The state appeals a pretrial order suppressing evidence in the prosecution of defendant for driving under the influence of intoxicants (DUII). ORS 813.010. The state assigns error to the trial court’s finding that the officer lacked subjective probable cause to arrest defendant. Because the tried court’s finding was based on an incorrect legal standard, we reverse and remand.
On November 16,1996, Officer Maul cited defendant for driving under the influence of intoxicants (DUII). Defendant filed a motion to suppress any evidence regarding the field sobriety tests (FSTs) and the Intoxilyzer test. At the suppression hearing, Maul testified to the following: At 1:45 a.m., a seemingly high traffic time for DUIIs, Maul noticed defendant driving 15 miles per hour under the speed limit and weaving within his lane. This gave Maul “concern” that defendant was impaired. Defendant then signaled less than 20 feet before turning onto another street. Maul pulled defendant over, intending to cite him for failing to signal 100 feet before a turn and to investigate defendant’s “odd driving.” As Maul approached defendant’s truck, defendant stepped out and “wobbled.” Defendant’s eyes were watery and red, and he looked shocked and confused. Maul explained that defendant’s lack of balance, bloodshot eyes, and apparent confusion indicated that defendant was alcohol impaired. Maul asked defendant to get back in the truck. When defendant had trouble doing so, Maul asked him if he had been drinking, and defendant responded that he had consumed two beers earlier.
At that point, Maul “had some real concerns that [defendant] might have been driving under the influence,” and he asked defendant to come to the back of the truck so they could talk further. Defendant complied and seemed more stable as he got out of the truck; however, defendant’s walk was imbalanced, and he still looked confused. Maul then read defendant his Miranda rights, but he testified that defendant was not under arrest at that time. Maul explained that he “had some real concerns and * * * wanted to give [defendant] an opportunity to either substantiate [Maul’s] *389 concerns or alleviate them.” Maul then asked defendant to perform some FSTs, which defendant refused. Maul testified: “Based on the observations I already did, I placed him under arrest for” DUII. Those observations included “slurred speech, unsure balance, confused, unsure footing, the odd driving, driving too slow, [weaving] within the lane, failing to signal, [defendant’s] confused look, and the fact that [defendant] admitted to consuming some alcohol earlier that night.” Maul described defendant’s level of intoxication as “[o]bvious. I could tell when I put defendant in the car that I thought he was impaired from drinking alcoholic beverages.”
Following defendant’s arrest, he was taken to the police station where he agreed to take an Intoxilyzer test from Officer Powell. Defendant’s test exceeded the legal limit for blood alcohol. During that time, defendant made additional admissions concerning the number of alcoholic drinks he had consumed.
The trial court found both officers credible and made findings of fact consistent with Maul’s testimony. The trial court held that those facts “clearly established an objective basis for Officer Maul having probable cause to believe that defendant was under the influence of the intoxicants.” The court then explained that under
State v. Owens,
On appeal, the state argues that the trial court applied an incorrect rule of law to determine whether Maul had subjective probable cause before defendant refused to perform the FSTs. The state argues that the trial court based its determination on incorrect legal assumptions,
i.e.,
the court was precluded from
inferring
subjective probable cause

from the facts in the record, and the officer had to include “magic words” in his testimony explicitly stating his “belief’ that defendant was intoxicated. Defendant responds that the trial court made a factual finding that is supported by evidence in the record, and we, therefore, are bound by that finding. We review whether the trial court correctly applied the legal principles to the facts.
State v. Davis,
Subjective probable cause means that the officer believes that it is more likely than not that defendant committed an offense.
State v. Wetzell,
The circumstances from which probable cause may be reasonably inferred include the objective facts of defendant’s conduct, the officer’s knowledge at the time, the officer’s expertise or experience, and the conduct of the officer, including the officer’s choices and manner of investigation.

See State v. Belt,
The finding of subjective probable cause is a question of fact to be determined by the totality of the circumstances. Because the trial court’s analysis was predicated on the erroneous presumption that subjective probable cause had to be shown by testimony, we reverse and remand to the trial court with instructions.
State v. Bernson,
Reversed and remanded with instructions for trial court to enter findings on subjective probable cause: If trial court finds that officer had subjective probable cause that defendant was intoxicated before defendant refused to perform field sobriety tests, it shall enter an order denying defendant’s motion to suppress. If trial court finds that officer did not have subjective probable cause, it shall reinstate order of suppression.
Notes
The state argues that an officer’s choice to make an arrest is conduct from which a trial court may infer subjective probable cause. We do not agree with this proposition. If a trial court could infer subjective probable cause from the arrest, we would never need to inquire into subjective probable cause for the arrest.
