IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA
SECOND APPELLATE DISTRICT
DIVISION SIX
THE PEOPLE, 2d Crim. No. B255130
(Super. Ct. No. 2011042355)
Plaintiff and Respondent, (Ventura County)
v.
HEATHER ELIZABETH PIAR,
Defendant and Appellant.
Heather Elizabeth Piar appeals from the judgment entered after she pled
guilty to possession of a controlled substance (Health & Saf. Code, § 11377, subd. (a)).
The trial court reduced the offense to a misdemeanor pursuant to Penal Code section 17,
subdivision (b), suspended the imposition of sentence, and placed appellant on three
years' formal probation with terms and conditions (Pen. Code, § 1210.1). Appellant
contends the court erred in denying her motion to suppress under Penal Code section
1538.5. We affirm.
FACTUAL AND PROCEDURAL BACKGROUND1
Shortly after noon on December 2, 2011, Simi Valley Police Officer Shawn
Throckmorton and his partner were on patrol. Throckmorton had more than six years of
law enforcement experience. Throckmorton was driving on Los Angeles Avenue near
1 The cited facts were presented at the preliminary hearing.
Tapo Canyon when the sound of a very loud muffler drew his attention to a black
Hyundai Tiburon. The Tiburon had just turned from Darrah onto Los Angeles Avenue.
The noise could be heard from two or three hundred feet away.2 Throckmorton also
noticed that the Tiburon's muffler was larger and rounder than an ordinary muffler, and
appeared to be an after-market part. He suspected the driver was operating the Tiburon
with an exhaust system that had been modified to produce excessive engine noise, in
violation of Vehicle Code section 27151, subdivision (a).3
Throckmorton followed the Tiburon and ran its license plate. He learned
that its registered owner, appellant, was on probation and subject to search conditions.4
He stopped the Tiburon and asked the driver for her name and her driver's license. When
asked, appellant admitted she was on probation. Throckmorton searched the Tiburon and
2 The record contains inconsistent references regarding the distance from which
the Tiburon could be heard. Throckmorton testified it "was so loud that you could hear it
from probably two to three feet away." The court stated, "[h]e said . . . it could be heard
from two to three feet away." Appellant's counsel concurred, but also repeatedly argued
that Throckmorton made a "conclusionary statement . . . that he could hear it two to three
hundred feet away." Although the record does not disclose the distance between Darrah
and Tapo Canyon, we have taken judicial notice of the official street map of the City of
Simi Valley. In accordance with Evidence Code section 459, subdivisions (c) and (d),
the parties have been given notice and an opportunity to be heard on the issue of judicial
notice of the map. (Planned Parenthood Shasta-Diablo, Inc. v. Williams (1995) 10
Cal.4th 1009, 1021, fn. 2.) Darrah intersects with Los Angeles Avenue 0.3 miles from its
intersection with Tapo Canyon.
3 All further statutory references are to the Vehicle Code unless otherwise stated.
4 The parties stipulated that appellant was on probation, with various terms and
conditions, including her agreement to "consent to a search of [her] person, vehicle, . . .
or any other personal or real property under [her] control for controlled substances . . .
and related paraphernalia[] by a peace officer . . . at any time, with or without a search
warrant, warrant of arrest, or reasonable cause."

found a glass pipe used for smoking methamphetamine. A female officer searched
appellant and recovered a baggie that contained methamphetamine from her clothing.
At the preliminary hearing and the ensuing motions to suppress and dismiss
the information (Pen. Code, §§ 1538.5 & 995), appellant moved to suppress the
methamphetamine and the glass pipe contending that she had been unlawfully detained.
All motions were denied.
DISCUSSION
Appellant contends that her traffic stop violated the Fourth Amendment
because the officer lacked a reasonable suspicion that she was violating the law. We
disagree.
In reviewing the denial of a suppression motion, we must resolve all factual
conflicts in the manner most favorable to the trial court's ruling. (People v. Lomax (2010)
49 Cal.4th 530, 563.) We defer to the court's express and implied findings if supported
by substantial evidence, yet exercise our independent judgment in determining whether
the challenged search or seizure is lawful based on those facts. (Ibid.; People v. Woods
(1999) 21 Cal.4th 668, 673-674.)
A detention is reasonable and thus lawful "'. . . when the detaining officer
can point to specific articulable facts that, considered in light of the totality of the
circumstances, provide some objective manifestation that the person detained may be
involved in criminal activity.' [Citation.]" (People v. Hernandez (2008) 45 Cal.4th 295,
299.) An officer may stop a motorist if the stop is based on a reasonable suspicion that
the driver has violated the Vehicle Code. (People v. Bennett (2011) 197 Cal.App.4th
907, 912-913.)
In denying the suppression motion, the preliminary hearing magistrate
necessarily concluded that Throckmorton had reasonably suspected that appellant was
violating section 27151, subdivision (a), which prohibits modification of "the exhaust
3
system of a motor vehicle in a manner which will amplify or increase the noise emitted
by the motor of the vehicle so that [it] is not in compliance with [statutory noise limits]."
(Ibid.) It further provides that "No person shall operate a motor vehicle with an exhaust
system so modified." (Ibid.)
Throckmorton articulated facts sufficient to support a reasonable suspicion
that appellant was driving a car with an exhaust system that had been modified to exceed
statutory noise limits, in violation of section 27151. He heard the Tiburon before he saw
it. He observed that its muffler was larger and rounder than an ordinary muffler. (People
v. Valencia (1993) 20 Cal.App.4th 906, 909, 912-913 [officer lawfully stopped a vehicle
for suspicion of violating section 27150 after hearing its "loud exhaust"].)5
We also reject appellant's claim that her detention and the ensuing searches
violated the Fourth Amendment. Officer Throckmorton testified he conducted the search
because he knew that appellant was on probation, a fact he had learned prior to the
detention. (People v. Medina (2007) 158 Cal.App.4th 1571, 1575-1576.) "Warrantless
searches are justified in the probation context because they aid in deterring further
offenses by the probationer and in monitoring compliance with the terms of probation.
[Citations.]" (People v. Robles (2000) 23 Cal.4th 789, 795.) A police officer may search
a probationer with a search condition without any reasonable suspicion of criminal
activity, so long as the search is not undertaken for harassment or for arbitrary or
capricious reasons or in an unreasonable manner. (Medina, supra, at pp. 1575-1576.)
Before Throckmorton stopped the Tiburon, he knew appellant was on probation with a

adequate muffler in constant operation and properly maintained to prevent any excessive
or unusual noise . . . ." (§ 27150, subd. (a).)

search condition. (Ibid.) The motion to suppress was properly denied.

The judgment is affirmed.
