New Jersey Ignition Interlock Requirements

  • §39:4-50(a)(1), (2) and (3); §39:4-50.17

 *If your license was suspended for a DUI offense, the court may require you to get an ignition interlock device to prevent a vehicle from starting if your BAC exceeds 0.05%.

  • First DUI offense: Installation of interlock device for six months to one year upon restoration (judge’s discretion); BAC 0.15% or greater requires mandatory installation of ignition interlock device during license suspension and for 6 months to 1 year following restoration
  • Second DUI offense: Mandatory installation of interlock device during license suspension and for 1 to 3 years following restoration

If the court sentences you to get an interlock device, you will receive a notice of suspension from MVC with instructions on how to obtain the device. IMPORTANT NOTE: Failure to have an ignition interlock installed when ordered by a judge could result in an additional one year driving privilege suspension. For installation availability for motorcycles and autocycles please contact the listed manufacturers directly.
