DWI Sentence and Interlock Law

Police officer holding a breathalyzer

Today, August 23, 2019, Governor Phil Murphy signed a DWI bill that revises penalties for drunk driving and ignition interlock device violations. This bill reduces the length of driver’s license suspensions for drunk driving and refusing to submit to a breathalyzer test, but increases ignition interlock devices for these offenses. The “IID” is a device that detects alcohol from breath samples it takes from the driver. If alcohol is detected, the vehicle’s engine will not start. Please look at the comparisons outlined below in order to understand the shorter suspension lengths and longer Ignition Interlock Device installation requirements.

New Law

  • First-time offenders:
    • If BAC is between .08-.10, the court will order the driver to forfeit their license for a period of three months or until the driver installs an ignition interlock device
    • If BAC is higher than .10, but less than .15, the driver’s must forfeit their license until they install an ignition interlock device
    • If BAC is higher than .15, the driver must forfeit their license for four to six months and have an IID installed during and after the suspension for nine to 15 months.
    • If one refuses to submit to a breathalyzer, the driver’s license is suspended for a period between seven months to a year or until the driver installs an ignition interlock device
  • Ignition Interlock Device (IID)
    • Mandatory for first-time offenders during suspension and following
      • BAC between .08-.10 – required installation for three months
      • BAC between .10-.15 – required installation for seven months to one year
      • BAC over .15 – required installation of one year to eighteen months
      • If required, it is installed for six months to a year
    • Multiple convictions
      • Required installation on each motor vehicle the offender owns or operates
    • Failure to Install IID
      • Driver’s license suspension for eighteen months
