¶1Following trial, a jury convicted Erick Pedersen on one count of operating a moving vessel under the influence of alcohol to the extent that it was less safe for him to do so (“boating under the influence” or “BUI”) and three counts of endangering a child by operating a moving vessel under the influence of alcohol. On appeal, Pedersen contends that the trial court erred in denying his motion to suppress the results of the field-sobriety tests, specifically arguing that he was in custody when the tests were conducted for purposes of Miranda v. Arizona
¶2Viewed in the light most favorable to the jury’s verdict,
¶3At that point, the DNR officer asked Pedersen to don a life-vest and step onto the officer’s vessel, so that the officer could conduct field-sobriety tests. Pedersen complied, and thereafter, the officer administered several field-sobriety tests, including the horizontal gaze nystagmus (HGN) test, reciting the alphabet, counting to twenty forward and backward, and a finger dexterity test. Pedersen exhibited signs of impairment after each test, and when the portable alco-sensor test returned a positive result, the officer informed Ped-ersen that he was placing him under arrest for operating a vessel under the influence of alcohol. The officer then read Georgia’s implied consent law, but Pedersen refused to take the state-administered breath test.
¶4Following his arrest, the State charged Pedersen, via accusation, with one count of operating a moving water vessel under the influence of alcohol to the extent that it was less safe for him to do so (“BUI less safe”),
¶5Subsequently, the matter proceeded to a trial before a jury, in which the only evidence presented was the DNR officer’s testimony and the audio/video recording of the officer’s interaction with Peder-sen that evening. And at the conclusion of the trial, the jury found Pedersen guilty on the charges for BUI less safe and endangering a child by operating a moving vessel or personal watercraft under the influence of alcohol. Pedersen then filed a motion for new trial, which the trial court also denied. This appeal follows.
¶6At the outset, we note that when the facts material to a motion to suppress are disputed, “it generally is for the trial judge to resolve those disputes and determine the material facts.”
¶7As noted supra, Pedersen contends that the trial court erred in denying his motion to suppress the evidence garnered as a result of stopping his boat, arguing that he was in custody when the field-sobriety tests were conducted and, thus, should have been advised of his Miranda rights. We disagree.
¶8In Georgia, it is well established that during the course of an investigation, a law-enforcement officer may temporarily detain an individual and that this type of detention does not normally trigger the protections of Miranda,
would cause a reasonable person to believe that he was under arrest — as opposed to being temporarily detained— during an investigation, the officer’s subjective belief that probable cause exists to make an arrest does not determine when the arrest is effectuated until the officer overtly acts so that a reasonable person would believe he was under arrest.21
¶9Applying these principles to this matter, we conclude that the trial court did not err in finding that Pedersen was not in custody for purposes of Miranda at the time the field-sobriety tests were conducted. As previously noted, the DNR officer stopped the pontoon boat because he believed Pedersen was operating the boat at night with its docking lights improperly illuminated such that its navigation lights were not clearly visible to other vessels.
¶10Furthermore, although it is certainly true that Pedersen was not permitted to leave the DNR officer’s vessel during the course of the field-sobriety tests, there is nothing in the officer’s words, all of which were heard in the recording of the encounter, that would cause a reasonable person to conclude that Pedersen was more than temporarily detained pending the outcome of the investigation. In fact, at no time prior to the conclusion of the tests did the officer tell Pedersen that he was under arrest, and he never placed him in handcuffs. Given these particular circumstances, a reasonable person would conclude that the DNR officer was conducting field-sobriety testing for the very purpose of determining whether to take Pedersen into custody. And treatment of this nature cannot be fairly characterized as “the functional equivalent of [a] formal arrest.”
