In 2005, “Melanie’s Law” came into effect which increased the penalties for operating a motor vehicle under the influence (OUI) of alcohol or controlled substances. It also established the Interlock Ignition Device (IID) program, which requires multiple OUI offenders to install an IID for a prescribed period of time.
Ignition Interlock Device (IID) Program
On October 28, 2005, the Commonwealth of Massachusetts passed new legislation known as “Melanie’s Law” increasing the penalties for operating a motor vehicle Under the Influence (OUI) of Alcohol or Controlled Substances. This change helped to usher in new and enhanced periods of license suspension or revocation and further established the Commonwealth’s Ignition Interlock Device (IID) Program. The IID program requires multiple OUI offenders to install an IID in their vehicle for a prescribed period of time. The IID program is managed by the Ignition Interlock Department of the Registry of Motor Vehicles (RMV). Massachusetts General Laws, Chapter 90, § 24, Chapter 90, § 24 ½, 540 CMR 25.00 and 801 CMR 4.02 define the rules and regulations that govern the IID program.
Melanie’s Law requires that an IID be installed and used by both drivers with a conditional “hardship” driver’s license and by those operator’s whose driver’s licenses are eligible for reinstatement following completion of the OUI license suspension or revocation periods. Any operator meeting the requirements for hardship on the OUI offense will be issued a conditional twelve hour/day hardship license with the “HT” license restriction. Any operators seeking reinstatement after completion of the OUI license suspension or revocation periods will receive a driver’s license with the “T” license restriction. The “HT” and “T” license restrictions stands for Massachusetts’ “Zero-Tolerance Policy” for drunk driving and assists law enforcement officials in identifying operators with an IID. The IID must remain installed throughout the operator’s conditional hardship license period plus two years after reinstatement of full operating privileges.
The IID regulations found at 540 CMR 25.00 were created to establish guidelines for the certification, installation, use and maintenance of the IID. Since the IID’s program inception, more than 17,000 operators have had the devices installed. Throughout the Commonwealth of Massachusetts, there are seven approved vendors that offer installation and maintenance of the IID at several convenient service provider locations.
The Registrar of Motor Vehicles formed the Drunk Driving Advisory Committee to review and discuss current RMV regulations, policies and procedures as it relates to the administration of laws governing drunk driving. The Drunk Driving Advisory Committee consists of representatives from the Executive Office of Public Safety, Governor’s Highway Safety Bureau, Department of Public Health, RMV, law enforcement and other interested parties.
An IID is a handheld breath-alcohol monitoring device (approximately the size of a cell phone) that is electronically connected to a vehicle's ignition. You are required to pass an IID Breath-Alcohol test before starting your vehicle. The IID also requires you to take breath-alcohol re-tests while you are operating the vehicle.
The IID program requires multiple offenders who have accumulated two or more convictions for OUI (Alcohol or Controlled Substances) to have the IID installed in their vehicle. Further, the RMV will honor court orders requesting that an operator install the IID for the full length of that court order.
The minimum period for an IID restriction is two years. If the IID is issued on a conditional hardship license, the IID is required for the length of that OUI license suspension or revocation period plus two years after reinstatement of full operating privileges.
The IID license restriction is not automatically removed at the conclusion of the IID license restriction period. All operators must apply to the RMV's Ignition Interlock Department to have the IID removed from their vehicle and the license restriction lifted.
Operators are responsible for the installation, maintenance, proper usage and payment of all associated IID fees.
- Installation – You must contact a vendor/service provider and schedule an IID installation.
- Maintenance Visits – You must return to the service provider once every 25-30 days from the last service visit for scheduled maintenance and data uploads.
- Proper Usage – You must follow all of the rules and guidelines you are given for using the IID and must never tamper with or try to circumvent the use of the IID.
- Payment – You must pay the vendor/service provider all of the required leasing and maintenance fees.
Operators subject to an Ignition Interlock license restriction must pay a $30 monthly program administration fee pursuant to the provisions of 801 CMR 4.02. This fee shall be collected by the IID Vendor on behalf of the Registry of Motor Vehicles (RMV) at your initial service visit (not installation) and each subsequent service visit.
Further information can be found in the FAQ section of the IID Program Document.

First, visit an RMV Service Center and speak with a RMV Hearings Officer. The RMV Hearings Officer will explain the criteria for a conditional hardship license or for full reinstatement. DO NOT have an IID installed in your vehicle before you have received approval for the IID from a RMV Hearings Officer.
Once you have been approved for a conditional hardship license or for full reinstatement, the RMV Hearings Officer will provide you with a list of approved vendors/service providers along with legal documents (affidavits) that must be completed, signed, notarized and returned to an RMV Hearings Officer. By signing these affidavits, you certify that you understand, as well as each licensed driver in your household, that you are not allowed to drive any vehicle without an IID and that you cannot try to bypass the IID in any way. The penalties for these actions are included in the affidavits(s).
You must then return to an RMV Hearings Officer with the completed affidavits. An “HT” or “T” license restriction will be added to your driver’s license. The “HT” or “T” license restriction means that you are only allowed to operate a motor vehicle equipped with an IID.
If you transfer your vehicle’s registration to a newly acquired vehicle, or obtain a new registration for an additional vehicle, you must follow the steps for IID installation. You must first seek approval from an RMV Hearings Officer to remove, transfer or add an IID to a vehicle.
You must then call an approved IID vendor/service provider to schedule an appointment for IID installation. DO NOT plan to drive yourself to the appointment – there are NO EXCEPTIONS to your requirement to drive a vehicle with an IID. When you go to your appointment, you must bring proof of your identity. The service provider will install the IID in your vehicle and give you detailed instructions on how to use and maintain the device. Throughout the Commonwealth of Massachusetts, there are seven approved vendors that offer installation and maintenance of the IID at several convenient service provider locations. See the Vendors/Service Providers Listing below.
If you do not have an IID installed in your vehicle(s) first, you will not be eligible to have your license reinstated or to schedule a permit or road test examination. You must have an IID installed in every vehicle that you own, lease or operate (including your employer’s vehicle), no exceptions are made to this requirement.
If you have been serving a license suspension for greater than two years without conditional hardship license relief or full reinstatement of operating privileges, you are required to pass a learner’s permit exam at an RMV Service Center Driver Licensing department. You are also required to take a road test in a vehicle equipped with an IID.
To schedule a road-test, contact the RMV’s Contact Center at 1-857-368-8000. A “Special” IID road-test is required when the IID vehicle is not equipped with an emergency brake in the center console area of the front seat, or if the vehicle does not provide a seat for the sponsor. A Special IID road-test is taken with a road test supervisor and must be scheduled by speaking with an RMV customer service representative.

IID Usage Requirements
Once the IID is installed in your vehicle, you will receive instructions and training from your service provider on how to operate the device. The following steps need to be taken to correctly use the device:
- Turn on the vehicle’s ignition and wait for the IID to display instructions indicating you need to take an initial breath-alcohol test.
- Blow into the IID until you have provided an acceptable breath-alcohol test sample. If you pass the initial breath-alcohol test, the IID will allow you to start your vehicle.
If you fail the initial breath-alcohol test (Blood Alcohol Concentration "BAC" greater than .02%), you will not be able to start your vehicle. You will need to wait for your BAC to decrease before you take another breath-alcohol test.
If you fail a second time within a service period, your vehicle will go into lockout and you will need to visit your service provider within 48 hours to continue operation of the vehicle. A service period is the 1-30 day period following the last IID calibration or service visit.
After the vehicle has started, you will be required to take rolling re-tests at random intervals while operating the vehicle. When it is time to take a rolling re-test, the IID will beep, alerting the operator that they have five minutes to take the breath-alcohol re-test.
You may take the rolling re-tests while driving, but it is recommended that, if it is safe to do so, you pull your vehicle over to the side of the road and take the breath-alcohol re-tests. If you do not take the rolling re-test, or if you turn the ignition off before taking the rolling re-test, this will be considered a missed test.
The IID will never shut your engine off after it has been started.
Inspection and Maintenance of IID
An operator must bring his/her vehicle to the IID service provider once every 25 – 30 days for as long as the operator is subject to the IID license restriction. At these service visits, the IID will be inspected for mechanical and functional defaults. In addition, the IID vendor/service provider will examine the IID device for tampering, a violation of the Interlock program. It is also an IID program violation to miss a service visit. If you know that you will miss a service visit, you must contact the RMV’s Ignition Interlock Department.
At each monthly service visit, an administrative fee is also collected to help cover the RMV’s cost of running the IID program. The fee is $30.00 per IID program participant and begins upon the issuance of the interlock restricted drivers permit or license.
Operators in the IID program must immediately notify the RMV’s Ignition Interlock Department (857-368-7180) with their change of address or to report a non-operational vehicle. Further, operators are required to get approval from an RMV Hearings Officer before transferring any IID between vehicles or transferring to a new IID vendor. Notification to the RMV is also required, but not limited to the following circumstances:
- Change of IID vendor/service provider
- Transfer of an IID to a new vehicle
- Adding an IID to a second vehicle
- Filing of additional licensed driver affidavits
If the IID in your vehicle goes into lockout, you have 48 hours to return to the IID service provider for a service visit. If you do not return to the IID service provider within the 48 hour time period, the IID will remain in a state of lockout and must be towed, at your expense, to the IID service provider.
A Lockout occurs when one of the following events happen:
- 2 failed start-up tests within one service period (1 - 30 days)
- 1 failed rolling retest with a blood alcohol concentration (BAC) above .02
- 1 missed service visit
- 2 missed rolling retests within one service period (1-30 days)
If you believe a lockout is improper, you may request a hearing with the RMV's Ignition Interlock Department within 30 days of the lockout.

All multiple OUI offenders with a Massachusetts Interlock obligation that live out-of-state will need to complete the two (2) year IID program and associated requisites in order to be eligible to reinstate the right to operate in Massachusetts.
Massachusetts interlock restricted operators who live outside the state must either enroll in the Massachusetts Interlock program or submit an out-of-state resident affidavit(s).The Out-Of-State Affidavit affirms that you will not operate any vehicle unless it is equipped with a functioning Ignition Interlock Device.
All operators who are licensed in the Commonwealth of Massachusetts and who are required to have an IID to operate a vehicle must continue to use an IID equipped vehicle when travelling out-of-state. Failure to use an IID and meet all IID requirements will result in the immediate suspension or revocation of your driver’s license.
Out-of-State Program Credit
An operator can receive program credit for time in which they maintain an IID in their vehicle while residing in another jurisdiction. You must be enrolled in the Massachusetts Interlock Program and meet all program requirements. You must use an IID vendor/service provider that conducts business in Massachusetts and the state where you reside, and the IID must be set to the same standards as Massachusetts.
Program requirements require IID maintenance and regularly scheduled service visits. No credit will be given if there is evidence of program violations or non-compliance. The Massachusetts Interlock Operator & Other Licensed Resident Affidavits are provided below.
Out-of-State Resident Opt-Out Policy
If a Massachusetts Ignition Interlock Device is required, you cannot drive in the state without one. If you are living out-of-state and choose not to participate in the Massachusetts IID program the interlock restriction will be added to your license until you complete the two (2) year interlock requirement. If you operate a vehicle in Massachusetts without an IID, you could face an additional license suspension as well as being subject to criminal penalties.
Massachusetts will authorize your removal from the IID program upon a showing of out-of-state residency. This release from the Massachusetts Interlock requirement enables you to apply for a license in another jurisdiction but does not satisfy program completion for Massachusetts purposes.
To complete the Opt-Out process, you must submit to the RMV’s Ignition Interlock department a completed, signed and notarized Out-of-State Affidavit along with proof of out-of-state residency. Further, all outstanding license reinstatement fees must be paid before relief is granted. The Massachusetts Interlock Operator Out-of-State Affidavit is provided below.
Additional Resources for Out-of-State Policies
Eligibility for removal of the device is based upon completing the 2 year IID program requirements and having no program lockouts or violations for a period of 6 months prior to the request for removal of the IID. If you are required to have the IID installed during the conditional hardship license period, the full term of hardship must be served plus an additional 2 years following full license reinstatement.
The length of the IID requirement is never based on the length of time the IID has been installed, but rather on meeting the appropriate periods of license suspension or revocation as prescribed by law. The Steps for IID Removal is included below.
If you remove the IID without prior RMV authorization and program completion, this early un-authorized removal will trigger an immediate license suspension. With this early un-authorized removal, you are no longer active in the IID program, receive no credit towards program completion and are subject to further administrative and criminal penalties.
Authorized Early Withdrawal
To receive approval for an early withdrawal request from the IID program, contact the RMV’s Ignition Interlock department or visit an RMV Hearing’s Officer. The IID early withdrawal request will be approved and your license/right to operate will be immediately suspended. Your license/right to operate will remain suspended indefinitely until you apply and re-enter the IID program and satisfy all IID program requirements. All time served in the IID program will be credited towards your Massachusetts IID restriction period.
