Ignition Interlock Laws in Hawaii: Key Regulations and Requirements

Ignition interlock laws aim to reduce the incidence of drunk driving by requiring individuals convicted of driving under the influence (DUI) or driving while intoxicated (DWI) to install a device in their vehicle. These devices, known as ignition interlocks, function by measuring the driver’s blood alcohol content (BAC) through a breath sample. If the BAC level exceeds the preset limit, the vehicle will not start. In the Aloha State, the ignition interlock laws play a crucial role in promoting road safety and preventing alcohol-related accidents.

Hawaii has a measurable amount of alcohol laws in place, making it illegal to drive with any detectable amount of alcohol in one’s system. These laws, coupled with the ignition interlock requirements, serve to deter intoxicated driving and ultimately save lives. Between 2009 and 2018, there were significant reductions in alcohol-impaired driving incidents in Hawaii. Efforts to further enhance and enforce ignition interlock laws can lead to even greater improvements in road safety.

All 50 states, including Hawaii, have some form of ignition interlock law. The specific provisions and requirements can vary by state, with 27 states mandating the installation of an interlock device for all convicted DWI offenders, regardless of the offense severity. The implementation of these laws has led to a decrease in alcohol-related accidents nationwide, highlighting their effectiveness in curbing drunk driving behavior. Residents of Hawaii and beyond should continue to be aware of and support initiatives aimed at enhancing road safety through ignition interlock laws.

Ignition Interlock Laws Overview

Purpose and Goals

The purpose of ignition interlock laws is to reduce the occurrence of alcohol-impaired driving and associated risks. These laws mandate the installation of ignition interlock devices (IIDs) in the vehicles of individuals convicted of driving under the influence (DUI) offenses. The ultimate goals of these laws are to enhance public safety, reduce recidivism, and deter drunk driving.

An ignition interlock device is a breathalyzer-like device that connects to the vehicle’s ignition system. It requires the driver to provide a breath sample before starting the car. If the device detects a blood alcohol content (BAC) level above a specific threshold, it prevents the vehicle from starting, thus effectively combating the risk of impaired driving.

Scope and Applicability

In Hawaii, ignition interlock laws apply to individuals convicted of DUI offenses, including first-time offenders. State law requires the use of an IID for a period determined by the court, based on the nature of the offense and the offender’s history. Additionally, the law mandates the installation and maintenance of the IID at the offender’s expense, and participants must also complete a substance abuse evaluation and treatment program.

The ignition interlock laws reflect Hawaii’s commitment to addressing the problem of impaired driving, ensuring that those who have demonstrated a risk to public safety take the necessary steps to prevent future instances of driving under the influence. As a result, these laws play a significant role in reducing alcohol-related motor vehicle crashes and fatalities on Hawaii’s roads.

Requirements and Procedures

Installation and Maintenance

In Hawaii, ignition interlock devices (IID) are required for repeat DUI offenders and others depending on the severity of their offense. To ensure the device’s effectiveness, proper installation and maintenance are crucial. After a court order, individuals must have the IID installed by a state-approved service provider. A complete list of approved providers can be found at the Hawaii Department of Transportation’s website.

Once installed, the IID must be maintained regularly, usually every 60 days, to ensure it functions correctly. During these maintenance appointments, the service provider checks the device for tampering or malfunctions and downloads the data logs. If violations are detected, they might be reported to law enforcement or the court.

User Responsibilities

Individuals ordered to install an IID must adhere to certain responsibilities while using the device:

  • Payment: Offenders are usually responsible for all costs associated with the IID, including installation, maintenance, and monitoring fees. However, Hawaii has implemented an ignition interlock indigent fund, which covers a portion of the IID expenses for those who cannot afford them.
  • Regular Maintenance: As mentioned earlier, the IID must be maintained regularly, usually every 60 days, to ensure it functions correctly and remains compliant with the court order.
  • Breath Samples: Users are required to provide breath samples before starting their vehicle and during random rolling retests while driving. Failure to provide a sample or providing a sample with a blood alcohol concentration (BAC) above the allowed limit may result in further penalties.
  • Driving Restriction Compliance: Individuals with an IID may be subject to additional driving restrictions, such as limited driving hours, that must be followed throughout the IID restriction period.
  • Record Keeping: It is essential to keep a record of all installation, maintenance, and monitoring documents, as they may be required for court review, license reinstatement, or other legal purposes.

By following the appropriate installation, maintenance, and user responsibilities, individuals can ensure compliance with Hawaii’s ignition interlock laws and reduce the risk of further legal penalties.

License Reinstatement Process


In Hawaii, individuals with a suspended driver’s license due to a DUI offense may be eligible for license reinstatement with the installation of an ignition interlock device. According to Hawaii’s ignition interlock laws, the interlock device prevents impaired driving by connecting to a vehicle’s ignition and requiring the driver to first pass an alcohol breath test.

To be eligible for reinstatement, individuals must meet the following requirements:

  • Completion of any required alcohol education or treatment programs
  • Payment of all necessary fines and fees
  • Proof of installation of an approved ignition interlock device

Application Steps

For those who are eligible for license reinstatement, the following steps must be taken to apply for an Interlock device:

Step 1: Obtain a certificate of completion from the mandatory alcohol education or treatment program.

Step 2: Contact an approved ignition interlock provider in Hawaii to schedule the installation of the device. A list of providers can be found here.

Step 3: Submit the certificate of completion and a receipt of interlock device installation to the Hawaii Driver’s License Office.

Step 4: Pay any outstanding fines and fees associated with the DUI offense and license reinstatement.

Once these steps have been completed, the individual’s driver’s license may be reinstated with the condition of maintaining the ignition interlock device for the required period.

Penalties for Non-Compliance

Fines and Sanctions

Non-compliance with ignition interlock laws in Hawaii can result in various fines and sanctions. Offenders who fail to comply may face an extension of their ignition interlock period. Some states, like Hawaii, may impose financial penalties for non-compliant behavior. These penalties can include fines and fees related to the ignition interlock device, such as installation and monitoring costs. Moreover, the driver’s license may be suspended or revoked as an additional penalty1.

Criminal Charges

In addition to fines and sanctions, non-compliance with ignition interlock laws may also lead to criminal charges. Depending on the severity of the offense and the individual’s prior history, these charges can range from misdemeanors to more severe felonies2.

It is essential for drivers in Hawaii to understand and adhere to the ignition interlock requirements to avoid these penalties and potential legal consequences. By complying with the law, individuals can work towards regaining their driving privileges and maintaining a clean driving record.
