JUDGE AMY J. OLIVER authored this Opinion, in which JUDGES
GREGORY K. ORME and MICHELE M. CHRISTIANSEN FORSTER
concurred.
OLIVER, Judge:
¶1 Armando Ayala and Ashlie Mauger were driving together
in Ayala’s truck when they were involved in a vehicle collision
with Officer Ethan Andrus of the Unified Police Department of
Greater Salt Lake (UPD). Ayala and Mauger sued UPD and
Andrus, who in turn asserted they were immune from suit under
the Governmental Immunity Act of Utah. The district court
agreed, granting summary judgment to UPD and Andrus. On
appeal, Ayala and Mauger contend that summary judgment was
Ayala v. Unified Police Department
improper because there were genuine issues of material fact as to
whether the statutory requirements for immunity had been met.
We agree with Ayala and Mauger, and we therefore reverse the
grant of summary judgment and remand the case for further
proceedings.
BACKGROUND 1
The Accident
¶2 On the afternoon of August 4, 2020, Ayala was driving his
truck eastbound on 7000 South in West Jordan, Utah, with
Mauger in the passenger seat. At the same time, several UPD
officers, including Andrus, were responding to another agency’s
call for assistance with the pursuit of a fleeing criminal suspect.
The UPD officers were attempting to get ahead of the fleeing
vehicle in order to deploy spike strips to deflate its tires.
¶3 As Ayala approached the intersection of 7000 South and
1300 West, he observed one of the UPD officers enter the
intersection with emergency lights and siren activated. The officer
made a left-hand turn, going from westbound 7000 South to
southbound 1300 West. A second UPD officer approached
moments later, traveling southbound on 1300 West with lights
and siren activated. That officer “slowed down to a creep and then
went through” the intersection.
¶4 Ayala—believing the coast was now clear and having a
green light to proceed eastbound—then entered the intersection,
1. “In reviewing a district court’s grant of summary judgment, we
view the facts and all reasonable inferences drawn therefrom in
the light most favorable to the nonmoving party and recite the
facts accordingly.” Crosbie v. 750 W. Owners Ass’n, 2026 UT App 9,
n.1, 586 P.3d 10 (cleaned up).
20250290-CA,
20250291-CA 2 2026 UT App 139
Ayala v. Unified Police Department
where he was struck by a third UPD officer, Andrus. Andrus was
driving southbound on 1300 West, directly behind the second
officer, when he entered the intersection against a red light and
struck Ayala’s vehicle. He had his emergency lights activated and
later claimed that he had his siren activated as well, though there
was some dispute on this point. A nearby gas station security
camera captured the entire incident on video. While lacking
sound, the video shows all three officers traversing the
intersection with emergency lights flashing, followed by the
collision between Ayala and Andrus.
The Lawsuit
¶5 Ayala and Mauger sued UPD and Andrus for negligence,
seeking damages related to the injuries they sustained in the
collision. A few months before trial was set to begin, UPD and
Andrus filed a motion for summary judgment, invoking the
Governmental Immunity Act of Utah. See Utah Code § 63G-7-
201(4)(r). They argued the undisputed evidence showed that
“Officer Andrus was driving his police vehicle in accordance
with” all applicable requirements—such as activating his
emergency lights and siren and acting “in a reasonably prudent
manner”—thus rendering UPD immune from suit. In particular,
they asserted that there could be no dispute Andrus acted
reasonably “because he was operating his vehicle exactly like the
two officers who went safely through the intersection before him”
and that there was “no other admissible evidence that Officer
Andrus was acting unreasonably under the circumstances.”
¶6 Ayala and Mauger opposed the motion, asserting there
was a genuine dispute of fact as to whether the statutory
requirements for governmental immunity had been met. As to
whether Andrus had acted reasonably, they averred that he had
failed to slow down sufficiently before entering the intersection
and, furthermore, had failed to comply with the emergency
20250290-CA,
20250291-CA 3 2026 UT App 139
Ayala v. Unified Police Department
driving policy in the UPD Policy Manual. They presented a copy
of the emergency driving policy as well as a disciplinary report
that included UPD’s finding that Andrus violated the following
policy provisions:
• Policy 312.5: “Officers shall exercise sound judgment and
care with due regard for life and property when
responding to an emergency call. Officers shall reduce
speed at all street intersections to such a degree that they
shall have complete control of the vehicle.”
• Policy 312.5.1: “Members will slow to a safe and reasonable
speed (not greater than 10 MPH), and if necessary stop
before proceeding through intersections against a red light
or stop signs, and shall determine that all cross traffic has
yielded before crossing said intersection.”
¶7 Once the motion for summary judgment had been fully
briefed, UPD filed a request to submit the motion to the court and
asked for oral argument. 2 Later that same day—and without
holding oral argument—the district court granted the motion in a
single-sentence written ruling: “After review of the pleadings,[3]
the Court grants the Motion for Summary Judgment as
Defendants have established facts to show they complied with the
statutory requirements for governmental immunity under U.C.A.
§ 63G-7-201(4)(r) and § 41-6a-212.”
2. Throughout the remainder of our opinion, we will use UPD to
refer to UPD and Andrus collectively.
3. Although the district court referred to “the pleadings,” which
in this case would have been only the complaint and answer, see
Utah R. Civ. P. 7(a), presumably it meant the moving papers in
support of and in opposition to summary judgment.

Ayala v. Unified Police Department
ISSUE AND STANDARD OF REVIEW
¶8 Ayala and Mauger assert the district court erred by
granting UPD’s motion for summary judgment. “We review
summary judgment decisions for correctness, viewing the facts in
a light most favorable to the losing party below and giving no
deference to the district court’s conclusions of law.” Brinkerhoff v.
Fleming, 2023 UT App 92, ¶ 10, 536 P.3d 156 (cleaned up).
ANALYSIS
¶9 Summary judgment is appropriate only “if the moving
party shows that there is no genuine dispute as to any material
fact and the moving party is entitled to judgment as a matter of
law.” Utah R. Civ. P. 56(a). Ayala and Mauger assert that the
district court’s grant of summary judgment was improper
because there were genuine issues of material fact as to whether
the statutory requirements for governmental immunity had been
met.
¶10 To succeed on a motion for summary judgment, a moving
party who “would bear the burden of proof at trial . . . must
establish each element” of a claim in order to show entitlement to
judgment as a matter of law. Vanderwood v. Woodward, 2019 UT
App 140, ¶ 32, 449 P.3d 983 (cleaned up). The movant “must
produce affirmative evidence that demonstrates an absence of a
genuine issue of material fact,” and “if the movant does so, then
the burden shifts to the nonmoving party to present evidence that
is sufficient to establish a genuine issue of material fact.” Id.
(cleaned up). If the district court “finds that there is a genuine
issue of material fact that bears on its legal determination or if it
finds, as a matter of law based on the undisputed facts, that the
moving party is not entitled to a legal ruling in its favor,” then it
must deny the motion. Normandeau v. Hanson Equip., Inc., 2009 UT
44, ¶ 9, 215 P.3d 152.
20250290-CA,
20250291-CA 5 2026 UT App 139
Ayala v. Unified Police Department
¶11 Here, UPD bore the burden of proving its governmental
immunity defense. See, e.g., Fritsche v. Deer Valley Ridge at Silver
Lake Ass’n of Unit Owners, 2022 UT App 11, ¶ 40, 504 P.3d 761
(“When a party raises an affirmative defense, it bears the burden
of proof for that defense.”); Salo v. Tyler, 2018 UT 7, ¶ 33 n.2, 417
P.3d 581 (“The assertion of governmental immunity is an
affirmative defense . . . .”). UPD was thus required to “produc[e]
affirmative evidence in support of the essential elements” of its
defense when it sought summary judgment on that ground. Salo,
2018 UT 7, ¶ 26. Upon UPD’s production of such evidence, the
burden then shifted to Ayala and Mauger “to establish a genuine
issue of material fact.” Vanderwood, 2019 UT App 140, ¶ 32
(cleaned up).
¶12 The district court determined that UPD had “established
facts to show they complied with the statutory requirements for
governmental immunity,” but offered no further explanation.
Accordingly, we do not know what facts the district court
believed were established. 4 But on our review of the record, we
identify multiple disputes of material fact that precluded the
conclusion that UPD was immune from suit as a matter of law.
I. The Governmental Immunity Act of Utah
¶13 The Governmental Immunity Act of Utah provides, in
relevant part,
A governmental entity, its officers, and its
employees are immune from suit, and immunity is
not waived, for any injury proximately caused by a
negligent act or omission of an employee committed
within the scope of employment, if the injury arises
4. While we owe no deference to a district court’s grant of
summary judgment, we nonetheless benefit from the insight of
our district court bench when additional explanation is offered.
20250290-CA,
20250291-CA 6 2026 UT App 139
Ayala v. Unified Police Department
out of or in connection with, or results from: . . . the
operation of an emergency vehicle, while being
driven in accordance with the requirements of
Section 41-6a-212.
Utah Code § 63G-7-201(4), (4)(r).
¶14 Utah Code section 41-6a-212, in turn, identifies various
privileges and requirements related to the operation of an
emergency vehicle. It provides that when “responding to an
emergency call,” “in the pursuit of an actual or suspected violator
of the law,” or “responding to . . . a fire alarm,” id. § 41-6a-
212(2)(a)–(c), “[t]he operator of an authorized emergency vehicle
may,” as relevant here, have the privilege of “proceed[ing] past a
red or stop signal or stop sign, but only after slowing down as
may be necessary for safe operation,” id. § 41-6a-212(3), (3)(b).
¶15 But certain requirements must be met in order for this
privilege to apply. The requirements differ somewhat depending
on whether the emergency vehicle operator is or is not “involved
in a vehicle pursuit.” Compare id. § 41-6a-212(4) (outlining
requirements for an emergency vehicle not involved in a vehicle
pursuit), with id. § 41-6a-212(5) (outlining requirements for an
emergency vehicle involved in a vehicle pursuit). When not
involved in a vehicle pursuit, the operator of an emergency
vehicle must “sound[] an audible signal under Section 41-6a-
1625” or “use[] a visual signal with emergency lights in
accordance with rules made under Section 41-6a-1601, which is
visible from in front of the vehicle.” Id. § 41-6a-212(4)(a)(i)–(ii). By
contrast, the operator of an emergency vehicle who is involved in
a vehicle pursuit is required to use both audible and visual signals,
see id. § 41-6a-212(5)(a)(i)(A)–(B), as well as have been trained per
his or her agency’s vehicle pursuit policy—the requirements of
which are further laid out in the statute, see id. § 41-6a-
212(5)(a)(ii)–(iii), (b). But in either case, section 41-6a-212 instructs
20250290-CA,
20250291-CA 7 2026 UT App 139
Ayala v. Unified Police Department
that, absent a limited exception, “the privileges granted under this
section do not relieve the operator of an authorized emergency
vehicle of the duty to act as a reasonably prudent emergency
vehicle operator under the circumstances.” Id. § 41-6a-212(7)(a).
¶16 In the present case, the parties do not dispute that, when
the collision occurred, Andrus was operating “an authorized
emergency vehicle” and “responding to an emergency call.” See
id. § 41-6a-212(2), (2)(a). UPD asserts that “Officer Andrus was not
involved in a vehicle pursuit” and was thus privileged to proceed
through the red light so long as he activated his emergency lights
or siren and acted reasonably. 5 But even if we assume, without
deciding, that UPD is correct on this point, UPD did not establish
its entitlement to judgment as a matter of law.
A. The Audible or Visual Signal Requirement
¶17 For an emergency vehicle operator not involved in a
vehicle pursuit, section 41-6a-212 requires the use of “an audible
signal under Section 41-6a-1625” or “a visual signal with
emergency lights in accordance with rules made under Section 41-
6a-1601, . . . visible from in front of the vehicle.” Utah Code § 41-
6a-212(4)(a)(i)–(ii). UPD claims there is no dispute as to this
element of its defense because the “security video clearly confirms
that all three officers had activated their emergency lights before
entering and traveling through the intersection.”
¶18 While the security video footage does show that Andrus’s
emergency lights were activated, noticeably absent from the
5. UPD appears to contend that assisting with another agency’s
vehicle pursuit—such as by attempting to place spike strips ahead
of a fleeing suspect—does not amount to being “involved in a
vehicle pursuit.” See Utah Code § 41-6a-212(4)(a); see also id. § 41-
6a-212(5)(a). But because Ayala and Mauger have not argued to
the contrary, we need not evaluate that contention here.
20250290-CA,
20250291-CA 8 2026 UT App 139
Ayala v. Unified Police Department
record is any evidence showing that Andrus’s emergency lights
were of the type required by the statute. Section 41-6a-1601 of the
Utah Code, cited in section 41-6a-212, instructs the Department of
Public Safety (DPS) to create rules “setting minimum standards
covering the design, construction, condition, and operation of
vehicle equipment,” including “standards for the emergency
lights of authorized emergency vehicles.” Id. § 41-6a-1601(2)(a),
(b)(iv). At no point did UPD attempt to establish that the
emergency lights atop Andrus’s police vehicle complied with any
applicable standards promulgated by DPS. But given the
applicable statutory requirement, it was required to do so to
obtain summary judgment.
¶19 The necessity of such a showing is illustrated by our
supreme court’s decision in Clegg v. Wasatch County, 2010 UT 5,
227 P.3d 1243. In Clegg, a sheriff’s deputy had struck another
vehicle with his patrol car while responding to an emergency call.
Id. ¶ 2. The parties did not dispute that the deputy’s emergency
lights and siren were activated at the time of the collision. Id. ¶ 16.
When the driver of the other vehicle sued the deputy and Wasatch
County for negligence, the county asserted immunity under the
Governmental Immunity Act of Utah and moved for summary
judgment, which the district court granted. Id. ¶ 3.
¶20 On appeal, the supreme court reversed the grant of
summary judgment, concluding a dispute of material fact
remained as to “the adequacy of the [deputy’s] audible and visual
signals.” Id. ¶ 7. At the time, the statutory requirements for an
emergency vehicle’s lights and siren, as referenced in the
Governmental Immunity Act of Utah, were that such signals must
be audible or visible from at least “500 feet under normal
conditions.” Id. ¶ 13 (cleaned up). While there was no dispute that
the deputy’s lights and siren had been on, the county had
presented “no evidence . . . regarding the distance from which the
signals could be seen or heard.” Id. ¶ 36. The court held that
20250290-CA,
20250291-CA 9 2026 UT App 139
Ayala v. Unified Police Department
because there was no evidence the deputy’s lights and siren
complied with the statute, “a disputed issue of material fact
remain[ed],” rendering summary judgment on the basis of
governmental immunity improper. Id.
¶21 While the requirements of the current version of the statute
differ in some ways from those applicable in Clegg, see supra ¶ 15,
the governing principle from Clegg remains the same. It is not
enough to simply show that an officer’s lights or siren were
activated; to qualify for governmental immunity, a party must
also show that the officer’s lights or siren were adequate under
the governing statute. Clegg, 2010 UT 5, ¶ 14; see also Kouris v. Utah
Highway Patrol, 2003 UT 19, ¶ 14, 70 P.3d 72 (reversing a grant of
summary judgment on governmental immunity grounds where
the statutory adequacy of a highway patrol trooper’s emergency
lights remained a “question[] of material fact yet to be
determined”). Applying Clegg to the present case, we thus
conclude UPD failed to establish its compliance with the visual
signal requirement.
¶22 UPD fares no better on the audible signal alternative. On
this point, UPD claims there is no dispute because Andrus
testified he had activated his patrol vehicle’s siren and Ayala and
Mauger “testified they heard sirens.” Ayala admitted hearing the
first officer’s siren, but both Ayala and Mauger testified they did
not hear Andrus’s siren before the collision. Even the officer who
had been traveling directly in front of Andrus testified he could
not tell if Andrus’s siren was activated because he “couldn’t hear
over [his own] siren.” Viewing the facts in the light most favorable
to Ayala and Mauger, as we must, such testimony creates a
dispute of material fact.
¶23 Yet even if we discount this testimony and assume that
Andrus’s siren was activated, here too UPD made no effort to
establish that Andrus’s siren was of the type required by statute.
20250290-CA,
20250291-CA 10 2026 UT App 139
Ayala v. Unified Police Department
Section 41-6a-1625 of the Utah Code, cited in section 41-6a-212,
requires that “[a]n authorized emergency vehicle shall be
equipped with a siren, whistle, or bell capable of emitting sound
audible under normal conditions from a distance of not less than
500 feet.” Utah Code § 41-6a-1625(4)(a). It further provides that
“[t]he type of sound” used for the siren must be approved by DPS.
Id. § 41-6a-1625(4)(b). At no point did UPD attempt to establish
that Andrus’s siren complied with such requirements.
¶24 As set forth in Clegg, the failure to show that an officer’s
lights or siren was adequate under the governing statute is fatal
to a motion for summary judgment.
B. The Duty to Act as a Reasonably Prudent Emergency
Vehicle Operator Under the Circumstances
¶25 Utah courts “have long recognized that drivers of
emergency vehicles owe a duty of reasonable care to other
motorists on the road.” Clegg v. Wasatch County, 2010 UT 5, ¶ 9,
227 P.3d 1243. In order to qualify for governmental immunity,
“the operator of an authorized emergency vehicle” must “act as a
reasonably prudent emergency vehicle operator under the
circumstances.” Utah Code § 41-6a-212(7)(a). UPD argues there
can be no dispute that “Officer Andrus acted like a reasonably
prudent emergency vehicle operator,” in large part because he
proceeded through the intersection in a similar manner as—and
mere seconds after—the other two officers. 6
6. UPD also contends Andrus acted reasonably because Ayala had
a duty to yield the right-of-way. See Utah Code § 41-6a-904(1)
(instructing drivers to yield the right-of-way to “an authorized
emergency vehicle using audible or visual signals under Section
41-6a-212 or 41-6a-1625”). But because UPD never established that
(continued…)
20250290-CA,
20250291-CA 11 2026 UT App 139
Ayala v. Unified Police Department
¶26 In contrast, Ayala and Mauger contend it was improper for
the district court to conclude that Andrus had acted reasonably as
a matter of law. They first assert that a dispute of material fact
remained regarding whether Andrus had slowed down to the
extent necessary for safe operation of his vehicle considering the
existing traffic conditions. See Utah Code § 41-6a-212(3)(b)
(establishing that an emergency vehicle operator’s privilege of
running a red light is qualified by first “slowing down as may be
necessary for safe operation”). 7 Ayala and Mauger both testified
that a large dump truck impeded their view of any oncoming
southbound traffic on 1300 West. Andrus, too, admitted his view
of eastbound traffic on 7000 South was obstructed by the other
vehicles stopped at the intersection. In light of this undisputed
“blind spot” caused by the afternoon traffic, Ayala and Mauger
argue Andrus should have further reduced his speed before
entering the intersection. Viewing this fact in the light most
favorable to Ayala and Mauger, we agree that whether Andrus
slowed down to the extent necessary given existing traffic
conditions was a material fact that remained in dispute.
¶27 Ayala and Mauger also claim that the UPD Policy Manual
was relevant to assessing Andrus’s reasonableness and that
because Andrus undisputedly “violated several provisions of the
[UPD Policy] Manual, the [district] court erred by concluding, as
a matter of law, that he drove reasonably.” In response, UPD
Andrus’s emergency lights or siren were statutorily adequate, see
supra ¶¶ 21–24, this argument fails.
7. We note that while “slowing down as may be necessary for safe
operation” is a distinct requirement under the statute, see Utah
Code § 41-6a-212(3)(b), whether an emergency vehicle operator
has done so may also go to whether that operator has “act[ed] as
a reasonably prudent emergency vehicle operator under the
circumstances,” id. § 41-6a-212(7)(a).
20250290-CA,
20250291-CA 12 2026 UT App 139
Ayala v. Unified Police Department
insists its internal policies are not relevant to determining whether
Andrus acted reasonably and considering them would “confuse[]
UPD’s internal review standards with the standards for immunity
and negligence.” But UPD is incorrect. When faced with a similar
argument in Clegg, the supreme court held that “violation of the
Policy Manual will be relevant to the question of negligence, but
will not necessarily be determinative.” 2010 UT 5, ¶ 29. Because
the UPD Policy Manual is relevant to evaluating whether Andrus
breached his duty to act reasonably, we agree with Ayala and
Mauger that UPD’s own determination that Andrus violated the
UPD Policy Manual precluded any conclusion that Andrus had
driven reasonably as a matter of law. 8
¶28 For the foregoing reasons, we conclude UPD was not
entitled to judgment as a matter of law that Andrus operated his
8. UPD also asserts the disciplinary report containing UPD’s
findings is wholly inadmissible because it “constitutes a
subsequent remedial measure” under rule 407 of the Utah Rules
of Evidence. The report does include a written warning and
mentions potential “additional discipline.” With respect to these
portions, we are persuaded by UPD’s rule 407 argument. But we
see no reason that the portion of the report describing UPD’s
investigative conclusions—namely, that Andrus violated certain
provisions of the UPD Policy Manual—would also be
inadmissible under this rule. See Packard v. City & County of
Denver, 173 F.4th 1247, 1260 (10th Cir. 2026) (“[P]ost-event
investigative tests or reports are generally not subsequent
remedial measures . . . .”); Bullock v. BNSF Ry. Co., 399 P.3d 148,
158 (Kan. 2017) (“[I]t is not unusual for some evidence to include
information that is permissible, such as investigative conclusions,
and information that is impermissible, such as employee
discipline.”). Those portions of the report meting out the warning
and referencing potential additional discipline could simply be
redacted.

CONCLUSION
¶29 Viewing the facts in a light most favorable to Ayala and
Mauger, we conclude that multiple disputes of material fact
remain regarding the elements of UPD’s governmental immunity
defense and that UPD failed to establish its entitlement to
judgment as a matter of law. The district court thus erred by
granting summary judgment. Accordingly, we reverse and
remand this case for further proceedings.
