OPINION
¶ 1 In this special action, the State of Arizona seeks relief from the rulings of the
Factual and Procedural Background
¶ 2 Oliveri was charged with four counts of aggravated DUI, two of which require the state to prove that he was “impaired to the slightest degree,” and Nelson was charged with two counts of aggravated DUI, one of which requires proof that he was “impaired to the slightest degree.” See A.R.S. § 28-1381(A)(1). In both eases, the respondent judge expressed his intent to instruct the jury using RAJI 28.1383(A)(1)-1 to define the necessary elements of aggravated DUI. The state objected on both occasions, and the respondent judge granted a stay of the trials in both proceedings to allow the state to challenge his ruling by bringing special actions in this court. The state filed its petitions, which we have consolidated.
Special Action Jurisdiction

State ex rel. Romley v. Martin,
Discussion
¶ 4 The state argues that the respondent judge’s intended jury instruction based on RAJI 28.1383(A)(1)-1 is erroneous because it adds an additional element to the charged offenses, requiring it to prove the defendants’ ability to drive was impaired instead of proving only that they had been impaired. We review de novo whether a jury instruction correctly states the law.
State v. Johnson,
¶ 5 Preliminarily, Oliveri and Nelson contend we should review the jury instructions as a whole. But although that would be proper if we were reviewing the propriety of the instruction retrospectively and deciding on appeal whether therе had been error,
see, e.g., State v. Zaragoza,
¶ 6 We first note that the proposed RAJI 28.1383(A)(1)-1, which instructs on aggravated DUI, incorporates the elements of the basic DUI instruction, RAJI 28.1381(A)(1)-1. Compare State Bar of Arizona, Revised Arizona Jury Instructions (Criminal) 28.1381(A)(1)-1 with RAJI 28.1383(A)(1)-1 (3d 2008). The respondent judge made his ruling based on whether RAJI 28.1381(A)(1)-1 correctly states the law in A.R.S. § 28-1381(A)(1). Therefore, we similarly focus our analysis on RAJI 28.1381(A)(1)-1 and § 28-1381(A)(1).
¶ 7 Section 28-1381(A)(l) provides: “It is unlawful for a persоn to drive or be in actual physical control of a vehicle ... [wjhile under the influence of intoxicating liquor ... if the person is impaired to the slightest degree.” The impairment must result from the intoxicating liquor.
See
§ 28-1381(A)(l);
State v. Morales,
¶ 8 “Thе purpose of jury instructions is to inform the jury of the applicable law in understandable terms.”
State v. Noriega,
¶ 9 The legislature has prohibited a person from driving or being in actual physical control of a vehicle while impaired to the slightest degree by intoxicating liquor. See § 28-1381(A)(1). It has not chosen to require any finding that the person’s physical ability to drive was impaired. See id.
¶ 10 We find that the language added to RAJI 28.1381(A)(1)-1 is improper because it could mislead a jury. 1 The jury could interpret it to require proof that the defendant’s physical ability to drive was impaired as opposed to requiring only proof that the “person” was impaired, for example, in judgment. The state need not offer evidence of bad driving to prove that a defendant is guilty of DUI. See § 28-1381(A)(l). Therefоre, the instruction has the potential to confuse or mislead the jury as to the elements of the offense.
¶ 11 Oliveri and Nelson assert that the challengеd instruction does not require the state to prove an additional element because impairment by alcohol is itself evidence that the person’s ability to drive a motor vehicle is impaired. Although we agree the jury could interpret the “ability to drive” language broadly, it could also interpret it nаrrowly and require a physical impairment. And Oliveri and Nelson do not suggest any harm could arise from the jury being given an instruction more accurately stating the lаw.
¶ 12 Oliveri and Nelson next argue that the history of the statute and the accompanying case law support the inclusion of the language regarding the person’s impaired ability to drive. But our duty in interpreting statutes is “to give effect to the legislature’s intent” and when the “statute’s language is plain and unambiguous, we look no further.”
State v. Hinden,
¶ 13 The history of the DUI statute and the RAJI does show, however, that the RAJI did not change significantly in this regard when the statute was amеnded to include the requirement that the person be impaired. Rather it retained the language regarding the ability to drive being impaired in the slightest degree.
¶ 14 Oliveri and Nelson further contend that our supreme court’s decision in
Clayton v. State,
Conclusion
¶ 15 This opinion has limited effect. We are not examining or changing thе substantive law concerning driving while intoxicated. And, although the RAJI instruction has remained essentially unchanged without this issue having been addressed, courts and parties apparently have been able to explain the law correctly to the juries. Nevertheless, it is important that jury instructions conform accurately to the elements of the relevant statute. Therefore, we accept jurisdiction of the state’s petitions and grant relief, directing the resрondent not to give the RAJI instruction as written.
Notes
. We are not convinced, however, by the state’s assertion that
