Ignition Interlock Device Regulations

Ignition Interlock Device Regulations

Melanie’s Law requires all second or subsequent offenders to drive only those vehicles equipped with a breath alcohol ignition interlock device during the entire term of any hardship license and for a 2 year period after getting a full license reinstatement. Both the Mass. RMV and Board of Appeal strictly enforce this requirement. The Board and the Registry have a zero tolerance approach when dealing with interlock challenges.

All participants of the Registry’s Ignition Interlock Device Program are required to maintain communication with the MassDOT Ignition Interlock Department  at 857-368-7180 to report certain events  such as a change of address, non-operational motor vehicles,  lockouts caused by false readings, and other such matters.

Mass. IID program participants must obtain permission from the RMV Interlock Department prior to removing an IID or transferring it between vehicles. Authorization must be obtained prior to the removal, disconnection, or transfer.
