MASSA, Justice.
As the two companion appeals we resolve today vividly illustrate, sometimes standards of review decide cases.1 In the instant case, the trial court found law enforcement had reasonable suspicion to conduct a traffic stop and admitted the resulting evidence; in State v. Keek, No. 67S01-1403-CR-179, 4 N.E.3d 1180, 2014 WL 1226230 (Ind. Mar.25, 2014), the trial court reached the opposite conclusion. We affirm both trial courts and decline appel[364]*364lants’ invitation to invade the fact-finder’s province.
Facts and Procedural History
Around 1:00 a.m. on October 15, 2011, Deputy Casey Claeys of the Elkhart County Sheriffs Department was following another vehicle down County Road 4. Deputy Claeys later testified he saw the vehicle “drive off the right side, which was the south side of the road, twice.” Tr. at 24. Immediately after the second incident, he turned on his vehicle camera and initiated a traffic stop for “unsafe lane movement.” Tr. at 24. The camera, once activated, retroactively records the previous thirty seconds.
Deputy Claeys later testified that when he approached the vehicle, he noticed the driver, Joanna S. Robinson, “had glossy, blood shot eyes, slurred speech ... and the odor of an alcoholic beverage coming from her breath.” Tr. at 26. Upon questioning, Robinson admitted she had drunk one beer, and Deputy Claeys proceeded to conduct standard field sobriety tests on her. After she failed three of the tests, Robinson told Deputy Claeys she had marijuana concealed in her clothing; she then removed the marijuana and dropped it onto the ground. At that point, Deputy Claeys took Robinson into custody and transported her to the Elkhart County Jail, where a chemical test showed her blood-alcohol level was 0.09.
The Elkhart County Prosecutor charged Robinson with three Class A misdemeanors (operating a motor vehicle with a suspended license,2 possession of marijuana,3 and operating a vehicle while intoxicated4) and one Class C misdemeanor (operating with a breath-alcohol level over 0.085). By counsel, Robinson moved to suppress all the evidence against her, arguing Deputy Claeys did not have reasonable suspicion to justify the stop because Robinson “never left her lane of traffic in any form.” App. at 23. Pursuant to the parties’ agreement, the trial court considered Robinson’s motion in conjunction with the evidence presented at her bench trial, which included Deputy Claeys’s testimony, blood and breath test evidence, and the video from the camera on Deputy Claeys’s vehicle. The trial court also heard final argument from both parties; the State encouraged the court to credit Deputy Claeys’s testimony over the videotape, while the defendant urged the opposite.
Ultimately, the trial court denied Robinson’s motion to suppress. Citing State v. McCaa, 968 N.E.2d 24, 31 (Ind.Ct.App. 2012) (finding reasonable suspicion for a traffic stop when the defendant drove “slowly and off of the roadway twice”), the trial court stated it “reviewed the video on approximately ten occasions and cannot conclude from the video that the defendant’s vehicle actually left the roadway ... but it does show the vehicle veering on two occasions onto the white fog line.” App. at 33. The trial court noted, however, that it was “quite possible that the officer’s actual visual observation of the defendant’s vehicle was superior to the video camera in his car.” App. at 33. After considering all of this evidence, the trial court concluded this case was “perhaps a closer call” than McCaa, but that “the act of weaving onto the fog line, while not itself an illegal act, did give a trained police officer justification to stop and inquire further as to the driver’s condition.” App. at 33, 34. The trial court then found Robinson guilty of [365]*365possession of marijuana, operating while intoxicated, and operating with a breath-alcohol level over 0.08. It merged the latter two convictions and sentenced her to one year of imprisonment for each conviction, to run concurrently and suspended to probation.
Robinson appealed, arguing the trial court wrongly denied her motion to suppress. A panel of our Court of Appeals agreed and reversed her conviction. Robinson v. State, 985 N.E.2d 1141,1148 (Ind. Ct.App.2013).
We granted transfer, thereby vacating the opinion below. Robinson v. State, 990 N.E.2d 945 (Ind.2013) (table); Ind. Appellate Rule 58(A).
Standard of Review
Our justice system entrusts the admission of evidence to the trial court’s sound discretion. Schmitt v. State, 730 N.E.2d 147, 148 (Ind.2000). We review a trial court’s denial of a defendant’s motion to suppress deferentially, construing conflicting evidence in the light most favorable to the ruling, but we will also consider any substantial and uncontested evidence favorable to the defendant. Holder v. State, 847 N.E.2d 930, 935 (Ind.2006) (citing Murphy v. State, 747 N.E.2d 557, 559 (Ind.2001); Ogle v. State, 698 N.E.2d 1146, 1148-49 (Ind.1998)). We defer to the trial court’s findings of fact unless they are clearly erroneous, and we will not reweigh the evidence. Campos v. State, 885 N.E.2d 590, 596 (Ind.2008) (citing State v. Quirk, 842 N.E.2d 334, 340 (Ind.2006)). When the trial court’s denial of a defendant’s motion to suppress concerns the constitutionality of a search or seizure, however, it presents a question of law, and we address that question de novo. Id. (citing Myers v. State, 839 N.E.2d 1146, 1150 (Ind.2005)).
The Trial Court Correctly Denied Robinson’s Motion to Suppress
Robinson argues Deputy Claeys lacked reasonable suspicion to stop her vehicle and thus violated her rights under both the federal and state constitutions.6 As a threshold matter, both parties dispute the significance of the video evidence. Robinson notes the trial court conceded the video “did not clearly demonstrate that Robinson’s vehicle veered off the roadway ... but speculated that the officer’s observations at the scene were superior to his in-car camera.” Appellant’s Br. at 2. The State, on the other hand, cautions us not to “rest [our] determination on minutia of an imperfect and rudimentary video.” Appel-lee’s Br. at 8.
While technology marches on, the appellate standard of review remains constant. As we said above, we do not reweigh the evidence. Our colleagues in other states have taken a similar approach when faced with video evidence. State v. Vanscoyk, No. A-12-024, 2012 WL 6580786 at *6 [366]*366(Neb.Ct.App. Dec. 18, 2012) (“Vanscoyk essentially asks us to reweigh evidence and witness credibility to determine whether Officer Kowalewski’s testimony is credible in light of the video. This is not the appropriate province of an appellate court.”); State v. Gross, No. 107320, 2012 WL 3136809 at *4 (Kan.Ct.App.

While technology marches on, the appellate standard of review remains constant. As we said above, we do not reweigh the evidence. Our colleagues in other states have taken a similar approach when faced with video evidence. State v. Vanscoyk, No. A-12-024, 2012 WL 6580786 at *6 [366]*366(Neb.Ct.App. Dec. 18, 2012) (“Vanscoyk essentially asks us to reweigh evidence and witness credibility to determine whether Officer Kowalewski’s testimony is credible in light of the video. This is not the appropriate province of an appellate court.”); State v. Gross, No. 107320, 2012 WL 3136809 at *4 (Kan.Ct.App. July 27, 2012) (“We do not reweigh the evidence, and the district court’s conclusion that the video was ‘the clearest evidence’ is not contrary to any uncontested testimony.”); State v. White, No. E2010-02238-CCA-R3CD, 2011 WL 5335471 (Tenn.Crim.App. Nov. 2, 2011) (declining, in a challenge to the sufficiency of the evidence for a conviction for drunk driving, to reweigh the evidence and find a video recording more reliable than eyewitness testimony).7
We do not believe, however, as some of our colleagues in other jurisdictions do, that the very act of reviewing video evidence constitutes impermissible appellate reweighing. State v. Rascon, No. 30,561, 2011 WL 704472 at *2 (N.M.Ct. App. Jan. 14, 2011) cert. denied, 2011-NMCERT-003, 150 N.M. 619, 264 P.3d 520 (2011) (table) (declining even to review a video of a traffic stop in a reasonable suspicion case on the ground that doing so would amount to reweighing the evidence). Rather, we consider video evidence admitted in the trial court to be a necessary part of the record on appeal, just like any other type of evidence. But see Nava v. Kan. Dep’t of Revenue, 281 P.3d 597 (Kan.Ct.App.2012) (table), 2012 WL 3135902 at *4 (“the Department asks us to reweigh not only the witness[es]’ testimony but also the district court’s factual determination regarding the video evidence without having even included a copy of the video in the record on appeal.”).
And just like any other type of evidence, video is subject to conflicting interpretations. In Scott v. Harris, 550 U.S. 372, 127 S.Ct. 1769, 167 L.Ed.2d 686 (2007), Justice Scalia, writing for the majority of the Court, described a videotape as showing “a Hollywood-style car chase of the most frightening sort, placing police officers and innocent bystanders alike at great risk of serious injury.” Id. at 380, 127 S.Ct. 1769. Based largely on his impression of that video, he concluded police were justified in using deadly force to end the pursuit. Id. at 386, 127 S.Ct. 1769. Justice Stevens, dissenting, described the very same video as “hardly the stuff of Hollywood” and opined it did not show “any incidents that could even be remotely characterized as ‘close calls.’ ” Id. at 392, 127 S.Ct. 1769 (Stevens, J., dissenting).
What is more, “the video record may ‘speak for itself,’ but it does not and cannot speak for the visual input a judge observes and interprets that falls outside the scope of the camera, nor does it filter events and behavior through his or her experience and expertise.” Bernadette Mary Donovan, Note, Deference in A Digital Age: The Video Record and Appellate Review, 96 Va. L. Rev. 643, 676 (2010). Although this statement was made in the context of a discussion of appellate consideration of video trial transcripts, we believe the same reasoning applies to appellate consideration of video evidence, and even to law [367]*367enforcement reaction to an evolving situation. Deputy Claeys, as he drove down County Road 4 on that October night, was observing Robinson’s vehicle through the lens of his experience and expertise. And when Deputy Claeys testified at the suppression hearing, the trial judge heard his testimony — along with the other witness testimony and evidence, including the video — through the lens of Ms experience and expertise. Ultimately, that experience and expertise led the trial judge to weigh Deputy Claeys’s testimony more heavily than the video evidence, and we decline Robinson’s invitation to substitute our own judgment for that of the trial court and reba-lance the scales in her favor.
The trial court found, as a matter of fact, that to the extent Deputy Claeys’s testimony conflicted with the video, the former was more reliable than the latter.8 Deputy Claeys testified “both passenger side tires were over the fog line” and “completely off the roadway” “twice.” Tr. at 48, 24. Thus, we must now decide whether those facts constitute reasonable suspicion for a traffic stop, as a matter of law, in accordance with our federal and state constitutions.
I. The Fourth Amendment
The Fourth Amendment provides protection against unreasonable searches and seizures by generally prohibiting such acts without a warrant supported by probable cause. U.S. Const, amend. IV; Clark v. State, 994 N.E.2d 252, 260 (Ind.2013). The Terry stop, perhaps the most popular exception to this rule, permits an officer to “stop and briefly detain a person for investigative purposes if the officer has a reasonable suspicion supported by articulable facts that criminal activity ‘may be afoot,’ even if the officer lacks probable cause.” United States v. Sokolow, 490 U.S. 1, 7, 109 S.Ct. 1581, 104 L.Ed.2d 1 (1989) (quoting Terry v. Ohio, 392 U.S. 1, 30, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968)). Such a stop “must be justified by some objective manifestation that the person stopped is, or is about to be, engaged in criminal activity.” Armfield v. State, 918 N.E.2d 316, 319 (Ind.2009) (quoting United States v. Cortez, 449 U.S. 411, 417, 101 S.Ct. 690, 66 L.Ed.2d 621 (1981)).
Both Robinson and the State rely heavily on Barrett v. State, 837 N.E.2d 1022 (Ind.Ct.App.2005), in which police received a tip that two persons driving a blue Chevrolet Geo Tracker had purchased methamphetamine ingredients at a Meijer store. Id. at 1024. Officers located that vehicle in the store parking lot and followed it out onto the interstate, where they observed it drift to the right and travel on the fog line for about forty yards. Id. at 1025. A divided panel of our Court of Appeals found reasonable suspicion to support the stop. Id. at 1028. Robinson argues Barrett was wrongly decided and urges us to adopt the reasoning Judge Mathias expressed in his dissent. Id. at 1031 (Mathias, J., dissenting) (suggesting that if simply drifting in a lane of traffic provided [368]*368probable cause for a stop, the reasonable suspicion standard would be so low as to be almost meaningless). In the alternative, Robinson argues this case is distinguishable from Barrett. The State, on the other hand, asserts Barrett and other cases have established that an officer who observes a vehicle drive onto the fog line multiple times has reasonable suspicion to stop that vehicle on the ground that the driver is likely impaired. McCaa, 963 N.E.2d at 31 (finding reasonable suspicion to conduct a traffic stop when the officer had received several reports that a semi was driving erratically and observed the semi travel under the speed limit and cross the fog line twice); Jaremczuk v. State, 177 Ind.App. 628, 629-31, 380 N.E.2d 615, 616-17 (1978) (finding reasonable suspicion to conduct a traffic stop when officers received a tip that a particular vehicle was involved in a hit-and-run and then observed a vehicle matching that description cross the fog line).
Robinson is correct, of course, that unlike in Barrett and McCaa, there was no “tip” in this case to corroborate Deputy Claeys’s observation that her driving appeared erratic. Even so, we do not believe the Fourth Amendment requires police “to grant drunk drivers ‘one free swerve’ before they can legally be pulled over.” Virginia v. Harris, 558 U.S. 978, 130 S.Ct. 10, 12, 175 L.Ed.2d 322 (2009) (Roberts, C.J., dissenting from denial of certiorari). Even if it did, Robinson swerved twice on a relatively straight, flat roadway. Although such movement could have been attributable to driver distraction or some other more innocuous cause, Terry does not require absolute certainty of illegal activity, but rather reasonable suspicion. On these facts, we find that standard was satisfied.
II. Indiana Constitution Article 1, § 11
Although its text mirrors the federal Fourth Amendment, we interpret Article 1, § 11 of our Indiana Constitution separately and independently. State v. Washington, 898 N.E.2d 1200, 1205-06 (Ind.2008). When a defendant raises a Section 11 claim, the State must show the police conduct “was reasonable under the totality of the circumstances.” Id. We consider three factors when evaluating reasonableness: “1) the degree of concern, suspicion, or knowledge that a violation has occurred, 2) the degree of intrusion the method of the search or seizure imposes on the citizen’s ordinary activities, and 3) the extent of law enforcement needs.” Litchfield v. State, 824 N.E.2d 356, 361 (Ind.2005).
Deputy Claeys witnessed Robinson drive over the fog line twice in a relatively short period of time, giving rise to a reasonable suspicion that she was impaired. The initial intrusion — a Terry stop — was relatively minor, and Deputy Claeys only escalated the stop after he noticed several signs that Robinson was in fact intoxicated. And few Hoosiers would dispute the heartbreaking effects of drunk driving in our state. Since 2008, Indiana has seen a 10% annual increase in the number of victims of alcohol-impaired driving accidents. Samuel Nunn, Traffic Safety Facts: Alcohol 2012, 13-C08 Ind. U. Center Crim. Just. Res. 1, 1 (June 2013), available at http:// www.in.gov/cji/files/T_Alcohol.pdf Last year, 158 Hoosiers lost their lives in crashes involving alcohol-impaired drivers. Id. Law enforcement has a strong interest in preventing these accidents, and “police should have every legitimate tool at their disposal for getting drunk drivers off the road.” Harris, 558 U.S. at 978, 130 S.Ct. 10 (Roberts, C.J., dissenting from denial of certiorari). Thus, under the totality of the circumstances, we find Deputy Claeys’s conduct was reasonable and the stop did not offend Article 1, § 11 of our Indiana Constitution.
[369]*369Conclusion
We therefore affirm the trial court’s denial of Robinson’s motion to suppress.
