Information on New Jersey DWI and Ignition Interlock Laws


In New Jersey, anyone driving with a blood alcohol concentration (BAC) of .08 or greater is considered to be DUI. However, a judge may order an ignition interlock device (IID) for anyone arrested driving with a BAC of .08 or over.

Every situation and state is unique, please consult with your attorney or your state licensing authority to confirm your requirements and obligations.

First-time DUI offenders in New Jersey whose BAC is .15 or higher, as well as offenders who refuse to submit to an alcohol test, must install an IID in their vehicles during license suspension and for six months to one year following license restoration. Repeat offenders must have an interlock installed during license suspension and for a period of one to three years after license restoration.

When you are convicted of a DUI, you must immediately turn your license over to the court. New Jersey does not have a temporary or work license option and you may not drive while your license is suspended. For the duration of the interlock period, you may not drive any vehicle other than one in which an IID has been installed. Failure to have an ignition interlock installed when ordered could result in an additional one-year driving privilege suspension. If you’re convicted of a DUI you will be required to be complete an Intoxicated Driver Program (IDP) at an Intoxicated Driving Resource Center (IDRC).
