Haw. Rev. Stat. § 291E-3
(a) In any criminal prosecution for a violation of section 291E-61 or 291E-61.5 or in any proceeding under part III:
(3) The presence of one or more drugs in an amount sufficient to impair the person's ability to operate a vehicle in a careful and prudent manner,
within three hours after the time of the alleged violation as shown by chemical analysis or other approved analytical techniques of the person's blood, breath, or urine shall be competent evidence that the person was under the influence of an intoxicant at the time of the alleged violation.
(b) In any criminal prosecution for a violation of section 291E-61 or 291E-61.5, the amount of alcohol found in the defendant's blood or breath within three hours after the time of the alleged violation as shown by chemical analysis or other approved analytical techniques of the defendant's blood or breath shall be competent evidence concerning whether the defendant was under the influence of an intoxicant at the time of the alleged violation and shall give rise to the following presumptions:
(c) In any criminal prosecution for a violation of section 291E-61 or in any proceeding under part III:
(2) .15 or more grams of alcohol per two hundred ten liters of the person's breath,
within three hours after the time of the alleged violation as shown by chemical analysis or other approved analytical techniques of the person's blood or breath shall be competent evidence that the person was a highly intoxicated driver at the time of the alleged violation.
[L 2000, c 189, pt of §23; am L 2004, c 90, §3; am L 2007, c 198, §2; am L 2010, c 166, §6; am L 2021, c 216, §2]
Where a plain reading of this section indicates that the phrase "any proceeding under part III" refers to administrative license revocations, trial court erred in upholding hearing officer's ruling that subsection (c) applies only to criminal prosecutions and has no application to administrative driver's license revocation office cases. 109 H. 220, 124 P.3d 965 (2005).
