You may be required to use an ignition interlock device (IID) as a condition of a hardship license in Massachusetts and you may be ignition-interlock required for a period of 2 years after getting your license fully reinstated, as explained below.
On January 1, 2006, the ignition interlock provision of Melanie’s Law went into effect. The purpose of the law was to enhance public safety by requiring that any repeat DUI offender who is reinstating a license that was suspended or revoked for operating under the influence (OUI) must drive only those vehicles equipped with a certified ignition interlock device while on any hardship, work, or Cinderella license and for an additional 2 years after having the hardship hours removed from the license. There are no exceptions to this rule. Therefore, if you are a repeat DUI offender and you have been granted hardship relief, in addition to the “H” restriction, you will have a “Z” restriction which denotes that you must only drive vehicles equipped with ignition interlock devices. The Registry will require you to have this “Z” restriction for 2 years after you have the “H” restriction removed.
The event which triggers the IID requirement is not the underlying DUI the convictions but the request for a new license in the form of either a hardship license or full reinstatement. If this occurs on or after January 1, 2006, and driver has multiple DUI convictions, he or she will be ignition interlock required, even if the DUI suspension results from an our conviction which occurred prior to the enactment of the ignition interlock law.
