OPINION
¶ 1 Appellant Tyla Poshka was convicted after a jury trial of one count of aggravated driving under the influence of alcohol (DUI) with a suspended or revoked driver’s license and one count of aggravated driving with a blood alcohol concentration (BAC) of .08 or more with a suspended or revoked driver’s license. The trial court suspended the imposition of sentence and imposed concurrent, five-year terms of probation. Poshka contends the legislature’s amendment to A.R.S. § 28-1381 is unconstitutionally vague and overbroad and violates her due process rights. Finding no constitutional infirmity to the statute, we affirm.
Factual and Procedural History
¶2 We view the facts in the light most favorable to sustaining the jury verdicts and resolve all reasonable inferences against the appellant.
See State v. Riley,
Constitutionality of A.R.S. § 28-1381
¶3 Poshka challenges the constitutionality of the statute under which she was convicted, § 28-1381, on the grounds that it is both vague and overbroad. We review
de novo
the constitutionality of a statute,
State v. McMahon,
*220 Vagueness
¶ 4 Poshka first argues the statute fails to provide adequate notice of the conduct it prohibits and permits arbitrary and discriminatory enforcement, making the law unconstitutionally vague. Both arguments are grounded in the statute’s alleged deficiency whereby, Poshka maintains, a person of ordinary intelligence is unable to know the precise moment when his or her BAC has reached the prohibited level of .08, because various factors affect the rate and time at which alcohol is absorbed into one’s bloodstream.
¶ 5 A statute is unconstitutionally vague if it fails to provide “person[s] of ordinary intelligence a reasonable opportunity to know what is prohibited” and fails to contain explicit standards of application to prevent arbitrary and discriminatory enforcement.
Grayned v. City of Rockford, 408
U.S. 104, 108-09,
While [a] driver may not be able to determine that his BAC is .10%, rather than .099%, such precision is not required to prevent the statute from being declared vague. Due process requires neither perfect notice, absolute precision nor impossible standards. It requires only that the language of a statute convey a definite warning of the proscribed conduct.
Id. 1
¶ 6 We can discern no meaningful difference between the argument Poshka now makes and the one addressed in
Fuenning.
And Division One of this court has likewise rejected a vagueness challenge to former § 28-692(A)(2).
State v. Martin,
¶ 7 Poshka also claims the statute permits arbitrary and discriminatory enforcement because an individual’s BAC result can vary depending on the time the test is performed, investing in police officers “unfettered discretion” in determining when to perform the test to maximize the likelihood of a higher BAC result.
See Kolender v. Lawson,
¶8 Moreover, as the state observes, the statute proscribes driving with a BAC of .08 or greater “within two hours of driving.” § 28-1381(A)(2). Rather than being susceptible to arbitrary enforcement, the statute’s
*221
terms are unambiguous and precise in identifying the prohibited conduct — having a BAC of .08 or higher within two hours of driving a vehicle. Far from being vague, the two-hour provision satisfies due process by advising that criminal penalties exist for those who risk getting behind the wheel of a car after consuming a substantial amount of alcohol.
Martin.
We therefore disagree with Poshka that the statute’s terms are so inexplicit as to grant law enforcement officers an undue measure of discretion.
Cf. Kolender,
Overbreadth
¶ 9 Poshka also contends § 28-1381 is unconstitutionally overbroad, insisting that, because “driving with a BAC under .08 is not expressly illegal, the legislature cannot make it so by testing the defendant two hours later,” and that to do so casts “too wide a net” that includes both illegal and legal conduct.
See Brown
(overbroad statutes are ones designed to punish activities that are not constitutionally protected, but include within their scope activities that are constitutionally protected). As the state correctly observes, however, Poshka lacks standing to bring an overbreadth claim here because she has not alleged that § 28-1381(A)(2) “substantially infringes upon protected First Amendment freedoms or that [s]he is a member of a class of ‘innocent defendants.’”
Martin,
Elimination of Affirmative Defense in § 28-1381(C)
¶ 10 Until recently, § 28-1381 contained, in relevant part, the following additional provision:
It is an affirmative defense to a charge of a violation of subsection A, paragraph 2 of this section if the person did not have an alcohol concentration of 0.10 or more at the time of driving ____ If a defendant produces some credible evidence that the defendant’s alcohol concentration at the time of driving ... was below 0.10, the state must prove beyond a reasonable doubt that the defendant’s alcohol concentration was 0.10 or more at the time of driving ....
See 2000 Ariz. Sess. Laws, ch. 153, § 1. The legislature had removed that portion of the statute by the time Poshka committed her offenses. See 2001 Ariz. Sess. Laws, ch. 95, § 5. Poshka argues, as she did below in a motion to dismiss the charges against her, that the legislature’s elimination of the affirmative defense clause renders § 28-1381(A)(2) violative of due process because the statutory proscription against having a BAC of .08 within two hours of driving is no longer rationally related to furthering a legitimate governmental interest. We disagree.
¶ 11 Poshka relies on language from
Martin
to argue that § 28-1381’s affirmative defense provision was the indispensable portion of the statute that saved its constitutionality. In that case, in evaluating the defendant’s allegation that the proscription against having a BAC of .10 or greater within two hours of driving was unconstitutionally vague, Division One noted that, “if one consumes alcoholic beverages within two hours after driving, with a BAC of 0.10 or more within the two-hour period but not at the time of driving, that fact may establish an affirmative defense.”
¶ 12 Under the current statute, that a defendant’s BAC at the precise time of driving may not have reached the proscribed level is irrelevant. Rather, a defendant’s BAC need only have reached .08
within two hours
of driving. § 28-1381(A)(2);
see also Sereika v. State,
¶ 13 We reject Poshka’s contention that, absent the affirmative defense, § 28-1381 no longer survives rational basis review. The legislature may prescribe what conduct is or is not lawful.
Cacaras.
The creation of the crime of having a blood alcohol level of .10 percent or greater — now .08 or greater— within two hours of driving a motor vehicle was within the purview of the legislature’s broad police power.
See id.; see also Werner v. Prins,
¶ 14 Poshka concludes her argument by reviewing other jurisdictions’ approaches to similar DUI statutes that, she contends, support her position.
See State v. Baker,
Disposition
¶ 15 For the foregoing reasons, Poshka’s convictions and the imposition of probationary terms are affirmed.
. An amendment to A.R.S. § 28-1381 reduced the threshold alcohol concentration from .10 to .08, effective September 1, 2001. 2001 Ariz. Sess. Laws, ch. 95, § 5.
