Wilmoth v. Director of Revenue
Annotate this Case
The Supreme Court affirmed the judgment of the circuit court affirming the decision of the director of revenue to suspend Defendant's driver's license pursuant to Mo. Stat. 302.505, holding that the circuit court did not err in admitting testimony that a preliminary breath test was greater than 0.08 percent or in finding that Defendant was arrested upon probable cause for an alcohol-related offense.
Specifically, the Supreme Court held (1) the result of a preliminary breath test is a numerical percentage by weight of alcohol in the blood of the test person, and section 577.021.3 allows a court to admit the result as evidence of probable cause to arrest; (2) because the numerical result in this case was known to the arresting officer at the time of arrest the circuit court was allowed to consider it in determining that the officer had probable cause to arrest Defendant; and (3) the judgment was supported by substantial evidence and was not against the weight of the evidence.
