Hawaii DUI laws: OVUII at .08, a 6-day ADLRO fast-hearing deadline, and mandatory interlock through most revocation periods

Hawaii's DUI law is best explained as an OVUII system with separate court sentencing and ADLRO license-revocation tracks. The adult offense covers impairment by alcohol or drugs and per se alcohol at 0.08, while Hawaii separately penalizes drivers under 21 for operating with a measurable amount of alcohol. On the criminal side, a first OVUII with no prior conviction in ten years brings a one- to eighteen-month revocation, ignition interlock during the revocation period, substance-abuse programming, and jail, community service, or fines. On the administrative side, ADLRO generally issues an alcohol-case review decision within eight calendar days, requests made within six days of mailing keep the statutory fast-hearing schedule, and refusal raises the revocation ladder to two, four, or eight years. Hawaii also treats 0.15 as highly intoxicated and escalates both court and administrative consequences, while habitual OVUII becomes a felony.

Open official source View Hawaii services
Adult OVUII trigger Adult OVUII covers impairment by alcohol or drugs or an alcohol concentration of 0.08 or more in breath or blood
Highly intoxicated threshold A measurable alcohol concentration of 0.15 or more triggers Hawaii's highly intoxicated driver enhancements
ADLRO hearing timing If ADLRO revokes your license after administrative review, a hearing request made within 6 calendar days of the mailed decision keeps the statutory fast-hearing schedule
Habitual OVUII rule A driver with two or more prior OVUII convictions within 10 years, or a prior habitual OVUII conviction, faces felony habitual OVUII treatment

Overview

What this page helps you verify

A strong Hawaii DUI page should lead with the state's actual OVUII structure instead of flattening everything into one first-offense chart. Hawaii splits the subject between criminal sentencing under HRS chapter 291E and an administrative revocation process handled by ADLRO. The details that matter most in practice are the ten-year lookback, the 0.15 highly-intoxicated trigger, the refusal-based administrative revocation ladder, the separate under-21 measurable-alcohol offense, and the fact that ignition interlock is central if a driver wants to keep driving during most revocation periods.

Usually needed

Documents and information to prepare

  • The notice of administrative revocation and any ADLRO review decision showing the revocation dates and conditions
  • The citation, charging document, plea paperwork, or sentencing order showing whether the case is a first, repeat, highly intoxicated, or habitual OVUII matter
  • A driving record, traffic abstract, or other official record showing prior alcohol or drug enforcement contacts or prior OVUII convictions within the relevant lookback period
  • Proof of completion of any court- or ADLRO-required substance-abuse assessment, education, counseling, or treatment
  • Proof of ignition interlock installation on all vehicles you operate, plus the insurance or self-insurance proof required for an ignition interlock permit

Typical flow

What the process often looks like

  1. Treat a Hawaii DUI arrest as two problems right away: the criminal OVUII case and the ADLRO administrative license case.
  2. Figure out whether the case is standard adult OVUII, under-21 measurable-alcohol, highly intoxicated, or habitual OVUII, because the penalties change materially by category.
  3. If ADLRO mails an unfavorable review decision and you want the faster statutory hearing track, request the hearing within 6 calendar days of the mailing date instead of waiting.
  4. Complete the assessment, treatment, interlock, and relicensing requirements before trying to drive again, because Hawaii often keeps the license unusable even after part of the case is over.

Core offense rules

Hawaii's DUI law uses the OVUII label and reaches both impairment-based and per se alcohol cases

The adult offense is broader than a simple 0.08 chart.

  • HRS section 291E-61 says a person commits OVUII by operating or assuming actual physical control of a vehicle while impaired by alcohol, while impaired by drugs, with 0.08 or more grams of alcohol per two hundred ten liters of breath, or with 0.08 or more grams of alcohol per one hundred milliliters or cubic centimeters of blood.
  • Hawaii separately defines a highly intoxicated driver as a person with 0.15 or more grams of alcohol in blood or breath.
  • For drivers under 21, HRS section 291E-64 creates a separate offense for operating with a measurable amount of alcohol instead of relying only on the adult 0.08 OVUII threshold.

Court-side penalties

The court sentencing ladder uses a 10-year lookback and turns a third serious case into felony territory

This is the main place generic benchmark pages tend to oversimplify Hawaii.

  • For a first OVUII offense not preceded within ten years by a prior conviction, HRS section 291E-61 requires a fourteen-hour minimum substance-abuse program, a license revocation of no less than one year and no more than eighteen months, ignition interlock during the revocation period, and community service, jail, or a fine.
  • For an offense within ten years of a prior OVUII conviction, the statute raises the substance-abuse program to at least thirty-six hours, increases the revocation to no less than two years and no more than three years, keeps ignition interlock in place, and raises the jail or community-service exposure and fine range.
  • If the driver was highly intoxicated, HRS section 291E-61 adds extra mandatory imprisonment and extra revocation time on top of the base first- or repeat-offense sentence.
  • HRS section 291E-61.5 says habitual OVUII is a class C felony, and a highly intoxicated habitual OVUII case becomes a class B felony with permanent revocation.

ADLRO and refusal

Hawaii's administrative revocation track moves quickly and refusal makes it much harsher

The ADLRO case can matter even before the criminal case is resolved.

  • HRS section 291E-41 sets administrative revocations at one year, two years, or four years when the record shows zero, one, or two or more prior alcohol or drug enforcement contacts in the preceding ten years.
  • For highly intoxicated drivers, the same section increases the first-tier administrative options to either eighteen months with mandatory ignition interlock or two years without the mandatory-interlock track, then three years for one prior contact and six years for two or more.
  • If the respondent refuses testing after the statutory implied-consent warnings, HRS section 291E-41 says the administrative revocation periods rise to two years, four years, or eight years.
  • HRS section 291E-38 gives the respondent six days from the date the administrative review decision is mailed to request a hearing and keep the statutory fast schedule, and the Judiciary's ADLRO FAQ says alcohol-case review decisions are generally issued within eight calendar days of arrest.

Interlock and driving eligibility

In Hawaii, ignition interlock is usually the only practical way to drive during an OVUII revocation

This is the compliance rule users most often miss.

  • HRS section 291E-44.5 says ADLRO shall issue an ignition interlock permit after proof of installation and compliant insurance or self-insurance, if the driver is otherwise eligible.
  • The same statute says no ignition interlock permit may issue if the driver's license was already expired, suspended, or revoked from another action, if the driver did not hold a valid license at the time of arrest, or if the driver held only a learner's or instruction permit.
  • The ADLRO FAQ says no hearing is required just to apply for an ignition interlock permit, but if you do not install the device, Hawaii's revocation terms generally become an absolute no-driving period.

Under-21 cases

Hawaii treats under-21 drinking-and-driving as a separate measurable-alcohol offense with its own penalty ladder

That separate statute matters because it is not just a lighter version of adult OVUII.

  • HRS section 291E-64 says a person under twenty-one may not operate a vehicle with a measurable amount of alcohol.
  • For a first under-21 violation not preceded within five years by a prior alcohol enforcement contact, the statute requires a one-hundred-eighty-day prompt suspension, although a person age eighteen or older may receive a minimum thirty-day absolute suspension followed by limited work-and-treatment driving for the remainder of the one-hundred-eighty-day period.
  • A second under-21 violation within five years brings a one-year prompt suspension, and a third within five years brings a two-year revocation.
  • If a person under twenty-one refuses testing after arrest under HRS section 291E-64, HRS section 291E-65 authorizes a twelve-month first refusal suspension and a two- to five-year range for later refusals.

Accuracy notes

Where people get tripped up

  • Hawaii DUI content should use the state's OVUII terminology and keep the separate under-21 measurable-alcohol offense visible instead of flattening everything into the adult 0.08 rule.
  • Do not merge court sentencing and ADLRO revocations into one chart. Hawaii treats them as related but separate tracks with different timing and different lookback mechanics.
  • The 0.15 highly-intoxicated threshold materially changes both criminal and administrative outcomes and should stay near the top of the page.
  • Ignition interlock is central to Hawaii relicensing and mid-revocation driving. A page that discusses only fines or jail time misses the main operational consequence.

FAQ

Common questions

  • What BAC is illegal for DUI in Hawaii?

    For most adult drivers, Hawaii's per se OVUII threshold is 0.08 in breath or blood. Hawaii also allows an OVUII charge based on actual impairment by alcohol or drugs, even apart from the 0.08 per se measurement.

  • What does Hawaii mean by a highly intoxicated driver?

    Hawaii defines a highly intoxicated driver as someone with 0.15 or more grams of alcohol in blood or breath. That status adds extra criminal penalties and increases administrative revocation consequences.

  • How fast do I need to act if ADLRO revokes my license?

    If you want the statutory fast-hearing track, Hawaii says the hearing request must be made within 6 calendar days after the administrative review decision is mailed. The Judiciary's ADLRO FAQ also says alcohol-case review decisions are generally issued within 8 calendar days after arrest.

  • Can I drive during a Hawaii OVUII revocation?

    Usually only if you qualify for an ignition interlock permit and install the device on every vehicle you operate. Hawaii does not issue that permit if your license was already expired, suspended, or revoked from another case or if you did not hold a valid license at the time of arrest.

  • When does a Hawaii DUI become a felony?

    Hawaii's habitual OVUII statute makes the case a class C felony when the driver already has two or more prior OVUII convictions within ten years or a prior habitual OVUII conviction. If the habitual case also involves a highly intoxicated driver, the statute elevates it to a class B felony.
