      What Happens if I Refuse an OUI Test in Massachusetts?

      The state of Massachusetts has an implied consent law. An implied consent law means anyone who is driving has agreed to have their blood or breath tested for alcohol if they are stopped by law enforcement. Refusing a test can result in a license suspension of 180 days for first offenders, three years for second offenders, and five years for third offenders. The driver’s vehicle could be impounded for 12 hours of the offense, and the RMV will be notified of the license suspension within 24 hours.

      How Can I Regain Driving Privileges in Massachusetts?

      Some drivers can get driving privileges back if they install an IID and meet other criteria. These criteria include: 

      • Hold a valid MA license at the time of the offense
      • Can’t have operated a vehicle since the suspension
      • Install an interlock from a state-approved provider and provide proof of the installation
      • Wait out the necessary portion of the suspension period if required
      • If applying for a hardship license*, must show documented proof of the hardship with a letter from your employer verifying your work schedule - this letter cannot be more than 30 days old
      • Pay any fees or fines required
      • Finish jail sentence or court-ordered community service or treatment
      • Enroll in/or have completed the 24D alcohol education program
      • Attend any RMV hearings required

      *Offenders seeking an interlock restricted license after completing their related OUI suspension period do not need to prove a hardship.

      Offenders might have to meet additional criteria depending on the circumstances of the offense.
