The state appeals from a pretrial order granting defendant’s motion to suppress the results of a breath test. The issue is whether the arresting officer had probable cause to arrest defendant for driving under the influence of intoxicants (DUII), ORS 813.010. We hold that he did, and reverse.
Shortly before 2:00 a.m. on October 17, 1993, officer Bressler was stopped at the intersection of Park and 3rd Street1 in Corvallis, with his right turn signal activated. He watched defendant’s vehicle, which was beginning to leave the parking lot of a tavern, approach the point at which the lot enters 3rd Street. The vehicle paused for approximately 45 seconds, turned left onto 3rd Street, crossed the two southbound lanes and crossed the center turn lane, all without using turn signals.2 Bressler drove up behind defendant’s car and activated his overhead lights. Defendant turned into a convenience store parking lot and stopped.
When Bressler approached defendant’s vehicle, the driver’s window was rolled down about four inches. A passenger sat in the passenger seat. Bressler asked defendant, who was driving, to roll down his window further. Defendant refused. Bressler smelled an odor of alcohol coming from inside the car. He asked defendant how much he had had to drink and defendant replied that he had not been drinking. Bressler then asked defendant to produce his driver’s license, which defendant did without difficulty. When defendant showed his license, Bressler observed that defendant’s eyes were bloodshot and watery. He asked defendant to get out of the car and defendant refused. Bressler advised defendant of his Miranda rights and the consequences of refusing to perform field sobriety tests. He then repeated his request for defendant to get out of the car. Defendant responded, ‘Td *297rather not,” and told Bressler that he would not get out of the car unless he was under arrest. Bressler arrested defendant.
Bressler took defendant to jail, where he administered an Intoxilizer breath test. The test revealed a blood alcohol content of .09 percent. Defendant was then released from custody. He called a taxi and went to a hospital, where he independently obtained a blood test. The test revealed a .06 percent blood alcohol content. Approximately 74 minutes had elapsed since he had taken the Intoxilizer test.
In a pretrial motion to suppress the breath test results, defendant contested the validity of the stop and the arrest and also contended that he had been denied an opportunity to have an independent blood test performed within a reasonable time. The trial court held that the stop was valid, because of the traffic infractions that defendant had committed,3 and that defendant had been given a reasonable opportunity to obtain an independent blood test. However, the court concluded that Bressler lacked an objective basis for believing that defendant was under the influence of intoxicants when he arrested him. Accordingly, the court suppressed the evidence of the Intoxilizer test.
On appeal, the state argues that Bressler did have probable cause to arrest defendant for DUII, based on his observations that defendant:
“(1) left the parking lot of a tavern in the early morning hours[;] (2) remained stopped at the exit to the parking lot for approximately 45 seconds before exiting onto the street; (3) made an unlawfully wide turn from the parking lot to 3rd Street; (4) had watery and bloodshot eyes; (5) was driving a vehicle emanatingthe odor of alcohol; (6) refused to lower his window more than four inches or so during the stop; (7) told Deputy Bressler he had had nothing to drink; and (8) declined to submit to field sobriety tests, even after he was warned of the consequences of refusal.”
According to the state, “the most important factor [supporting probable cause] in this case was defendant’s refusal to submit to field sobriety tests.”
*298Defendant argues that the administration of field sobriety tests is a search and that there must be probable cause to arrest for DUII before field sobriety tests can be required of a suspect. He contends that the state’s reliance on his refusal to submit to field sobriety tests is misplaced in the light of State v. Nagel, 320 Or 24, 880 P2d 451 (1994).
In Nagel, the Supreme Court held that the administration of field sobriety tests is a search within the meaning of Article I, section 9, of the Oregon Constitution.4 Id. at 31. In order for a search to be constitutionally permissible, the police must have a warrant unless the search falls within one of the recognized exceptions to the warrant requirement. Id. One of those exceptions is “a search conducted with probable cause and under exigent circumstances.” Id. at 31-32. Under Article I, section 9, probable cause has both a subjective and an objective component. An officer must subjectively believe that a crime has been committed and therefore a thing is subject to seizure, and that belief must be objectively reasonable in the circumstances. Id. at 32.
Here, the trial court’s probable cause analysis concluded only that Bressler lacked an objective basis for believing that defendant was driving under the influence of intoxicants. The state argues, and defendant does not seriously contest, that we may infer, from the record before us, that Bressler possessed the requisite subjective belief. We agree that that was a tacit finding of the trial court.
As support for its position that Bressler’s belief was also objectively reasonable, the state relies primarily on defendant’s refusal to submit to the field sobriety tests. That reliance is misplaced, in the light of Nagel.5 As noted above, Nagel held that field sobriety tests are a “search,” within the meaning of the Oregon Constitution, and therefore cannot be *299conducted unless the officer has a warrant or has probable cause and there are exigent circumstances. If refusing to take field sobriety tests was itself a fact that could be used to establish probable cause to administer those tests, citizens’ ability to exercise their constitutional right to be free from unreasonable governmental searches would be profoundly impaired, because if both consent and refusal to consent provided bases for officers to conduct searches, there would be no circumstances under which officers could not search. That result is clearly not allowed by our constitution. Just as the fruits of a search cannot be used, after the fact, to justify a search that has been conducted, a citizen’s refusal to consent to a search, before it takes place, cannot be used to establish the requisite probable cause to conduct the search.
The state contends that, because an individual can consent to a governmental search, and because drivers have impliedly consented to such searches under ORS 813.135, a driver’s refusal to take field sobriety tests is a fact that can give rise to probable cause to arrest that driver for DUII. That approach would allow officers to, in effect, use as “evidence” of guilt a defendant’s “choice” to take or refuse certain field sobriety tests. The Supreme Court has recently held that the government’s use of such a choice as evidence in a DUII prosecution requires a defendant to incriminate himself or herself, in violation of the Oregon Constitution. State v. Fish, 321 Or 48, 893 P2d 1023 (1995).6 Furthermore, it is well established that the act of refusing an officer’s request to search cannot be used to support probable cause. State v. Lavender, 93 Or App 361, 364, 762 P2d 1027 (1988); State v. Wise, 72 Or App 58, 62 n 3, 695 P2d 68 (1985). Accordingly, refusal to consent to field sobriety tests cannot be used to establish probable cause to believe that a defendant is intoxicated.
The only question to be resolved, then, is whether the remaining facts in this case were sufficient to establish probable cause. Several of the facts are neutral, in that they neither *300validated nor refuted Bressler’s belief that defendant was intoxicated: Defendant waited for 45 seconds before entering 3rd Street, see note 2, above, declined to roll down his window further than four inches, denied that he had anything to drink and refused to step out of his vehicle when requested. Two of the facts are exculpatory, in that they tended to disprove the existence of intoxication: Defendant’s speech was not slurred and he had no difficulty producing his driver’s license.
Nevertheless, several facts tended to establish defendant’s intoxication: While leaving a tavern parking lot at 2:00 a.m., defendant committed a traffic infraction and, during the stop that followed, the officer observed defendant’s bloodshot, watery eyes and smelled a strong odor of alcohol emanating from the vehicle.7 We hold that those facts, in combination, were sufficient to establish probable cause that defendant was intoxicated. Accordingly, the trial court erred in granting defendant’s motion to suppress.
Reversed and remanded.
Third Street is a north-south four-lane highway with a center turn lane.
Bressler testified that, although defendant’s left turn signal was on for most of the 45 second wait, defendant turned his signal off before entering 3rd Street. Although under other circumstances that fact could cause one to suspect that defendant’s mental functioning was impaired, here it is a neutral fact. At defendant’s license suspension hearing, Bressler testified that he “assumed” that defendant’s vehicle waited so long before turning because defendant was waiting for the officer to complete the right turn that the patrol car was signaling. Given the relative positions of defendant’s and Bressler’s cars, the rules of the road required that defendant give way to Bressler.
His failure to signal the turn and lane changes was a violation of ORS 811.400(1).
Article I, section 9, provides:
“No law shall violate the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable search, or seizure; and no warrant shall issue but upon probable cause, supported by oath, or affirmation, and particularly describing the place to be searched, and the person or thing to be seized.”
The state submitted its appellate brief in this case a few weeks before the Supreme Court’s decision in Nagel. The state did not submit a memorandum of additional authorities explaining the impact of that decision on this case. ORAP 5.85.
We recognize that the rule announced in Fish applies to refusal evidence that is offered in a DUII proceeding, whereas here, the refusal is being used to establish probable cause. The common denominator, however, is that in both settings a driver’s refusal is incriminating, because it is being used to infer guilt, and that inference is likely to have deleterious consequences for the driver, i.e., arrest or conviction.
Defendant highlights the fact that, because the odor of alcohol was emanating from a vehicle that had two occupants, the officer could not tell if the odor was coming from defendant, his passenger, or both, and, therefore, the odor could not be used to establish probable cause to arrest him for DUII. That argument misses the point. The officer was not required to explore and eliminate all possible alternative explanations for the smell of alcohol in defendant’s vehicle in order for that odor, in combination with the other relevant facts, to give rise to probable cause.
