The Registry of Motor Vehicles has determined that the following actions or inactions will constitute ignition interlock violations and these may result in 10 year or lifetime license revocations. Massachusetts appears to have the strictest Ignition Interlock Violations in the country and the Registry enforces IID program rules with a zero-tolerance approach. Fortunately, if you have been accused of an ignition interlock violation, you have the right to a hearing at the RMV in Boston and you have the right to be represented by a lawyer that that hearing. Given the harsh consequences, skilled legal representation is strongly recommended.

  • Operating without a certified Ignition Interlock Device
  • Soliciting or allowing another person to blow into an Ignition Interlock Device so that the person whose license has the IID restriction can operate the vehicle

  • Attempting to circumvent or tamper with the Ignition Interlock Device
  • A single failed rolling re-test which registers a reading at or above .05
