SYLLABUS OF THE COURT
The results of a speed-measuring device using either radar or laser technology are
admissible in court without expert testimony establishing, or the court
taking judicial notice of, the reliability of the scientific principles of that
technology. However, the factfinder is required to determine whether the
evidence presented concerning the accuracy of the particular speed-
measuring device and the qualifications of the person who used it is
sufficient to support a conviction based on the device’s results. (E.
Cleveland v. Ferell, 168 Ohio St. 298, 154 N.E.2d 630 (1958), approved
and followed.)

STEWART, J.
{¶ 1} In this certified-conflict case following a judgment of the Eighth
District Court of Appeals, we consider whether the results of a speed-measuring
device using either radar or laser technology are admissible in court without expert
testimony establishing, or the court taking judicial notice of, the reliability of the
scientific principles underlying that technology. We answer that question in the
affirmative, but we hold that the factfinder is required to determine whether the
evidence presented concerning the accuracy of the particular speed-measuring
device used and the qualifications of the person who used it is sufficient to support
a conviction based on the device’s results.
Facts and Procedural History
{¶ 2} On May 17, 2017, a city of Brook Park police officer issued appellant,
Joseph G. Rodojev, a traffic citation for driving his vehicle 15 miles per hour over
the posted speed limit in violation of Brook Park Code of Ordinances 333.03. The
officer calculated Rodojev’s speed using the LTI 20/20 TruSpeed S laser speed-
detection device. Rodojev pleaded not guilty in the Brook Park Mayor’s Court and
2
January Term, 2020
his case was transferred to the Berea Municipal Court.1 During Rodojev’s bench
trial, the trial court admitted into evidence and considered the results of the laser
speed-measuring device without expert testimony establishing the reliability of the
scientific principles underlying the device’s technology. The trial court did not
specifically take judicial notice of the device’s reliability. The court convicted
Rodojev of the charged offense.
{¶ 3} Rodojev appealed his conviction to the Eighth District Court of
Appeals and raised an assignment of error challenging the trial court’s admission
of the results of the laser speed-measuring device without expert testimony
establishing the scientific reliability of the technology.
{¶ 4} After reviewing Rodojev’s argument under the plain-error standard of
review because Rodojev did not make an objection in the trial court based on the
reliability of the device, the Eighth District affirmed Rodojev’s conviction. 2018-
Ohio-5028, ¶ 1, 10, 25. Citing this court’s decision in E. Cleveland v. Ferell, 168
Ohio St. 298, 154 N.E.2d 630 (1958), the Eighth District determined that expert
testimony establishing the reliability of the scientific principles underlying laser-
speed-measuring-device technology is not required for a court to admit into
evidence the results indicated by such a device. Id. at ¶ 23. The court reasoned that
laser speed detection works on the same scientific principles as radar speed
detection, which we deemed scientifically established in Ferell. Id. And challenges
based on whether the device involved in a particular case had been properly
maintained or used, and challenges based on the qualifications of the person who
used the device, involve the sufficiency and weight of the evidence, not its
admissibility. Id. at ¶ 10, 24.

SUPREME COURT OF OHIO
{¶ 5} Recognizing that this court had not yet determined whether the results
of a laser speed-measuring device are admissible without expert testimony
establishing, or the court taking judicial notice of, the reliability of the scientific
principles underlying the technology, the Eighth District certified that a conflict
existed between its decision in this case and the decisions of the courts of appeals
in State v. Cleavenger, 2018-Ohio-446, 93 N.E.3d 1027, ¶ 34 (7th Dist.), and In re
Z.E.N., 4th Dist. Scioto No. 18CA3826, 2018-Ohio-2208, ¶ 19-24. Id. at ¶ 27.
{¶ 6} This court determined that a conflict existed and ordered the parties
to brief the following issue:
“Whether the results of any speed measuring device, using either
radar or laser technology, [are] admissible without expert testimony
establishing, or the taking of judicial notice of, the scientific
reliability of the principles underlying that technology.”
2019-Ohio-768, 154 Ohio St.3d 1520, 118 N.E.3d 257, quoting 2018-Ohio-5028 at
¶ 27.
Analysis
{¶ 7} Rodojev urges this court to answer the certified question in the
negative, reverse the judgment of the court of appeals, and hold that sufficient proof
of the reliability of the scientific principles underlying laser speed-measuring
devices is required in each case, either through expert testimony or judicial notice
under Evid. R. 201. He argues that if we permit the admission of the results of a
laser speed-measuring device into evidence without that foundation, no proof of
reliability will be required respecting the most vital evidence in speeding-offense
cases.
{¶ 8} We disagree with Rodojev and note from the outset that other than his
challenge to the admissibility of the test results, he has not argued or presented any
4
January Term, 2020
evidence suggesting that the reliability of the scientific principles underlying laser
speed-measuring devices is invalid or even suspect. However, as the Eighth
District noted in its decision, this court has not addressed the reliability of the
scientific principles underlying radar speed-measuring devices since 1958 when we
decided Ferell. See 2018-Ohio-5028 at ¶ 26. We additionally note that we have
not addressed the admissibility of the results of laser speed-measuring devices
based on the reliability of the scientific principles underlying the technology.
Radar Speed Devices
{¶ 9} In E. Cleveland v. Ferell, this court took judicial notice of the
reliability of the scientific principles underlying stationary radar speed-measuring
devices. 168 Ohio St. at 303, 154 N.E.2d 630. British physicist James Clark
Maxwell began experimenting with radar, the letters of which stand for “radio
detection and ranging,” in the 1860s. Ryan V. Cox & Carl Fors, Admitting Light
Detection and Ranging (LIDAR) Evidence in Texas: A Call for Statewide Judicial
Notice, 42 St. Mary’s L.J. 837, 842-843 (2011). Radar works on the principle of
bouncing radio waves traveling at the speed of light off a reflective object at a fixed
frequency. Id. at 842. Radar uses long wavelength light from the radio portion of
the electromagnetic spectrum. Daniel Y. Gezari, Use of Lasers in Speed
Measurement, in 1 Campbell, Defense of Speeding, Reckless Driving and Vehicular
Homicide, Section 9a.02 (2020). Radar speed-measuring devices send out a
continuous beam of waves at a fixed frequency.2 Ferell at 300. When the waves
are intercepted by a moving object, the frequency of the waves changes “in such a
ratio to the speed of the intercepted object that, by measuring the change of
frequency, the speed may be determined.” Id. This is known as the “Doppler
2. The frequencies used by police for radar speed-measuring devices are established and maintained
by the Federal Communications Commission (“FCC”). Law-enforcement agencies purchase radar
speed-measuring devices that are built to operate at the frequencies dictated by the FCC. Cox &
Fors, 42 St. Mary’s L.J. at 843.

SUPREME COURT OF OHIO
effect”—a common example of which is the change in pitch that can be heard when
a vehicle with its horn or siren sounding passes the listener. See id.
{¶ 10} By the time this court decided Ferell, the Doppler effect had been
used for nearly a century to calculate the speed of moving objects. Id. Thus, we
held in Ferell that the results of radar speed-measuring devices are admissible
without expert testimony, just as photographs, X-rays, electroencephalographs, and
speedometer readings had been deemed admissible without expert testimony. Id.
at 303. However, we determined that the sufficiency of the evidence regarding the
accuracy of the device and the qualifications of the person who used the device
remained matters to be considered by the factfinder on a case-by-case basis. Id.
{¶ 11} Sometime after this court’s decision in Ferell, law-enforcement
officers began using moving radar speed-measuring devices. Cleavenger, 2018-
Ohio-446, 93 N.E.3d 1027, at ¶ 13. In Cleavenger, the Seventh District held that
pursuant to this court’s decision in Ferell, the results of radar speed-measuring
devices (Doppler devices), whether the device was stationary or moving, are
admissible without expert testimony on the reliability of the scientific principles
involved in the technology. Id. at ¶ 34.
{¶ 12} Like stationary radar speed-measuring devices, moving radar speed-
measuring devices also operate using the Doppler effect, but moving radar speed-
measuring devices are usually mounted inside of the police vehicle and can be used
while the police vehicle is moving. Cox & Fors, 42 St. Mary’s L.J. at 842-843,
846; see also Cleveland v. Tisdale, 8th Dist. Cuyahoga No. 89877, 2008-Ohio-
2807, ¶ 16. Differences in the devices include that a moving radar speed-measuring
device must compensate for the speed of the police vehicle in relation to the vehicle
it is tracking. See State v. Wilcox, 40 Ohio App.2d 380, 383-384, 319 N.E.2d 615
(10th Dist.1974). And rather than tracking an individual vehicle, a moving radar
speed-measuring device usually tracks the fastest moving object within its range.
6
January Term, 2020
Cox & Fors, 42 St. Mary’s L.J. at 846. Because of this, the officer must visually
determine which vehicle within the device’s range is traveling the fastest. Id.
{¶ 13} Both of these differences are device-specific and still require the
factfinder to determine whether the evidence presented concerning the accuracy of
the device and the qualifications of the person who used it is sufficient to support a
conviction based on the device’s results. See Ferell, 168 Ohio St. at 303, 154
N.E.2d 630. But neither difference calls into question the reliability of the scientific
principles underlying radar speed-measuring technology: when radio waves are
intercepted by a moving object, the frequency of the waves changes “in such a ratio
to the speed of the intercepted object that, by measuring the change of frequency,
the speed may be determined.” Id. at 300. Accordingly, we approve and follow
our decision in Ferell that the results of a radar speed-measuring device may be
admitted into evidence without expert testimony establishing the reliability of the
scientific principles underlying the technology. Id. at 303.
Laser Speed Devices
{¶ 14} In In re Z.E.N., the Fourth District determined that for a defendant
to be convicted of a speeding offense based on the results of a laser speed-
measuring device, there must be sufficient evidence presented at trial showing that
the device is scientifically reliable. 2018-Ohio-2208 at ¶ 18. It further determined
that the scientific reliability of a speed-measuring device can be established through
expert testimony or judicial notice. Id. The court determined that the state had
failed to present sufficient evidence of the laser speed-measuring device’s
reliability to support the defendant’s speeding conviction. Id. at ¶ 23-24.
{¶ 15} Laser, the letters of which stand for “light amplification by
stimulated emission of radiation,” was first theorized by Albert Einstein in 1917
and finally developed by American physicist Theodore Maiman in 1960. Cox &
Fors, 42 St. Mary’s L.J. at 848. Laser speed-measuring devices were first offered
7
SUPREME COURT OF OHIO
for use to law-enforcement officers in 1991.3 Id. Different from the longer
wavelength light used by radar devices, a laser device uses shorter wavelength light
from the infrared portion of the electromagnetic spectrum. Id. at 849.
{¶ 16} Laser speed-measuring devices transmit a series of very short pulses
of infrared light in a very narrow beam. Gezari, Use of Lasers in Speed
Measurement, at Section 9a.02. The pulses of light reflect back from the vehicle
and are detected by an infrared sensor in the device. Id. The device records the
time it takes for each pulse, traveling at the speed of light, to reach the vehicle and
return to the device, and it calculates the distance to the vehicle using the travel
time and constant value of the speed of light. Id. The device makes multiple
distance measurements in a fraction of a second. Id. It then calculates the speed of
the vehicle from the distance and time data it gathered using the formula: velocity
= distance ÷ time. Id.
{¶ 17} We are satisfied that the scientific principles underlying laser speed-
measuring devices are sufficiently reliable and hold that the results of a laser speed-
measuring device are admissible in Ohio courts without expert testimony
establishing their reliability or the court taking judicial notice of the scientific
principles underlying that technology. Our decision on this issue is in accordance
with decisions from courts in several other states. See, e.g., Goldstein v. State, 339
Md. 563, 576-577, 664 A.2d 375 (1995); People v. Mann, 397 Ill.App.3d 767, 772,
922 N.E.2d 533 (2010); State v. Williamson, 144 Idaho 597, 600, 166 P.3d 387
3. The National Highway Traffic Safety Administration and the International Association of Chiefs
of Police test and approve radar speed-measuring devices in accordance with United States
Department of Transportation standards and publish their findings in a Conforming Product List
(“CPL”). Cox & Fors, 42 St. Mary’s L.J. at 847. Although state and local law-enforcement agencies
are not required to purchase devices listed on the CPL, only devices on the CPL are eligible for
purchase using federal Highway Safety Grant Program funds. National Highway Traffic Safety
Administration, Conforming Product List (Jan. 20, 2020),

{¶ 18} Other substantive challenges to the results of a laser speed-
measuring device—including challenges involving the angle at which the officer
held the device in relation to the targeted vehicle, the device’s accuracy-validation
algorithms, the device’s calibration and maintenance schedule, and the officer’s
qualifications to use the device—implicate the sufficiency and weight of the
evidence, not its admissibility. See State v. Adams, 103 Ohio St.3d 508, 2004-Ohio-
5845, 817 N.E.2d 29, ¶ 80 (a court may admit DNA evidence without conducting
a preliminary hearing; questions regarding the reliability of DNA evidence in a
particular case go to the weight of the evidence, not its admissibility). Our decision
today, that the results of a speed-measuring device using radar or laser technology
are admissible in court without expert testimony establishing, or the court taking
judicial notice of, the reliability of the scientific principles underlying that
technology, leaves determinations involving the sufficiency and weight of the
evidence to be made on a case-by-case basis.
Conclusion
{¶ 19} We hold that the results of a speed-measuring device using either
radar or laser technology are admissible in court without expert testimony
establishing, or the court taking judicial notice of, the reliability of the scientific
principles underlying that technology. However, the factfinder is required to
determine whether the evidence presented concerning the accuracy of the particular
speed-measuring device and the qualifications of the person who used it is
sufficient to support a conviction based on the device’s results. Accordingly, we
answer the certified question in the affirmative and affirm the judgment of the
Eighth District.

SUPREME COURT OF OHIO
Judgment affirmed.
O’CONNOR, C.J., and FRENCH, FISCHER, DEWINE, and DONNELLY, JJ.,
concur.
KENNEDY, J., dissents, with an opinion.
_________________
KENNEDY, J., dissenting.
{¶ 20} The majority holds today that the state no longer needs to prove the
scientific reliability of a laser speed-measuring device before the results of such a
device can be used to convict a driver of a speeding offense. That is, the majority
makes a policy determination to make it simpler for the state to make its case
against defendants charged with speeding offenses. In reaching its conclusion, the
majority relies on this court’s decision in E. Cleveland v. Ferell, 168 Ohio St. 298,
154 N.E.2d 630 (1958), a case that predates both the Ohio Rules of Evidence and
modern, leading caselaw like Daubert v. Merrell Dow Pharmaceuticals, Inc., 509
U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), and Miller v. Bike Athletic Co.,
80 Ohio St.3d 607, 687 N.E.2d 735 (1998), which established standards that Ohio
courts ordinarily use in evaluating the reliability of scientific evidence. Because
the majority gives the state a free pass on one of the most essential parts of proving
its case for a speeding offense—the reliability of the device that produced the
results that will in effect determine the defendant’s guilt or lack of guilt—I dissent.
{¶ 21} This case comes to us through the judgment of the Eighth District
Court of Appeals to certify a conflict among Ohio’s appellate districts regarding
whether the state is required to prove the scientific reliability of laser speed-
measuring devices before their results can be used in the prosecution of speeding
cases. We recognized the conflict and ordered briefing on this issue:
“[W]hether the results of any speed measuring device, using either
radar or laser technology, is admissible without expert testimony
10
January Term, 2020
establishing, or the taking of judicial notice of, the scientific
reliability of the principles underlying the technology.”
2019-Ohio-768, 154 Ohio St.3d 1520, 118 N.E.3d 257, quoting 2018-Ohio-5028,
¶ 27.
{¶ 22} In Ohio, only the Eighth District has determined that the answer to
that question is yes, 2018-Ohio-5028 at ¶ 23, although it has been at odds with itself
over the years. See Beachwood v. Joyner, 2012-Ohio-5884, 984 N.E.2d 388, ¶ 15
(8th Dist.) (trial court erred by admitting testimony regarding results of moving
radar speed-measuring device without the benefit of expert testimony when the
scientific reliability of the particular model had not been established in a previous
case). Ohio’s other appellate districts that have addressed the issue have
determined that the state must prove the reliability of a laser speed-measuring
device. See, e.g., State v. McKay, 1st Dist. Hamilton No. C–130657, 2014-Ohio-
2027, ¶ 10; State v. Helke, 2015-Ohio-4402, 46 N.E.3d 188, ¶ 40 (2d Dist.); State
v. Zhovner, 2013-Ohio-749, 987 N.E.2d 333, ¶ 25-26 (3d Dist.); In re Z.E.N., 2018-
Ohio-2208, 114 N.E.3d 594, ¶ 18 (4th Dist.); State v. Lapso, 5th Dist. Ashland No.
2007-COA-045, 2008-Ohio-4489, ¶ 31-32; State v. Jampani, 6th Dist. Erie No. E-
13-004, 2013-Ohio-5070, ¶ 19-20; Campbell v. Rosario, 2018-Ohio-337, 101
N.E.3d 681, ¶ 16 (7th Dist.); State v. Freiteg, 9th Dist. Wayne No. 07CA0082,
2008-Ohio-6573, ¶ 14-15; Columbus v. Dawson, 10th Dist. Franklin No. 99AP-
589, 2000 WL 271766, *2-3 (Mar. 14, 2000); State v. Allenbaugh, 11th Dist.
Ashtabula No. 2019-A-0017, 2020-Ohio-68, ¶ 41; State v. Starks, 196 Ohio App.3d
589, 2011-Ohio-2344, 964 N.E.2d 1058, ¶ 21-22 (12th Dist.). In those districts, the
scientific reliability of a speed-measuring device can be established through expert
testimony or judicial notice. See, e.g., Rosario at ¶ 16.
{¶ 23} Evid.R. 201(B) establishes the kind of facts that can be judicially
noticed: “A judicially noticed fact must be one not subject to reasonable dispute in
11
SUPREME COURT OF OHIO
that it is either (1) generally known within the territorial jurisdiction of the trial
court or (2) capable of accurate and ready determination by resort to sources whose
accuracy cannot reasonably be questioned.” In Cincinnati v. Levine, 158 Ohio
App.3d 657, 2004-Ohio-5992, 821 N.E.2d 613 (1st Dist.), the First District
determined that there are three general ways for a trial court to take judicial notice
of the reliability of a speed-measuring device. The trial court may rely on “(1) a
reported [trial court] decision, (2) a reported or unreported case from the appellate
court, or (3) the previous consideration of expert testimony about a specific device
where the trial court notes it on the record.” Id. at ¶ 10.
{¶ 24} If the scientific reliability of a particular speed-measuring device has
not previously been established in an appellate district, a trial court in that district
may instead also consider expert testimony regarding the device’s reliability
pursuant to Evid.R. 702. Evid.R. 702 “vest[s] the trial court with the role of
gatekeeper” and part of “[t]his gatekeeping function imposes an obligation upon a
trial court to assess * * * the reliability of an expert’s methodology.” Terry v.
Caputo, 115 Ohio St.3d 351, 2007-Ohio-5023, 875 N.E.2d 72, ¶ 24. In evaluating
scientific reliability, the court applies the factors set forth in Daubert, 509 U.S. 579,
113 S.Ct. 2786, 125 L.Ed.2d 469:
The trial court should first assess whether the method or
theory relied upon has been tested. [Daubert] at 593, 113 S.Ct.
2786, 125 L.Ed.2d 469. Next, it should consider whether the theory
has been the subject of peer review, and then whether the method
has a known or potential error rate. Id. at 593-594, 113 S.Ct. 2786,
125 L.Ed.2d 469. Finally, Daubert instructs trial courts to look at
whether the theory has gained general acceptance in the scientific
community. Id. at 594, 113 S.Ct. 2786, 125 L.Ed.2d 469. None of
these factors, of course, is dispositive of the inquiry, and when
12
January Term, 2020
gauging the reliability of a given expert’s testimony, trial courts
should focus “solely on principles and methodology, not on the
conclusions” generated. Id. at 595, 113 S.Ct. 2786, 125 L.Ed.2d
469.
Caputo at ¶ 25, quoting Daubert at 595.
{¶ 25} The majority rejects the methods Ohio’s courts have been employing
for years to evaluate evidence gathered from laser speed-measuring devices and
dusts off Ferell, which involved radar speed-measuring devices, to apply it in a
different time to different technology. In doing so, the majority follows Ferell’s
dubious reasoning and converts the role of the trial court from gatekeeper to
facilitator.
{¶ 26} In Ferell, this court held that readings from stationary radar speed-
detection devices “may be accepted into evidence * * * without the necessity of
offering expert testimony as to the scientific principles underlying them.” 168 Ohio
St. at 303, 154 N.E.2d 630. That holding seems tied more to convenience than to
science and the law.
{¶ 27} In Ferell, the court began its analysis by setting forth the law
regarding the use of scientific instruments in court:
Professor Wigmore, in The Science of Judicial Proof, at page
450, said:
“* * * since the additions made possible to our unaided
senses are due to the use of instruments constructed on knowledge
of scientific laws, it is plain that the correctness of the data thus
obtainable must depend upon the correctness of the instrument in
construction and the ability of the technical witness to use it. Hence,
13
SUPREME COURT OF OHIO
the following three fundamental propositions apply to testimony
based on the use of all such instruments:
A. The type of apparatus purporting to be constructed on
scientific principles must be accepted as dependable for the
proposed purpose by the profession concerned in that branch of
science or its related art. This can be evidence by qualified expert
testimony; or, if notorious, it will be judicially noticed by the judge
without evidence.
B. The particular apparatus used by the witness must be one
constructed according to an accepted type and must be in good
condition for accurate work. This may be evidenced by a qualified
expert.
C. The witness using the apparatus as the source of his
testimony must be one qualified for its use by training and
experience.”
(Emphasis sic.) Id. at 301, quoting Wigmore, The Science of Judicial Proof 450
(1937). But then the court quickly abandoned the Wigmore approach, instead
joining a few other courts in deciding that the requirement of expert testimony to
establish the scientific reliability of an instrument is too onerous. Id. at 301-303.
It should be noted that there seems to have been lacking at the time that Ferell was
decided—which was prior to the adoption of the Ohio Rules of Evidence—the
robust reliance on judicial notice that Ohio courts apply when facing the issue
today. See id. The court’s focus in Ferell was therefore on removing the
requirement of expert testimony to prove scientific reliability. As this court stated,
“There would appear to be developing a realization upon the part of courts that such
expert testimony is no longer required.” Id. at 302.
14
January Term, 2020
{¶ 28} In reaching its decision in Ferell, this court looked to the decision
from the Supreme Court of New Jersey in State v. Dantonio, 18 N.J. 570, 115 A.2d
35 (1955):
The New Jersey court, quoting from Woodbridge, Radar in
the Courts, 40 Virginia Law Review, 809, [wrote]:
“ ‘Under the Uniform Rules of Evidence, already approved
by the American Bar Association at its 1953 meeting, judicial notice
“shall be taken without request by a party * * * of such specific facts
and propositions of generalized knowledge as are so universally
known that they cannot reasonably be the subject of dispute.” Radar
speed meters are now in this category. Why should the time of
experts be wasted and the expenses of litigation be increased by
compelling such men to appear in court after court telling the same
truths over and over? While it is agreed that every reasonable doubt
about the accuracy of new developments should promptly be
resolved against them in the absence of expert evidence, there is no
longer any such doubt concerning radar. Rather, the applicable
maxim should now be, “What the world generally knows a court of
justice may be assumed to know.” ’ ”
Ferell at 302, quoting Dantonio at 578-579, quoting Woodbridge, Radar in the
Courts, 40 Va.L.Rev. 809, 814 (1955).
{¶ 29} In Ferell, this court also cited a decision of the highest court in New
York:
The courts of New York, which have been reluctant to eliminate the
necessity for expert testimony * * * have, as of January 16, 1958,
15
SUPREME COURT OF OHIO
concluded the principle for that state. In the case of People v. Magri,
3 N.Y.2d 562, 170 N.Y.S.2d 335, 147 N.E.2d 728, the Court of
Appeal said:
“We think the time has come when we may recognize the
general reliability of the radar speed meter as a device for measuring
the speed of a moving vehicle, and that it will no longer be necessary
to require expert testimony in each case as to the nature, function or
scientific principles underlying it.”
168 Ohio St. at 302-303, 154 N.E.2d 630, quoting Magri at 566.
{¶ 30} There is no indication that when Ferell was decided in 1958, Ohio
courts were—as they are now—regularly taking judicial notice of the reliability of
speed-measuring devices after they had been deemed reliable in a prior case. In
regard to laser speed-measuring devices, a court’s taking judicial notice under
Evid.R. 201(B) of caselaw from the trial court’s appellate district establishing a
device’s reliability makes it relatively easy for the state to avoid having to introduce
expert testimony in every case involving a speed-measuring device. Ferell was
decided relatively early in the development of speed-detection technology and
before the adoption of the Ohio Rules of Evidence. The rationale in Ferell does
not fit today.
{¶ 31} Ferell was decided in an era during which there was a different
standard for what scientific expert testimony had to prove. In that era, the leading
case dealing with the admissibility of scientific evidence in a criminal trial was Frye
v. United States, 293 F. 1013 (D.C.Cir.1923). The Frye court determined that the
party offering the testimony must establish that the scientific principle involved has
“gained general acceptance in the particular field in which it belongs.” Id. at 1014;
see also State v. Springer, 8th Dist. Cuyahoga No. 33523, 1975 WL 182452, *2
(Apr. 24, 1975) (“The leading case dealing with the admissibility of scientific
16
January Term, 2020
evidence in a criminal trial is Frye”). And that standard of general acceptance
dovetails with what this court decided in Ferell; although the court in Ferell did not
cite Frye, it did rely on the general knowledge and acceptance of the efficacy of
radar speed-measuring devices to reach its conclusion.
{¶ 32} But the admissibility of expert testimony is now controlled by
Evid.R. 702, which does not allow expert testimony to be admitted merely on
general acceptance of the scientific principle or technology in the particular field in
which it belongs. Under the Ohio Rules of Evidence, “the inquiry as to reliability
is appropriately directed, not to the correctness or credibility of the conclusions
reached by the expert witness, but to the reliability of the principles and methods
used to reach those conclusions.” 1994 Staff Note, Evid.R. 702.
{¶ 33} In Miller, 80 Ohio St.3d at 611, 687 N.E.2d 735, this court adopted
from Daubert four factors to be considered by a court in evaluating the reliability
of scientific evidence: (1) whether the theory or technique has been tested, (2)
whether it has been subjected to peer review, (3) whether there is a known or
potential rate of error, and (4) whether the methodology has gained general
acceptance. As this court later stated, “[b]oth the United States Supreme Court in
Daubert and this court in Miller were careful to emphasize that none of these factors
is a determinative prerequisite to admissibility.” State v. Nemeth, 82 Ohio St.3d
202, 211, 694 N.E.2d 1332 (1998), citing Miller at 612-613, and Daubert, 509 U.S.
at 593, 113 S.Ct. 2786, 125 L.Ed.2d 469. Ferell purported to obviate the necessity
for expert testimony in radar speed-measuring device cases, but its reasoning
cannot obviate the necessity of expert testimony under the later adopted Evid.R.
702. The majority’s decision is not tied in any way to the Ohio Rules of Evidence.
{¶ 34} Moreover, the logic and workability of Ferell are questionable.
Although the scientific reliability of laser speed-measuring technology in general
might be settled, that does not mean that any particular device that the state claims
is a laser speed-measuring device actually employs that settled science. The
17
SUPREME COURT OF OHIO
majority today accepts the reliability of the science underlying every laser speed-
measuring device. But to which devices do the majority’s acceptance apply? Who
determines the baseline question of what constitutes a laser speed-measuring
device? Is it the police officer? How does the person who identifies the device as
a laser speed-measuring device make that identification unless he or she knows the
scientific principles upon which the identification is based?
{¶ 35} Finally, the Ferell court reasoned that accepting the reliability of
radar speed-measuring devices was the same as accepting the reliability of other
types of scientific principles or devices that might play a role in litigation:
We are in accord with the trend of the most recent decisions
that readings of a radar speed meter may be accepted in evidence,
just as we accept photographs, X rays, electroencephalographs,
speedometer readings, and the like, without the necessity of offering
expert testimony as to the scientific principles underlying them.
168 Ohio St. at 303, 154 N.E.2d 630. The majority’s opinion today repeats that
language, seemingly approvingly. In my view, the recognized reliability of
photographs, X-rays, electroencephalographs, and speedometers is owed to the
reliance that people put in those devices outside of litigation; those instruments
were not designed to achieve convictions for the state. We trust them in court
because we trust them in life to perform the everyday things they were designed to
do outside the courtroom; their use in court is tangential to their normal purposes.
Further, a typical trier of fact knows from experience that a camera captures a visual
moment of reality, that an X-ray reveals the skeletal structure that we can feel, and
that the sweeping second hand of a watch coincides with our sense of the passage
of time. And unlike the use of speed-measuring devices in speeding cases, those
instruments do not provide evidence going to the ultimate determination of guilt or
18
January Term, 2020
lack of guilt in most cases. A speed-measuring device, on the other hand, is
designed to provide evidence against drivers—it answers the ultimate question of
guilt or lack of guilt in a speeding case.
{¶ 36} Indeed, R.C. 4511.091(C)(1) precludes a person from being arrested,
charged, or convicted based on a police officer’s unaided visual estimation of the
speed of a motor vehicle and requires the officer to use a “stopwatch, radar, laser,
or other electrical, mechanical, or digital device to determine the speed of a motor
vehicle.” A laser speed-measuring device registers a number on the device’s
screen, and if the number is high enough then the vehicle’s driver can be charged
and convicted for violating the law. There is no logical connection between the
number that appears on the screen and a person’s observance of a moving vehicle.
Without an expert’s explanation of how a particular speed-measuring device works,
we have no reason to trust that the number on the screen is an accurate
determination of a vehicle’s speed or that the device’s results are reliable.
{¶ 37} We are not faced with a tide of decisions from other jurisdictions
that allow the results of a laser-speed measuring device to be admitted into evidence
without first establishing the device’s reliability. The majority lists decisions from
just three states’ highest courts announcing a rule like the majority announces
today: Idaho, Maryland, and Vermont. Other states deal with the issue legislatively.
For instance, a Georgia statute states that laser speed-measuring devices that have
been approved by its department of public safety and included on a list prepared by
the department “shall be considered scientifically acceptable and reliable as a speed
detection device and shall be admissible for all purposes in any court, judicial, or
administrative proceedings in this state.” Ga.Code Ann. 40-14-17. Connecticut
has a similar statute. Compare Conn.Gen.Stat. 14-219c (providing prima facie
presumption of device’s accuracy if device has been approved by commissioner of
emergency services and public protection). Ohio provides a similar list of approved
breathalyzer devices used to measure breath-alcohol concentration. Ohio
19
SUPREME COURT OF OHIO
Adm.Code 3701-53-02. Both Virginia and Maine have enacted statutes providing
that the results of a laser speed-measuring device are prima facie evidence that the
vehicle measured was traveling at the reported speed. Va.Code Ann. 46.2-882;
Me.Rev.Stat.Ann. Title 29-A, Section 2075.
{¶ 38} Those are policy decisions appropriately and best dealt with by the
General Assembly. “It is a fundamental precept of our tripartite form of state
government that the General Assembly is the ultimate arbiter of public policy.”
Cleveland v. State, 157 Ohio St.3d 330, 2019-Ohio-3820, 136 N.E.3d 466, ¶ 40.
Absent legislation by the General Assembly, we should address the use of laser
speed-measuring devices in Ohio’s courts by employing the Ohio Rules of
Evidence. The state should have to demonstrate that the laser speed-measuring
devices it employs to convict defendants charged with speeding offenses are
reliable. Once the reliability of a particular device has been proven in court through
expert testimony, the court can thereafter take judicial notice to recognize the
reliability of the device. But the court should not be permitted to cut corners by
hearing no evidence of the reliability of a particular speed-measuring device when
the device’s reliability has not previously been established.
{¶ 39} In this case, I would hold that the lack of expert-testimony
foundation regarding the reliability of the speed-measuring device used to convict
appellant, Joseph G. Rodojev, constituted plain error implicating the sufficiency of
the evidence. See, e.g., Z.E.N., 2018-Ohio-2208, 114 N.E.3d 594, at ¶ 22,
citing State v. Cleavenger, 2018-Ohio-446, 93 N.E.3d 1027, ¶ 25 (7th Dist.).
Accordingly, I would reverse the Eighth District’s judgment and vacate Rodojev’s
conviction. Therefore, I dissent.
