delivered the opinion of the court:
Defendant, Tracy E. Rozela, appeals from an order of the circuit court of Du Page County denying her petition to rescind the statutory summary suspension of her driver’s license, pursuant to section 11— 501.1 of the Illinois Vehicle Code (Vehicle Code) (625 ILCS 5/11 — 501.1 (West 2002)), for driving under the influence of alcohol. We affirm.
FACTS
Only Sergeant Kevin Driscoll of the Naperville police department testified at the hearing on defendant’s petition to rescind the statutory summary suspension. Driscoll had been a police officer for 19 years and was trained in the use of field tests for intoxication and in the use of portable breath tests (PBTs). Driscoll had been trained as an instructor in the use of field sobriety tests and was certified as a Breathalyzer operator.
At 12:54 a.m. on September 12, 2002, Driscoll was in his squad car at a gas station in Naperville. Defendant’s car drove past him, and Driscoll estimated that her speed exceeded the 25-mile-per-hour limit. Driscoll activated his radar, which disclosed that defendant was traveling at 37 miles per hour. Driscoll followed defendant’s car and activated his emergency lights after observing it weave twice across the lane dividing line. Defendant turned right onto a street that ran one way in the opposite direction. After defendant curbed her car, Driscoll approached and saw that defendant’s eyes were glassy and bloodshot. Driscoll smelled a strong odor of alcohol on defendant’s breath. Defendant explained that she drove erratically because she was unfamiliar with the area and she was upset by a recent argument with her boyfriend. She admitted drinking a couple of beers at a local tavern that evening.
Driscoll administered the horizontal gaze nystagmus test. The test involves evaluating six points, and defendant failed at every point. However, defendant passed three other field sobriety tests: the one-leg stand test, the walk-and-turn test, and the recite-part-of-the-alphabet test. Defendant’s successful completion of the three tests did not affect Driscoll’s opinion that she was under the influence of alcohol. He believed that a failure of a sobriety test proves a person’s intoxication but successful completion of a test proves nothing.
On direct examination, defense counsel asked Driscoll whether he asked defendant to submit to a PBT. Driscoll testified that he had done so and that defendant complied. There was no evidence that defendant’s submission to the test was involuntary. On cross-examination, Driscoll testified that he used a calibrated, certified Intoximeter Alcosensor III, which reported a blood-alcohol concentration of .126. Defense counsel objected to the admission of the test results, and the court overruled the objection.
Driscoll testified that he arrested defendant for driving under the influence (DUI) and transported her to the police station, where a Breathalyzer test reported a blood-alcohol concentration of .109. The Secretary of State suspended defendant’s driving privileges for three months.
The trial court found Driscoll’s testimony credible and concluded that defendant had not established a prima facie case for rescission of the suspension of her driving privileges. Emphasizing that defendant had a right to refuse to take the PBT without penalty, the court stated that Driscoll was authorized to use the test as a tool to further investigate his reasonable suspicion that defendant had operated a vehicle while under the influence of alcohol. The court denied the petition to rescind the suspension but issued a judicial driving permit for defendant to travel to work and school. Defendant’s timely appeal followed.
ANALYSIS
In her brief, defendant mistakenly states that this court has jurisdiction to consider her appeal under Supreme Court Rule 604(a)(1) (188 Ill. 2d R. 604(a)(1)). Rule 604(a)(1) applies only to appeals filed by the State. However, a trial court’s decision to grant or deny a petition to rescind a summary suspension is treated as a final order in a civil matter, which is appealable under Supreme Court Rule 303 (155 Ill. 2d R. 303). People v. O’Connor,
On appeal, defendant argues that (1) section 11 — 501.5(a) of the Vehicle Code (625 ILCS 5/11 — 501.5(a) (West 2002)), which authorizes PBTs, is unconstitutional; (2) Officer Driscoll lacked reasonable suspicion to ask defendant to submit to the PBT; and (3) the results of the test were inadmissible because the State failed to establish an adequate foundation. Defendant based her petition to rescind on the assertion that there were no reasonable grounds to arrest her for DUI. See 625 ILCS 5/2 — 118.1(b) (West 2002). We initially note that an arrest requires “reasonable grounds” or “probable cause,” but a traffic stop requires only “reasonable suspicion,” which is a distinctly different term. People v. Rush,
A hearing on a petition to rescind the statutory summary suspension of driving privileges is a civil proceeding. The petitioner has the burden of providing a prima facie case for the rescission. People v. Smith,
The State contends that, because the trial court assessed Driscoll’s credibility before entering judgment, we should reverse the court’s ruling only if it is against the manifest weight of the evidence. Defendant responds that a de novo standard of review applies. We defer to the trial court’s findings of fact regarding Driscoll’s credibility, and we will reverse those findings only if they are against the manifest weight of the evidence. See Rush,
Defendant initially contends that section 11 — 501.5(a) of the Vehicle Code, which authorizes portable breath testing, is unconstitutional because it “allows police to obtain a breath sample without probable cause.” The State argues that (1) the exclusionary rule of the fourth amendment does not apply to statutory summary suspension proceedings because they are civil rather than criminal and (2) defendant waived any fourth amendment claim when she consented to the PBT under the statute. Defendant responds that the State waived these defenses by failing to raise them in the trial court. The waiver rule is binding on the parties but not on this court (see People v. Hamilton,
A statute is presumed constitutional. The party challenging the statute bears the burden of demonstrating its invalidity. People v. Malchow,
In People v. Krueger,
“Although the State characterizes the issue in this case as whether to apply the exclusionary rule to a civil summary suspension proceeding, we believe that the real question before us is whether the statute affirmatively authorizes the Secretary of State to suspend a motorist’s license on the basis of a search which itself is the product of an unauthorized arrest. The Secretary’s power to impose a summary license suspension is derived from the statute, and we decline to read the statute as, in effect, authorizing unconstitutional arrests or searches and the imposition of new deprivations based on those unconstitutional arrests or searches.” Krueger,208 Ill. App. 3d at 904-05 .
This court expressly held that “the arrest required by the implied-consent statute must be a lawful arrest” for a summary suspension to be valid. Krueger,
We next turn to defendant’s argument that the implied-consent law unconstitutionally authorizes a PBT without the existence of probable cause. Section 11 — 501.5(a) provides as follows:
“If a law enforcement officer has reasonable suspicion to believe that a person is violating or has violated Section 11 — 501 or a similar provision of a local ordinance, the officer, prior to an arrest, may request the person to provide a sample of his or her breath for a preliminary breath screening test using a portable device approved by the Department of State Police. The person may refuse the test. The results of this preliminary breath screening test may be used by the law enforcement officer for the purpose of assisting with the determination of whether to require a chemical test as authorized under Sections 11 — 501.1 and 11 — 501.2, and the appropriate type of test to request. Any chemical test authorized under Sections 11 — 501.1 [concerning statutory summary suspensions and implied-consent] and 11 — 501.2 [concerning admissibility of chemical test results in DUI prosecutions] may be requested by the officer regardless of the result of the preliminary breath screening test, if probable cause for an arrest exists. The result of a preliminary breath screening test may be used by the defendant as evidence in any administrative or court proceeding involving a violation of Section 11 — 501 or 11 — 501.1.” (Emphasis added.) 625 ILCS 5/11 — 501.5(a) (West 2002).
Section 11 — 501.5(a) permits an officer to conduct a PBT only if (1) the officer has reasonable suspicion that the suspect has committed DUI and (2) the suspect consents to the test. The “reasonable suspicion” standard of section 11 — 501.5(a) is the same that applies to traffic stops generally. Because a vehicle stop constitutes a seizure of the vehicle’s occupants, such a stop is subject to the fourth amendment’s requirement of reasonableness. People v. Moore,
Generally, neither a warrant nor probable cause is required to validate a search made with consent under the fourth amendment. People v. Steinberg,
We next consider defendant’s claim that Officer Driscoll lacked reasonable suspicion to request her submission to the PBT. A police officer may make a valid traffic stop where the officer is able to point to specific and articulable facts which, when taken together with the rational inferences therefrom, reasonably warrant the stop of the defendant’s vehicle. Generally, a traffic violation provides a sufficient basis for a traffic stop. Hood,
Officer Driscoll testified that he observed defendant violate three traffic laws before he stopped her vehicle. Defendant exceeded the speed limit, crossed the lane dividing line twice without signaling, and drove the wrong way on a one-way street. Defendant told Driscoll that a recent argument with her boyfriend had upset her, but she did not otherwise explain her erratic driving. Cf. Rush,
When defendant exited the car, she admitted to drinking that evening at a nearby tavern. Driscoll detected a strong odor of alcohol on her breath and saw that her eyes were glassy and bloodshot. Moreover, defendant failed the horizontal gaze nystagmus test. Despite this quantum of evidence, defendant argues that her successful completion of three other roadside sobriety tests should have dispelled Driscoll’s suspicion that defendant had committed DUI. We disagree. Driscoll pointed to specific and articulable facts which, when taken together with the rational inferences therefrom, suggested that defendant had committed DUI. See Hood,
Defendant next argues that, even if Driscoll had reasonable suspicion to conduct the PBT, the State may not introduce PBT results in summary suspension proceedings. Section 11 — 501.5 allows the State to use a PBT, like other field sobriety tests, to establish that probable cause exists to arrest for DUI. However, the State may not introduce the results of a PBT in its case in chief in a criminal prosecution for DUI. People v. Rose,
“[T]he results of a PBT are admissible on the issue of probable cause. Since the purpose of a PBT is to aid a police officer in determining the existence of probable cause, the results of the PBT must be admissible in a proceeding where that determination is challenged. Probable cause exists where the facts and circumstances known to the arresting officer are sufficient to warrant a man of reasonable caution to believe an offense was committed. People v. Bulman,212 Ill. App. 3d 795 ,571 N.E.2d 850 (1991). Section 11— 501.5 allows an officer to consider PBT results as one of those ‘facts and circumstances.’ Therefore, when the issue is the correctness of the officer’s probable cause determination, he must be allowed to demonstrate the bases for his belief, including PBT results. To hold otherwise renders the statute ineffectual. When the language of a statute permits two constructions, one of which would make an enactment absurd and illogical, while the other renders it reasonable and sensible, the construction which leads to an absurd result must be avoided. People v. Stanciel,153 Ill. 2d 218 ,606 N.E.2d 1201 (1992).” Davis,296 Ill. App. 3d at 928-29 .
Davis involved a motion to quash the arrest and suppress evidence, and this case involves a petition to rescind a statutory summary suspension. However, we conclude that the distinction does not preclude reliance upon Davis, because in each case, the motorist challenges the arresting officer’s probable cause determination. In agreement with Davis, we hold that section 11 — 501.5 of the Vehicle Code permitted the State to introduce the results of the PBT to support Officer Driscoll’s conclusion that he had probable cause to arrest defendant for DUI.
Defendant next argues that the State failed to establish a foundation for the results of the PBT and that such a deficiency bars the State from introducing the test results at a hearing on a petition to rescind a summary suspension of driving privileges. We are unaware of an Illinois case that addresses either issue squarely. However, in People v. Orth,
We note that the Appellate Court, Fifth District, has explained the legal significance of the relative accuracy of PBTs and Breathalyzer testing as follows:
“[C]hemical test results are admissible [in the State’s case in chief in criminal DUI prosecutions] only if the State can show that the instruments used to conduct these tests complied with all the proper statutory and regulatory standards outlined in section 11— 501.2 of the Illinois Vehicle Code [citation], [Citations.] PBT instruments (unlike Breathalyzers) do not meet these stringent requirements for admissibility and, thus, neither do the results.” People v. Brooks,334 Ill. App. 3d 722 , 727 (2002).
Further:
“Breathalyzer machines do not inherently suffer from the same scientific uncertainty that affects PBT machines. The admissibility of Breathalyzer test results is well established, and therefore, to prove intoxication, the prosecution may utilize both the test results and the refusal to take the test.” Brooks,334 Ill. App. 3d at 729 .
Brooks instructs that PBT instruments are less accurate than Breathalyzers and, therefore, the State may not introduce in a criminal DUI prosecution PBT results or the defendant’s refusal to submit to a PBT. Brooks,
Although Orth involved the results of a Breathalyzer rather than a PBT, we consider the case to be instructive because, like this case, it addressed a foundational challenge to blood-alcohol chemical testing in the context of a petition to rescind a summary suspension of driving privüeges. The court held that “once the motorist has made a prima facie case that the breath test result [under section 11 — 501.2(a) of the Vehicle Code (111. Rev. Stat. 1985, ch. 95x/2, par. 11 — 501.2(a) (now 625 ILCS 5/11 — 501.2(a) (West 2002)))] did not disclose a blood-alcohol concentration of 0.10 or more, or that the test result did not accurately reflect his blood-alcohol concentration, the State can only avoid rescission by moving for the admission of the test into evidence and laying the required foundation.” Orth,
Here, defendant did not testify at the rescission hearing and has not set forth any “circumstance which tends to cast doubt on the test’s accuracy.” Orth,
For the preceding reasons, the judgment of the circuit court of Du Page County is affirmed.
Affirmed.
