Opinion

Chief Justice BERCH,

opinion of the Court.

¶ 1 This case addresses (a) whether partition ratio evidence is admissible in a prosecution for driving while impaired in violation of A.R.S. § 28-1381(A)(l) if the state elects to introduce breath test results only to prove that the defendant had “an alcohol concentration of 0.08 or more within two hours of driving” in violation of AR.S. § 28-1381(A)(2), and (b) whether evidence relating to the variability of partition ratios in the general population is relevant to a particular defendant’s state of impairment. We conclude that such evidence is relevant and therefore may be admissible to show the defendant’s lack of impairment.

*349 I. BACKGROUND

¶ 2 The State charged Joseph Cooperman with two counts of driving under the influence (“DUI”). The first charge was for driving while “impaired to the slightest degree” by alcohol or other substances, in violation of A.R.S. § 28-1381(A)(l) (the (A)(1) or “impairment” charge). The second charge, filed under § 28-1381(A)(2) (the (A)(2) or “per se” charge), was for having “an alcohol concentration [in the breath or blood] of 0.08 or more within two hours of driving or being in actual physical control of the vehicle.” See A.R.S. § 28-101(2) (defining alcohol concentration). The (A)(2) charge is proven by presenting evidence of the defendant’s breath or blood alcohol concentration (“AC”) and establishing that the test sample was taken within two hours of the time the defendant drove or controlled a vehicle.

¶ 3 Section 28-1381(G) creates statutory presumptions that a person whose breath or blood AC is 0.05 or less “was not under the influence of intoxicating liquor,” (G)(1), and that one whose AC is 0.08 or greater was under the influence, (G)(3). If the AC falls between 0.05 and 0.08, no presumption of intoxication arises, but the AC “may be considered with other competent evidence in determining the guilt or innocence of the defendant.” Id. § 28-1381(G)(2).

¶ 4 Before trial, the State moved in limine to prevent Cooperman from introducing evidence of the variability of the “partition ratio” used to convert breath AC (“BrAC”) to blood AC readings. 1 The State argued that it would not introduce the breath test results to prove under (A)(1) that Cooperman was driving while impaired, although it would present the results in the same trial to prove the per se violation under (A)(2). That is, the State would introduce the breath test reading to prove that Cooperman had an alcohol concentration exceeding 0.08 within two hours of driving, but not to show that Cooperman was driving while impaired. The State maintained that because it did not intend to introduce Cooperman’s breath test results to show impairment, it would not invoke the presumptions set forth in § 28-1381(G). It therefore argued that Cooper-man could not present evidence regarding partition ratios to cast doubt on his state of impairment.

¶ 5 At a hearing before the municipal court, the State and Cooperman presented expert testimony regarding factors affecting the partition ratio. Although the State did not intend to introduce the BrAC results to prove impairment, Cooperman sought to introduce the BrAC and partition ratio evidence to show lack of impairment. The court found that partition ratio evidence is relevant whenever breath test results are introduced in connection with an (A)(1) charge. The court also rejected the State’s argument that such evidence should be excluded under Arizona Rule of Evidence 403. The superior court accepted special action jurisdiction and denied relief, and the court of appeals affirmed. State v. Cooperman, 230 Ariz. 245, 248, 252-53 ¶¶ 5, 25, 282 P.3d 446, 449, 453-54 (App.2012).

¶ 6 We granted the State’s petition for review because this case presents a recurring issue of statewide importance. We have jurisdiction pursuant to Article 6, Section 5(3) of the Arizona Constitution and A.R.S. § 12-120.24.

II. DISCUSSION

¶ 7 Relevant evidence is admissible at trial unless a statute, a constitutional provision, or another rule provides otherwise. Ariz. R. Evid. 402. “We review a trial court’s determination of relevance and admissibility of evidence for an abuse of discretion.” State v. Hardy, 230 Ariz. 281, 291 ¶ 49, 283 P.3d 12, 22 (2012).

A. Relevance

¶8 Evidence is relevant if it has “any tendency to make a fact” that is “of consequence” in the action “more or less probable.” Ariz. R. Evid. 401. In a prosecution for driving under the influence of alcohol in violation of A.R.S. § 28-1381(A)(l), the state must prove that the defendant’s ability to *350 drive or control a vehicle was “impaired to the slightest degree” by consumption of alcohol. That makes evidence regarding impairment relevant.

¶ 9 Arizona statutes and case law recognize a strong correlation between breath and blood alcohol concentration and intoxication. See, e.g., id. § 28-1381(G); State v. Childress, 78 Ariz. 1, 6, 274 P.2d 333, 336 (1954) (“Sobriety of an individual decreases as the percentage of alcohol in his blood increases.”). As noted in Guthrie v. Jones, “[a]lcohol in the breath does not cause impairment; impairment results when alcohol enters the body, is absorbed into the bloodstream, and is transported to the central nervous system and the brain.” 202 Ariz. 273, 274 ¶ 5, 43 P.3d 601, 602 (App. 2002). Thus, blood AC evidence is relevant to show impairment or lack thereof.

¶ 10 The State relies on Guthrie to argue that partition ratio evidence is irrelevant and therefore inadmissible if the prosecutor elects not to invoke the presumption of impairment in § 28-1381(G)(3). See 202 Ariz. at 276 ¶ 13, 43 P.3d at 604. We agree with the court in Guthrie that partition ratio evidence “is not relevant to a prosecution for per se DUI” under (A)(2) because that charge turns solely on alcohol concentration, measured by breath or blood alcohol readings. Id. at 274 ¶ 2, 43 P.3d at 602. The only questions in a per se ease are whether the breath or blood AC is 0.08 or more and whether the reading was obtained within two hours of driving; whether the defendant was impaired is not at issue. AR.S. § 28-1381(A)(2). The court in Guthrie
