Scott Raisher appeals the trial court judgment affirming the Director of Revenue’s suspension of his driver’s license. Mr. Raisher claims the trial court erred in its decision because it allowed an officer’s testimony to invalidate scientific data. We reverse.
Factual and Procedural Background
Mr. Raisher was driving home when State Trooper Steven Salfrank pulled him over for failing to maintain his lane. Trooper Salfrank smelled alcohol in Mr. Raisher’s truck and noticed that his eyes were bloodshot and watery. Trooper Sal-frank asked Mr. Raisher if he had been drinking. Mr. Raisher responded, “Not too much.” Mr. Raisher performed three sobriety field tests; his performance indicated that he was intoxicated. During the administering of these tests, Trooper Sal-frank heard Mr. Raisher speak in a mumbled and slurred voice. He arrested Mr. Raisher for driving while intoxicated. At the police station, Trooper Salfrank read an “Implied Consent Law” form, advising Mr. Raisher that he could submit to a breathalyzer test or refuse and have his license revoked. Mr. Raisher consented to the test.
After Trooper Salfrank, a Type II permit holder, instructed Mr. Raisher, Mr. Raisher blew into the breathalyzer also called the DataMaster. Noticing that Mr. Raisher was not breathing according to his instructions, Trooper Salfrank told Mr. Raisher to move away from the machine. The machine printed out a report indicat *364 ing Mr. Raisher’s blood alcohol content (BAC) was .078%, under the legal limit of intoxication. Trooper Salfrank reinstruct-ed Mr. Raisher on how to breathe and ordered Mr. Raisher to breathe again using this technique. He warned Mr. Raisher that failure to comply would amount to a refusal. Mr. Raisher complied and the machine printed out a report indicating Mr. Raisher’s BAC was .094%, over the legal limit of intoxication.
The Director suspended Mr. Raisher’s license under section 302.505 1 based on the second BAC reading of .094%. Mr. Raisher filed a petition for review in the circuit court. He argued that his BAC was below the legal limit as evidenced by the first BAC reading of .078%. The Director adduced evidence that the difference between the two test results was attributable to Mr. Raisher’s improper breathing. Mr. Raisher adduced evidence that the machine contained software to detect improper breath samples by providing an error code and that no error code displayed on the machine during the first test. After hearing the evidence, the circuit court affirmed the Director’s suspension of Mr. Raisher’s license; it did not explain its decision. Mr. Raisher appeals.
Standard of Review
We affirm the trial court’s judgment affirming the suspension of a driver’s license unless the decision is against the weight of the evidence, there is no substantial evidence to support the decision, or the decision erroneously applies or declares the law.
Kisker v. Dir. of Revenue,
Legal Analysis
In his sole point, Mr. Raisher argues that the trial court erroneously applied the law when it affirmed the Director’s decision to suspend his license because in doing so, it shifted the Director’s burden of persuasion to him. The Director has the burden of proof to establish by a preponderance of evidence that probable cause existed to arrest the driver for driving while intoxicated and that an evi-dentiary breath test determined the driver’s BAC was beyond the legal limit.

Verdoorn v. Dir. of Revenue,
It is undisputed that the Director established a
prima facie
case against Mr. Ra-isher for driving while intoxicated. There was probable cause to arrest Mr. Raisher, and a breathalyzer test result showed that his BAC level was beyond the legal limit. Moreover, there was a
prima facie
foundation to admit both BAC test results.
See Green v. Dir. of Revenue,
*365
Mr. Raisher contends that he rebutted the Director’s
prima facie
case by introducing the first BAC reading of .078%. Rebuttal evidence must raise a genuine issue of fact “as to whether [the driver’s] blood alcohol concentration was above the legal limit at the time” he was arrested.
See Kisker,
Mr. Raisher adduced evidence that the breathalyzer reported a legal BAC level of .078%, the first time he blew into the machine. Two conflicting BAC results computed within minutes of each other, on the same machine by the same operator, raises a genuine issue as to whether Mr. Raisher’s BAC was above the legal limit. Thus, Mr. Raisher rebutted the prima fa-cie case by providing scientific evidence that his BAC was below the legal limit. The question becomes whether the Director showed by a preponderance of the evidence, in light of Mr. Raisher’s rebuttal evidence, that Mr. Raisher’s BAC level was above the legal limit.
Preponderance of the evidence is “that degree of evidence that is of greater weight or more convincing than the evidence which is offered in opposition to it; that is, evidence which as a whole shows the fact to be proved to be more probable than not.”
Bain v. Wilson,
We are cognizant that we have deferred to the trial court’s ruling where evidence could support two different conclusions.
Baldridge v. Dir. of Revenue,
Here, the issue is not refusal but whether the Director proved by a preponderance of the evidence that Mr. Raisher’s BAC level was above the legal limit. Had Mr. Raisher’s denial of the improper breathing been the only evidence in conflict with the trooper’s testimony, we would agree with the Director that the issue is one of credibility, as decided in Baldridge. But Mr. Raisher also adduced testimony from the same trooper that the DataMaster is equipped with software to ensure that the breath sample meets its parameters, that the machine would generate an error code if the breath sample failed to meet those minimum parameters, and that the machine did not generate such a message but instead analyzed the breath sample. Thus, the issue is not credibility, but whether the evidence that Mr. Raisher did not breathe properly during the first test has greater weight than the machine’s complete analysis of that same breath sample in determining whether it is more probable than not that the second test is more accurate than the first test. In other words, we must decide whether the trooper’s observation is sufficient to overcome the presumed validity of the first test result.
Mr. Raisher argues that our precedent “ha[s] taught that a trial court may not disregard, ignore, or refuse to admit a chemical test result obtained in compliance with the regulations of the department of health and senior services.” In
Fitzgerald v. Director of Revenue,
this court held that the trial court erroneously applied the law when it found a breath test result was unreliable absent evidence that the machine malfunctioned.
Here, the Director did not adduce any scientific evidence to invalidate the BAC reading of .078% from the breathalyzer but attributed this test result to improper breathing. Precedent suggests that when an officer observes a driver improperly
*367
breathing, the machine verifies improper breathing by failing to analyze the breath sample or by failing to print out a test result.
See Snow v. Dir. of Revenue,
The doctrine of destructive contradictions provides that testimony loses its probative value when it “is so inherently incredible, self destructive or opposed to known physical facts on a vital point or element that reliance on the testimony is necessarily precluded”.
State v. Davison,
Conclusion
Therefore, we conclude that Mr. Raisher successfully rebutted the Director’s prima facie case with his first BAC reading of .078%, because the trooper’s testimony was insufficient to invalidate that test result. Neither test result shows insufficient sample nor any other error, so neither test is proof of Mr. Raisher’s BAC level. The burden is on the Director to prove by a preponderance of evidence that the driver’s blood alcohol content exceeded the legal limit. At best, the evidence of Mr. Raisher’s BAC level is in equipoise and, therefore, the Director has not met its burden of proof. When faced with mutually exclusive test results from the same machine, it is incumbent upon the Director to produce additional evidence that the driver’s BAC exceeded the legal limit by an additional test result either from a different type of test (blood or saliva) or perhaps from a different breathalyzer. Without scientific proof that the second test result is more accurate than the first test result, the trial court erred in finding the Director carried his burden.
Our decision does not cause a hardship to the Director because if an officer is dissatisfied with the results of the breath

test, under section 577.020

the driver must submit to a second type of chemical test: either a blood, urine, or a saliva test.
