¶ 1 The Commonwealth appeals from the suppression court’s order entered October 6, 1997,1 granting Winifred Mann-*198ion’s motion to suppress oral and written statements made by her to Pennsylvania State Troopers. We reverse and remand for a trial.2
¶ 2 When reviewing an appeal from a suppression court’s decision, we must first determine whether the record supports the court’s factual findings. Commonwealth v. Williams, 539 Pa. 61, 71, 650 A.2d 420, 425 (1994). When the Commonwealth appeals from a suppression court’s decision, we consider only the evidence of the defendant’s witnesses and so much of the prosecution’s evidence that remains uncontradicted when fairly read in the context of the record as a whole. Commonwealth v. Prosek, 700 A.2d 1305, 1307 (Pa.Super.1997). We are bound by the suppression court’s factual findings when the evidence supports those findings; however, we may reverse the suppression court when it draws erroneous legal conclusions from those factual findings. Williams, 539 Pa. at 71-72, 650 A.2d at 426.
¶ 3 The record reflects the following facts. On June 24, 1996, Pennsylvania State Trooper John David Milligan traveled to the French Creek Sheep and Wool Company (“French Creek”) to investigate an alleged theft of approximately $200,000 taken from French Creek. Eric and Jean Flaxenburg, the owners of French Creek, alleged that Mannion, French Creek’s former bookkeeper, perpetrated the theft. During this investigation, Trooper Milligan obtained from the Flaxenburgs tally sheets prepared by French Creek’s current bookkeeper. These tally sheets purported to demonstrate a theft.
¶ 4 On June 26, 1996, Trooper Milligan and Pennsylvania State Trooper John V. Sauers, both dressed in street clothes, traveled to Mannion’s Chester County residence. Trooper Milligan had a weapon concealed under his suit coat. The troopers knocked on Mannioris door, identified themselves as state police troopers, and stated that they were investigating an alleged theft of approximately $200,000 taken from French Creek. Mannion expressed her familiarity with the allegations, and stated that she had received a notice of intent to sue civilly filed against her by the Flaxenburgs. She also stated that because she viewed the troopers as neutral, she believed they could help her explain the situation to the Flaxenburgs. Mannion expressed her willingness to discuss the matter with the troopers, and invited them into her home. At that time, Trooper Sauers told Mannion that she: was not under arrest; was not required to speak with the troopers; could ask the troopers to leave at anytime; and could have an attorney present.
¶ 5 The troopers interviewed Mannion in her living room for approximately Vh hours. During this time, Trooper Milligan reviewed the tally sheets with Mannion. Mannion denied any involvement in the theft. She stated that any error resulted from sloppy bookkeeping and the use of cash versus checks to pay certain suppliers that refused to take French Creek’s checks. During and after this interview, neither trooper was convinced that a theft, as opposed to an accounting error, had occurred; or, if one had occurred, that Mannion was the perpetrator.
¶ 6 At the conclusion of the interview, Troopers Milligan and Sauers informed Mannion of their intention to return to French Creek to obtain further explanation and documentation from the Flaxenburgs. The troopers stated that they would telephone Mannion after they spoke with the Flaxenburgs to arrange for another meeting. The troopers informed Mannion that if she agreed to another meeting, it could take place at her home, her attorney’s office, or the police barracks. Mannion expressed her agreement with this arrangement.
¶ 7 On June 27, 1996, Trooper Sauers obtained additional documentation from the Flaxenburgs, which he gave Trooper Milli-gan. Trooper Milligan then telephoned Mannion and arranged a second meeting at her home on June 28, 1996 at 10:00 a.m.
¶ 8 Troopers Milligan and Sauers, both dressed in street clothes, arrived at Mann-*199ion’s home at approximately 10:30 a.m. on June 28,1996. Trooper Milligan had a weapon concealed under his suit jacket. When the troopers arrived, neither was convinced that a theft had occurred; or, if one had taken place, that Mannion was the perpetrator. The troopers knocked on Mannion’s door, and she invited them in. Trooper Sauers then told Mannion that she: was not required to speak with them; was free to stop speaking with them at any time; and could ask them to leave at any time.
¶ 9 The troopers and Mannion commenced their conversation in the living room, but later moved to Mannion’s dining room table to better examine the additional documentation furnished by the Flaxenburgs. During this meeting, Mannion offered the troopers tea or coffee and moved about freely as she smoked cigarettes. When her telephone rang, she asked permission to answer. In response, Trooper Sauers told Mannion that she was free to do as she wished. Mannion then answered the telephone and engaged in a conversation for roughly five minutes.
¶ 10 Approximately two hours into the interview, Mannion stated that she paid French Creek’s electric and postage bills in cash. This statement caused both troopers to doubt Mannion’s credibility. Trooper Sauers told Mannion that he did not believe a company the size of French Creek would pay utility and postage bills in cash because receipts were necessary for tax purposes. Trooper Sauers stated that he believed Mannion was lying, that things were not looking good for her, and that she was going to be arrested at some point in time. Trooper Sauers then stood up and walked beside Mannion. As Trooper Sauers stood alongside Mannion, he said in a low voice that he did not believe French Creek would pay its electric bills in cash. He also said that he believed Mannion was lying and thought that she took the money to help her children.
¶ 11 At this point, Mannion began to cry and stated that: the Flaxenburg children had so much and were spoiled brats; she took the money to help her children because they deserved a better life; and Trooper Sauers was right. When Mannion stopped crying, she agreed to give a written statement, which she wrote on blank pages taken from Trooper Milligan’s notebook. Mannion then asked whether the troopers were going to “drag her out of the house in cuffs.” Trooper Sauers responded that Mannion would not be arrested that day. He explained that a complaint would be filed with the district justice’s office and that Mannion would be notified and given an opportunity to turn herself in. Trooper Sauers further explained that Mann-ion would only be physically removed from her home if she failed to respond to the criminal complaint. Approximately one month later, on July 22, 1996, Mannion was formally charged with theft by unlawful taking or disposition and receiving stolen property.
¶ 12 Prior to trial, Mannion moved to suppress her statements to the troopers, alleging that she was not given Miranda3 warnings and the statements were the product of a custodial interrogation. After a hearing, the suppression court granted Mannion’s motion.
¶ 13 The Commonwealth filed a motion to reconsider. In response, the suppression court vacated its original order, accepted written submissions from counsel, heard reargument, and issued a second order that essentially reinstated its original order.4 The Commonwealth appealed, and a panel of this Court affirmed the suppression court’s order. We thereafter granted the Common*200wealth’s petition for reargument era bane and withdrew our previous decision. This appeal followed.
¶ 14 The Commonwealth frames its issue on appeal as follows:
Did the lower court commit an error of law by suppressing defendant’s statements while utilizing a legally incorrect definition of custody, and erroneously concluding that a reasonable person, under the circumstances confronting this defendant, could have perceived herself to be in custody?
Appellant’s Brief at 4.
¶ 15 We first address the Commonwealth’s claim that the suppression court used a legally incorrect definition of “custody” when determining whether Mann-ion’s statements were the product of custodial interrogation so as to require Miranda warnings. A law enforcement officer must administer Miranda warnings prior to custodial interrogation. Commonwealth v. Johnson, 373 Pa.Super. 312, 541 A.2d 332, 336 (1988). The standard for determining whether an encounter with the police is deemed “custodial” or police have initiated a custodial interrogation is an objective one based on a totality of the circumstances, with due consideration given to the reasonable impression conveyed to the person interrogated. Commonwealth v. Gwynn, — Pa. -, -, 723 A.2d 143, 148 (1998). Custodial interrogation has been defined as “questioning initiated by law enforcement officers after a person has been taken into custody or otherwise deprived of his [or her] freedom of action in any significant way.” Johnson, 541 A.2d at 336 quoting Miranda v. Arizona, 384 U.S. 436, 444, 86 S.Ct. 1602, 1612, 16 L.Ed.2d 694, 706 (1966). “Interrogation” is police conduct “calculated to, expected to, or likely to evoke admission.” Id. quoting Commonwealth v. Simala, 434 Pa. 219, 226, 252 A.2d 575, 578 (1969). When a person’s inculpatory statement is not made in response to custodial interrogation, the statement is classified as gratuitous, and is not subject to suppression for lack of warnings. Id.
¶ 16 The appropriate test for determining whether a situation involves custodial interrogation is as follows:
The test for determining whether a suspect is being subjected to custodial interrogation' so as to necessitate Miranda warnings is whether he is physically deprived of his freedom in any significant way or is placed in a situation in which he reasonably believes that his freedom of action or movement is restricted by such interrogation. ■
Commonwealth v. Busch, 713 A.2d 97, 100 (Pa.Super.1998) quoting Commonwealth v. Rosario, 438 Pa.Super. 241, 652 A.2d 354, 365-66 (1994) (era banc), appeal denied, 546 Pa. 668, 685 A.2d 547 (1996) (other citations omitted). Said another way, police detentions become custodial when, under the totality of the circumstances, the conditions and/or duration of the detention become so coercive as to constitute the functional equivalent of arrest. Commonwealth v. Ellis, 379 Pa.Super. 337, 549 A.2d 1323, 1332 (1988), appeal denied, 522 Pa. 601, 562 A.2d 824 (1989), citing California v. Beheler, 463 U.S. 1121, 1125, 103 S.Ct. 3517, 3520, 77 L.Ed.2d 1275 (1983).
¶ 17 The factors a court utilizes to determine, under the totality of the circumstances, whether a detention has become so coercive as to constitute the functional equivalent of arrest include: the basis for the detention; its length; its location; whether the suspect was transported against his or her will, how far, and why; whether restraints were used; whether the law enforcement officer showed, threatened or used force; and the investigative methods employed to confirm or dispel suspicions. Busch, 713 A.2d at 101. The fact that a police investigation has focused on a particular individual does not automatically trigger “custody,” thus requiring Miranda warnings. Commonwealth v. Fento, 363 Pa.Super. 488, 526 A.2d 784, 787 (1987).
¶ 18 The record reflects that the suppression court utilized the following definition of “custody” for Miranda purposes:
In order to be “in custody[,]” a person must believe that he is not free to leave, and in order to be considered “interroga*201tion[,]” the questioning by the police must be “expected to, calculated to, or likely to evoke admission.” Commonwealth v. Brantner, 486 Pa. 518, 527, 406 A.2d 1011, 1016 (1979). In order to answer the Constitutional questions that are raised in this motion, therefore, it is first necessary to determine whether a reasonable person in Mrs. Mannion’s situation would have felt free to leave and whether the questioning of the police amounted to interrogation. A person is deemed in custodial interrogation if he is placed in a situation in which he reasonably] believes that his fi-eedom of action is restricted by the interrogation. Commonwealth v. Zogby, 455 Pa.Super. 621, 623, 689 A.2d 280, 282 (1997) ([acknowledging that Pennsylvania’s standard for police conduct is more restrictive than that of the Federal Constitution.)
Trial Court Opinion, 8/19/97, reinstated and corrected 10/3/97, at 6. Since the suppression court’s standard is consistent with the law set out above, the suppression court did not err when it defined custody as it did for purposes of determining whether Mannion’s inculpatory statements were the product of custodial interrogation so as to require Miranda warnings.
¶ 19 The Commonwealth argues that custody is triggered only when the suspect is subject to “restraints comparable to those associated with an arrest,” Appellant’s Brief at 10,15, and supports its argument by reference to cases involving traffic stops.5 As the above discussion reflects, police detentions in Pennsylvania become custodial when, under the totality of the circumstances, the conditions and/or duration of the detention become so coercive as to constitute the functional equivalent of arrest. See Busch, 713 A.2d at 100 and Ellis, 549 A.2d at 1332. Thus, a reviewing court is to consider the particular facts of each case in order to determine whether a detention is custodial. While we agree that the Commonwealth’s articulation of the law is accurate, we do not, however, conclude that what factually is deemed a “restraint comparable to those associated *202■with an arrest” in traffic stop cases is automatically applicable in other factual settings.
¶ 20 The usual traffic stop constitutes an investigative rather than a custodial detention, unless, under the totality of the circumstances, the conditions and duration of the detention become the functional equivalent of arrest. Commonwealth v. Haupt, 389 Pa.Super. 614, 567 A.2d 1074, 1078 (1989). Since an ordinary traffic stop is typically brief in duration and occurs in public view, such a stop is not custodial for Miranda purposes. Commonwealth v. Leib, 403 Pa.Super. 223, 588 A.2d 922 (1991).
¶21 Also, a motorist has certain statutory obligations to stop, to remain at the scene of an accident, and to provide information. A motorist has a statutory duty to bring his vehicle to a stop when a police officer so directs. 75 Pa.C.S.A. § 3733(a). When a motorist is involved in an accident, he has a statutory duty to immediately stop, remain at the scene, and provide certain information. 75 Pa.C.S.A. §§ 3742-44. Thus, a motorist is not in custody for Miranda purposes when his freedom is restricted to the extent of his statutory obligation to remain at the scene and provide required information. See Commonwealth v. Gonzalez, 519 Pa. 116, 124, 546 A.2d 26, 29 (1988).
¶ 22 An ordinary traffic stop becomes “custodial” when the stop involves coercive conditions, including, but not limited to, the suspect being forced into a patrol ear and transported from the scene or being physically restrained. See infra, n. 5. Such coercive conditions constitute “restraints comparable to arrest” so as to transform the investigative nature of an ordinary traffic stop into custodial interrogation. Thus, where a motorist has statutory obligations that necessarily restrict his freedom of action or movement, reliance on traffic stop cases is appropriate to determine what coercive conditions are necessary to transform this type of investigative detention into custodial interrogation. However, where no such statutory obligations exist, reliance on cases involving brief and public stops and statutory obligations is not helpful. In conclusion, whether a person is in custody for Miranda purposes 'must be evaluated on a case-by-case basis with due regard to the particular facts involved.
¶ 23 The Commonwealth next argues that even if the suppression court correctly articulated the definition of custody, the legal conclusions drawn from the facts were incorrect because Mannion’s statements were not the product of custodial interrogation. Following a review of the record, we find merit to the Commonwealth’s arguments.
¶ 24 As noted above, while we are bound by the suppression court’s factual findings which are supported by the evidence, we may reverse the suppression court when it draws erroneous legal conclusions from those factual findings. Williams, 539 Pa. at 71-2, 650 A.2d at 426. Here, the suppression record clearly reflects that custodial interrogation had not occurred when Mannion made her statements. The record reveals that prior to the June 28, 1996 meeting, Trooper Milligan obtained Mannion’s permission before speaking with her. At this time, Mannion not only agreed to meet with the troopers in her home, but she also chose that location. Once the troopers arrived, they informed Mannion that she was not required to speak with them, could refuse to speak at anytime, and could ask them to leave at any time. Mann-ion nevertheless invited the troopers into her home and voluntarily submitted herself to questioning.
¶25 During the meeting, Mannion offered the troopers tea or coffee and moved about freely as she smoked cigarettes. When the telephone rang and interrupted the meeting, Mannion asked permission to answer. At this time, Trooper Sauers informed Mannion that she was free to do as she pleased. Mannion then engaged in a telephone conversation for approximately five minutes. At all times, Mannion was free to move about her home, free to do what she wanted, including taking a telephone call, free of any type of police restraint and free of the fear of imminent arrest. At no time did the troopers search Mannion, remove her from her home, or use any type of restraints. Additionally, the troopers made no show, threat, or use of force. Moreover, Mannion *203herself had stated that she viewed Troopers Milligan and Sauers as neutral and she believed they could help her explain the situation to the Flaxenburgs.
¶ 26 It was not until Mannion stated that she paid French Creek’s electric and postage bills in cash that both troopers doubted her credibility. At this point, Trooper Sauers told Mannion that: he believed she was lying; things were not looking good for her; and she was going to be arrested at some point in time. He then stood up and walked beside Mannion. While standing alongside Mannion, and immediately prior to her confession, Trooper Sauers said in a low voice that he did not believe French Creek would pay its electric bills in cash, that he believed Mannion was lying, and that he thought she took the money to help her children. Even if the police investigation did at that point focus on Mannion, custodial interrogation was not automatically triggered. Ellis, 549 A.2d at 1332. Moreover, the fact that Trooper Sauers spoke in a low voice, in and of itself, fails to evidence any threat of force or coercion. Rather, the uncontradicted testimony of the troopers establishes that Mannion’s statements were gratuitous. In addition, the record reflects no testimony that Mannion indicated she felt intimidated by the troopers or that her freedom was restricted.
¶ 27 Under the totality of these circumstances, Mannion’s conduct was consistent with a willing and cooperative witness. The record does not support the suppression court’s conclusions that Mannion was under arrest or subject to coercion from which she could reasonably believe she was in custody.6 Therefore, we hold that Mannion’s statements were not the product of custodial interrogation, Miranda rights did not attach, and her statements should not have been suppressed.
¶ 28 The dissent asserts that we failed to evaluate important factors relied on by the suppression court. To the contrary, we were quite careful to evaluate whether the court’s findings were supported by the record. Also, the dissent observes that the trial court had the benefit of hearing the testimony of the suppression witnesses firsthand and of observing their demeanor. Yet, we point out that the only suppression witnesses were the two police officers, neither of whom testified that their voices were menacing, or that Mannion did not feel comfortable enough to answer her phone or to ask them to leave. Our record review revealed that the learned court’s conclusions were not supported by the record, despite the opportunity to observe the demeanor of the police officer witnesses. We understand that Mannion was in her sixties and the events took place in her home and we also are sensitive to the way we might feel should these events occur to us in our own homes. Nevertheless, since our review of the record indicates that some of the suppression court’s findings lacked record support, we are not able to reach the dissent’s “inexorable conclusion that Mannion did not feel fine to ask the officers to leave.”
¶ 29 Order reversed and case remanded for a trial. Jurisdiction relinquished.
¶ 30 Judge SCHILLER files a dissenting opinion in which President Judge McEWEN, Judges CAVANAUGH and DEL SOLE join.
. We note that the suppression court's order is dated October 3, 1997, but was entered on the docket on October 6, 1997. For purposes of clarity, we refer to this order as the "order entered October 6, 1997.”
. The Commonwealth has certified in good faith that the suppression order substantially handicaps or effectively terminates its prosecution of this case. This permits appellate review of the suppression order. Commonwealth v. Dugger, 506 Pa. 537, 546-47, 486 A.2d 382, 386 (1985); Pa.R.App.P. 311(d).
. Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966) (a defendant that is subject to custodial interrogation must be advised of his or her constitutional right to remain silent and his or her right to a lawyer in clear and unequivocal language); Commonwealth v. Johnson, 373 Pa.Super. 312, 541 A.2d 332, 336 (1988) (citations omitted) (a person must be informed of her Miranda warnings prior to custodial interrogation by police).
. In its order entered October 6, 1997, the suppression court reinstated its August 19, 1997 order and memorandum opinion, and corrected one word in its August 19, 1997 opinion. The order entered October 6, 1997 also contains a footnote that addresses certain minor arguments raised by the Commonwealth on reargument. The order did not change the reasoning or legal analysis of the suppression court's original August order.
. The Commonwealth relies on the following cases, all of which are traffic-stop cases: Commonwealth v. Gonzalez, 519 Pa. 116, 546 A.2d 26 (1988) (defendant-motorist’s statement made in response to police questioning at accident scene without Miranda warnings held admissible in prosecution for driving under the influence, two counts of involuntary manslaughter, and two counts of homicide by vehicle while driving under the influence because: defendant was not under arrest, defendant’s freedom was restricted only to extent of statutory obligation to stay at scene and provide required information and defendant failed to demonstrate that he was subjected to restraints comparable to those associated with arrest); Commonwealth v. Proctor, 441 Pa.Super. 176, 657 A.2d 8 (1995) (defendant-motorist detained at accident scene for questioning was not in custody for Miranda purposes where: motorist remained at scene for only short time period to allow police officer to complete investigation; motorist was not informed that detention would not be temporary; single trooper questioned defendant; field sobriety test conducted in plain view of passing motorists failed to constitute coercive activity equivalent to station house interrogation; motorist had duty under state law to remain at accident scene and cooperate with police because his freedom of movement was not inhibited in any significant way); Commonwealth v. Leib, 403 Pa.Super. 223, 588 A.2d 922 (1991) (defendant-motorist’s statements not suppressed because noncoercive, temporary detention aspects of ordinary traffic stops are not custody for Miranda purposes even though such stops are seizures within meaning of Fourth Amendment, because they are typically brief, as opposed to prolonged station house interrogation; they commonly occur in public view, an atmosphere far less police dominated than that surrounding the kinds of interrogation at issue in Miranda itself; and therefore, detained motorist’s freedom of action not curtailed to a degree associated with formal arrest) (citing and relying onPennsylvania v. Bruder, 488 U.S. 9, 109 S.Ct. 205, 102 L.Ed.2d 172 (1988)); Commonwealth v. Sullivan, 399 Pa.Super. 124, 581 A.2d 956 (1990) (defendant-motorist not in custody for Miranda purposes when subject to an ordinary traffic stop and not placed under arrest, forced to enter a police patrol car, subjected to coercion, or subject to prolonged questioning); Commonwealth v. Haupt, 389 Pa.Super. 614, 567 A.2d 1074 (1989) (traffic stop constituted investigative detention, as opposed to custodial detention; and, therefore, Miranda warnings not required because basis for detention was traffic violation; stop endured approximately 15 to 20 minutes; location was public street; defendant-motorist not transported; no restraints used; and police officer made no show, threat, or use of force); Commonwealth v. Toanone, 381 Pa.Super. 336, 553 A.2d 998 (1989) (defendant-motorist not entitled to Miranda warnings prior to questioning regarding educational background and request to recite alphabet because motorist not interrogated for unreasonably long period, forced to enter patrol car, or subjected to any form of undue coercion).
. We contrast the instant facts from those in Commonwealth v. Zogby, 455 Pa.Super. 621, 689 A.2d 280 (1997) wherein we affirmed the suppression court’s order granting defendant-appel-lee’s motion to suppress oral statements and physical evidence. Unlike the instant case, in Zogby, we held that defendant-appellee was in custodial detention when a law enforcement officer entered his bedroom, aroused him from a sound sleep, and "advised” or requested him to come downstairs to answer some questions without informing him that he could decline the request. Under the totality of these circumstances, we held that it was highly unlikely that defendant-appellee believed, or that anyone similarly situated would believe, that he could simply turn over and go back to sleep. Therefore, we held that the incriminating statements he thereafter made to the officer without the benefit of Miranda warnings were properly suppressed.
