Ignition Interlock Laws in Maine: A Comprehensive Overview

Ignition interlock laws in Maine play a crucial role in maintaining public safety on the roadways, particularly when it comes to preventing instances of driving under the influence (DUI). These laws require specific individuals who have been convicted of a DUI to install an ignition interlock device (IID) in their vehicles. The primary function of the IID is to analyze a driver’s breath for alcohol content and prevent the vehicle from starting if the detected blood alcohol concentration (BAC) exceeds the allowable limit.

The implementation of these laws has been effective in reducing alcohol-related accidents, as well as serving as a deterrent for potential offenders. Throughout Maine, strict penalties and fines are imposed on individuals who are found to be in violation of ignition interlock laws. Additionally, these laws often include provisions for mandatory IID installation periods, which vary depending on the severity of the infraction and prior convictions.

In Maine, ignition interlock laws are continually evolving to better address the ongoing challenge of impaired driving. It is essential for drivers to be aware of their legal obligations and the potential ramifications if they fail to adhere to these regulations. By understanding and complying with these laws, drivers will contribute to creating safer roads for everyone.

Ignition Interlock Laws in Maine

Definition and Purpose

An Ignition Interlock Device (IID) is a device installed in a vehicle that requires the driver to provide a breath sample before starting the engine. The IID prevents the vehicle from starting if it detects a blood alcohol concentration (BAC) above a predefined limit. The main purpose of ignition interlock laws is to reduce the incidences of alcohol-impaired driving by ensuring that individuals with a history of driving under the influence (DUI) or driving while intoxicated (DWI) are prevented from operating a vehicle while impaired.

In Maine, ignition interlock laws aim to reduce alcohol-related traffic accidents and fatalities. These laws, along with maintaining the minimum legal drinking age at 21, provide a framework for dealing with drivers convicted of DUI or DWI offenses in the state source.

Offenses Requiring an Ignition Interlock Device

Maine requires ignition interlock devices to be installed in the vehicles of drivers convicted of certain DUI or DWI offenses. Here’s a summary of some conditions when an IID may be required:

  • First-time offenders with a BAC of 0.08% or higher but less than 0.15% may be required to install an IID for a minimum of 150 days.
  • First-time offenders with a BAC of 0.15% or higher, or if they refuse to take a chemical test, may be required to install an IID for a minimum of 275 days.
  • Repeat offenders with a prior DUI or DWI conviction within the past 10 years may be required to install an IID for a minimum of 275 days and up to 4 years, depending on the number of prior offenses and other factors.

These requirements, as well as Maine’s ignition interlock laws, serve as an additional layer of protection for the state’s residents, helping to prevent alcohol-impaired driving and the tragic consequences that often accompany such behavior source.

Ignition Interlock Device Installation and Costs

Installation Process

The installation process for Ignition Interlock Devices (IIDs) in Maine involves a few steps. Firstly, the individual must choose an approved IID provider, such as Intoxalock or Smart Start. Next, they schedule an installation appointment with the chosen provider.

During the appointment, a trained technician installs the IID in the offender’s vehicle. They also provide instructions on how to use the device properly, perform regular maintenance, and follow reporting requirements. The individual is responsible for paying installation and monthly service fees.

Financial Assistance

Some individuals may struggle with the financial burden of IID installation and upkeep, especially those facing high costs. Maine law mandates that IID providers must offer financial assistance to eligible clients.

Eligibility is determined based on the individual’s income and household size. Financial assistance can help partially or fully cover the costs of the IID installation and monthly service fees. In order to qualify, one must contact the chosen IID provider and provide necessary documentation to demonstrate financial need.

Monitoring and Maintenance

Routine Inspections

In Maine, ignition interlock devices (IIDs) must undergo regular inspection and maintenance to ensure proper functioning and compliance. These inspections are conducted by authorized service providers, who are also responsible for calibrating the device and checking for any signs of tampering or malfunctions. The frequency of routine inspections varies, and may depend on the specific terms of the individual’s required interlock program.

During inspections, the service provider will also download data logs from the ignition interlock device to be analyzed by monitoring authorities. This data, including any failed breath tests and other violation attempts, is important for evaluating the offender’s progress in the program and determining any necessary actions or penalties.


Ignition interlock device violations can occur for various reasons, such as attempting to start the vehicle with a blood alcohol concentration (BAC) above the pre-set limit, failing a rolling retest, or attempting to tamper with or bypass the device. In Maine, monitoring agencies are responsible for assessing these violations and deciding on appropriate consequences.

A common violation is the rolling retest. The IID may prompt the driver to provide a breath sample at random intervals while the vehicle is in use. Failing to complete a rolling retest or registering a BAC over the limit during a rolling retest is considered a violation.


The specific consequences for violating ignition interlock device regulations depend on the severity of the violation and the individual’s prior record. Potential penalties may include extension of the IID program duration, suspension or revocation of driving privileges, fines, or even jail time in more serious cases.

For example, if a violation involves a rolling retest, the vehicle may need to be serviced by the monitoring agency within a specified time period, or it could be disabled. Repeat offenders may face more severe consequences, such as increased fines or license suspension.

By following guidelines and adhering to the monitoring and maintenance requirements for ignition interlock devices in Maine, individuals can reduce the likelihood of violating the regulations and facing the associated penalties.
