and, therefore, may not fully address the facts of the case or the panel's
decisional rationale. Moreover, such decisions are not circulated to the entire
court and, therefore, represent only the views of the panel that decided the case.
A summary decision pursuant to rule 23.0 or rule 1:28 issued after February 25,

COMMONWEALTH OF MASSACHUSETTS

APPEALS COURT

25-P-236

COMMONWEALTH

vs.

WESLY AGUILAR-VALENZUELA.

MEMORANDUM AND ORDER PURSUANT TO RULE 23.0

The defendant was convicted after a jury trial of operating

under the influence of alcohol (OUI) in violation of G. L.

c. 90, § 24 (1) (a) (1). A judge of the District Court found

the defendant not responsible for a related civil infraction.

On appeal, the defendant challenges the admission of testimony

by two State police troopers about the defendant's "impairment"

and asserts that he was prejudiced when the trial judge did not

give a limiting instruction sua sponte about this testimony. We

affirm.

Background. On the date in question, troopers with the

Massachusetts State police had established a sobriety checkpoint

in Springfield. The defendant entered the checkpoint area and,
at a stop sign, encountered the first trooper, a "contact

officer," who had a "very short interaction" with the defendant.

At trial, this first trooper testified that he had eighteen

years of experience with the State police and had been trained

in motor vehicle stops, OUI detection, operating under the

influence, and standardized field sobriety testing. He

testified that the defendant had "red, glassy, bloodshot eyes"

and the trooper saw an open beer can in the defendant's lap.

The jury saw a video recording from this trooper's body-worn

camera (BWC), which was admitted in evidence. The first trooper

testified that his role was looking for "[s]igns of impairment,"

and explained that from "speaking with this operator and having

contact with him," the trooper "observed him to have the -- from

my training and experience, an indication of impairment or

consumption of alcoholic beverages, not impairment, besides the

red, glassy, bloodshot eyes, the open beer, [h]e seemed a bit

confused handing me his license right away when I didn't ask him

for it."

In the screening area, the defendant encountered the second

trooper. The second trooper had also been trained in motor

vehicle stops and "OUI," presumably the detection thereof. He

administered two standardized field sobriety tests to the

defendant, the nine-step walk and turn, and the one-legged

stand. The second trooper testified that, in administering

2
these tests, he was "looking for impairment," and described

various signs or "clues" he had been taught to look for.

The trooper testified that, during the nine-step walk and

turn test, the defendant "swayed his arms, he started the test

too soon, he stopped in the middle of the test" and he did not

stay on the "imaginary line." The second trooper explained

that, "to detect impairment," he needed only "two out of the

eight" clues, and he had observed four. After describing how he

had instructed the defendant on the one-legged stand, the second

trooper described how the defendant had dropped his foot at the

eighteen-second mark, raised his arms for balance, and swayed

his body before putting his foot down. The second trooper

explained that there were four clues of impairment in that test

and he had seen the defendant exhibit three of them. Throughout

the testimony, the prosecutor often framed her questions in

terms of "cues" or "clues" or "signs" of "impairment" and the

second trooper responded, often using the same terms.

The jury also saw BWC footage of the instructions and the

field sobriety tests. On that video, the jury could see the

defendant's car, which was parked "slightly at an angle" to the

marked parking space in which the defendant was supposed to

park.

Discussion. Citing Commonwealth v. Canty, 466 Mass. 535

(2013), the defendant asserts that the conviction rests on

3
improper lay opinion testimony by the two troopers about the

"ultimate issue" in the case, namely that the defendant's

ability to operate his motor vehicle safely was impaired by

alcohol consumption. We are not persuaded.

Because the defendant did not object to this testimony at

trial, we review this claim to determine whether there was

error, and if so, whether the error created a substantial risk

of a miscarriage of justice. See Commonwealth v. AdonSoto, 475

Mass. 497, 504 (2016). In so doing, we ask whether any error

was "sufficiently significant in the context of the trial to

make plausible an inference that the [jury's] result might have

been otherwise but for the error" (citation omitted).

Commonwealth v. Alphas, 430 Mass. 8, 13 (1999).

We discern no error here. A lay witness may "offer his

opinion regarding a defendant's level of sobriety or

intoxication." Canty, 466 Mass. at 544. The defendant makes

much of the troopers' use of the word "impairment" to describe

the defendant, but "[t]he rule that witnesses in describing

conduct should tell what they saw and heard does not foreclose

the use of words of summary description," id., quoting Kane v.

Fields Corner Grille, Inc., 341 Mass. 640, 647 (1961), and

"'[p]robably impaired,' while not a particularly precise phrase,

is no worse than many of the alternatives (e.g., 'buzzed,'

4
'tipsy') to describe a modest level of inebriation." Canty,

supra.

The question is not whether the troopers used a forbidden

word, but whether they opined on "whether the defendant's

consumption of alcohol diminished the defendant's ability to

operate a motor vehicle safely" (quotation and citation

omitted). Canty, 466 Mass. at 542. Such testimony

impermissibly "comes close to an opinion as to whether the

defendant is guilty." Id. Having reviewed the challenged

testimony, we are satisfied that the judge did not err by not

sua sponte striking it, or offering a corrective instruction, or

otherwise addressing the testimony in the moment. The

witnesses, perhaps following the prosecutor's lead, used

"impairment" as a synonym for "inebriation" (or being "buzzed,"

or "tipsy") and did not opine as to the defendant's ability

safely to operate the vehicle. Indeed, defense counsel picked

up the nomenclature and used it, too. See Commonwealth v.

Dodgson, 80 Mass. App. Ct. 307, 313 (2011) (lack of objection

some indication that tone and manner of statement did not appear

at trial to be as prejudicial as argued on appeal).

Having discerned no error in the testimony, we are

similarly unmoved by the assertion that the prosecutor, in her

jury addresses, exacerbated any error. It was evident from the

testimony and the BWC footage that the second trooper "decided"

5
to arrest the defendant after conducting the field sobriety

tests, so the prosecutor's statement of that fact lent little to

the jury's consideration. And, while she used variations of the

term "impaired" while describing what the troopers were looking

for, the prosecutor stopped short of saying that the troopers'

opinions indicated that the defendant was so impaired as not to

be able to operate his vehicle safely. In considering the

evidence and argument, we are also mindful that the jury had the

benefit of BWC footage reflecting both troopers' interactions

with the defendant, and that the judge correctly instructed the

jury as to their burdens, both in assigning weight to witness

testimony and in weighing other evidence. The jury were also

instructed that questions alone, opening statements, and closing

arguments were not evidence.

Judgment affirmed.
