OPINION
¶ 1 The Arizona Department of Transportation, Motor Vehicle Division (MVD), appeals from a Pima County Superior Court order vacating the suspension of appellee Wendy Lyn Tornabene’s driver’s license by a MVD administrative law judge (ALJ). This case presents an issue of first impression in Arizona: does the alleged unconstitutionality of a law enforcement officer’s stop of a vehicle invalidate the state’s subséquent suspension of the motorist’s driver’s license, pursuant to A.R.S. § 28-1321, based on the motorist’s refusal to submit to a breath test after having been arrested for driving under the influence of alcohol (DUI)? 1 The ALJ implicitly answered that question in the negative. On review, however, the superior court ruled otherwise, concluding that MVD may not suspend a DUI arrestee’s driver’s license if the underlying stop was illegal. Because we disagree with that conclusion, we reverse the superior court’s order and reinstate the ALJ’s license suspension order.
BACKGROUND
¶ 2 We view the evidence in the MVD administrative record in the light most favorable to sustaining the ALJ’s decision, which “may be set aside only if it is unsupported by competent evidence.”
Ontiveros v. Arizona Dep’t of Transp.,
¶ 3 Ivanoff arrived at Park N’ Save at 7:48 p.m. and positioned his patrol car at the payment booth in front of the vehicle, blocking its exit. Ivanoff then walked toward the passenger side of the vehicle and noted that the driver’s clothes and hairstyle were consistent with the caller’s description and that the car’s engine was running and in drive, although the vehicle was stopped at the booth. As Ivanoff reached the driver-side window, he told the driver he wished to speak with her and asked her to step out of the car. He then noticed a very strong odor of alcohol emanating from her face and mouth, that she appeared confused, that her speech was slurred, and that her eyes were bloodshot and watery. Because Ivanoff recognized those as signs of intoxication, he called TAAP Officer Price to perform field sobriety tests.
¶ 4 Price arrived shortly thereafter and spoke with the driver, who identified herself as Tornabene and consented to undergo *330 some field sobriety tests. Price smelled a strong odor of alcohol on her breath and observed that her speech was slurred, that her eyes were watery and bloodshot, and that she swayed a bit as she stood. Price performed the Horizontal Gaze Nystagmus (HGN) test on Tornabene and noted all six cues of impairment under the test. Torna-bene told Price she would not take any additional tests until she had spoken with her attorney. Price then assisted Tornabene in contacting her attorney by cellular telephone. After speaking with Tornabene, the attorney spoke with Price, inquiring about testing procedures and what would happen if Tornabene refused additional testing. Price informed him that TAAP would decide whether to arrest Tornabene for DUI based on the information they had at that point. When the attorney asked Price to wait until he arrived before conducting any more tests, Price informed him that they were working under a two-hour time limit 3 in which to “obtain some breath, blood or other bodily substance” evidence. The attorney stated that he would come out to meet them, and Price said, “fine.”
¶ 5 Price then spoke with his supervisor, TAAP Sergeant Riley, about the attorney’s request. Riley told Price that because of the time constraints involved in a DUI investigation, Price could not delay the decision whether to arrest Tornabene until her attorney arrived. Based upon his observations and the results of the field sobriety test, Price arrested Tornabene at 8:37 p.m., handcuffed her, and read her the Miranda 4 warnings. He then read her the following statements from an “Admin Per Se/Implied Consent Affidavit” form:
Arizona law requires you to submit to and successfully complete tests of breath, blood or other bodily substance as chosen by the law enforcement officer to determine alcohol concentration or drug content. The law enforcement officer may require you to submit to two or more tests. You are required to successfully complete each of the tests.
If the results of the tests indicate your alcohol concentration is .10 or above or .04 or above in a commercial vehicle, your Arizona driver license/permit or nonresident driving privilege will be suspended for not less than 90 consecutive days.
If you refuse to submit or do not successfully complete the specified tests, your Arizona driver license/permit or nonresident driving privilege will be suspended for 12 months, or for 2 years if there is a prior implied consent refusal, within the last 60 months, on your record. You are, therefore, required to submit to the specified tests.
When Price then asked the question on the form, “Will you submit to the specified tests?,” Tornabene did not respond either yes or no. Instead, she told Price he should be reading this to her lawyer and that she would not answer until the lawyer arrived. At that point, Price read the following statement to Tornabene, as required by the form if the person being questioned “unreasonably delays the completion of test”: “You are not entitled to further delay taking the tests for any reason. Further delay will be considered refusal to submit to the tests.” Riley then drove Tornabene to pretrial services at the Pima County Jail to process Tornabene’s arrest, with the hope that Tornabene would submit to chemical breath testing there.
¶ 6 Wdiile en route to the jail, Tornabene’s attorney called Riley on her cellular telephone and asked to speak with Tornabene. Because Tornabene was in the back seat behind security screening, however, Riley informed the attorney that he would have to talk with her unconfidentially by speaker telephone. 5 Tornabene and her attorney discussed whether she should submit to a *331 breathalyzer test. The attorney advised her to take the test, and Tornabene stated that she would. Riley recommended, and the attorney agreed, that he should go to pretrial services so that Tornabene could be released to him that night.
¶ 7 When Riley and Tornabene arrived at the jail, Riley asked Pima County Pretrial Services staff to send Tornabene’s attorney back to the testing area when he arrived. Staff refused that request, however, explaining that they did not permit any outside persons, including attorneys, into the area where they kept arrested persons. At 9:28 p.m., as Riley prepared to administer the breathalyzer test, Tornabene told Riley that she would not take the test without her attorney present. By that time, the attorney apparently had arrived but had been refused entry to the testing area. Riley informed Tornabene that staff would not allow the attorney into the testing area and asked her again to take the test, but Tornabene repeated that she wanted her attorney present. At 9:36 p.m., just short of two hours after Ivanoff had stopped Tornabene, Riley read and served on Tornabene the order of suspension. About ten or fifteen minutes later, after placing Tornabene in a holding cell, Riley spoke with Tornabene’s attorney, who asked if he could once again try to convince Tornabene to take the test. Riley told him it was too late.
¶ 8 After an evidentiary hearing pursuant to § 28-1321(G) and (K), at which only the three TAAP officers testified, the ALJ entered written findings of fact and suspended Tornabene’s license for twelve months. On Tornabene’s petition for review pursuant to § 28-1321(M), after briefing and oral argument by counsel, the superior court concluded that the police had lacked “probable cause to stop” Tornabene and that she had not refused to take the breathalyzer test. On those two grounds, the court vacated the ALJ’s decision, finding it “arbitrary, capricious and not supported by the evidence.” This appeal by MVD followed.
DISCUSSION
I. Scope and Constitutionality of Administrative License Suspension Hearing
A. Interpretation of Implied Consent Statute
¶ 9 Section 28-1321(A), A.R.S., Arizona’s implied consent statute, 6 provides in pertinent part:
A person who operates a motor vehicle in this state gives consent ... to a test or tests of the person’s blood, breath, urine or other bodily substance for the purpose of determining alcohol concentration or drug content if the person is arrested for any offense arising out of acts alleged to have been committed in violation of this chapter ... while the person was driving or in actual physical control of a motor vehicle while under the influence of intoxicating liquor or drugs. The test or tests chosen by the law enforcement agency shall be administered at the direction of a law enforcement officer having reasonable grounds to believe that the person was driving or in actual physical control of a motor vehicle in this state ... [wjhile under the influence of intoxicating liquor or drugs.
If a motorist who has been arrested for DUI refuses to submit to or unreasonably delays testing, the law enforcement officer may serve an order of suspension on the motorist, who then can request an administrative license suspension hearing to review that order. § 28-1321(D), (G), (K). Section 28-1321(K) limits the scope of such hearing to “only the issues of whether:”
1. A law enforcement officer had reasonable grounds to believe that the person was driving or was in actual physical control of a motor vehicle in this state either:
(a) While under the influence of intoxicating liquor or drugs.
(b) If the person is under twenty-one years of age, with spirituous liquor in the person’s body.
2. The person was placed under arrest.
3. The person refused to submit to the test.
*332 4. The person was informed of the consequences of refusal.
§ 28-1321(K)(1) through (4).
See also Sherrill v. Department of Transp.,
¶ 10 After the administrative license suspension hearing in this ease, the ALJ found that' TAAP had had reasonable grounds to believe that Tornabene had been driving while under the influence of intoxicating liquor or drugs; that she had been arrested and had been requested to submit to a breathalyzer test; that she had been warned that refusal to submit to or failure to successfully complete the test would result in suspension of her driver’s license for twelve months; and, that she had refused to submit to the test. Consequently, the ALJ suspended Tornabene’s license for twelve months. § 28-132KB).
¶ 11 On review, the superior court vacated the ALJ’s order. Citing
State v. Altieri,
¶ 12 MVD contends the superior court erroneously considered whether TAAP’s stop of Tornabene’s vehicle had been lawful, arguing that § 28-1321(K) expressly limits the scope of issues for administrative review. Tornabene counters that the validity of the stop was necessarily part of the superior court’s review, asserting that under the Fourth Amendment to the United States Constitution, “reasonable grounds to believe a person was driving while under the influence means reasonable suspicions [sic] for the stop and probable cause for the arrest.”
7
Whether the superior court erred in considering the legality of the stop as a basis for vacating the ALJ’s suspension order is a question of law that involves statutory interpretation and constitutional issues that are subject to our de novo review.
In re United States Currency in the Amount of $315,900.00,
¶ 13 “Our primary goal in interpreting statutes is to discern and give effect to legislative intent.”
Hobson v. Mid-Century Ins. Co.,
¶ 14 Section 28-1321(K) expressly and clearly states that the scope of an administrative license suspension hearing “shall include only the issues” set forth therein, which do not include any issues relating to the validity of the law enforcement officer’s stop of the motorist’s vehicle. As MVD points out, this court stated in
Owen:
“There
*333
is no requirement under the implied consent statute that the arrest be a valid arrest or that [the arrestee] be convicted for the offense.”
¶ 15 Even if § 28-1321(K) were not clear, other factors support MVD’s argument. “The purpose of the implied consent law is to remove from Arizona highways those drivers who may be a menace to themselves and others because of intoxication.”
Sherrill,
¶ 16 Thus, the unambiguous language of § 28-1321(K), which limits the scope of the hearing to “only the [four] issues” prescribed therein, combined with the obvious spirit, purpose, context, and effect of the implied consent statute,
see Norgord,
establish a clear legislative intent to limit the issues for administrative review, not expand them to include consideration of the constitutional validity of the investigatory stop leading to a criminal DUI arrest. As our supreme court has stated, a civil license suspension proceeding for a DUI arrestee’s refusal of testing is “separate from and unrelated to” a criminal prosecution for DUI, and the “outcome of one proceeding usually will not have any effect on the outcome of the other.”
Sherrill,
¶ 17 Accordingly, we hold that the validity of an investigatory stop leading to a DUI arrest is outside the proper scope of an administrative license suspension hearing under § 28-1321(K). We find persuasive support for that conclusion in several out-of-state cases in which similar statutes have been construed.
See, e.g., Fishbein v. Kozlowski,
¶ 18 In contrast, and we think unwisely, other courts have superimposed on their license suspension statutes a requirement that the underlying stop be lawful, even when the statutes contained no such condition.
See, e.g., People v. Krueger,
B. Fourth Amendment Considerations
¶ 19 Of course, a statute cannot circumvent a firmly established constitutional right.
See In re the Amount of $315,900.00,
¶20 Tornabene contends, however, that the Fourth Amendment precludes an administrative license suspension absent “a showing of reasonable suspicion for the stop,” even when the implied consent statute requires no such showing. We disagree. As noted above, § 28-1321(K) does not expressly require “a showing of reasonable suspicion for the stop” as a prerequisite for administrative suspension of a DUI arrestee’s license. To judicially engraft that requirement into the statute, in our view, would be appropriate only if the Constitution compels us to do so.
¶ 21 Tornabene correctly asserts that the Fourth Amendment applies to “all vehicle stop situations,” whether ultimately leading to criminal or civil proceedings. “[T]he fourth amendment applies to
any
governmental action, not just one arising out of possible criminal activity,” including “[shopping an automobile and detaining its driver to serve a traffic citation.”
State v. Boudette,
¶ 22 Violation of the Fourth Amendment, however, does not invariably preclude the use of evidence derived from the unconstitutional conduct. Rather, the appropriate sanction, if any, for a Fourth Amendment violation depends on the nature of the proceeding in which the illegally obtained evidence will be used and the policy considerations that weigh in favor of or against exclusion of that evidence in such proceeding. As the Missouri court in
Riche
observed, “[t]he United States Supreme Court has repeatedly held that the use of evidence obtained in violation of the fourth amendment does not violate the Constitu
*335
tion,” depending on the nature of the proceedings.
¶ 23 Thus, assuming arguendo that TAAP lacked reasonable suspicion under the Fourth Amendment to justify their stop of Torna-bene’s vehicle based on an anonymous tip uncorroborated by independent observations by the police,
see Altieri,
9
suspension of her license under § 28-1321(K) would not necessarily be invalid on that basis unless the exclusionary rule were applied to the civil license suspension proceeding. Neither the United States Supreme Court nor any Arizona court has applied the exclusionary rule in a purely civil proceeding as a remedy for violation of the Fourth Amendment.
See Pennsylvania Bd. of Probation & Parole v. Scott,
¶ 24 “The exclusionary rule ‘is a judicially created remedy designed to safeguard Fourth Amendment rights generally through its deterrent effect.’”
State v. Fisher,
¶ 25 Evidence obtained in violation of the Fourth Amendment would be inadmissible in criminal DUI proceedings.
See Wysocki,
¶ 26 Thus, exclusion of evidence from the license suspension hearing would have little deterrent value as compared to the benefit of having otherwise reliable evidence that a motorist has been driving while intoxicated available to the ALJ. Moreover, applying the exclusionary rule in the administrative license suspension context would “unnecessarily complicate and burden” the proceeding, which is designed primarily to focus on the issue of whether the motorist was operating a vehicle under the influence of intoxicants.
Powell,
¶ 27 We disagree with the superior court’s statement that, “to hold [that probable cause is not required to stop a motorist under the implied consent statute] would allow the State virtually the unlimited right to stop citizens and force them to take a breathalyser test for any reason or for no reason at all.” First, law enforcement officers are only required to have a reasonable, artie-ulable suspicion of criminal activity, not the higher standard of probable cause, before making an investigatory stop.
See Altieri,
¶ 28 The record does not reflect, nor are we aware of, any cases or statistical studies that suggest a pattern of police misconduct with respect to DUI stops. The prospect of officers knowingly stopping vehicles, without reasonable suspicion of criminal activity, for the purpose of seeking to suspend motorists’ driver’s licenses if they refuse to submit to BAC testing is remote at best. Indeed, the United States Supreme Court has made it clear that random stops of vehicles absent some articulable and reasonable suspicion of wrongdoing are unconstitutional.
See Delaware v. Prouse,
¶29 Review of the ALJ’s decision, both on appeal and at the superior court level, is limited to whether that decision was “arbitrary, capricious, or an abuse of discretion.”
Edwards v. Arizona Dep’t of Transp.,
¶30 Competent evidence, including the officers’ observations after the stop and the results of the HGN test, supported the ALJ’s finding that TAAP had reasonable grounds to believe that Tornabene had been driving under the influence of intoxicants.
See Pearson v. Motor Vehicle Division,
II. Refusal to Submit to Testing
¶ 31 MVD bore the burden of establishing by a preponderance of the evidence that Tornabene refused to undergo chemical breath testing.
See Sherrill,
¶ 32 We first note that our supreme court has consistently rejected the proposition that a motorist who faces civil license suspension is entitled to assistance of counsel in deciding whether to submit to chemical breath testing.
See State v. Juarez,
¶ 33 Even so, the record reflects that TAAP gave Tornabene two opportunities to consult with her attorney before requesting that she submit to the test at the jail. In addition, Tornabene did not ask to “see and speak” with her attorney at the jail, as the superior court found, but rather requested his
presence
during the test. As the ALJ correctly ruled, because Arizona motorists who face civil license suspension proceedings have no right to consult with counsel about whether to submit to breath testing, it follows that they have no right to the presence of counsel during testing. Moreover, in view of the non-testimonial nature of chemical breath testing, even criminal suspects are not entitled to presence of counsel during the test.
See Campbell,
*338 ¶ 34 The record supports the ALJ’s finding that Tornabene refused to submit to testing. Before arriving at the jail, TAAP had advised her that unreasonable delay in taking the test would be deemed a refusal. Although Sergeant Riley did not oppose the presence of Tornabene’s attorney during testing, jail regulations apparently prevented that. When told that it would not be possible for her attorney to be present during her test, Tornabene again stated that she was unwilling to undergo testing without him.
¶ 35 An arrested motorist is deemed to have refused to submit to testing when his or her conduct “is such that a reasonable person in the officer’s position would be justified in believing that such motorist was capable of refusal and manifested an unwillingness to submit to the test.”
Campbell,
¶ 36 We are unpersuaded by Tornabene’s further contention that she was confused about her right to counsel relating to chemical breath testing in light of the
Miranda
warnings she had received and her knowledge that her attorney was attempting to meet with her. She argues that, under these circumstances,
Caretto
and
Gaunt v. Motor Vehicle Division,
¶37 Although TAAP attempted to facilitate as much communication as possible between Tornabene and her attorney, both at the arrest site and on the way to the jail, jail regulations prevented the attorney’s presence at her testing. Tornabene was aware of that before Riley asked her to submit to testing for the last time. Tornabene had already been warned that she was not entitled to further delay testing “for any reason,” and that “[f]urther delay will be considered refusal to submit to the tests,” yet she again stated that she would not take the test unless her attorney was present. 12 The record does not support Tornabene’s claim of confusion, and we find Gaunt and Caretto inapposite.
DISPOSITION
¶ 38 We reverse the superior court’s order and reinstate the ALJ’s order that suspended Tornabene’s driver’s license.
Notes
. In
Pinedo v. Arizona Department of Transportation,
. TAAP Officer Price testified that he believed the caller may have been a Southwest Airline employee.
. Price apparently was referring to A.R.S. § 28-1381(A)(2), which currently criminalizes operating a motor vehicle if a person "has an alcohol concentration of 0.08 or more within two hours of driving.” At the time of Tomabene’s arrest in September 2000, that statute required an alcohol concentration of 0.10 or more. See 2000 Ariz. Sess. Laws, ch. 4, § 2.
.
Miranda v. Arizona,
. Tornabene does not raise as an issue the lack of confidentiality during the second telephone consultation with her attorney.
. Section 28-1321 was formerly numbered A.R.S. § 28-691.
. Although Tornabene’s counsel questioned the TAAP officers at the license suspension hearing about the circumstances surrounding the stop, we note that Tornabene did not specifically raise or argue any Fourth Amendment issues in the administrative proceedings before the ALJ. Her failure to do so arguably waived those issues.
Pavlik v. Chinle Unified Sch. Dist. No. 24,
. Tornabene does not contend TAAP lacked probable cause to arrest her for DUI. But assuming the requisite showing of "reasonable grounds” under § 28-1321(K)(l) is equivalent to a probable cause standard,
see Pearson v. Motor Vehicle Division,
. The parties disagree about whether TAAP had reasonable suspicion to stop Tomabene’s vehicle under the principles set forth in Altieri. We do not address that issue, however, because we have already determined it is outside the statutory scope of an administrative license suspension hearing. And, as discussed below, resolution of that issue is not constitutionally required in this context.
. Although other jurisdictions have reached a different conclusion, in our view those courts gave undue weight to the additional deterrent effect that they perceived application of the ex-elusionary rule in this context would provide.
