SUPREME COURT OF MISSOURI en banc DAVID PRIOR WILMOTH, ) Opinion issued June 13, 2023 ) Appellant, ) ) v. ) No. SC99655 ) DIRECTOR OF REVENUE, ) ) Respondent. )
APPEAL FROM THE CIRCUIT COURT OF CLINTON COUNTY The Honorable Teresa L. Bingham, Judge
David Wilmoth appeals a judgment affirming the director of revenue’s suspension of
his driver’s license, pursuant to section 302.505, 1 because the circuit court found
Mr. Wilmoth was arrested upon probable cause to believe he committed an alcohol-related
traffic offense and he was driving with a blood alcohol content of eight-hundredths of one
percent or more. Mr. Wilmoth claims the circuit court erred in admitting testimony that a
preliminary breath test administered prior to arrest showed his breath alcohol content was
greater than 0.08 percent in violation of section 577.021.3. 2 He claims the circuit court
further erred because its finding he was arrested upon probable cause for an alcohol-related

evidence.
The Court finds the result of a preliminary breath test is a numerical percentage by
weight of alcohol in the blood of the person tested, which section 577.021.3 provides is
admissible as evidence of probable cause to arrest. The numerical result was one of the facts
and circumstances known to the arresting officer at the time of arrest, so the circuit court is
to consider the numerical result in determining whether the officer had probable cause to
arrest Mr. Wilmoth. Accordingly, the circuit court did not err in permitting the arresting
officer to testify the result of the preliminary breath test administered to Mr. Wilmoth was a
blood alcohol content greater than 0.08 percent. The Court also finds the circuit court’s
judgment is supported by substantial evidence and is not against the weight of the evidence.
The circuit court’s judgment is, therefore, affirmed.
Factual and Procedural Background
In November 2019, Deputy Cole Mazer of the Clinton County sheriff’s office
responded to a report of a domestic assault at the Wilmoth residence, allegedly involving a
firearm. On his way to the residence, Deputy Mazer was informed Mr. Wilmoth had left the
residence in a utility terrain vehicle (“UTV”). Deputy Mazer was given a description of
Mr. Wilmoth and the UTV he was driving. He later observed the UTV on a public gravel
road and caught up to him “in a cloud of dust” the UTV “kicked up from the gravel
roadway.” When Deputy Mazer observed Mr. Wilmoth make a left turn without signaling,
he initiated a traffic stop.
2 During the traffic stop, Deputy Mazer detected a moderate odor of alcohol on
Mr. Wilmoth’s breath and observed his eyes were bloodshot and watery. Mr. Wilmoth
admitted to consuming a couple of beers with dinner “around” three and a half hours earlier.
The deputy’s observations prompted him to request that Mr. Wilmoth take a preliminary
breath test. Mr. Wilmoth complied, and the test result was 0.11 percent. Mr. Wilmoth
refused to perform other field sobriety tests.
Deputy Mazer then arrested Mr. Wilmoth for driving while intoxicated and
transported him to the county jail. After observing Mr. Wilmoth for a 15-minute period,
Deputy Mazer administered two breath tests. The result of the first test was a blood alcohol
content of 0.082 percent, and the second, administered approximately five minutes later, was
0.086 percent.
Pursuant to section 302.505, the director of revenue notified Mr. Wilmoth his driving
privilege would be suspended for being arrested upon probable cause to believe he was
operating a motor vehicle with a blood alcohol content in excess of 0.08 percent. After the
administrative hearing Mr. Wilmoth requested, the administrative hearing officer sustained
the director’s suspension of Mr. Wilmoth’s driver’s license. Mr. Wilmoth then requested a
trial de novo in the circuit court.
During a bench trial, the circuit court allowed Deputy Mazer to testify, over
Mr. Wilmoth’s objection, that the preliminary breath test showed Mr. Wilmoth’s blood
alcohol content was greater than 0.08 percent. The colloquy regarding Deputy Mazer’s
testimony as to the preliminary breath test was:
MR. BAKER [counsel for the department of revenue]: Do you recall the result of the preliminary breath test? 3 MR. SHIPLEY [counsel for Mr. Wilmoth]: Your Honor, I’m going to object if he’s intending to testify to any specific numerical result. Under section 577.021, a preliminary breath test may be admissible if it’s positive as to probable cause but not admissible as to the evidence of blood alcohol content.
MR. BAKER: Well, that’s exactly why I’m asking, Your Honor, to establish probable cause. This is prearrest and I’m not trying to elicit the result necessarily for the evidential breath test post-arrest. This is to establish that the officer did have probable cause to arrest, and I believe the case of State v. Roux, R-o-u-x,[ 3] states in part that the result, the actual result of the preliminary breath test, is relevant in establishing probable cause.
THE COURT: Relevant in that if it was under a certain number then he wouldn’t have probable cause.
MR. BAKER: Essentially, yes.
MR. SHIPLEY: Your Honor, I’m objecting on the – the statute specifically says that the evidence of blood alcohol content is not admissible. And beyond that, I think he could just testify if he says it was positive because I think that, you know, positive or negative, that the statute allows for that but just to the alcohol content it doesn’t. And moreover, as to this particular case and I think it distinguishes it from the Roux case is you’re basically talking about a scientific test for which there is no foundation or evidence to how the test works, how it’s qualified, that it’s a legitimate test. So I object on that basis as well.
THE COURT: . . . [T]he court is going to sustain his objection as to the actual number being used. You can ask questions with regards to the remainder of that.
MR. BAKER: Thank you.
MR. BAKER: Was the result positive or negative for the purpose [sic] of alcohol when Mr. Wilmoth submitted to a preliminary breath test?
DEPUTY MAZER: Positive.
MR. BAKER: Was it above or below .08?
3 State v. Roux, 554 S.W.3d 416 (Mo. App. 2017). 4 MR. SHIPLEY: Object, Your Honor, as to – that’s getting to the exact number of the test, which I think it the same thing you sustained the objection as to.
MR. BAKER: Your Honor, State v. Roux applies directly to this. The Southern District stated that a result above .08 is – is essential – not essential – is evidence of probable cause. A result below .08 would not necessarily lead to probable cause.
MR. SHIPLEY: Your Honor, also, that case did not deal, again, with the foundation objection I’ve made that whether it could ultimately be relevant or not there’s no foundation for the reliability of that test or that it’s scientifically accurate.
MR. BAKER: There’s numerous case law [sic] that says foundation for a preliminary breath test is not required in a license suspension case.
MR. SHIPLEY: Well, Your Honor, I think foundation, again, is to – whether it’s positive or negative, I think that’s true and that’s what the statute says, but I’m talking about the foundation as to a specific number, the reliability of the test to give a value.
THE COURT: The Court is going to overrule the objection. Go ahead, Mr. Baker.
MR. BAKER: Thank you, Judge.
DEPUTY MAZER: It was above.
The circuit court also admitted into evidence the alcohol influence report prepared by
Deputy Mazer that included information regarding his administration of the preliminary
breath test to Mr. Wilmoth. That report listed the numerical result of the preliminary breath
test as 0.11 percent. In response to Mr. Wilmoth’s objection to the numerical result in the
exhibit, the circuit court admitted the report but stated it would “disregard the actual numeric
number of [the preliminary breath test] and take instead the officer’s testimony that it was
above .08 [percent].” In its written findings of fact and conclusions of law, the circuit court
5 found the director’s evidence credible; there was probable cause to arrest Mr. Wilmoth for
an alcohol-related offense; and Mr. Wilmoth was driving with a blood alcohol content of
0.08 percent or more. Consequently, the circuit court sustained the suspension of
Mr. Wilmoth’s license. Mr. Wilmoth appealed, and this Court granted transfer after an
opinion by the court of appeals. Mo. Const. art. V, sec. 10.
Standard of Review
In an appeal from a judgment in a court-tried case, the circuit court’s judgment will
be affirmed unless there is no substantial evidence to support it, it is against the weight of
the evidence, or it erroneously declares or applies the law. Murphy v. Carron, 536 S.W.2d
30, 32 (Mo. banc 1976). With respect to the admission of evidence, review is for an abuse
of discretion. Vanderpool v. Dir. of Revenue, 226 S.W.3d 108, 109 (Mo. banc 2007). A
circuit court abuses its “discretion when its ruling is clearly against the logic of the
circumstances then before the court and is so unreasonable and arbitrary that it shocks the
sense of justice and indicates a lack of careful, deliberate consideration.” Lozano v. BNSF
Ry. Co., 421 S.W.3d 448, 451 (Mo. banc 2014) (internal quotation omitted). Finally,
questions of statutory interpretation are issues of law this Court reviews de novo. Stiers v.
Dir. of Revenue, 477 S.W.3d 611, 614 (Mo. banc 2016).
No Error in Admitting Preliminary Breath Test Result
Mr. Wilmoth claims the circuit court erred in allowing Deputy Mazer to testify the
result of the preliminary breath test was greater than 0.08 percent because he contends
section 577.021 provides the result of a preliminary breath test is inadmissible as evidence
6 of blood alcohol content and the deputy’s testimony about the preliminary breath test lacked
an adequate foundation.
Mr. Wilmoth challenges the suspension of his driver’s license pursuant to section
302.505. The statute requires the department of revenue to suspend or revoke the driver’s
license of a person 21 years of age or older “upon its determination that the person was
arrested upon probable cause to believe such person was driving a motor vehicle while the
alcohol concentration in the person’s blood, breath, or urine was eight-hundredths of one
percent or more by weight . . . .” Section 302.505.1. At a trial de novo, the director must
present “evidence that: (1) the driver was arrested upon probable cause for violating an
alcohol-related offense; and (2) the driver’s blood alcohol concentration exceeded the legal
limit . . . .” Verdoorn v. Dir. of Revenue, 119 S.W.3d 543, 545 (Mo. banc 2003), overruled
in part on other grounds by White v. Dir. of Revenue, 321 S.W.3d 298, 307 (Mo. banc 2010).
The director bears the burdens of proof and persuasion. White, 321 S.W.3d at 305.
As evidence regarding whether Mr. Wilmoth was arrested upon probable cause for
violating an alcohol-related offense, the director elicited Deputy Mazer’s testimony that he
administered a preliminary breath test and that test showed a blood alcohol concentration
greater than 0.08 percent. The pre-arrest administration of a preliminary breath test is
authorized by section 577.021.1, which provides certain law enforcement officers “may,
prior to arrest, administer a chemical test to any person suspected of operating a
vehicle . . . while in an intoxicated condition or with an excessive blood alcohol content.”
Subsection 3 of section 577.021 permits the admission of the results of a preliminary breath
7 test administered under section 577.021 as evidence of probable cause to arrest and as
exculpatory evidence but precludes its admission as evidence of blood alcohol content.
In his argument, Mr. Wilmoth concedes the result of the preliminary breath test was
admissible for the purpose of establishing whether he was arrested upon probable cause for
violating an alcohol-related offense, but he argues Deputy Mazer’s testimony should have
been limited to stating whether the preliminary breath test was positive for the presence of
alcohol. He argues the holdings of the court of appeals in State v. Eisenhour, 410 S.W.3d
771, 776 (Mo. App. 2013), and State v. Duncan, 27 S.W.3d 486 (Mo. App. 2000), support
his claim that permitting the deputy to testify as to the numerical result of the test or that the
result was greater than 0.08 percent would be to use the preliminary breath test as evidence
of blood alcohol content, in violation of section 577.021.3’s prohibition against its use for
that purpose. See Eisenhour, 410 S.W.3d at 778 (holding the “numerical value” of a positive
preliminary breath test is inadmissible as exculpatory evidence because section 577.021.3
provides the test “shall not be admissible as evidence of blood alcohol content”); Duncan,
27 S.W.3d at 488 n.1 (holding testimony about a preliminary breath test is inadmissible “in
its entirety” as evidence to prove a defendant’s blood alcohol level exceeded the legal limit).
The holding in Duncan can easily be distinguished from the facts of this case because the
court of appeals ruled evidence of the result of the preliminary blood test was not admissible
in a criminal trial as evidence of the defendant’s intoxication. Duncan, 27 S.W.3d at 488
n.1. The court of appeals held in Eisenhour that the numerical result of a preliminary breath
test is not admissible as evidence of blood content in a criminal trial, even when offered as
exculpatory evidence. Eisenhour, 410 S.W.3d at 778.
8 Although the Eisenhour and Duncan decisions do not support Mr. Wilmoth’s claim
of error, the Court notes the court of appeals’ decisions regarding the admission in evidence
of the results of a preliminary breath test are inconsistent. The court of appeals has limited
admission of the result of a preliminary breath test to evidence of whether a breath test is
positive or negative for the presence of alcohol. See, e.g., State v. Long, 599 S.W.3d 908,
919 (Mo. App. 2020) (“Defendant also was correctly informed that the [preliminary breath
test] is used only to determine whether a breath test is positive or negative for alcohol.”). In
contrast, in Roux, the court of appeals held it was an abuse of discretion not to admit the
“actual, numerical result” of a preliminary breath test for the purpose of establishing
probable cause because “the actual numerical value of the test is what makes the result of
the portable breath test relevant to the issue of probable cause.” Roux, 554 S.W.3d at 418-
19. It is a matter of first impression for this Court as to whether the numerical result of a
preliminary breath test is admissible for the purpose of establishing probable cause, which
must be proven for the director of revenue to suspend or revoke a driver’s license pursuant
to section 302.515.
Determining the meaning of section 577.021 begins with examining the language of
the statute. “When interpreting statutes, this Court must ascertain the intent of the legislature
by considering the plain and ordinary meaning of the terms and give effect to that intent if
possible.” Cosby v. Treasurer of Mo., 579 S.W.3d 202, 206 (Mo. banc 2019) (alteration
omitted). As previously noted, section 577.021.1 authorizes certain law enforcement
officers to administer a chemical test prior to arrest when the officer suspects the person of
operating a vehicle “while in an intoxicated condition or with excessive blood alcohol
9 content.” Section 577.021.1. Pursuant to this section, law enforcement officers administer
preliminary breath tests to “detect the presence of alcohol on a person’s breath” and
determine whether there exists probable cause to arrest. State v. Stottlemyre, 35 S.W.3d 854,
858 (Mo. App. 2001). Subsection 2 of section 577.021 requires the same law enforcement
officers to “make all reasonable efforts to administer a chemical test to any person suspected
of operating a vehicle or vessel involved in a collision or accident which resulted in a fatality
or serious physical injury . . . .” Subsection 3 of section 577.021 provides a preliminary
breath test administered pursuant to subsection 1 of the statute is admissible for the purpose
of establishing “probable cause to arrest and as exculpatory evidence” but inadmissible “as
evidence of blood alcohol content.” Section 577.021.3 provides:
A test administered pursuant to this section shall be admissible as evidence of probable cause to arrest and as exculpatory evidence, but shall not be admissible as evidence of blood alcohol content. The provisions of sections 577.019 and 577.020 shall not apply to a test administered prior to arrest pursuant to this section.
(Emphasis added).
Section 577.021.3 plainly states “[a] test administered pursuant to this section shall
be admissible as evidence of probable cause to arrest[.]” Section 577.021.3. “Probable
cause to arrest exists when the arresting officer’s knowledge of the particular facts and
circumstances is sufficient to warrant a prudent person’s belief that a suspect has committed
an offense.” White, 321 S.W.3d at 312 (emphasis added). Whether probable cause to arrest
exists includes consideration of the conclusions “an objectively reasonable police officer”
would draw from the facts and circumstances known to the officer. Ornelas v. United States,
517 U.S. 690, 696 (1996). As such, probable cause is an objective test. Id. To make an
10 accurate determination of whether an officer had probable cause, courts must consider all
the facts and circumstances known to the officer at the time of arrest. Devenpeck v. Alford,
543 U.S. 146, 152 (2004).
When an officer administers a preliminary breath test under section 577.021.1, the
test produces a numerical quantification of the alcohol content of a person’s blood, in this
case 0.11 percent. Accordingly, when making a probable cause determination, an officer
knows the numerical result of the preliminary breath test. The higher the numerical result
is, the more reasonable the officer’s belief that the suspect has committed an alcohol-related
offense. “A reasonable officer, when faced with a [preliminary] breath test result of [0].08
percent or more would be justified in believing the driver was impaired so as to support a
finding of probable cause.” See Roux, 554 S.W.3d at 418. Because courts assessing whether
an officer has probable cause to arrest for an alcohol-related offense must consider the
information known to the officer at the time of arrest and, in this case, Deputy Mazer knew
the preliminary breath test showed a blood alcohol content of 0.11 percent, that result is
admissible evidence of whether the deputy had probable cause to arrest Mr. Wilmoth.
The fact a preliminary breath test cannot be admitted as evidence to prove a
defendant’s blood alcohol content did not require the circuit court to exclude Deputy
Mazer’s testimony. In providing a preliminary breath test is admissible for some purposes
but not another, section 577.021.3 permits limited admissibility of a preliminary breath test.
It is common that evidence may be admitted for one purpose and not others, and courts have
consistently held that, in such circumstances, the evidence should be admitted for its proper
purpose. Grimm v. Gargis, 303 S.W.2d 43, 51 (Mo. 1957); Louis Steinbaum Real Estate
11 Co. v. Maltz, 247 S.W.2d 652, 656 (Mo. 1952); Scott v. Mo. Ins. Co., 233 S.W.2d 660, 665
(Mo. banc 1950); Heckadon v. Universal Underwriters Ins. Co., 586 S.W.3d 789, 811
(Mo. App. 2019); Danbury v. Jackson Cnty., 990 S.W.2d 160, 165 (Mo. App. 1999). In this
case, the test results were offered to prove Deputy Mazer had probable cause to arrest, not
Mr. Wilmoth’s blood alcohol content. While the director must prove both that the officer
had probable cause to arrest and that the driver’s blood alcohol content was 0.08 percent or
more, the latter must be proved by evidence other than the results of the preliminary breath
test, as it was here. Put another way, the information known to Deputy Mazer was not that
Mr. Wilmoth’s blood alcohol content actually was 0.11 percent. It was merely that the
preliminary breath test returned a result of 0.11 percent, subject to all the potential
unreliability of that test.
When evidence of limited admissibility is admitted in a court-tried case, it is
presumed the circuit court will consider it only for proper purposes “unless it is clear from
the record that the judge considered and relied upon such evidence” for an improper purpose.
State v. Burks, 373 S.W.3d 1, 8 (Mo. App. 2012). Indeed, “[t]rial judges are perfectly
capable of receiving some evidence for one purpose and not another.” J.A.R. v. V.A.R., 968
S.W.2d 748, 751 (Mo. App. 1998). Therefore, circuit courts may admit the numerical results
of a preliminary breath test, including testimony that the preliminary breath test was greater
than 0.08 percent, for the purpose of establishing probable cause to arrest pursuant to section
577.021.3.
Mr. Wilmoth also claims that the circuit court should have excluded Deputy Mazer’s
testimony that the preliminary breath test was greater than 0.08 percent because there was
12 an inadequate foundation for admission of the testimony. At trial, the director did not present
testimony to establish a foundation for the preliminary breath test’s reliability as to a specific
result, or a result above a certain level, and, on cross-examination of Deputy Mazer,
Mr. Wilmoth elicited testimony the deputy did not know how the test worked and could not
vouch for any specific results. Mr. Wilmoth claims section 490.065.1(1), RSMo Supp. 2017,
requires that a person attempting to testify regarding scientific or technical knowledge be
qualified by knowledge, skill, experience, training, or education prior to testifying, so
testimony regarding the preliminary breath test should have been excluded due to lack of
foundation.
Section 577.021.1 requires only that the law enforcement officer be certified
“pursuant to chapter 590” and it expressly provides the requirements in sections 577.019
and 577.020 “shall not apply to a test administered prior to arrest pursuant to [section
577.021].” Section 577.019 merely provides sections 577.019 to 577.021 “shall be known
as the Alan Woods Law,” but section 577.020 is more significant. Section 577.020 governs
breath analysis tests that are administered after a suspect has been arrested pursuant to
implied consent and used to prove a person was intoxicated. Section 577.020.4 directs the
department of health and senior services to establish methods and standards “to be used in
the chemical test pursuant to the provisions of sections 577.019 to 577.041.” By exempting
preliminary breath tests from the provisions of section 577.020, section 577.021.3 exempts
preliminary breath tests from “the Department of Health regulations that govern breath
analysis tests admissible to prove that a defendant was intoxicated” and reflects a legislative
determination a preliminary breath test lacks the guarantees of reliability of other chemical
13 tests subject to the provisions of section 577.020. State v. Morgenroth, 227 S.W.3d 517,
522 (Mo. App. 2007) (internal quotations omitted). But section 577.021.3 expressly permits
preliminary breath test results to be used as evidence of probable cause even though they are
not subject to the provisions of sections 577.019 and 577.020. The lack of evidence
regarding the foundational requirements for tests used to prove blood alcohol content is not
a basis for excluding the results of the preliminary breath test used as evidence of probable
cause.
At trial, the director elicited Deputy Mazer’s testimony about the preliminary breath
test and it was admitted expressly for the purpose of establishing probable cause. When
Mr. Wilmoth objected to the director’s attempt to elicit that testimony, counsel for the
director stated: “This is prearrest and I’m not trying to elicit the result necessarily for the
evidential breath test post-arrest. This is to establish that the officer did have probable cause
to arrest[.]” (Emphasis added). Because section 577.021.3 provides a preliminary breath
test is admissible as evidence of probable cause and the existence of probable cause depends
upon the information known to the arresting officer at the time of arrest, the circuit court did
not err in allowing Deputy Mazer to testify the preliminary breath test result was greater than
0.08 for the purpose of establishing probable cause.
Probable Cause Supported by Substantial Evidence
Mr. Wilmoth next claims the circuit court’s finding that he was arrested upon
probable cause for violating an alcohol-related offense is not supported by sufficient
evidence. He claims the evidence supports a finding there was probable cause to believe he
14 consumed alcohol, but the evidence does not support finding probable cause to believe he
was actually intoxicated.
“Substantial evidence is evidence that, if believed, has some probative force on each
fact that is necessary to sustain the circuit court’s judgment.” Ivie v. Smith, 439 S.W.3d 189,
199 (Mo. banc 2014). “When reviewing whether a circuit court’s judgment is supported by
substantial evidence, appellate courts view the evidence in the light most favorable to the
circuit court’s judgment and defer to the circuit court’s credibility determinations.” Id. at
200. The Court disregards all contrary evidence and accepts as true the evidence and
inferences favorable to the circuit court’s judgment. Id. “To prevail on the
substantial-evidence challenge, [Mr. Wilmoth] must demonstrate that there is no evidence
in the record tending to prove a fact that is necessary to sustain the circuit court’s judgment
as a matter of law.” Id.
The director is authorized to suspend a driver’s license when the arresting officer had
probable cause to believe the person was driving a vehicle with a blood alcohol content of
0.08 percent or more. Section 302.505.1. When determining whether an officer had such
probable cause, the Court applies the following analysis:
The probable cause required for the suspension or revocation of a driver’s license is the level of probable cause necessary to arrest a driver for an alcohol-related violation. That level of probable cause will exist when a police officer observes unusual or illegal operation of a motor vehicle and observes indicia of intoxication upon coming into contact with the motorist. Probable cause, for the purposes of section 302.505, will exist when the surrounding facts and circumstances demonstrate to the senses of a reasonably prudent person that a particular offense has been or is being committed. The level of proof necessary to show probable cause under section 302.505 is substantially less than that required to establish guilt beyond a reasonable doubt. There is a vast gulf between the quantum of information necessary to establish probable cause and the quantum of evidence required to prove guilt beyond a reasonable 15 doubt. The trial court must assess the facts by viewing the situation as it would have appeared to a prudent, cautious, and trained police officer.
White, 321 S.W.3d at 309 (internal quotations omitted). Furthermore, when reviewing a
circuit court’s probable cause determination in a license suspension or revocation case, this
Court defers to the circuit court’s credibility determinations but reviews de novo the circuit
court’s application of the law to the facts. Id. at 310.
In its judgment, the circuit court expressly found the director’s evidence was credible.
That evidence included Deputy Mazer’s testimony he observed Mr. Wilmoth make a
left-hand turn without signaling, Mr. Wilmoth had bloodshot and watery eyes, and he
detected the odor of an “intoxicating beverage” on Mr. Wilmoth’s breath. He also testified
Mr. Wilmoth admitted he had been drinking earlier that night and the result of the
preliminary breath test was 0.11 percent. 4
Mr. Wilmoth’s argument there is insufficient evidence does not properly consider the
evidence of the preliminary breath test result, as he concludes it could only be considered
insofar as it was positive for the presence of alcohol. In his view, the circuit court could not
have considered that the preliminary breath test was greater than 0.08 percent, much less
that it was 0.11 percent. As this Court explained in discussing Mr. Wilmoth’s first point,
however, section 577.021.3 makes a preliminary breath test admissible to establish probable
cause, and probable cause is determined from the information known the officer at the time
of arrest. Accordingly, the preliminary breath test result of 0.11 must be considered along
4 The Court stresses the information known to Deputy Mazer was not that Mr. Wilmoth’s blood alcohol content was 0.11 percent but rather that the preliminary breath test returned a result of 0.11 percent. 16 with evidence Mr. Wilmoth made a left-hand turn without signaling, Mr. Wilmoth had
bloodshot and watery eyes, the odor of an “intoxicating beverage” was detected on
Mr. Wilmoth’s breath, and Mr. Wilmoth admitted that he had been drinking earlier that night
when determining whether the officer had probable cause. Considered cumulatively, the
information Deputy Mazer possessed would have justified “a prudent, cautious, and trained
police officer” in believing Mr. Wilmoth had been driving while intoxicated. See id. at 309.
Therefore, the circuit court’s finding of probable cause is supported by substantial evidence. 5
Probable Cause Not Against Weight of Evidence
In his final point, Mr. Wilmoth argues the circuit court’s finding of probable cause
was against the weight of the evidence. “Appellate courts act with caution in exercising the
power to set aside a decree or judgment on the ground that it is against the weight of the
evidence.” Ivie, 439 S.W.3d at 205. “The against-the-weight-of-the-evidence standard
serves only as a check on a circuit court’s potential abuse of power in weighing the evidence,
and an appellate court will reverse only in rare cases, when it has a firm belief that the decree
or judgment is wrong.” Id. at 206. A “judgment is against the weight of the evidence only
5 In its opinion issued prior to transfer, the court of appeals relied in part on Mr. Wilmoth’s refusal to submit to any field sobriety testing after Deputy Mazer administered the preliminary breath test. On appeal in this Court, Mr. Wilmoth challenges whether that refusal can be considered as evidence of probable cause to arrest for driving while intoxicated. It is unnecessary to resolve whether his refusal can be considered because the circuit court’s judgment is supported by substantial evidence without it. Likewise, he challenges any consideration of the fact Deputy Mazer was dispatched in response to a report of a domestic disturbance, which the deputy testified, in his experience, heightened the probability the suspect had consumed intoxicating substances. As with his refusal to submit to field sobriety testing, the Court does not address whether the deputy responding to a report of domestic violence can be considered for purposes of probable cause. The circuit court’s finding of probable cause is supported by substantial evidence without it. 17 if the circuit court could not have reasonably found, from the record at trial, the existence of
a fact that is necessary to sustain the judgment.” Laut v. City of Arnold, 491 S.W.3d 191,
197 (Mo. banc 2016) (internal quotation omitted).
“The level of proof necessary to show probable cause under section 302.505 is
substantially less than that required to establish guilt beyond a reasonable doubt.” White,
321 S.W.3d at 309 (internal quotation omitted). And the necessary “level of probable cause
will exist when a police officer observes unusual or illegal operation of a motor vehicle and
observes indicia of intoxication on coming into contact with the motorist.” Id. (internal
quotation omitted).
As discussed in the previous point, the circuit court’s probable cause finding is
supported by substantial evidence. The circuit court expressly found the director’s evidence
credible, and that evidence included Deputy Mazer’s testimony that he observed
Mr. Wilmoth make a left-hand turn without signaling, the deputy’s testimony that
Mr. Wilmoth had bloodshot and watery eyes, the deputy’s testimony that he detected the
odor of an “intoxicating beverage” on Mr. Wilmoth’s breath, Mr. Wilmoth’s admission that
he had been drinking earlier that night, and a preliminary breath test result of 0.11 percent.
Mr. Wilmoth claims other evidence contradicts the conclusion that the deputy had
probable cause to arrest for an alcohol-related offense. During Mr. Wilmoth’s
cross-examination, the deputy conceded the smell of alcohol does not necessarily show
impairment and he was unable to quantify the number of drinks Mr. Wilmoth had based on
the smell alone; the deputy agreed bloodshot and watery eyes could have been from driving
18 a UTV down a gravel road; bloodshot eyes do not necessarily result from impairment; and
the deputy observed no “physical signs” of impairment.
Further, Mr. Wilmoth relies on the deputy’s testimony that he saw no signs of
impairment in Mr. Wilmoth’s driving as he pulled over immediately. The deputy did not
observe “glassy” eyes, staring eyes, constricted pupils, slow reaction to light, dilated pupils,
uncertain balance, swaying staggering, stumbling, falling, any other factors indicating
problems with balance or walking, slurred speech, confused speech, incoherent speech,
stuttering, mumbling, any other problems with speech, profanity, hiccups, belching,
vomiting, fighting, or any other unusual actions that might indicate impairment, and Deputy
Mazer did not notice anything about Mr. Wilmoth’s clothes or footwear that indicated
impairment. While such facts can be relevant in assessing whether a person is intoxicated,
the absence of those facts does not equate to a person not being intoxicated.
Given the substantially lesser level of proof needed to show probable cause than to
establish guilt beyond a reasonable doubt, White, 321 S.W.3d at 309, the Court is not
persuaded the circuit court’s judgment is against the weight of the evidence. To restate the
standard of review, a “judgment is against the weight of the evidence only if the circuit court
could not have reasonably found, from the record at trial, the existence of a fact that is
necessary to sustain the judgment.” Laut, 491 S.W.3d at 197 (internal quotation omitted).
Notwithstanding Deputy Mazer’s testimony that he did not observe many possible indicia
of intoxication, the circuit court could have reasonably found from the record at trial –
including the fact he made a turn without signaling, that Deputy Mazer detected the odor of
alcohol on his breath, his admission that he consumed alcohol earlier that night, and that the
19 result of the preliminary breath test was a blood alcohol content of 0.11 percent – that there
was probable cause to arrest Mr. Wilmoth for driving while intoxicated. The circuit court’s
judgment is not against the weight of the evidence, and Mr. Wilmoth’s third point is denied.
Conclusion
The circuit court did not err in allowing the arresting deputy to testify the result of
the preliminary breath test administered prior to Mr. Wilmoth’s arrest was a blood alcohol
content greater than 0.08 percent. The testimony was elicited solely for the purpose of
establishing probable cause, pursuant to section 577.021.3, and whether probable cause
exists depends on the information known to the officer at the time of arrest, which includes
the numerical result of the preliminary breath test. Further, the circuit court’s judgment
affirming the director’s decision to suspend Mr. Wilmoth’s license pursuant to section
302.505 is supported by substantial evidence and is not against the weight of the evidence.
Therefore, the circuit court’s judgment is affirmed.
