An ignition interlock device can be required under four circumstances. First, an ignition interlock device is required for anyone seeking to obtain an Ignition Interlock License. It must be installed by a certified installer and proof of the installation must be provided to the DOL prior to the issuance of any Ignition Interlock License.


An Ignition Interlock Device will also be required as a result of a criminal conviction for DUI in any District, Municipal, or Superior Court. On a conviction for a first offense DUI, the court will require an Ignition Interlock Device to be installed on all vehicles driven by the defendant for a period of 1 year. If convicted of a second DUI, the time period is 5 years. If convicted of a third DUI, the time period is 10 years. For a person convicted of DUI, the Ignition Interlock Device must be installed on all vehicles driven.


An IID may also be required for some convictions of Reckless or Negligent Driving. If you are convicted of a Reckless Driving or Negligent Driving charge that was originally filed as a DUI, and you have previous convictions for DUI or Reckless/Negligent Driving that were originally filed as a DUI, you will be required to install an Ignition Interlock Device on all vehicles you drive for a period of 6 months.


Finally, the judge in your criminal case may order you to install an Ignition Interlock Device on all vehicles you drive as a condition of pretrial release. If you have been arrested or charged with DUI, the court will ultimately have to make a decision on whether to release you from custody while your case is pending. The judge will have the discretion to order you to install an ignition interlock device on any vehicle you drive as a condition of granting you pretrial release.
