Hawaii’s Ignition Interlock Device Laws

Hawaii FlagIn the State of Hawaii, the first time a person is convicted of driving under the influence (DUI), the person is required to install an ignition interlock device (IID) on all vehicles driven by the person, commercial as well as household. The offender is responsible for paying all costs associated with the device, including installation, calibration, and monitoring. If a person cannot afford the monthly maintenance cost of the IID, the company that provides the device will offer lower costs.

Running retests are standard in Hawaii, meaning that the driver will need to provide breath samples at random times during a single trip. The IID will let the driver know when to breathe into the device, giving him or her enough time to pull over and provide a breath sample. If the offender fails the retest, the vehicle’s horn will honk and lights will flash to alert law enforcement officers. Every month the IID must be taken to a service station to download the information stored on the device.

The length of time an offender must use an IID varies:

  • One (1) year for the first offense
  • Eighteen (18) months for the second offense
  • Two (2) years for the third offense

Three (3) or more DUI convictions within ten (10) years may result in a felony charge and five (5) years in prison.
