OPINION
T1 Keith Street appeals from his convietion for driving under the influence of alcohol (DUI), arguing that the trial court erred by denying his motion to suppress evidence. We affirm.
BACKGROUND
T2 On the evening of July 17, 2008, a Salt Lake City police officer was working on a foot patrol assignment in Liberty Park. While the officer was on patrol, a woman with children approached him. She informed him that there was an individual "passed out" in his vehicle in the park and that she believed the individual was intoxicated. She informed the officer that "[slhe was concerned because there was a child in the vehicle and she didn't want a person that ... she believed was intoxicated to drive with the child in the car with him." She described the vehicle and its location in the park.
1 3 The officer approached the vehicle and confirmed that both the vehicle and its occupants matched the descriptions given by the woman. As the officer approached, the vehicle pulled out and passed him, and he flagged it down. The officer did not witness any erratic driving. He spoke with the driver, Street, through the open window. The officer testified that he could smell alcohol, that Street's eyes were bloodshot, and that Street was "acting as if he was intoxicated." After encountering Street, the officer contacted other on-duty officers to conduct field sobriety tests. Street was eventually arrested and charged with DUI.
T4 Street filed a motion to suppress evidence of everything that occurred after the officer stopped Street, including the field sobriety and chemical tests, on the ground that the officer lacked a reasonable suspicion sufficient to stop Street's vehicle. The trial court denied Street's motion to suppress, concluding that the woman's information was sufficient to support a reasonable suspicion. Subsequently, Street entered a conditional guilty plea, see generally State v. Sery,
ISSUE AND STANDARD OF REVIEW
15 Street argues that the trial court erred by denying his motion to suppress because the woman's tip was insufficient to support a reasonable suspicion of DUI. In reviewing motions to suppress evidence in search and seizure cases, we review the trial court's application of the law to underlying factual findings nondeferentially for correctness. See State v. Brake,
ANALYSIS
T6 The protections of the Fourth Amendment "'extend to brief investigatory stops of persons or vehicles that fall short of traditional arrest'" State v. Roybal,
T7 "It is well-established in this state that the articulable facts supporting reasonable suspicion may come from ... external information such as an informant's tip...." State v. Kohl,
T8 Street argues that the woman in this case was not a reliable informant because she did not identify herself by name and the officer did not request any personal information from her. He further argues that the information provided by the woman was not sufficiently detailed because she did not explain to the officer why she believed Street was intoxicated. Finally, he argues that due to the weakness of these two factors, police corroboration of facts suggesting that he was intoxicated was necessary to support a reasonable suspicion.
19 The first two factors, if established, may alone be sufficient to support a reasonable suspicion, so long as they are not contradicted by the officer's personal observations. See Roybal,
I 10 We have previously referred to a "reliability scale" in assessing the reliability of an informant. See Mulcahy,
111 "Anonymous" and "unidentified" are not entirely synonymous in this context. An anonymous tip lacks not only specific identification of the informant, such as a name or contact information, but is also generally devoid of other facts that might indicate the tipster's veracity. See People v. Martinez,
€12 Although the woman in this case was not identified, she was not truly anonymous because the circumstances indicate that she was a reliable citizen-informant. She approached the officer in a public park with her children. She sought nothing in return for her information, and her stated concern was for the safety of the public and the child in Street's car. See generally Kaysville City v. Mulcahy,
113 As to the second Mulcahy factor, although the woman did not provide extensive detail regarding the suspected criminal activity, the detail she did provide was sufficient to support a reasonable suspicion. In the context of reporting a drunk driver, detailed information is generally not required. See Mulcahy,
{14 While the existence of the third Muleahy factor, police corroboration, is not necessary to support a reasonable suspicion, it is relevant to the extent that it strengthens or weakens either the reliability of the tipster or the content of the tipster's information. Cf. Roybal,
T15 Although the officer did not personally witness any actions by Street, such as erratic driving, that would suggest criminal activity, his observations were not inconsistent with the woman's report, which was sufficiently detailed and reliable to sup
CONCLUSION
T16 The woman in this case, although unidentified, was a highly reliable citizen-informant. Furthermore, because citizens are generally assumed to be capable of recognizing intoxication, the woman's report that she believed Street to be intoxicated was sufficiently detailed, even though she did not volunteer the reasoning behind her belief. The officer's personal observations were consistent with the woman's account, and his corroboration of her physical descriptions strengthened her basic reliability. Therefore, the totality of the cireumstances supports the existence of a reasonable suspicion, and we affirm the trial court's denial of Street's motion to suppress.

Notes
. Although the officer noticed that Street's eyes were bloodshot and smelled alcohol on Street's breath after the officer stopped the vehicle, these corroborative observations are not relevant to the totality of the circumstances analysis here because they did not occur until after the vehicle was seized.
