Hawaii Ignition Interlock Permit: Application, Eligibility, and IIP Requirements

What the IIP Does

An Ignition Interlock Permit (IIP) is the primary way to maintain limited driving privileges during an OVUII-related license revocation in Hawaii. With an IIP, you can legally operate personal vehicles that have a state-approved ignition interlock device installed — a breathalyzer wired to the ignition that requires a clean breath sample before the engine will start.

Without an IIP, driving is illegal once your 30-day temporary permit expires after an OVUII arrest. For most first-offense drivers, the choice is between an IIP and not driving for a year.

Who Is Eligible

Eligibility hinges on one central requirement: you must have held a valid, unexpired driver's license at the time of your arrest. The ADLRO will not issue an IIP if your license was already expired, suspended, or revoked for any other reason before the OVUII arrest.

Additional exclusions:

• Drivers under 18 at the time of arrest
• Holders of learner's permits or instruction permits
• Individuals with a BAC of 0.15% or higher (first offense) — extended to an 18-month mandatory revocation with no restricted permit
• Chemical test refusal cases may still qualify for an IIP, but the revocation period extends to 2 years and carries enhanced monitoring

CDL holders can obtain an IIP, but they must agree to restrict their driving to Category 1, 2, or 3 passenger vehicles. The IIP does not permit commercial vehicle operation.

How to Apply

The IIP application process runs through the ADLRO, not the county DMV. You need three documents:

1. ADLRO Form 3 (Application for Ignition Interlock Permit) — filled out completely with your case number
2. Signed Smart Start Lease Agreement — proving the device has been installed on your vehicle. Smart Start is the only state-approved vendor in Hawaii.
3. Proof of valid motor vehicle insurance — for the specific vehicle with the interlock device installed

Submit all three to the ADLRO in person, by mail, by fax (808-534-6888), or by email ([email protected]) in PDF, JPG, JPEG, or PNG format.

The sequence matters: you need to contact Smart Start and schedule installation before you can complete the IIP application, because the lease agreement proving installation is a required attachment. If you're planning to have an IIP ready before your 30-day temporary permit expires, start the Smart Start process early.

Smart Start Installation and Costs

Smart Start operates service centers across the major Hawaiian islands. The installation takes roughly 60 to 90 minutes and includes wiring the breathalyzer unit and camera to your vehicle's ignition system.

Current pricing:

• One-time installation: $84
• Monthly lease and calibration: $89/month
• Program violation lockout reset: $50 per occurrence

Drivers receiving SNAP/EBT benefits from Hawaii's Department of Human Services may qualify for a 50% discount on installation and monthly fees. This requires a formal DHS verification letter — not just a physical EBT card — containing your name, active case number, and benefit amount.

How the Device Works Day-to-Day

Every time you start the vehicle, you blow into the device. The camera photographs you during the sample. A BAC reading below 0.04% allows the engine to start normally. At 0.04% or above, the vehicle won't start and the event is logged as a violation.

While driving, the device triggers random rolling retests — a prompt requiring another breath sample. If you fail or skip a retest, the device activates the horn and headlights as an alert (it doesn't shut off the engine for safety reasons). Failed retests and skipped retests are both logged as violations.

Every 30 days, you must bring the vehicle to a Smart Start center for calibration and data download. This appointment is mandatory — missing it counts as a program violation.

What Counts as a Violation

Program violations have teeth. Each one extends your revocation period and can trigger criminal charges under HRS § 291E-62:

• Blowing 0.04% BAC or higher on startup or rolling retest
• Missing a 30-day calibration appointment
• Failing or skipping a rolling retest
• Tampering with the device, wiring, or camera
• Having someone else blow into the device (the camera catches this)

Adding or Changing Vehicles

If you need to add the interlock device to a different vehicle or update driver information on your IIP, file ADLRO Form 5 (Application for Amended Ignition Interlock Permit). Each vehicle you want to drive must have its own Smart Start device installed.

Getting the IIP Before Day 30

The practical advice is to start the Smart Start installation process as early as possible after arrest — ideally within the first two weeks. Coordinating the Smart Start appointment, getting the lease agreement, gathering insurance documents, and submitting Form 3 to the ADLRO all take time. Running this in parallel with the ADLRO hearing process (Form 12 by Day 3, Form 8 within 6 days of the review decision) ensures you maintain driving privileges when the temporary permit expires on Day 30.

The Hawaii First-Offense DUI Guide integrates the IIP application timeline with the ADLRO hearing deadlines so both processes stay coordinated.
