DUI Laws in Hawaii: Penalties, BAC Limits & License Suspension

In Hawaii, drunk driving is charged as "Operating a Vehicle Under the Influence of an Intoxicant" — OVUII, not DUI or DWI. The per se legal limit is a breath or blood alcohol concentration (BAC) of 0.08% for regular drivers. And separate from any criminal case, Hawaii's Administrative Driver's License Revocation Office (ADLRO) can take your license before you're ever convicted of anything — if you want to fight that administrative revocation, you generally have only about 6 calendar days after the review decision is issued to request the expedited hearing schedule, and an absolute outside limit of 60 calendar days from your arrest before you lose the right to a hearing entirely. If you were just arrested, read the "what to do" section below before anything else.

What the Offense Is Called in Hawaii

Hawaii Revised Statutes (HRS) Chapter 291E calls the offense Operating a Vehicle Under the Influence of an Intoxicant, abbreviated OVUII. You may still hear people call it "DUI," but on your citation, court paperwork, and license notices, it will say OVUII. The core statute is HRS §291E-61, and repeat/habitual OVUII is covered separately under HRS §291E-61.5.

BAC Limits in Hawaii

• Standard drivers (21 and older): 0.08%. This is the nationwide per se threshold — at or above it, you're presumed impaired as a matter of law under HRS §291E-61, regardless of how you seemed to be driving.
• Commercial driver's license (CDL) holders operating a commercial vehicle: 0.04%. This lower federal-floor threshold applies whenever you're behind the wheel of a commercial vehicle. When you're driving your own personal, non-commercial car, the standard 0.08% limit applies instead.
• Drivers under 21: 0.02%. Hawaii does not have a true "zero tolerance" rule at exactly 0.00% — instead, HRS §291E-64 makes it a separate offense for anyone under 21 to drive with a "measurable amount of alcohol," defined as a BAC of 0.02% or more but less than 0.08%. If a driver under 21 tests at 0.08% or higher, they're charged with standard adult OVUII instead, which carries heavier consequences.
• "Highly intoxicated driver" enhancement at 0.15% or above. Hawaii adds extra mandatory jail time and extra mandatory license revocation on top of the standard first-offense penalties when BAC is 0.15% or higher. Treat this as a real threshold, not a minor technicality — confirm the current add-on amounts with the court, since legislative penalty amendments happen periodically.

Implied Consent and Refusing a Chemical Test

By driving on Hawaii roads, you've already agreed — under the state's implied consent law in HRS Chapter 291E — to take a breath, blood, or urine test if lawfully arrested for OVUII. Refusing is not a way to avoid consequences:

• A first refusal triggers its own automatic license revocation, separate from the revocation for a first BAC failure and commonly at least one year. Confirm the exact current figure with ADLRO, since revocation lengths are tied to your specific prior-offense history.
• Refusing does not make the case go away. Prosecutors can still charge OVUII based on officer observations, field sobriety tests, and other evidence, and your refusal itself can be introduced against you in court.
• Repeat refusals within the lookback window carry progressively longer revocations, similar to repeat convictions.

This article is not telling you whether to take or refuse a test — that's a decision with real tradeoffs you should think through with a Hawaii criminal defense attorney if you have time before deciding, or as soon as possible afterward.

The Administrative License Revocation: Hawaii's ADLRO Deadline (Time-Critical)

Most states run this through a "DMV." Hawaii is different: the agency is the Administrative Driver's License Revocation Office (ADLRO), a division of the Hawaii State Judiciary — not the counties' driver-licensing offices. ADLRO can revoke your license administratively based purely on the arrest and test result (or refusal), independent of whatever happens in the separate criminal OVUII case.

Here is the sequence, and why speed matters:

1. At arrest, you're issued a Notice of Administrative Revocation (NOAR), which also functions as a temporary driving permit — valid for about 30 days for an alcohol-related arrest (about 44 days for a drug-related arrest).
2. ADLRO conducts an administrative review of the revocation.
3. If you want the expedited hearing schedule to contest the revocation, your written request generally needs to reach ADLRO within about 6 calendar days of the review decision.
4. Request a hearing after that but within 60 calendar days of the NOAR date, and it can still be scheduled, though on a slower track. After 60 days, ADLRO generally will not schedule a hearing at all, meaning the revocation simply stands.

Because the timeline is this compressed, do not wait to see how the criminal case goes before dealing with ADLRO — the two processes run on separate tracks, and the administrative clock does not pause for your court date. Contact ADLRO or a Hawaii OVUII defense attorney within days of your arrest, not weeks, and verify the current deadlines and forms directly with ADLRO, since timing details are updated from time to time.

First-Offense Penalties If Convicted

If you are convicted of a first OVUII in Hawaii, HRS §291E-61 requires the following in some combination. Statutory dollar and day figures can shift with legislative amendments, so confirm current numbers with the court or a local attorney rather than relying on any figure you read online, including this one:

• License revocation: a mandatory revocation of not less than one year and not more than eighteen months for a first offense (longer if BAC was 0.15% or above).
• Ignition interlock device (IID): installation of an IID on all vehicles you operate is required during the revocation period, at your own expense.
• Substance abuse program: a mandatory alcohol/drug education and counseling program of at least 14 hours.
• Fine and/or jail or community service: the statute provides a fine range plus either a short jail term or a community-service alternative for a first offense; the exact amount depends on the current statute and the judge's discretion. Confirm current figures before assuming any specific number.

A second offense within the lookback period, and a third-or-later offense, carry substantially longer revocations, mandatory treatment, higher fines, and — at the felony level — prison exposure (see below).

Lookback (Washout) Period: How Long a Prior OVUII Counts

Hawaii uses a 10-year lookback period. A prior OVUII (or habitual-OVUII) conviction within the 10 years before your current offense counts toward enhanced second-, third-, or habitual-offender penalties. An OVUII from more than 10 years ago generally does not count for enhancement purposes, though it can still surface in other contexts (insurance, employment, immigration).

When OVUII Becomes a Felony in Hawaii

OVUII is usually a misdemeanor, but it becomes a felony — specifically, "Habitually Operating a Vehicle Under the Influence of an Intoxicant" under HRS §291E-61.5, a class C felony — when a driver has accumulated enough qualifying prior OVUII/habitual convictions within the 10-year lookback (commonly triggered at a third qualifying offense within that window, with escalating exposure beyond that). Separately, causing serious bodily injury or death while driving impaired can expose a driver to felony charges under Hawaii's negligent injury and negligent homicide statutes, layered on top of (or instead of) the OVUII charge itself, regardless of prior record. If any of these circumstances apply to your case, the exposure is significantly higher than a standard first- or second-offense OVUII, and you should get a criminal defense attorney involved immediately.

What to Do After a DUI (OVUII) Arrest in Hawaii

1. Read your NOAR paperwork the day you get it. It states your temporary permit's expiration date and the revocation ADLRO intends to impose — these dates are running whether or not you've hired a lawyer yet.
2. Contact ADLRO or a Hawaii OVUII attorney immediately — within days, not weeks. The window to request an administrative hearing is short (roughly 6 calendar days after the review decision for the expedited track, with a hard outer limit around 60 days from arrest). Missing it can mean losing your right to challenge the license revocation entirely, separate from whatever happens in criminal court.
3. Do not drive past your temporary permit's expiration without confirming your legal status. Driving on a revoked license adds a separate, serious charge.
4. Preserve your own timeline and evidence — note the time of the stop, any tests given, what was said, and get contact information for any witnesses, while it's fresh.
5. Do not discuss the facts of your arrest with anyone other than your attorney, including on social media or with insurance adjusters, before you've gotten legal advice.
6. Ask a Hawaii criminal defense attorney about the ignition-interlock permit process if you need to keep driving — Hawaii allows an interlock-restricted permit in many cases, which can let you drive legally sooner than waiting out a full revocation.
7. Track both cases separately on your calendar — the ADLRO administrative case and the criminal OVUII case in court are not the same proceeding, have different deadlines, and can reach different outcomes.
