KARL FREDERICK SCHULTZ, Appellant
V.
THE STATE OF TEXAS, Appellee
On Appeal from County Criminal Court at Law No. 1
Harris County, Texas
Trial Court Case No. 1802555
OPINION
Appellant, Karl Frederick Schultz, was charged by indictment with driving
while intoxicated. 1 Appellant moved to suppress the results of his breath test, and
the trial court denied the motion. Appellant then pleaded guilty to the offense,
1
See TEX. PENAL CODE ANN. § 49.04(a) (Vernon 2014).
subject to his right to appeal the ruling on the motion to suppress. The trial court
found appellant guilty and assessed punishment at confinement for one year. The
trial court then suspended the sentence and placed Appellant on community
supervision. On appeal, Appellant argues in three issues that (1) the trial court
abused its discretion by excluding certain evidence from the suppression hearing,
(2) the breath test results should have been suppressed because they were obtained
in violation of the law, and (3) the breath test results should have been suppressed
because they were not reliable.
We affirm.
Background
Appellant was arrested in the early morning hours of January 7, 2012 for
driving while intoxicated. Appellant stipulated at the suppression hearing that
reasonable suspicion existed for a detention, that probable cause justified his arrest,
and that the required statutory warnings were properly given to him. The arresting
officers took Appellant to a nearby gas station. Parked at the gas station was a
Houston Police Department Breath Alcohol Testing van. Appellant agreed to give
a breath test.
Officer D. Ciers testified at the suppression hearing. He testified that he
brought appellant into the van and closed the door. It was a cool morning—about
72 degrees Fahrenheit inside the van—and the air conditioner was not running in
2
the van. Officer Ciers observed Appellant for a 15-minute period and then
conducted the breath test using a machine mounted inside the van called the
Intoxilyzer 5000.
Ronald Oliver, a technical supervisor for the Texas Department of Public
Safety, also testified at the suppression hearing. Part of Oliver’s responsibilities as
a technical supervisor was to regularly inspect and calibrate the breath test
machines. Oliver testified that the breath test machine used on Appellant was
inspected about one week before Appellant’s test. He also testified that
Appellant’s test was the first one after the inspection. When questioned about
whether the inspections on the machines were valid when the machines were used
in a mobile van, Oliver testified,
A testing site is a testing site. Whether it has wheels or not doesn’t
make any difference. If the testing site is appropriate, then you can get
good, valid alcohol results from that instrument. If it’s in a bad
location, whether it have wheels or not have wheels; that we have
testing sites in jails that overheat and there are times when we can’t
run tests, then that physical location is it’s just too hot or too cold.
Oliver also testified about the approval of the Houston Police Department’s
breath testing program by the Texas Department of Public Safety’s scientific
director. Specifically, Oliver testified,
Q. And is [the Intoxilyzer 5000 that was used on Appellant]
certified by the scientific director of the Texas Department of
Public Safety?
A. Yes.
3
Q. And was it certified on the date of January 7th, 2012?
A. That is correct.
Q. And is that instrument used as a part of the breath test program?
A. That is correct.
Q. Are you responsible for the maintenance of that instrument?
A. I was, yes.
Finally, Oliver testified at trial about the Intoxilyzer 5000’s many failsafes
for inaccurate breath tests. The machine tests for the presence of alcohol,
specifically ethanol. Ethanol absorbs a specific wavelength of infrared light.
When that wavelength of light is passed through the air chamber, less of the light
will come out the other side of the chamber due to its absorption by the ethanol. A
measure of the decrease in the amount of the infrared light establishes the amount
of ethanol present in the sample.
Other known chemicals can also absorb infrared light at the same
wavelength. These are called interferents and can potentially cause a false
identification of ethanol. To account for this, the machine also tests for five known
interferents, such as acetone. If any interferents are detected, the machine subtracts
the amount of interferents detected from the total amount detected for the test
wavelength.
4
Every time the machine is run, it performs a test of its internal components
to ensure that the circuitry is functioning properly. If it is not functioning properly,
the test ends and the report explains an error occurred.
Next, it purges the system of the air in it at the time, drawing in air from its
current environment. The machine then tests that air sample. The test subject then
breathes into a tube connected to the machine. The machine tests that breath
sample as well. It then performs another test from the current environment. After
that, the machine then tests what is known as a reference sample. The reference
sample is designed to produce a result for a specific volume of alcohol. The test
subject then breathes again in the tube, and the machine tests that sample as well.
Another sample of the air in the current environment is tested. Finally, the
machine draws another sample in from the environment and tests it again.
After the tests are complete, the machine prints out a report showing the
results for each test. If any errors occur during the testing, the report explains an
error occurred and does not include the testing results. Potential errors include
improperly functioning circuitry, overheating, being overly cold, interferents being
detected in the ambient air samples, and the two breath samples from the test
subject being too far apart.
In the present case, the report did not identify any errors. It identified the
alcohol concentration for the first air sample at 0.000. It identified the alcohol
5
concentration for Appellant’s first breath sample at 0.158.2 It identified the alcohol
concentration for the second air sample at 0.000. The reference sample was
predicted to identify an alcohol concentration of 0.080. The machine identified the
alcohol concentration for the reference sample at 0.077. It identified the alcohol
concentration for the third air sample at 0.000. It identified the alcohol
concentration for Appellant’s second breath sample at 0.168. Finally, it identified
the alcohol concentration for the fourth air sample at 0.000.
Appellant presented the expert testimony of Raymond McMains. McMains
had been a technical supervisor for the Texas Department of Public Safety for 17
years. McMains testified that he was aware of some tests where ethanol and
acetone were tested in a sample together. “And a few times it did not detect that.
And in one case it didn’t subtract it because they used a .08 solution and it showed
up a .09.” McMains also testified that, based on his study of breath tests conducted
throughout the state from 2007 to 2011, “the Houston [breath alcohol testing] vans
were nine times more likely to detect an interferent than a nonmobile Intoxilyzer
site.”
After all the witnesses had testified, Appellant offered into evidence a
marketing brochure from the company that makes the Intoxilyzer 5000. The
2
Breath tests in Texas are a measurement of grams of alcohol per 210 liters of
breath. TEX. PENAL CODE ANN. § 49.01(1)(A) (Vernon 2011).
6
brochure was for a machine called the Intoxilyzer 8000. There was no sponsoring
witness.
Admission of Evidence
In his second issue, Appellant argues the trial court abused its discretion by
excluding a marketing brochure for another machine made by the company that
makes the Intoxilyzer 5000.
A. Standard of Review & Applicable Law
With the exception of rules concerning privileges, the Texas Rules of
Evidence do not apply in a suppression hearing. TEX. R. EVID. 101(d)(1)(A),
104(a); Granados v. State, 85 S.W.3d 217, 227 (Tex. Crim. App. 2002). Instead,
“[t]he trial judge makes a legal ruling to admit or exclude evidence based upon the
relevance and reliability of the factual information submitted by the parties.” Ford
v. State, 305 S.W.3d 530, 535 (Tex. Crim. App. 2009). We afford “great
deference” to the trial court’s decision to admit or exclude evidence in a hearing on
a motion to suppress, and we will overturn that decision on appeal only when “a
flagrant abuse of discretion is shown.” Delao v. State, 235 S.W.3d 235, 238 (Tex.
Crim. App. 2007).
B. Analysis
After all the witnesses had testified, Appellant offered into evidence two
marketing brochures from the company that makes the Intoxilyzer 5000. The first
7
brochure was for the Intoxilyzer 5000. The second brochure was for a machine
called the Intoxilyzer 8000. The Intoxilizer 8000 brochure states that it is “fully
mobile.” The Intoxilizer 5000 brochure does not address its ability to be used in
mobile environments.
The State had no objection to the brochure for the Intoxilizer 5000, but
objected that the brochure for the Intoxilizer 8000 was not relevant. The trial court
agreed and sustained the objection for the Intoxilizer 8000 brochure.
Even assuming the trial court’s exclusion of the Intoxilizer 8000 brochure
was error, Appellant must establish that the error was harmful. Appellant’s
argument for harm is contained in one sentence. “Had the trial judge considered
the content of the brochures as evidence of the manufacturer’s purpose and design
of the different Intoxilizers, her ruling may have been different.”
Even when the rules of evidence do apply, we evaluate harm in the
admission or exclusion of evidence for non-constitutional error. Ray v. State, 178
S.W.3d 833, 836 (Tex. Crim. App. 2005). For non-constitutional errors, we
disregard errors that do not affect the appellant’s substantial rights. TEX. R. APP. P.
44.2(b); Robinson v. State, 236 S.W.3d 260, 269 (Tex. App.—Houston [1st Dist.]
2007, pet. ref’d). An error affects a substantial right only when the error had a
substantial and injurious effect or influence on the jury’s verdict. Robinson, 236
S.W.3d at 269 (citing King v. State, 953 S.W.2d 266, 271 (Tex. Crim. App. 1997)).
8
In contrast, “if we are fairly assured that the error did not influence the jury or had
but a slight effect, we conclude that the error was harmless.” Ray, 178 S.W.3d at
836.
The only relevance that can be attributed to the Intoxilizer 8000 brochure is
to show that the machine has been advertised as “fully mobile.” The Intoxilizer
5000 brochure is silent on this issue. At best, this creates a weak inference that,
because the Intoxilizer 5000 brochure did not advertise that the machine was fully
mobile, the machine may not have been intended to be used in mobile
environments. Accordingly, we are fairly assured that the excluded brochure, if
admitted, would only have had a slight effect on the trial court’s decision.
We overrule Appellant’s second issue.
Motion to Suppress
In his first issue, Appellant argues the trial court abused its discretion by
denying the motion to suppress because the breath test was performed in violation
of article 38.23 of the Texas Code of Criminal Procedure. See TEX. CODE CRIM.
PROC. ANN. art. 38.23(a) (Vernon 2005). In his third issue, Appellant argues the
trial court abused its discretion by denying the motion to suppress because the
breath test was not reliable pursuant to rules 702 and 705 of the Texas Rules of
Evidence. See TEX. R. EVID. 702, 705(c).
9
A. Standard of Review
We review a trial court’s denial of a motion to suppress under a bifurcated
standard of review. Turrubiate v. State, 399 S.W.3d 147, 150 (Tex. Crim. App.
2013). We review the trial court’s factual findings for abuse of discretion and
review the trial court’s application of the law to the facts de novo. Id. Almost total
deference should be given to a trial court’s determination of historical facts,
especially those based on an evaluation of witness credibility or demeanor.
Gonzales v. State, 369 S.W.3d 851, 854 (Tex. Crim. App. 2012). At a suppression
hearing, the trial court is the sole and exclusive trier of fact and judge of the
witnesses’ credibility and may choose to believe or disbelieve all or any part of the
witnesses’ testimony. Maxwell v. State, 73 S.W.3d 278, 281 (Tex. Crim. App.
2002); State v. Ross, 32 S.W.3d 853, 855 (Tex. Crim. App. 2000). “If the trial
judge makes express findings of fact, we view the evidence in the light most
favorable to his ruling and determine whether the evidence supports these factual
findings.” Valtierra v. State, 310 S.W.3d 442, 447 (Tex. Crim. App. 2010). We
will defer to the trial court’s fact findings and not disturb the findings on appeal
unless the trial court abused its discretion in making a finding not supported by the
record. Cantu v. State, 817 S.W.2d 74, 77 (Tex. Crim. App. 1991).
10
B. Legality of Breath Test
In his first issue, Appellant argues the trial court abused its discretion by
denying the motion to suppress because the breath test was performed in violation
of article 38.23 of the Texas Code of Criminal Procedure. See TEX. CODE CRIM.
PROC. ANN. art. 38.23(a). Appellant’s essential argument is that the Texas
Department of Public Safety’s Standard Operating Guidelines for the breath test
machines does not permit the Intoxilyzer 5000s to be used in a mobile location
without an inspection at each new location. Accordingly, Appellant argues,
because the Intoxilyzer 5000 had not been inspected upon being moved to the
location where Appellant was tested, the breath test was performed in violation of
the law and must be suppressed.
The State argues that, to determine whether a breath test was performed in
compliance with the law, courts cannot look beyond the relevant statutes and
regulations. Because the Texas Department of Public Safety’s Standard Operating
Guidelines are neither statutes nor regulations, the State argues, the Standard
Operating Guidelines cannot be a basis for suppressing the breath test.
Article 38.23 of the Texas Code of Criminal Procedure provides,
No evidence obtained by an officer or other person in violation of any
provisions of the Constitution or laws of the State of Texas, or of the
Constitution or laws of the United States of America, shall be
admitted in evidence against the accused on the trial of any criminal
case.
11
Id. Typically, “noncompliance with administrative agency rules does not provide a
basis for the exclusion of evidence under article 38.23.” Atkinson v. State, 923
S.W.2d 21, 23 n.1 (Tex. Crim. App. 1996), abrogated on other grounds by Motilla
v. State, 78 S.W.3d 352 (Tex. Crim. App. 2002). When a statute specifically
makes evidence inadmissible when it has been obtained in violation of agency
regulations, however, the regulations become a part of the analysis. See id.
In Atkinson, the Court of Criminal Appeals held that the then-applicable
version of a statute incorporated review of the applicable regulations into the
determination of whether there was a violation of article 38.23. See id. at 23 & n.1.
The State argues that a change in the text of the statute establishes that the
regulations do not need to be considered any more.
The statute in effect under Atkinson provided, in pertinent part, “Analysis of
a specimen of the person’s breath, to be considered valid under the provisions of
this section, must be performed according to rules of the Texas Department of
Public Safety . . . .” Act of May 27, 1983, 68th Leg., R.S., ch. 303, § 3, 1983 Tex.
Gen. Laws 1568, 1576–77, repealed by Act of May 29, 1993, 73rd Leg., R.S.,
ch. 900, § 1.15, 1993 Tex. Gen. Laws 3586, 3704 (formerly TEX. REV. CIV. STAT.
ANN. art. 6701l–5, § 3(a)).
The State correctly points out that the phrase “to be considered valid” does
not appear in the current version of the statute. See TEX. TRANSP. CODE ANN.
12
§ 724.016(a) (Vernon 2011). Instead, the current version of the statute provides, in
pertinent part, “A breath specimen taken at the request or order of a peace officer
must be taken and analyzed under rules of the department.” Id. The State argues
that the removal of the phrase “to be considered valid” indicates an intention on the
part of the Texas Legislature to remove the administrative regulations as part of the
review for compliance with the law under article 38.23. We must disagree.
Former article 6701l–5 was repealed and current section 724.016 was
enacted due to the creation of the Transportation Code. See TEX. TRANSP. CODE
ANN. § 1.001 (Vernon 2011). The Revisor’s Note to section 724.016 explains,
Section 3(b), V.A.C.S. Article 6701l-5, provides that analysis of a
specimen of a person’s breath, “to be considered valid under the
provisions of this section,” must be performed according to rules of
the Department of Public Safety by an individual possessing a
certificate issued by the department. The revised law omits the quoted
language as unnecessary because it is implemented by the use of the
word “must.”
Id. § 724.016 revisor’s note; see also TEX. TRANSP. CODE ANN. vol. 1, preface, p.
III (Vernon 2011) (“The proposed Transportation Code, as submitted to the Texas
Legislature by the Legislative Council, contained Revisor’s Notes under various
sections. These Notes . . . were not included in the Code as enacted, but are
supplied under selected sections in this edition as an aid to research and
interpretation.”). Additionally, the creation of the Transportation Code was
intended to consolidate the relevant statutes for a topic within a code “without
13
substantive change.” TEX. TRANSP. CODE ANN. § 1.001(a). Because the creation
of the Transportation Code was not intended to make substantive changes to the
statutes and because the phrase “to be considered valid under the provisions of this
section” was removed because it was considered redundant, we hold Atkinson still
applies, and we must still look to the administrative code to determine whether
there has been a violation of the law.
The question becomes, then, whether the relevant regulations further
incorporate the Texas Department of Public Safety’s Standard Operating
Guidelines into the determination of whether the law has been violated as
Appellant argues. Appellant correctly argues that all Texas agencies must perform
their breath tests under an approved breath test program. See 37 TEX. ADMIN.
CODE § 19.4(a), (b)(3), (f)(6). Appellant argues that we must then consider the
program’s operating guidelines to determine whether the law has been violated.
We disagree.
As we note above, typically, “noncompliance with administrative agency
rules does not provide a basis for the exclusion of evidence under article 38.23.”
Atkinson, 923 S.W.2d at 23 n.1. The Court of Criminal Appeals held in Atkinson,
however, that the statutory requirement that “‘[a]nalysis of a specimen of the
person’s breath, to be considered valid . . . , must be performed according to rules
of the Texas Department of Public Safety . . . .’” created an exception to the typical
14
analysis and compelled consideration of the regulations. Id. at 23 & n.1 (quoting
then-applicable predecessor to section 724.016 of Texas Transportation Code).
The requirement that the test be performed according to the regulations drew the
regulations into consideration. See id.
The corollary language in the Texas Department of Public Safety’s
regulations provides, “All breath alcohol testing techniques, methods and programs
to be used for evidential purposes must have the approval of the scientific
director.” 37 TEX. ADMIN. CODE § 19.4(a). What is compelled here, as opposed to
what was compelled in Atkinson, is approval of the scientific director, not
performance according to the rules set forth in the standard operating guidelines.
Id. As long as the regulations have been complied with—including obtaining
approval of the scientific director—then article 38.23 has been satisfied. See id.;
Atkinson, 923 S.W.2d at 23 & n.1.
The “scientific director” is “[t]he individual or his designee responsible for
the implementation, administration and enforcement of the Texas breath alcohol
testing regulations.” 37 TEX. ADMIN. CODE § 19.1(20). This is the scientific
director for the Texas Department of Public Safety. The testimony at the hearing
concerning approval is as follows:
Q. And is [the Intoxilyzer 5000 used on Appellant] certified by the
scientific director of the Texas Department of Public Safety?
A. Yes.
15
Q. And was it certified on the date of January 7th, 2012?
A. That is correct.
Q. And is that instrument used as a part of the breath test program?
A. That is correct.
Q. Are you responsible for the maintenance of that instrument?
A. I was, yes.
While not the most direct way of establishing approval of the program by the
scientific director, the trial court could have reasonably inferred that the scientific
director would not certify a machine for use in a program that had not been
approved. 3
Appellant also relies on subsection (f) of section 19.4 of the Texas
Department of Public Safety’s regulations to argue that the guidelines are
incorporated into the 38.23 analysis. 37 TEX. ADMIN. CODE § 19.4(f). Subsection
(f) provides,
Approval of any breath alcohol testing program is contingent upon the
applying agency or laboratory’s agreement to conform and abide by
any directives, orders, or policies issued or to be issued by the
scientific director regarding any aspect of the breath alcohol testing
program; this shall include, but not be limited to, the following . . . .
3
Moreover, this testimony came from Ronald Oliver, a technical supervisor from
the Texas Department of Public Safety. “Technical supervisors, when required,
shall provide expert testimony . . . concerning the approval of techniques, methods
and programs under their supervision.” 37 TEX. ADMIN. CODE § 19.4(h). The
trial court could have further reasonably concluded that Oliver would not have
testified about the validity of a program that had not been approved.
16
Id. This subsection concerns an applying agency’s necessary agreements in order
to have their program approved by the scientific director. This does not
specifically incorporate any of those agreements into the 38.23 analysis.
Regulations commonly have requirements in addition to those specifically
mandated under the law. But those regulations are commonly left out of the 38.23
analysis. See Atkinson, 923 S.W.2d at 23 n.1; see also Garza v. State, 126 S.W.3d
79, 85–86 (Tex. Crim. App. 2004) (rejecting reliance on regulation to establish
violation of 38.23 because no statute declaring violation of agency rule was
violation of law). Accordingly, the mere fact that the agency regulations provide
requirements for approval does not establish that the regulations intended to make
violations of the agreements constitute violations of law.
We hold that there is evidence in the record that the breath test was obtained
in compliance with the law for purposes of article 38.23 of the Texas Code of
Criminal Procedure. We overrule appellant’s first issue.
C. Reliability of Breath Test
In his third issue, Appellant argues the trial court abused its discretion by
denying the motion to suppress because the breath test was not reliable pursuant to
rules 702 and 705 of the Texas Rules of Evidence. See TEX. R. EVID. 702, 705(c).
As in his first issue, Appellant’s essential argument is that the Texas Department of
Public Safety’s Standard Operating Guidelines for the breath test machines does
17
not permit the Intoxilyzer 5000’s to be used in a mobile location without an
inspection at each new location. Because the Intoxilyzer 5000 had not been
inspected once it was at the location where Appellant was tested, Appellant argues,
the results lack scientific reliability and, accordingly, must be suppressed.
When a defendant challenges the reliability of scientific evidence in a
motion to suppress, the State bears the burden at the hearing to establish reliability.
State v. Esparza, 413 S.W.3d 81, 86 (Tex. Crim. App. 2013). Rule 702 of the
Texas Rules of Evidence provides, “If scientific, technical, or other specialized
knowledge will assist the trier of fact to understand the evidence or to determine a
fact in issue, a witness qualified as an expert by knowledge, skill, experience,
training, or education, may testify thereto in the form of an opinion or otherwise.”
TEX. R. EVID. 702. Typically, in order for scientific evidence “to be considered
sufficiently reliable as to be of help to a jury,” the evidence must satisfy three
criteria: “(1) the underlying scientific theory must be valid; (2) the technique
applying the theory must be valid; and (3) the technique must have been properly
applied on the occasion in question.” Reynolds v. State, 204 S.W.3d 386, 390
(Tex. Crim. App. 2006) (citing Kelly v. State, 824 S.W.2d 568, 573 (Tex. Crim.
App. 1992)).
In the context of breath test evidence, however, the analysis is modified.
“[T]he Legislature has already determined that the underlying science is valid, and
18
that the technique applying it is valid as long as it is administered by individuals
certified by, and using methods approved by the rules of, DPS.” Id. (citing TEX.
TRANSP. CODE ANN. § 724.064 (Vernon 2011)). The only determination for a trial
court to make in what is called a Kelly hearing, then, is “whether the technique was
properly applied in accordance with the rules of DPS on the particular occasion in
question.” Id. at 391.
It is in the context of determining whether scientific results were obtained
“using methods approved by the rules of DPS” that we agree with Appellant that
the determination of whether the standard operating guidelines were followed
becomes relevant.4 In order to make this determination, however, certain evidence
presented at the hearing must first be established.
A police officer conducting the breath test does not need to “be able to
articulate the scientific principle behind the apparatus or the technology
implementing it.” Id. Instead, the officer must be supervised by a technical
supervisor that understands the underlying scientific principles. That technical
4
Even if we held that the guidelines were not followed, we would still have to
analyze (1) whether any deviation from the guidelines results in a per se
determination of unreliability and (2), if not, whether the particular deviation
required a determination of unreliability. As the State points out, the Standard
Operating Guidelines covers a broad range of matters, including record keeping
and electronic data management. In essence, the State is arguing that requiring a
per se rule would result in a back-door 38.23 analysis for the standard operating
guidelines. Because we hold that the guidelines were followed, however, we do
not need to reach this issue.
19
supervisor must also perform periodic tests on the instruments used by the police
officers. According to the Standard Operating Guidelines for Technical
Supervisors in effect at the time of Appellant’s breath test, 5 the technical
supervisor must perform two types of periodic tests on the instruments: inspections
and calibration. A calibration is a test of known alcohol concentrations to ensure
that the machine is correctly identifying the amount of alcohol in its tests. In
contrast, an inspection involves (1) ensuring that the machine detects and subtracts
the effect of acetone and (2) conducting a breath test in the normal testing mode.
Appellant’s complaint focuses on the inspection of the machine that he used.
The relevant standard operating guidelines were admitted into evidence.
They provide,
1.1 An official inspection by a Technical Supervisor can only be
conducted at the evidential testing location. Each part of the
inspection shall occur at the testing location and includes not
only the instrument, but the associated equipment and the
testing environment as a whole.
1.1.1 The capability of the instrument to detect and subtract the
effect of acetone shall be tested.
....
1.1.2 A Technical Supervisor shall conduct a breath test in the
normal subject testing mode used for evidential
testing. . . .
5
Appellant offered into evidence only the first page of the Standard Operating
Guidelines for Technical Supervisors in effect at the time. Nevertheless, Oliver
testified as to his responsibilities as a technical supervisor.
20
1.1.3 A Technical Supervisor may conduct additional tests or
checks of the instrument and simulator as he/she deems
necessary.
1.2 A complete inspection (1.1) shall be performed by a Technical
Supervisor each time an instrument is placed into or returned to
service at a testing location.
Appellant’s argument focuses on the phrase “testing location” as used in
these guidelines. It is undisputed that “testing location” is not defined as it applies
to the standard operating guidelines. Appellant argues that “testing location”
should be interpreted to mean a fixed, physical location. Based on that
interpretation, Appellant argues that the breath testing machines are incompatible
with use in a mobile van unless the instrument is inspected each time it moves to a
new location.
In contrast, Oliver testified that, for purposes of the breath alcohol testing
vans, “testing location” meant the van itself, regardless of the fixed, physical
location that the van is in at any given time. He testified,
A testing site is a testing site. Whether it has wheels or not doesn’t
make any difference. If the testing site is appropriate, then you can get
good, valid alcohol results from that instrument. If it’s in a bad
location, whether it have wheels or not have wheels; that we have
testing sites in jails that overheat and there are times when we can’t
run tests, then that physical location is it’s just too hot or too cold.
Oliver testified that the inspection for the instrument in question was
performed about one week before Appellant’s breath test and that Appellant’s test
was the first test performed after the inspection.
21
We agree that “testing location” is not defined as it applies to the standard
operating guidelines. We also agree with Appellant that undefined terms like this
are typically given their ordinary meaning. Watson v. State, 369 S.W.3d 865, 870
(Tex. Crim. App. 2012). We disagree, however, that anything in the guidelines
compels the interpretation that the location must be a fixed location.6 Oliver
testified as the representative for the Department of Public Service. The
Department of Public Service is the agency tasked with “adopt[ing] rules

§ 724.016(b)(1). Accordingly, the representative of the agency that drafted the
standard operating guidelines pursuant to its legislative authority testified that
“testing location” meant the van itself and not the fixed physical location the van
might be in at any given time. We hold this interpretation is reasonable and a
different interpretation is not compelled.
Appellant argues that the requirement that the inspection includes “the
testing environment as a whole” and that such an inspection cannot be conducted
when the testing machine is mobile. Oliver acknowledged that inspection includes

In civil cases, “[i]f there is vagueness, ambiguity, or room for policy
determinations in a statute or regulation . . . we normally defer to the agency’s
interpretation unless it is plainly erroneous or inconsistent with the language of the
statute, regulation, or rule.” TGS-NOPEC Geophysical Co. v. Combs, 340 S.W.3d

cases.

the testing environment as a whole, but also testified that whether a site is mobile
is not relevant to the inspection process.7 The trial court agreed with Oliver, and
we find no reason to overturn this. Accordingly, we hold the State carried its
burden of establishing that “the technique was properly applied in accordance with
the rules of DPS on the particular occasion in question.” Reynolds, 204 S.W.3d at
391; see also Esparza, 413 S.W.3d at 86 (holding State carries initial burden of
establishing reliability of scientific evidence).
Once the State carried its initial burden, the burden then shifted to Appellant
to establish that the evidence was otherwise unreliable. See Pham v. State, 175
S.W.3d 767, 773 (Tex. Crim. App. 2005) (holding ultimate burden of persuasion is
on movant in motion to suppress hearing). Appellant argued that the breath test
was unreliable because the machine was not in the location where it was inspected
and, accordingly, there was no assurance that the machine was properly detecting
what are known as interferents. Further, appellant points out that the van was at a
gas station, which could contain a large number of unknown interferents in the air.
Oliver testified at trial about the Intoxilyzer 5000’s many failsafes for
inaccurate breath tests. The machine tests for the presence of alcohol, specifically
7
Appellant points out that Oliver also testified that, if he moved a breath test
machine assigned to a fixed, physical location, he would perform another
inspection of the instrument, even if the machine was moved to a new location in
the same room. There was no testimony, however, that the additional inspection
was a requirement of the standard operating guidelines.

ethanol. Ethanol absorbs a specific wavelength of infrared light. When that
wavelength of light is passed through the air chamber, less of the light will come
out the other side of the chamber due to its absorption by the ethanol. A measure
of the decrease in the amount of the infrared light establishes the amount of ethanol
present in the sample.
Other known chemicals can also absorb infrared light at the same
wavelength. These are called interferents and can potentially cause a false
identification of ethanol. To account for this, the machine also tests for five known
interferents, such as acetone. If any interferents are detected, the machine subtracts
the amount of interferents detected from the total amount detected for the test
wavelength.
Every time the machine is run, it performs a test of its internal components
to ensure that the circuitry is functioning properly. If it is not functioning properly,
the test ends and the report explains an error occurred.
Next, it purges the system of the air in it at the time, drawing in air from its
current environment. The machine then tests that air sample. The test subject then
breathes into a tube connected to the machine. It then performs another test from
the current environment. After that, the machine then tests what is known as a
reference sample. The reference sample is designed to produce a result for a
specific volume of alcohol. The test subject then breathes again in the tube, and
24
the machine tests that sample as well. Another sample of the air in the current
environment is tested. Finally, the machine draws another sample in from the
environment and tests it again.
After the tests are complete, the machine prints out a report showing the
results for each test. If any errors occur during the testing, the report explains an
error occurred and does not include the testing results. Potential errors include
improperly functioning circuitry, overheating, being overly cold, interferents being
detected in the ambient air samples, and the two breath samples from the test
subject being too far apart.
In the present case, the report did not identify any errors. It identified the
alcohol concentration for the first air sample at 0.000. It identified the alcohol
concentration for Appellant’s first breath sample at 0.158. It identified the alcohol
concentration for the second air sample at 0.000. The reference sample was
predicted to identify an alcohol concentration of 0.080. The machine identified the
alcohol concentration for the reference sample at 0.077. It identified the alcohol
concentration for the third air sample at 0.000. It identified the alcohol
concentration for Appellant’s second breath sample at 0.168. Finally, it identified
the alcohol concentration for the fourth air sample at 0.000.
It is important to point out that Appellant did not establish proof of any
interferents for which the machine did not already test. In other words, Appellant
25
did not identify any chemical compounds that would absorb the test infrared
wavelength that the machine could not already detect. To the contrary, the air
samples from the environment both tested as having an alcohol concentration of
0.000. Appellant argues in his brief that there are a large number of compounds
present in the air at a gas station that could create a false positive. Similarly,
Appellant hypothesizes that there could be compounds that would not be detected
in the air but might create false positives when metabolized and exhaled in human
breath. This is pure speculation, however, and does nothing to advance
Appellant’s burden of persuasion or to show how the trial court abused its
discretion. See Hooper v. State, 214 S.W.3d 9, 16 (Tex. Crim. App. 2007)
(holding speculation is insufficient to carry burden).
The most substantive proof of failure to detect interferents came from the
testimony of Appellant’s expert, McMains. McMains testified that he was aware
of some tests where ethanol and acetone were tested in a sample together. “And a
few times it did not detect that. And in one case it didn’t subtract it because they
used a .08 solution and it showed up a .09.” Based on this testimony, the greatest
potential variance that has been established is a difference of 0.01 when ethanol
and acetone were present together. Appellant’s breath tests, however, were 0.158
and 0.168. The legal limit in Texas is 0.08 grams of alcohol per 210 liters of
breath. See TEX. PENAL CODE ANN. §§ 49.01(1)(A), (2), 49.04(a) (Vernon 2011).
26
Even if the trial court found this testimony credible and credited it, adjusting the
variance in the combined presence of alcohol and acetone, Appellant’s lowest
breath test was still 0.068 grams of alcohol per 210 liters of breath over the legal
limit. We hold the trial court could have reasonably determined that, in
Appellant’s circumstances, a potential 0.01 variance did not render his breath test
unreliable.
McMains also testified that, based on his study of breath tests conducted
throughout the state from 2007 to 2011, “the Houston [breath alcohol testing] vans
were nine times more likely to detect an interferent than a nonmobile Intoxilyzer
site.” Even assuming the trial court found this testimony credible and credited it,
McMains’s testimony concerns the machines’ successful detection of interferents.
Given the uncontradicted testimony that the machines would report an error when
it detected interferents in the ambient air and would exclude the effects of
interferents when present in breath samples, Appellant has failed to establish how
such detections would cause the test results to be unreliable.
We hold the State carried its burden of establishing that the breath tests were
reliable. We hold Appellant failed to carry his burden, after the burden shifted to
him, that the tests were unreliable. Accordingly, we overrule Appellant’s third
issue.
