jean pockets, placing the items on the hood of his vehicle.
Shaline asked if he could search him further, and Reddersen аgain agreed. The officer found a cellophane package of white rocks mixed with a white powdery substance, which he suspected was methamphetamine, in the right-hand change pocket of Redder-sen’s jeans.
Shaline handcuffed, arrested and placed Reddersen in the patrol car. The officer conducted a search of Reddersen’s vehicle and found a glass pipe typically used to smoke methamphetamine. After taking Reddersen to the police station, Shaline advised him of his Miranda rights. The officer then proceeded to question Reddersen after he signed a waiver of rights form.
Based on the statements made at the police station and the items that the officer found during his search, Reddersen was charged with one count of unlawful possession of a schedule II controlled substance, 1 and one count of possession of drug paraphernalia. 2 Prior to trial, Reddersen moved to suppress the evidence seized during the search.
At the suppression hearing, the trial court found that Shaline subjected Reddersen tо a custodial interrogation without a Miranda advisement when he asked to search Redder-sen. Based on these findings, the trial court concluded that Reddersen’s consent to the search was involuntary and suppressed the evidence seized from the search.
The prosecution appeals the trial court’s suppression' ordеr arguing that Reddersen was not in custody when Shaline asked to search him and that Reddersen’s consent to the search was voluntary. We agree.
II.
In this case, we review two separate conclusions that the trial court made in its order to suppress the evidence seized from Redder-sen. 3 First, we find that the trial court erroneously concluded that Reddersen was in custody when Shaline asked for permission to search. The record shows that the questioning took place during a routine traffic stop. - Routine traffic stops do not constitute custody as a matter of law. Second, we find that' the trial court erroneously concluded that Reddersen’s consent to search was involuntary. In large part, the trial court found that Reddersen’s consent to search was involuntary because Shaline failed to advise Red-dersen of his Miranda rights. However, failure to advise a suspect of her Miranda rights alone does not render her consent involuntary, even when the suspect is in custody. After reviewing the evidence in the *1180 record and the trial court’s findings of fact, we concludе that Reddersen’s consent to search was voluntary.
III.
We begin by reviewing the trial court’s finding of custody. In reaching its conclusion that Reddersen’s consent was involuntary, the trial court made a finding that Reddersen gave his consent during a custodial interrogation. The prosecution contends that the trial court erred in finding that Reddersen was in custody рrior to his arrest. As a matter of law, we agree and hold that Reddersen was not in custody prior to his arrest because this encounter constituted a routine traffic stop,
Prior to any custodial interrogation, the interrogating officer must advise the suspect of her constitutional rights.
See Miranda v. Arizona,
As a general rule, routine traffic stops do not constitute custody for
Miranda
purposes.
See Berkemer v. McCarty,
When determining whether the police curtailed the defendant’s freedom to a degree associated with formal arrest during a stop, courts have looked to the force used by the police. In
Breidenbach,
we found that the suspect was in custody for
Miranda
purposes when the police drew their weapons during
an
investigatory stop.
See Breidenbach,
In this case, the trial court found that Reddersen was in custody “[o]nce Officer Shaline confirmed his suspicion by observing the license plate, contacted the [defendant, obtained his driver’s license, and radioed in for a confirmation of status of the license.” Under those circumstances, the trial court concluded that “any reasonable person in the [dеfendant’s position would have considered himself deprived of his freedom of action, and would not feel that he was free to leave.” We disagree and find that the encounter between Shaline and Reddersen amounted to a routine traffic stop.
In contrast to the trial court’s conclusion, routine traffic stops do not сonstitute custody for
Miranda
purposes, even though “a traffic stop significantly curtails the ‘freedom of action’ of the driver and the passengers.”
Berkemer,
Here the record indicates that the traffic stop lasted a short period of time. According to Shaline’s uncontroverted testimony, less than five minutes passed from the time he approached Reddersen to the timé he asked to search him. The officer testified that his demeanor was relaxed and non-confrontational since he had previous contact with Reddersen. The trial court found that “the officer did nothing threatening [or] coercive” during the stop. Consistent with this testimony, Reddersen testified that Shaline never drew his gun. The officer’s questioning and subsequent search took place in a public street. The officer did not instruct Reddersen to get into the patrol car or confine him in any оther way. The Stop occurred only because Reddersen’s license plates were still not current.
Unlike the facts of this case, courts have held that a suspect was in custody during an investigatory stop as a result of the force used by the police. In such encounters, the police either drew their weapons or handсuffed the suspect at some point during the stop.
See Perdue,
In conclusion, we disagree with the ruling of the trial court that Reddersen was in custody prior to his arrest. We hold that the record supports the opposite conclusion that this encounter was simply a routine traffic stop. Consistent with United States Supreme Court рrecedent, we have recognized that a routine traffic stop does not constitute custody for
Miranda
purposes.
See Wallace,
IV.
We now address the ruling of the trial court that Reddersen’s consent to search was involuntary. The trial court relied largely on the fact that Shalinе did not give Reddersen a Miranda advisement. However, Shaline’s failure to give Reddersen a Miranda advisement does not render his consent involuntary. After reviewing the evidence in the record and the trial court’s findings of fact, we conclude that Reddersen’s consent was voluntary.
A.
We begin our discussion with an overview of the applicable constitutional principles. The Fourth Amendment to the United States Constitutiоn and Article II, Section 7, of the Colorado Constitution prohibit war-rantless searches of one’s person or property.
See People v. Licea,
A consensual search is involuntary when “it is the result of duress or coercion, express or implied, or any other form of undue influence exercised against the defendant.”
People v. Magallanes-Aragon,
B.
Finding Reddersen’s consent involuntary, the trial court relied on the fact that Shaline did nоt give Reddersen a Miranda advisement before asking to search him. The trial court found that “[ajlthough aside from failing to advise the [defendant of his rights, the officer did nothing threatening, coercive, or which otherwise might have rendered his consent involuntary, the fact that he was in custody, in the presence of two armed, uniformed police offiсers, late at night, persuades this [cjourt to conclude that the consent given by the [defendant to search his person was involuntary.”
The voluntariness of a consent to search is a question of fact to be determined by the trial court.
See People v. Drake,
After reviewing the record, we conclude that it contains no evidence to support the trial court’s determination that Reddersen’s consent was involuntary. Rather, the trial court’s findings, which are supported by the record, require the conclusion that Redder-sen’s consent was voluntary.
Initially, the trial court found that Redder-sen agreed to the search. The court also found that Reddersen had extensive experience with traffic, stops and knew that hе could refuse the officer’s request to search him. According to Shaline’s uncontested testimony, the encounter was non-confrontational and lasted a short period of time. After considering Reddersen’s experience and the circumstances of the search, the trial court concluded that “the officer did nothing threаtening, coercive, or which otherwise might have rendered the consent involuntary.” The court found that the consent was involuntary because Shaline did not advise Reddersen of his Miranda rights before asking to search him.
However, failure to give a
Miranda
advisement does not render the consent to search involuntary.
See Licea,
Based on the record and the trial court’s finding that Shaline’s conduct was non-coercive, we conclude that Reddersen’s consent to search was voluntary. We accept the trial *1183 court’s finding that Shaline “did nothing threatening, coercive, or which otherwise might have rendered his consent involuntary,” because it is supported by the record. However, we find error in the conclusion of the trial court that Shaline’s failure to give Reddersen Miranda warnings rendered the search involuntary.
V.
We reverse the trial court оrder suppressing the evidence found on Reddersen’s person, and in his vehicle, and return this case for further proceedings consistent with this opinion.

. See § 18-18-428, 6 C.R.S. (1999).
. The prosecution presented the following two issues for our review:
A. Did the Trial Court err in finding that police conducted an illegal search of the defendant by finding that failure to give a Miranda warning rendered a consent to search involuntary?
B. Did the Cоurt err in finding that the defendant was in custody merely because the officer had the defendant’s driver’s license and was awaiting confirmation on license status when the defendant was asked for consent to search his person?
. Police-citizen encounters fall into three categories: arrests, investigatory stops and consensuаl interviews.
