Ignition Interlock Device in Massachusetts

100% ConfidentialFreeNo Obligation

In Massachusetts, the use of an Ignition Interlock Device (IID) is a significant aspect of the state’s approach to dealing with OUI offenses. The IID is a breathalyzer for an individual’s vehicle, requiring the driver to provide a breath sample before the engine starts. In 2005, the Commonwealth passed Melanie’s Law which created harsher penalties for repeat OUI offenders. One of the critical aspects is the requirement for subsequent OUI offenders to install Ignition Interlock Devices in their vehicles. 

The IID is a small, electronic device installed in a vehicle’s dashboard. It requires the driver to provide a breath sample before the vehicle can be started. If the breath sample indicates a blood alcohol concentration (BAC) above the programmed limit (0.02% in Massachusetts), the vehicle will not start.

Who Needs an Ignition Interlock Device?

In Massachusetts, the requirement to install an Ignition Interlock Device primarily applies to individuals who have been convicted of multiple OUI offenses. Specifically, anyone who is convicted of a second or subsequent DUI offense in Massachusetts is required to install an IID in their vehicle as a condition for regaining their driving privileges. The minimum period for an Ignition Interlock Device restriction is two years.

Furthermore, the use of IIDs will also extend to first-time DUI offenders who are seeking a hardship license. Conditions of a hardship license will require an IID to be installed into the driver’s vehicle.

  • Eligible for a hardship license
  • 2 years after your license is reinstated (+ time during hardship)
  • 1st time offenders who blew a .15 or above at the time of arrest

Operator Requirements and Responsibilities

The installation, carried out by state-approved vendors, and maintenance of the IID fall under the responsibility of the offender, including all associated costs. Regular calibration and maintenance are crucial to ensure the device’s accuracy and functionality. The IID records all breath test results, and this data is periodically reviewed by authorities, influencing the offender’s driving privileges.

How Does the IID Work?

The core functionality of the IID is to require the driver to take a breathalyzer test before starting the vehicle. When the driver blows into the device, it analyzes the breath sample for alcohol content, specifically measuring the Blood Alcohol Concentration (BAC). The device is programmed with a pre-set BAC threshold, often set at a conservative level such as 0.02%, which is below the legal limit for driving. If the driver’s BAC is below this threshold, the IID allows the vehicle to start. However, if the BAC is above the limit, the device prevents the engine from starting. To maintain continuous sobriety checks, the IID also requires what are known as ‘rolling re-tests.’ These are additional breath tests that occur at random intervals during the journey, ensuring that the driver remains sober throughout.

Ignition Interlock Device Program Violations

Violating the Ignition Interlock Device program in Massachusetts can lead to serious consequences. These violations can take several forms, including failing a breath test, tampering with the device, or failing to comply with the required maintenance and monitoring procedures. When a violation occurs, it is typically recorded by the IID and reported to the appropriate authorities during regular maintenance checks.

These violations can lead to a range of penalties, including an extension of the duration for which the IID must be used, an increase in the frequency of maintenance and reporting, monetary fines, or in severe cases, revocation of driving privileges. Particularly egregious violations, such as tampering with the IID, could result in criminal charges and potential jail time.

It is crucial for individuals in the IID program to strictly adhere to its requirements. The consequences of non-compliance extend beyond legal implications, impacting lifestyle and financial stability. In situations where there are disputes or misunderstandings about alleged violations, consulting with a legal professional specializing in OUI cases and familiar with the IID program in Massachusetts is advisable.
