Respondent,
v.
SHANE NMI AHEARN, UNPUBLISHED OPINION
Appellant.
SUTTON, J. – Shane Nmi Ahearn appeals his bench trial convictions for unlawful possession
of a controlled substance and driving under the influence (DUI). He challenges various findings
of fact and conclusions of law from both the suppression hearing and the bench trial, and argues
that (1) the trial court erred when it denied his motion to suppress because the trooper lacked
probable cause, and (2) the evidence does not support his DUI conviction. We affirm.
FACTS
I. BACKGROUND1
On February 2, 2014, at about 3:15 AM, Washington State Patrol Trooper Kyle Dahl
observed the vehicle Ahearn was driving swerving within its lane of travel, crossing the fog line,
and then swerving into the adjacent lane. At one point, the vehicle crossed over the fog line and
1
These facts are drawn from the trial court’s findings of fact and conclusions of law related to the
CrR 3.6 suppression motion and the trial court’s CrR 6.1(d) findings of fact and conclusions of
law related to the bench trial. To the extent Ahearn does not challenge these findings, they are
verities on appeal. State v. Broadaway, 133 Wn.2d 118, 131, 942 P.2d 363 (1997). We address
Ahearn’s specific challenges to the findings below.
No. 46645-7-II
continued to drive for about 100 yards before returning to its lane. When the vehicle eventually
exited the highway, it did not stop at the stop sign at the end of the exit ramp and then it turned left
without signaling.
Trooper Dahl activated his emergency lights to pull Ahearn over. Ahearn continued to
drive for about a quarter of a mile, passing several safe places to stop, before pulling over.
When Trooper Dahl told Ahearn to roll down his window, Ahearn “struggle[d] excessively
with the window switches.” Clerk’s Papers (CP) at 124. Ahearn was “sweating profusely, to the
extent [the trooper] was concerned for [Ahearn’s] health and asked if [Ahearn] was alright.”
CP at 124. Ahearn told Trooper Dahl that he had just showered, but he did not say that was the
reason he was sweaty.2 Trooper Dahl did not notice anything external, such as it being hot inside
the vehicle, which could have explained Ahearn’s profuse sweating.
Once out of the vehicle, Ahearn “struggled to keep the driver’s door from closing on him
while trying to put his jacket on, and he struggled with the buttons on the jacket.” CP at 125.
Ahearn also stumbled, “on nothing apparent,” as he walked toward the front of his vehicle. CP
at 125, 162. Throughout their contact, Trooper Dahl noticed that Ahearn’s speech “was fast and
broken” and that “his eyes were watery and bloodshot.” CP at 125, 162.
Ahearn consented to take field sobriety tests. Trooper Dahl administered a portable breath
test, the horizontal gaze nystagmus (HGN) test, the walk and turn test, the one-leg stand test, and
2
The trial court found these facts—that Ahearn told Trooper Dahl he had showered but did not
say the shower was why he was sweating—when addressing the suppression motion; the trial court
did not include these facts in its findings of fact related to the bench trial. Accordingly, we do not
consider these facts in our sufficiency of the evidence analysis.

No. 46645-7-II
the Romberg balance test.3 Ahearn’s HGN test provided “zero clues,” and a portable breath test
sample he provided registered .000. CP at 125, 163.
The results of the walk and turn test were “questionable,” but the test was administered on
a grade, which did not comply with test standards. CP at 125, 163. Ahearn also performed poorly
on the one-leg stand test and the Romberg balance test.4 Throughout the tests, Ahearn exhibited
“violent body tremors,” he “swayed in a circular motion when standing still,” and he “continued
to sweat despite the cold.” CP at 126, 162. He also “walked very fast during the [w]alk and [t]urn
test.” CP at 126, 162.
Trooper Dahl concluded that Ahearn’s physical movements, tremors, swaying, rapid
speech and walking, and profuse sweating suggested he was affected by a stimulant.5 Trooper
Dahl arrested Ahearn for suspicion of DUI.
After his arrest, Ahearn consented to a search of his vehicle. During the search, Trooper
Dahl found a syringe containing a clear liquid, later identified as methamphetamine.

We describe these tests in more detail below.

Ahearn challenges the trial court’s findings with regard to these tests; we discuss these findings
in more detail below.
5
Trooper Dahl testified to this at the suppression hearing, but he did not include this statement in
his incident report, which was submitted as evidence at the bench trial. Accordingly, we consider
this fact when evaluating the denial of the suppression motion, but not when evaluating the bench
trial conviction.

No. 46645-7-II
II. PROCEDURE
A. SUPPRESSION MOTION
The State charged Ahearn with unlawful possession of a controlled substance
(methamphetamine), and DUI. Ahearn moved to suppress all of the evidence obtained after the
stop. He primarily argued that Trooper Dahl lacked probable cause to arrest him for the DUI.
Trooper Dahl; Ahearn; and Thomas Missel, Ahearn’s expert on DUI investigations, testified at the
suppression hearing.
In addition to testifying about the facts above, Trooper Dahl testified that he administered
the walk and turn test, the one-leg stand test, and the Romberg balance test. Trooper Dahl testified
that the walk and turn test requires the subject to walk a straight line by placing one foot in front
of the other heel-to-toe for nine steps, to turn around by keeping their front foot on an imaginary
line and taking a series of small steps around the front foot with their back foot, and to return using
the heel-to-toe method. Ahearn struggled to keep his balance when listening to the instructions,
turned the wrong way at the turn, and failed to take heel-to-toe steps several times.
Trooper Dahl admitted that this test was designed to be conducted on level ground and that
there was a noticeable grade where this test occurred. But he did not think the grade was sufficient
to affect this test, and he commented that the grade had nothing to do with Ahearn’s executing the
turn incorrectly. Because this test was validated on level ground, however, Trooper Dahl took the
grade into consideration when evaluating Ahearn’s performance. He also stated that in his training
he learned that he could still “consider” the test even if it was performed on a grade, but it would
not be “weighted as heavily as if it was done on level ground.” 1 Report of Proceeding (RP) (July
4
No. 46645-7-II
21, 2014) at 46. Trooper Dahl specifically testified that Ahearn “performed poorly” on this test.
1 RP (July 21, 2014) at 42.
Trooper Dahl next testified that the one-leg stand test requires the subject to stand on one-
leg, to raise the other foot about six inches off of the ground, and to “count by one thousands until”
the officer tells them to stop. 1 RP (July 21, 2014) at 46. Trooper Dahl testified that during this
test, Ahearn swayed and he counted “one, two, three,” rather than “one one-thousand, two one-
thousand, three one-thousand,” as he had been instructed to do. 1 RP (July 21, 2014) at 47. While
the way the subject counts is not a “standardized clue” for this test, Trooper Dahl considered
Ahearn’s failure to count as instructed because it related to his ability to follow instructions. 1 RP
(July 21, 2014) at 47-48.
Trooper Dahl testified that during the Romberg balance test, the subject is instructed to
close his eyes and tilt his head back; to estimate thirty seconds “in [his] mind;” and to tilt his head
forward, open his eyes, and say stop after 30 seconds. 1 RP (July 21, 2014) at 50-51. Trooper
Dahl also stated that Ahearn’s time estimation was “pretty close,” at 34 seconds. 1 RP (July 21,
2014) at 51. But Trooper Dahl once again observed that Ahearn had trouble following the
instructions because he started counting out loud and had to be reminded to count to himself.
Missel testified about the validity of the field sobriety tests for detecting alcohol use. He
testified that to determine whether a subject has a blood alcohol level of over .08, there are a
minimum number of clues for each test that the examiner must observe for each test: four out of
six clues for the HGN test, two or more clues for the walk and turn test, and two or more clues for
the one-leg-stand test. And he testified that validation of these tests by the National Highway
5
No. 46645-7-II
Traffic Safety Administration (NHTSA) would give users the “percentage of accuracy rate” of
probability that a subject was impaired. 1 RP (July 21, 2014) at 120.
Throughout this testimony, Missel emphasized that the validation studies related to these
tests were only accurate for tests performed following the NHTSA protocols. He also testified that
a trooper would have the opportunity to make a lot of observations outside of the testing that might
suggest impairment, even though those observations would not be supported by validation studies.
In addition, he testified that there had never been any validation studies on whether the field
sobriety tests Trooper Dahl administered were effective in detecting drug use.
As to the particular tests here, Missel testified that he was concerned that the walk and turn
test had been administered on a slope of about 10 percent grade. He opined that the slope made
the test results “invalid.” 1 RP (July 21, 2014) at 112. But he also noted that, while the
observations made during the test would lack the certainty of a properly performed test, the trooper
could “still [make] observations.” 1 RP (July 21, 2014) at 108, 120, 131.
Missel also testified that the Romberg balance test was used in the drug recognition
program. The subject’s time accuracy was one factor, but the tester would also watch for “body
sway,” tremors, and other factors. 1 RP (July 21, 2014) at 123. He testified that even an
unvalidated test, such as the Romberg balance test, could provide additional “observations” that
would be helpful. 1 RP (July 21, 2014) at 125.
Missel then testified that the slope would not affect the one-leg stand. He testified that
Trooper Dahl did not, however, observe enough clues on the one-leg stand to show impairment
because Ahearn’s internal clock estimate “fell within the acceptable range of 25 to 35 seconds.”
1 RP (July 21, 2014) at 131. He stated that for the officer to be able to say with 65 percent accuracy
6
No. 46645-7-II
that a subject was impaired, the subject would need to show two clues. Missel admitted that the
trooper could consider the one observed clue in conjunction with other observations when
determining if the subject was impaired.
Based on this testimony and the facts above, the trial court found that Trooper Dahl had
probable cause to arrest Ahearn for DUI. The trial court denied the motion to suppress.
B. BENCH TRIAL ON STIPULATED FACTS
Following the suppression hearing, Ahearn waived his right to a jury trial and agreed to a
bench trial based on the law enforcement reports and stipulated facts. Specifically, he stipulated
that the crime lab had tested the contents of the syringe found in his vehicle and had determined
that the syringe contained methamphetamine, and he “adopt[ed] the testimony of his expert
witness, Thomas Missel, who testified in the CrR 3.6 hearing that standardized field sobriety tests
are a valuable tool in drug related DUI investigations and provide observational information for
law enforcement.”6 CP at 110.
In addition to the facts set out above, Trooper Dahl stated in his report that when he first
contacted Ahearn, Ahearn stated that he had not been drinking alcohol and that he had not “taken
any medication or any drug[s].” CP at 115. Trooper Dahl also wrote that when he administered
the field sobriety tests he observed that (1) Ahearn’s eyes were blood shot and watery, (2) Ahearn
was having violent body tremors, (3) Ahearn was swaying in a circular motion, and (4) Ahearn
continued to sweat even though it was colder outside of his car.
6
For purposes of our analysis, we will presume that this allowed the trial court to consider Missel’s
testimony in its entirety.
7
No. 46645-7-II
Trooper Dahl’s report also described Ahearn’s performance on three field sobriety tests:
Walk and Turn Test:
While giving Ahearn the instructions[,] Ahearn started the test early twice. Ahearn
also lost his balance and had to step offline to his right to catch his balance. Once
Ahearn began the test[,] Ahearn missed heel to toe on steps five[,] six[,] and seven
on his first nine steps. Ahearn the[n] made a quick turn in one motion to his right.
On Ahearn’s second nine steps[,] Ahearn missed heel to [t]oe on steps five, six,
seven, eight, and nine. Ahearn also used his arms for balance during the test.
Ahearn also took his steps at a faster than normal pace.
One Leg Stand:
For this test[,] Ahearn stood on his right leg and raised his left foot. During the test
Ahearn swayed and had body tremors. Ahearn also did not count as he was
instructed, Ahearn counted one, two three etc. instead of one-thousand and one,
one-thousand and two etc.
Romberg Balance:
For the test Ahearn estimated 30 seconds in 34 actual seconds. Ahearn began
counting out loud by thousands until I reminded him to count in his head. After
Ahearn finished the test, I asked Ahearn how long he thought that was, Ahearn
stated he thought it was about 30 seconds. I asked Ahearn how he counted, Ahearn
stated he just counted and that he imagined a stopwatch in his head. I observed
Ahearn to have violent body tremors, and sway in a circular motion.
CP at 116.
Trooper Dahl further stated that Ahearn continued to sweat while being transported.
Ahearn refused to consent to a blood draw and none was taken.
The trial court filed written findings of fact and conclusions of law under CrR 6.1(d). These
findings are consistent with the facts above.7 Based on these facts, the trial court concluded that
Ahearn was guilty of DUI because he operated a motor vehicle “while his ability to drive was
impaired by a drug.” CP at 163. The trial court also found Ahearn guilty of unlawful possession
of a controlled substance.
7
We address the specific CrR 6.1(d) findings that Ahearn challenges in more detail below.
8
No. 46645-7-II
Ahearn appeals the denial of his suppression motion and his bench trial conviction for DUI.
ANALYSIS
I. SUPPRESSION MOTION
Ahearn first argues that the trial court erred when it denied his suppression motion. He
contends that Trooper Dahl lacked probable cause to arrest him.8 We disagree.
A. LEGAL STANDARDS
“We review a trial court’s denial of a CrR 3.6 suppression motion to determine whether
substantial evidence supports the trial court’s challenged findings of fact and, if so, whether the
findings support the trial court’s conclusions of law.” State v. Cole, 122 Wn. App. 319, 322-23,
93 P.3d 209 (2004) (citing State v. Mendez, 137 Wn.2d 208, 214, 970 P.2d 722 (1999)). “We
review conclusions of law, including mischaracterized ‘findings,’ de novo.” Cole, 122 Wn. App.
at 323.
B. CHALLENGES TO FINDINGS
1. CrR 3.6 Finding of Fact No. XVII
Ahearn assigns error to CrR 3.6 finding of fact no. XVII, which states:
That Trooper Dahl testified the Defendant performed poorly on the three
physical dexterity and divided attention tests. He testified that throughout the
contact and during the [field sobriety tests] the Defendant had violent body tremors.
He swayed in a circular motion when standing still. He walked very fast during the
Walk and Turn test. He continued to sweat despite the cold and to speak in a fast,
broken manner.
8
Ahearn also argues that the syringe evidence should have been suppressed because it was fruit of
the poisonous tree following the unlawful arrest. Because we hold that the arrest was based on
probable cause, this argument fails.
9
No. 46645-7-II
CP at 125-26. Ahearn’s arguments address only the first two sentences of this finding, accordingly,
we address only those portions of this finding. RAP 10.3(a)(6); State v. Goodman, 150 Wn.2d
774, 782, 83 P.3d 410 (2004).
Ahearn first challenges the portion of CrR 3.6 finding no. XVII stating, “Trooper Dahl
testified the Defendant performed poorly on the three physical dexterity and divided attention
tests.” CP at 125-126. Regardless of whether the trial court’s finding that Ahearn “performed
poorly” on the tests was supported by the record, it is ultimately irrelevant because, as discussed
below, the trial court’s conclusion that the State established probable cause is supported by other
findings. Thus, we do not address this issue further.
Ahearn also argues that the trial court should not have considered Ahearn’s “body tremors”
as evidence of impairment because these “severe shiver[s]” could be contributed to the fact Ahearn
had been sweating and was outside in the cold. Br. of Appellant at 15-16. To the extent this
argument relates to CrR 3.6 finding of fact no. XVII, the trial court found that Trooper Dahl
testified at the suppression motion hearing that throughout the contact and during the testing
Ahearn had violent body tremors. This finding is amply supported by Trooper Dahl’s testimony.
2. CrR 3.6 Finding of Fact No. IXX
Ahearn next assigns error to CrR 3.6 finding of fact no. IXX, which states:
That Defendant’s physical movements, violent body tremors, swaying, rapid
speech and walking, profuse sweating, and other indicators did suggest the
Defendant was affected by a stimulant.
CP at 126.
As noted above, Ahearn argues that the trial court should not have considered Ahearn’s
“body tremors” as evidence of impairment because these “severe shiver[s]” could be contributed
10
No. 46645-7-II
to the fact Ahearn had been sweating and was outside in the cold. Br. of Appellant at 15-16.
Ahearn is correct that his sweating and the cold temperature could have contributed to his shivers
or tremors. But Trooper Dahl testified that while the cold may have contributed to Ahearn’s
shivering, based on his training and experience, he did not believe the cold caused the shivers
because of “the severity of them.” 1 RP (July 21, 2014) at 92. This testimony supports the trial
court’s consideration of this factor as suggestive of Ahearn being affected by a stimulant.
Additionally, even if the cold had contributed to Ahearn’s shivers or tremors, the trial court
considered several additional factors, such as Ahearn’s balance problems, profuse sweating, fast
speech, and attention issues, that suggested Ahearn was affected by a stimulant and the absence of
this single factor would not affect this finding.9
C. CHALLENGES TO CRR 3.6 CONCLUSIONS OF LAW
Ahearn next challenges the trial court’s CrR 3.6 legal conclusion that the State established
probable cause.10 Again, we disagree.
9
Ahearn also appears to argue that Trooper Dahl did not contradict Ahearn’s testimony that
visibility was poor because of foggy conditions, suggesting that the trial court should have made
a finding on this issue. Because Ahearn does not assign error to finding of fact no. IV from the
suppression hearing findings, which describes Ahearn’s driving, we do not address this assertion.
Furthermore, to the extent Ahearn is attempting to argue that his erratic driving was not enough to
establish probable cause to suspect he was driving while impaired, it is still a factor we may
consider when examining the totality of the circumstances.
10
Ahearn assigns error to portions of findings of fact no. IXX and no. XXIV that relate to the trial
court’s probable cause finding. Because the probable cause findings are in fact legal conclusions,
we treat them as such on appeal. State v. Chamberlin, 161 Wn.2d 30, 40-41, 162 P.2d 389 (2007);
Cole, 122 Wn. App. at 323. Ahearn also assigns error to conclusion of law no. III, which is the
trial court’s conclusion that Trooper Dahl had probable cause to arrest Ahearn for DUI.
11
No. 46645-7-II
Whether probable cause exists is a legal question we review de novo. State v. Grande,
164 Wn.2d 135, 140, 187 P.3d 248 (2008). “Probable cause exists where the facts and
circumstances within the arresting officer’s knowledge and of which the officer has reasonably
trustworthy information are sufficient to warrant a person of reasonable caution in a belief that an
offense has been committed.” State v. Terrovona, 105 Wn.2d 632, 643, 716 P.2d 295 (1986).
Probable cause requires more than “a bare suspicion of criminal activity.” Terrovona, 105 Wn.2d
at 643. But it does not require facts that would establish guilt beyond a reasonable doubt. State v.
Conner, 58 Wn. App. 90, 98, 791 P.2d 261 (1990). The probable cause determination “rest[s] on
the totality of facts and circumstances within the officer’s knowledge at the time of the arrest.”
State v. Fricks, 91 Wn.2d 391, 398, 588 P.2d 1328 (1979).
The facts show that before Trooper Dahl arrested Ahearn, Ahearn (1) was weaving in and
out of his lane while driving, (2) failed to stop at a stop sign, (3) turned without signaling, (4) failed
to pull over immediately when Trooper Dahl put on this emergency lights despite passing several
areas where he could have safely stopped, (5) struggled “excessively” with the window controls
when asked to roll down the vehicle’s window, 11 (6) was sweating profusely for no apparent
external reason, (7) struggled to keep the driver’s side door from closing on him while attempting
to put on a jacket, (8) struggled to button his jacket, (9) stumbled, apparently on nothing, when
walking to the front of his car, (10) “exhibited “violent body tremors,” “swayed in a circular motion
11
CP at 124 (3.6 FF IX).
12
No. 46645-7-II
when standing still,” and “walked very fast during the [w]alk and [t]urn test,” 12 , 13
and (11)
continued to sweat despite being outside in the cold. In addition, Ahearn’s “speech throughout the
contact was fast and broken and . . . his eyes were watery and bloodshot,” and Trooper Dahl
concluded that Ahearn’s physical movements and behavior suggested he was affected by a
stimulant. CP at 125.
While any one of these facts may not have given rise to probable cause, the totality of these
circumstances demonstrated that Ahearn was having physical symptoms, such as balance
problems, profuse sweating, tremors, and fast speech, as well as attention issues. These factors
demonstrate that probable cause existed to believe Ahearn was driving under the influence.
Ahearn also asserts that many of the facts Trooper Dahl relied on could have been
explained by it being 3:00 AM, Ahearn having been awake all night and not being appropriately
dressed for the weather, and Ahearn being uncomfortable in the trooper’s presence. While there
could be alternative explanations for Ahearn’s condition and reactions, the State was not required
to prove beyond a reasonable doubt that Ahearn was impaired or that impairment was the only
possible explanation in order to establish probable cause. See Conner, 58 Wn. App. at 98. And
given the numerous factors described above that suggested some level of impairment, the trial
court did not err when it concluded that the trooper had probable cause.
12
CP at 126.
13
While this test was not administered properly, Missel testified that Trooper Dahl could still make
“observations” that would be relevant to whether Ahearn was driving under the influence. 1 RP
(July 21, 2014) at 108, 120, 125, 131, 134-36.
13
No. 46645-7-II
Ahearn also argues that the State did not show that Trooper Dahl offered him the
opportunity to undergo an evaluation by a drug recognition expert and that the State’s failure to do
this “must be construed in Mr. Ahearn’s favor.” Br. of Appellant at 17. In support of this
argument, Ahearn cites State v. Armenta, 134 Wn.2d 1, 14, 948 P.2d 1280 (1997), which states
only that if the trial court does not make a finding on a factual issue, we presume that the party
with the burden of proof failed to sustain their burden on this issue. Armenta does not address
whether Trooper Dahl was required to offer Ahearn the opportunity to seek an evaluation by a
drug recognition expert before determining probable cause. Because Ahearn cites no authority
supporting his argument, we do not consider it further. RAP 10.3(a)(6).
Because the factors described above demonstrate that probable cause existed to believe
Ahearn was driving under the influence, we hold that the trial court did not err when it denied
Ahearn’s suppression motion.
II. SUFFICIENCY
Ahearn next argues that the evidence is insufficient to support his DUI conviction. 14
Specifically, he argues that portions of the trial court’s CrR 6.1(d) findings of fact no. VIII and
no. IX are not supported by substantial evidence and that the trial court erred in concluding that
the State had proved he had been driving under the influence of drugs. We disagree.
14
We note that while some of the analysis in this section appears repetitive, we cannot just rely on
the CrR 3.6 analysis because the trooper’s testimony in the CrR 3.6 hearing was not stipulated to
for the bench trial. Thus, the facts in this later section rely only on the trooper’s written statements,
which were not as in depth as the CrR 3.6 hearing testimony, and there are some subtle differences.
14
No. 46645-7-II
A. LEGAL STANDARDS
When challenging the sufficiency of the evidence, the defendant admits the truth of the
State’s evidence and all inferences that may reasonably be drawn from them. State v. Stevenson,
128 Wn. App. 179, 192, 114 P.3d 699 (2005). When a defendant challenges the sufficiency of
the evidence, the proper inquiry is “whether, after viewing the evidence in the light most
favorable to the State, any rational trier of fact could have found guilt beyond a reasonable
doubt.” State v. Salinas, 119 Wn.2d 192, 201, 829 P.2d 1068 (1992).
Following a bench trial, we review a trial court’s decision to determine whether substantial
evidence supports any challenged findings and whether the findings in turn support the conclusions
of law. Stevenson, 128 Wn. App. at 193. “Substantial evidence is evidence sufficient to persuade
a fair-minded, rational person of the finding’s truth.” Stevenson, 128 Wn. App. at 193.
Unchallenged findings of fact are verities on appeal, and we do not review the fact finder’s
credibility determinations. Stevenson, 128 Wn. App. at 192 n.11, 193. “Circumstantial evidence
provides as reliable a basis for findings as direct evidence.” State v. Myers, 133 Wn.2d 26, 38,
941 P.2d 1102 (1997). And we review conclusions of law de novo. Stevenson, 128 Wn. App.
at 193.
B. CRR 6.1(d) FINDING OF FACT NO. VIII
Finding of fact no. VIII states:
That the Defendant performed Field Sobriety Tests (FSTs); the Gaze
Nystagmus test, the Walk and Turn test, the One Leg Stand test, and the Romberg
Balance [t]est. That the defendant performed poorly on all three physical dexterity
and divided attention tests. That the Defendant had violent body tremors
throughout the contact and during the FSTs. He swayed in a circular motion when
standing still. He walked very fast during the Walk and Turn test. He continued to
sweat despite the cold and to speak in a fast, broken manner. That the results of the
15
No. 46645-7-II
Walk and Turn are questionable, as there was as slope to the ground, approximated
at a 10% grade, which does not comport with the NHTSA standards. That the
Defendant showed zero clues on the HGN test and provided a portable breath test
sample of .000.
CP at 162-63. Ahearn argues that the evidence does not support the portion of this finding stating
that he “‘performed poorly’ on the field sobriety tests.” Suppl. Br. of Appellant at 2. Even
presuming that the trial court’s conclusion that Ahearn “performed poorly” on the field sobriety
tests was incorrect, this error would be harmless because, as discussed below, the remaining
findings support the trial court’s conclusions of law.
C. CRR 6.1(d) FINDING OF FACT NO. IX
Finding of fact no. IX states:
That the Defendant’s physical movements, observed while he was
performing field sobriety tests, included violent body tremors, swaying, rapid
speech and walking, profuse sweating, and other indicators that suggest the
Defendant was affected by a stimulant.
CP at 163. Ahearn argues that the evidence does not support the trial court’s conclusion that
Ahearn’s physical movements and other indicators “suggest[ed]” that he was affected by a
“stimulant.” Suppl. Br. of Appellant at 3.
Ahearn is correct that Trooper Dahl’s report did not state that these factors suggested
Ahearn was affected by a stimulant. Trooper Dahl stated only that these factors, plus his other
observations during the stop, led him to believe that Ahearn was unsafe to drive. Thus, Ahearn is
correct that this finding is not supported by the record. But this error is harmless because the
remaining findings support the trial court’s conclusions of law.
16
No. 46645-7-II
D. CRR 6.1(d) CONCLUSION OF LAW NO. II
Conclusion of law no. II provides:
That the Defendant is guilty of [DUI] because he operated a motor vehicle
on public roadways in Kitsap County, Washington on February 2, 2014 while his
ability to drive was impaired by a drug.
CP at 163 (emphasis added). Ahearn argues that this conclusion of law is actually a finding of fact
and that it is not supported by the stipulated evidence.
We disagree with Ahearn’s assertion that this is a finding of fact. Conclusion of law no. II
is, instead, the trial court’s conclusion that the State has proved the elements of the DUI. Thus,
we address this as the trial court labeled it, as a conclusion of law.
Ahearn argues that the evidence was not sufficient to support the verdict because it did not
establish that he was under the influence of drugs or that he was impaired. We disagree with
Ahearn’s argument and hold that the trial court’s bench trial findings support this conclusion of
law.
As to Ahearn’s impairment, the unchallenged findings of fact established that he (1) was
unable to maintain his lane of travel while on the highway, (2) ran a stop sign when he exited the
highway, (3) failed to signal when he turned, (4) struggled with simple tasks such as unrolling his
window and putting on his jacket, and (5) exhibited physical symptoms including excessive

sweating, body tremors, and lack of attention during the field sobriety tests. These facts support
the conclusion that he was impaired.15
As to the cause of this impairment, the trial court’s unchallenged bench trial findings
mention no evidence suggesting that Ahearn was impaired by alcohol. But the unchallenged
findings also show that the trooper found drugs in Ahearn’s vehicle. Ahearn’s obvious impairment
coupled with the presence of drugs in the car provide sufficient circumstantial evidence that the
impairment was caused by drug use.16 Thus, the trial court’s findings of fact support its conclusion
that that the State had proved the DUI charge.
15
Ahearn argues that his inability to maintain his lane of travel, his failure to stop, and his failure
to signal were not enough to establish his driving was impaired because he was driving on empty
roads at 3:00 AM. But these facts are not the only facts suggesting impairment.
16
Ahearn argues that the evidence is insufficient because the trooper did not confirm the drug use
with a blood test or examination by a drug recognition expert. But such direct evidence is not
required. See State v. Woolbright, 57 Wn. App. 697, 701, 789 P.2d 815 (1990) (“[C]hemical tests
are neither necessary nor required to prove intoxication.”).
Ahearn also argues that the mere presence of a syringe containing methamphetamine and
an empty syringe in the center console was not sufficient to establish that Ahearn used the drugs
because he was homeless and could have just been storing the syringes in the car. This argument
goes beyond the trial court’s findings of fact, so we do not consider it further.
Ahearn also cites State v. Gillenwater, 96 Wn. App. 667, 980 P.2d 318 (1999), but this
case is inapplicable here. At best, Gillenwater suggests that to establish guilt of DUI beyond a
reasonable doubt, the State must present more than just evidence that the defendant had been
drinking. See 96 Wn. App. at 671. But the Gillenwater court was dealing with a probable cause
issue that involved the fact that no one had observed any erratic driving by the defendant, it was
not addressing whether the presence of alcohol in the vehicle could establish a DUI without any
direct evidence that the defendant had ingested it.

No. 46645-7-II
CONCLUSION
Ahearn fails to show that the trial court erred in denying his motion to suppress or that his
bench trial conviction for DUI was improper. Accordingly, we affirm his convictions.
A majority of the panel having determined that this opinion will not be printed in the
Washington Appellate Reports, but will be filed for public record in accordance with RCW 2.06.040,
it is so ordered.
