¶ 1. Defendant appeals the civil suspension of his driver’s license and his conviction for driving under the influence of intoxicating liquor (DUI). Defendant argues that the trial court erred in denying his motion to suppress all evidence obtained after administration of a preliminary breath test (PBT) because the State failed to prove that defendant voluntarily consented to take the PBT. We affirm.
¶ 2. The court found the following facts. At 12:20 a.m., a Vermont state trooper stopped defendant’s vehicle after observing that a rear taillight was out. The entire roadside encounter was video and audio recorded. When the officer approached the vehicle, he observed that defendant’s eyes were “extremely watery,” and there was a strong odor of alcohol coming from the car. The trooper observed an empty beer container right behind the passenger’s seat, and defendant advised that he had consumed one beer after leaving work. The trooper went back to his cruiser and returned with a preliminary breath test machine. He put the machine in front of defendant and told defendant to take the test. He also provided defendant with instructions on how to proceed. The trooper did not ask defendant if he consented to take the test or advise defendant that he had a right to refuse. The court found that defendant did not think he had a choice and therefore provided a sample of his breath. The PBT indicated that defendant’s blood alcohol was above the legal limit. The officer then conducted field sobriety tests. The officer’s affidavit indicates that defendant’s performance was poor and caused the officer to conclude that, in his opinion, defendant’s impairment was “substantial.” Defendant was arrested for DUI and agreed to provide an evidentiary breath sample, which produced a result of .150.
¶ 3. Defendant filed a motion to suppress in the criminal and civil suspension cases. He argued that there were insufficient facts to support administering a PBT and that he did not voluntarily consent to the PBT, and therefore that all evidence obtained thereafter should be suppressed. At the hearing, the recording of the traffic stop was played. Defendant testified that he felt he did *27 not have a choice as to whether to take the PBT. The trooper testified that he did not force defendant to take the PBT, and if defendant had refused he would not have made defendant blow into the machine. On cross-examination, he agreed, however, that it was possible that citizens in defendant’s situation could perceive that they were required to take the PBT. The trooper explained that if he had a reasonable suspicion of DUI from observations of a motorist, then he often administered a PBT before asking someone to exit the vehicle to conduct field sobriety tests.
¶ 4. The trial court made findings and issued its decision on the record. The court concluded that the smell of alcohol, the empty beer container, defendant’s watery eyes, and defendant’s admission to drinking provided a reasonable basis to administer the PBT because they were articulable facts to provide reasonable suspicion of DUI. The court further held that although defendant had a right to refuse the test, the officer was not required to affirmatively notify defendant of this right. As a result, the court did not require the State to prove that defendant voluntarily consented to administration of the test. Therefore, the court denied the motion and entered judgment in the civil suspension case. Defendant entered a conditional guilty plea on the criminal conviction, and now appeals the denial of his motion to suppress.
¶ 5. On appeal from denial of a motion to suppress, we review the trial court’s legal conclusions de novo and will uphold its findings of fact unless clearly erroneous.
State v. Lawrence,
¶ 6. On appeal, defendant argues that the PBT was improperly obtained because the State failed to demonstrate that he voluntarily submitted to the test. According to defendant, because a PBT is a search, law enforcement may administer a test only when there is a reasonable suspicion of DUI based on articulable facts and the suspect has voluntarily consented to giving a breath sample for the PBT.
¶ 7. Defendant is correct that a PBT is a search.
State v. McGuigan,
¶ 8. Instead, defendant contends that in addition to reasonable suspicion, an officer must also obtain defendant’s voluntary consent before administering a PBT. According to defendant, under the totality of the circumstances, he did not voluntarily submit to the PBT. See
State v. Sole,
¶ 9. Our resolution of the constitutional question does not, however, fully determine the case because the administration of a PBT is governed by statute. The relevant statute provides that when an officer “has reason to believe that a person” has committed DUI, then the officer “may request the person to
*29
provide a sample of breath for a preliminary screening test.” 23 V.S.A. § 1203(f). The interpretation of a statute is a question of law that we review de novo.
State v. Eldredge,
¶ 10. We need look no further than the plain language of the statute to conclude that when an officer has a reasonable suspicion of DUI, he may “request” that the suspect provide a breath sample, but not order such participation. This conclusion is in keeping with our prior interpretation of this statutory language, which delineates that drivers may not be forced to comply with a request to take a PBT and have a right to refuse to take the PBT.
McGuigan,
¶ 11. In this case, the court’s unchallenged findings are that the officer did not ask defendant to submit to a PBT. The court found that the officer simply “put the PBT up to [defendant]” and that defendant “was not specifically asked if he would like to take the test.” Because the trooper failed to request that defendant take the test, his actions contravened the statute’s directive. Cf.
McGuigan,
¶ 12. The error, however, is harmless. The basis for probable cause to arrest is detailed in the officer’s affidavit and, in addition to the PBT, includes the officer’s observations of defendant, and the results of the field sobriety tests, which strongly indicated that defendant was impaired. The reasonable suspicion
*30
to conduct the field sobriety tests did not depend on the outcome of the PBT. Just as the officer’s observations — the odor of alcohol, defendant’s watery eyes, the empty alcohol container, and defendant’s admission of drinking — provided reasonable suspicion to request a PBT, they also provided reasonable suspicion to conduct field sobriety tests. See
State v. Gray,
Affirmed.
