Hawaii Ignition Interlock Requirements (2026): Costs & The Only Approved Provider
Hawaii requires an ignition interlock for every OVUII (Operating a Vehicle Under the Influence of an Intoxicant) conviction and every ADLRO administrative revocation — including a first offense. The state contracts with a single statewide vendor and sets pricing by contract. There is no choice of provider. Here’s what you need to know.
| All-offender state? | Yes — IID required in all vehicles operated during the entire revocation period, including 1st offense (program launched January 2011) |
| Offense term | OVUII (Operating a Vehicle Under the Influence of an Intoxicant) — Hawaii’s term for DUI |
| Approved provider | Smart Start only — HIDOT selects a single statewide vendor under HRS §291E-6. All other providers are NOT approved. |
| Who issues the interlock permit | ADLRO (Administrative Driver’s License Revocation Office); sentencing courts also order IID |
| Duration — 1st offense (court) | 1 year to 18 months revocation with IID |
| Duration — 1st offense (ADLRO admin) | 1 year with IID |
| “Highly intoxicated” 1st offender election | May elect 2-year revocation with NO IID, instead of 18 months with IID (HRS §291E-41(b)(4)(A)) — rarely the right choice |
| Duration — 2nd offense (within 10 yrs) | 2–3 years with IID (court); 2 years (ADLRO) |
| Duration — 3rd offense (habitual, within 10 yrs) | 3–5 years with IID (class C felony); ADLRO: 4 years; highly intoxicated with prior: 6 years |
| State-contracted pricing | $84 installation + $89/month (lease + calibration) + $50 violation-lockout fee |
| Financial assistance | Yes — SNAP/EBT recipients and certain benefit program participants may qualify for reduced cost (HRS §291E-5) |
| ADLRO hearing fee | $30 (non-refundable; waivable for indigency) |
| Who certifies devices | HIDOT — Ignition Interlock Program |
| Governing law | HRS §291E-61; §291E-61.5; §291E-41; §291E-44.5; §291E-6; §291E-5 |
Hawaii’s single-vendor system
Under HRS §291E-6, HIDOT is required to select a single statewide vendor through a competitive procurement process. That vendor is currently Smart Start. Intoxalock, LifeSafer, Guardian, Dräger/RoadGuard, and ALCOLOCK are not approved in Hawaii — installing with any other company will not satisfy your ADLRO or court requirement. Verify the current vendor with HIDOT before installation since procurement cycles can change the contract.
The upside of the single-vendor system: HIDOT negotiates the pricing. The state-contracted rates are $84 for installation and $89 per month for lease and calibration combined — lower than what drivers typically pay in open-market states.
What an interlock costs in Hawaii
| Installation (state-contracted rate) | $84 |
| Monthly lease + calibration (state-contracted) | $89/mo |
| Violation-lockout fee | $50 per lockout event |
| ADLRO hearing request fee | $30 (waivable for indigency) |
Over a 12-month first-offense ADLRO term, expect roughly $1,152 in device costs ($84 + $89 × 12) at the contracted rate — one of the most predictable pricing structures in the country. Estimate your exact cost →
How to get enrolled — 5 steps
- Receive your ADLRO administrative revocation notice or court order — the IID requirement applies from the start of your revocation period.
- Apply to ADLRO for an interlock permit. Pay the $30 hearing fee (waivable for indigency). ADLRO will issue your interlock permit.
- Contact Smart Start — the sole approved vendor — and schedule installation. Bring your ADLRO permit and vehicle documentation.
- Complete the full revocation period with the device installed and active in every vehicle you operate.
- ADLRO releases your relicensing form up to 30 days before the end of revocation if your interlock permit is active. Your revoked license is not returned — you must obtain a new one from your county DMV after completing a substance-abuse assessment.
Violations and lockouts
HRS §291E-6 requires Smart Start to report failed tests and circumvention attempts to ADLRO and the courts. A violation lockout event triggers a $50 fee. The specific consequences of violations — including whether time is added to your term — are administered by ADLRO and the sentencing court; published automatic-extension rules were not located in statute. If you experience a violation or lockout, contact Smart Start and your attorney immediately to understand the implications for your specific case.
