LORELLO, Judge
       Kaira Noelle Southworth appeals from her judgment of conviction for felony driving
under the influence (DUI). Southworth argues that the district court erred in denying her motion
to suppress. For the reasons set forth below, we affirm.
                                                I.
                     FACTUAL AND PROCEDURAL BACKGROUND
        An officer initiated a traffic stop of a vehicle driven by Southworth because the officer
believed Southworth made an illegal lane change and because her muffler was excessively noisy.
After speaking with Southworth, the officer suspected Southworth was driving under the
influence of alcohol. As a result, the officer had Southworth perform field sobriety tests and
ultimately arrested her for DUI.

                                                1
       The State charged Southworth with felony DUI.            I.C. §§ 18-8004 and 18-8005(6).
Southworth filed a motion to suppress, arguing that the officer lacked reasonable suspicion to
initiate the traffic stop.   The district court denied the motion, concluding the officer had
reasonable suspicion Southworth violated traffic laws governing muffler noise and lane changes.
Subsequently, Southworth entered a conditional guilty plea to DUI, reserving her right to appeal
the denial of her motion to suppress.
                                                II.
                                   STANDARD OF REVIEW
       The standard of review of a suppression motion is bifurcated. When a decision on a
motion to suppress is challenged, we accept the trial court’s findings of fact that are supported by
substantial evidence, but we freely review the application of constitutional principles to the facts
as found. State v. Atkinson, 128 Idaho 559, 561, 916 P.2d 1284, 1286 (Ct. App. 1996). At a
suppression hearing, the power to assess the credibility of witnesses, resolve factual conflicts,
weigh evidence, and draw factual inferences is vested in the trial court. State v. Valdez-Molina,
127 Idaho 102, 106, 897 P.2d 993, 997 (1995); State v. Schevers, 132 Idaho 786, 789, 979 P.2d
659, 662 (Ct. App. 1999).
                                                III.
                                           ANALYSIS
       Southworth argues that the district court erred in denying her motion to suppress because
the officer lacked reasonable suspicion to conduct a traffic stop.       Specifically, Southworth
contends that the lane change the officer observed was lawful and that the officer lacked specific,
articulable facts that the muffler on Southworth’s vehicle constituted an equipment violation.
The State responds that the district court correctly concluded the officer had reasonable suspicion
to stop Southworth for an illegal lane change and an equipment violation. We hold that there
was reasonable suspicion to stop Southworth for a violation of Idaho’s muffler noise statute,
I.C. § 49-937.
       A traffic stop by an officer constitutes a seizure of the vehicle’s occupants and implicates
the Fourth Amendment’s prohibition against unreasonable searches and seizures. Delaware v.
Prouse, 440 U.S. 648, 653 (1979); Atkinson, 128 Idaho at 561, 916 P.2d at 1286. Under the
Fourth Amendment, an officer may stop a vehicle to investigate possible criminal behavior if

                                                 2
there is a reasonable and articulable suspicion that the vehicle is being driven contrary to traffic
laws. United States v. Cortez, 449 U.S. 411, 417 (1981); State v. Flowers, 131 Idaho 205, 208,
953 P.2d 645, 648 (Ct. App. 1998). The reasonableness of the suspicion must be evaluated upon
the totality of the circumstances at the time of the stop. State v. Ferreira, 133 Idaho 474, 483,
988 P.2d 700, 709 (Ct. App. 1999). The reasonable suspicion standard requires less than
probable cause but more than mere speculation or instinct on the part of the officer. Id. An
officer may draw reasonable inferences from the facts in his or her possession, and those
inferences may be drawn from the officer’s experience and law enforcement training. State v.
Montague, 114 Idaho 319, 321, 756 P.2d 1083, 1085 (Ct. App. 1988).
       During the suppression hearing, the officer testified that he was familiar with the model
of vehicle Southworth was driving and that her vehicle was “clearly louder than . . . most of if
not a high percentage of” vehicles of the same or similar model.            When asked whether
Southworth’s vehicle sounded “much louder” than other vehicles of the same model, the officer
testified that Southworth’s vehicle was “definitely louder.” Based upon this unrefuted testimony,
the district court found the officer was justified in stopping Southworth for a violation of
I.C. § 49-937. On appeal, Southworth contends that the officer’s auditory perceptions in this
case were insufficient to support reasonable suspicion. Our prior decision in State v. Meyer, 158
Idaho 953, 956, 354 P.3d 515, 518 (Ct. App. 2015) governs our analysis of this contention.
       Like Southworth, the defendant in Meyer was subject to a traffic stop due to “a loud
exhaust” in violation of I.C. § 49-937. Meyer, 158 Idaho at 954, 354 P.3d at 516. In addressing
Meyer’s argument that the officer lacked reasonable suspicion that her car’s exhaust was too
loud or that her car’s muffler was defective, this Court stated:
               Here, the district court credited the deputy’s testimony that the deputy
       identified Meyer’s car as making a louder-than-normal exhaust noise when the
       vehicle was 200 feet away from the deputy. Specifically, the deputy recalled that
       a normal car would produce a sound of two or three points on a ten-point scale,
       whereas Meyer’s car was producing a sound of five or six points on the same
       scale. Taken together, these facts give rise to a particularized and objective basis
       for suspecting that the white Pontiac, driven by Meyer, was in violation of
       I.C. § 49-937(1), and thus the deputy acquired reasonable suspicion to stop the
       car.
Meyer, 158 Idaho at 955, 354 P.3d at 517.

                                                  3
       This Court also rejected Meyers’ argument that the deputy should have provided expert
testimony about the muffler or the sound it emitted or evidence of what a device measured the
sound level of Meyer’s vehicle’s exhaust to be. Id. In doing so, the Court emphasized that the
question was not whether the facts articulated by the officer in support of the traffic stop were
sufficient to prove a violation of I.C. § 49-937 beyond a reasonable doubt. Rather, the question
was whether there was reasonable suspicion to support a traffic stop. The Court held that an
officer’s auditory perception of a loud muffler gives rise to reasonable suspicion. Meyer, 158
Idaho at 956, 354 P.3d at 518.
       As in Meyer, the officer’s auditory perception that Southworth was operating a vehicle
with a loud muffler was sufficient to provide reasonable suspicion to conduct a traffic stop. In
this case, the district court credited the officer’s testimony that he heard the muffler noise from
Southworth’s vehicle while stopped just behind it in the neighboring traffic lane. Based upon his
past experience, the officer believed Southworth’s vehicle was “clearly” louder than similar
vehicles. These facts, considered in light of the totality of the circumstances, were sufficient to
support a reasonable suspicion of a violation of I.C. § 49-937.
       We are unpersuaded by Southworth’s argument that the principle from Meyer, that an
officer’s auditory perception provides reasonable suspicion, does not apply to the facts of
Southworth’s case. Southworth’s argument in this regard is premised on the facts from Meyer
that the officer heard the loud muffler from 200 feet away and rated how loud the muffler was
using a point scale. Conversely, Southworth argues, the officer in this case was “just one lane
over” when he noticed the muffler noise, did not say “how much louder” the vehicle was, and
did not know the decibel level that would violate the statute. However, the reasonable suspicion
principle stated in Meyer was not dependent on the numerical values assigned to the officer’s
distance from the vehicle or on the use of a descriptive point scale regarding volume.
Accordingly, the factual distinctions between this case and Meyer are inconsequential.
       The facts found by the district court, considered in light of the totality of the
circumstances, support a reasonable suspicion that Southworth violated I.C. § 49-937.

                                                 4
Therefore, the officer lawfully conducted a traffic stop of Southworth’s vehicle. Southworth has
failed to show the district court erred in denying her motion to suppress. 1

                                         CONCLUSION
       The district court correctly concluded that law enforcement had reasonable suspicion to
stop the vehicle Southworth was driving. Thus, Southworth has failed to show that the district
court erred in denying her motion to suppress.           Accordingly, Southworth’s judgment of
conviction for felony DUI is affirmed.

       Because we affirm the district court’s denial of Southworth’s motion to suppress based
upon reasonable suspicion of a violation of I.C. § 49-937, it is unnecessary for us to consider
whether Southworth violated any traffic laws governing lane changes. See State v. Goodwin,
131 Idaho 364, 366, 956 P.2d 1311, 1313 (Ct. App. 1998) (observing that a lower court ruling
supported by two independent, alternative grounds can be affirmed on either ground).
