BEFORE: SHOGAN, J., DUBOW, J., and PELLEGRINI*, J.
OPINION BY PELLEGRINI, J.: FILED MAY 06, 2019
Sarah E. Taylor (Taylor) appeals from the judgment of sentence entered
on February 28, 2018, in the Court of Common Pleas of York County following
her convictions of driving under the influence of drugs (DUI) and endangering
the welfare of a child (EWOC).1 As to the EWOC count, Taylor was sentenced
to a prison term of six to 12 months. As to the DUI count, she received an
intermediate sentence which included a concurrent prison term of six months,
followed by six months of house arrest. On appeal, she argues that the trial
court erred in excluding a portion of her expert witness’s testimony. We find

merit in her claim, vacate the judgment of sentence, and remand the case for
a new trial on all counts.
I.
The pertinent facts in this appeal are undisputed. Moments prior to the
subject accident, Taylor was driving her car about 20 miles per hour over the
speed limit. Her 18-month-old child was secured in a car seat. When the
traffic light turned red, Taylor had to break abruptly and she nearly rear-ended
a stopped vehicle in front of her. A few seconds after the light turned green,
Taylor rapidly accelerated her car over a nearby curb and crashed into a utility
pole located about 100 feet from the road.
Another motorist who saw the accident occur pulled over next to Taylor’s
car and approached on foot to offer help. Taylor also got out of her car and
told the motorist that she was not injured. Her child was also unharmed.
While speaking with the motorist, Taylor attempted to shut her car door, but
the motorist stopped it from shutting because it could have hit the child’s
outstretched arm.
Officer Joshua Crimmel arrived at the scene of the accident a few
minutes later. He observed that Taylor had bloodshot eyes and slurred
speech, but she did not smell of alcohol. She also appeared to be confused
and very tired. The officer had Taylor perform two standard field sobriety
tests – walking in a straight line and walking and turning 180 degrees.
According to the officer, Taylor performed poorly on the tests due to trouble
-2-
J-S22045-19
with balancing herself and following his directions. She repeatedly swayed
her body, used her arms to keep steady, and started the tests before being
prompted to do so.
The officer arrested Taylor on suspicion of DUI and EWOC. While in
custody, she admitted to taking Adderall and Xanax, but could not say the
amounts or how long before the accident they had been ingested. She denied
having any injuries or medical conditions that could have affected her ability
to operate a motor vehicle. The Commonwealth did not allege that Taylor was
impaired by alcohol and no blood test result was admitted into evidence.
Taylor declined medical treatment and she bore no trace of serious physical
injury.
At trial, a central point of dispute as to the DUI and EWOC charges was
whether Taylor was impaired by a controlled substance at the time she
crashed her car. The Commonwealth relied heavily on the arresting officer’s
testimony about Taylor’s accident and how she performed on the field sobriety
tests. The officer testified at length regarding his expertise in administering
those exercises. Other than describing the scene of the car accident, almost
all of the officer’s testimony was focused on how poorly Taylor performed on
the tests. He testified that Taylor’s performance indicated impairment
due to drug use.
The defense attributed Taylor’s poor performance to a possible head
injury from the accident. The defense attempted to rebut the officer’s
-3-
J-S22045-19
testimony with the opinion of its own witness, Dr. Lawrence Guzzardi, a
medical toxicologist and physician. This witness planned to testify, in part,
that there is no scientific basis to rely on field sobriety tests to detect drug
impairment because they have only been validated to reveal intoxication from
alcohol.
In its 1925(a) opinion, the trial court summarized Dr. Guzzardi’s
qualifications:
Since 2009, he has limited his practice to forensic toxicology,
testifying about emergency medicine and toxicology. The doctor
has lectured on DUI and field sobriety testing and about drug
recognition experts. And he stated that he has published on field
sobriety testing. Dr. Guzzardi has reviewed the literature on field
sobriety testing and drug recognition experts in order to teach on
these subjects. Dr. Guzzardi estimated that he has testified
approximately ten times in York County about field sobriety
testing.
On cross-examination, Dr. Guzzardi testified that he never took
standardized field sobriety testing, nor had any of the subject -
matter training that officers have. Dr. Guzzardi has only read the
publications on the topic. As for the drug recognition expert
training, Dr. Guzzardi has not taken it. Despite his background of
medical training and neurologic training, Dr. Guzzardi is not
certified to give field sobriety tests.
[On re-direct], Dr. Guzzardi stated that he has looked over the
validation studies for standardized field sobriety tests, he has
written about the reliability and the neurological issues involved
with those tests, that he is familiar with the scientific accuracy of
those tests, and that he has lectured on the topic.
Trial Court Opinion, 12/17/18, at 7-8 (emphasis added, citations omitted).
The trial court qualified Dr. Guzzardi as an expert in toxicology and the
scientific basis for field sobriety tests. See Trial Transcript, 1/11/18, at 153-

J-S22045-19
54. Dr. Guzzardi testified without objection about how the exercises are
conducted and how a person’s blood-alcohol level may be correlated to
performance on them. He also testified that he had reviewed Taylor’s medical
history and confirmed that she had been prescribed Xanax and Adderall. He
noted that after using them as directed by a physician for 30 days, the
medications should have little to no side effects. Taylor had been prescribed
the medication for over 30 days prior to the accident, but there was no
evidence regarding what dosages she took.
As to the field sobriety tests, however, the trial court sustained the
Commonwealth’s objection to Dr. Guzzardi’s testimony about their utility for
detecting drug impairment:
Defense Counsel: Am I correct that [field sobriety tests] were
constructed to determine blood alcohol content.
Dr. Guzzardi: Yes. In fact -
Commonwealth: I would object, Your Honor.
Trial court: I think – let’s get to the point here. We’re sort of all
over the place. Ask the question he’s been called as an expert on,
and let’s move ahead. I’m not so interested in what happened
twenty years ago.
Defense Counsel: So, am I correct that these tests are made to
check blood alcohol?
Dr. Guzzardi: They were determined - they were determined to
do blood alcohol . . .
Commonwealth: Objection.
Trial court: I am going to sustain that objection.
-5-
J-S22045-19
Defense Counsel: To your knowledge, have these studies ever
been validated for drug impairment?
Dr. Guzzardi: They have never been validated for drug –
Commonwealth: Objection again, out of the scope of expertise.
Trial court: I will sustain the objection.
Trial Transcript, 1/11/18, at 162-65.
The jury found Taylor guilty of DUI and EWOC and she was sentenced
as outlined above. Her post-sentence motions for relief were denied. The
trial court stated in its 1925(a) opinion that exclusion was proper because Dr.
Guzzardi did not qualify as “an expert on field sobriety testing.” Rule 1925(a)
Opinion, 12/17/18, at 15. The trial court emphasized that Dr. Guzzardi’s lack
of practical experience precluded him from opining on “the methodology used
to construct standardized field sobriety testing procedures.” Id.
The trial court stated in the alternative that even if Dr. Guzzardi indeed
qualified as an expert in that area, any prejudice to Taylor was trivial due to
the testimony he was permitted to give about how drugs and alcohol may
affect a person’s body. Id. at 16. Further, the trial court found any error to
be harmless because Taylor’s pre-accident driving and post-accident behavior
were so suggestive of drug impairment that Dr. Guzzardi’s excluded testimony
would have had no effect on the trial’s outcome. Id. at 17.

In her appeal, Taylor asserts a single issue2 for our consideration:
Whether, at Sarah Taylor’s trial on charges based on impairment
by controlled substances, the trial court erred in barring defense
expert testimony that field sobriety testing, while validated to
detect blood alcohol concentration, had not been validated to
determine drug impairment.
Appellant’s Brief, at 4. Taylor requests a new trial as to both the DUI and
EWOC counts.
II.
First, the trial court erred in declining to qualify Dr. Guzzardi as an
expert in the methodology behind standard field sobriety tests. The witness
should have been permitted to testify that they have never been scientifically
validated as reliable indicators of drug impairment.3
____________________________________________
2 Taylor had asserted two additional grounds for relief in her Statement of
Issues Complained of on Appeal, but she presented only this one issue in her
brief. Appellant’s Brief, at 4.
3 This Court recently summarized the applicable standard of review as follows:
“‘[D]ecisions regarding admission of expert testimony, like other
evidentiary decisions, are within the sound discretion of the trial
court’ and ‘[w]e may reverse only if we find an abuse of discretion
or error of law.’” Hyrcza v. West Penn Allegheny Health Sys.,
Inc., 978 A.2d 961, 972 (Pa. Super. 2009) (quoting Smith v.
Paoli Memorial Hosp., 885 A.2d 1012, 1016 (Pa. Super. 2005)).
“The trial court abuses its discretion when it misapplies the law or
when a manifestly unreasonable, biased or prejudiced result is
reached.” Girard Trust Bank v. Remick, 258 A.2d 882 (Pa.
1969). Additionally, “for such evidentiary ruling to constitute
reversible error, it must have been harmful or prejudicial to the
complaining party. A party suffers prejudice when the trial court’s
-7-
J-S22045-19
The basis for the trial court’s ruling was that Dr. Guzzardi lacked the
practical experience necessary for qualification as an expert on the
methodology of field sobriety tests. That is, the trial court found it significant
that Dr. Guzzardi had never received training on how to administer the tests
and had never himself performed them.
But whether field sobriety tests have been validated has nothing to do
with practical experience. The rules of evidence do not require a witness to
have hands-on skills in a given area in order to testify as an expert on its
theoretical aspects. Rather, a witness who is “qualified as an expert by
knowledge, skill, experience, training, or education may testify in the form of
an opinion or otherwise” if their knowledge is “beyond that possessed by the
average layperson,” the knowledge “will help the trier of fact to understand
the evidence or to determine a fact in issue,” and “the expert’s methodology
is generally accepted in the relevant field.” Pa.R.E. 702.
Courts must apply a liberal standard when determining if a witness
qualifies as an expert in a particular area of study. See Miller v. Brass Rail
Tavern, Inc., 664 A.2d 525, 528 (Pa. 1995). “The test to be applied when
qualifying a witness ‘is whether the witness has any reasonable pretension to
____________________________________________
error could have affected the verdict.” [Reott v. Asia Trend, 7
A.3d 830, 839 (Pa. Super. 2010)].
Wright v. Residence Inn by Marriott, Inc., No. 3607 EDA 2017 (Pa. Super.
April 9, 2019) (some citations omitted).

specialized knowledge on the subject under investigation.’” Wright v.
Residence Inn by Marriott, Inc., No. 3607 EDA 2017 (Pa. Super. April 9,
2019) (citing id.) (emphasis in original). The witness need not possess “all of
the knowledge in a given field” but must only “possess more knowledge than
is otherwise within the ordinary range of training, knowledge, intelligence or
experience. If he does, he may testify and the weight to be given to such
testimony is for the trier of fact to determine in view of the expert’s particular
credentials.” Id.
Here, Dr. Guzzardi was going to testify that field sobriety tests were
developed to detect alcohol intoxication and that they had never been
validated as indicators of impairment due to drug use. He would have derived
this opinion from years of rigorous scholarship. The trial court noted that Dr.
Guzzardi had:
“lectured on DUI and field sobriety testing and about drug
recognition experts,”
“published on field sobriety testing . . . [and had] reviewed
the literature on field sobriety testing and drug recognition
experts in order to teach on these subjects,”
“testified approximately ten times in York County about field
sobriety testing,”
“looked over the validation studies for standardized field
sobriety tests,” and
“written about the reliability and the neurological issues
involved with those tests.”
Trial Court Opinion, 12/17/18, at 7-8.
-9-
J-S22045-19
The Commonwealth did not dispute any of these qualifications. Clearly,
Dr. Guzzardi had a reasonable pretension to knowledge about whether
sobriety tests have been scientifically validated to detect drug impairment.
This was within the course of “knowledge, intelligence, and experience,” even
if he had not personally administered sobriety exercises as a police offer would
in the field. The Commonwealth could have challenged the weight of Dr.
Guzzardi’s testimony based on any relevant limits of his expertise, but there
was no basis for the opinion to be completely excluded. The trier of fact should
have been permitted to weigh the expert’s opinion against the
Commonwealth’s evidence of Taylor’s guilt.
III.
Since the trial court erred in precluding the testimony regarding the
extent to which sobriety tests may reliably be used to detect drug impairment,
it is necessary to determine whether the error now warrants relief. In this
analysis, the order on review must be vacated to correct the error unless we
are “convinced beyond a reasonable doubt that the error is harmless.”
Commonwealth v. Story, 383 A.2d 155, 162 (Pa. 1978). Error may only be
considered harmless where:
(1) the error did not prejudice the defendant or the prejudice was
de minimis; or (2) the erroneously admitted evidence was merely
cumulative of other, untainted evidence which was substantially
similar to the erroneously admitted evidence; or (3) the properly
admitted and uncontradicted evidence of guilt was so
overwhelming and the prejudicial effect of the error was so
insignificant by comparison that the error could not have
contributed to the verdict.

Commonwealth v. Williams, 573 A.2d 536, 538–39 (1990) (citing Story,
383 A.2d at 162). “Harmless error exists where the appellate court is
convinced beyond a reasonable doubt that the erroneously admitted evidence
could not have contributed to the verdict. If there is a reasonable probability
that an error may have contributed to the verdict, the error is not harmless.”
Commonwealth v. Brennan, 696 A.2d 1201, 1203 (Pa. Super. 1997)
(internal citations omitted).
The exclusion of Dr. Guzzardi’s testimony was not harmless beyond a
reasonable doubt. At trial, the Commonwealth sought to prove that Taylor
was impaired by drugs at the time she crashed her vehicle. No blood test
result was admitted into evidence, so the jury had to determine whether
Taylor was impaired by drugs based solely on her conduct. The
Commonwealth’s key witness was the arresting officer who testified that he
could detect Taylor’s alleged drug impairment from her poor performance on
field sobriety tests. The officer’s opinion ruled out Taylor’s only theory of
innocence – that she performed badly not because of drug use, but due to
head injuries sustained in the accident.
The source of Taylor’s impairment was the question for the jury to
decide at trial. If the jury accepted the officer’s opinion on Taylor’s drug use,
it could have found that she committed the offense of DUI, of which
- 11 -
J-S22045-19
impairment is a necessary element.4 Further, although impairment is not an
element of child endangerment, the jury could have relied on evidence of
Taylor’s alleged impairment to conclude that by knowingly taking drugs, she
placed her child in harm’s way, in violation of her duty of care.5
Dr. Guzzardi would have opined that field sobriety tests are not
scientifically proven methods of detecting drug impairment. If admitted into
evidence and accepted by the jury, this expert opinion would have rebutted
the officer’s conclusion that Taylor was impaired by drugs. It was for the jury
to weigh that evidence, but it never got the chance. See Commonwealth v.
Sanchez, 82 A.3d 943, 972 (Pa. 2013) (“[I]t is the fact-finder’s province to
weigh the evidence, determine the credibility of witnesses, and believe all,
part, or none of the evidence submitted.”). As a result of the trial court’s

(d) Controlled substances.--An individual may not drive,
operate or be in actual physical control of the movement of a
vehicle under any of the following circumstances:
(2) The individual is under the influence of a drug or
combination of drugs to a degree which impairs the

of the child by violating a duty of care, protection or support.” 18 Pa.C.S. §
4304(a)(1).

J-S22045-19
error, the arresting officer’s opinion about Taylor’s drug impairment was
unchallenged.
Under the circumstances of this case, the excluded testimony went to
the heart of a central jury question. The error in excluding Dr. Guzzardi’s
testimony therefore resulted in more than de minimus prejudice, and the
excluded testimony was not cumulative. The trial court’s error was not
harmless beyond a reasonable doubt and, as a result, the judgment of
sentence cannot stand.
Judgment of sentence vacated. Case remanded for a new trial on the
counts of driving under the influence and endangering the welfare of a child.
Jurisdiction relinquished.
Judgment Entered.
