Dеfendant-appellant Harry Medcalf was charged with speeding and operating a motor vehicle while under the influence of alcohol. The Marietta Municipal Court denied appellant’s motion to suppress the results of a breath-alcohоl test, and appellant subsequently entered pleas of no contest to both charges. The court found appellant guilty, and appellant appeals his conviction for operating a motor vehicle while under the influence of alcohоl.
Appellant assigns the following error:
“The trial court erred in denying the defendant’s motion to suppress the results of a breath-alcohol test.”
At approximately 1:40 a.m. on October 1, 1994, an officer of the City of Marietta Police Department observed appellant driving at the rate of fifty-onе miles per hour where the speed limit was thirty-five miles per hour. When the *144 officer stopped appellant, appellant attempted to parallel park between automobiles along the side of the street. Appellant drove forward into а parking space and struck the parked vehicle in front of him. There was no damage to either appellant’s car or the car parked in front of him. When appellant turned off his automobile, he left the back portion of his automobile extending into the roadway.
While advising appellant of the speeding violation, the officer smelled the odor of alcohol. Appellant admitted that he had consumed “a couple of beers.” The officer then asked appellant to step onto the sidewalk so that the officer could conduct field sobriety tests.
The first test was the horizontal gaze nystagmus test. The officer testified that appellant did “fairly well.” The second test was to walk a straight line, and appellant used his arms a little for balance and swayеd slightly. Appellant then performed the finger-to-nose test without fault. Finally, the officer asked appellant to stand on one leg and extend the other leg straight out about six inches up. For the last eight seconds, appellant raised his arms and hopped to mаintain his balance.
Based upon all of the officer’s observations, the officer placed appellant under arrest for operating a vehicle under the influence of alcohol and transported him to the Marietta City Police Departmеnt. At the police station, the officer asked appellant to perform additional sobriety tests. Appellant swayed slightly on the balance test, in which he was required to bend over forwards and backwards. Appellant then successfully completed the walking-a-white-line test, turning test, and finger-to-nose test. The officer concluded that appellant performed the tests at the station much better than the tests at the scene. The officer 'testified that appellant was orderly and cooperative and that he understood the instructions well. Nevertheless, the officer still believed that appellant was under the influence of alcohol.
After the sobriety tests, another officer asked appellant to take a breath test and notified him of the consequenсes of refusing to take the test. Appellant consented to take the test and the result was .119 gram of alcohol per two hundred ten liters of breath. The officer then charged appellant with operating a motor vehicle under the influence of alсohol in violation of R.C. 4511.19(A)(1) and (3). 1
*145 Appellant filed a motion to suppress the results of the breath test on the grounds that the officer did not have probable cause to administer the breath test. At the hearing on this motion, the trial court first noted the officer’s credibility and thе court’s intention to accept “his testimony at full face value.” The trial court then determined that the officer had probable cause to arrest appellant for operating a motor vehicle under the influence of alcohol. The court stated that it is probably not unusual for someone being stopped by the police to be distracted and park poorly. Regardless of that fact, appellant’s poor parking attempt, the odor of alcohol, appellant’s marginal pеrformance on the field sobriety tests, and appellant’s admission to drinking at least two beers provided the officer with probable cause to arrest.
The trial court next addressed the events that occurred after appellant arrived at the pоlice station, which the court referred to as “the real issue.”
“[T]he indications were, again, very credible testimony from the patrolman that he did very well on those field sobriety tests, on-station. Now, that could be because it was, uh, a more well-lit space, uh, weаther conditions, better, you know, you were inside versus outside, things of that nature. * * *
“It is this court’s opinion that [the officer] had the right to continue his .investigation to its conclusion since he had enough information at the scene to make the arrest.
“The conclusion of the investigation would be the ultimate chemical test which was administered, therefore, the court finds that the defendant’s constitutional rights have not been violated, the officer did not have to stop his investigation, uh, upon administration of the second set of sobriety evaluаtions, and the court is going to deny the motion to suppress.”
Subsequently, the trial court filed an entry denying the motion.
In appellant’s assignment of error, he contests the trial court’s denial of his motion to suppress the results of the breath-alcohol test. When considering a motion to suppress, the trial court assumes the role of the trier of fact and is therefore in the best position to resolve factual questions and evaluate the credibility of the witnesses.
State v. Mills
(1992),
Appellant does not contest the propriety of the officer’s initial stop of his vehicle or the officer’s decision to administer the field sobriety tеsts. Rather, appellant asserts that once he passed all of the sobriety tests given at the station, the officer no longer had probable cause to administer the breath-alcohol test. Appellant cites
Xenia v. Wallace
(1988),
Appellant anаlogizes this situation to the requirement that reasonable suspicion must exist for the duration of an investigative stop. See
State v. Robinette
(1995),
Appellee counters that appellant is trying to use postarrest evidence to' negate probable cause at the time of arrest. Appellee’s concentration on the time of the arrest is proper. See
State v. Chelikowsky
(Aug. 18, 1992), Pickaway App. No. 91CA27, unreported
R.C. 4511.191(A) governs the administration of breath tests and provides in relevant part as follows:
*147 “Any person who operates a vehicle upon a highway or any public or private property used by the public for vеhicular travel or parking within this state shall be deemed to have given consent to a chemical test or tests of his * * * breath * * * for the purpose of determining the alcohol * * * content of his * * * breath * * * if arrested for operating a vehicle while under the influence of alcohol * * *. The chemical test or tests shall be administered at the request of a police officer having reasonable grounds to believe the person to have been operating a vehicle upon a highway or any public or privatе property used by the public for vehicular travel or parking in this state while under the influence of alcohol * *
R.C. 4511.19(D)(1) provides that evidence of the concentration of alcohol in a person’s breath as shown by a chemical analysis of the breath within twо hours of the alleged violation may be admitted in any criminal prosecution for a violation of R.C. 4511.19.
The propriety of the administration of the breath-alcohol test is therefore dependent upon the propriety of the arrest. Before an offiсer can arrest an individual, the officer must have probable cause to believe that the individual has committed a crime.
State v. Timson
(1974),
Probable cause exists where there is a reasonable ground of suspicion, supported by circumstances sufficiently strong in themselves to warrant a cautious person in the belief that an individual is guilty of the offense with which hе or she is charged.
Huber v. O’Neill
(1981),
In this case, the totality of the circumstances establishes probable cause. Appellant was initially stopped for speeding. He had difficulty parking, and the officer noted that he smelled the odor of an alcoholiс beverage. Appellant admitted that he had consumed “a couple of beers.” Additionally, appellant did not perform well on the field sobriety tests. The lawful stop, odor of alcohol, performance on the field sobriety tests, and appellant’s admission that he had been drinking all support the officer’s probable cause to detain and arrest. See
State v. Williams
(1992),
Courts have rejected arguments similar to appellant’s in other cases. In
State v. Chelikowsky
(Aug. 18, 1992), Pickaway App. No. 91CA27, unreported,
The trial court’s factual findings, based upon the officer’s testimony, are supported by competent, credible evidence. We have independently determined that those faсts establish the officer’s probable cause to arrest and consequently to administer the breath-alcohol test. Accordingly, trial court did not err by denying appellant’s motion to suppress. For all of the foregoing reasons, we overrule appellаnt’s assignment of error and affirm the judgment of the trial court.
Judgment affirmed.
